Two groups of staff at a store are making flowers to decorate the entrance. if group a were to do it alone, it would take them 10 hours to complete the task. if group b were to do it alone it would take them 15 hours. the groups decided to work together. group b took a break for 1 hour and 40 minutes. group a ended up making 300 more flowers than group b. how many flowers are there altogether?

Step-by-step explanation:

Let x be the number of flowers. If Group A were to make x flowers alone, it would take them 10 hours to complete the task, then they make flowers in an hour.  If Group B were to make x flowers alone, it would take them 15 hours to complete the task, then they make flowers in an hour.

The groups decided to work together. They can make together in an hour and it takes them hours. Group B took a break for 1 hour and 40 minutes ( hour), then Group B works

hours.

Thus,

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
