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

Answer:
How long does it take the students in my class to travel to school?
Step-by-step explanation:
A statistical question is one that can be answered by collecting data and where there will be variability in that data.
The number of students who do not bring lunch will be 210.
The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
Lunch A survey showed that 30% of students bring their lunch to school. The survey polled 300 students. Then the percentage of students who do not bring lunch will be
⇒ 100% - 30%
⇒ 70%
Let x be the number of students who do not bring lunch. Then we have
x = 70% of 300
x = 0.70 × 300
x = 210
The number of students who do not bring lunch will be 210.
