6. A sporting goods store receives an order of 100 baseball caps, of which 22 are green. If 1 of
Taya2010 [7]

Answer:

\text{A. }39/50

Step-by-step explanation:

The probability that a randomly selected cap will not be green is equal to the number of non-green caps divided by the total number of caps.

Since there are 100 caps total and 22 are green, there must be 100-22=78 non-green caps.

Divide this by the total number of caps (100) to get the probability that a randomly selected cap will not be green:

\frac{78}{100}

Simplify by dividing both the numerator and denominator by 2:

\frac{78}{100}=\boxed{39/50}

two passenger train traveling in opposite directions meet and pass each other. Each train is 1/18 miles long and is traveling at
xz_007 [3.2K]

9514 1404 393

Answer:

  5 seconds

Step-by-step explanation:

Suppose the front parts of the trains meet at point A. Since both are the same length and traveling the same speed, each will pass point A in time ...

  time = distance/speed

  time = (1/18 mi)/(40 mi/h) = (1/720 h) × (3600 s)/(1 h) = 5 s

That is, the rear part of each train will be at point A 5 seconds after the front part.

The rear parts will pass each other 5 seconds after the front parts meet.

A blueprint for a house has a scale of 1:5 feet. The living room has a length of 2.5 inches and a width of 3 inches. What is the
stiks02 [169]

Answer:

Step-by-step explanation:

Set this up as a proportion, with inches on the top and feet on the bottom for our scale.  We will find the actual length first, then we'll find the width.

\frac{in}{ft}:\frac{1}{5}=\frac{2.5}{x}

Cross multiply to get that the actual length is 5(2.5) = 12.5 feet.  Now for the width:

\frac{in}{ft}:\frac{1}{5}=\frac{3}{x}

Cross multiply to get that the actual width is 5(3) = 15 feet.

If you want the area of the room, multiply the length times the width to get

A = 15(12.5)

A = 187.5 feet squared
