Answer:

Answer:

1. a ≥ -3 and a ≤ 3

I am assuming you mean to have an = sign as well

Step-by-step explanation:

|a| < =3

we get two solutions, one positive and one negative

remember to flip the inequality for the negative

a<=3 and a >= -3

How many ways are there to arrange five French club members for a yearbook photo if the president and vice president must be seated in front with the other three members behind them?

Answers

Since the president and the vice president must be seated in the front, that's two ways already; p-vp, vp-p.

Three other member, let's say their names are Bill, Joe, and Nate.
b-j-n, j-b-n, n-b-j, b-n-j, j-n-b, n-j-b.

6 different combinations.

Multiply 6 by 2,
6 x 2 = 12.

There are 12 different ways.

I just want to see if my answer is correct, I haven't done volume in a long time!

Mr. Hoya brought 5 watermelons from his grocery store. The watermelons weighed 8 1/4 pound, 9 1/4 pound, 8 7/8 pound, 9 5/8 pound, and 10 3/4 pound. At the party 153 people each ate 1/4 pound serving of watermelon. Was the amount of less than or greater than 8 4/8 or 1/2 pounds? Explain how to solve the problem. Then solve it.

Answers

the amount of watermelon consumed was greater than 8 1/2 pounds.

To determine if the amount of watermelon consumed was less than or greater than 8 1/2 pounds, we need to find the total weight of the watermelons Mr. Hoya brought and then subtract the total amount consumed by the 153 people.

1. Find the total weight of the watermelons:

Total weight = 8 1/4 + 9 1/4 + 8 7/8 + 9 5/8 + 10 3/4

2. Convert all the fractions to a common denominator:

Total weight = (33/4) + (37/4) + (35/4) + (39/4) + (43/4)

3. Add the fractions:

Total weight = (33 + 37 + 35 + 39 + 43) / 4

4. Find the sum:

Total weight = 187 / 4

Now, we'll find the total amount consumed by 153 people:

Total amount consumed = 153 * 1/4

Now, we can compare the total amount consumed to 8 1/2 pounds:

8 1/2 = 17/2 = 34/4

Now, let's compare the values:

Total amount consumed = 153 * 1/4 = 153/4 ≈ 38.25

8 1/2 pounds = 34/4 = 8.5

The total amount consumed (38.25) is greater than 8 1/2 pounds (8.5). Therefore, the amount of watermelon consumed was greater than 8 1/2 pounds.

First add all the watermelon weights together (to add the fourths and the eighths multiply the fourths by 2 (1/4x2=2/8) and add the numerators). Then multiply the number of people (153) by how much they each ate (1/4). Then subtract the total amount eaten (38 1/4) from the total weight (46 3/4) and compare that with 8 1/2... The left overs are actually equal to 8 1/2 pounds :)
