Step-by-step explanation:
Given:
After a storm damages the community center, Shanika and her friends hold fundraising.
After the first event, they raise $240, which is 10% of the total amount that they want to raise.
Now, to find the total amount of money that Shanika and her friends want to raise.
Let the total amount of money that Shanika and her friends want to raise be 
.
As given 10% of fundraise is $240.
So, according to question:
<em>Multiplying both sides by 100 we get:</em>
<em>Dividing both sides by 10 we get:</em>
Therefore, the total amount of money Shanika and her friends want to raise is $2400.
Answer:
0.67 cm/s
Step-by-step explanation:
The area of a square is given by :
....(1)
Where
x is the side of a square
Differentiating equation (1) wrt t.
When A = 81cm², the side of the square, x = 9 cm
Put all the values,
So, the length of the side of a square is changing at the rate of 0.67 cm/s.
2(2x-4) because when you multiply 2 x 2x it equals 4x. When you multiply 2 x 4 it equals 8. Leaving you with 4x-8
Answer:
A cylinder with a volume of 27
cubic inches and a height of 3 inches
Step-by-step explanation:
- Volume of a cylinder = r²h
(where r is the radius and h is the height)
Volume = 27
Height = 3
⇒ 27 = 3r²
⇒ 9 = r²
⇒ r = √9 = 3
So height = radius
Answer:
The answer is (x + 3) (x - 7) = 0
Step-by-step explanation:
x² - 4x = 21
x² - 4x - 21 = 0
x² - 7x + 3x - 21 = 0
x(x - 7) + 3(x - 7) = 0
(x + 3) (x - 7) = 0
Thus, The answer is (x + 3) (x - 7) = 0
