Mathematics
1 answer:
muminat3 years ago
6 0

Answer:

All false.

Step-by-step explanation:

The ratio is 3:4.

For every 3 girls, there are 4 boys.

If a class has 7 people, 3 are girls and 4 are boys.

Hence the fraction of boys is 4/7 and girls are 3/7.

Therefore, a and b are False.

The number of boys in the class cannot be 6. If the number of boys is 6, then the number of girls must be 4.5 to maintain the 3:4 ratio, but there cannot be half a girl. So, c is also false. d) the number of pupils in the class is 12. To maintain a 3:4 ratio, the number of pupils in the class must be in multiples of 7. Hence, d is also false.

Answer:

9000 ft

Step-by-step explanation:

Given: A airplane is ascending at a constant rate of 15 feet per second,

What we need to know: The change in altitude during 10 minutes of flight,

60 seconds = 1 minute

60 × 10

= 600 seconds

600 × 15

= 9000 ft

Therefore there was a 9000 ft change in altitude during the 10 minutes of the flight.

A building has a shadow that is 25 feet long. A person 6 feet tall cast a similar shadow. How long is the person's shadow?
mario62 [17]
Imagine the side of the building is one side to a triangle and the second would be from the top of the building to the point where the shadow ends and the third is from the base of the building to the point where the shadow ends. Just use the pythagoreon theorem to find stuff. I can't solve the problem you gave because you would need the height of the building

What is the greatest common factor of 12хуб + 60xy? — 24x°у? ?
Liula [17]

The greatest common factor is 12xy

Explanation:

The given expression is 12xy^6+60xy

We need to determine the greatest common factor of the given expression.

The greatest common factor of two numbers is the largest number of the two numbers that divides them both.

Hence, from the given expression, let us common out the highest factor that divides the two numbers.

Thus, we have,

12xy^6+60xy=12xy(y^5+5y)

Thus, the largest number that divides both the terms is 12xy

Hence, the greatest common factor of the given expression is 12xy
