75=3w^2
sdivide by 3
25=w^2
square root
5=width
subsitute
3w=l
3 times 5=l
l=15

width=5

Answer:

  2.1 ft³

Step-by-step explanation:

Put the given radius and height into the volume formula and do the arithmetic.

  V = 1/3πr²h

  V = 1/3(3.14159)(1 ft)²(2 ft) ≈ 2.094 ft³

Rounded to tenths, this is 2.1 cubic feet.

__

The picture cuts off your rounding requirements. If it is hundredths, you need to use 2.09 ft³. If it is thousandths, your answer will depend on the value of pi you are asked to use.

I took a picture of a math question.
Maurinko [17]
A) One tenth is equal to 0.1, so you do 830,000 x 0.1 to get 83,000 people.  You can also do 830,000 divided by 10 to get the same answer since it is one-tenth.

B) You can divide 5280 by 4 to find the answer of this one.

C) Divide by 4 again (because it is a fourth), but then multiply by three because the question asks for three-fourths.

D) A minute is 60 seconds, so 60 divided by 3 is 20.  Given that it asks for two-thirds, you then multiple 20 by 2 to get the final answer of 40 seconds.

E) There are 24 hours in a day, so divide 24 by 8.

Hopefully this helps "get the ball rolling" for you!

What is the answer answer and plz give me step by step explaining
Tamiku [17]

Answer:

x = 5

Step-by-step explanation:

6 + 8(x - 1) = 2(3x + 4)

We evaluate the numbers in the brackets first.

(8 × x = 8x, 8 × 1 = 8, 2 × 3x = 6x, 2 × 4 = 8)

6 + 8x - 8 = 6x + 8

The left hand side of the equation is not exactly simplified, so we will evaluate it further first.

(6 - 8 = -2)

8x - 2 = 6x + 8

Now we can start shifting the x and the numbers separately.

Note that when pushing 6x from the right side to the left side, it needs to change to a negative 6x and vice versa for -2 turning into +2.

8x - 6x = 8 + 2

Further evaluation

2x = 10

Now we can simply find x.

Note that for this, ×2 becomes ÷2 when it shifts from the left side to the right side of the equation.

x = 10 ÷ 2

Evaluate.

x = 5

What is the area of a circle with a circumference of 36.68 units
Lina20 [59]

Answer:

radius = circumference / (2 * PI)

radius = 5.8378033126

Circle Area = PI * radius^2

Circle Area = PI * 5.8378033126^2

Circle Area = PI * 34.0799475167

Circle Area = 107.07 square units
