The crew of apollo 17 consisted of 2 pilots and a geologist. Suppose that nasa had actually trained 9 pilots and 4 geologists as

Troyanec [42]

They could have assembled total 336 different possible crews.

<em><u>Explanation</u></em>

Total number of trained pilots is 9 and geologists is 4.

The crew should be consisted of 2 pilots and 1 geologist. That means, <u>2 pilots are chosen from total 9 and 1 geologist is chosen from total 4</u>.

Number of ways for choosing 2 pilots from 9 $= ^9C_{3} =84$ and

Number of ways for choosing 1 geologist from 4 $=^4C_{1}= 4$

So, the total possible number of different crews they could have assembled $=84*4= 336$

A barrier in the shape of a rectangle is used to retain oil spills. On a blueprint, a similar barrier is 9 inches long and 2 inc

drek231 [11]

Width of the actual barrier = 1.2 miles

Width of the barrier in the blueprint = 2 inches

2 inch dimension of blueprint = 1.2 miles of original

So, 1 inch dimension of blueprint = 1.2/2 = 0.6 miles.

Since the length of the barrier in the blueprint = 9 inches,

length of the actual barrier = 9(0.6) = 5.4 miles.

The price of a recipe-book was reduced from $24.50 to$17.95. If p represents the percent decrease in price of the book, which pr

LuckyWell [14K]

Answer:

The required proportion is $\frac{p}{100}=\frac{24.50-17.95}{24.50}$ .

Step-by-step explanation:

Consider the provided information.

The price of a recipe-book was reduced from $24.50 to$17.95.

The original price is 24.50

Reduced price is 17.95.

Let p represents the percent decrease in price of the book.

$\text{Percent decrease}=\frac{\text{Original price-Reduced price}}{\text{Original price}}\times 100$

Now substitute the respective values in the above formula.

$p=\frac{24.50-17.95}{24.50}\times 100$

$\frac{p}{100}=\frac{24.50-17.95}{24.50}$

Hence, the required proportion is $\frac{p}{100}=\frac{24.50-17.95}{24.50}$ .
