Answer:
B) 13
Step-by-step explanation:
Average age means to calculate mean:
Mean = (Sum of all numbers)/(Number of numbers)
Mean = (14 + 14.5 + 12 + 11.5 + 15 + 13 + 10.5 + 13.5)/8
Mean = (104)/8
Mean = 13

In ΔOPQ, q = 110 inches, o = 970 inches and ∠P=167°. Find the area of ΔOPQ, to the nearest square inch.
Answer:
[tex]Area = 12004[/tex] square inches
Step-by-step explanation:
Given
[tex]q = 110[/tex]
[tex]o = 970[/tex]
[tex]\angle P =167[/tex]
Required
The area of the triangle
To do this, we use:
[tex]Area = \frac{1}{2} * o * q * sin(P)[/tex]
So, we have:
[tex]Area = \frac{1}{2} * 970 * 110 * sin(167^\circ)[/tex]
[tex]Area = \frac{1}{2} * 970 * 110 * 0.2250[/tex]
[tex]Area = 12003.75[/tex]
Approximate
[tex]Area = 12004[/tex]

3RD TIME ASKING PLS HELP
The angles surrounding the point p are 90 degrees
Then using the angle given, find the missing angles.
JPH = 90
HJP = 49
90+49 = 139
180 - 139 = 41
Therefore JHP = 41
HLP = HJP = 49
HLP = 49
KLP = 72
KLP + HLP = 72 + 49 = 121
Therefore, HLK = 121
LP = JP = 16
JP = 16
HL = HJ = 13
HL = 13
Hope this helps! =)

If my initial angle is 30 degrees, what is the negative coterminal angle?
Answer:
Step-by-step explanation:
Coterminal angles are angles in standard position (angles with the initial side on the positive x -axis) that have a common terminal side. For example 30° , −330° and 390° are all coterminal.
Answer:
-330°Step-by-step explanation:
Coterminal angles have a difference of 360° or multiples of 360°.
Negative coterminal angle with 30° is:
30° - 360° = -330°Which three lengths could be the lengths
of the sides of a triangle?
A. 4 cm, 8 cm, 13 cm
B. 13 cm, 11 cm, 23 cm
C. 5 cm, 18 cm, 12 cm
D. 25 cm, 8 cm, 16 cm
Given:
The three lengths in the options.
To find:
Which three lengths could be the lengths of the sides of a triangle?
Solution:
If the sum of two smaller sides is greater than the largest side, then the three sides can form a triangle otherwise the triangle is not possible.
In option A, the three sides are 4 cm, 8 cm, 13 cm. Here, the largest side is 13 cm.
Sum of two smaller sides is:
[tex]4+8=12[/tex]
[tex]4+8<13[/tex]
So, the triangle is not possible.
In option B, the three sides are 13 cm, 11 cm, 23 cm. Here, the largest side is 23 cm.
Sum of two smaller sides is:
[tex]13+11=24[/tex]
[tex]13+11>23[/tex]
So, the triangle is possible.
In option C, the three sides are 5 cm, 18 cm, 12 cm. Here, the largest side is 18 cm.
Sum of two smaller sides is:
[tex]5+12=17[/tex]
[tex]5+12<18[/tex]
So, the triangle is not possible.
In option D, the three sides are 25 cm, 8 cm, 16 cm. Here, the largest side is 25 cm.
Sum of two smaller sides is:
[tex]8+16=24[/tex]
[tex]8+16<25[/tex]
So, the triangle is not possible.
Therefore, the correct option is B. The three lengths 13 cm, 11 cm, 23 cm could be the lengths of the sides of a triangle.

A door is fixed at the point O. Ben opened it by an angle of 30°. The area swept by the door was {25}{12}\pi\
Answer:
5 units
Step-by-step explanation:
Area swept by the floor will be the area ofd a sector
Area of a sector = theta/2π * πr²
We are to find the radius r
Given
Area= 25π/12
theta = 30° = π/6
Substitute
25π/12 = 30/360 * πr²
25π/12 = 1/12 * πr²
25/12 = r²/12
r² = 25
r = √25
r = 5
Hence the radius od the part swept by the door is 5 units

The diameter of a circle is 14 ft.
What is the area of the circle in terms of π?
Answer:
49π ft²
Step-by-step explanation:
[tex]A=\pi r^2[/tex] where r is the radius of the circle
To find the radius, divide the diameter by 2:
14 ft ÷ 2 = 7 ft
Plug the radius 7 ft into the equation
[tex]A=\pi (7)^2\\A=49\pi[/tex]
Therefore, the area of the circle in terms of pi is 49π ft².
I hope this helps!
Answer:
49π
Step-by-step explanation:
Diameter=14
Radius=14/2=7
Area=πr squared
Area=7 squared π
Area=49π

Jackson said that he made a triangle that had side lengths of 6 units, 6 units and 14 units. Is this a possible triangle?
Answer:
The triangle will not be possible.
this is because two side lengths can't expand 14 units.
in order for the triangle to work, the sum of the two short side lengths must be greater than the longer side.
however, 6+6 does not equal 14 it equals 12 this means that the triangle is not possible

The perimeter of a photograph is 34 inches. It is 10 inches long. How wide is it?
inches
Answer:
the width of the photo is W = 14" / 2, or 7"
Step-by-step explanation:
Recall that P = 2W + 2L. Here L = 10" and P = 34".
Thus, 2(10") + 2W = 34", or
2W = 14"
Then the width of the photo is W = 14" / 2, or 7"
