2. find out how many of the marbles are blue and put it into a fraction blue/total number of marbles. e.g.(8/20)
3.multiply the fraction so that you have 100 as your denominator since 'per-cent' means out of 100. e.g.(8/20 x 5= 40/100)

A store paid $450 for a tablet and marked up the price to sell for $500. What is the percent increase?
please answer quickly!
Answers
Answer:
11.1111%
Step-by-step explanation:
markup = profit/cost * 100
Explanation: if you use the formula in the pic I’ve provided below, you can find the increase by first subtracting the old value (450) by the the new value which would be (500-450). Then, you divide the answer you got (50) by the old value once again, and you would get (50/450 = 0.11 *rounded) and 0.11 as a percent is 11%, so the percent increase it 11%.

A number has only 1 factor pair. One of its factors is twice the other factor. What is the number? Explain.
Please help me with this question. I will give brainliest ONLY if two people answer. Plz and thx :D
Answers
========================================================
Explanation:
If a number only has one factor pair, then that number must be prime. This is because prime numbers only have factors of 1 and the number itself.
For instance, the value 7 is prime because the only factors of this are 1 and 7.
For something like the number 32, it is composite and not prime because it has the factors {1,2,4,8,16,32} and it leads to these three factor pairs: 1*32, 2*16, 4*8. This is one example showing why the answer isn't composite.
-----------
Let's say that p is the unknown prime we want to find. The factors of this are 1 and p. We're told that "one of the factors is twice the other factor", so that must mean p = 2*1 = 2. We can see that 2 is twice that of 1.

what is the solution to -6x+y=-34 and
x+y=-1
Answers
Answer:
1. x = 1/6(y) + 17/3
2. x=−y−1
Step-by-step explanation:
1. Let's solve for x.
−6x+y=−34
Step 1: Add -y to both sides.
−6x+y+−y=−34+−y
−6x=−y−34
Step 2: Divide both sides by -6.
−6x/−6=−y−34/−6
x=1/6y+17/3
2. Let's solve for x.
x+y=−1
Step 1: Add -y to both sides.
x+y+−y=−1+−y
x=−y−1

Find the perimeter of the figure to the nearest hundredth. Sorry to ask ANOTHER question on this stuff but I'm doing an assignment and I don't get it-
Answers
Answer:
I did my best, but it has been a while. I really hope that this helps
Step-by-step explanation:
so you can find the perimeter of a circle
-----The perimeter of a circle is π × d where d is the diameter so half of that is 1/2 π × d. But If you are going to walk around a semicircle, you need to go halfway around the circle and then across a diagonal to get back to where you started, so the perimeter is 1/2 π × d + d.
