1. The square on the inside is 8 x 8 = 64
2. The triangle's area is 8x9x1/2= 72 x 1/2 = 36
3. there are 4 triangles so 36 x 4 = (or 72 x 2 ) = 144 :)
A number outside of the square root symbol is actually multiplied by the square root of the number under the symbol. 25 and 9 are considered perfect squares because a number multiplied by itself goes evenly into each without any remainders.
=3√25 - √9
take the square root of 25 and 9
=3(5) - 3
multiply 3*5
=15 - 3
=12
ANSWER: 12 (first choice)
Hope this helps! :)
Answer:
linear pair
Step-by-step explanation:
The two angles add together to form a straight line, which is 180 degrees.
These angles are supplementary, or a linear pair
It would be 5 months because if you do 75 + 20x = 35x
15x = 75

Answer:
Step-by-step explanation:
Use the info given in the exponential equation to find the value of b, the rate of decay.
where v(t) is the value of the car after a certain number of years, t, have gone by, a is the initial value, and b is the rate of decay. We have everything we need but b:
a = 20000
v(t) = 16000 after t = 1 year:
so
b = .8 Taken in context, this means that the car depreciates 20% each year. Now we can solve the problem being asked of us, which is to find the value of the car after t = 5 years:
which simplifies down a bit to
v(t) = 20000(.32768) so
v(t) = 6553.60, choice C.
