The answer is B. She sells each orange for $0.50 and the question is asking for the total amount of money she will make by selling a certain amount of oranges. t represents the total so the equation will to equal to t. c is the number of oranges she will sell so c multiplied by $0.50 will give the total amount of money she will make.

The answer is B. This is because "t" is what Karen will raise so that will be the total, and then she sells the oranges for 0.50 so if Karen sells "c" amount of oranges we don't actually know how many she sells so you would do c multiplied by 0.50 to get t=0.50c.

Answer:

$y=1/2x+2$

Step-by-step explanation:

Know that: $y=mx+b$

Starting for (0,0) count how many times you go up to the marked line (which is 2)

$y=1/2x+2$

The [+] 2 is where you would start off at on the graph, with 1/2 being the slope go up one and over two.

What is the rate of heat transfer required to melt 1-ton of ice at 32 F in 24 hours?

LiRa [457]

Answer:

3865.74 J/s

Step-by-step explanation:

mass of ice, m = 1 ton = 1000 kg

time , t = 24 hours

latent heat of fusion of ice, L = 334000 J/kg

Heat required to melt, H = m x L

where, m is the mass of ice and L be the latent heat of fusion

So, H = 1000 x 334000 = 334 xx 10^6 J

Rate of heat transfer = heat / time = $\frac{334\times 10^{6}}{86400}$

Rate of heat transfer = 3865.74 J/s

thus, the rate of heat transfer is 3865.74 J/s.

What is the greatest perfect square of 1290

Alex73 [517]

<span>It has no perfect square factors, unless you count 1 = 1^2. That's sort of a degenerate case we don't usually count, since every integer has that factor. We would usually say that 1290 is a square-free integer. Hope this helps!!</span>

Central Allen High School's girls golf team has won 76% of its games this year. The team has won 19 games. How many total games

lawyer [7]

Answer: 25 games

Step-by-step explanation:

Take the fractions 76/100 and 19/x

Cross multiply. 76 times x equally 76x and 100 times 19 equals 1900.

Divide 76x by 76 which equals just x.

Divide 1900 by 76 which equals 25.

x=25
