Determine the volume of the box and the block.

Determine the ratio of the block to the box:

The volume of box=(L)(W)(H)

The volume of the block (L)(W)(H)

Multiply this number by 100 to turn it into a percent.

Complete this statement: The volume of the block is _____ percent of the volume of the box.

Determine the ratio of the number of hits to the number of shots:

(number of hits100 shots)

Multiply this number by 100 to turn it into a percent.

Complete this statement: The block was hit _____ percent of the time.

Compare the results of step 2 to the results of step 3. Are the percentages similar?

Write a conclusion discussing the following items:

Based on your findings, do you think Rutherford's hypothesis was reasonable?

You have 200 items that cost $20 and you are selling them at the price of $100.
allochka39001 [22]

Your total profit is $13,000. First you bought the 200 items for $20 each. That costs $4,000. Then you sold $50 of the items at $100 each. That’s $5,000. So already you’re in the green. You’ve already made $1,000 profit. Then you sold the rest of the items at a 20% discount. 150 items multiplied by $80 is $12,000. $12,000 plus the $1,000 equals $13,000 total.

What is a 15 of the sequence -7, 2, 11, ...?<br><br> A. 128<br> B. 110<br> C. 136<br> D. 119
gregori [183]

Answer:

D. 119

Step-by-step explanation:

To find the common difference, we take the second term and subtract the first term

2-(-7) = 9

We check  by taking the third term and subtracting the second

11-2 = 9

The common difference is 9

The formula for an arithmetic sequence is

an = a1 +d(n-1)

where a1 is the first term, d is the common difference and n is the number of the term in the sequence

a1=-7, d=9 and we are looking for the 15th term  so n=15

a15 = -7 +9(15-1)

a15 = -7+9(14)

      =-7 +126

      = 119
