Answer:

Yes, 15 miles.

Step-by-step explanation:

You need to use proportions. For example with biking:

\frac{48}{300} = \frac{b}{75}

Using cross products:

300b = 48(75)

300b = 3600

b = \frac{3600}{300} = 12

The same is true for running:

\frac{24}{240} = \frac{r}{30}

\frac{1}{10} = \frac{r}{30}

10r = 1(30)

10r = 30

r = 3

The total distance is the sum of these two:

d = b + r = 12 + 3 = 15

Answer:

\frac{1}{4}

Step-by-step explanation:

Since there are a total of 4 colors, and there are 5 of each colors, the total marbles in the bad would be;

5 x 4 = 20

If a color is selected at random the probability would be

\frac{part}{whole}

our part is 5

our whole is 20

so the probability would be;

\frac{5}{20} or \frac{1}{4} when reduced

Hope this helps!

According to the 2000 Census the population of Canton was 7,720. Holly Spring's population was 3,200. Canton's population increa
Kazeer [188]
Firstly, the rate of increase of Canton = 80/7720 = 0.010
The rate of increase of HP = 120/3200 = 0.0375
Apply  the formula of compound interest==> A =A'(1+i)^n
The population will be equal when the following equality is satisfied

7720(1+0.01)^n = 3200(1+0.0375)^n

or

7720x1.01^n = 3200x1.0375^n

Divide both sides by 3200 ===>(193/80)x1.01^n=1.0375^n
