Answer:

Answer:

54 chaperones

Step-by-step explanation:

The basic idea behind this kind of question is that you want to keep the proportions equal. When there are 11 students, there are 2 chaperones. If there are now 297 students, how many chaperones must there be keep the proportions equal?

When answering this sort of question, you should construct an equation in which the basic ratio is equal to the proportions you're interested in. In this case:

2 chaperones / 11 students = X chaperones / 297 students

To find the value of X, you then cross-multiply and solve for X.

Cross-multiplying means that you multiply the numerator (top) on one side by the denominator (bottom) on the other, and vice versa.

Here,

2 chaperones x 297 students = 11 students x X chaperones

You then solve for X.

First, multiply the left side:

594 = 11X

Now, divide 594 / 11 to solve for X.

X = 54.

Because X stood for the number of chaperones, the answer is 54 chaperones.

Determine the x- and y- intercepts for the graph defined by the given equation. y = x + 8

a. x-intercept is (0, 8)

y-intercept is ( -8, 0)

c. x-intercept is ( -8, 0)

y-intercept is (0, 8)

b. x-intercept is (0, -8)

y-intercept is ( 8, 0)

d. x-intercept is ( 8, 0)

y-intercept is (0, -8)

The x-intercept is a point where a line touches or crosses the x-axis thus the x-intercept and y-intercept for y = x + 8 will be (-8,0) and (0,8) respectively thus option (B) is correct.

What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.

For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.

As per the given function,

y = x + 8

At x = 0

y = 8 so (0,8) will be the y-intercept.

At y = 0

0 = x + 8

x = -8 so (-8,0) will be the x-intercept.

Hence "The x-intercept is a point where a line touches or crosses the x-axis thus the x-intercept and y-intercept for y = x + 8 will be (-8,0) and (0,8).

Please help me with this.A rectangular field is 65

meters wide and

105

meters long.

Give the length and width of another rectangular field that has the same perimeter but a smaller area.

First, let's get the perimeter of the rectangle:

Then, let's get the area of the bigger one:

Then let's try using a rectangle with a smaller ratio:

Then:

If you used a square:

There you have it. A rectangle with a smaller area with the same perimeter.

What does it show? The smaller the difference you get from width and length, the larger the area is.

Then, let's get the area of the bigger one:

Then let's try using a rectangle with a smaller ratio:

Then:

If you used a square:

There you have it. A rectangle with a smaller area with the same perimeter.

What does it show? The smaller the difference you get from width and length, the larger the area is.

Well the L and the W could be 75 and 95

Because 75 + 75 + 95 + 95= 340

And 75 x 95= 7125

Same Perimeter, different Area

Glad to Help!

Because 75 + 75 + 95 + 95= 340

And 75 x 95= 7125

Same Perimeter, different Area

COLLEGE

A shirt is on sale with a 25% discount. The original price of the shirt was $28. Will Wayne have enough money to buy the shirt if he has $22?

25% of 28 is 7 (28 x 0.25)

28 - 7 = 21

yes he would have enough money

28 - 7 = 21

yes he would have enough money

Paul and his friends average their test grades and find that the average is 95 the teacher announces that the average grade of all her classes is 83 why are the average so different

Answer: The test scores are different because Paul and his friend only averaged his and his friends grades, while the teacher averaged the whole classes grades.

If LN=54 and LM=31, find MN

The value of the segment MN is 23

LN = 54

LM = 31

MN =?

LN = LM + MN

54 = 31 + MN

Subtract 31 from both sides

54 - 31 = 31 + MN - 31

23 = MN

THE value of the segment MN is 23.

In this item, it is unfortunate that a figure, drawing, or illustration is not given. To be able to answer this, it is assumed that these segments are collinear. Points L, M, and N are collinear, and that L lies between MN.

The length of the whole segment MN is the sum of the length of the subsegments, LN and LM. This can be mathematically expressed,

LN + LM = MN

We are given with the lengths of the smalller segments and substituting the known values,

MN = 54 + 31

MN = 85

ANSWER: MN = 85
