Answer:

It is -6.

Step-by-step explanation:

7 + 12 is 19

b + (7 + 12) = 13

b + (19) = 13

-6 + 19 = 13

The answer you are looking for is b = -6.

There are 2 ways to find this. You could use...

Add together 7 and 12 to get 19, then subtract 19 from both sides to get b = -6. OR...
Subtract 12 from both sides to get b + 7 = 1, then subtract 7 from both sides to get b = -6.

Either way, you will get the same answer of b = -6. One method is just longer than the other. I hope this helps!

A) The differential equation comes from the fact that the rate of temperature change is proportional to the difference in temperatures.
$\frac{dT}{dt} = \alpha(T -52)$

B) Find general solution by separating variables and integrating $\int\frac{dT}{T-52} = \alpha \int dt \\ ln (T-52) = \alpha t + C \\ T = C e^{\alpha t} +52$ :

C) Initial condition is t=0, T = 87
$87 = C +52 \\ C = 35$

D) Total time elapsed is 10 minutes, new temperature is 84
$84 = 35 e^{10\alpha} +52$
solve for alpha
$e^{10\alpha} =\frac{32}{35} \\ \alpha = \frac{ln(32/35)}{10} \\ \alpha = -.00896$

E) Temperature function is:
$T = 35 e^{-.00896 t} +52$
solving for t
$t = \frac{ln (\frac{T-52}{35})}{-.00896}$
Plug in T = 98.6
$t = -31.95$

If 5/8ths is equal to $531.25 what is the remaining portion of the number.

Nimfa-mama [501]

5/8 = .625
531.25 / .625 = 850
850 - 531.25 = $318.75

Diego is making a circular table. He is cutting the largest circle possible from a piece of square wood with sides 6 feet long.

Flauer [41]

Area of wood = 6x6 = 36
area of circle = 3.14x9 = 28.26
left over = 36 - 28.26 = 7.74
