Mechanical Advantage = Force by Hammer / Force by Nail = 160/40 = 4
Since 1 km = 1000 m, the lawnmowers top speed would be 8000 m/h.
$7881.18
Step-by-step explanation:
Let the initial Investment be
. The Interest is compounded on a monthly basis at 12% annual interest rate. After 17 years, the Investment amounts to $60,000.
As the annual interest rate is 12%, the monthly interest rate is 1%.
Since this is a compound interest problem, the total amount can be modeled as follows: 
Here
is the interest rate, i.e
, and t is the number of time periods, i.e
= 


∴ Initial Investment = $7881.18
Answer:
(3-x) is the other factor.
Step-by-step explanation:
The given function is :

One of the factor is (x-4)
We need to find the other factor.
It can be solved as follows :

So, the other factor is (3-x).
If both the hoses are on the same time then the height of the water in the pool is given by the expression 15g^2 + 5g - 6
Step-by-step explanation:
(7g^2 + 3g - 4) + (8g^2 + 2g - 2)
= (7g^2 + 8g^2) + ( 3g + 2g) + (-4 -2)
with the help of distribution law,
= (7 +8)g^2 + (3 + 2)g - (4 + 2)
= 15g^2 + 5g - 6
Therefore if both the hoses are on the same time then the height of the water in the pool is given by the expression 15g^2 + 5g - 6
