A local gym instructor has a course load that allows her to teach eight classes. At an interest meeting, 8 people wanted high-‐

Answer:

The final curse load of the local gym instructor is this:

High-‐impact aerobics = 1

Low-‐impact aerobics = 4

Jazzercise = 1

Step exercise = 2

Step-by-step explanation:

1. Let's apportion the class load using the Hamilton method

Number of classes the local gym instructor can teach = 8

Total number of students that want to take a class = 114 (8 people wanted high-‐impact aerobics, 64 wanted low-‐impact aerobics, 11 wanted jazzercise, and 31 wanted step exercise)

Standard divisor = 114/8 = 14.25

Now, we can apportion the students in in Standard quotas, this way:

High-‐impact aerobics = 8/14.25 = 0.5614

Low-‐impact aerobics = 64/14.25 = 4.49

Jazzercise = 11/14.25 = 0.7719

Step exercise = 31/14.25 = 2.1754

Now, we find the Minimum quota, just considering the whole number and don't taking into account the decimals, this way:

High-‐impact aerobics = 0

Low-‐impact aerobics = 4

Jazzercise = 0

Step exercise = 2

As we can see we have 6 classes and there are 2 still pending. Those 2 goes to the classes with the highest decimal portion, in this case, Jazzercise .7719 and High-‐impact aerobics with .5614.

The final course load is this:

High-‐impact aerobics = 1

Low-‐impact aerobics = 4

Jazzercise = 1

Step exercise = 2

jodi walks 35 minutes a day if she walks for 240 days ,how many minutes altogether does jodi walk ??????

Ann [662]

To answer that question, you need to multiply 35 minutes × 240 days.

So:
35
× 240
_________
8400 minutes,

So Jodi walked a total of 8400 minutes

I hope this helped :)

3x + 2 ≤ 14 -5 + 2x > 15 * -2x + 4 ≥ 18 HaLp i don't gets

Answer:

x ≤ 4
x > 10
x ≤ -7

Step-by-step explanation:

We're guessing you want to solve for x in each case. You do this in basically the same way you would solve an equation.

1. 3x +2 ≤ 14

3x ≤ 12 . . . . . subtract 2

x ≤ 4 . . . . . . . divide by 3

2. -5 +2x > 15

2x > 20 . . . . . . add 5

x > 10 . . . . . . . . divide by 2

3. -2x +4 ≥ 18

4 ≥ 18 +2x . . . . . add 2x

-14 ≥ 2x . . . . . . . subtract 18

-7 ≥ x . . . . . . . . . divide by 2

Additional comment

The statement above that the same methods for solving apply to both equations and inequalities has an exception. The exception is that some operations reverse the order of numbers, so make the inequality symbol reverse. The usual operations we're concerned with are multiplication and division by a negative number: -2 < -1; 2 > 1, for example. There are other such operations, but they tend to be used more rarely for inequalities.

You will note that we avoided division by -2 in the solution of the third inequality by adding 2x to both sides, effectively giving the variable term a positive coefficient. You will notice that also changes its relation to the inequality symbol, just as if we had left the term where it was and reversed the symbol: -2x ≥ 14 ⇔ -14 ≥ 2x ⇔ x ≤ -7 ⇔ -7 ≥ x
