Answer:
A. 50
Step-by-step explanation:
Sum of interior angles of a triangle is always =180 °
Since this is a right triangle, therefore we know that one angle of the triangle measures 90°
Therefor sum of other two angles has to be =
One angle measures = 40°
Therefore the missing angle 

Answer:
82 degrees
Step-by-step explanation:
It took 3 hours for it to go from 78 to 72.
Which is a rate of -2 degrees per hour
We want to know what the temperature was two hours before it was 78 degrees so we'd do 78 - (-2) which is 82
plz clarify
Step-by-step explanation:
There is missing information about this question that I found online.
Given function is:

The question is:
<span>Is this exponential growth or decay? Explain using your understanding of the properties of exponents.
</span>This is an exponential decay.
In general, we can write down exponential functions like this:

Parameter a is the key parameter that will tell how exponential function behaves. If it is positive we have an exponential growth. If it is negative we can rewrite function like this:

We can notice that in this case, the denominator will exhibit exponential growth, in other words, the functions rapidly declines. This is an exponential decay.
Answer:
120
Step-by-step explanation:
20 * 5 = 100 so we multiply 24 by 5 and that equals 120
