Answer:

The total amount of money Alex spends on 5 DVD = $ 35.

Step-by-step explanation:

Total number of DVD purchased by Alex = 5

The cost of each DVD = $9

So, the total cost of purchasing 5 DVD = 5 x ( csot of 1 DVD)

= 5 x ( $ 9) = $ 45

Now , the discount if 1 DVD = $ 2

So, the total discount of 5 DVD = 5 x ( Discount on1 DVD)

= 5 x ($ 2) = $ 10

⇒ The total amount Alex spends

= Total cost of 5 DVD - Discount on 5 DVD

= $ 45 - $ 10 = $ 35

Hence, the total amount of money Alex spends on 5 DVD = $ 35.

52 regular playing cards are randomly dealt to four players with each players receiving 13 cards. What is the probability that e
Vadim26 [7]

Answer:

The probability is 1/28,561

Step-by-step explanation:

Here, we want to find the probability that each of the players will receive exactly one ace.

In a deck of cards, we have 4 suites of 13 cards each, with each of the suites consisting of 1 ace.

So, the probability of getting an ace for each of the four players will be 4/52 = 1/13

Now, the probability of each of the players getting exactly one ace will be; first got one ace , second got one , third got one and fourth got one.

mathematically, this probability will be 1/13 * 1/13 * 1/13 * 1/13 = (1/13)^4 = 1/28,561

Describe a real life multiplication situation for which an estimate makes sense
Drupady [299]
If you are trying to create a garden of potted plants, you would find out how much soil each pot needs/holds and multiply that by how many pots you plan to use. then you would go to the store for potting soil, which let’s say came in smaller packs and you need to purchase multiple. use multiplication estimation to estimate how many bags you’d need.
I know this is a dumb example...sorry this is one I remember from my fourth grade math teacher ahah

Lapatulllka [165]

Answer:your question seems incomplete but if you looking to find the resulting equation to solve for temperature at a particular time you can use this 28t^2

Step-by-step explanation:

F'(t) = 7(0.8)t

Integrating the RHS

Temp= integral of f'(t)= 28t^2

Therefore, T(°c)= 28t^2
