The unit rate of change of ddd with respect to ttt is 4/3.

To graph the proportional relationship between ddd and ttt, we first need to find the unit rate of change. Since an increase of 333 units in ttt corresponds to an increase of 444 units in ddd, we can calculate the unit rate as follows:

Unit Rate = (Change in ddd) / (Change in ttt) = 444 / 333 = 4/3

So, a change of 1 unit in ttt corresponds to a change of 4/3 units in ddd.

Now, let's graph the relationship. The equation representing this proportional relationship is:

ddd = (4/3)ttt

This is a linear relationship with a slope of 4/3 and passes through the origin (0,0). To plot the graph, start at the origin and use the slope to plot additional points, such as:
- For ttt = 3, ddd = 4 (since 4/3 * 3 = 4)
- For ttt = 6, ddd = 8 (since 4/3 * 6 = 8)

Plot these points and draw a straight line through them, representing the proportional relationship between ddd and ttt. The unit rate of change of ddd with respect to ttt is 4/3.

Lee spent a total of 33 hours working on all the lawns, as calculated by multiplying the number of lawns for each size category by the respective time required for mowing, trimming, and sweeping.

In order to determine the total number of hours Lee spent working on all the lawns, we need to calculate the time for each task separately. For the average size lawn, Lee takes 1 hour to mow and 2 hours to trim and sweep, totaling 3 hours per lawn. For the large size lawn, Lee takes 3 hours to mow and 3 hours to trim and sweep, totaling 6 hours per lawn.

Given that Lee mowed, trimmed, and swept 5 average size lawns and 3 large size lawns in one week, we can calculate the total hours as follows:

Total hours for average size lawns = 5 lawns * 3 hours/lawn = 15 hours

Total hours for large size lawns = 3 lawns * 6 hours/lawn = 18 hours

Therefore, the total hours Lee spent working on all the lawns is 15 hours + 18 hours = 33 hours.

In conclusion, Lee spent a total of 33 hours working on all the lawns, as calculated by multiplying the number of lawns for each size category by the respective time required for mowing, trimming, and sweeping.

A geometric sequence is a type of sequence where each term is found by multiplying the previous term by a constant factor. This means that each term is a multiple of the one before it. In contrast, an arithmetic sequence is a type of sequence where each term is found by adding a constant value to the previous term.

This means that each term is a sum of the one before it and a fixed value.

To answer your question, whether a geometric sequence will always grow faster than an arithmetic one depends on the values of the constant factor and fixed value in each sequence. In general, if the constant factor in a geometric sequence is greater than 1, the terms will grow at an increasingly faster rate than in an arithmetic sequence.

However, if the constant factor is between 0 and 1, the terms will grow at a decreasing rate, meaning that the sequence will actually grow more slowly than an arithmetic one.

It's important to note that the rate of growth is not the only factor to consider when comparing geometric and arithmetic sequences. The actual values of the terms in each sequence can also differ significantly, depending on the starting term and the values of the common ratio and common difference.

In some cases, an arithmetic sequence may actually have higher values than a geometric one, even if it grows more slowly.

In summary, whether a geometric sequence will always grow faster than an arithmetic one depends on the specific values of each sequence. However, in general, if the constant factor in a geometric sequence is greater than 1, it will grow faster than an arithmetic sequence.

we can simplify |x + 3| to x + 3 when x is greater than 5.

The absolute value function |x| is defined as the distance of x from zero on the number line. This means that |x| is always non-negative, so it can be expressed as a non-negative number.

In this case, we are given that x > 5, which means that x is greater than 5. If we add 3 to both sides of this inequality, we get:

x + 3 > 5 + 3

x + 3 > 8

This tells us that x + 3 is also greater than 8. Therefore, when x is greater than 5, the expression |x + 3| represents the distance of x + 3 from zero, which is equal to x + 3 itself because x + 3 is positive.

As a result, we can simplify |x + 3| to x + 3 when x is greater than 5.

The linear function rule that models the total cost y​ for any number of sweatshirts x would be: y = 9.50x

What is Algebraic expression ?

An algebraic expression is a combination of variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. It may contain one or more terms, with each term separated by a plus or minus sign. Algebraic expressions are used in algebra to represent mathematical relationships and formulas.

To write a linear function rule that models the total cost y​ (in dollars) for any number of sweatshirts x, we can use the equation of a line which is given as:

y = mx + b

where m is the slope of the line and b is the y-intercept.

