15% of 200

25% of 200

35% of 100

30, 50, 35

Step-by-step explanation:

Just ask if you need an explanation.

30; 50; 35

Step-by-step explanation:

To do this we can convert the percentages tofractions

15%->15/100->3/20

25%->25/100->1/4

35%->35/100->7/20

We can just pit the decimal over 100 and simplify it to make the calculations easier. To simplify you just have to divide the numerator and denominator by the same number. x/x is equal to 1 which is why it works. However, x/y does not equal 1.

We can make 200 and 100 into fractions too, to make it easier to understand.

We do this by putting it over 1, since it doesn't change the value of the number.

3/20*200/1

Now the numerators multiply together, and the denominators multiply together. Quick reminder: numerator is on top, and denominator is on the bottom.

So our answer is

600/20

Which is

30.

Now the next one.

1/4*200/1=200/4

Simplify.

50.

Last one:

7/20*100/1=700/20

Simplify.

35.

3 ft

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3
