A baker records the internal temperature of a pie that has been left out on the counter. The room temperature is 14 Celsius. An

equation that models this situation is T (t) =68 (0.5)^r/10 where T is the temperature in degrees Celsius and t is the time in minutes. Determine the temperature to the nearest degree,of the pie after 15
minutes. How much time did it take for the pie to reach an internal temperature of 31°C?

Assume r= t  not sure if you mistyped this.
t =  15 min

T(t)  = 68 (0.5)^(15/10) = 24 Celsius

31 = (0.5)^(t/10) take ln

ln31 = (t/10) ln (0.5) + ln68

t = (ln32 - ln 68/ln0.5) * 10 = 11.3 min

Find all polar coordinates of point P = (6, 31°).
wel

as far as I can tell, is just a matter of going around the circle many or infinite times around.

so 6,31° is the first point, the next point will be one-go-around, 6, 31+360 => 6, 391°

then the next will be 6, 391+360 => 6, 751° and so on.

so we can say is (6, 31° ±360°n), n ∈ ℤ.

Suppose that in a survey of 1,000 U.S. residents, 721 residents believed that the amount of violent television programming had i
Art [367]

Answer: 0.813

Step-by-step explanation:

Let A be the event describes the number of residents believed that the amount of violent television programming had increased over the past 10 years.

& B be the event describes the number of residents believed that the amount of violent television programming had decreased over the past 10 years.

Given : n(A)=721   ;  n(B)=454  ;  n(A∩B)=362

We know that ,

n(A\cup B)=n(A)+n(B)-n(A\cap B)

i.e. n(A\cup B)=721+454-362=813

Also, the total number of U.S. residents surveyed n(S)= 1,000

Then, the  proportion of the 1,000 U.S. residents believed that either the amount of violent programming had increased or the overall quality of programming had decreased over the past 10 years will be :-

P(A\cup B)=\dfrac{n(A\cup B)}{n(S)}=\dfrac{813}{1000}=0.813

Hence, the required answer = 0.813

If 300 boxes of medical sponges cost $25.00, how many boxes can you purchase for $0.50?
nikdorinn [45]
You can purchase 6 boxes of medical sponges for $0.50.

Step 1:
Divide 300 by 25.00
300/25= 12
So you get 12 boxes for 1 dollar.
We have 50 cents.

Step 2:
Multiply 12 by 0.50
12*.5 = 6
So you can buy 6 boxes for $0.50.

Hope this helps you! (:

Town Hall is located 4.3 miles directly east of the middle school. The fire station is located 1.7 miles directly north of Town
Maksim231197 [3]

Answer:

2.1 miles

Step-by-step explanation:

you can see a drawing of the situation in the attached picture (you need to draw all the places mentioned and the distance between them),

this way we can form a right triangle  between the school and the hospital with measures of sides: 1.7 and 1.2 miles

and the green line is the straight line between the school and the hospital, so you need pythagoras to find the value:

\sqrt{1.7^2+1.2^2}\\=\sqrt{2.89+1.44}\\=\sqrt{4.33}  \\ =2.081

rounding to the nearest tenth:

2.1 miles