In this case, the slope represents the cost per sweatshirt, which is $7.00, and the y-intercept represents the fixed cost, which is the shipping charge of $2.50. Therefore, the linear function rule that models the total cost y​ for any number of sweatshirts x can be written as:

y = 7x + 2.50

If the shipping charge applied to each sweatshirt, the linear function rule would change. In this case, the cost per sweatshirt would be the sum of the base cost of $7.00 and the shipping charge of $2.50, which is $9.50. Therefore, the linear function rule that models the total cost y​ for any number of sweatshirts x would be: y = 9.50x

The number of milligrams of sugar his spoon holds is 1250 milligrams.

To find out how many milligrams of sugar Chad's spoon holds, we first need to know how much sugar he removed in total. To do this, we can subtract the amount of sugar he needed (280 grams) from the amount he poured (295 grams).

295 grams - 280 grams = 15 grams

Next, we need to divide the total amount of sugar Chad removed (15 grams) by the number of spoonfuls he used (12).

15 grams ÷ 12 = 1.25 grams per spoonful

Finally, we can convert grams to milligrams by multiplying by 1000.

1.25 grams x 1000 = 1250 milligrams

Therefore, Chad's spoon holds 1250 milligrams of sugar.

The incorrect statement about the intersecting triangles is A. CG ≅ FG.

With intersecting triangles, it is not always guaranteed that segments like CG and FG will be congruent. The lengths of CG and FG will depend on the specific configuration of the chords and their intersection point G.

However, CE/EG = FD/DG statement is TRUE. This is a consequence of the Intersecting Chords Theorem. When two chords intersect inside a circle, the products of their segments are equal.

Since ∠CEG ≅ ∠FDG intersect inside a circle, the corresponding intercepted arcs create equal angles at the intersection point. Therefore the statement is true.

ΔCEG ~ ΔFDG is also true because we know that the triangles share an angle and have proportional sides.

Using the Law of Sines and Cosines, we get all possible values of ∠H are approximately 60.6° and 69.0°.

We can use the Law of Cosines to find the length of side GH

GH² = g² + h² - 2gh cos(G)

GH² = (9.3)² + (9.6)² - 2(9.3)(9.6)cos(109°)

GH ≈ 3.585 cm

Next, we can use the Law of Sines to find the measure of angle H

sin(H)/GH = sin(G)/HI

sin(H)/3.585 = sin(109°)/HI

sin(H) ≈ 3.585(sin 109°)/HI

H ≈ arcsin[3.585(sin 109°)/HI]

Since we do not know the length of side HI, we cannot determine the exact value of angle H. However, we can find the possible range of angle H by assuming that HI is the longest side of the triangle (making angle H the smallest) and the shortest side of the triangle (making angle H the largest).

If HI is the longest side, then H ≈ arcsin[3.585(sin 109°)/9.3] ≈ 60.6°

If HI is the shortest side, then H ≈ arcsin[3.585(sin 109°)/9.6] ≈ 69.0°

Therefore, the possible values of angle H are between approximately 60.6° and 69.0°.

Answer:

1) 1/2 + 1/4 = 2/4 + 1/4 = 3/4

2) To add these fractions, you need to find a common denominator. The smallest common multiple of 7 and 9 is 63, so we can write:

3/7 * 9/9 + 2/9 * 7/7 = 27/63 + 14/63 = 41/63

3) To add these fractions, you need to find a common denominator. The smallest common multiple of 5 and 15 is 15, so we can write:

3/5 * 3/3 + 1/15 * 1/1 = 9/15 + 1/15 = 10/15

But we can simplify this fraction by dividing both the numerator and denominator by 5:

10/15 = 2/3

4) To add these fractions, you need to find a common denominator. The smallest common multiple of 9 and 8 is 72, so we can write:

1/9 * 8/8 + 7/8 * 9/9 = 8/72 + 63/72 = 71/72

5) To add these fractions, you need to find a common denominator. The smallest common multiple of 7 and 21 is 21, so we can write:

6/7 * 3/3 + 2/21 * 1/1 = 18/21 + 2/21 = 20/21

6) To add these fractions, we need to find a common denominator first. The smallest number that both 6 and 10 divide into is 30. So, we convert 4/6 to 20/30 by multiplying both the numerator and denominator by 5, and we convert 2/10 to 3/15 by multiplying both the numerator and denominator by 3. Now we have:

20/30 + 3/15 = (20x1 + 3x2)/(30x2) = 23/60

Therefore, 4/6 + 2/10 = 23/60.

