(See attached picture for the diagram of both fuel tanks)

Answer:

2ft

Step-by-step Explanation:

==> Given:

Two cylindrical fuel tanks, one has a radius of 3ft, and height of 8ft, the second tank has a radius of 6ft and unknown height.

Also, volume of 1st tank = volume of 2nd tank

==> Required:

Find h = unknown height of the the 2nd tank.

=>Solution:

To find the height of the 2nd tank = h, we need to know the volume. Thus, volume of first tank = volume of 2nd tank.

Since the dimensions of the 1st tank are all given, let's find its volume.

Thus, volume of 1st tank using the formula V = πr²h (where π = 3.14, r = 3ft, h = 8ft)

V = 3.14*3²*8

= 3.14*9*8 = 226.08 ft³

Volume of first tank = volume of 2nd tank = 226.08 ft³

=> Let's find the height of the 2nd tank with same volume of 226.08ft³

Therefore, V = πr²h (V = 226.08, r = 6ft, h = ?)

226.08 = 3.14*6²*h

226.08 = 3.14*36*h

226.08 = 113.04*h

226.08/113.04 = h

2 = h

Height of the second fuel tank (h) = 2ft

What is the result of isolating y2 in the equation below?
lyudmila [28]
STEP-BY-STEP SOLUTION:

( x + 4 )^2 + y^2 = 22

x^2 + 2 × x × 4 + 4^2 + y^2 = 22

x^2 + 8x + 16 + y^2 = 22

y^2 = 22 - x^2 - 8x - 16

y^2 = - x^2 - 8x + 6

FINAL ANSWER:

Therefore, the answer is:

D. y^2 = - x^2 - 8x + 6

What kind of function is being illustrated by f(x)=|2x³-3x|+5?
Dimas [21]

Answer:

Option D: Absolute value function

Step-by-step explanation:

The absolute value of a number is the distance of the number from 0 to the left or right on the number line.

We are given the function;

f(x) = |2x³ - 3x| + 5

This function contains an absolute value symbol which is |2x³ - 3x|.

This function is thus illustrated by an an absolute value function because an absolute value function will be one that contains algebraic expressions within absolute value symbols.

Answer:

50 combos

Step-by-step explanation:

Put it into an equation first in order to find x.

2x + 250 = 7x

Subtract 2x from both sides.

250 = 5x

Then divide both sides by 5.

x = 50

Therefore you need 50 combo meals in order to make the amount made equal to the amount paid.

<u>You can check your work by plugging in the number to both.</u>

$250 plus the $2 times 50 combo meals.

250 + 2(50) = 350

$7 times 50 combo meals

7 x 300 = 350
