Answer:

Kaya's answer is correct.

Step-by-step explanation:

The number of dots in successive figures are

8, 16, 24.

So Kaya's solution 8n is correct.

When n = 1, first square = 8*1 = 8 dots

n = 2: second square = 8*2 = 16

n = 3, 3rd square = 8*3 = 24.

If I have interpreted Kianna's formula correctly

for n = 1, then the number of dots = 2(1+ 1)^2 - 2(1 - - 1)^2

= 0.

Answer:

sec35°

Step-by-step explanation:

sec325° = sec(360 - 325)° = sec35°

The secant of a positive acute angle of sec 325° = sec 35° = 1.22077

What are Trigonometric Ratios?

Trigonometry values are all about the study of standard angles for a given triangle with respect to trigonometric ratios.The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

Given data ,

The trigonometric ratio is = sec 325°

Now , to express the ratio in terms of a positive acute angle , we take the four quadrants of the graph and express the angle in the first quadrant.

And , 325° lies on the 4th Quadrant , where all cosines and secants are positive.

Therefore , sec 325° = sec ( 360° - 35° )

                                  = sec ( 35° )

                                  =1.22077

Hence , the secant of a positive acute angle of sec 325° = sec 35° = 1.22077

The length of the side BC is 6 units

Step-by-step explanation:

Distance Between two Points in the Plane

Given two points A(x1,y1) and B(x2,y2), the distance between them is:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

We need to calculate the distance between B(7,5) and C(7,-1):

[tex]d=\sqrt{(7-7)^2+(5+1)^2}[/tex]

[tex]d=\sqrt{36}[/tex]

d=6

The length of the side BC is 6 units

Answer:

The slope calculator determines the slope or gradient between two points in the Cartesian coordinate system. The slope is basically the amount of slant a line has, and can have a positive, negative, zero or undefined value. Before we can use the calculator it is probably worth learning how to find the slope using the slope formula. To find the equation of a line for any given two points that this line passes through, use our slope intercept form calculator.

How to find slope

Identify the coordinates (x₁,y₁)and(x₂,y₂). We will use the formula to calculate the slope of the line passing through the points (3,8) and (-2, 10).

Input the values into the formula. This gives us (10 - 8)/(-2 - 3).

Subtract the values in parentheses to get 2/(-5).

Simplify the fraction to get the slope of -2/5.

Check your result using the slope calculator.

To find the slope of a line we need two coordinates on the line. Any two coordinates will suffice. We are basically measuring the amount of change of the y-coordinate, often known as the rise, divided by the change of the x-coordinate, known the the run. The calculations in finding the slope are simple and involves nothing more than basic subtraction and division.

The slope formula

slope = (y₂ - y₁) / (x₂ - x₁)

Notice that the slope of a line is easily calculated by hand using small, whole number coordinates. The formula becomes increasingly useful as the coordinates take on larger values or decimal values.

It is worth mentioning that any horizontal line has a gradient of zero because a horizontal line has the same y-coordinates. This will result in a zero in the numerator of the slope formula. On the other hand, a vertical line will have an undefined slope since the x-coordinates will always be the same. This will result the division by zero error when using the formula.

Other related topics

Just as slope can be calculated using the endpoints of a segment, the midpoint can also be calculated. The midpoint is an important concept in geometry, particularly when inscribing a polygon inside another polygon with the its vertices touching the midpoint of the sides of the larger polygon. This can be obtained using the midpoint calculator or by simply taking the average of each x-coordinates and the average of the y-coordinates to form a new coordinate.

Answer:

20

Step-by-step explanation:

7+4=11

11*5= 55

4*5=20 :)

The number of children and adults will be 35 and 20, respectively.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

You go into the store and observe the folks in queue. There are 7 adults and 4 children. If this ratio remains constant and there are 55 people in the store.

7x / 4x = constant

Then the equation is given below.

7x + 4x = 55

11x = 55

x = 11

Then the number of adults is given as,

7x = 7 (5) = 35

Then the number of children is given as,

4x = 4 (5) = 20

The number of children and adults will be 35 and 20, respectively.

Answer:

x = 1

Step-by-step explanation:

Solve for x:

4 x + 1 + 3 = 8

Hint: | Group like terms in 4 x + 1 + 3.

Grouping like terms, 4 x + 1 + 3 = 4 x + (1 + 3):

4 x + (1 + 3) = 8

Hint: | Evaluate 1 + 3.

1 + 3 = 4:

4 x + 4 = 8

Hint: | Isolate terms with x to the left hand side.

Subtract 4 from both sides:

4 x + (4 - 4) = 8 - 4

Hint: | Look for the difference of two identical terms.

4 - 4 = 0:

4 x = 8 - 4

Hint: | Evaluate 8 - 4.

8 - 4 = 4:

4 x = 4

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 4 x = 4 by 4:

(4 x)/4 = 4/4

Hint: | Any nonzero number divided by itself is one.

4/4 = 1:

x = 4/4

Hint: | Any nonzero number divided by itself is one.

4/4 = 1:

Answer:

$994.5

Step-by-step explanation:

At an opening of a new art gallery, the owner hired a caterer to serve light snacks. The owner created a budget for 150 people to attend the opening, with a per person food cost of $4.25.

Cost for 150 persons =

150 × $4.25 = $637.5

If the number of guests attending the opening was 56% more than expected, then how much was the final food cost?

Percentage increase = Final value - Initial value /Initial value

56% = x - 150/150

Cross Multiply

0.56 × 150 = x - 150

84 = x - 150

x = 150 + 84

x= 234 people

56% increase means 84 extra people came

Total people that came = 234 people

From the question, we know that: per person food cost of $4.25.

Hence

1 person = $4.25

234 persons =

234 × $4.25

= $994.5

Therefore, the final food cost is $994.5

The ton is the greatest of the units here.

The weight order of the units are

1 gram<1 pound<1 kg<1 ton.

flowers or leaves are generally very small in size so the best unit to measure the weight would be gram.

The weight in pound can be converted to gram as

1 pound =453.592 grams.

Answer:  1407.5 hours

Step-by-step explanation:

 Okay so looking at the problem, the conversion factors we are going to need are from days to hours and from minutes to hours. Let's start with the days to hours first. If there are 24 hours in a day and we have 58 days then 24x58 would get us the hours that we need. So we would get 1392 hours. Add that to the hours already present and you get 1407 hours and 30 minutes. Since 30 minutes is half of one hour you can either use a fraction or decimal to give your answer: 1407.5 hours or  hours
