The table represents the total miles traveled, y, after a number of hours, x. Hours, x Miles, y 2.5 150 4.0 240 5.5 330 7.0 420

maw [93]

(2.5,150)(4,240)
slope = (240 - 150) / (4 - 2.5) = 90 / 1.5 = 60

y = mx + b
slope(m) = 60
(4,240)...x = 4 and y = 240
now we sub and find b, the y int
240 = 60(4) + b
240 = 240 + b
240 - 240 = b
0 = b

so ur equation is : y = 60x + 0 which is written as : y = 60x <==

David made a class banner out of a large rectangular piece of paper. He

spin [16.1K]

<u>Given:</u>

A triangular piece is cut out of a rectangular piece of paper to make the class banner.

<u>To find:</u>

The area of the class banner.

<u>Solution:</u>

The rectangular piece of paper is 14 inches long and $5+3=8$ inches wide.

From the given diagram, the triangle has a base length of the same 8 inches and has a height of $14-11=3$ inches long.

To determine the area of the banner, we subtract the area of the triangle from the area of the rectangle.

The area of a triangle $= \frac{1}{2} (b)(h).$

The area of the triangle $= \frac{1}{2} (8)(3) = 12$ square inches.

The area of a rectangle $= (l)(w).$

The area of the rectangle $= (14)(8)= 112$ square inches.

The area of the class banner $= 112-12=100$ square inches.

So the banner has an area of 100 square inches which is the first option.

What would this question look like after we change the mixed number to improper & use KCF to rewrite the question?

iris [78.8K]

Answer:

The question $3\frac{1}{2}\div\frac{1}{3}$ after change the mixed number to improper & using KCF will become : $\mathbf{=\frac{7}{2}\times \frac{3}{1}}$

Option B is correct option.

Step-by-step explanation:

We need to change the mixed number to improper & use KCF to rewrite the question.

The expression is: $3\frac{1}{2}\div\frac{1}{3}$

First converting mixed fraction into improper fraction

Multiply whole number with the denominator i,e (3*2=6) now add the numerator i.e (6+1) = 7/2

Solving:

$3\frac{1}{2}\div\frac{1}{3}\\=\frac{7}{2}\div\frac{1}{3}$

Using KCF

KCF stands fro Keep it, Change it, Flip it.

It is used when division sign is converted to multiplication the term (1/3) is reversed to (3/1)

So, our expression will be

$=\frac{7}{2}\times \frac{3}{1}$

So, The question $3\frac{1}{2}\div\frac{1}{3}$ after change the mixed number to improper & using KCF will become : $\mathbf{=\frac{7}{2}\times \frac{3}{1}}$

Option B is correct option.
