Answer:

No

Step-by-step explanation:

Belinda babysits her neighborhood's children in the evening every 14 days. Belinda goes to visit her grandmother in the afternoon every 21 days.

If Belinda has both activities planned for today.

The next time Belinda will have both activities on the same day is determined by the Lowest Common Multiples of 21 and 14.

Express each number as a product of its prime factors

21=3 X 7

14 =2 X 7

L.C.M = 2 X 3 X 7 =42

The next time she will have both activities on the same day is 42 days from today. So both activities occurring 30 days from now is impossible.

Compute using long division: 1,234÷68
Kruka [31]

Answer:

Quotient = 18

Remainder = 10

Step-by-step explanation:

1234/68

=> 68 x 1 = 68

=> Take the 4 down

=> 554/68

So, the quotient = 18.

Remainder = 10

If an 8" X 8" square cake serves 8 people, how many 24" X 24" square cakes are needed for a
tigry1 [53]

Answer:

2 24" X 24" square cakes are needed.

Step-by-step explanation:

This question is solved by proportions.

Area of a square:

The area of a square of side l is given by:

A = l^2

8" X 8" square cake serves 8 people

Thus:

A = 8*8 = 64

Area of 64 serves 8 people, so for 1 people, an area of 64/8 = 8 is needed.

144 people

The total area needed is:

A = 144*8 = 1152

How many 24" X 24" square cakes?

24*24 = 576

1 cake - 576

x cakes - 1152

Applying cross multiplication:

1152/576 = 2

2 24" X 24" square cakes are needed.