7) To add these fractions, we need to find a common denominator first. The smallest number that both 11 and 22 divide into is 22. So, we convert 1/11 to 2/22 by multiplying both the numerator and denominator by 2, and we convert 3/22 to 3/22 (it is already in terms of 22). Now we have:

2/22 + 3/22 = (2 + 3)/22 = 5/22

Therefore, 1/11 + 3/22 = 5/22.

8) To add these fractions, we need to find a common denominator first. The smallest number that both 4 and 20 divide into is 20. So, we convert 1/4 to 5/20 by multiplying both the numerator and denominator by 5, and we convert 8/20 to 8/20 (it is already in terms of 20). Now we have:

5/20 + 8/20 = (5 + 8)/20 = 13/20

Therefore, 1/4 + 8/20 = 13/20.

9) To add these fractions, we need to find a common denominator first. The smallest number that both 7 and 9 divide into is 63. So, we convert 4/7 to 24/63 by multiplying both the numerator and denominator by 3, and we convert 2/9 to 14/63 by multiplying both the numerator and denominator by 7. Now we have:

24/63 + 14/63 = (24 + 14)/63 = 38/63

Therefore, 4/7 + 2/9 = 38/63.

10) To add these fractions, we need to find a common denominator first. The smallest number that both 10 and 30 divide into is 30. So, we convert 6/7 to 18/30 by multiplying both the numerator and denominator by 3, and we convert 2/30 to 1/15 by multiplying both the numerator and denominator by 15. Now we have:

18/30 + 1/15 = (18x1 + 1x2)/(30x2) = 37/30

Therefore, 6/7 + 2/21 = 37/30.

Answer:

C. Scalene

Step-by-step explanation:

Equilateral triangle has all sides equal.

Isosceles triangle has exactly 2 sides equal.

All side lengths in a Scalene triangle are distinct.

The slope of this graph is equal to 2.

In Mathematics and Geometry, the slope of any straight line can be determined by using this mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

By substituting the given points into the formula for the slope of a line, we have the following;

Slope, m of graph = (80 - 0)/(100 - 60)

Slope, m of graph = 80/40

Slope, m of graph = 2.

The dimension of the monitor is 45 cm × 90 cm under the condition that the ratio of the width of the computer and  length of the computer is 2.1.

The given ratio of length to width of a computer monitor is 2:1. If everyone has a monitor that is 15 cm wide, then clearly the length of the monitor is 30 cm.

Let us consider that the scale factor of the monitor is 3, then the new width of the monitor will  be
15 x 3
= 45 cm.

Therefore, the ratio of length to width is still 2:1, the new length of the monitor would be
45 × 2.1
≈ 90 cm

Hence, the dimensions of a monitor that has a scale factor of 3 are 45 cm x 90 cm.

The first hotel is approximately 0.6246 meters away from the dock, and the second hotel is approximately 0.4931 meters away from the dock.

To solve this problem, we can use trigonometry and create a system of equations based on the given angles and distances. Let's assume the distance between the dock and the first hotel is x meters and the distance between the dock and the second hotel is y meters.

Using the law of sines, we can relate the angles and distances:

For the first hotel:

sin(49°) = y / x     ...(Equation 1)

For the second hotel:

sin(56°) = x / y     ...(Equation 2)

We can rearrange Equation 1 to solve for y:

y = x * sin(49°)

Substituting this value of y into Equation 2:

sin(56°) = x / (x * sin(49°))

sin(56°) = 1 / sin(49°)

Now, we can solve for x by isolating it:

x = sin(56°) * sin(49°)

Plugging in the values and evaluating the equation:

x = 0.8290 * 0.7539

x ≈ 0.6246

Therefore, the distance between the dock and the first hotel (x) is approximately 0.6246 meters.

To find the distance between the dock and the second hotel (y), we can substitute this value back into Equation 1:

y = 0.6246 * sin(49°)

y ≈ 0.4931

Hence, the distance between the dock and the second hotel (y) is approximately 0.4931 meters.

In summary, the first hotel is approximately 0.6246 meters away from the dock, and the second hotel is approximately 0.4931 meters away from the dock.
