Stephanie can type around 70 words per minute. She has less than a week to type her final research paper. If the paper has to be
Lana71 [14]
The answer is 1.25 hours.

STEP 1.
Each page has about 350 words:    1 page - 350 words
15 pages is x words:                         15 pages - x words
1 : 350 = 15 : x
x = 15 * 350 : 1 = 5250

So, she has to type at least 5250 words.

STEP 2:
<span>Stephanie can type around 70 words per minute:     70 words - 1 minute
x words in 1 hour = 60 minute:                                        x words - 60 minute

70 : 1 = x : 60
x = 70 * 60 : 1 = 4200

So, she types around 4200 words per hour.


STEP 3:
Now we have:
</span>- she has to type at least 5250 words
- she types around 4200 words per hour

5250 : x = 4200 : 1
x = 5250 * 1 : 4200 = 1.25 hours

Answer:

∠ 1 = 99°, ∠ 2 = 81°, ∠ 4 = 81°

Step-by-step explanation:

∠ 1 and ∠ 3 are vertical angles and are congruent, then

∠ 1 = 99°

∠ 1 and ∠ 2 are adjacent angles and sum to 180° , so

∠ 2 = 180° - 99° = 81°

∠ 2 and ∠ 4 are vertical angles and are congruent, so

∠ 4 = 81°

Choose the equation below that represents the line that passes through the point (7, -2) and has a slope of -3
Ray Of Light [21]

Answer:

B

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 3 and (a, b) = (7, - 2 ), thus

y - (- 2) = - 3(x - 7) , that is

y + 2 = - 3(x - 7) → B
