For this case we have that the temperature drops steadily at a speed of 0.8 \frac {degrees} {hour}, that is, every hour drops 0.8 degrees. So, we can propose a rule of three:

1 hour ----------> 0.8 degrees

x ------------------> 4.4 degrees

Where the variable "x" represents the number of hours that must pass for the temperature to decrease by 4.4 degrees.

x = \frac {4.4 * 1} {0.8}\\x = 5.5

Thus, for the temperature to decrease by 4.4 degrees, 5.5 hours must pass.

Answer:

5.5 hours

Number 33 in which store can you buy 30 oranges with the least amount of money ?
BartSMP [9]

You simply need to find the price of one orange at each store, and multiply that by 30.

Store A: 5/3= around $1.67= 1.67*30= $50.10

Store B: 3/2= $1.50= 1.5*30= $45.00

Store C: 9/5= $1.80= 1.8*30= $54.00

Store D: $1.25= 1.25*30= $37.50

As you can see above, at Store D, 30 oranges would only cost $37.50, making it the cheapest store to buy oranges.

I hope this helps :)

during a baseball game, a player's ball hit into the outfield is modeled by the equation h=-16t^2 + 65t. A bird flying across th
Hatshy [7]
The intersections of the equations represent the times when the bird and the ball are at the same height.

8t+20=-16t^2+65t

16t^2-57t+20=0, using the quadratic equation for expediency:

t=(57±√4529)/32 and since we know t>0

t≈3.88 seconds  (at a approximate height of 51 feet)

66 oz = __lb in a mixed number
aivan3 [116]

Answer:

4\frac{1}{8} pounds

Step-by-step explanation:

1 pound = 16 ounces

\frac{66}{16} =\frac{y}{1}

16 × y = 66 × 1

16y = 66

16y ÷ 16 = 66 ÷ 16

y=4\frac{1}{8}

The best fit curve for #1 is D. The easiest way to check these is by pluggin in to the equation and seeing if they come close. By doing just the first ordered pair along, it is apparent that only D will work.

With x = 1 input

A) -36

B) 24.2

C) 17.5

D) 11.58

#2 is also D. We can tell this because multiplying any of these options always results in a middle term between them. For instance, if you multiply out C, you will not only get x^4 and x^4, but you will also get terms such as 4x^2y^2 in the middle.
