Answer:
Compound Interest Formula Solved For Rate:
log (1 + rate) = {log(total) -log(Principal)} ÷ Years
log (1 + rate) = {log(5,800) -log(5,000)} ÷ 5
log (1 + rate) = [3.7634279936 -3.6989700043] / 5
log (1 + rate) = 0.0644579893 / 5
log (1 + rate) = 0.0128915979
Then we raise 10 to the power of 0.0128915979 which equals
1.0301289629 = 1 + rate
Therefore, rate = .0301289629 and we multiply by 100 to make a percentage:
3.01289629 %

Step-by-step explanation:
Answer: 6 x 7 = 42
Step-by-step explanation: I believe this is because there are 6 different ways from the school to the park and seven routes from the park to his grandmother's house. To find the total you multiply 6 and 7.
Answer:
22(c)
Step-by-step explanation:
Our current proportion is
15 miles
-------------
1 hour
We need feet per second.
Lets convert!
15 miles= 79200 feet(used googl to find this)
1 hour=3600 seconds(also used googl to find this)
( i know its not spelled that way brainly wont let me write the whole word out)
Now, our proportion is:
79200 feet
-----------------
3600 seconds
HOWEVER, this can be simplified!!!!
79200/3600=22
Final answer: 22, or C.
I believe x=25 and y=10.
Step-by-step explanation:
Because we know the angles in a parallelogram add up to 360 degrees, we can add up values and divide to find x and y. 8y and 4x-20 are supplementary, they must equal the same value. Same with 10y and the other corner. By this, we can do 10y times 2 and 8y times 2 to get 16y plus 20y, or 36y. Then, we divide 360 degrees by 36. We get y=10 from this. Plug in 10 to 8y and get 80 as the upper left angle measurement. This means that 4x-20 equals 80. Add 20 to 80 on both sides so it cancels out and you get 100=4x. Simply divide and you will get x=25. To make sure this is right, plug all the numbers in and make sure all of the angles add up to 360. Hope this helps :)
Answer: 5x and 2
Explanation:
15x^2 + 6x
= 3x(5x) + 3x(2)
