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.

u^2=64 solve using square root property

Answers

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]

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.

Learn more about fractions on:

brainly.com/question/2972832

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.

Step-by-step explanation:

Subtraction

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

Know he answer for this???

Answers

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:

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.

Kevin and Tiana are making soup. The recipe calls for a pound of onions. They have one onion that weighs ½ pound and another that weighs ⅖ pound. Kevin says they only have 3/7 pound of onions, so they definitely don’t have enough. Why is Kevin wrong?
PLSSSS HELP!

Answers

Kevin is wrong because adding fractions, you don’t add the numerator and the denominator on each one like you do when you are multiplying them, instead you have to find a common denominator, which is the lowest number that is a multiple of all of your denominators so in this case tej common denominator would be 10, so on the 2/5 fraction times the top and bottom by 2 so you get 4/10 and on the 1/2 fraction times the top and bottom by 5 to get 5/10 then you can add 4/10 and 5/10 to get 9/10 which cannot be simplified so Kevin and Tiana have 9/10 of a pound on onions
