Answer:

99 cm2

Step-by-step explanation:

<u>1. to break this up a bit first find the area of the base</u>

10*2 = 20

<u>2. now 2 triangular sides with the base of 2</u>

2*8/2= 8 (each triangle is 8 cm2)

there's two of them so it's 16

<u>3. now the last two triangular sides</u>

10*6.3/2=31.5

there's two of them so it's 63

<u>4. add it all up: 20 + 16 + 63 =99</u>

A company has made a rubber ball for $0. 02 per square foot. The company wants to spend a maximum of $1 each on a new ball.
Misha Larkins [42]

The diameter of the new rubber ball, to the nearest foot, must be D =  4.0 ft (in the case of the maximum cost).

<h3>How to find the diameter of the ball?</h3>

Remember that for a sphere of diameter D, the surface area is:

A = 4*pi*(D/2)^2

In this case, the cost is $0.02 per square foot, and the company wants to expend (at maximum) $1 per ball, so first we need to solve:

$0.02*A = $1

A = $1/$0.02 = 50

So the surface of the ball must be 50 square feet.

Then we solve:

50ft^2 = 4*3.14*(D/2)^2

D = 2*√(50 ft^2/(4*3.14)) = 4.0 ft

The perimeter of a regular pentagon is represented by the expression 35d-25. Daryl correctly wrote expression to represent the o
Triss [41]

Answer:

Each one of the sides is equal to 7d-5

Step-by-step explanation:

A regular pentagon has 5 sides of equal length.

The perimeter of a regular pentagon is given by

P = 5s where s is the side length

35d -25 = 5s

Divide each side by 5

(35d-25)/5 = 5s/5

7d-5 =s

Each one of the sides is equal to 7d-5
