A volleyball coach plans her daily practices to include 10 minutes of stretching, 2/3 of the entire practice scrimmaging, and the remaining practice time working on drills of specific skills. On Wednesday, the coach planned 100 minutes of stretching and scrimmaging. How long, in hours, is the entire practice?

Answers

Answer:

Time for the entire practice is 2.25 or 2 1/4 hours

Step-by-step explanation:

According to the question the volley ball coach daily plan practice includes stretching , scrimmaging and she use the remaining practice time working on drills of specific skills.

let the entire time required for practice = y minutes

Stretching consumes 10 minutes, mathematically

stretching = 10 minutes

scrimmaging = 2/3 × y

Drills of specific skills = y - (2/3 × y) - 10 = 1/3 y - 10 minutes

On Wednesday she had

stretching + scrimmaging = 100 minutes

we all know her stretching daily timing is 10 minutes and scrimmaging timing is 2/3 × y

Therefore,

10 + 2/3 y = 100

100 - 10 = 2/3 y

90 = 2/3 y

multiply both sides by 3

90 × 3 = 2/3 y × 3

270 = 2 y

y = 135 minutes

since the answer is suppose to be in hours

60 minutes = 1 hour

135 minutes = ?

135/60 = 2.25 hours or 2 1/4 hours

Since it is 100 minutes of stretching and scrimmaging, we can subtract the 10 minutes we know is stretching. 90 minutes is equal to 2/3 of the practice then. Divide by 2 and multiply by 3 to get the entire time of the practice or 135 minutes. However, you asked for it in hours, so we can subtract 120 minutes because this is 2 hours. 15 minutes is 1/4 of an hour. So practice took 2&1/4 hours. Hope that helps.

Please help I'm a little confused!Eight is less than or equal to the quotient of a number and negative four.

Answers

I will have "x" represent the unknown number, or you could use a "?", doesn't matter.

$8\leq (x)/(-4)$ [8 is less than or equal to (≤) the quotient (÷) of a number and -4, so the number is being divided by -4]

If you need to solve this, you need to isolate/get the variable "x" by itself in the inequality:

$8\leq (x)/(-4)$ Multiply -4 on both sides to get rid of the fraction and get "x" by itself

$(-4)8\geq (x)/(-4) (-4)$ When you multiply/divide by a negative number, you flip the sign (< >)

-32 ≥ x [-32 is greater than or equal to x, or x is less than or equal to -32]
