I know it's positive, and I THINK it's non-linear
Length / wingspan
14.8 / 9.8 = 0.5 / x
cross multiply
(14.8)(x) = (9.8)(0.5)
14.8x = 4.9
x = 4.9 / 14.8
x = 0.331 meters....wingspan of model
Answer: it will take them 2 hours to now 7 lawns
Step-by-step explanation:
It takes Hank 40 minutes (2/3 hours) to mow a lawn. This means that his unit rate of working is 1/40
Penny can mow the same size lawn in 30 minutes (1/2 hour). This means that his unit rate of working is 1/30
If they form a small lawn care company, they will be working together and simultaneously at a faster combined rate. Since their rates are additive.
If they finish one lawn in t hours, working together, then their combined working rate for one lawn is 1/t. Therefore
1/40 + 1/30 = 1/t
1/t = 7/120
t = 120/7 = 17.14
They will now one lawn in 17.14 minutes
For 7 lawns, it will take them 17.14 × 7 = 119.98 minutes. It is approximately 120 minutes.
We will convert from minutes to hour.
60 minutes = 1 hour
120 minutes = 120/60 = 2 hours
Answer:
18ft^2
Step-by-step explanation:
to find area of a triangle you you multiply the base times height then divide by 2 which for this question will come out to be 2. The area of square in this question is 4 time 4 which equals to 16. 16 plus 2 is 18, so the and is 18ft^2
