Answer:

Step-by-step explanation:

2/150 can be simplified to 1/75

this means that for every 75 products, 1 will be a defect.

divide 3000 by 75 and you will have your answer.

3000/75 =40.

it is likely there will be 40 defects

another method for this:

1/75 = ?/3000

75 x 40 = 3000 (this means that the denominators are equal. now we must multiply the top number by the same thing)

1x40 = 40.

telo118 [61]

Simple, change 25% into 0.25.

Thus,

n=0.25*200
n=50

thus, your answer is, 25% of 200 is 50.

Two cyclists leave city at same time, one going east and the other going west. The westbound cyclist bikes 3 mph faster than the

Bumek [7]

Speed of the east bound cyclist is 12 mph and the speed of west bound cyclist is 15 mph.

<u>Solution:</u>

Let us assume that x is speed of slower eastbound cyclist

So, x+3 will be the speed of faster westbound cyclist

We know that distance is the product of speed and time. That is,

$\text{Distance}=\text{Speed}\times\text{Time}$

West-bound DATA:

Rate of speed = x+3 mph ; Time = 6 hrs ; distance = 6(x+3) = 6x+18 miles

East-bound DATA:

Rate of speed = x mph ; time = 6 hrs. ; distance = 6x miles

On solving,

Distance apart = 162

$\Rightarrow6x+18+6x = 162$

$\Rightarrow12x=162-18$

$\Rightarrow x=\frac{144}{12}\rightarrow x=12$

So, the rate of speed of the east bound cyclist is 12 mph and the rate of speed of the west bound cyclist will be $x+3=12+3=15 \text{ mph}$
