A sum of money was divided between Riaz ad Ali in the ratio of 3:2. Riaz received the larger share. Write the amount each receiveda) as a fraction
b) as a percentage

Answers

Riaz : Ali
3 : 2

Add the two values; so 3 + 2 is 5

Then 100/5 = 20

So: 20 x 3 = 60
and 20 x 2 = 40

Riaz = 60%
Ali = 40%

Then write 60% and 40% as a fraction:
60% = 3/5 (3 over 5)
40% = 2/5 (2 over 5)

The answers are in bold :)

When is it helpful to round the quotient to the nearest hundredth

Answers

The correct answer is:

It is helpful to round to the hundredths when we are dealing with money.

Explanation:

Our monetary system has dollars and cents, and it takes 100 cents to make a dollar. This means we would have a measurement to the hundredth place for money. If we are dividing and get a quotient that goes past the hundredths place, if it is money, we should round it to the hundredths place.

Given f(x)=(x+5)(x-2), what are the x-intercepts?

Answers

Answer:

The intercepts are -5 and 2

Step-by-step explanation:

Using the zero product property

f(x)=(x+5)(x-2)

0 =(x+5)(x-2)

0 = (x+5)   0=(x-2)

x = -5            x = 2

The intercepts are -5 and 2
