BD is Geometric Mean

That's mean BD² = 6 × 5 = 30 ⇒ BD = √30

x² = BD² + 6² = 30 + 36 = 66 ⇒ x = √66

y = √55

Answer 2

Answer: 66

2/3 of all your books are fiction. 1/6 of those are historical fiction.

What fraction of all your books are historical fiction?
A.1/9
B.1/18
C.1/3
D.1/2

Answers

Answer:

1//18

Step-by-step explanation:

2/3 * 1/6= 1/18

You first do 2*1

Then 3*6

Answer: A. 1/9

Step-by-step explanation:

to find what fraction of all your books is historical fiction, you would multiply how the fraction of all your books that are fiction by the fraction of fictional books that are historical fiction.

this gives you 2/3 times 1/6.

from there you simply multiply the numerators (2x1=2)

and the denominators (3x6=18)

leaving you with 2/18

but that can be simplified, giving you the final answer of 1/9

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope-Intercept Form: y = mx + b

m - slope b - y-intercept

Step-by-step explanation:

Step 1: Define

Point (4, 15)

Point (-1, -15)

Step 2: Find slope m

Substitute:                    [tex]m=\frac{-15-15}{-1-4}[/tex]Subtract:                       [tex]m=\frac{-30}{-5}[/tex]Divide:                          [tex]m=6[/tex]

Step 3: Find y-intercept b

Define:                    y = 6x + bSubstitute:              -15 = 6(-1) + bMultiply:                  -15 = -6 + bIsolate b:                 -9 = bRewrite:                   b = -9

Step 4: Write linear equation

I just need a run down on how to find a linear equation from two points I'll give Brainiest

Answers

Given the graph of a line, you can determine the equation in two ways, using slope-intercept form, y=mx+b y = m x + b , or point-slope form, y−y1= m(x−x1) y − y 1 = m ( x − x 1 ) . The slope and one point on the line is all that is needed to write the equation of a line.

Answers

Answer:

a. 121

b. 32100

c. 0.2

d. 400

Step-by-step explanation:

a. Quick disclaimer: If there's a decimal point on the divisor, in this case it would be .05, you have to move the decimal point until it has no decimal, in this case .05 would become 5.0 or just 5. The other number also has to have it's decimal point moved as much as the divisor, in this case two times, so it would be from 6.05 to 605. So with this in mind: 605/5 = 121

b. 96.3/.003 = 96300/3 = 32100

c. 0.12/0.6 = 1.2/6 = 0.2

d. 3.2/.008 = 3200/8 = 400

$10 an hour

Step-by-step explanation:

You go to the one hour than go up to where the line is and find out what the number is  

Answer:

Step-by-step explanation:

Ok, so to solve this problem, you need to find the slope of the line. You know this is what you need to find because units for slope is the y-axis units (dollars) divided by the x-axis units (hours), and your answer must be in dollars per hour based on the question. To find your slope, you use the formula (y2-y1)/(x2-x1). Basically, pick any two points on the graph. I will use (2,20) and (4,40). Now, find the change in x (4 - 2, or 2) and the change in y (40 - 20, or 20) and divide the change in y by the change in x (20/2) to get your answer.


Amy has $725 in savings. She plans to save an additional $25 per month. What is the number of additional months Amy will need to save money in order to have exactly $1,000?

A.11

B.29

C.40

D.69

Answers

Answer:

11 months

Step-by-step explanation:

We know that Amy has a saving of $725 which she needs to make it up to $1000 by saving $25 each month.

This means that Amy needs to save $1000 - $725 = $275 more dollars to have exactly $1000 dollars.

If Amy saves $$25 each month, then the number of months that she needs to save money will be = 275 / 25 = 11 months
