Step-by-step explanation:

cone: attached picture below

composite shape: To calculate the area of a composite shape you must divide the shape into rectangles, triangles or other shapes you can find the area of and then add the areas back together. You may have to calculate missing lengths before finding the area of some of the shapes.

Answer 2

Answer:

Cone

Surface area:

A = πr(r + l) r = √(10² - 8²) = √36 = 6A = 3.14(6)(6 + 10) = 301.44#1A = 25π, C = ?A = πr² ⇒ 25π = πr² ⇒ r² = 25 ⇒ r = 5C = 2πr = 2*3.14*5 = 31.4#2A = 5*7 + (5 - 2)*4 + 1/2*4*(6 - (5 - 2)) = 35 + 12 + 6 = 53#10

Scale factor

k = 3/4

Area is a function of two dimensions, each has k applied

The ratio of areas is the k² = (3/4)² = 9/16

Option C

Volume of prism:

V = Bh = 1/2(8*5)*6 = 120

Volume of pyramid:

V = 1/3Bh = 1/3(8*5)*9 = 120

Option A, same volume

Ratio of areas:

20/45 = 4/9

Scale factor is:

k² = 4/9k = √4/9k = 2/3

3. The material Santiago will use to build the ramp costs $2.20 per square foot. What will the total cost of building the ramp be?

Answers

Answer:

262 square feet

Step-by-step explanation:

The required expression model for the cost of the ramp is y = 2.20x.

What are equation models?

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Let the area of the ramp be x and the cost to build the ramp be y,

According to the question,
The material Santiago will use to build the ramp costs $2.20 per square foot.

Total cost = 2.20 × area of the ramp

Substitute the variable in the above expression,

y = 2.20x

The above equation represents the equation model for the cost of ramp y for the x square foot area of the ramp.

Thus, the required expression model for the cost of the ramp is y = 2.20x.

A jar contains nickels and dimes. There is a total of 25 coins in the jar. The value of the coins is $1.75. How many nickels and how many dimes are in the jar?

Answers

Answer:

15 nickels and 10 dimes

Step-by-step explanation:

Dimes - d, dime = 10c, total dimes = 10dNickels - n, nickel = 5 c, total nickels = 5n$1.75 = 175 c

Equations:

d + n = 2510d + 5n = 175

Multiply the first equation by 5 and subtract from the second one:

10d + 5n - 5d - 5n = 175 - 1255d = 50d = 10

travelled at an average speed of 85 km/h instead?
min

Answers

Answer:

18 minutes earlier

Step-by-step explanation:

Given

[tex]Distance =119km[/tex]

[tex]Speed\ 1 = 70km/h[/tex]

[tex]Speed\ 2 = 85km/h[/tex]

Required

Determine how much sooner if traveled at speed 2 instead of speed 1

Speed is calculated as:

[tex]Speed = \frac{Distance}{Time}[/tex]

Make Time the subject

[tex]Time= \frac{Distance}{Speed }[/tex]

For Speed 1

[tex]Time= \frac{119km}{70km/h}[/tex]

[tex]Time= 1.7hr[/tex]

For Speed 2

[tex]Time= \frac{119km}{85km/h}[/tex]

[tex]Time= 1.4hr[/tex]

Calculate the difference

[tex]Difference = 1.7hr - 1.4hr[/tex]

[tex]Difference = 0.3hr[/tex]

Convert to minutes

[tex]Difference = 0.3*60\ min[/tex]

[tex]Difference = 18\ min[/tex]

If traveled at 85km/h, the van will arrive 18 minutes earlier

Answers

Answer:

sorry I can't know the answer

The scale factor used is {k} = 164.4.

What is scale factor?

Scale factor is the ratio of original dimensions to the scaled dimensions.

Given is that Eiffel Tower is 986 feet tall. Caroline built a scale model that is 6 inches tall.

We can write the scale factor as -

{k} = 986/6

{k} = 164.4

Therefore, the scale factor used is {k} = 164.4.

A planr leaves and flies due north at 280 miles per hour. AT the same time another plane takes off from the same airport and flies due east at a speed of 300 miles per hour. WHat is the distnace between the two planes after 1 hour

Answers

Answer:

Distance between the two planes after 1 hour = 410 miles

Step-by-step explanation:

Given - A plane leaves and flies due north at 280 miles per hour. At

the same time another plane takes off from the same airport

and flies due east at a speed of 300 miles per hour.

