Please help it’s a math question!!

Answer:

u = ±8

Step-by-step explanation:

Given:  u^2 = 64.

Solve for u by taking the square root of both sides AND putting the ' ± ' symbol in front of the right side:

√u² = ±√64, or u = ±8

Answer:

[tex]u=8,\ u=-8[/tex]

Step-by-step explanation:

u² = 64

[tex]u\² = 64\\\\[/tex]              <== you take the square root of both sides

[tex]\sqrt{u\²} = \±\sqrt{64} \\\\[/tex]

[tex]u= \±8\\\\[/tex]              <== (u = plus or minus 8)

[tex]u=8,\ u=-8\\[/tex]

Answer:

e

Step-by-step explanation:

We are attempting to find the circumference of the pool.

The radius is 10 feet.

We need to use the formula:

C = [tex]\pi[/tex]r²

C = (3.14)(10)(2)

C = (31.4)(2)

C = 62.8

The circumference of the pool is 62.8 feet.

Answer:

5.1,5.1072,5.207,5.27

Answer:

The equivalent fractions will be 2:5 ard 12:30.

Step-by-step explanation:

Equivalent fractions simply mean the fractions that are the same or equal.

Based on the information given, the ratios that are equivalent to 4:10 will be:

4/10 = 2/5

12/30 = 2/5

20/8 = 5/2

8/30 = 4/15

Therefore, the equivalent ratios will be 2:5 and 12:30.

Answer:

2 : 5 and 12 : 30

Step-by-step explanation:

you can find if two ratios are equivalent by multiplying or dividing both quantities by the same number.

Hence:

4 : 10 x 3 on both sides = 12 : 30

Also

4 : 10 divided by 2 on both sides = 2 : 5

Making these equivalent

The others don’t qualify since for:

8 : 30

You would have to multiply the 4 in 4 : 10 by 2, and the 10 by 3, so basically it can’t work.

For 20 : 8

You would have to multiply the 4 in 4 : 10 by 5 and yet divide the 10 by 1.25 which definitely doesn’t work because a, the number used to multiply/divide is the same, and b, because both sides have to be multiplied or divided, not just one each.

Answer

x=15.8

Step-by-step explanation:

20.3*2=40.6

72.2-40.6=31.6

31.6/2=15.8

(15.8*2)+(20.3*2)=72.2

20.3*2+x*2=72.2

x=15.8

Step-by-step explanation:

Jada makes sparking juice by mixing 2 cups of sparkling water with every 3 cups of apple juice.How much sparkling water does Jada need if she uses 15 cups of apple juice?

Answer = 10

Explanation:

Ratio for mixing 2 cups of sparkling water with every 3 cups of apple juice

2 : 3

Thus also means:

2/3 = x/15

Solve for x:

x = 10

-------------------------------------------------------------------------------------------------------------

How much apple juice does Jada need if she uses 6 cups of sparkling water?

Answer = 9

Ratio for mixing 2 cups of sparkling water with every 3 cups of apple juice

2:3

Also means:

2/3 = 6/x

Solve for x

x = 9

-------------------------------------------------------------------------------------------------------------

Let S represent the number of cups of sparkling water and J represent the number of cups of apple juice. Write an equation that shows how S and J are related. Use your answers from the previous question to assist you with your answer.

Answer =  j = 3/2 ⋅ s

Answer:

a.  the relationships between the area of walls left to paint and the time they have been working

b. Company 1

c. Company 2

d. Company 1 = 147 hours, company 2 = 162 hours

Step-by-step explanation:

a. The linear functions model the relationships between the area of walls left to paint and the time they have been working.

b. Company 1 is painting faster because the first line has a slope of -1000/7 while the second line has a slope of -100/9, which means Company 1 is painting 100 ft^2 every 7 hours while Company 2 is painting 100 ft^2 every 9 hours. Therefore Company 1 is going faster.

c. Company 2 had less area to paint when they began because at the 0 hour mark, company 1 had 2100 ft^2 to paint and company 2 had 1800 ft^2 to paint.

d. Company 1 will take 21*7=147 hours to finish. Company 2 will take 18*9=162 hours to finish.

Answer:

13.1926121372

Step-by-step explanation:

Use a calculator

solution = 4 ?

6 * 4 - 3 = 24 - 3 = 21 not 45 so 4 is not the solution

the solution = 8

6 * 8 - 3 = 48 - 8 = 45

Answer:

8

Step-by-step explanation:

Let us first sole the equation for x.

6x - 3 = 45

-> 6x = 45 + 3

-> 6x = 48

-> x = 48/6

-> x = 8

Thus 8 from the set {4, 5, 6, 7, 8} makes the equation 6x - 3 = 45 true.

Answer:

  (b)  2 32/48

Step-by-step explanation:

You want the value of the expression 8 4/8 -5 5/6.

The difference of the mixed numbers can be found as the sum of the differences of the integer parts and fractional parts.

  (8 4/8) -(5 5/6) = (8 -5) +(4/8 -5/6)

  = 3 + ((24 -40)/48) = 3 - 16/48

  = 2 +(48/48 -16/48) . . . . . . . rewrite 3 to give a positive fraction part

  = 2 32/48 . . . . matches the 2nd choice
