A cylindrical can containing pieces of fruit is filled to the top with syrup before being sealed. The base of the can has an are

LekaFEV [45]

Answer:

The total volume of the pieces of fruit in the can is $640\ cm^{3}$

Step-by-step explanation:

step 1

Find the volume of the cylindrical can

The volume of the can is equal to

$V=BH$

where

B is the area of the base of the can

H is the height of the can

we have

$B=75\ cm^{2}$

$H=10\ cm$

substitute

$V=(75)(10)=750\ cm^{3}$

step 2

Find the volume of the pieces of fruit in the can

The volume of the pieces of fruit in the can is equal to subtract the volume of syrup from the volume of the can

$750\ cm^{3}-110\ cm^{3}=640\ cm^{3}$

You earn $28 for washing 7 cars. How much do you earn for washing 6 cars?

iren [92.7K]

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━

Since you can earn 28 dollars by washing 7 cars, and you want to find the amount money you can make by washing 6 cars.

$\frac{28}{7} = \frac{x}{6}$

First, you should find the amount of money you can make by washing 1 car (unit rate).

$\frac{28}{7} = \frac{x}{1}$

To get from 7 to 1, you have to divide 7 by 7; 7 ÷ 7 = 1.

Do the same thing to the numerator; 28 ÷ 7 = 4.

Now you know how much you make by washing 1 car, you need to find how much you make by washing 6 cars.

$\frac{4}{1} = \frac{x}{6}$

To get from 1 to 6, you multiply by 6. 1 times 6 equals 6.

Now do the same thing to the numerator; 4 × 6 = 24.

You can earn 24 dollars by washing 6 cars.

Plz plz plz help me with this

This question wants you to find a common denominator for the fractions.
This means finding the LCM, least common multiple, for 21 and 9.
This can be done by listing the multiples for each number until they meet at a common one.

9:
9
18
27
36
45
54
63

21:
21
42
63

This means the LCM of 21 and 9 is 63.
So the lowest possible common denominator is 63.

21 • 3 = 63
So you have to multiply the numerator of 2/21 by 3 as well.
2 • 3 = 6
2/21 = 6/63

Now do the same for 1/9.
9 • 7 = 63
Multiply the numerator, 1, by 7.
1 • 7 = 7
1/9 = 7/63

So in the first blanks, you would put 6/63 for what 2/21 is equal to and 7/63 for what 1/9 is equal to.

7/63 is greater than 6/63.
7/63 > 6/63
That means 1/9 > 2/21
So 2/21 < 1/9 is the answer to the last blank.

Hope this helps!
