You and three friends own a paint shop. the shop's profit was $536 in the first month. you always divide the profits equally. in two months, each of you had made $224. how much profit did the shop make in the second month?

Step 1

Find the profit in two months

Multiply the total amount made by the whole group in two months () by the total number of persons ()

Step 2

Find the profit of the shop in the second month

we know that

so

substitute the values

therefore

the answer is

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

yes. we do proportions in probabilities.
