1,013 is what each restaurant would donate

947 + x = 683 + 5x

-683 -683

264 + x = 5x

- x -x

264 = 4x

Divide 264 by 4 = 66

Where r is the radius of the cylinder and h is the height of the cylinder.

AnnyKZ [126]

<h3>Given:-</h3>

radius = 7 inches
height = 9 inches

$\\ \\$

Surface area of cylinder

$\\ \\$

we know:-

$\bigstar \boxed{ \rm Surface \: Area \: of \: Cylinder=2\pi rh+2\pi {r}^{2} }$

$\\ \\$

So:-

⇢SA of cylinder=2πrh+2πr²

$\\$

⇢SA of cylinder = 2πr(h+r)

$\\$

⇢SA of cylinder = 2 × π × 7(7 + 9)

$\\$

⇢SA of cylinder = 2 × π × 7 (16)

$\\$

⇢SA of cylinder = 2 × π × 112

$\\$

⇢SA of cylinder = 2 × 112 × π

$\\$

⇢SA of cylinder = 224π inches ²

$\\$

.°. Surface Area of cylinder is 224π inches².

The sand used for sanding icy roads in the winter is stored in a conical-shaped structure with a radius of 10 m and a height of

pshichka [43]

Answer:

1,675.516

Step-by-step explanation:

The formula for a cone is V = pi r^2 h/3.

Plugging in the values of the radius and height, V = pi 10^2 16/3

Solving, you get:

V = pi 100 5.3333333

V = 1,675.516

Han is multiplying 10x4 by 0.5x3 and gets 5x7. He says that 0.5x3 in not a polynomial because 0.5 is not an integer. What is the

belka [17]

The coefficient does not determine whether a function is a polynomial or not but the degree of the polynomial.

Multiplying polynomial expressions

Given the following product of the polynomial as shown below

10x^4 * 0.5x^3

Multiply the decimal and the exponent to have;

10x^4 * 0.5x^3

(10*0.5) *(x^4 * x^3)

(10*1/2) * (x^4+3)
(5)x^7

Hence the product of the given polynomial function is 5x^7

The error in Han's thinking is by assuming 0.5x^3 is not a polynomial because 0.5 is not an integer. The coefficient does not determine whether a function is a polynomial or not but the degree of the polynomial.

Jeffrey went to the Outlets to buy some clothes. He bought a pair of pants for $59.99 and a nice shirt for $32.00. He read a sig

atroni [7]

Answer: 64.39 dollars

==========================================================

Explanation:

Before the discount, he would spend 59.99+32 = 91.99 dollars. This is before sales tax is added.

However, he gets 30% off, so he saves 0.30*91.99 = 27.597 = 27.60 dollars.

Meaning that he actually spends 91.99 - 27.60 = 64.39 dollars

--------------

As a shortcut, we can multiply 91.99 by 0.70 to get 64.393 which rounds to 64.39

The 0.70 is due to the fact that if he saves 30%, then he still has to pay the remaining 70%

Keep in mind that sales tax would need to be added on; however, your teacher doesn't mention the sales tax rate.
