Answer:

about 1.4 hours

Step-by-step explanation:

3.13 gallons per minute.

60 minutes in an hour, so multiply both numbers by 60.

187.8 gallons per hour.

Divide the number of gallons we need to fill the tub the number of gallons put in per hour.

255÷187.8=1.375...

Round it, you get 1.4 hours.

It takes about 1.4 hours to fill the hot tub.

Points P, Q, and R are shown on the number line. What is the distance between point P and point Q? P(-76) Q(-24) R(0) A) 52 unit

Amiraneli [1.4K]

Answer:

A) 52 units

Step-by-step explanation:

The length of a line joining 2 points on a number line is given by the difference between the co-ordinates of the 2 points.

Therefore PQ= $\left ( Q \right )-\left ( P \right )= \left ( -24 \right )-\left ( -76 \right )= 52$

Hence the length of the line is 52 units

2. For the following, is the stated conclusion reasonable? Why or why not?

lapo4ka [179]

Answer:

Definetely, it is reasonable. You may assume that a pet as a companionship will help the elderly feel more comfortable and therefore, happy. There are a few problems tough:

There is no practical way of meassuring 'happiness'.
Sometimes, the correlations of two factors may be a coincidence. Scientist should always consider this when they try to claim something byusing some backup logic, like we did.
Even tough the statement makes some sense, you need to be aware that maybe is not completly positively correlated. Maybe having 20 more pets does not make an elderly happy if it alredy had 1 or 2.

31/4 + (12 - 3 6/11)

31/4 + (12 - 39/11)

31/4 + 93/11

= 713/44 = 16 9/44

At HD Sport & Fitness gym, analysis shows that, as the demand of the gym, the number of members is 83 when annual membership

gayaneshka [121]

The price at which revenue is maximized is $ 157, and maximum annual revenue is $ 6751.

Since at HD Sport & Fitness gym, analysis shows that, as the demand of the gym, the number of members is 83 when annual membership fee is $ 17 per member and the number of members is 81 when annual membership fee is $ 24 per member, and the number of members and membership fee have a linear relationship, to determine at what membership price is the maximized revenue, and what is the maximum annual revenue, the following calculations must be performed:

17 x 83 = 1411
24 x 81 = 1944
31 x 79 = 2449
38 x 77 = 2926
66 x 69 = 4554
73 x 67 = 4891
80 x 65 = 5200
94 x 61 = 5734
101 x 59 = 5959
122 x 53 = 6466
129 x 51 = 6579
150 x 45 = 6750
157 x 43 = 6751
164 x 41 = 6724

Therefore, the price at which revenue is maximized is $ 157, and maximum annual revenue is $ 6751.
