Answer and Step-by-step explanation:

Simply use the Pythagorean Theorem to solve.

The Pythagorean Theorem is used to solve for a side in right triangles.

$A^{2} +B^{2}= C^{2}$

Plug the sides values into the equation.

$A^{2} + 13^2 = 20^2\\\\A^2 + 169 = 400\\\\A^2 = 231\\\\A = 15.1987$ <- This is the answer.

What represents 200 million

sattari [20]

Answer:

200 million represents a very large number and therefore it is not commonly encountered in the history of the people of God. However, is reflected in the number of silver coins annually paid by the vinedressers who farmed King Solomon's vineyards (ie, 1,000 x 1,000 x 200).

10) 25 : 24

11) 24 : 5

12) 36 : 5

13) 7 : 3

14) 15 : 1

Ratio = Number of event 1 : Number of event 2 (in same unit, if necessary)

10

Girls preferring orange juice : Boys preferring orange juice

50 : 48 (Divide by 2 on both sides)

25 : 24

11

Boys preferring orange juice : Boys preferring grapefruit juice

48 : 10 (Divide by 2 on both sides)

24 : 5

Remember :

1 minute = 60 seconds
1 week = 7 days
1 hour = 60 minutes

12

3 minutes : 25 seconds

3 × 60 : 25 (Divide by 5 on both sides)

3 × 12 : 5

36 : 5

13

2 weeks : 6 days

2 × 7 : 6 (Divide by 2 on both sides)

7 : 3

14

5 hours : 20 minutes

5 × 60 : 20 (Divide by 20 on both sides)

PLEASE HELP

Papessa [141]

Answer:

A)3.74

B)17.04

C)61.92

Step-by-step explanation:

The equation of the line of best fit:

$y=3.74x+17.04$

Where x is time in hours

y = midterm score

a)For an increase of one hour in the time spent studying, what is the predicted increase in the midterm score?

General equation y = mx+c

where m is the slope .

On comparing m = 3.74

Slope is the rate of increase per hour

So, For an increase of one hour in the time spent studying, the predicted increase in the midterm score is 3.74

b)What is the predicted midterm score for a student who doesn't spend any time studying?

Substitute x = 0

y=3.74x+17.04

y=3.74(0)+17.04

y=17.04

c)What is the predicted midterm score for a student who studies for 12 hours?

Substitute x = 12

So,y=3.74x+17.04

y=3.74(12)+17.04

y=61.92
