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.

Let p = number of pounds of candy Lena will buy
Given:
Candy = $5 per poundLena will spend less than $40Create an inequality using the given information:
⇒ 5p < 40
Solve the inequality:
⇒ 5p < 40
Divide both sides by 5
⇒ p < 8
Frank left his house at 7 a.m. and drove to the airport at
a speed of 50 mph. Lance left his house at 6 a.m. and
drove to the same airport at a speed of 55 mph. Frank's
house is 150 miles from the airport and Lance's house
is 220 miles from the airport.
At what time did Lance arrive at the airport?
Answer:
10 AM
Step-by-step explanation:
Frank drove at a speed of 50 mph, and traveled a distance of 150 miles. This means he traveled for 150/50 = 3 hours. 7 AM + 3 hours = 10 AM
Find the interest on $4,000 at 3% for 4 months.
$480
$40
$400
$48
Answer:
$40
Step-by-step explanation:
everyone else on brainly agrees that $40 is the answerhave a great day :)))The number a is less than the number b by 1/5 of b. By what part of a is b greater than a? Need help ASAP. Have to get this done in 20 minutes.
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.
Alex has cards with different shapes on them. He sorts the cards and determines that 4% of the shapes on the cards are triangles. Alex has 5 triangle cards.
how many cards are there in all.
Answer:
125 cards
Step-by-step explanation:
I did this by dividing 100 by 4, since there is 100 percent in total. This gets 25. I then multiplied 25 by 5, because 4 percent = 5 cards. Basically for every 4 percent for every five cards. take it as the amount of 4 percents, there are the same amount of 5 cards.
Hope this helps :)

Find the interquartile range (IQR) of your data. Show your work.
23, 75,79,99,105,110,110,142,149,168,168,170,183,195,202
Please help I don't understand!
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

What is the value of x?
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:
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.

A lifeguard fills a pool with water at a constant rate. After 1/2 hour, 1/3 of the pool is filled.
At this rate, what fraction of the pool is filled per hour?
Answer: 2/3 of an hour.
Step-by-step explanation: The constant rate of the lifeguard filling the pool is 1/3 of the pool every 1/2 hour. If she fills it for an hour, she'll get 2/3 of the pool filled. Therefore, it'll take the lifeguard 1 hour to fill the pool 2/3 of the way.
