Given:
In circle O, m∠R = 30.8°.
To find:
The m∠NOQ
Solution:
Central angle theorem: According to this theorem, the central angle is always twice of subtended angle on the same arc.
Angle NOQ and angle NRQ are on the same arc but ∠NOQ is the central angle and ∠NRQ is the subtended angle on the arc NQ.
Using central angle theorem, we get
[tex]m\angle NOQ=2\times m\angle NRQ[/tex]
[tex]m\angle NOQ=2\times m\angle R[/tex]
[tex]m\angle NOQ=2\times 30.8^\circ[/tex]
[tex]m\angle NOQ=61.6^\circ[/tex]
Therefore, [tex]m\angle NOQ=61.6^\circ[/tex].

A 602.88
B 150.72
C 50.24
D 301.44
Answers
Answer:
A
Step-by-step explanation:
The base of your cylinder has a radius of 4 cm, its area is 16 × 3.14, or 50,24 square centimeters. If that same cylinder is 12 cm tall, its volume is 50,24 × 12 = 602,88 cubic centimeters.

Answers
Answer:
Below
Step-by-step explanation:
False, negative times negative is always positive.
True, 10,000 is less than 99,999, so subtracting them will be negative.
False, 34 and 43 aren't equal to eachother so subtracting them can't end up to 0.
False. If you follow PEMDAS, you have to do multiplication first. In the left side, -80(30) is a negative value, while in the right, (-30)(-80) is a positive value.
Mr. Garcia deposited $2,500 in a new account at his bank.
The bank pays 6.5% interest compounded annually on this account.
Mr. Garcia makes no additional deposits or withdrawals.
Which amount is closest to the balance of the account at the end of 2 years?
A.$2,513.00
B.$2,662.50
C.$2,835.56
D.$2,825.00
Answers
Answer:
$2,825.00
Step-by-step explanation:
First, I found out what 6.5% of 2,500 is, so 6.5% x 2,500 = 162.5 . Then I did 162.5 x 2, which equals 325. I then added 325 to 2,500 and got 2,825.

Tonys backyard is in the shape of a trapezoid the bases of the backyard or 30 feet and 50 feet long area of the backyard is 960 ft.² sold in equation to find the height of Christophers backyard A=12(b1+b2)h
Answers
Answer:
24 feets
Step-by-step explanation:
Area of a trapezium :
A=1/2(b1+b2)h
b1 = 30 ; b2 = 50 ; Area, A = 960ft²
Inputting values into the formula :
960 = 1/2(30 + 50) * h
960 = 1/2(80)h
960 * 2 = 80h
1920 = 80h
Divide both sides by 80
1920 / 80 = 80h / 80
24 = h
Height of backyard = 24 feets

PLEASE HELP Adam has a rectangular swimming pool. He fills it with water to a depth of 5 feet. The water has a VOLUME of 1200 cubic feet.
Answers
Step-by-step explanation:
Given that,
The depth of the pool is, h = 5 feet
Volume of the pool, V = 1200 cubic feet
We need to find the possible values for the dimensions of the pool. We know that the volume of a rectangle is given by :

A bird enclosure at a zoo was initially housed with 350 birds. The total population of birds in the enclosure is expected to increase every year by 5%.
Which function accurately describes the population of the birds in the enclosure, f(x), after x years?
A. f(x)=350(1.05)^x
B. f(x)=1.05(350)^x
C. f(x)=350(1.5)^x
D. f(x)=1.5(350)^x
Answers
Answer:
A
Step-by-step explanation:
The initial population is 350 so...
P = 350
The total population of birds in the enclosure is expected to increase every year by 5%
so r = 0.05
and time = X
we need to use the equation P(X) = P(1+r)^x
so by plugging in the values we get:
P(x) = 350(1.05)^x
so A is the correct answer

Answer:

Step-by-step explanation:
When you are given a right triangle with a given angle and side, you can use
trigonometric functions to calculate missing side lengths or inverse functions for angles based on this information.
These ratios can be remembered by the mnemonic:
SOH CAH TOA.
S O H → Sin (Sine) = Opposite / Hypotenuse
C A H → Cos (Cosine) = Adjacent / Hypotenuse
T O A → Tan (Tangent) = Opposite / Adjacent
______________________________________
The Opposite side is the side directly across from the angle, The adjacent (next to) side is the side other than the hypotenuse or opposite side, and the hypotenuse is the longest side.
Given that we are trying to find the adjacent side, we must use the cos (cosine) function because that can be multiplied by the hypotenuse to give us the adjacent side we are looking for.
Therefore, 36 [Hypotenuse Side] × cos(72°) = Adjacent Side.
Because: 36 = Hypotenuse Side.
cos(72)° = Adjacent Side / Hypotenuse Side.
36 × cos(72°) =
36 × 0.309016994374... = 11.12461179749... ≈ 11.1

The perimeter of a rectangular swimming pool is 154 m. Its length is 2 m more than twice its breadth. What are the length and the breadth of the pool?
Answers
Answer:
Length of the pool = 52 m
Width of the pool = 25 m
Step-by-step explanation:
Perimeter of rectangular pool = 154 m
Let the length of rectangular pool = l m
And width of the rectangular pool = w m
Formula, to calculate the perimeter of a rectangle is given by,
Perimeter = 2(Length + width)
By substituting values in the formula,
154 = 2(l + w) --------(1)
Since, "length of the pool is 2 m more than twice of its breadth"
l = 2 + 2w ---------(2)
Bu substituting value of 'l' from equation (2) to equation (1),
154 = 2[(2 + 2w) + w]
154 = 2(3w + 2)
77 = 3w + 2
3w = 75
w = 25 m
From equation (2),
l = 2 + 2(25)
l = 2 + 50
l = 52 m
Therefore, length of the rectangular pool is 52 m and width is 25 m.
Shona has to draw the line with equation y = 3x + 2. Here is her line. Explain why Shona's line cannot be correct.
Answers
Answer:
Step-by-step explanation:
The y intercept cannot possibly where it is shown. The slope is correct. The line is going from the lower left to the upper right, and the 3 makes the line closer to the y axis. For example if x = 1 then y = 3*1+2 = 5.
If x = 2, then y = 3*2 + 2 = 8 so each move of x makes a huge difference in where y is.
So lets go back to the y intercept. When x = 0, then y = 2. y = 2 is about the x axis, not below it.
Shona's drawn line cannot be the representation of her equation y = 3x + 2, as the y-intercept of her drawn line is negative, while the y-intercept of the equation is positive (b = 2).
What does the equation of a line imply?The equation of a line of the form y = mx + b shows a line on the coordinate plane, where for every value of x, we get a particular value of y, and m is the slope of the line. The slope is the value of tan θ, where θ is the positive angle formed between the x-axis and the line. b is the y-intercept. The y-intercept is the value of y when x = 0. This signifies that the line passes through the point (0, b).
How do we solve the given question?We are given an equation of a line y = 3x + 2, and a line of the coordinate plane.
We are asked to give the reason why the line on the plane is not the representation of the given equation.
The equation y = 3x + 2, when compared to the slope-intercept form of a line, y = mx + b, shows that the slope m = 3 and the y-intercept b = 2.
The line on the plane has a positive slope, so m = 3 can be its slope.
But the y-intercept of the drawn line is negative since it is below the origin. So b = 2 cannot be its y-intercept.
(Value of y is positive above the origin and negative below the origin)
(Value of x is positive to the right of the origin and negative to the left of the origin)
∴ Shona's drawn line cannot be the representation of her equation y = 3x + 2, as the y-intercept of her drawn line is negative, while the y-intercept of the equation is positive (b = 2).
