20/100 x 8000 = 1600
1600 x 3 = 4800
8000 - 4800 = 3200
The motorcycle is worth $3,200 after three years.
10 sides
360-72=288
288 divided by 2 is 144
Decagon have 144 degree interior angles
2(3x + 5) (x - 1)
This is done through factoring 2 out of the equation first...
2(3x^2 + 2x -5)
And then cross multiplying it
I'm assuming the question is asking how tall the tree is if it has grown 2 3/4 inches.
The initial height of the tree is 74 3/8 inches and it grows 2 3/4 inches after six months. We can add these two numbers together to calculate the height of the tree now.

Since these are both mixed numbers, we must find a common denominator to add our fractions. 8 is the lowest common denominator for 4 and 8. So:

We can now add our whole numbers up (74 + 2) and add the numerators of the fractions together to get a single fraction (
).
74 + 2 = 76

Putting these two together, we get
, which is equal to
.
We can also turn this answer into an improper fraction. This is done by multiplying the whole number by the denominator and adding the numerator. So in this case:
77 x 8 = 616
616 + 1 = 617
The denominator stays the same, so our answer as an improper fraction would be
.
So the tree is
inches tall, or
inches tall.
Answer:
A =153.9 cm^2
Step-by-step explanation:
We know the area of a circle is given by
A = pi r^2
We are given the radius and pi
A = 3.14 (7)^2
A =153.86 cm^2
Rounding to the nearest tenth
A =A =153.9 cm^2
