Answer:

<u>Proportion:</u>

<u>4/15 = 20/75</u>

<u>Sam will bike 37.5 km after 10 days.</u>

Step-by-step explanation:

1. Let's review the information given to answer the question correctly.

Number of days Sam has gone to work biking = 4

Amount of kilometers Sam has logged on his bike = 15

2. a. Set up a proportion to solve the amount of km he will log after 10 days on the bike.

Number of days Sam has gone to work biking = 4

Amount of kilometers Sam has logged on his bike = 15

2. a. Set up a proportion to solve the amount of km he will log after 10 days on the bike.

4/15 = 20/75

b. Solve for the amount of km in part (a).

Let's use the proportion, this way:

20/75 = 10/x

20x = 75 * 10

20x = 750

x = 750/20

x = 37.5

<u>Sam will bike 37.5 km after 10 days.</u>

A 10-inch sunflower is planted in a garden and the height of the sunflower increases exponentially. The height of the sunflower
Misha Larkins [42]

Answer:

5-day growth factor is 27.027-inch

Step-by-step explanation:

Given;

the initial height of the sunflower = 10-inch

the rate at which the height increases = 22%

time of growth = 5 days

To calculate 5-days growth factor, we apply the formula below, since it grows exponentially;

=10-inch [1+\frac{22}{100}] ^5\\\\= 10-inch(2.7027)\\\\= 27.027-inch

Therefore, 5 day growth factor is 27.027-inch

Mr. Selan loves the 99-cent menu at Wendy's (sadly prices went up a few years ago). He used to buy two chicken sandwich at 99-ce
iogann1982 [59]

Answer:

Mr. Selan would pay $2.15 for the sandwiches with tax.

Step-by-step explanation:

Given that:

Cost of each sandwich = 99 cents

Cost of two sandwiches = 99*2 = 198 cents

Sales tax = 8.5%

Sales tax = \frac{8.5}{100}*198=16.8\ cents

Sales tax = 17 cents

Total cost = 198 + 17 = 215 cents

Total cost = $2.15

Hence,

Mr. Selan would pay $2.15 for the sandwiches with tax.

Peggy had three times as many quarters as nickels. She had $1.60 in all. How many nickels and how many quarters did she have?
saul85 [17]

Answer:

<em>3n; 2 nickels and 6 quarters</em>

Step-by-step explanation:

"Peggy had three times as many quarters as nickels."

Whatever number of nickels she has, the number of quarters is 3 times as many.

Since she has n nickels, she has 3 times n quarters.

The number of quarters is 3n.

A nickel is worth $0.05, so n nickels are worth 0.05n.

A quarter is worth $0.25, so 3n quarters are worth 0.25(3n).

0.05n + 0.25(3n) = 1.60

0.05n + 0.75n = 1.6

0.8n = 1.6

n = 2

She has 2 nickels.

3n = 3(2) = 6

She has 6 quarters.
