Candle store sell 20 candles for a total of 356 dollars. Small candles are $11 and large candles are $28 . How many large candles did they sell?

8 large candles.

Step-by-step explanation:

So imagine they sold x small candles, then they sold 20-x large candles.

We can list out an equation:

11x+28×(20-x)=356

11x+560-28x=356

-17x=-204

x=12

Large candles:20-12=8

Have a nice day! :)

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
