Answer:5 people were in each car.
Step-by-step explanation:
Let x represent the number of people that travelled in each car.
The total number of people in the Bailey family that made the trip to the drive-in movie theater was 42.
Seven cars filled and 7 more people traveled in a truck. This means that
7x + 7 = 42
Subtracting 7 from the left hand side and the right hand side of the equation. It becomes
7x + 7 - 7 = 42 - 7
7x = 35
Dividing the left hand side and the right hand side of the equation by 7, it becomes
7x/7 = 35/7
x = 5
68
Schools almost over, good luck!!
Circumference is given by
C=2πr
From the information:
r=20 in
thus
C=2×π×20
C=40π inches
Answer:
the answer is 8
Step-by-step explanation:
Use the geometric mean involving altitudes. That will be
. Filling in our values for the legs of that triangle our proportion then looks like this:
. Cross multiply to get
. Taking the principle value of that square root, we get that x = 12.
