Answer:
5
Step-by-step explanation:
5 x 2 is 10 and 48 plus 10 is 58
Answer:
None
Step-by-step explanation:
The sum of the angles of every triangle must add up to 360 degrees. 80+80+20=200, thus no triangle can be constructed with these angles.
This can be solved using the formula for t test which is = x - mu over standard deviation divided by the square root of the number of samples. In this case, it is 1185 - 1200 over 70 divided by square root of 100 which give us a value of 2.14 which is equal to .9839 in area. Only rarely, just over one time in a hundred tries of 100 light bulbs, would the average life exceed 1200 hours.
Exponential functions can be expressed as:
f=ir^t, f=final value, i=initial value, r=rate or common ratio, t=term number or "time" when it is fractional...In this case we have:
f=100((100-11)/100)^x
f=100(0.89)^x and we want to solve for when f=15 so
15=100(0.89)^x
Answer:
The height of the hill is of 9.19 miles.
Step-by-step explanation:
Relations in a right triangle:
The sine of an angle is given by the measure of the opposite side divided by the hypotenuse.
The cosine of an angle is given by the measure of the adjacent side divided by the hypotenuse.
In this question:
Angle of 45º, and drives 13 miles. Due to the inclination, this represents the hypotenuse.
The height is the opposite side. So
We have that 
The height of the hill is of 9.19 miles.
