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

HELP WILL GIVE 15 POINTS <br>what is the range of this function and pls explain​
Nataly [62]

Answer:

f(x)\geq -2

Step-by-step explanation:

Range corresponds to the values of y on the y-axis. If we see the graph the minimum value of the y-coordinate is -2 and then it tends to increase from it. We do not know till where the y values will increase in the figure it shows 6 but it's still actually increasing we keep on tracing the graph but the minimum value will always remain the same which is -2 . So we can say that the range of the function is

f(x)\geq -2\\

Where f(x) is the function and since the values of y on the y-axis increase from -2 we can say that the function has the range of values greater than or equal to -2

PLEASE HELP ME <br> I WILL MARK BRAINLIST!!!!
elixir [45]

Answer: A

Step-by-step explanation: The slope of perpendicular lines is opposite reciprocal. In this case the slope would be 4/3. Plug in for x and y, you get -7 for b.

  • y = mx +b
  • 9 = 4/3 (12) + b
  • 9 = 16 + b
  • -7 = b

Rewrite the equation --> y = 4/3x - 7

Ben used 10 1/2 gallons to drive 4 3/4 hours. How many gallons did Ben use in 1 hour?
Kryger [21]

Answer:

About 2.2 gallons

Step-by-step explanation:

Create the following proportion:

\frac{10.5}{4.75} = \frac{x}{1}

Cross multiply.

10.5 x 1 = 10.5

4.75 x X = 4.75x

4.75x = 10.5

Divide both sides by 4.75x.

10.5/4.75 = 2.2
