Answer:
Graph A.
Step-by-step explanation:
When Johnny starts moving <em>more </em>lawns, this means, in fewer weeks, he will have more total lawns mowed. We can see on the first graph, the blue line shows an increase of lawns mowed with fewer weeks.
Answer:
32
Step-by-step explanation:
We can’t find the area of the shape just like that. So we have to draw a line and cut the shape, which makes it 1 square and 2 of the same triangles.
Let’s solve for the square first.
Area=Length x Width
A=3 x 6
A=18in
Now the 2 triangles
Area=Base x Height/2
Area=1.5 x 3/2
Area=2.25in
Now add all of them together:
18+2.25+2.25=22.5in
If you had absolutely no idea, then you'd have roughly two choices
of how to find it:
#1). Try numbers until you find the right one.
Pick a number.
Cube it.
If you get less than 729, go back and try a bigger number.
If you get more than 729, go back and try a smaller number.
Eventually you find the right one.
Try 1. 1³ = 1 . Too small.
Try 2. 2³ = 8 . Still too small.
Try 5. 5³ = 125 . Still too small.
Try 20. 20³ = 8,000. Ooops. Too big.
Try 10. 10³ = 1,000 Too big.
Try 8. 8³ = 512. Oooo. Too small, but maybe getting close.
Try 8.5. 8.5³ = 614.125 Still too small, but very close.
Try 9. 9³ = 729 . That's it ! yay !
#2). x³ = 729
Take the log of each side: log(x³) = log(729)
3 log(x) = log(729)
Divide each side by 3 : log (x) = (1/3) log(729)
Look up log(729) : log(x) = (1/3) (2.86272...)
= 0.95424...
Raise 10 to the power
of each side: 10^log(x) = 10⁰·⁹⁵⁴²⁴···
x = 8.99994...
(That's the way it is with logs.
They never come out even.)
