Answer:
60
Step-by-step explanation:
50+50+50+50+100= 300
divide by 5 students
300/5 = 60
When you graph the three lines, the first two overlap. The third is parallel to those two.
Step-by-step explanation:
13=blue blankets 7=red blankets
First, we need to know how many blankets there are in total.
13+7=20
Now, we don't need the seven anymore. Our ratio is blue blankets to total blankets.
13/20
Now, we need to know how many blue blankets there are in percentage.
13/20 = x/100
Next step: 13 times 100 is divided by 20
x= 13(100)÷20
x=1300÷20
x= 65
Therefore there are 65% of blue blankets.
Answer:
40
Step-by-step explanation:
SO im guessing if its the full graph one box counts 1.
So the top side counts 8
The left one is 15
The perimeter means adding all the sides together.
We already have 2. But finding the hypotenuse would not be easy from graph so we will use Pythagorean theorem.
a^2+b^2=c^2
8^2+15^2 = c^2
64+225 = c^2
289 = c^2
c = 17
so the perimeter is 8+15+17 = 40
