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.

I hope these solutions were helpful. Happy mathing!

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]

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:

Interquartile Range =  71

Step-by-step explanation:

The interquartile range is the middle 50% of the data set. First you calculate the location of the 3rd quartile (75% of the data set) by computing:

LQ3 = (75/100)(n + 1) -> here n is the number of observations you have, so 15. You can now compute LQ3 = (75/100)(16) = 12

The data at location 12 of your data set is 170.

Now you compute the 1st quartile (25% of the data set):

LQ1 = (25/100)(16) = 4

The data at location 4 of your data set is 99.

The difference between the 3rd quartile (170) and the 1st quartile (99) is your interquartile range:

IQR = 170 - 99 = 71

Answer:

4 problems

Step-by-step explanation:

(I'm going to type a lot, but it isn't at all hard when you really understand and get the hang of it) If you are assigned 32 math exercises for homework and you complete 87.5% of them, this means that the problem is not asking for 87.5 % of 32, but what is left after you finish 87.5%, which means we should subtract 87.5 from 100. 100-87.5=12.5. 12.5% now represents the percent of the 32 original questions we have left to do after dinner. So, now we need to create a proportion. 12.5% means 12.5% out of 100%, with the 100% meaning 32, because that is the total amount of questions we have. so, this means we have [tex]\frac{12.5}{100}[/tex]. To use this to solve our problem, we have to act as if the 32 also represents 100%. So, we have to multiply this fraction ([tex]\frac{12.5}{100}[/tex]) by [tex]\frac{x}{32}[/tex] so that the 12.5% out of 100 lets us see how many problems 12.5% out of 100% would represents the remaining questions out of 32. so, we would solve for x (x representing the questions left to do after dinner.) So, we would form this equation and solve for x. -->[tex]\frac{12.5}{100} =\frac{x}{32}[/tex]. Now, we would cross multiply, then divide. So we would first multiply 12.5 times 32. This would give us 400. Then, we divide 400 by the 100, which gives us 4, which means that we have 4 problems left to do after dinner.

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:

The number b is bigger than the number a by 1/4 of a.

Step-by-step explanation:

If the number a is smaller than the number b by 1/5 of b, then

a + 1/5b = b.

Thus,

a= b - 1/5b= 4/5,

b= 5/4 a.

Consider the Expression b=5/4a:

b=5/4a= 4/4a+ 1/4a= a +1/4a

This gives that the number b is bigger than the number a by 1/4 of a.

Answer:

x = 10

Step-by-step explanation:

the two angles shown are supplementary, they add up to 180 degrees

so we can write this equation to solve for 'x':

100 + 9x - 10 = 180

90 + 9x = 180

9x = 90

x = 10

Answer:

[tex]\tt x=10^o[/tex]

Step-by-step explanation:

The given angles are supplementary angles, meaning they add up to 180°.

[tex]\tt 100+ 9x - 10 = 180^o[/tex]

[tex]\tt 90 + 9x = 180^o[/tex]

[tex]\tt 90+9x-90=180-90\:\: (Subtract)[/tex]

[tex]\tt 9x=90[/tex]

[tex]\tt \cfrac{9x}{9}=\cfrac{90}{9}\;\;(Divide)[/tex]

[tex]\tt x=10^o[/tex]

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

Answer:

5 = |-5|

Step-by-step explanation:

Think of it as a number line, like in the picture below. The absolute value is how far a number is from zero (0). If 5 is 5 away from zero, then the opposite of 5 (-5) is also 5 away from zero.

Refer to the picture below for an illustration:

Answer:

Equal to.

Step-by-step explanation:

5 is the absolute value of -5. The bars you see indicate that you are trying to find the absolute value.

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

The absolute value is the distance of that number from 0. The absolute value is always positive.

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

|-5|= 5. If the bars were not there, then it would be [tex]5 > -5\\[/tex]. If the two terms were flipped, it would be [tex]-5 < 5[/tex]. But because the bars are there, it is resembling the absolute value.

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

Here are a few more examples to help you understand:

|6| The absolute value of 6 is 6. It is 6 values away from 0.

|-1| The absolute value of -1 is 1. It is 1 value away from 0.

|-10| The absolute value of -10 is 10. It is 10 values away from 0.

|98| The absolute value of 98 is 98. It is 98 values away from 0.

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