To find the discount, simply multiply the original selling price by the %discount:

ie:  39 x ³³/₁₀₀= $12.87

So, the discount is $12.87.

To find the sale price, simply minus the discount from the original selling price:

ie: 39- 12. 87=  26.13

So, the sale price is $26.13

Since you want equal amounts in each glass, divide the total amount of juice, 577 pints, by the number of glasses, 15.]

ie 577 ÷ 15= 38.4666666666666667.

So you'd have to pour 38.4666666666666667 pints in each glass

Simply multiply by 100 and add the %.

that is, 5.4 x 100= 540%. Just move the decimal place 2 places to the right.

7/8 is bigger.

Simply change the numbers to the same form, whether both to decimals or both to fractions. That way you'll easily see which is bigger

 so changing both to decimal gives:

7/8 is 0.875 which is bigger than 0.78

So use BOMDAS (Brackets of Multiplication,  Division, Addition and Subtraction) rule to start.

Therefore you'd work out all task contained in brackets first, ie:

-> (0.120) (0.08206)(296.15) ÷ (0.30263)

(Note- all i did was to rewrite 8.206 x 10 ^-2 as a decimal not in standard form)

Then do all multiplications, ie:

-> 2.91624828 ÷ 0.30263

Then divide:

-> 2.91624828 ÷ 0.30263= 9. 6363

Since you didnt state the number of significant digits required, I'm just going to leave it at 5.

Here your task simply is to get y  by itself.

start by removing any value on the same side of the  equation as y:

ie. 4x - 9y =20 (bring 4x on the other side of the equation by subtracting 4x from both sides)

-> 4x- 4x -9y= 20- 4x which results in:

-> -9y= 20- 4x

Now since we are solving for y and not -9y, we bring the -9 on the other side of the equation by dividing both sides by -9, like:

-> -9y/ -9= (20-4x) / -9

which is:

-> y= (20-4x) / -9

 therefore your answer is

y= (20 - 4x) / -9

Step 1: 798/ 8= 99.75

Step 2: 99.75 * 41 = 4089.75

The first significant figure is the first non-zero digit in a number. Therefore the first significant figure in 4089.75 is 4.

If the number following the value that you are rounding to (in this case, the first significant figure ie 4) is greater than or equal to 5, round up the value, ie add 1 to the number. Otherwise round down to the nearest whole number.

Since the number following the significant digit, 4, is zero we therefore round down the number.

Resulting in:

4000.

Therefore, your answer is 4000

Ok, so:

-13 / -10= 1.3

Because a negative divided by a negative results in a positive number

Well the value of e is 2.7182818284590452.

Therefore 2e= 2 (2.7182818284590452)

which equates to:

5.4365636569180905

Yes.

The greatest common factor of two numbers is the highest factor (biggest number) that can divide both numbers without leaving a remainder.

Therefore, by listing all the factors of 16 and 42 you'll see that:

16= 1, 2, 8, 16

42= 1, 2, 3, 6, 7, 14, 21, 42

So therefore, from the above listing you that the highest number that can divide both numbers without leaving a remainder is 2.

It cannot be 16, because as you can see 16 is not a factor of 42 and it cannot be greater that 16 because that factor must be able is divide a number without leaving a remainder (so anything greater than 16 gives a decimal). So the factor has to be less than 16.

Hope that helps.

What do you mean?

The ratio of nuts to dried fruit is 30: 31 and you know the snack contains 480g of nuts. Therefore you can create a proportion (an equation where 2 ratios are equivalent) as follows:

And then solve for the unknown p (which is the amount of fruits in grams), like:

30    = 31

480  = p

cross multiplication results in: 30p = 31 x 480

which equates to:    30p = 14880

solving for p gives: 30p / 30= 14880/ 30 (that is divide both sides by the multiplier of p, to simply get p by itself)

which equates to: p= 496

Therefore, there are 496g of dried fruit in that snack.

To get the total weight of the bar simply add the 480g of nuts and the 496g of fruits

giving you a total weight of: 480+496= 976g
