Answer: 228.01 pi and the second is near 715. 9514

Step-by-step explanation: area of a circle is pi times the radius squared. Radius is half a diameter. Half of 30.2 is 15.1. 15.1 squared is 228.01. If you use 3.14 in place of pi, and multiply that to 228.01 you get 715.9514. I think

Which function represents a proportional relationship? A) f(x) = 3x 4 B) f(x) = 3 4x C) f(x) = 3x 4 + 3 4 D) f(x) = 3 4x + 3 4
densk [106]

Answer: OPTION B

Step-by-step explanation:

The equation of a line that passes through the origin is the following:

y=mx

Where "m" is the slope of the line.

By definition, Proportional relationships have the following form:

y=kx

Where "k" is the Constant of proportionality.

Then, as you can notice, if you graph a Proportional relationship you will get a line that passes through the origin.

Therefore, based on the explained above, you can conclude that the option that shows a function  that represents a Proportional relationship is the Option B.

Then, this is:

f(x)=\frac{3}{4}x

REAL LIFE A cylindrical hazardous waste container has a diameter of 1.5 feet and a height of 1.6 feet. Abo
aivan3 [116]

Answer:

It can hold up to 1.256ft^3 of waste

<em></em>

Step-by-step explanation:

Given

D = 1.5ft -- Diameter

h = 1.6ft -- height

Required

Determine the amount of waste it can hold

This simply means that we calculate the volume of the cylindrical container.

And this is calculated using:

Volume = \pi r^2h

Where

\pi = 3.14

and

r = \frac{D}{2}

r = \frac{1.5}{2}

r = 0.75

So, we have:

Volume = 3.14 * 0.5^2 * 1.6

Volume = 1.256ft^3

<em>Hence, it can hold up to </em>1.256ft^3<em> of waste</em>

2(1 − x) = 9(1 + 2x) + 52(1 − x) = 9(1 + 2x) + 5
marusya05 [52]

Solving the equation 2(1-x) = 9(1 + 2x) + 5 we get x=-\frac{3}{5}

Step-by-step explanation:

We need to solve the equation 2(1-x) = 9(1 + 2x) + 5 and find value of x

Solving:

2(1-x) = 9(1 + 2x) + 5\\2-2x=9+18x+5\\Adding\,\,-18x\,\,on\,\,both\,\,sides:\\2-2x-18x=9+5\\Adding\,\,-2\,\,on\,\,both\,\,sides\\-20x=14-2\\-20x=12\\x=\frac{12}{-20}\\x=-\frac{3}{5}

So, solving the equation 2(1-x) = 9(1 + 2x) + 5 we get x=-\frac{3}{5}
