Answer:
a. y=8-x
Step-by-step explanation:
Answer:
B , E
Step-by-step explanation:
A monomial has only 1 term and both the options of B and E are the only one that has one term, which means there is no other addition, subtraction, division, or multiplication in the term.
Equations A will find the height of the lighthouse. Option A is correct.
<h3>What is trigonometry?</h3>
Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.
(d)distance from the boat to the lighthouse =115 meters
Θ is the angle of elevation = 42"
h is the height
Apply the tangent formula in the obtained triangle;

The equations will find the height of the lighthouse is;

Hence, option A is correct.

Hello!
You have to first find the percentage of the tv's are defective
3/11 = 0.27
27% of the tvs are defective
the probability of one of the tv's working is 8/11
the probability of the second tv working is 7/10
You multiply these together
8/11 * 7/10 = 28/55
There is a 28 out of 55 chance both tvs work
There is a 3/11 probability that one of the tvs does not work
Hope this helps!
