Sally bought the pizza shown above for lunch, which was cut into 10 equal slices.What percentage of the pizza did sally eat if s
Rashid [163]

Answer:

DM

Step-by-step explanation:

We can represent the pizza as 1. And every time we take a slice, we take percentage away. This pizza is cut up equally into 10 slices. So, if we take away a slice, we take away 1/10 of the pizza. What if Sally ate 6 slices? Same difference. She took away 6/10 of the pizza.

And to answer the question, "What percentage of the pizza did Sally eat if she had six slices?"

We will convert the 6/10 into a percentage. First convert the fraction into a decimal then into a percent.

To convert a fraction into a decimal, simply divide it's numerator by it's denominator.

6/10 = 0.60

And to convert a decimal into a percentage, move the decimal point two places to the right and change it into a % sign.

0.60 = 60%

So, the answer to this question C) 60%

Solve for p.
KonstantinChe [14]

Hi,

Answer: All Real Numbers

This can be achieved in 7 easy steps!

<u>My Numerical work:</u>

1. 2p + 3 > 2(p - 3)

Simplify both sides of the inequality:

2. 2p + 3 > 2p - 6

Subtract 2p from both sides:

3. 20 +3 - 20> 2p - 6 - 2p

4. 3 > -6

Subtract 3 from both sides:

5. 3 -3 > -6 - 2p

6. 0 > -9

7. All real numbers are solutions.

I Hope I Helped!

Regina has a bag of marbles that contains 3 blue marbles, 4 red marbles, and 5 yellow marbles. She draws one marble, then replac
iVinArrow [24]

Answer:  

Possible outcomes=12

P(\text{Blue marble first})=\frac{1}{4}

P(\text{Yellow marble})=\frac{5}{12}

P(\text{ Blue then yellow})=\frac{5}{48}

Step-by-step explanation:

We can see these two events are independent as Regina replaced marble after drawing one marble.

We can find possible outcomes by adding number of blue, red and yellow marbles.

\text{Possible outcomes}=3+4+5=12

Let us find probability of getting a blue marble on first draw.

P(\text{Blue marble})=\frac{3}{(3+4+5)} =\frac{3}{12} =\frac{1}{4}

Now we will find probability of getting yellow marble.

P(\text{Yellow marble})=\frac{5}{(3+4+5)} =\frac{5}{12}

We can find probability of getting a blue marble and then yellow marble by multiplying both probabilities.

P(\text{ Blue then yellow})=\frac{1}{4}* \frac{5}{12} =\frac{5}{48}

Therefore, probability of getting a blue marble and then yellow marble is \frac{5}{48}.
