rodikova [14]

$10.71

Explanation

Step 1

you can easily solve this by using a rule of three.

Let

x represents the money Eileen will pay if her bag weighs 63 pounds

the proportion is the same

then

\frac{7.14}{42}=\frac{x}{63}

Step 2

solve for x

\begin{gathered} \frac{7.14}{42}=\frac{x}{63} \\ 63\cdot7.14=42x \\ x=\frac{63\cdot7.14}{42} \\ x=\frac{449.82}{42} \\ x=10.71 \\  \end{gathered}

I hope this helps you

A 5-digit combination lock with digits 0-9 can be opened only if a correct combination of digits is chosen. Find the probability
sammy [17]

The total number of combinations without restrictions is

10 * 10 * 10 * 10 * 10 = 100000

Problem A

10 * 9 * 8 * 7 * 6  = 30240

the number of ways the combination can be set up with no repetition.

The probability of such an event is P = 30240 / 100000 = 0.3024

Problem B

The number of ways that can be done with repetition and no zeros is

9 * 9 * 9 * 9 * 9 = 59049

The probability of such an event is

P = 59049 / 100000 = 0.59049

mart [117]

Answer:

No

Explanation:

Cube A surface area is : 2x2x6 (because there are 6 faces) = 24

Cube B surface area is 4x4x6 = 96

The surface area of the cube B isn't the twice of cube A's surface area

Now the volumes :

Cube A volume is 2x2x2 = 8

Cube B volume is 4x4x4= 64

Cube B's volume isn't the twice of cube A's volume
