Wendy simulates the situation by creating a deck of 20 cards, each labeled with a different number from 1 to 20. She picks a card, then returns it to the deck, 4 times. Each time a number greater than 8 appears, it represents a snowy day.

This table shows the results of 100 trials:

Josh went to the store and bought chicken that was on sale, he could buy 8 pounds for $15.92 or 5 pounds for $9.95.

Answers

Answer: They are both 1.99 a pound.

Step-by-step explanation:

So we need to find the price per pound to compare the two choices. You take the price then divide it by the number of pounds. 15.92/8=1.99. So $1.99 a pound and then the same for 9.95/5 which is also equal to 1.99. Both come out to be 1.99 per pound so there is no better buy. Cost would be same.

Answer:

Answers

Answer:

W=Whole (Your original number)

A=0.8x71

A=56.8

All of the following are equivalent to 2(2a + b) + 8, except _____.
A. 4 a + 2 b + 8
B. 4( a + b + 2)
C. 4 a + 2( b + 4)

Answers

Answer:

B. 4( a + b + 2)

Step-by-step explanation:

Task: Simplify 2(2a + b) + 8

1. Distribute the 2

4a + 2b + 8

---------------------

Evidently, that is the same as A, so A is correct.

Now if we try C, 4a + 2(b+4), we see we need to simplify to check.

So let us distibute the 2.

4a + 2b + 8. Also correct.

This probably means that B is incorrect.

4(a + b + 2)

Let's distribute the 4.

4a + 4b + 8

This is incorrect because only have two "b".

Answer:

1) 16

2) 20

3) -12

4) 16

Step-by-step explanation:

1) Substitute the r for 4 like it tells you in the question so 12 + 4 = 16.

2) Substitute d with -3 so 5(-3+7) = 5 x (4) = 20

3) Substitute m for 4 so -48 / 4 = -12

4) Angle of triangle is half base times height or 1/2 x b x h

And since the base is 4 and the height is 8:

1/2 x 4 x 8 = 1/2 x 32 = 16

Or in other words:

1/2 x 32 = 32 / 2 = 16

48 lol I think

120 x 80%

80% because 4/5 of his text are to friends

96/ one half

One half because half of his text are to her

Answer:

The answer is

→ 48 text messages

Step-by-step explanation:

Were being asked how many text messages are to Bianca. Today, were using 3 ways on how to solve this problem. 2 are incorrect and 1 is correct.

First, let's use addition.

[tex]120+\frac{4}{5} +\frac{1}{2} =121.3[/tex]

Were not looking for 121.3, it's too high. Therefore, using addition is incorrect.

Second, let's use subtraction..

[tex]120-\frac{4}{5} -\frac{1}{2} =118.7[/tex]

Were not looking for 118.7 either. Therefore, using subtraction is incorrect as well.

Third, let's use multiplication...

[tex]120 * \frac{4}{5} * \frac{1}{2} = 48[/tex]

As a result we got 48. Which is the answer your looking for.

Hope this helped! :^)

Length = 50 feet

Width = 160 feet

Explanation:

I'm assuming the flagpole is not included in this question.

The length compared to the width is:

110

<-- equation 1

The formula for perimeter:
