The area of a circle is 49π in². What is the circumference, in inches? Express your answer in terms of \piπ.

Answers

area of circle =  π r²

π r²= 49 π

r²= 49             r= √49                  r= 7

circumference of circle = 2 π r

                                       = 2×7 × π

                                       = 14 π

The circumference of a circle is 14π.

What is a circle?

A circle is a two-dimensional figure with a radius and circumference of πr.

The area of a circle is πr².

We have,

Area of a circle = 49π in².

Area of a circle = πr²

Now,

πr² = 49π

r² = 49

r = 7

Now,

Circumference of a circle.

= 2πr

= 2π x 7

= 14π

Thus,

The circumference of a circle is 14π.

Suppose two trains, say A and B are initially 125 miles apart on the same east-west track. Train A is initially to the west of train B. Train A begins to head due east at 25 mph, and train B begins to head due west at 20 mph. To the nearest minute, how long will it take for the two trains to collide?

Answers

Answer:

[tex]167\ \text{minutes}\text{ or }166\ \text{minutes}\ \text{and}\ \text{40}\ \text{seconds}[/tex]

Step-by-step explanation:

Distance between the two trains is 125 miles.

So, when they will collide they would have covered a distance of 125 miles together.

The time that will pass for both the trains will be same but the distances covered will be different as their speeds are different.

[tex]\text{Distance}=\text{Speed}\times \text{Time}[/tex]

[tex]25t+20t=125\\\Rightarrow t=\dfrac{125}{45}\\\Rightarrow t=\dfrac{25}{9}\ \text{hours}=\dfrac{25}{9}\times 60\times 60=10000\ \text{s}=166.67\ \text{minutes}\\\approx 167\ \text{minutes}\\=166\ \text{minutes}\ \text{and}\ \text{40}\ \text{seconds}[/tex]

Krutika and Natasha win some money and share it in the ratio 4:3. Krutika gets £7 more than Natasha. How much did they get altogether?

Answers

Answer:

49

Step-by-step explanation:

The computation of the total amount is shown below:

Let us assume the natasha be 4x

And, the krutika be 3x

Now as per the situation

4x = 3x + £7

x = £7

For natasha = 4(7) = 28

For krutika = 3(7) = 21

So, the total amount is

= 28 + 21

= 49

-6w-8+1-7w

-6w-7w-8+1

-13w-8+1

-13w-7

Answer:

B. -13w-7

Step-by-step explanation:

First, let's simplify the problem by grouping the like terms together: (-6w),  (-7w), and (-8), (1).

Second, now that you know the like terms solve them each individually:

(-6w) + (-7w) = -13w

(-8) + 1 = -7

So your answer is -13w minus -7

Find f^-1(x) where

Answers

Given:

Consider the function is

[tex]f(x)=\dfrac{3x+2}{x}[/tex]

To find:

The inverse of the function, .i.e., [tex]f^{-1}(x)[/tex].

Solution:

We have,

[tex]f(x)=\dfrac{3x+2}{x}[/tex]

Putting f(x)=y, we get

[tex]x=\dfrac{3y+2}{y}[/tex]

Isolate the variable y.

[tex]xy=3y+2[/tex]

[tex]xy-3y=2[/tex]

[tex]y(x-3)=2[/tex]

[tex]y=\dfrac{2}{x-3}[/tex]

Putting [tex]y=f^{-1}(x)[/tex], we get

[tex]f^{-1}(x)=\dfrac{2}{x-3}[/tex]

Therefore, the inverse function is [tex]f^{-1}(x)=\dfrac{2}{x-3}[/tex].
