A busy customer service agent handled 20 emails in 1/4 of a day. At that rate, how many emails could he handle in 1 day?
Step-by-step explanation:
20 mails in 1/4 day (0.25 day)
-> 1 day = 20/0.25 = 80 emails
A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
1/4 day = 20 emails
1 day = 80 emails
The number of emails he could handle in a day is 80 emails.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example:
1/2, 1/3 is a fraction.
4/8 = 1/2 is a fraction
6/8 = 3/4 is a fraction.
We have,
The number of emails handled in 1/4 of a day = 20 emails.
This can be written as,
1/4 day = 20 emails
Multiply 4 on both sides.
4 x 1/4 day = 4 x 20 emails
1 day = 80 emails
Thus,
1/4 day = 20 emails
1 day = 80 emails
The number of emails he could handle in a day is 80 emails.

find the difference between the first and second hour earnings to get 10.
get the difference of the second and third to get 12.
we realize that they are in increasing with even numbers from 10 going further, ie, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28....etc
to get the total earnings for the 24 hrs, you have to keep on adding the next even number till you reach the 24th hour
you will get $786.

A cube has a side length of inch. It would take blocks with a side length of inch to fill the cube. It would take blocks with a side length of inch to fill the cube.
Complete question:
A cube has a side length of 1/3 inch.It would take _ blocks with a side length of 1/6 inch to fill the cube.
B)It would take _ blocks with a side length of 1/9 inch to fill the cube.
Answer:
a) 8 blocks
b) 27 blocks
Step-by-step explanation:
Here we need to find the volume of the cube and volume of the block.
To find volume of the cube, let's use the formula :
V = a³
Here a = [tex] \frac{1}{3}[/tex]
Therefore,
V = [tex] (\frac{1}{3})^3[/tex]
V = = [tex] \frac{1}{27}[/tex]
Volume of the cube is [tex] \frac{1}{27}[/tex]
To find volume of the block, let's use the formula:
V = a³
V = [tex] (\frac{1}{6})^3[/tex]
V = [tex] \frac{1}{216} [/tex]
To find the number of blocks, let's divide the volume of block from the volume of cube.
Therefore,
= [tex]\frac{\frac{1}{27}}{\frac{1}{216}}[/tex]
[tex] = \frac{1}{27} * 216 [/tex]
= 8
It would take 8 blocks with a side length of 1/6 inch to fill the cube.
B) Here we also need to find the volume of the cube and volume of the block.
To find volume of the cube, let's use the formula :
V = a³
Here a = [tex] \frac{1}{3}[/tex]
Therefore,
V = [tex] (\frac{1}{3})^3[/tex]
V = = [tex] \frac{1}{27}[/tex]
Volume of the cube is [tex] \frac{1}{27}[/tex]
To find volume of the block, let's use the formula:
V = a³
V = [tex](\frac{1}{9})^3[/tex]
V = [tex] \frac{1}{729} [/tex]
To find the number of blocks, let's divide the volume of block from the volume of cube.
Therefore,
= [tex] \frac{\frac{1}{27}}{\frac{1}{729}}[/tex]
[tex] = \frac{1}{27} * 729 [/tex]
= 27
It would take 27 blocks with a side length of 1/9 inch to fill the cube.

Find the area of this shape. The area of this shape is _______ square centimeters.
Answer:
Step-by-step explanation:
area =(4+4+4)/2×2+1/2×(4+4)×5.75
=12+23.00
=35 sq.cms.
Step-by-step explanation:
Area of triangle = [tex]\frac{1}{2}[/tex](b*h)
Area of rectangle = b*h
[tex]A(big-triangle) = \frac{1}{2} (5.75*4)[/tex]
[tex]A(big-triangle) = \frac{1}{2}(23)[/tex]
[tex]A(big-triangle) = 11.5[/tex]
Since there are two big triangles, then we can multiply 11.5 by 2.
11.5 * 2 = 23
[tex]A(small-triangle) = \frac{1}{2}(2*2)[/tex]
[tex]A(small-triangle) = \frac{1}{2} (4)[/tex]
[tex]A(small-triangle) = 2[/tex]
Since there are two small triangles, then we can multiply 2 by 2.
2 * 2 = 4
[tex]A(rectangle)= 4 * 2[/tex]
[tex]A(rectangle) = 8[/tex]
Now, we can add up all of the areas so we can find the total area of the entire shape.
23 + 4 + 8 = 35
So, the area of the entire shape is 35 square cm.
Each homeroom must send two student representatives to each student council meeting. Mrs. Lincoln has 15 girls and 10 boys in her homeroom. If she randomly selects two students to attend the next meeting, find the probability of her choosing one girl and one boy?
Answer:
1/4
Step-by-step explanation:
Mrs. Lincoln has 15 girls and 10 boys in her homeroom. She randomly selects two students. The total number of students is 25.
The probability of choosing one girl is:
15 / 25 = 3 / 5
Now, 24 students are left.
The probability of choosing one boy is:
10 / 24 = 5 / 12
Therefore, the probability of choosing one girl and one boy is:
3 / 5 * 5 / 12
= 3 / 12
= 1/4

