7hours to, mow 14 lawns rate= unit rate=

Unit rate = 2 lawns/hour

Step-by-step explanation:

Given 7 hours to mow 14 lawns.

We have to calculate the unit rate to mow the lawn.

Since in 7 hours number of lawns mowed = 14

Therefore, in 1 hours the number of lawns mowed =

                                                                                   = 2 lawns

In one hour 2 lawns.

Unit rate = 2 lawns/hour

step-by-step explanation:

ask goog great chance of finding the solution there

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
