Hello !
p = 100e^0.07t = 100[e^(0.07)]^t = 100·1.0725^t
Then the annul percent growth rate is 7.25%.
When lines cross each other in a triangle from a point to the mid point of the opposite side as shown, AV is 2 times as long as VF
To solve for X we would have AV = 2*VF
The equation becomes:
3x+6 = 2(x+6)
Now we solve for X
3x+6 = 2(x+6)
Distribute the 2 on the right side:
3x + 6 = 2x +12
Subtract 2x from each side:
X +6 = 12
Subtract 6 from each side:
x = 6
Now if you needed to solve the length of AV or VF, you replace x with 6 and solve.
Answer:
52.5 days
Step-by-step explanation:
Ten people can dig 2 acres in 7 days.
One person can dig 0.2 acres in 7 days.
Working at half the rate, one person can dig 0.1 acre in 7 days.
8 people can dig 0.8 acres in 7 days.
8 people can dig 6/0.8 * 0.8 acres in 6/0.8 * 7 days.
8 people can dig 6 acres in 52.5 days
Ten (10) times (multiplication) the sum (addition) of half (
a number (n) and 6 is (=) 8.
10(
+ 6) = 8 Use the Distributive Property
5n + 60 = 8 Subtract 60 from both sides
5n = -52 Divide both sides by 5
n = -10
