Answer:
Step-by-step explanation:
If R, A, and P all share 108 pounds in the ratio of 2 to 3 to 1, then
2x + 3x + 1x = 108 and
6x = 108 so
x = 18.
R holds the ratio of 2x, so he gets 2(18) which is 36;
A holds the ratio of 3x, so he gets 3(18) which is 54;
P holds the ratio of 1x, so he gets 1(18) which is 18.
36 + 54 + 18 better equal 108...and it does!
I would say that this study is an experiment.
The car manufacturer wants to test some changes that he wants to implement in his cars, which is why he has two control groups (standard cars and cars with the new content) to test those changes out. This is a typical experiment and not an observation as he is not really observing much.
Answer:
The cost of 4 medium pizzas:
4 (x - 3)
Step-by-step explanation:
#3
x = the cost of a large pizza
medium pizza costs $3 less than a large pizza. So it's x - 3
If 4 medium pizzas then it will be: 4 (x - 3)
Hi There!
Donna needs to memorize words on a vocabulary list for Korean class. She has memorized 36 of the words, which is three-fourths of the list. How many words are on the list
36 / 3 = 12
12 * 4 = 48
There are 48 words on the list.
Hope This helps :)
Answer:
1. A=bh/2
2. I don’t know, I‘m sorry :(((( but if I had to guess I’d pick A = s x s
3. A = πr² (might be wrong, i’m so sorry)
Step-by-step explanation:
1. The formula for area of a triangle is A = bh/2
2. The formula for area of a square is s x s.
3. The formula for area of a circe is A = πr².
