Johanna can type 120 words in 3 minutes. Using the same unit rate, how many words can she type in 10 minutes?

600 words.

Step-by-step explanation:

If Johanna can type 120 words in 3 minutes, and the problem is asking us to find how many words she can type in 10 minutes at the same unit rate, we'll have to start by solving how many words she can type in 1 minute:

Dividing 120 words into 3:

words per minute.

Now that we know how many words Johanna types in one minute (per minute), we can multiply the words per minute by 10 (minutes):

× words in 10 minutes.

_

We can check our work by dividing 600 words into 10 minutes to see if we achieve the same unit rate of 60 words per minute:

words per minute.

Since we have the same unit rate, our answer is correct!

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

its c or d   take a lucky guess my dude
