Answer:18

4x +108=180

Step-by-step explanation:

Answer:

x=18

Step-by-step explanation:

a straight angle is a total of 180 degrees so you subtract 108 from 180 to get 72 and then divide by 4 to get 18

Answer: The Answer is D.) 16/25

Step-by-step explanation: I got it correct on Study Island

surface area= perimeter x height + 2b

s= pxh+2b

example: 18(8)+2(12)

explain:  18 is the perimeter and 8 is the height then you have to add the base times 2

Answer: 338 Sq. Ft.

Step-by-step explanation:

26 is the identified length, half of 26 is 13 therefor 13 is the width. Length x Width gives you the area, 26 x 13 gives you 338 Sq. Ft.

Answer:

y = 0

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−5(6+7y)=−5(6+y)

(−5) (6) + (−5) (7y) = (−5) (6) + (−5) (y) (Distribute)

−30 + − 35y = −30 + −5y

−35y − 30 = −5y −30

Step 2: Add 5y to both sides.

−35y − 30 + 5y = −5y −30 + 5y

−30y −30 = −30

Step 3: Add 30 to both sides.

−30y − 30 + 30 = −30 + 30

−30y = 0

Step 4: Divide both sides by -30.

−30y /−30  =  0 /−30

2=b through the slope -2=-2(2)+b

Answer:

Your answer is 346.36059

Step-by-step explanation:

A = pi*r²

A = pi * 10.5²

A = pi * 110.25

A = 346.36059

We can write the the area of the circle as 110.25π square centimeter.

Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write -

V = ∫∫F(x, y) dx dy

Given is a circle whose diameter is 21 cm​.

It is asked to find the area of a circle whose diameter is 21 cm​.

It is given that the diameter of the circle is -

d = 21 cm

r = d/2 = 21/2

r = 10.5 cm

We know that the area of the circle as -

Area = πr²

Area = π x 10.5 x 10.5

Area = 110.25π

So, it can be concluded that the area of the circle is 110.25π square centimeter.

Therefore, we can write the the area of the circle as 110.25π square centimeter.

Answer:

  10

Step-by-step explanation:

The distance formula is useful.

  d = √((x2 -x1)^2 +(y2 -y1)^2)

  d = √((7 -1)^2 +(12 -4)^2) = √(6^2 +8^2) = √(36 +64) = √100

  d = 10

The distance between P and Q is 10.

Answer:

3a. yes

3b. y= 75x

3c. 600 mi

3d. 10 inches

Step-by-step explanation:

3a: if you divide the y by the x, you'd get 75 everytime, meaning it's proportional.

3b: y would equal the amount of inches multiplied by 75, so y=75x

3c: you can use the equation and substitute the x for 8, so y=75(8), giving you 600 miles

3d: you can also use the equation in reverse, if the actual miles is 750, then this is your y, so it would look like 750=75x and to solve you'd divide, 750/75, giving you 10 inches

C. 700 units.

The formula for the surface area of a rectangular prism is: 2 ((Width × Length) + (Height × Length) + (Height × Width))

(14 × 12) + (7 × 12) + (7 × 14)

168 + 84 + 98 = 350

Now do 350 × 2 = 700
