Step-by-step explanation:

Loss of water per minute = 2.5 gallons

Loss of water for 7 minutes = 2.5 * 7 = 17.5 gallons

Franco is at the state fair with some friends. He is deciding between buying a jumbo pack of 50 ride tickets for $45 or a medium

jasenka [17]

Answer:

The jumbo pack is a better deal

Step-by-step explanation:

The better deal of two is the one that offers a lower cost per ride. Considering the two deals, the cost per unit ride for;

a jumbo pack of 50 ride tickets for $45 = $45/50

= $0.90 per ride

a medium pack of 30 ride tickets for $28.50

= $28.50/30

= $0.95

From the computations above, the medium pack (at $0.95) is more costly than the jumbo pack (at $0.90). Hence the jumbo pack is a better deal for Franco.

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point (-1, -3.75)

Point (-1, 4.5)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-1--1)^2+(4.5--3.75)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(0)^2+(8.25)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{0+68.0625}$
[√Radical] Add: $\displaystyle d = \sqrt{68.0625}$
[√Radical] Evaluate: $\displaystyle d = 8.25$
