The rectangle below has a length of 7 centimeters and a width of 3 centimeters. Three centimeters are subtracted from the length, and c centimeters are added to the width. The area of the new rectangle is 32 square centimeters. What is the value of c?

A. 1 centimeters
B. 3 centimeter
C. 5 centimeters
D. 10 centimeters

Answers

Answer 1

Answer:

C

Step-by-step explanation:

7 - 3 = 4 = Length

3 + c = ? = w

A = 32

32 ÷ 4 = 8 = w

8 - 3 = 5 = number added to width

5 = c

Word explanation:

To find the number added, you have to figure out the length so that you could divide it by area to figure out the width.

So, to do that, you follow what the question said, "Three centimeters are subtracted from the length." = 7 - 3 = l = 4

Then, you move on to figure out the width, so you divide the area by the length = 32 ÷ 4 = 8 = width.

Now that you know the width, you continue to follow what the question said, "C centimeters are added to width."

= 3 (previous width) + c = 8 (new width)

After that, you subtract 8 - 3 to find the amount added to the width and that gives you 5, which is C.

Answer 2

The value of the variable c is 5 centimeters.

What is the area of the rectangle?

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

To determine the number added, we have to figure out the length so that we could divide it by area to figure out the width.

"Three centimeters are subtracted from the length means;

= 7 - 3 = l = 4

Then, move on to figure out the width, so we divide the area by the length

= 32 ÷ 4

= 8  width.

Now that we know the width, continue to follow what the question said, "C centimeters are added to width."

= 3 (previous width) + c = 8 (new width)

After that, subtract 8 - 3 to find the amount added to the width and that gives 5, which is C.

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%.

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.

Step-by-step explanation: when x is 0 y=8 so that gives you the y-intercept. When you subtract 8-6 its 2 which is over 2 which is 2

Answer: y = -2x + 4

Step-by-step explanation:

First, you can find b (the y-intercept) from the coodinates. Where y=0, x=4. This is your y intercept (b).

To find the slope (m), take two points from the graph:

Let's use (2,4) and (3,2). Next, find the difference in the x and y values.

Difference in Y = 4-2 = 2

Difference in X = 2 - 3 = -1

Now we can find the slope by dividing the difference in y values by the difference in x values:

2/-1 = -2 (m = -2)

Now plug the values for b and m into your equation.

y = -2x + 4

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.

The windmill was, in fact, Napoleon's own creation. Why, then, asked somebody, had he spoken so strongly against it? Here Squealer looked very sly. That, he said, was Comrade Napoleon's cunning. He had seemed to oppose the windmill, simply as a maneuver to get rid of Snowball, who was a dangerous character and a bad influence.
