Given:
Admission to the local movie theater is $3 for each child and $7 for each adult.
A group of 12 people pay $64 admission.
To find:
The number of children in a group.
Solution:
Let the number of children be x and number of adults be y.
According to the question,
Total persons : ...(i)
Total cost : ...(ii)
Multiply equation (i) by 7 and subtract the result from (ii).
Divide both sides by -4.
Therefore, the number of children is 5.
16/3= 5 and 1/3
16* 5 and 1/3
=3, so 3 are not baseball players ,which means that 13 are
answer:13
58,000 people / 22 mi^2 = 2636.36 people per mi^2
There are 91 cupcakes and you sold boxes containing 13 cupcakes so you sold 7 boxes.
91 / 13 = 7
7 X 15 = $105
Answer:
Step-by-step explanation:
Given,
r=3
arc=3/2*pi
we know that,arc=theta(angle)*2*Pi*r/360
theta*2*pi*3/360=3*pi/2
pi and 3 cancel on both sides
theta*2/360=1/2
theta/180=2
theta=180/2
Hence theta or the angle required=90 degrees(option C)
