Answer:
x=15√2 y=90 degrees.
Step-by-step explanation:
Thanks to the Pythagorean Theorem we know that with any right triangle, A^2+B^2=C^2. In this case we can use 15^2+15^2=sqrt of 450. The square root of 450 is 15 times the square root of 2. Thus x=15√2. Now we need to find y. All angles in a triangle add up to 180 so if we have 45+45+y=180 then y=90.
There are 8 sets of 21 cups in 168 cups so 9 times 8 is 72
6^9 x 6^-7 = 6^2
x= -7

Answer:
I believe that Tony will have to work 16 or 17 hours to have enough money to buy the TV
Step-by-step explanation:
$276.99 - 135 = $141.99
$8.50 x 8 = $68
$8.50 x 16 = $136
$8.50 x 17 = $144.50
$8.50 x 33 = $280.50
$136 < $141.99 $144.50 > $141.99
$8.50 x 16 or $8.50 x 17
Check to see if the numbers are correct.
If they are you will have to make a choice.
I hope this helped. ☺
