Half a number x minus 5 is 11

Mathematics
1 answer:
ASHA 777 [7]3 years ago
6 0

Answer:

1/2x - 5 = 11

x = 28

Step-by-step explanation:

This is the answer because:

1) 1/2 a number means to multiply a number (x) to get half of the number. Therefore, we have to multiply 1/2 with x

2) Next, it says minus 5 which means to subtract 1/2x with 5

3) Finally, it says all of this equal to 11, so the final equation would be

1/2x - 5 = 11

4) x = 28 because half of 28 is 14. 14 minus 5 is equal to 11.

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

The Drop Rate Of A Item Is 0.01% to get one, but there are 2 other items with the same drop rate. so there are 3 items with a dr
Bumek [7]

Answer:

If you hope to get the rare Deathcharger's Reins mount from Baron Rivendare for example, we know that it has a 1% drop chance. That means that every time you kill the Black Baron you have a 1% chance of getting the mount. 1% on the first kill, and 1% on the 100th kill. However, over the course of 100 kills, you have a much higher probability of getting the mount. But not 100%. Never 100%.

Which set of side lengths form a right triangle?
astraxan [27]
Since we don't want to use the Pythagorean Theorem on all of these, first we look for some Pythagorean Triples. Its very helpful to know some of the common ones, so here's a list:

3, 4, 5
5, 12, 13
7, 24, 25
8, 15, 17

So we either look for these or a multiple of these numbers.

The last one is the only one that fits because 15, 20, 25 is a multiple of the triple 3, 4, 5 by multiplying all of them by 5. 

Thus, 15, 20, 25 forms a right triangle.
