1/4= 3/12 +3/12 =6/12
1/3= 4/12
6/12+4/12=10/12

So, 10/12 of the quiche was not eaten

Out of a salary of $4500. I kept 1/3 as saving. Out of the remaining money. I spend 50% on food and 20% on house rent. How much

Step2247 [10]

Well 1/3 for savings means that you save 1/3*4500 or 1500 dollars.
You then have $3000 left. Of this if you spend 50% on food, you spend 0.5*3000 or 1500 dollars on food.

The school you want to go to has an acceptance rate of 15%. That means that 15% of the students who apply to the school get in.

12,000 Students Applied...

To find the answer, consider that for every 1000 students that apply, 150 students are accepted.

Divide 1800 by 150 and you get 12....which can be translated to 12,000 students

a toy store marks down every toy by 15% in January. How much does a toy cost during January? Use p for the price in December.

satela [25.4K]

A toy cost 0.85p in January.

Step-by-step explanation:

Given,

Mark down in January = 15%

Let,

Price in December = p

Mark down in January = 15% of price in December

Mark down in January = $\frac{15}{100}*p$

Mark down in January = 0.15p

Price of toy in January = Price in December - Mark down

Price of toy in January = p - 0.15p = 0.85p

A toy cost 0.85p in January.

Write a formula that will yield the nth term of the sequence: 3,-2,-7,-12

RUDIKE [14]

Answer:

-5n + 8

Step-by-step explanation:

1. What is the difference?

The sequence goes down by 5. This means that the formula will have -5n in it.

2. Work out the term before the first term.

The first term is 3, and we know that the sequence goes up by 5. So, to get the term before 3 we would add 5.

3 + 5 = 8 Remember, this is positive 8. (+8)

3. Put that term at the end of the equation.

We have -5n already and we just worked out the term before the first one which is positive 8 - so put that at the end of the equation.

-5n + 8 This is our answer!

Just to prove it works:

Substitute: n = term

Lets see if we can get the 3rd term which is -7. (n = 3)

-5(3) + 8

-15 + 8 = -7

See, it works!
