Mikaela travels 15 blocks on her skateboard in 5 minutes. At this speed, how many blocks can she travel on her skateboard in 12
Alchen [17]

Answer:

36 blocks.

Step-by-step explanation:

We have been given that Mikaela travels 15 blocks on her skateboard in 5 minutes. We are asked to find the number of blocks that she can travel on her skateboard in 12 minutes.

We will use proportions to solve our given problem.

\frac{\text{Blocks traveled}}{\text{Time taken}}=\frac{15}{5}

\frac{\text{Blocks traveled}}{12}=\frac{15}{5}

\frac{\text{Blocks traveled}}{12}\times12=\frac{15}{5}\times12

\text{Blocks traveled}=3\times12

\text{Blocks traveled}=36

Therefore, Mikaela will travel 36 blocks on her skateboard in 12 minutes.

Evaluate 5c+cd5c+cd5, c, plus, c, d when c=\dfrac15c=
zepelin [54]

Answer:

4

Step-by-step explanation:

The function is given as 5c+cd, c=1/5 and d=15d.

We evaluate by substituting the given values of c and d in the function:

5c+cd, c=1/5 \ \ \, d=15\\\\=5\times \frac{1}{5}+\frac{1}{5}\times 15

=1++3\\\\=4

After substituting, we find the function's equivalent as 4.

Hence, the value of the function is 4

Step-by-step explanation:

The formula for simple interest is I = Prt, where P = principal, r = interest rate, t = time (usually in years), and I = amount of simple interest.

  • 120 × 0.03 × 2
  • 3.6 × 2
  • 7.2
  • $7.20

Thus, the answer is $7.20.

KatRina [158]

Answer:

x^2 - 5x - 66

Step-by-step explanation:

1. Distrubute the x to the x and -11 so you will get x^2 - 11x

2. Distrubute the 6 to x and -11 and you get 6x - 66

3. Combine like terms (x^2 - 11x + 6x - 66) you will get x^2 - 5x - 66
