A satellite flies 55584 miles in <br> 7.72 hours. How many miles has it flown in 23.19 hours?

dedylja [7]

Answer:

Miles flown in 23.19 hours = 166968 miles

Step-by-step explanation:

Given that:

A satellite flies 55584 miles in 7.72 hours

We will find the unit rate first,

Unit rate = $\frac{55584}{7.72}$

Unit rate = 7200 miles per hour

Miles flown in 23.19 hours,

Miles flown = 7200 * 23.19

Miles flown = 166968 miles

Hence,

Miles flown in 23.19 hours = 166968 miles

Sam paid $8.28 for 18 stamps. At this rate, how much would it cost sam to buy 12 stamps?

Korolek [52]

First we want to find how much it costs for 1 stamp, so we do 8.28 divided by 18, which equals 0.46. Then, we multiply 0.46 and 12, which is 5.52. Therefore, it would cost $5.52 to buy 12 stamps.

Find the quotient. Simplify if possible -6/10 + (-5/7)

Zepler [3.9K]

Answer: The correct answer is $\frac{21}{25}$

Step-by-step explanation:

To find a quotient, we need to divide the two numbers. The equation given to us is :

$\frac{-6}{10}\div \frac{-5}{7}$

To Simplify the above equation and finding out the quotient, we need to divide the above equation, we get:

$\Rightarrow \left(\frac{\frac{-6}{10}}{\frac{-5}{7}}\right)$

Taking the reciprocal of the denominator and multiplying it with the numerator, we get:

$\Rightarrow \frac{-6}{10}\times \frac{7}{-5}\\\\\Rightarrow \frac{42}{50}\\\\\Rightarrow \frac{21}{25}$

Hence, the correct answer is $\frac{21}{25}$
