Answer:
c) 82
Step-by-step explanation:
<ABE and <BEC are supplementary because they form a line.
<ABE + <BEC = 180
116+ x = 180
Subtract 116 from each side.
116-116+x = 180 -116
x = 64
The angles in triangle ECB add to 180 because it is a triangle
<BEC + <ECB + <CBE = 180
x + 34+y = 180
64 + 34+ y = 180
98 + y = 180
Subtract 98 from each side.
98-98+y = 180-98
y = 82
Answer:
None of these answers are correct.
Step-by-step explanation:
If a²+b²=c², then 7²+5²=c², then if you solve for c this equals about 8. This is none of the answers mentioned which is 8. Also, a good thing to remember is that the hypotenuse is always larger than the two side lengths. So, since the answer is 8 then it is none of the answers.
The number of people who took ride in the big ferris wheel at a fair can be calculated by proper dimensional analysis. This can be done through the equation below,
n = (number of minutes)(rate at which the chair passes the exit platform)(number of persons per chair)
Substituting the known values to the equation,
n = (30 minutes)(1 chair / minute)(2 persons / chair)
n = 60 persons
Answer: 60 persons
Step-by-step explanation:
Supplementary angles add up to 180 degrees
Let x represent the smaller angle:
x + (x + 81.2) = 180
2x + 81.2 = 180
2x = 98.8
x = 49.4 degrees
therefore:
smaller angle = 49.4 degrees
larger angle = 49.4 + 81.2
= 130.86 degrees
We will need to shade the region above f(x) and the region below the function g(x).
<h3>How to transform the graph into the solution set?</h3>
We have:
f(x) = x² - 2
g(x) = -x² + 5
Both of these are already graphed, and we want to transform it into:
y > f(x)
y ≤ g(x)
The first inequality means that we need to graph f(x) with a dashed line, because f(x) is not part of the solution, and then we shade all the region above f(x).
For the other inequality, we use a solid line (because the points on the line are solutions) and then we shade the part below the curve.
