184 - 124 = 60
so it has grown by 60 in 18 months. That is 3 1/3 per month.
so Number of citizens depending on month is 124 + (1 1/3)n
or 124 + 4n/3:
At population 1000:-
124 + 4n/3 = 1000
4n/3 = 1000-124
n = (1000-124) * 3/4 = 657 months
Answer:
<h2>C: 3 inches by 6 inches</h2>
Step-by-step explanation:
Notice that point A is a mid point. If we cut the prism though that point, perpendicular to the shaded face, it means the side of 4 inches will be divide in two equal parts, and the 3-6 inches face won't be cut.
Therefore, the dimensions of the cross section is 3 inches by 6 inches, which are the dimensions of the face that won't be cut, because they don't intersect with point A.
D. All rational numbers are integers
The answer is A because when y = 3^x is graphed the equation stays steady until -2 on the x plane then rapidly shoots up.
Answer:
<u>131 seats</u> are in the 30th row.
Step-by-step explanation:
The theater is designed with the first row there are 15 seats, in second row 19 seats and in the third row there are 23 seats.
Now, to find the number of seats in the 30th row.
So, we get the common difference(
) from the arithmetic sequence first:
Thus, 
So, the first tem 
= 15.
The number of last row (
) = 30.
Now, to get the number of seat in the 30th row we put formula:
Therefore, 131 seats are in the 30th row.
