If there are 3 boys for every 4 girls in the choir, how many boys are there if there are 42 students?

1 answer:

3 0

So if there are 3 boys to every 4 girls, and there are 42 boys, the answer would be 42 to 56????? I'm not quite sure, and it's probably wrong, but that's how we learned in my school.

How do you determine if the following scale factor 4/3 would create an enlargement, reduction, or isometric figure?

If the scale factor is greater than one, it will always create an enlargement, so since 4/3= 1 1/3 it’s 1 1/3 the size of the original figure, AKA an enlargement

Step-by-step explanation:

Slope-intercept form is [ y = mx + b ] where m = slope and b = y-intercept. We are already given the slope and y-intercept so m = 2 and b = -4.

y = 2x - 4

Answer: The answer is 280 ft.

Step-by-step explanation:

divide the green area into a triangle and a rectangle so it's easier to calculate. Then find the area of the rectangle by multiplying 14 times 16. That should get you 224. Then, find the area of the tringle by multiplying 14 times 18, times 1/2. That will get you 56. If you add 56 to 224, that gets you 280.

Answer:

The slope of the equation is -3.

Step-by-step explanation:

Given : Mr. Mole's burrow lies 5 meters below the ground. He started digging his way deeper into the ground, descending 3 meters each minute.

To find : What is the slope ?

Solution :

Let x be the number of minutes taken to dig the ground.

He started digging his way deeper into the ground, descending 3 meters each minute i.e. '-3x'

Let y is the total distance travel to dig the ground.

Mr. Mole's burrow lies 5 meters below the ground.

The equation form is $y=-3x-5$

Comparing with general slope form i.e. $y=mx+c$ where m is the slope.

The slope of the equation is -3.
