In circle O, the length of radius OL is 6 cm and the length of arc LM is 6.3 cm. The measure of angle MON is 75°
Answer:
14.2cm
Step-by-step explanation:
Complete question:
In circle O, the length of radius OL is 6 cm and the length of arc LM is 6.3 cm. The measure of angle MON is 75°.
Rounded to the nearest tenth of a centimeter, what is the length of arc LMN?
Find the diagram attached
arc LN= arc LM + arc MN
First we need to get the arc MN
length of an arc = theta/360 * 2πr
length of arc MN = 75/360 * 2(3.14)(6)
length of arc MN = 0.20833*37.68
length of arc MN = 7.85
Hence;
arc LN = 6.3 + 7.85
arc LN = 14.15cm
Hence the length of arc LN is 14.2cm

i neex help on a equation
Answer:
-24a^10
Step-by-step explanation:
Given the equation −4a^5⋅6a^5
This can also be written as
−4a5⋅6a^5
= (-4*6)(a^5*a^5)
= -24(a^{5+5})
= -24a^10
Hence the required expression is -24a^10
AB and CD are straight line segments.
∠ AOE = 50° and ∠ DOB = 95°.
Find the values of the following angles giving a reason for each answer in the comment box.
The diagram is not drawn accurately.
i) obtuse ∠ AOC
ii) acute ∠ BOC
iii) acute ∠ DOE
Answer:
i) Angle AOC is 95° Reason:- Angle AOC is equal to Angle DOB since they are Vertically Opposite Angles.ii) Angle BOC is 85° Reason:- Angle AOC + Angle BOC - 180° (they lie in a straight line so they are a linear pair. Sum of the angles will be 180°) Angle AOC is 95°, So:- 95° + Angle BOC = 180° Angle BOC= 180° - 95° Angle BOC = 85° iii) Angle DOE is 17° Reason:- Angle AOE+ Angle DOE+ Angle DOB = 180° (they lie in a straight line so they're a linear pair. Sum of the angles will be 180°) So, 68° + Angle DOE+ 95° = 180° 163° + Angle DOE = 180° Angle DOE= 180° - 163° Angle DOE is 17°
whats the measure of angle E ?
Answer:
57degrees
Step-by-step explanation:
The triangle is an isosceles triangle, hence m<D = m<E (base angles are equal)
Taking the sum of the angles and equating to 180
5x-4 + 4x+1 + 4x+1 = 180
5x+4x+4x-4+1+1 = 180
13x - 2 = 180
13x = 180 + 2
13x = 182
x =182/13
x = 14
Get m<E
m<E = 4x+ 1
m<E = 4(14)+ 1
m<E = 56+1
m<E = 57degrees
Hence the measure of m<E is 57degrees
Find the volume of the cube shown at the right. h=6in
Answer:
216 in³
Step-by-step explanation:
The volume of a rectangular prism is length x width x height
A cube is a special rectangular prism in which all the edges are the same length (like a square)
To find the volume of a cube given the height 6 just solve 6·6·6=216
Don't forget your units and since you cubed 6 inches, they are now in³ or inches cubed

Shellac O'Lean, a freshman on your school's football team, is 6 ft tall and weighs 140 lb. Since he would rather play basketball, he plans to grow to 7 ft 1 in., the same height as Shaquille O'Neal, his idol. If Shellac scales geometrically as he grows, how much can he expect to weigh? (O'Neal weighs 325 lb. Round your answer to the nearest whole number.)
Answer:
At 7 ft. 1 in., Shellac can expect to weigh approximately 165 lb
Step-by-step explanation:
The relationship between the heights and the weights of the freshman are presented as follows;
The weight of the freshman at 6 ft. = 140 lb
The height to which he plans to grow = 7 ft. 1 in.
Given that Shellac scales geometrically as he grows, then the height to weight ratio is constant
Let 'y' represent Shellac's weight when his height is 75 ft. 1 in., we have;
[tex]\dfrac{6 \, ft.}{140 \ lb} = \dfrac{7 \, ft. \ 1 \, in. }{y}[/tex]
6 ft. = 72 in.
7 ft. 1 in. = 85 in.
Therefore, we get;
[tex]\dfrac{72 \ in.}{140 \ lb} = \dfrac{85 \ in. }{y}[/tex]
[tex]y ={85 \ in. }\times \dfrac{140 \, lb}{72 \ in.} = 165.2 \overline 7 \, lbs[/tex]
Shellac's expected weight given to the nearest whole number when his height is 7 ft. 1 in. ≈ 165 lb.
Vincent gathered groups of 1 to 8 people and gave every group the same puzzle to solve. He recorded the
number of minutes it took each group to solve the puzzle and plotted the results.
Which statement is the best description of the association between these variables?
The statement that best describes the association of these variables is larger groups tend to take less time to solve the puzzle.
What is the true statement?A graph can be described as a pictorial representation of data. A graph has a x axis and a y-axis. The x-axis in this graph is the number of people in the groups and the y-axis is the time it takes to solve the puzzle.
The graph slopes downwards. This indicates that as the number of people in the groups increase, the time it takes to solve the puzzle decreases.

Sierra has plotted two vertices of a rectangle at (3,2) and (8,2). What is the length of the sides of the rectangle
Answer:
5units
Step-by-step explanation:
Given the two vertices of a rectangle at (3,2) and (8,2). We are to calculate the distance between the two points.
Using the formula
D = √(x2-x1)²+(y2-y1)²
D = √(2-2)²+(8-3)²
D = √0+5²
D = √25
D = 5
Hence the length of the side of the rectangle is 5units

What is the area and perimeter of the equilateral triangle? Round your final answer to the nearest tenth of a square unit.
Answer:
In general, the height of an equilateral triangle is equal to √3 / 2 times a side of the equilateral triangle. The area of an equilateral triangle is equal to 1/2 * √3s/ 2 * s = √3s2/4. 2 ways to find the area of a triangle using Pythagorean Theorem? 1. Using Pythagorean theorem. The basic formula for triangle area is side a (base) times the height h , divided by 2: area = (a * h) / 2 2.Using trigonometry. Let's start from the trigonometric triangle area formula: area = (1/2) * a * b * sin(γ) , where γ is the angle between sides.

Answer:
60.22in^2.
Step-by-step explanation:
First, find the area of the rectangle. 14.1x7=98.7.
Then, we need to find the area of the circle and subtract it from the area of the rectangle.
The area of the circle is pi*r^2. so, pi*3.5^2 is about 38.48. (The radius is half of the diameter, so the radius would be 3.5).
Since there are two halves of the circle, we can just subtract 38.48 from 98.7 so get the area of the shaded region. So, the area of the yellow area is 60.22in^2.
Find rectangle area: 14.1 x 7 = 98.7
Find areas of semicircles: a = 3.14(3.5)^2 = 76.96
Subtract area of semicircles: 98.7 - 76.96 = 21.74
Every seventh-grade student at Martin Middle School takes one world language class.
One-tenth of the seventh-grade students take French. Eighteen seventh-grade students take French.
Which equation represents s, the total number of seventh-grade students at the middle school?
18 = 0.1 s
18 = StartFraction 10 over s EndFraction
StartFraction s over 0.1 EndFraction = 18
10 s = 18
Option (A) 18 = 0.1s
Step-by-step explanation:
Every seventh-grade student at Martin Middle School takes one world language class.
Now we will form the equation as per statement of the question.
Let total students of seventh-grade = s
" one tenth of seventh grade students take French."
" Students who took French were 18."
So of s = 18
(0.1)s = 18
therefore, Option (A) 18 = 0.1s is the answer.
