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

Answer : Add Both Together And You Get = 84

Brushes :  8 * 3 = 24

Paints : 10 * 6 = 60

Answer:

[1] 10

[2] 9

[3] j = 3/2 ⋅ s

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 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.

Answer:

∠M will be 147°

Step-by-step explanation:

Supplementary means adding up to 180° so take your 180° to subtract 33° from it and you'll have your answer.

Answer:

147

Explanation:

Supplementary angles all equal to 180, so that means that <M and <N must be both equal to 180.

If you want to find <M, you have to do 180 - 33, which equals to 147.

Answer:

3(trapezoid): 71.5

Right Triangle: 6.5

2(scalene triangle): 24

Step-by-step explanation:

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:

The area of the square would be 8

Step-by-step explanation:

It is shaded across 4 and down 2, so you would multiply 4 x 2 = 8

Answer:

Make a bell curve for the points 99, 60, 82, 78, 93, 71, 68, 86, 80, 95, 72, 64 · The variables x and y have a proportional relationship, and y=7 when x=2.

Answer:

[tex]\frac{8}{9}[/tex]

Step-by-step explanation:

So, there are 8 pieces with color and 1 piece without the wanted color.

The equation for finding the probability is:  [tex]\frac{sum of terms }{number of terms }[/tex]

Therefore: 3 + 5 = 8  and 9 pieces in total

so the correct answer should be 8/9

Answer:

1. Inconsistent

2.Inconsistent

3.Inconsistent

4.Consistent

5.Consistent

6.Consistent

Step-by-step explanation:

I tried my best , I’m not sure if these are correct through

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:

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]
