Answer 1

for mia and ethan they actually have the same ratio if you do 21/3 and then 28/4 they both have the same ratio: 7

Answer 2

For Olivia and Jacob, if we make it so each ratio has 15 girls, we can see that Jacobs class has a 12:15 boy-girl ratio while Olivia only has a 9:15 boy-girl ratio. This means that Jacob has a higher boy to girl ratio.

find an equation of the line that has a y intercept of 5 and is perpendicular to the graph of the line 4x+3y=8.

Answers

Answer:

3x-x+2=4

Step-by-step explanation:

You replace y in the problem with 5 so you have 4x+3*5=8 then you multiply 3*5 and 15 then rewrite your problem so it looks like 4x+15=8 then add 15 to the side with the 8 so it looks like 4x=23 then divide 23 by 4 and you get x.

Answer:

y = 3/4x + 5

-3x + 4y = 20

Step-by-step explanation:

In order to write this equation, you need the slope and y-intercept (I'll answer in slope-intercept form and standard form)

First change that standard form equation to slope-intercept form:

1. 4x + 3y = 8

2. 3y = -4x + 8

3. y = -4/3x + 8/3

Step 1 is given.

In step 2, 4x was subtracted from both sides.

In step 3, both sides were divided by 3.

Slope-intercept form:

y = mx + b

m is the slope and b is the y-intercept.

m = 3/4; the slope of a line perpendicular to another line is the negative reciprocal of the other line's slope (ex: line's slope is 1/4; a line perpendicular to it has a slope of -4, the negative reciprocal)

b = 5; the y-intercept was stated in the problem

Now, you put it together: y = 3/4x + 5

Standard form:

You can just change the slope intercept form back into standard form by moving the numbers around a bit:

1. y = 3/4x + 5

2. -3/4x + y = 5

3. -3x + 4y = 20

Step 1 is given.

In step 2, 3/4x was subtracted from both sides of the equation.

In step 3, both sides were multiplied by 4 so that the equation could have nice whole numbers. (this step is optional, I just think it's easier to read this way)

There is always one front desk clerk on duty at all times, 24/7, and all of the front desk clerks make $8.00 an hour.The housekeeping staff is also paid $8.00 an hour, but they are paid for the number of hours that it takes them to clean the rooms in the hotel. Each room takes 30 minutes to clean, but if a room has not been used the night before, it does not have to be cleaned, so the housekeeping staff work fewer hours on days when the hotel is not as full.The hotel calculates its profitability on a per-room basis, since they have some costs that vary with the number of rooms that are occupied on a particular night.
