Answer:
Step-by-step explanation:
Since the boys collected 16 cans each and there are 12 of them it means they collected 16*12= 192 cans in total
there are 15 girls and each collected 14 cans. Therefore they collected 15*14=210 cans in total
210-192=18 cans the girls collected more than the boys
Answer:
The car was travelling at a speed of 60 miles per hour.
Step-by-step explanation:
Given:
Distance traveled = 330 miles
Time Period =
we need to find the speed of the car .
Solution:
Time Period =
Now we can say that;
So Time period =
Now we know that;
Distance traveled is equal to Speed multiplied by Time Period .
framing in equation form we get;
Dividing both side by 5.5 we get;
Hence The car was travelling at a speed of 60 miles per hour.
I don't know if we can find the foci of this ellipse, but we can find the centre and the vertices. First of all, let us state the standard equation of an ellipse.
(If there is a way to solve for the foci of this ellipse, please let me know! I am learning this stuff currently.)
Where
is the centre of the ellipse. Just by looking at your equation right away, we can tell that the centre of the ellipse is:
Now to find the vertices, we must first remember that the vertices of an ellipse are on the major axis.
The major axis in this case is that of the y-axis. In other words,
So we know that b=5 from your equation given. The vertices are 5 away from the centre, so we find that the vertices of your ellipse are:

I really hope this helped you! (Partially because I spent a lot of time on this lol)

First round
137,638=100,000
52,091=50,000
Then add to get the estamate
100,000
+
50,000
150,000
Then to get the real answer add

She has $55. She spent $22.50 on rides so now she has $32.50 . Then she spends $14.25 on lunch and snack so now she has $18.25.
A. would be wrong because Courtney IS correct, she has $18.25 left.
C. is also wrong because, again, Courtney IS correct.
So the only option left is B and it explains why Courtney is correct.
Option B is the correct answer.
Hope this helps.
