Jimmy spent 1 hour planting 15 trees. How long would it take to plant 18 such trees?

1.2 hours or 1 hour 12 minutes

Step-by-step explanation:

We can use ratios to solve

1 hour        x hours

=

15 trees      18 trees    

Using cross products

1*18 = 15x

Divide by 15

18/15 = x

1.2 hours

1.2 * 60 minutes = 72 minutes

1 hour 12 minutes

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
