How many eighty fours are in 672

Answers

Answer 1
Answer:

Answer

Find out how many eighty fours are in 672.

To prove

Let us assume that the number of the 84 be x .

As given in the equation

Total values  given in the question be 672.

Than the equation becomes

84 × x = 672

Simplify the above equation

84x = 672

x = (672)/(84)

x = 8

Therefore the Numbers of eighty fours in 672 is 8 .
Answer 2
Answer:

The number of eighty fours in 672 is 8

  • How many eighty fours are in 672
  • Let x represent the number of the 84 (can be expressed as 84 x X)

Further Explanation

And since we have 672 as the total value,

Therefore, you have:

84 x X = 672

84x = 672 (then determine the value of x)

X= (672)/(84)

X = 8

Thus, the number of eighty fours in 672 is 8.

Prove:

= 84 x 8

= 672

Notably, eighty fours is expressed as 84

You can also solve this question easily by following this step:

It is same as saying how many 84’s are in 672 (it means you should divide 672 and 84)

= (672)/(84)

= 8

Check out these 2 examples:

Example 1

How many eighty fours are in 4200 (same as how many 84’s are in 4200)

= (4200)/(84)

= 50

Prove:

= 84 x 50

= 4200

Example 2

How many eighty fours are in 840 (same as how many 84’s are in 840)

= (840)/(84)

= 10

Prove:

= 84 x 10

= 840

How do you do, Increase £28 by 7%

Answers

The best thing is to find 1%. In order to do this, divide £28 by 100 & this gives you £0.28, then multiply this by 7 (as you're looking for 7%), and this gives you £1.96. You've then got to add these together, and that gives you £29.96Hope this helps :)
I would find 5% so find ten percent which is £2.80 ( you just divide it by ten ) then half it £1.40 after that find 1% which is 28p (divide by 100) then add £1.40 and 28p which is £1.68 then add it to £28 which is ££29.68. That is what I would do but people like to do it other ways so..... Hope this helped you on how to answer these sort of questions

Find the volume of soup can if the diameter is 6.5 in and the height is 9 in

Answers

Answer:

V =298.49625 in^3

Step-by-step explanation:

Volume of a cylinder is given by

V = pi * r^2 *h

We know the diameter so we can find the radius

r = d/2 =6.5/2 = 3.25

and we know the height =9

V = pi * (3.25)^2 *9

V = pi*95.0625

If we approximate by 3.14

V = 3.14*95.0625

V =298.49625 in^3

Answer:

V = 95.0625\pi inches

Step-by-step explanation:

The soup can is a cylinder, and since the diameter is 6.5 inches then the radius is 3.25 inches. The formula for the volume of a cylinder is V = \pi r^(2)h, and by plugging in the values we have, we get V = \pi *3.25^(2) *9.

Solving this equation gives us V = 95.0625\pi inches.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Dawn bought 12 grams of chocolate.

Here, She ate half of the chocolate.

Hence, The amount of eat chocolate = 12 / 2 grams

                                                          = 6 grams
