Answer:
Step-by-step explanation:
<u>Given</u>
<u>Solve for h</u>
- S = 2πr² + 2πrh
- 2πrh = S - 2πr²
- h = (S- 2πr²)/(2πr)
Ok...so u have 4 people sharing this plan...they each pay for their own data..however, the $ 90 flat rate is split between them equally.
90/4 = 22.5....so each of them pay 22.50 each for the flat rate.
so John's equation is : 22.5 + 0.25x = 147.50
Answer:
The dilation is an enlargement
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal and this ratio is called the scale factor
In this problem Triangles A'B'C' and ABC are similar by AA Similarity Postulate
Let
z------> the scale factor
so
substitute the values
The scale factor is greater than 1
therefore
The dilation is an enlargement

Step-by-step explanation:
Answer:
D. 8 bottles
Step-by-step explanation:
one bottle of one is obviously $6.50
one bottle of two : $12.50 (1/2) = $6.25
one bottle of four: $26.00 (1/4) = $6.50
one bottle of six: $30.00 (1/6) = $5.00
one bottle of eight: $38.00 (1/8) = $4.75
8 bottles is the best buy
