40 words

Step-by-step explanation:

120 words/3 minutes is the same as 120 divided by 3

so, you divide 120 by 30 and you get 40 words per minute

Step-by-step explanation:

We are going to make a questioning. Look:

If in 3 minutes she can type 120 word

In    1 min  how many will she type X

We adopt X as a thing witch we don't know. This forms a Rule of three. It happens when we have got 3 values but miss us 1 yet.

Generraly you'll sort the values by type. In this case, I put minutes under minute and words under words.

A Fast way to solve is: multiply where there is not an incognt (1*120) and divide by what left (3)

So:

1*120=120

Divided by 3 (120/3) it's equals 40 words per minute.

Good studies!

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
