To do this simply see how many times 10 can go into 124.

It can go in 12 times right?

12 is your whole number.

The four is still left and it is going to stay there. So right now you have:
12 and 4/10

4/10 can be simplified by dividing it by 2.

This leaves you with 2/5

Your answer is 12 and 2/5

Step-by-step explanation:

to find range find the lower number and subtract from the biggest number..

so the the bigger number is 54 and the lower number is 3 so you would have to do is 54-3=51

If the range of the function f(x) = 7x – 2.7 is {14.1, 30.9, 41.4, 58.9, 68}, what is its domain?

Drupady [299]

domain is {2.4, 4.8, 6.3, 8.8, 10.1 }

For domain, equate f(x) to each value in the range and solve for x

7x - 2.7 = 14.1 ⇒ x = $\frac{x14.1 + 2.7}{7}$ = 2.4

7x - 2.7 = 30.9 ⇒ x = $\frac{30.9 + 2.7}{7}$ = 4.8

7x - 2.7 = 41.4 ⇒ x = $\frac{41.4 + 2.7}{7}$ = 6.3

7x - 2.7 = 58.9 ⇒ x = $\frac{58.9 + 2.7}{7}$ = 8.8

7x - 2.7 = 68 ⇒ x = $\frac{68 + 2.7}{7}$ = 10.1

What is the area of a sector with a central angle of (2pi/3) radians and a diameter of 12 in?

Stels [109]

Answer:

The area of the sector is $37.68\ in^{2}$

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=12/2=6\ in$ ----> the radius is half the diameter

substitute

$A=(3.14)(6)^{2}$

$A=113.04\ in^{2}$

step 2

Find the area of a sector with a central angle of (2pi/3)

Remember that

The area of $113.04\ in^{2}$ subtends a central angle of $2\pi \ radians$

so

by proportion

Let

x----> the area of the sector

$\frac{2\pi}{113.04}=\frac{(2\pi/3)}{x}\\ \\x=113.04*(2\pi/3)/(2\pi)\\ \\x=37.68\ in^{2}$
