spencer took 21$ with him to the mall. At the music store, he spent 2/3 of his money on a DVD, he spent 1/4 of what he had left

Sunny_sXe [5.5K]

Answer:

$5.25 Dollars

Step-by-step explanation:

I know that if you divide 21 by 3 you get 7. So, 2/3 of 21 is 14. He spent 14 dollars at the music store. This means that he has 7 dollars left. From here he spend 1/4 of 7 dollars on a drink. 1/4 of 7 is $1.75. This means that he has 5.25 dollars left after he bought the drink! :)

We have a right triangle that has am 8 meter and 21 meter leg .Find the hypotenuse

Serjik [45]

Answer:

hypotenuse is 22.47 m

Step-by-step explanation:

The length of both legs of a right angle triangle are 8m and 21 m

We need to find the hypotenuse

To find hypotenuse we use Pythagorean theorem

Hypotenuse is AC and other two legs are AB and BC

$AC^2 = AB^2 + BC^2$

Hypotenuse ^2 = 8^2 + 21^2

hypotenuse = $\sqrt{8^2 + 21^2}$

= $\sqrt{64 + 441}$

= $\sqrt{505}$

= 22.47

So the length of the hypotenuse is 22.47 m

Ending time 6:30, elapsed time 37 minutes

Nastasia [14]

Answer:

5:53

Step-by-step explanation:

The original time would be 37 minutes before 6:30 so you would subtract 37 minutes from 6;30. So 6:30 minus 30 would be 6 and you would have 7 left over so 6:00 minus 7 minutes would be 5:53
