Answer:
≈101
Step-by-step explanation:
Let x and y represent the number of robberies in last year and this year respectively.
Given;
x = 147
This year the number of robberies has gone down 31%.
So;
y = x - 31% of x
y = x - 0.31x
y = 0.69x
Substituting the value;
y = 0.69 × 147
y = 101.43
y ≈ 101. (to the nearest whole number)
The number of robberies this year = 101
Answer:
192 children and 145 adults were admitted.
Step-by-step explanation:
Let c represent the amount of children and let a represent the amount of adults.
Total fees for children = (Fee for one child) x (Amount of children) = 6.5c
Total fees for adults = (Fee for one adult) x (Amount of adults) = 15a
Total fees = Total fees for children + Total fees for adults
3423 = 6.5c +15a
We know that the amount of people who entered the park was 337. Therefore a+c=337, which means a=337-c.
Sub this in to the equation above to get:
3423 = 6.5c +15 (337-c)
3423 = 6.5c + 5055 - 15c
-1632 = -8.5c
c = 192
So there were 192 children.
Since a=337-c and c=192, a=337-192=145. So there were 145 adults.
Answer:
C(0,2) - Not A Right Angle
C(3,-1) - Right Angle
C(0,4) - Right Angle
I took the unit test and after this was the correct and answer. Hope this helps :))

Answer:
5
Step-by-step explanation:
Katherine will use a multiple of 1/2 pint to serve her guests. That is the number of pints she will serve will be 2 1/2 = 5/2 = 5×(1/2).
Katherine can serve a maximum of 5 guests with the ice cream she purchased.

We could look at the quotient of 2 2/3 = 8/3 and 1/2. It will be ...
(8/3)÷(1/2) = (8/3)×(2/1) = 16/3 = 5 1/3
The largest whole number in this value is 5, the number of guests Katherine can serve.
