Answer:

Volume = 120 cubic cm

Step-by-step explanation:

We would apply the formula for determining the volume of a square bases pyramid which is expressed as

Volume = 1/3 x base area x height

From the diagram,

length of square base = 6 cm

The base area = 6^2 = 36

height = 10

Thus,

Volume = 1/3 x 3/6 x 10

Volume = 120 cubic cm

I hope this help you! :)

Beth rented a bike from Julia's Bikes. It cost $19.60 plus $6 per hour. Write an expression for the total cost Beth had to pay

valentinak56 [21]

Answer:

c = 6t + 19.60

Step-by-step explanation:

Let t = the time in hours for which Beth rented the bike. Then

6t = the rental cost for the bike and

$19.60 = the up-front cost

The expression for the total cost (c) is

c = 6t + 19.60

Rolling Dice Roll two standard dice and add the numbers. What is the probability of getting a number larger than 9 for the first

Rudik [331]

Answer:

$\frac{1}{6}$

Step-by-step explanation:

The sum is larger than 9, it means we have: 10, 11, and 12

To get the outcome is 12, we have only one way is that the two dice shows face-6. The probability to have 12 is:

P(12) = $\frac{1}{6} *\frac{1}{6}$ = $\frac{1}{36}$

To get 11, we have it two ways once dice shows face-5 and the other shows face-6 and vice versa

P(11) = 2* $\frac{1}{6} *\frac{1}{6}$ = $\frac{1}{18}$

To get 10, we have it three ways ( once dice shows face-5 and the other shows face-6 and vice versa , two dice show 5)

P(10) = 3* $\frac{1}{6} *\frac{1}{6}$ = $\frac{1}{12}$

So the probability of getting a number larger than 9 for the first time on the third roll is:

P(12) + P(11) +P(10 )

= $\frac{1}{36}$ + $\frac{1}{18}$ + $\frac{1}{12}$ = $\frac{1}{6}$
