Ms. Leong owned an ice cream store and had chocolate and vanilla ice cream for sale. She sold 3/4 of the chocolate ice cream and 1/2 of the vanilla ice cream. If she had 20 scoops of chocolate ice cream and 30 scoops of vanilla ice cream left, how many scoops of ice cream did Ms. Leong have altogether at first?

Answers

Answer: 140 scoops.

Step-by-step explanation:

We know that she sold 3/4 of the chocolate ice cream and 1/2 of the vanilla ice cream. She originally had 20 scoops of chocolate and 30 of vanilla left.

so those 20 scoops of chocolate are 1/4 of the total amount that she had before, then the total amount is equal to 4 times 20 scoops = 80 scoops of chocolate.

We also know that 30 scoops of vanilla are one half of the initial number, so the initial number must be equal to two times 30 scoops = 60 scoops.

Now, adding those numbers we have 60 + 80 = 140 scoops in total at the beginning of the day.
The answer is 140 scoops of ice cream total .

(10 points)A certain regular polygon has sides of length 10 cm; its apothem is 12.1 cm. The polygon’s area is 484 cm². How many sides does the polygon have

Answers

There is a mathematical formula which relates these quantities, given by:

A= (P* a)/(2)

Using this, we have:

A= (P* a)/(2) \n 484= ((10n)* 12.1 )/(2) \n \boxed {n=8}

Gary has $250.00 for school supplies. He spends twice as much money on books as hedoes on cleaning supplies. After he pays the cashier, he has $70 left. How much did he

If you divided 48 objects into sets of 7, how many sets of 7 could you make, and how many are left over?

Answers

Answer:

6

Step-by-step explanation:

No. objects in one set = 7

Let there be n set

Then, No. objects in n set = 7*n = 7n

Given that total  no of objects are 48

Thus,

7n = 48

n = 48/7 = (42+6)/7 = 42/7 + 6/7 = 6 + 6/7

n = 6 + 6/7

Thus, there will be 6 set which has 7 objects. fraction means one set is fraction 6/7 but set cannot be in fraction hence negating it.

Now, total objects in 6 sets = 6*7 = 42.

No. of objects left = 48 - 6 = 6
