You are assigned 32 math exercises for homework. You complete 87.5% of these before dinner. How many do you have left to do after dinner?
How Many problems Are left
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.

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.

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:
(b) 2 32/48
Step-by-step explanation:
You want the value of the expression 8 4/8 -5 5/6.
SubtractionThe 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:
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
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]

Write an equation to find the width of the frame, x.
Enter the correct equation in the box.
What is the equation
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.
