Darryl and DeShawn each improved their yards by planting rose bushes and ornamental grass. They bought their supplies from the same store. Darryl spent $143 on 11 rose bushes and 3 bunches of
ornamental grass. DeShawn spent $132 on 11 rose bushes and 2 bunches of ornamental grass. What
is the cost of one rose bush and the cost of one bunch of ornamental grass?
A) rose bush: $14, bunch of ornamental grass: $18
3) rose bush: $13, bunch of ornamental grass: $16
- rose bush: $10, bunch of ornamental grass: $11
) rose bush: $15, bunch of ornamental grass: $10

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

at least two

step-by-step explanation:

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
