A combination lock has numbers 0-49 on it. How many different 3-digit lock
Harman [31]

Answer:

19,600

Step-by-step explanation:

0-49=50 numbers

n=50

r=3

C(n,r)=n!/(r!(n-r)!)

=50!/(47!)(3!)

C(n,r)=C(50,3)

=50!/(3!(50−3)!)

= 19600

A high school sports team is ordering sports drinks online from a company. The price of sports drinks varies, based on the numbe
Elena-2011 [213]

The amount of drinks is a linear function of the number of drinks. The maximum amount that can be purchased is 100 soft drinks.

Let

y \to amount of drinks

x \to number of drinks

For drinks not more than 50

y = 10 + 0.8x

For drinks more than 50.

y = 15 + 0.7x

For a purchase of $85, it means that:

y = 85

So, we solve for x in both equations.

y = 10 + 0.8x

85 = 10 + 0.8x

Collect like terms

0.8x = 85-10

0.8x = 75

Divide through by 0.8

x = 93.75

x = 94 --- approximated

y = 15 + 0.7x

85 =15 + 0.7x

Collect like terms

0.7x = 85 - 15

0.7x = 70

Divide by 0.7

x = 100

By comparing both values:

x = 100

x = 94

100 > 94

Hence, the maximum amount that can be purchased is 100
