Dolphin= 0.433 Lion=56.3% Rabbit= 19/40 Squirrel= Tiger=65.8%

Answers

The way to line the animals is to put them in order going down. 0.433 56.3% 19/40 65.8%. Then you try to figure out what you need to convert so that you can get your answer. 56.3% changes to 0.563 because you move the decimal two places to the left. 65.8% changes to 0.658 and 19/40 is 0.475. 0.433 0.563 0.475 0.658. Now you compare each row to figure them out. When you do that your answer will be 0.433, 0.475, 0.563, and 0.658. I sleep about 9/24 of the day which is 0.375 and I will fit right befor 0.433.

Ben has a cell phone plan that provides 200 free minutes each month for aflat rate of $39. For any minutes over 200, Ben is charged $0.35 per minute.
Which of the following piecewise functions accurately represents charges
based on Ben's cell phone plan?
A. f (x) =
39, x> 200
39+. 35, x < 200
B. f (x) =
39, x 200
35(x-200), x > 200
C. f(x) =
39,
x200
35x, x > 200
D. f (x) =
39.x200
39+. 35(x-200), x > 2001

Answers

Answer:

The piecewise functions accurately represents charges  based on Ben's cell phone plan is :

f(x)= 39, x \leq 200\nf(x)=39 + 0.35(x - 200), x > 200}

Step-by-step explanation:

Let x be the minutes over cell phone

Let f(x) represents the piecewise function that represents the charges based on Ben's cell phone plan.

We are given that Ben has a cell phone plan that provides 200 free minutes each month for a  flat rate of $39.

So,f(x)= 39, x \leq 200

We are also given that  For any minutes over 200, Ben is charged $0.35 per minute.

So, Minutes over 200 = x-200

f(x)=39 + 0.35(x - 200), x > 200}

Hence the piecewise functions accurately represents charges  based on Ben's cell phone plan is :

f(x)= 39, x \leq 200\nf(x)=39 + 0.35(x - 200), x > 200}

Bryan has a summer job of unloading fruit crates. Last week he unloaded 243 crates. This week he unloaded 361. How many more did Bryan unload this week than last week?

Answers

Answer:

The answer is 118

Step-by-step explanation:

In order to solve this you need to subtract this weeks, to last weeks.

361 - 243 = 118.

Hope this helps :)

Final answer:

Bryan unloaded 118 more crates this week than last week.

Explanation:

To find out how many more crates Bryan unloaded this week than last week, we can subtract the number of crates unloaded last week from the number of crates unloaded this week.

So, to find the difference, we subtract 243 from 361:

= 361 - 243

= 118

Therefore, Bryan unloaded 118 more crates this week than last week.

A six-sided number cube with faces numbered 1, 2, 3, 4, 5, and 6 is rolled. Which events are mutually exclusive? A. rolling a 4, rolling a prime number

B. rolling a 3, rolling a prime number

C.rolling a 2, rolling an even number

D. rolling a 5, rolling an odd number

Answers

The answer is A.

Mutually exclusive means something that can't happen at the same time.

You can't roll a 4 and say you got a prime number. So A is your answer.

B is wrong because if you roll a 3, you are also rolling a prime number.

C is wrong because if you roll a 2, you are also rolling an even number.

D is wrong because if you roll a 5, you are also rolling an odd number.
Hey there I see you need help well I  am here to do just that the answer is

A. because mutually exclusive events are not possible so you cant roll a 4 and have it be a prime number 

hope this helps
