Answer: 461.60 is the volume of liquid the tank can hold.
Step-by-step explanation:
We were given;
Height H = 9 ft
Diameter D = 14 ft
Pie π = 3.14
We will make use the formula of volume of a cone to get volume of water the tank can hold because it is said that the tank is in the shape of a cone
So
V = 1/3 * πr2h
First we need to find our radius r
Radius = 1/2 of diameter = 14/2 = 7
So using the formula
V = 1/3 * πr2h
V = 1/3 (3.14 * 7² * 9)
V = (3.14 * 49 * 9)/3
V = 1384.74 / 3
V = 461.58 = 461.60 (nearest ten)
Answer:
$3063.6
Step-by-step explanation:
72% of $4,255 = $3063.6
The formula for finding percents is number x percent ÷ 100.
4,255 x 72 ÷ 100 = 3063.6

♡ The Explanation/Step-By-Step ♡
-
6/100 + 5/100 + 80/100 + 9/100
Apply the fraction rule! --> a/c + b/c = a + b over c
6/100 + 5/100 + 80/100 + 9/100 = 6 + 5 + 80 + 9 over 100
Add the numbers: 6 + 5 + 80 + 9 = 100!
= 100/100 Apply the fraction rule! a/a = 1
a/a = 1 = 100/100 = 1

Answer:
x = 52
Step-by-step explanation:
To answer this question, we need to set up a system of linear equations:
x = 4y - 8
(1/2)x + y = 11 (Note: Please use ( ) around fractions such as this 1/2, to
eliminate possible ambiguity)
We want to find the x-coordinate, so should start by elilminating y from this system of equations.
Do this by multiplying the 2nd equation by -4. This results in
-2x - 4y = -44
Combine this result with x = 4y - 8:
x = 4y - 8
-2x - 4y = -44
----------------------
-x = -52 (Notice how the "y" terms cancel each other out.)
Dividing both sides by -1 produces the desired answer: x = 52
