Answer 1

Answer:

You want to leave a 15% tip on a meal that cost $65.00.

First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.

Second, you need to find out what 15% of your $65.00 meal cost is.This is always done by multiplying 0.15 by $65.00, or

0.15 x $65.00=$9.75.

So, the amount of tip you are going to leave is $9.75.

This makes the total cost of your meal (to write on your charge slip or other payment)

$65.00 + $9.75 = $74.75.

Answer 2

Answer: A: y=50x+75
EXP: The x value 0 is at 75, making that the y-intercept. Rise/run for rise 1 -> 2 is up 50, making slope 50(x). Put it together giving you y=50x+75

Help me im having trouble on slopes

Answers

Answer:

The slope-intercept form of an equation looks like this: y=mx+b

The m stands for the slope and the b stands for the y-intercept.

We need two points from the line to write out this equation.

For example (-2,0) and (1,2)

Now that we have the slope, we can plug it into our equation: y= 2/3x + b

To get b, our y-intercept, we just need to plug in one of the points found and solve. For example (-2,0)

Now that we have both our m and b values, we can plug them in to get our equation: y=2/3x + 4/3

Step-by-step explanation:

$m= (y1-y2)/(x1-x2) = (0-2)/(-2-1)$

$m=(-2)/(-3) = (2)/(3)$

$0=(2)/(3)(-2)+b$

$0=-(4)/(3)+b\n 0+(4)/(3)=-(4)/(3)+(4)/(3)+b\n 0+(4)/(3)=b\n (0*3)/(3)+(4)/(3)=b\n (4)/(3)=b$

Answers

Answer:

D. 3x-5

Step-by-step explanation:

We have been given an polynomial $f(x)=3x^3-5x^2-12x+20$ and we are asked to choose the correct option that represents the factor of our given polynomial according to the rational root theorem.

First of all we will factor our polynomial.

$f(x)=x^2(3x-5)-4(3x-5)$

$f(x)=(x^2-4)(3x-5)$

$f(x)=(x+2)(x-2)(3x-5)$

Therefore, (3x-5) will be a factor of our given polynomial and option D is the correct choice.

A law office is installing new file cabinets. Each file drawer can hold records for 50 clients, and each cabinet has 5 drawers. If the office has 600 clients, how many cabinets should be ordered to store the existing files

Answers

Given:
Each cabinet has 5 drawers.
Each drawer can hold records for 50 clients.

Now,
Each cabinet can hold records for (50 × 5) clients
= 250 clients

Now,
Using unitary method,
250 clients records can be held up in 1 file cabinet.
1 client records can be held up in (1 / 250) file cabinet
600 client records can be held up in (1 / 250) × 600 file cabinet
= 2.4

So, we need 3 file cabinets...cause we cant't get 2.4 file cabinet

1 drawer= 50 clients
I used ratio and proportion first

1 drawer/50 clients= x drawers/600 clients
cross multiply
50x= 600
x= 12 drawers
12 drawers/5 per cabinet=
2/25 or 2.4
need to order 3 cabinets

hope this helps
