The answer is 185 ft 2.

Since it is a parralellogram you have to multiply the base x height.
And it has a 2 right next to it because you multiplied base x height

Hope it helps!~

What is the value of x? A. 142 B. 152 C. 76 D. 71

Nadusha1986 [10]

Answer:

x has a value of 71, making D the correct answer.

Step-by-step explanation:

Because this is an isosceles triangle, we know that the bottom two angles are equal. We also know that the sum of the angles inside a triangle will always come to 180°. With that in mind, we can simply subtract 38° from 180° and divide by two to get the correct answer.

$x = (180 - 38) / 2\\= 142 / 2\\= 71$

So the correct answer is D, 71 degrees.

Answer: b.2x

Step-by-step explanation:

why? because 2 can be divided into all of the numbers evenly!

all the numbers have (x)

it wouldn't be (2x^2) ,because one of the numbers have x^3

92 because 8*12 is 96. Then, you have to do 96 - 4 which is 92.

Identify the use of charts, graphs, and data in everyday applications.

astra-53 [7]

Answer:

For this you need to see where you can find graphs, data, and charts in your life. You can create a chart for things you notice in recent weather, bird behaviors, etc. If I gave you an entire answer, it might not line up with where you are. Example: If I took notes and created a chart for how often it rained and said that it rained every other day throughout the week, it may not line up from where you are.

Step-by-step explanation:

I wish you the best of luck on your assignment!

A roast turkey is taken from an oven when its temperature has reached 185 degrees F and is placed on a table in a room where the

Vedmedyk [2.9K]

(a) Using Newton's Law of Cooling, $\dfrac{dT}{dt} = k(T - T_s)$ , we have $\dfrac{dT}{dt} = k(T - 75)$ where T is temperature after T minutes.
Separate by dividing both sides by T - 75 to get $\dfrac{dT}{T - 75} = k dt$ . Integrate both sides to get $\ln|T - 75| = kt + C$ .

Since $T(0) = 185$ , we solve for C:
$|185 - 75| = k(0) + C\ \Rightarrow\ C = \ln 110$
So we get $\ln|T - 75| = kt + \ln 110$ . Use T(30) = 150 to solve for k:
$\ln| 150 - 75 | = 30k + \ln 110\ \Rightarrow\ \ln 75 - \ln 110= 30k \Rightarrow \\ k= \frac{1}{30}\ln (75/110) = \frac{1}{30}\ln(15/22)$

So

$\ln|T - 75| = kt + \ln 110 \Rightarrow |T - 75| = e^{kt + \ln110} \Rightarrow \\ \\
|T - 75| = 110e^{kt} \Rightarrow T - 75 = \pm110e^{(1/30)\ln(15/22)t} \Rightarrow \\
T = 75 \pm110e^{(1/30)\ln(15/22)t}$

But choose Positive because T > 75. Temp of turkey can't go under.

$T(t) = 75 + 110e^{(1/30)\ln(15/22)t} \\
T(45) = 75 + 110e^{(1/30)\ln(15/22)(45)} = 136.929 \approx 137{}^{\circ}F$

(b)

$T(t) = 75 + 110e^{(1/30)\ln(15/22)t} = 75 + 110(15/22)^{t/30} \\
100 = 75 + 110(15/22)^{t/30} \\
25 = 110(15/22)^{t/30} 
\frac{25}{110} = (15/22)^{t/30} \\
\ln(25/110) / ln(15/22) = t/30 \\
t = 30\ln(25/110) / ln(15/22) \approx 116\ \mathrm{min}$