To find - What is the distance between the two planes after 1 hour ?

Proof -

Given that , Plane 1 flies due north at a speed of 280 miles per hour.

So,

Total distance traveled in 1 hour = 280 miles

Also,

Plane 2 flies due east at a speed of 300 miles per hour.

So,

Total distance traveled in 1 hour = 300 miles.

The diagram is as follows :

Now,

We have to find the distance after 1 hour i.e. AC

In Triangle ABC ,

By using Pythagoras theorem, we get

AC² = BC² + AB²

⇒AC² = (300)² + (280)²

⇒AC² = 90,000 + 78,400

⇒AC² = 168,400

⇒AC = √168,400

⇒AC = 410.366 ≈ 410

∴ we get

Distance between the two planes after 1 hour = 410 miles

Find the slope of the line using the two given points.

(0, -2) and (3, 4)

Answers

Answer:

m = 2

Step-by-step explanation:

Using the slope formula, we can find the slope of two points:

y2 - y1

m = --------------

x2 - x1

The slope is the same thing as change in y over change in x. Now, plugging in the points (0, -2) and (3, 4):

4 - (-2) 4 + 2 6

m = ----------- = ------- = ------ = 2

3 - 0 3 3

So the slope is 2.

The equation representing the cost c in dollars and different amounts of meat in pounds p, is c = 7p

What is an equation?

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, A butcher displays the cost, in dollars, of different amounts of meat in the table shown.

Finding the unit price,

3 pounds = $21

1 pound = 21/3 = $7

Therefore, if c is cost and p is total pounds,

c = 7p

Hence, the equation representing the cost c in dollars and different amounts of meat in pounds p, is c = 7p

Consider Functions F and G

Answers

Answer:

Step-by-step explanation:

We are given two functions:

[tex]\displaystyle f(x)=\frac{x-16}{x^2+6x-40}\text{ and } g(x)=\frac{1}{x+10}[/tex]

And we want to find:

[tex]f(x)+g(x)[/tex]

Thus:

[tex]\displaystyle =\frac{x-16}{x^2+6x-40}+\frac{1}{x+10}[/tex]

We can factor the denominator of the first term:

[tex]\displaystyle =\frac{x-16}{(x+10)(x-4)}+\frac{1}{x+10}[/tex]

In order to add the two terms, we must have a common denominator. To achieve this, we can multiply to second term by (x - 4). Therefore:

[tex]\displaystyle =\frac{x-16}{(x+10)(x-4)}+\frac{1}{x+10}\Big(\frac{x-4}{x-4}\Big)[/tex]

Multiply:

[tex]\displaystyle =\frac{x-16}{(x+10)(x-4)}+\frac{x-4}{(x+10)(x-4)}[/tex]

Combine:

[tex]\displaystyle =\frac{(x-16)+(x-4)}{(x+10)(x-4)}[/tex]

Simplify:

[tex]\displaystyle =\frac{2x-20}{(x+10)(x-4)}[/tex]

We can expand the denominator:

[tex]\displaystyle =\frac{2x-20}{x^2+6x-40}[/tex]

Therefore, our answer is A.

Answers

Answer:

a. 35 degrees

b. 145 degrees

Step-by-step explanation:

a. Since the two base angles of this triangle are congruent, we can conclude that the triangle is isosceles, which means that the two base angles and sides are congruent.

Now, knowing that information, we can subtract 110 from 180 (the sum of all interior angles in a triangle) and we get 70. But this isn't our answer. This is the sum of both base angles. Since the base angles are congruent, we can divide the 70 by 2 to get the measure of ONE base angle, which is 35 degrees.

b. There are two approaches to solve this problem. I have worked both out.

1) We can use the Exterior Angle Theorem, which states that the sum of the interior angles is equal to the exterior angle. We can add 110 to 35, so we get 145 degrees as the measure of <1.

2) The second approach is supplementary angles. Since we see that one of the base angles and <1 is on the same line, we can subtract 35 from 180 to find the measure of <1 to get 145 degrees.

Either way you use, you get the correct answer. Hope this helped!
