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.

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

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]

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 student is saving at least $5,000 for college. She begins with a savings account set up by her parents containing $2,000. Each month she deposits an additional $50 into the account. Fill in the first blank with the correct expressions that make the statement true.
(Attached is the statement and the choices)
This is the first box only!! Pls help!!! Giving 15-20 points!!!
Answer:
5000 ≥ 2000 + 50a
Step-by-step explanation:
She wants to save at least $5000 for college. The saving account set up by her parents already contains $2000 . This means she has more $3000 to save to meet her minimum target. Each month she saves $50 into the account.
Let
number of month = a
The information can be expressed as follows
5000 ≥ 2000 + 50a
The savings will continue increasing every months because she always deposit $50 every month.
Using the expression
5000 ≥ 2000 + 50a
minus 2000 from both sides
3000 ≥ 50a
divide both sides by 50
3000/50 ≥ a
60 ≥ a
This means she needs at least 60 months to meet her savings/target.

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 mean and median and made of the following data 30,31,35,29,32,30,31,35,36,35
Answer:
Mean: 35
Median: 31
Mode: 36.9 (If you round up), 36.8 (If you don't round up)
Step-by-step explanation:
Order the Data: 29, 30, 30, 31, 31, 35, 35, 35, 36
Mean: Average , sum all of your data and divided by how many scores are in your data. (From Math Notes I have)
332/9 = 36.9 (If you round up)
Median: Middle Score (From Math Notes I have)
In this case the Median is 31.
Mode: The score that up most (From Math Notes I have)
In this case the Mode is 35.

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.
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

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

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!
