A red candle is 8 inches tall and burns at a rate of 7/10 inch per hour.

ira [324]

Answer:

11 3/7 hours

Step-by-step explanation:

The shorter candle burns faster, so the candles will not be the same height (0) until the taller candle burns completely. At 0.7 in/h, that will take ...

(8 in)/(0.7 in/h) = 80/7 h = 11 3/7 h

(-1,2p³q)(10p²r²)=<br> Help me

MaRussiya [10]

For this case we have the following expression:
$(-1.2p^3q)(10p^2r^2)$
When making multiplication, the first thing you should keep in mind is the following property:
Same basis, the exponents are added.
We have then:
$-12p^{3+2}r^2q$
Rewriting we have:
$-12p^{5}r^2q$
Answer:
The simplified expression is given by:
$-12p^{5}r^2q$

The perimeter of a square is 52 meters. What is it area.

ValentinkaMS [17]

Answer:

169 meters

Step-by-step explanation:

52/4=13 (since it's a square you divide it by 4 because the sides are equal, so each side is 13 meters)

13^2=169 (to find the area you square the length of each side)

Applying the Quadratic Formula

Katyanochek1 [597]

Answer:

Step-by-step explanation:

The trick you need to employ is that when the rock hits the ground, the timer stops. So h must be taken as 0.

0 = - 16t^2 + 255 Set up the equation

- 255 = - 16t^2 Divide by -16

15.9375 = t^2 Switch

t^2 = 15.9375 Take the square root of both sides.

sqrt(t^2) = sqrt(15.9375)

t = 3.992 seconds

The closest answer is B
