Answer:

The surface area is 3140 feet².

What is Surface Area?

Surface area is the amount of space covering the outside of a three-dimensional shape.

Given that:

Diameter = 20 feet

radius =  20 ÷ 2 = 10 feet

Now, Surface area  will be,

=2πr²+ 2πrh

= 2 × 3.14 × (10)² + 2 × 3.14 × 10 × 40

= 6.28  × 100  + 6.28  × 400

= 628 + 25.12  × 100

= 628+ 2512

= 3140 feet²

hence, the surface area is 3140 feet².

Simplify the expression.
Kitty [74]
5(8x - 10) - 10x + 25(8x - 10) - 10x + 2
= (40x - 50) - 10x + (200x - 250) - 10x + 2
= 40x - 50 - 10x + 200x - 250 - 10x + 2
= (grouping like terms together)
= 40x - 10x + 200x - 10x - 50 - 250 + 2
= 220x - 298

Answer:

2.27%

Step-by-step explanation:

Lets start by making the names letters, J C and A respectively.

The total is 44 dollars. J paid 34%, which would be 14.96. He pays a total of $15. C paid 50%, which is 22 dollars. A pays 17%, which would be 7.48. She pays a total of $8.

15 + 8 + 22 = $45, meaning they paid an extra 1 dollar. One dollar is 1/44th of $44, or 2.27%.

Note: 2.27% is 2.272727272727 repeated, do what you will with that information, every site is different.

Looking to solve (Ac+b-d)(a^2-c)=
Sunny_sXe [5.5K]

It should be noted that the expansion of the equation (ac+b-d)(a² - c) will be a³c + ac² + a²b - bc - a²d + cd.

<h3>How to illustrate the information?</h3>

It should be noted that an equation is used to show the relationship that occur between the variables that are illustrated.

In this case, it should be noted that the equation

(ac+b-d)(a² - c) will be solved accordingly. This will be:

(ac+b-d)(a² - c)

Open the parentheses

a³c + ac² + a²b - bc - a²d + cd

Therefore, it should be noted that the expansion of the equation (ac+b-d)(a² - c) will be a³c + ac² + a²b - bc - a²d + cd.
