in the diagram O is the center of the circle XY is a diameter
help and explain please
also giving a BRAINLIEST!
Answers
Answer:
see explanation
Step-by-step explanation:
The angle at the circumference b , is half the angle subtended at the centre by the arc XZ, that is
b = 0.5 × 72 = 36
OZ and OX are congruent ( both radii of the circle )
Thus Δ OXZ is isosceles with base angles congruent, thus
a = [tex]\frac{180-72}{2}[/tex] = [tex]\frac{108}{2}[/tex] = 54
∠ XZY = 90° ( angle in a semicircle is right )

A telephone poll asked people whether they like playing golf. Of the 100 people polled,20 like playing golf. What percentage of the people like playing golf?
Answers
Given:
Of the 100 people polled, 20 like playing golf.
To find:
The percentage of the people who like playing golf.
Solution:
In the poll,
Total number people = 100
Who like playing golf = 20
Now, percentage of the people who like playing golf is
[tex]Required \%=\dfrac{\text{Number of people who like playing golf}}{\text{Total number people in poll}}\times 100[/tex]
[tex]Required \%=\dfrac{20}{100}\times 100[/tex]
[tex]Required \%=20[/tex]
Therefore, 20% of the people like playing golf.

please help find equation in slope intercept form
Answers
Answer:
y= -3x-2
Step-by-step explanation:
1. Take any two points from the line
• (1, -5) (-2, 4)
2. Use the equation: y2-y1 / x2-x1 to find the slope
4- (-5) / -2-1
= 9/-3
= slope is -3
3. Find the y intercept
y= -2
Find the slope of the line that passes through each pair of points
Answers
Answer:
-3
Step-by-step explanation:
Start at the y-intercept which is 1, and go down however many times it would take, for you to go across and get to a point. Basically to find the slope is rise over run. In this case you would "rise" -3 and run 1. I haven't done this in awhile. If its wrong, I apologize. Have a good night.

The answer is A
Step-by-step explanation:
The line is perpendicular to RS through S
There are several constructions that can be done with the straightedge and the compass.
The statement that describes the figure Kelly is constructing is: (c) a line parallel to RS through Q
From the figure, we have the following observations
Two arcs intersect on line RSAnother set of two arcs intersect on the same level as point Q.When a line is drawn from point Q through the intersection of these lines, the line would be parallel to line RS.
Hence. we can conclude that:

An employee’s hourly raise went up from $11 per hour to $16 per hour. What is the rate of increase? Round to the nearest percentage.
Answers
Answer:
45%Step-by-step explanation:
Step one:
given data
intial pay= $11 per hour
final pay= $16 per hour
Required
% increase
Step two:
%increase= final-initial/initial*100
substitute
%increase= 16-11/11*100
%increase=5/11*100
%increase= 0.45*100
%increase= 45%
Hence the percent raise is 45%
Given the replacement set:

Which inequality is true?
b−6>10.4
b+6<10.4
b−8≥12.4
b+8≥12.4
Answers
Answer:
b+8≥12.4
Step-by-step explanation:
Here, we want to select the correct option
From what we have here;
b ≥12.4-8
b ≥ 4.4
Looking at the range of values in the set
We can see that the smallest of values is 4.4
This tells exactly the correctness of the last option as the values of b are 4.4 or greater
A cake recipe calls for 1.5 cups of milk and 3 cups of flour. Seth made a mistake and used 5 cups of flour. How many cups of milk should he use to keep the proportions correct
Answers
Answer:
2.5cup of milkStep-by-step explanation:
Step one:
we are told that the ratio of milk to flour is 1.5cups to 3 cups
in other words, to prepare cake we need 1.5 cup of milk and 3 cups of flour
if we use 5 cups of flour we can balance up using the relation below
1.5cups of milk require 3 cups of flour
x cups of milk require 5 cups of flour
cross multiply we have
x=1.5*5/3
x=7.5/3
x=2.5cup of milk

Isabel is pulling water up from an old-fashioned well. She lifts the bucket of water at a rate of 4 ft/s, and after 1 s, the bucket is 1 ft below the top of the well. What is the equation in point-slope form of the line that represents the height of the bucket relative to the top of the well?
Answers
Answer:
The equation in point-slope form of the line that represents the height of the bucket relative to the top of the well is [tex]y + 1 = 4\cdot (t-1)[/tex].
Step-by-step explanation:
The point-slope form of the equation of the line is represented by the following expression:
[tex]y - y_{o} = m\cdot (t-t_{o})[/tex] (1)
Where:
[tex]t[/tex] - Time, measured in seconds.
[tex]y[/tex] - Height below the top of the well, measured in feet.
[tex]t_{o}[/tex], [tex]y_{o}[/tex] - Known information of the well, measured in seconds and feet, respectively.
[tex]m[/tex] - Slope, measured in feet per second.
If we know that [tex](t_{o},y_{o}) = \left( 1\,s, -1\,ft\right)[/tex] and [tex]m = 4\,\frac{ft}{s}[/tex], then the equation in point-slope form of the line is:
[tex]y + 1 = 4\cdot (t-1)[/tex]
The equation in point-slope form of the line that represents the height of the bucket relative to the top of the well is [tex]y + 1 = 4\cdot (t-1)[/tex].
An angle measures 48° more than the measure of its complementary angle. What is the
measure of each angle?
Answers
Answer:
The angles measure 21 degrees and 69 degrees.
Step-by-step explanation:
Complementary angles have a sum of 90 degrees when added together.
Let's call the complementary angle x. We can write the angle that we're looking for as in terms of x as x + 48.
Since these angles must sum to 90 we can write the equation and solve:
x + x + 48 = 90
2x + 48 = 90
2x + 48 - 48 = 90 - 48
2x = 42
x = 21
x + 48 = 69
21 degrees and 69 degrees.
Answer:
69° and 21° is the answer.
