It took each student 30 minutes to set up the puppet show and twice as long to put everything away. The show was open for 3 hours. How much time did each student spend on this event?
Answers
Answer:
4 and 1/2 hours or 270 minutes
Step-by-step explanation:
Each student spend 30 minutes to set up the puppet show.
+30
They spent twice as long to put everything away.
+30 +30
Current total: 90 minutes
The show was open for three hours
+180 (60 minutes in an hour x 3 hours)
Current total: 270
Total: 270 minutes
OR
Divide 270 by 60 minutes in an hour, which would be 4.5 hours.
Answer: 1 hour and 30
Step-by-step explanation:
First, you multiply 30 minutes x2 and get 60. 60 minutes is an hour so now you have an hour. Then you add 30 minutes to that and get 1 hour and 30 minutes. Then, you subtract 3 hours minus 1 hour, and 30 minutes and get 1 hour and 30 minutes.
The function h(t)=-16t^2+75t+80 models the height in feet, h, of a ball as it is thrown into the
air at time, t, in seconds. At which of the following times will the ball be 124 feet above the
ground?
Answers
Answer:
[tex]t = 4\\[/tex]
or
[tex]t=0.6875[/tex]
Step-by-step explanation:
[tex]124 = -16t^2+75t+80\\-16t^2+75t-44=0[/tex]
Solving for t using the quadratic formula we get:
[tex]t = 4\\[/tex]
or
[tex]t=0.6875[/tex]
The times taken by the ball to be 24 feet above the ground is t = 4 and t = 0.68 seconds.
What is meaning of the term function?an expression, rule, or law defining a connection between one variable (a independent variable) and the other (the dependent variable). Functions are common in mathematics and are required for the formulation of actual relationships with in sciences.The function given for the height of the ball thrown is;
h(t) = -16t^2+75t+80
In which, h is the height in feet,
t, is the time till ball is in air( in seconds. )
When height h = 124 feet.
Time t = ?
Put h = 124 in the given equation.
124 = -16t^2+75t+80
On solving.
-16t^2+75t-44 = 0.
16t^2 - 75t + 44 = 0.
Solve the quadratic equation by the quadratic formula,
t = 4 and t = 0.68 seconds.
Thus, the times taken by the ball to be 24 feet above the ground is t = 4 and t = 0.68 seconds.

Answers
Hint take 880-250
Answer:
Krystal collected 315 pop-can tabs while Natasha collected 565 pop-can tabs.
Step-by-step explanation:
Let x be number of pop-can tabs Krystal collected
Krystal: x
Natasha: x + 250
x + x + 250 = 880
2x = 880 - 250
2x = 630
x = 315
Krystal: 315 pop-can tabs
Natasha: 315+250 = 565 pop-can tabs

A charter fishing boat sold a total of 50 tickets for its two trips yesterday,
There were 19 adults and 7 children on the morning trip. There were 24 adults on the evening trip.
The probability that a randomly selected ticket holder from yesterday is a child or was on the evening trip is
%.
Answers
The probability that a randomly selected ticket holder from yesterday is a child or was on the evening trip is 0.62 or 62%.
To calculate the probability that a randomly selected ticket holder from yesterday is a child or was on the evening trip, we will use the formula: $P(\text{Child or Evening Trip}) = P(\text{Child}) + P(\text{Evening Trip}) - P(\text{Child and Evening Trip})$.We are given that there were 7 children on the morning trip and 24 adults on the evening trip.
Therefore, the number of children who were on the evening trip is 0. Hence, $P(\text{Evening Trip}) = 24/50 = 0.48$.
Similarly, the number of children who were not on the evening trip is 7, while the number of adults who were not on the evening trip is $50 - (7 + 24) = 19$. Hence, $P(\text{Child}) = 7/50 = 0.14$.
Since no child was on the evening trip, $P(\text{Child and Evening Trip}) = 0$.
Substituting these values in the formula above, we get: $P(\text{Child or Evening Trip}) = 0.14 + 0.48 - 0 = 0.62$
Therefore, the probability that a randomly selected ticket holder from yesterday is a child or was on the evening trip is 0.62 or 62%.
