IgorC [24]

Answer:

Matha - Jim = 200 feet.

Step-by-step explanation:

Jim's distance

J = sqrt(w^2 + L^2)

w = 300
L = 400

J = sqrt(300^2 + 400^2)

J = sqrt(900 + 1600)

J = sqrt(2500)

J = 500

Martha's distance

M = 300 + 400

M = 700 Feet

Answer

M - J = 700 - 500 = 200

Jim walks 200 feet less than Martha.

Mademuasel [1]

Given:

Laura has 160 pounds of green beans at her vegetable stand.

She sells 10 pounds of green beans every hour.

To find:

The percent decrease in green beans after 3 hours.

Solution:

We have,

Beans sold in 1 hour = 10 pounds

So, Beans sold in 3 hours = 30 pounds

Decrease in green beans after 3 hours is 30 pounds.

Now,

$\%\text{Decrease}=\dfrac{\text{Decrease in green beans after 3 hours }}{\text{Initial amount of green beans}}\times 100$

$\%\text{Decrease in green beans after 3 hours}=\dfrac{30}{160}\times 100$

$\%\text{Decrease in green beans after 3 hours}=\dfrac{300}{16}$

$\%\text{Decrease in green beans after 3 hours}=18.75\%$

Therefore, the correct option is A.
