Find the difference and write it in simplest form 7 3/8 - 2 7/9

1 answer:

4 0

Well first you have to turn the mixed number into a improper fraction.
7 2/8=59 over 8
2 7/9=25 over 9
Then u would multiply the 59 by 9 and 8 by 9 and u should get 531 over 72 and for the second fraction u should multiply the 25 by 8 and the 9 by 8 and you should get 200 over 72 as a improper fraction.
Then you have to subtract 531 over 72 by 200 over 72 and u should get 231 over 72 which is 4 and 43 over 72 when simplified.
The answer: 4 43/72
Hope this helps!!!!

a circle with radius of 2cm sits inside a 7cm x 11cm rectangle. what is the area of the shaded region ?

Agata [3.3K]

Answer:

The area of the shaded region is $(77-4\pi)\ cm^{2}$

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of the rectangle minus the area of the circle

step 1

Find the area of the rectangle

$A=(7)(11)=77\ cm^{2}$

step 2

Fin the area of the circle

$A=\pi (2)^{2}=4\pi \ cm^{2}$

step 3

Find the area of the shaded region

$77\ cm^{2}-4\pi \ cm^{2}=(77-4\pi)\ cm^{2}$ -----> exact value

To find the approximate value use $\pi=3.14$

$(77-4(3.14))=64.44\ cm^{2}$ -----> approximate value

A batch of snack mix made of dried fruit and nuts contain 744G of nuts the ratio of nuts to dried fruit by weight is 12 to 13 ho

mixer [17]

In a bag of snack mix:

n = nuts d = dried fruit

n = 744g d = ???g

Ratio Nuts/Dried fruit = 12/13

This basically means that if the mix was divided in 25 parts, 12 parts would be nuts and 13 would be dried fruits

If 744 is 12 parts then 744/12 is 1 part

744/12 = 62

1 part = 62g

there are 13 parts of dried fruit

13 x 62 = 806

744g of nuts + 806g of dreid fruit = 1550g

Answer: A batch of snack mix weigh 1550g, or 1.55kg

hope it helps :)
