9 miles is approximately equal to 16 km. How many km are equal to 63 miles? How many miles are equal to 48 km?
Vikki [24]
The first answer is 112 because you multiply 9 by 7 to get 63 and then you multiply 16 by 7 to get 112. and the second one is 27 because 16 times 3 equals 48 so then you multiply 9 by 3 to get 27.:)

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by
sweet [91]

Hey Child.

The answer to this is 1 or 7:

To find the range for the number of measures played to satisfy our solution, we must solve for x using s = 80.

Next, we subtract 50 from both sides of the equation.

Next, we divide both sides of the equation by 10

Next, to eliminate the absolute value bars, we will add a ± sign in front of our s value, 3.

Finally, we add 4 to both sides of our equation giving us 4 ± 3 = x

Separating this into two equations, we get 4 - 3 = x and 4 + 3 = x

Therefore, x, the number of measures of music played, must be either 1 or 7.

The quotient of the opposite of 30 and 6 plus the opposite of 8
Alina [70]
First, let's turn this sentence into a mathematical expression:
The quotient of the opposite of 30 and 6 means we're dividing negative 30 by 6. The next part, "plus the opposite of 8" means we want to add -8 to whatever we get from -30/6. So we have:
\frac{-30}{6}+(-8)
-5+(-8)
-13

A car was valued at $44,000 in the year 1993. The value depreciates to $15,000 by year 2002.
almond37 [142]

Answer:

The car will have lost it's total value by 2007.

Step-by-step explanation:

If initially the car was valued at 44,000$, and after 9 years it's value dropped to 15,000$, we can say that the car's value dropped in 29,000$. If we suppose that the drop is the same every year, we can say that it was of 3,222,2$ by each year.

This amount of money is the 7,3% of the initial value of the car (I multiplied 3,222,2 x 100 : 44,000).

a) The annual rate of change was of 7,3%.

b) There are 14 years between 1993 and 2007. If we multiply 7,3% by 14, we get that the car lost 102,2% of it's initial value.
