Answer:
(4%) ... $8200
Step-by-step explanation:
x + y = 15000
.04x + .032y = 545.60
y = 15000 - x
.04x + .032(15000 - x) = 545.60
.008x = 65.6
x=8200
12 hours..........
+ - = 1
Multiply by 12 to clear the fractions
3t + 2t - 4t = 12
t = 12 hrs to fill the pool
Answer:
True
Step-by-step explanation:
Even though we cannot see the parallelogram, we can assume the dimensions of the original parallelogram is height= 3 and base= 6.
If we double the dimensions, we get:
height=6 band base=12.
The area of the original parallelogram is 18 square units.
The area of the enlarged parallelogram is 6×12= 72 square units.
Now,

Hence, the area of the larger parallelogram is 4 times more than the original.
The answer to this for 13 is c I’m pretty sure I may be wrong
Answer:
The area 2730 possible arrangements of first, second, and third place.
Step-by-step explanation:
The order in which the students finish is important. For example A, B and C is a different finishing order(outcome) than B, A and C. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:

In this question:
3 from a set of 15. So

The area 2730 possible arrangements of first, second, and third place.
