The is a 50% chance of being a boy or a girl.....previous siblings do not matter. Every child is an independent event. So even if u had 2 siblings that were boys, the result of the next one being a boy is still gonna be 50%...just as the odds of it being a girl, is 50% as well.

500 − 250 = 250 pieces left after donation

Yolanda got 180 pieces....then Enrique got 70 pieces

So he got 70 /250 = 7/25 = 28% of the remaining candy

Jerry is mowing his lawn .it takes him 1/6 of an hour to mow 3/20 of his years .what portion of the yard does jerry now per hour

Ber [7]

Given that Jerry mows 3/20 yards of lawn in 1/6 hour.

Now we have to found how much Jerry can mow per hour.

We know that "work" and "time" are in direct proportion so we can setup the ratio of work and time to easily find the required work.

$\frac{Portion \; \; of \; \; lawn \; \; mowed}{time}=\frac{\frac{3}{20}}{\frac{1}{6}}$

$\frac{Portion \; \; of \; \; lawn \; \; mowed}{1}=\frac{\frac{3}{20}}{\frac{1}{6}}$

$Portion \; \; of \; \; lawn \; \; mowed=\frac{3}{20}*\frac{6}{1}$

$Portion \; \; of \; \; lawn \; \; mowed=\frac{18}{20}$

$Portion \; \; of \; \; lawn \; \; mowed=\frac{9}{10}$

Hence final answer is $\frac{9}{10}$ yards.

Brian drives 215 miles at an average speed. He then travels 75 more miles at a speed

Sedaia [141]

His average speed for the first trip is 43 mph

Since Brian's average speed is x and he travels the first part for 215 miles in time t.

So, his distance d = xt

Also, the travels 75 more miles at a speed of 15 mph.

Since distance = speed time, the time he takes to cover this distance is

t' = distance/speed = 75 mi/15 mph = 5 hours

Since he covers both distances in the same time, we have that t = t' = 5 hours.

So, his average speed for the first trip x = d/t

= 215 mi/5 h

= 43 mph

His average speed for the first trip is 43 mph
