Answer:
The zoo will cost more money for a group of 12 students to visit.
Step-by-step explanation:
First, you have to divide the costs by the amount of tickets to find out how much you would have to pay for one ticket.
Science Center: $36.76 ÷ 3 = $12.25
Zoo: $51 ÷ 4 = $12.75
Then, the cost for one ticket should be multiplied by 12, the group of students wanting to visit.
Science Center: $12.25 x 12 = $147.04
Zoo: $12.75 x 12 = $153
Comparing the prices, you will see that the zoo will cost $5.96 more dollars than the science center.
Answer:
Step-by-step explanation:
if i can draw, then i can explain better
distance between centers=r+3r=4r
we have to find the side of a right angled triangle by pythagoras theorem
given hypotenuse=4r
and one side=3r-r=2r
this is the distance if they touch.
but if they are r distance apart
then distance between centers=r+r+3r=5r
so hypotenuse=5r
length of tangent
Answer:
He multiplied the radius by 2 instead of squaring it
Answer:
Step-by-step explanation:
Let's break it down. There is..
-----------------------------------------------------
A square root of a number: (assuming "the number" is ).
And they say that 9 is less than that, so we subtract 9 from , which gives us .
I hope that helps! :)
