A red candle is 8 inches y'all and burns at a rate of 7 divided by 10 inch per hour. A blue candle is 6 inches tall and burns at

lorasvet [3.4K]

Answer:

Both candles will have the same height after 4 hours.

Step-by-step explanation:

The equation for the amount of candle remaining can be given by the following equations:

$Q(t) = Q(0) - at$

In which Q(t) is the amount after t hours, Q(0) is the initial amount and a is how much it decreases, in inches, per hour.

Red candle:

8 inches tall and burns at a rate of 7 divided by 10 inch per hour. This means that $Q(0) = 8, a = 7/10 = 0.7$ . So

$Q_{r}(t) = 8 - 0.7t$

Blue candle:

6 inches tall and burns at a rate of 1 divided by 5 inch per hour. This means that $Q(0) = 6, a = 1/5 = 0.2$ . So

$Q_{b}(t) = 6 - 0.2t$

After how many hours will both candles be the same height ?

This is t when

$Q_{r}(t) = Q_{b}(t)$

$8 - 0.7t = 6 - 0.2t$

$0.2t - 0.7t = 6 - 8[/yrc][tex]-0.5t = -2$

Multiplying by (-1)

$0.5t = 2$

$t = \frac{2}{0.5}$

$t = 4$

Both candles will have the same height after 4 hours.

The formula for the volume of a sphere is V=4/3πr³, where V is the volume and r is the radius. Solve the formula for r, and then

3241004551 [841]

Answer:

4.5 inches to the nearest tenth

Step-by-step explanation:

V=4/3πr^3

Divide both sides by 4/3π:

r^3 = V / 4/3π

r = ∛ (V / 4/3 π)

When V = 371 inches:

r = ∛ (371/ 4/3 π)

= 4.46 in

Meat costs $8.00 per pound at a store. What is the slope?

-BARSIC- [3]

Answer:

The slope is 8.

Step-by-step explanation:

If you were to graph the price of meat per pound, you would need to choose the x-axis and y-axis labels.

The x-axis is the independent variable, meat in pounds.

The y-axis is the dependent variable, price in dollars.

The price depends on the number of pounds you buy.

Slope is calculated using rise over run, or:

$m = \frac{rise}{run}$

"Rise" is the number of squares going up.

"Run" is the number of squares going to the right.

In the graph below, to go from one red dot to the next, you count 1 to the right and 8 going up.

$m = \frac{rise}{run}$

$m = \frac{8}{1}$

$m=8$

Therefore, the slope is 8.
