In circle O, m∠R = 30.8°. Find m∠NOQ.
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].

Twice the sum of a number and -6 equals -6 times the sum of the number and 4. Let n stand for the number. Solve for n.
Answer:
n = -18/7
Step-by-step explanation:
Represent the number with n.
Then:
n - 6 = -6(n + 4)
Performing the indicated multiplication, we get:
n - 6 = -6n - 24
Combining like terms results in 7n = -18, so n = -18/7

The sum of two circles is 80 pi square meters. Find the length of the radius if one of them is twice as long as the other
Answer:
Length of Radius of large circle= 8
Lenght radius of first circle= 2
Step-by-step explanation:
THIS IS THE COMPLETE QUESTION
The sum of the areas of two circles is 80π square meters. Find the length of a radius of each circle if one of them is twice as long as the other.
What is the radius of the larger circle?
Area of a circle can be calculated by Below formula
A = πr^2............eqn(1)
Let ( X) = area of first circle
Y= the area of second circle
Rx= radius of first circle
Ry = radius of second circle
From the question, we know that
[X+ Y] = 80π .......eqn(2)
Substitute the radius formula for the area,
[π(Rx)^2 + π (Ry)^2] = 80π ......eqn(3)
But from the question, Radius of second circle is twice of the second one, then
Ry = 2Rx ..........eqn(4)
If we substitute eqn (4) into eqn(3)
[ π(Rx)^2 + π (2Rx)^2 = 80π
If factorize π out, then cancel it out
π[(Rx)^2 + π (2Rx)^2 = 80π
Then we have
(Rx)^2 + 4(Rx)^2 = 80
5(Rx)^2 = 80
(Rx)^2= 80/5
(Rx)^2= 16
(Rx)= 4
From eqn(4)
Ry = 2Rx
Ry= 2(4)
Ry= 8
Rx= 2 and Ry= 8
Hence, radius of first circle= 2
Lenght Radius of second circle= 8

m<1 + 43 + 56 = 180
m<1 + 99 = 180
m<1 = 81
m<4 + 43 = 180
m<4 = 137

area of the figure= 58.3ft².
Please help me. I have been stuck for 45 minutes
Answer:
See photo.
Step-by-step explanation:
First, you need to find an already complete row, column, or diagonal and find its sum. This is the value that every other row, column, and diagonal needs to add up to. Next, find one that has two values filled in. Add these two numbers. Subtract them from the sum. The number you get is what needs to be in open box of that row/column/diagonal. Then you'll have another with two values, and you do the same thing for that one, and continue.
Example: 0+7+2= 9 so the sum for the left one is 9. you have a column with a 7 and a 3. 7+3= 10. 9-10= -1. then look at the diagonal. you have 2 and 3. 2+3=5, 9-5=4 so 4 is that one. and so on.

solve the inequality -3x - 7 = or < 8
Step-by-step explanation:
Isolate x.
7
−
8
x
>
19
−
7
Add
7
to
−
7
to cancel it out because it is the lowest number here.
But you do to one side what you do to the other, so add
7
to the positive
7
on the other side. You should now have:
14
−
8
x
>
19
Now, subtract
14
from
14
to cancel it out and do the same to the other side
(
19
)
. Now, you should have:
−
8
x
>
5
Now, to isolate
x
,
divide by
−
8
.
But remember when you divide or multiply an inequality by a negative value, the sign changes around.
−
8
x
−
8
<
5
−
8
Because you divided by a negative, the sign flips:
x

8
Answer: x [tex]\geq[/tex] -5
Step-by-step explanation:
-3x - 7 [tex]\leq[/tex] 8
add 7 to both sides
-3x [tex]\leq[/tex] 15
divide both sides by -3, you also have to flip the inequality sign because you are dividing by a negative.
x [tex]\geq[/tex] -5

There is a bag containing 10 red, 10 blue, and 10 yellow pieces of paper. Each paper color is numbered from 1 to 10. How would you express the probability that you select a blue piece of paper given that it has a number 10 on it?
A. P(blue)
B. P(10)
C. P(blue|10)
D. P(10|blue)
Answer:
D. P(10|blue)
Step-by-step explanation:
The correct expression for the probability of selecting a blue piece of paper given that it has the number 10 on it is:
C. P(blue|10)
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Here, "blue|10" means "blue given 10," which represents the conditional probability of selecting a blue paper given that the selected paper has the number 10 on it.
The formula for conditional probability is:
P(A|B) = P(A and B) / P(B)
In this case, A represents the event of selecting a blue piece of paper and B represents the event of selecting a paper with the number 10 on it.
We know that there are 10 blue pieces of paper and each color has 10 numbered pieces, so the total number of papers is 10+10+10=30.
Thus, the probability of selecting a paper with the number 10 on it is:
P(B) = 3/30 = 1/10
Out of the 10 blue pieces of paper, only one has the number 10 on it. Thus, the probability of selecting a blue piece of paper given that it has the number 10 on it is:
P(A and B) = 1/30
Therefore, the probability of selecting a blue piece of paper given that it has a number 10 on it is:
P(blue|10) = P(A and B) / P(B) = (1/30) / (1/10) = 1/3

Answer:

Step-by-step explanation:
The formula for slope is y2-y1/x2-x1.
So the y2 is 7 and the y1 is 2. The x2 is 10 and the x1 is 5. So when you plug those in you have 7-2/10-5. That simplifies to 5/5 which is 1.

Answer:
A = (5, 4)
B = (4, 3)
C = (5, 2)
D = (6, 3)
Step-by-step explanation:
Before I do anything, I will write the figure's coordinates for ABCD
A = (2, 3)
B = (1, 2)
C = (2, 1)
D = (3, 2)
Now, a translation means adding and or subtracting the x and y coordinates within the ordered pairs.
3 units right means add 3 units to the value of coordinate x. Coordinate x will always be for any horizontal movement (left and right).
1 unit up means add 1 unit to the value of coordinate y. Coordinate y will always be for any vertical movement (up and down).
Make these adjustments to each ordered pair:
A = (2 + 3, 3 + 1)
A = (5, 4)
B = (1 + 3, 2 + 1)
B = (4, 3)
C = (2 + 3, 1 + 1)
C = (5, 2)
D = (3 + 3, 2 + 1)
D = (6, 3)
Unfortunately I cannot graph the points for you, but if you mark each ordered pair I've given and then connect them together with lines, it will be graphed.