In a recent election Corrine Brown received 13 comma 482 more votes than Bill Randall. If the total number of votes was 120 comma 306, find the number of votes for each candidate.
Corrine Brown received
how many votes?
Answer:
53,412 and 66,894
Step-by-step explanation:
In this question we have to assume the things
Let us assume
Bill randall be X
So, the Corrine Brown is X + 13,482 as the corrine brown received 13,482 more votes than the Bill Randall
And, the total number of votes is 120,306
Now the equation is
X + X + 13,482 = 120,306
2X + 13,482 = 120,306
2X = 106824
X = 53,412 i.e Bill randall
And, the corrine brown is
= 13,482 + 53,412
= 66,894
Mags is 2 years older than Vector. Which equation will
help you find Mags' age (m) if you know Vector's age (v)?
v = m + 2
m = V + 2
V-2=m
Answer:
m = v + 2
Step-by-step explanation:
Since Mags (m) is 2 years older than Vector (v)
You can use the equation V + 2 which is Vector's age + 2 years. Which would be equal to Mags' age.

Solving similar triangles can someone please answer help
Answer:
k=3
Step-by-step explanation:
Since we know for a fact, thanks to it being given in your question, that the triangles are similar, that means the lengths are proportionate.
Secondly, you should notice a trend between both shapes. ΔPQRs sides are half of ΔDEFs.
With that in mind, we can conclude that for side K, it's half of 6, so 3! :D

M = 3
....................
Answer:
m = 3
Step-by-step explanation:
10m = 10-5(m-7)
10m = -(5m-5×7)+10
10m = -(5m-35)+10
10m = -5m + 35 + 10
10m = -5m +45
15m = 45
15m/15 = 45/15
m = 3^2*5/3*5
m = 3^2-1
m = 3
There are 1300 students in a school. 48% of them are female. How many are male?
Answer:
676
Step-by-step explanation:
First find what 48 percent of 1300 is
1300*0.48=624
Then subtract the number of females from the total number of students.
1300 student -624 females=676 males.
Hope that's clear :)
Answer:
[tex]676[/tex]
Step-by-step explanation:
48 % of students are female. so first we have to fine the percentage of male.
[tex]48\% = female \\ 100\% - 48\% = 52\% \\ 52\% = male[/tex]
Now lets fine how many male students are there.
[tex]1300 \times \frac{52}{100} = 676[/tex]

A playhouse is in the shape of a regular octagonal pyramid with a side length of 3 feet an a slant height of 12 feet. The wood used to build the walls of the playhouse costs $3 per square foot. What is the cost of the wood for the walls of the playhouse?
Answer: We just did these problems in my math class today! Ok, so you need to find the lateral surface area, or the area of the faces/walls. The formula for triangles is
1/2 • base • height. Sub in the #s, it would be 1/2 • 6 • 12
1/2•72
36
So now we know the area of one of the faces is 36inches^2, we can multiply that by 4, which is 144. 144•3($)= $432. To sum things up, $432 is the cost to build the walls of the playhouse, and we are not adding in the base, because the base is not a face!

If 8x=4
What is 2+12x?
Answer:
8
Step-by-step explanation:
If 8x = 4, then you can solve for x by dividing both sides by 8. Therefore, x = 4/8 or 1/2.
Then to solve 2 + 12x you simply plug in 1/2 for x.
2 + 12x
2 + 12(1/2)
