Answer:

B - 600 words in 12 minutes

Step-by-step explanation:

So most of this has to do with division. So let's look at answer one

320 words in 8 mins

320/8 = 40 words per minute.

600 words in 12 minutes

600/12 = 50 words per minute

350 words in 8 minutes

350/8 = 35 words per minute

And finally, 225 words in 5 minutes

225/5 = 45 words per minute. Thus, the answer is B

Answer:

The distance between A and B is 8.5 after rounded to the nearest tenth

Step-by-step explanation:

The formula you always use for distance between points is as pictured.

Point A is (-6, 4), this is x1 and y1

Point B is (2, 1), this is x2 and y2

(2-[-6])^2 + (1-4)^2

since 2 negatives make a positive, 2 - -6 = 8

1 - 4 = -3

This makes 8 squared and -3 squared

8x8 = 64

-3x-3 = 9

64 + 9 = 73

the square root of 73 = 8.544003745

After rounding to the nearest tenth, it is 8.5

I hope this helps you! Good luck :)

Manny and Susan have an egg carton full of eggs to use for their science project.
scoray [572]

Answer:

5/6

Step-by-step explanation:

1/3 + 1/2 is a simple addition fraction problem.

You'd find the LCM (lowest common denominator) which is 6. First, we'll take 1/3 which the denominator becomes 6. You see one side has been basically multiplied by 2, so you'd do it to both sides, giving us 2/6. Next, we do the same thing with 1/2. 2 -> 6 1 -> 3. 3/6. So finally, we have 3/6 + 2/6, which is 5/6.

Find the measure of angle XAZ in the figure below.
Bess [88]

Answer:

m∠XAZ = 40°

Step-by-step explanation:

Since ∠YAU, ∠YAZ and ∠XAZ are the angles based at a point on a straight line, and the sum of the all angles on a line is 180°.

Therefore, m∠YAU + m∠YAZ + m∠XAZ = 180°

50° + 90° + m∠XAZ = 180°

m∠XAZ = 180° - 140°

             = 40°

Therefore, measure of angle XAZ is 40°.
