Answer:

  6 h

Step-by-step explanation:

The bottom number in the table is half the top number. The missing value is 6 (hours).

__

I like to put the variable in the numerator of a proportion. Here, we can write it as ...

  t/12 = 45/90

Multiplying by 12 gives ...

  t = 12(45/90) = 12(1/2) = 6

It will take Darin 6 hours to mow 12 lawns.

the maximum distance D in kilometers that you can see from a height H in meters is given by the formula d equals 3.5 times the s
Irina-Kira [14]
First put the words in an algebraic format or a model. D = 3.5(√H). Now determine what the question is asking. It's height. Plug in the value of D. Distance is 35 km.
35 = 3.5(√H) We want to get H by itself. First thing to get away from it is 3.5. So                      divide 35 by 3.5 And 3.5(√h) by 3.5.
10 = √H        To get rid of √ do the opposite raise to the power of 2
10² = (√H)²   
100 = H 
You must be 100 kilometers above ground to see 35 kilometers
