Andre is planting saplings (baby trees). It takes him 30 minutes to plant 3 saplings. If each sapling takes the same amount of time to plant, how long will it take Andre to plant 14 saplings? If you get stuck, consider using the table.

Answers

Answer:

140 minutes

Step-by-step explanation:

If it takes him 30 mins to plant three, then 30 divided into three equal groups is 10. Then we multiply 14 and 10 together since it takes Andre ten minutes to plant each sapling. This means  that the 14 saplings takes ten minutes EACH to plant.

Step-by-step explanation:

bc

Answer:

(2/5)√5

Step-by-step explanation:

from the sine rule (see attached for reference), we can construct the following relationship

12/sinθ  = (6√5) / sin 90°

recall that sin 90° = 1, hence our equation becomes:

12/sinθ  = (6√5) / 1

12/sinθ  = (6√5)   (rearranging)

12 ÷ (6√5)  = sin θ

sin θ = 12 / (6√5)

sin θ = 2 / √5   (moving radical to numerator by multiplying by √5/√5)

= 2 / √5     x     √5/√5

= 2√5 / 5

= (2/5)√5

Step-by-step explanation: the four is on the side and 2 is over 3

Answer:

4 and 2/3

Step-by-step explanation:

3/3= 1 whole

14/3 - 3/3 =11/3 - 3/3= 8/3 - 3/3= 5/3 - 3/3= 2/3

No more 3/3, or 1 whole, can be subtracted, so you add the number of 3/3, or 1 whole, that you subtracted, which adds up to 4 wholes, and then you add the 2/3, which would equal 4 and 2/3.

melanie walks 2 large dogs and 8 small dos as part of her dog walking business the simplified ratio of large dogs to small dogs is

Answers

Answer:8:36

Step-by-step explanation:

Answer: 1 : 4

Step-by-step explanation:

The simplified ratio of large dogs to small dogs is 1 : 4.

The original, unsimplified ratio would be 2 : 8, because there are 2 large dogs for every 8 small dogs. But to simplify it, we can divide each side by 2.

2 ÷ 2 = 1, while 8 ÷ 2 = 4.

Therefore, the simplified ratio of large dogs to small dogs is 1 : 4.
