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.

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

So let us simplify that we have 30 x 100 divided by 40 by 100. So that will just be 30 by 40 which is equal to three x 4 and three x 4 is equal to 0.75, which also means 75%. So the probability that a student like chocolate ice cream, given that they like strawberry ice cream, movies 75%.

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]

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.

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

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.

15 is 20% of what number?
A.3
B.12
C.30
D.75
Answer:
D.75 is the answer
Step-by-step explanation:
We already have our first value 15 and the second value 20. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
STEP 115 = 20% × Y
STEP 215 =
20
100
× Y
Multiplying both sides by 100 and dividing both sides of the equation by 20 we will arrive at:
STEP 3Y = 15 ×
100
20
STEP 4Y = 15 × 100 ÷ 20
STEP 5Y = 75
Finally, we have found the value of Y which is 75 and that is our answer.
You can easily calculate 15 is 20 percent of what number by using any regular calculator, simply enter 15 × 100 ÷ 20 and you will get your answer which is 75
Answer:
75
Step-by-step explanation:
15 is 20% of What Number?
15 is 20% of What Number? - 15 is 20% of 75. 100% of 75 is 75, therefore 20 percent of 75 equals 15. To learn how to solve 15 is 20 percent of what number, see the step by step instructions below.
15 is 20 Percent of What Number?
75
Formula = Number x 100
Percent = 15 x 100
20 = 75
Following shows the steps on how to derive this formula and find out 20% of what number is 15.
Step 1: If 20% of a number is 15, then what is 100% of that number? Setup the equation.
15
20% = Y
100%
Step 2: Solve for Y
Using cross multiplication of two fractions, we get
20Y = 15 x 100
20Y = 1500
Y = 1500
100 = 75
