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:

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

Salsk061 [2.6K]

Answer:

The height of the tree is 21 ft

Step-by-step explanation:

we know that

A light post that is 9 feet tall that casts a shadow that is 6 feet long

by proportion

Find out the the height of the tree if a tree that casts a shadow that is 14 feet long

Let

x ----> the height of the tree

$\frac{9}{6}=\frac{x}{14}\\\\x=9*14/6\\\\x=21\ ft$

therefore

The height of the tree is 21 ft

The principal P is borrowed at a simple interest rate r for a period of time t. Find the simple interest on for the use of the m

alex41 [277]

Answer:

$7.20

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.

Expand and simplify (x+6)(x−11)

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
