Answer:
4/3 pi≈3
Step-by-step explanation:
40/360 = 1/9
S= pi*r²* n/360
S= 3*4*1 /9 = 4/3
Answer:
Size of groups known: First and last questions (The rice and cups ones)
Number of groups known: Second and third questions (Cars and hats)
Step-by-step explanation:
In the first problem, you know that one sack is one group, and it tells you that each sack weighs 3 kg. Therefore, you know the size of the group (or a sack).
In the last one, you know that a table is one group and each table fits 4 cups. So, you know that the size of the group is 4 cups.
In the second and third questions, you know that each group is a row (cars) or "equal group" (hat) and that there are 4 of each. So, you know that there are 4 of each group, meaning you know the "number of groups"
Answer:
Step-by-step explanation: The answer is 6 friends. Assuming that the group is going in one car. Leaving them with 100.5 to spend on admission.You can add the admission fee 6 times until they have nothing left
Answer:
1) -43 2)-10
Step-by-step explanation:
so for the first one you would enter -9 into all of the x's
g(x)=4x-7
g(-9)=4(-9)-7 ( you would get -36, then you would minus y. so the answer is -43!)
g(-9)=-43
second one would be the same thing
g(x)=x^2-4x+11
g(-4)=-7^2-4(-7)+11
g(-4)=-10
