Answer:

Step-by-step explanation:The correct answer is:

If you must have the same number of boys and girls in each group, you can have 7 groups.

Explanation:

To do this, we find the Greatest Common Factor (GCF) of 14 and 21. For this, we find the prime factorization of each number:

14 = 2(7)

21 = 3(7)

The only common factor between these two numbers is 7. Thus we can have 7 groups.

(In each group, we would have 14/7 = 2 boys and 21/7 = 3 girls.)

Alladin's Amusement Park has a popular roller coaster ride. There are 2 trains. Each train has 7 cars. Each car holds 16 people.
Nataly [62]

Answer:

224

Step-by-step explanation:

Number of trains in the roller coaster = 2

Number cars in each train = 7

Total number of cars = Number of trains \times Number of cars in each train = 7\times 2 = 14

Number of people in each car = 16

Total number of people in 14 cars = Number of people in one car \times Number of cars = 16 \times 14 = 224

i.e.

Total number of people in the roller coaster in one run = 224

Number of runs made by each train in one hour = 10

Therefore, Total number of people that can ride the roller coaster in one hour can be found by multiplying the number of runs with total number of people in the roller coaster in one run.

224 \times 10 = <em>2240</em>

-4x to the power of 2 y × -3xy to the power of 3
denis23 [38]

- 4x^2y * 3xy^3

multiply the numbers : 4*3 = 12

-12x^2xy^3y

apply exponent rule : x^2x = x^2+1 = x^3

-12x^3y^3y

apply exponent rule again : y^3y = y^1+3 = y^4

answer : -12x^3y^4
