3 0

Answer:

The real answer is 12 round and 24 square candles. The top answer is wrong because she just guessed.

Step-by-step explanation:

4r+6s=192

s=2r

Solve:

4r+6(2r)=192

4r+12r=192

Combine like terms

16r=192

r=12

s=2(12)

s=24

12 round candles and 24 square candles

If you were to write the equation of this line in the form y=mx+c what is the value of m
marusya05 [52]

Answer:

B choice.

Step-by-step explanation:

The graph decreases. Therefore, the slope is in negative. We can rule out A and C choices.

It is very obvious to tell because of steepness. Low steepness = low value

High steepness = high value.

We can also find the slope by using rise/run.

m =  \frac{dy}{dx}

The change of y over the change of x.

Given the coordinate points (0,1) and (4,0). Both points are part of the graph.

m =  \frac{y_2 - y_1}{x_2 - x_1}

m =  \frac{1 - 0}{0 - 4}  \\ m =  \frac{1}{ - 4}  \\ m =  -  \frac{1}{4}

Therefore the value of m is - 1/4

A mammal's surface area can be calculated by using the equation S(m) = km where s(m) is the surface area in square centimeters,
Virty [35]

Answer: 706 grams

Step-by-step explanation:

s(m) = km

So 6000 = 8.5m

Divide both sides by 8.5 to isolate m

6000/8.5 = 8.5m/8.5

705.88 = m

m = 706 (rounding up)
