the rectangular projection screen in the school auditorium is 5 times as long and 5 times as wide as the rectangular screen in the library. the screen in the library is 4 feet long with a perimeter of 14 feet.


what is the perimeter of the screen in the auditorium?

Answers

Answer 1

Answer:

Library: length 4, width 3 = 4(2)+3(2)=14

Take the length and width and multiply them by 5.

4*5=20 and 3*5=15

20(2)+15(2)= 70

The perimeter of the auditorium screen is 70.

Step-by-step explanation:

Answer 2
The answer is 70 ft.

We know that the perimeter of the screen in the library is 14 ft.

The formula for perimeter is length+width+length+width=perimeter

We are already given the length so it will be 4+w+4+w=14

4+4 equals 8 and 14-8 equals 6. We then divide 6 by 2 and we have the width.

Length: 4 ft.
Width: 3 ft.

The problem says the auditorium screen is 5 times bigger so we multiply

4 times 5 and 3 times 5

We now have 20 and 15

The problem asks for perimeter

There are four sides in a rectangle so it will be 20+15+20+15 equals 70 ft.

Answer: output = -1n + 7 or  -n + 7

n can represent any number.

Step-by-step explanation:  using the slope-intercept form y = mx + b

y is the output. x is any input.  m is the slope.  b is the constant.

Calculate the slope:  rise ÷ run  

You see all the inputs in the chart are going up by 1. This is the run +1

You see all the outputs going down by 1.   This is the rise:  -1

So the slope, m,  is rise / run . -1/1 =  -1

To find the constant, use the slope with any pair of inputs and outputs from the chart in place of y and x in the slope-intercept equation.

y = mx + b  becomes   6 = -1(1) + b . Solve for b

6 = -1 + b

6 +1 = -1 +1 + b

7 = b

Now set up the equation that answers the question using the calculated values of m and b.

y = -1(x) + 7 . We can answer the question with this equation rewritten a bit:

Output = -1n + 7

or -n + 7  as 1 is usually implied.

-n+7 this is the answer sis

Answers

Answer:

B i think

Step-by-step explanation:

Juans work is correct because the equation to find cost of each banana is 4b=$2.36

What is Number system?

A number system is defined as a system of writing to express numbers.

Given that the cost of 4 bananas is $2.36

We have to find the cost of each banana.

To find this we have to divide the cost by number of bananas

Divide two point three six by four

Banana is denoted by b

4b=$2.36 is the required equation

Cost of each banana =$2.36/4

=$0.59

Hence, Juans work is correct because the equation to find cost of each banana is 4b=$2.36

I NEED THIS ANSWER BY TUESDAY THE 1ST!!! PLEASE ANSWER!!!

Answers

Answer:

The measure of angle MNP is

m ∠ MNP =  (x - y)/2

Explanation:

The image attached shows the figure corresponding to this question.

The angle MNP, which is also the angle LNP, is formed by the intersection of a secant and a tangent to a circle.

Then, you can use the theorem:

the angle formed by a secant and a tangent to a circle that intersect outside the circle is half the difference of the major arc minus the minor arc.

The major arc formed is identified with the letter x and the minor arc is identified with the letter y. Thus, the measure of the angle MNP is half the difference x - y:

m ∠ MNP = (x - y)/2
