2.21 is 2.5% of what

1 answer:

6 0

So first to solve this you divide it by 2.5 to get what 1% is: this would be 0.884.
Then to get 100% of the number you multiply 0.884 by 100. The answer to that is 88.4.
2.21 is 2.5% of 88.4, hope this helps!

Answer:

y = 2/3x + 4

Step-by-step explanation:

Step 1: Find slope

m = (4-0)/(0+6)

m = 2/3

Step 2: Write in y-int (0, 4)

y = 2/3x + 4

I need help with these two

djyliett [7]

Answer:

Part 1) Slope-intercept form

Part 2) The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee

Step-by-step explanation:

Part 1) we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

$y=2.50+2.20x$

This is a linear equation in slope intercept form

where

$m=2.20$

$b=2.50$

Part 2) we have that

x -----> represent the number of miles

y ----> represent the total charge in dollars

The slope is

$m=\$2.20\ per\ mile$ ---> unit rate

The y-intercept is

$b=\$2.50$ ----> initial value or flat fee

therefore

The slope of 2.20 tells me the rate per mile and the y-intercept of 2.50 tells me the flat fee

Points X, Y, and Z are colinear.<br> X<br> What is the slope of YZ in simplest form?

DIA [1.3K]

Based on the calculations, the slope of line YZ in simplest form is equal to 2.

<h3>How to determine the slope of YZ?</h3>

Mathematically, the slope of a straight line can be calculated by using this formula;

$Slope, m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope, m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}$

Since points X, Y, and Z are collinear, we can deduce that the line passes through line Z at 6 units form the origin and 3 units for Y from the origin.

Substituting the parameters into the formula, we have;

$Slope, m = \frac{6\;-\;0}{3\;-\;0}$

Slope, m = 6/3

Slope, m = 2.
