Answer:

79.82

(Rounded to the nearest dollar 80)

Step-by-step explanation:

Surface area of Cylinder:

Circle:

π[tex]r^{2}[/tex]=

1π = π

so since there are 2 circles it is 2π

Rectangle:

length*width=

3*Circumference

3*(2π)=

6π

Add them all together:

2π + 6π = 8π

≈ 8*3.14

so the answer is approximately 79.82

Hope this helps :)

Answer:

8.5

Step-by-step explanation:

BF * EF = CF * DF

7 * 17 = CF * 14

119 = CF * 14

CF = 119 / 14

CF = 8.5

Answer: The surface area is 452.39in²

Step-by-step explanation:

Formula

A=4πr²

d= 2 r

Solving for A

A=πd²=π·12²≈452.38934in²

The surface area of a sphere that has a diameter of 12 inches is 452.39 in².

To solve the question, we need to know what the surface area of a sphere is.

The surface area of a sphere is given by A = 4πr² where

Given that d = 12 inches, r = d/2 = 12 in/2 = 6 in

Substituting the value of r into A, we have

A = 4πr²

A = 4π × (6 in)²

A = 4π × 36 in²

A = 144π in²

A = 452.39 in²

So, the surface area of a sphere that has a diameter of 12 inches is 452.39 in².

0/6

Step-by-step explanation:

given points are (-3,0) and (3,0)

using the slope equation y^2 - y^1/ x^2 - x^1, where

-3=x^1

3=x^2

0= y^2 and y^1 because they have the same value

0 - 0/3 - -3

0/6

Therefore, the slope is equal to 0/6

Please find attached the required triangle drawn with Microsoft Visio

Step-by-step explanation:

The isosceles triangle ΔPQR we are to construct has the following parameters;

∠PQR = 90°

Length of side hypotenuse PR = 4 cm

Therefore, given that the triangle is right triangle is an isosceles triangle the length of each of the side legs are equal

Therefore, we have;

Length of PQ = Length of QR

The length of the legs , [tex]\overline {PQ}[/tex] and [tex]\overline {QR}[/tex], are given by Pythagoras's theorem as follows;

[tex]\overline {PR}[/tex] = √([tex]\overline {PQ}[/tex]² + [tex]\overline {QR}[/tex]²) = √([tex]\overline {PQ}[/tex]² + [tex]\overline {PQ}[/tex]²) = [tex]\overline {PQ}[/tex]·√2

∴ [tex]\overline {PQ}[/tex] = 4 cm/(√2) = 2·√2 cm = [tex]\overline {QR}[/tex]

Answer:

Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form. Standard notation is the normal way of writing numbers.

Answer:

Scientific notation: c * 10^n where 1 <= c < 10

Now standard notation is basically multiplying c * 10^n out

For example:

Scientific notation: 4.5 * 10^4

Would be written as 45000 in standard notation (either multiply by 4.5 * 10^4 or just simply move the decimal in 4.5 four places to the right)

For example:

Scientific notation: 0.6 * 10^-3

Would be written as 0.0006 in standard notation (either multiply by 4.5 * 10^-3 or just simply move the decimal in 0.6 three places to the left)

Answer:

y = -x + 30

Step-by-step explanation:

You will want to put the equation in the form y = mx + b where m is the slope and b is the y-intercept (an example is y = 2x - 1).

First, to find the slope you want to find how much x goes up by when y goes up by 1. You know from the table that when y goes up by 5, x goes up by -5 (using the points (10, 20) and (5, 25))

Then, you can divide each value by 5, so it would be when y goes up by 1, x goes up by -1. That means the slope is -1.

So far, the equation is y = -x + b. To find b, you can plug in one of the points you have and solve for b. For example, substitute in x = 10 and y = 20, so:

20 = -10 + b

add 10 to both sides

30 = b

So you know the equation is y = -x + 30

Please let me know if any parts of these explanation are confusing, I definitely think this concept can be confusing at time. Good luck with your work! :)

Answer:

To create an equation, you need to find the slope first. The slope formula is [tex]\frac{y^2-y^1}{x^2-x^1}[/tex]. Let's use two random coordinates: (10,20) and (5,25). Plug in these digits into the formula to get [tex]\frac{25-20}{5-10}[/tex]. Simplify to get [tex]\frac{5}{-5}[/tex] or -1. The equation would look like y=-x+b. Now we need to find b. Again, let's use a random coordinate: (10,20). Plug in the digits into the variables to get 20=-10+b. Add 10 on both sides to get 30=b. So, the equation would be y=-x+30.
