Well, 1/3 = 428 so that you could get the same thing as 28 75 hours for you to go to school
The approximate difference in their volumes is 17.2 cubic inches
<h3>How to determine the difference in the volume?</h3>
The given parameters are:
Diameter, d = 2.8
Diameter, D = 3.8
The radii are the half of the diameter.
So, we have:
r = 1.4
R = 1.9
The volume of the balls is then calculated using:

The difference is then represented as:

Substitute known values

Evaluate
D = 17.2
Hence, the approximate difference in their volumes is 17.2 cubic inches

Answer: $5100
Step-by-step explanation:
Given, The prize money starts at $20 for the first question.
Let a= 20,
Also, Each question is tougher than the one before it, and the station doubles the prize money from the previous amount.
i.e. the sequence prize willbe : $20 , 2 x ($20) , 2² x ($20)x ....
That is its is an geometric progression with the common ratio r= 2,
Since the sum of n terms in GP is given by :-

So the total money will it hand out in prizes after 8 questions would be :

Hence, the total money it will hand out in prizes = $5100
Answer:
130
Step-by-step explanation:
Given the equation of the relation as c(h) =50 +20 h where c(h) is the total cost for h hours and h is the number of hours of use, then to find the cost of jet ski if 4 hours were used will be;
c(h)=50 +20 h
c(4)=50 +20*4
c(4)=50 +80
=130
Answer:
Number line C
Step-by-step explanation:
First, you isolate x. This gives you x>=3+4 or x>= 7. Next, you find a number line greater than or equal to which cancels out A and D. Now whichever line starts on 7, is the answer which is C
