Answer:

C.\frac{1}{x^{12}}

Step-by-step explanation:

We are given that an expression

(x)^{-12}

We have to find the simplified form of given expression.

We know that

a^{-b}=\frac{1}{a^b}

Using the property then we get

x^{-12}=\frac{1}{x^{12}}

Hence, the simplified form of x^{-12} is given by

\frac{1}{x^{12}}

Option C is true.

natali 33 [55]

Answer:

10.99 feet

Step-by-step explanation:

The arc length when an angle of 360° is made is the perimeter of the circle.

Perimeter = π*Diameter = π*30 = 94.25 ft

To know the arc length when an angle of 42° is made, we need to use the following proportion

94.25 ft / x ft = 360° / 42°

x = 42/360*94.25

x = 10.99 ft

Malik's solution to the equation , when , is shown below. What error did Malik make first when solving the equation ? Malik did
Marianna [84]

Answer:

Malik substituted 60 for y instead of x.

Step-by-step explanation:

According to the given situation the computation of error that Malik make first when solving the equation is shown below:-

First, we will find the value of x

\frac{2}{5} x - 4(60) = 10

\frac{2}{5} x = 10 + 240

\frac{2}{5} x = 250

x = 625

Now, we have

\frac{2}{5} x - 4 y = 10

we will solve the above equation, to find the value of y

24 - 4y = 10

4y = 24 - 10

4y = 14

y = \frac{14}{4}

y = \frac{7}{2}

So, from the above calculation, the correct option is

Malik substituted 60 for y instead of x.

Kevin can travel 22 1/2 miles in 1/3 hour. What is his average speed in miles per hour?
cestrela7 [59]
Divide the miles he traveled by the time it took him to travel it.

22 1/2 / 1/3

Multiply by the reciprocal of 1/3:

22 1/2 * 3/1

Convert 22 1/2 into an improper fraction:

45/2 * 3/1

Multiply the numerators and denominators together:

135/2

Divide:

67.5 or 67 1/2

So his average speed in miles per hour is 67 1/2.
