The ratio of blue marbles to red marbles in a box is 3 to 2. if there are 12 blue marbles in a box then how many red marbles are there?
Answer:
8 red marbles.
Step-by-step explanation:
The ratio is 3:2, blue to red. If there's 12 blue marbles and the first part of the ratio's 3, then:
12/3=4
Then you take the 4 and multiply it by 2, the second half of the ration to get 8.
And so, the answer's 8. If you divide 12:8 by 4 each you get your original ratio of 3:2, so that's your way to check.

Mrs. Garcia’s students were asked to find 220% of 75. Each of the students had a different method.
Amy: “I multiplied 2.20 by 75 to find my answer.”
Braden: “I created a table with columns for 100%, 100%, 20%, and 220%. Then I filled in the table and added the values.”
Colton: “I created a table with columns for 100%, 10%, 10%, and 220%. Then I filled in
the table and added the values.”
Danielle: “I divided 75 by 5 to find 20%. Then I added 75 twice to what I found to get my final answer.”
If all of the students completed their steps accurately, which student got the answer wrong?
Answer:
Colten took test reveiw on edge!
Step-by-step explanation:
Colton got the wrong answer
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
Garcia’s students were asked to find 220% of 75, we need to find who did incorrect answer among Amy, Braden, Colton and Danielle
Amy multiplied 2.20 by 75 to find my answer.”
220/100×75=2.2
His answer is correct
Barden
Braden created table for 100, 100 and 20% and added. This will be equivalent to finding 220%
Braden is correct.
Colton created table for 100%, 10% and 10% percent and added these.
But this addition would result in 100+10+10 =120% not 220%
Hence Colton is wrong.
Danielle divided 75 by 5 to find 20%.
Then he added 75 twice to find his answer.
Danielle is correct.
Hence Colton got the wrong answer

Given that a group of adults and students buy tickets for a dance performance.
The cost of each ticket is $4.65.
The total cost of the tickets for the group is $93.00.
There are exactly 3 adults in the group
We need to find the number of students in the group.
Let x be the number of students.
3(4.65)+4.65x=93
13.95+4.65x=93
Subtract 13.95 on both sides
4.65x=93-13.95
4.65x=79.05
Divide both sides by 4.65
x=17
Hence, the number of students in the group are 17.

Luke was out of cereal for breakfast. He walked to the grocery store to buy his favorite, Honey Nut Cheerios. While looking at the cereal, he noticed all the different box sizes and different prices. A giant "Family Size" box contained 14.7 oz and cost $5.99. A small, individual size contained 1.5 oz and cost $1.89. He wanted to get the most "bang for his buck." Which choice is the better buy? In other words, which choice is cheaper per ounce? Which one should he buy and why?
Answer:
The answer is the family size
Step-by-step explanation:
I had to find how much it is per ounce and for the small box it cost $1.25 per ounce and for the family size it cost $0.41 which is less than $1.25 so the answer would be the family size of Honey Nut Cheerios

Sam will take four science tests this quarter. Her scores on three of the tests are shown below.
What does Sam need to score on the fourth test to ensure that she will have an average of 90% for all four tests?
Answer:
98%
Step-by-step explanation:
Test 1 - 83%
Test 2 - 91%
Test 3 - 88%
Test 4 - ?
If we use x to represent Test 4, we can create the following equation:
1/4 (83 + 91 + 88 + x) = 90
We find the average here by adding up the four test scores and dividing by 4.
Proceed to solve it:
1/4 (262 + x) = 90
262 + x = 360
x = 98
Therefore, Sam needs to get a 98% to have and average of 90% on all four tests.

An electrician needs 3 rolls of electrical wire to wire each room in a house. How many rooms can he wire with 3/4 of a roll of wire?
Answer:
He can wire
[tex] \frac{1}{4} [/tex]
of a room with 3/4 of a roll of wire.
Step-by-step explanation:
We can solve by using proportions.
Let's set it up.
[tex] \frac{3 \: rolls}{1 \: room} = \frac{ \frac{3}{4} \: of \: a \: roll}{x} [/tex]
We are now going to cross multiply. By cross-multiplting, you would get:
[tex] \frac{3}{4} = 3x[/tex]
You are now going to divide both numbers by 3 in order to get the x by itself.
[tex] \frac{ \frac{3}{4} }{3} = \frac{3x}{3} [/tex]
By dividing, you get:
[tex] \frac{1}{4} = x[/tex]
Therefore, the answer is 1/4.
The number of rooms he can wire with 3/4 of a roll of wire is 1/4.
What are proportions?Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.
Given that, an electrician needs 3 rolls of electrical wire to wire each room in a house.
Let the number of rooms he can wire with 3/4 of a roll of wire be x.
Now, the proportion is
[tex]\frac{3}{1}=\frac{\frac{3}{4} }{x}[/tex]
3x=3/4
x=1/4
Therefor, number of rooms he can wire is 1/4.

1. Find the lengths of the diagonals of rectangle QRST , Given that QS = 6X+3 and RT = 8X-1
2. If QR=9 , Find the length of TQ (Hint: There is a right angle in the Corner!)
Answer:
1. QS and RT= 15
2. Im not positive but I think it's TQ=18
Step-by-step explanation:
For question 1, you would do 6x+3=8x-1 and solve to get the result of x=2
Then you'd plug in 6 and get QS and RT=15
For the second one I am unsure because I wasn't positive how to solve but it seems like the side RQ might be 1/2 of TQ. Sorry if thats wrong I can try and help more if you need
