Answer:

Rate for 100 miles = $ 6 / miles

Rate for 250 miles = $ 3.3 / miles

Step-by-step explanation:

Given that cost for covering 100 miles by flight is $600.

As rate is the cost of covering unit distance (in miles).

So, the rate to cover 100 miles by flight = $ 600/ 100 miles = $ 6 /miles.

Similarly, the cost of covering 250 miles by flight is $825.

So, the rate to cover 250 miles by flight = $ 825/ 250 miles = $ 3.3 /miles.

Is xy = yx? Explain how you know
blagie [28]

Answer:

Yes

Step-by-step explanation:

xy=yx because either way, you would end with the same product. For example, if x was 3 and y was 2, you would have (3)(2)=(2)(3), giving you 6=6 which is, in fact, a true statement.

How much fabric is required to cover x buttons in the shape of a circle whose radius is 3x ?
Leviafan [203]

Radius of 1 button = r = 3x

Fabric required to cover 1 button = Area of the circle

= \pi r^{2}

= \pi (3x)^{2}

= 9\pi x^{2}

Total number of buttons = x

Fabric required to cover 1 button = 9\pi x^{2}  

Fabric required to cover x buttons = x(9\pi x^{2} )

=9\pi x^{3}

Hence, fabric required to cover x buttons =9\pi x^{3}  sq. units

Step-by-step explanation:

Of 24 employees at a local supermarket, 13 work as cashiers  and 11 stock shelves. If 4 employees are selected at random to work overtime, then

P( all 4 are cashiers) = \frac{^{13}{C}_{4}}{^{24}{C}_{4}}

                                 \simeq 0.06729

Suppose that an individual has a body fat percentage of 19.3% and weighs 187 pounds. How many pounds of her weight is made up of
Hatshy [7]

Answer:

The individual has 36.09 pounds of body fat.

Step-by-step explanation:

Given that an individual has a body fat percentage of 19.3% and weighs 187 pounds, to determine how many pounds of her weight is made up of fat the following calculation must be performed:

(187 x 19.3) / 100 = X

3.609.1 / 100 = X

36.091 = X

Therefore, the individual has 36.09 pounds of body fat.
