Answer:

A: 85%, 2 $\frac{1}{5}$ , 3.24, $\frac{19}{4}$

B: covert numbers into percent

Step-by-step explanation:

Part A

We have:

$\frac{19}{4}$ , 2 $\frac{1}{5}$ , 85%, 3.24 --> let's convert them into percentages like the 85, to determine which one is greatest/least:

85% --> 85% (already a percent)

$\frac{19}{4}$ --> to convert into percent: (19÷4) x 100 = 475%

2 $\frac{1}{5}$ --> convert first into improper fraction then into percent: (11/5) x 100 = 220%

3.24 --> multiply by 100: 3.24 x 100 = 324%

From least to greatest: 85%, 220%, 324%, 475%

= 85%, 2 $\frac{1}{5}$ , 3.24, $\frac{19}{4}$

Part B:

In part A, to determine the numbers from least to greatest, we rewrote the numbers all into percentage form by first converting into decimal form and then multiplying by 100.

Write an equation of the line below.

Lubov Fominskaja [6]

Answer (assuming it can be in slope-intercept form):

$y = \frac{4}{5} x$

Step-by-step explanation:

1) First, find the slope of the line. Use the slope formula $m = \frac{y_2-y_1 }{x_2-x_1}$ and substitute the x and y values of two points on the line into it. We can see that the line passes through (0,0) and (5,4), so let's use those points for the formula and solve:

$m = \frac{4-0}{5-0} \\m = \frac{4}{5}$

So, the slope is $\frac{4}{5}$ .

2) Next, identify the y-intercept of the line. The y-intercept is the point at which the line intersects the y-axis. We can see that the line intersects the y-axis at (0,0), so that must be the y-intercept.

3) Now, write the equation of the line in slope-intercept form using the $y = mx + b$ format. The number in place of $m$ represents the slope, so substitute $\frac{4}{5}$ in its place. The number in place of $b$ represents the y-intercept, so substitute 0 in its place. This gives the following answer and equation:
