Given that M is the midpoint of VW, what is the length of line segment VM?
4x-1 3x + 3
Answer:
VM = 15
Step-by-step explanation:
Given that line segment VM = 4x - 1
line segment MW = 3x + 3,
since M is the midpoint of VW, therefore:
VM = MW
Thus,
[tex] 4x - 1 = 3x + 3 [/tex]
Find the value of x
[tex] 4x - 3x = 1 + 3 [/tex]
[tex] x = 4 [/tex]
VM = 4x - 1
Plug in the value of x
[tex] VM = 4(4) - 1 = 16 - 1 = 15 [/tex]
VM = 15
find the area of a regular octagon with a perimeter of 80 ft and an apothem of 12.07 feet
Answer:
The area of a regular octagon with a perimeter of 80 ft and an apothem of 12.07 feet is 482.8 ft².
Step-by-step explanation:
An octagon is a polygon with eight sides. An octagon is regular (also called a regular octagon) is a polygon with all eight sides equal.
The apothem of a regular octagon is the shortest distance between the center and any of its sides, in other words, it is the distance that separates the center of the polygon from the central point of each side of the octagon.
The area is calculated using the following formula:
[tex]Area=\frac{n*L*Ap}{2}[/tex]
Where:
n is the number of sides. L is the length of one of the sides. Ap is the value of the apothem.Being n = 8 being an octagon and the perimeter P the sum of the sides of the octagon (P = 8 * L), the area of the regular octagon can be calculated by:
[tex]Area=\frac{P*Ap}{2}[/tex]
In this case:
P=80 ftAp=12.07 ftReplacing:
[tex]Area=\frac{80ft*12.07ft}{2}[/tex]
Solving:
Area=482.8 ft²
The area of a regular octagon with a perimeter of 80 ft and an apothem of 12.07 feet is 482.8 ft².

Which method and additional information would prove triangle ONP and triangle MNL similar by the AA similarity postulate?
A. Use rigid and nonrigid transformations to prove segment PN over segment MN equals segment LN over segment ON.
B. Use a rigid transformation to prove that angle NPO is congruent to angle NLM.
C. Use rigid and nonrigid transformations to prove segment PN over segment ML equals segment LN over segment ON.
D. Use a rigid transformation to prove that angle NLM is congruent to angle LMN.
Use a rigid transformation to prove that angle NPO is congruent to angle NLM
=====================================================
Explanation:
The AA stands for "angle angle". So we need two pairs of angles to prove the triangles to be similar. The first pair of angles is the vertical angles ONP and MNL, which are congruent. Any pair of vertical angles are always congruent.
The second pair of angles could either be
angle NOP = angle NMLangle NPO = angle NLMso we have a choice on which to pick. The pairing angle NOP = angle NML is not listed in the answer choices, but angle NPO = angle NLM is listed as choice B.
Saying angle NLM = angle LMN is not useful because those two angles are part of the same triangle. The two angles must be in separate triangles to be able to tie the triangles together.
We would use a rigid transformation to have angle NPO move to angle NLM, or vice versa through the use of a rotation and a translation.
Angle Angle AA similarity postulate states that two triangles are similar if
two angles in one of the triangles are congruent (equal) to two angles in the
other triangle
The correct option for the method and additional information that would
prove triangle ONP and triangle MNL similar by AA similarity postulate is
option B.
B. Use rigid transformation to prove that angle NPO is congruent to angle NLM
The reason for arriving at the above selection is as follows;
The known parameter in triangle ΔONP and ΔMNL are;
Lines MO and LP intersect at vertex point N.
The angles on opposite side of the point N (either side of the X shape
formed by the two lines) which are ∠ONP and ∠LNM are vertically opposite
angles or opposite angles.
According to vertically opposite angles theorem ∠ONP and ∠LNM, which
are vertically opposite angles are congruent, and we can write.
∠ONP ≅ ∠LNM
The required parameter;
To find the additional information that would prove ΔONP and ΔMNL by
AA (Angle-Angle) similarity postulate.
Strategy;
Given that from the drawing, one (vertex) angle in one triangle is congruent
to one (vertex) angle in the other triangle, that is ∠ONP ≅ ∠LNM, it is
required to prove that one other angle in triangle ΔONP is congruent to a
corresponding angle in triangle ΔMNL.
Solution;
Prove that either ∠NPO or ∠NOP in ΔONP are congruent to ∠NLM or
∠NML respectively in ΔMNL by performing rigid transformations
(transformations that does not change shape) on either ΔONP or ΔMNL
including;
Rotating triangle ΔONP by 180° with origin at point N, to form the image ΔO'N'P'.Translating the vertex point P' in the image ΔO'N'P', to the location of the point L in ΔMNL, and verify that the segments LN and LM in ΔMNL coincide with the segments P'N' and P'O' respectively of triangle ΔO'N'P'.Therefore, the correct option is option B. Use rigid transformation to prove
that angle NPO is congruent to angle NLM.

THEIR AGES
If you add the square of Tom's age to the age of Mary the sum is 62; but if you
add the square of Mary's age to age of Tom, the result is 176. Can you say
what are the ages of Tom and Mary?
Answer:
Tom’s age is 7 years
Mary’s age is 13 years
Step-by-step explanation:
Since we do not know the ages, let’s represent the ages by variables at first.
Let m represent mary’s age will t represent Tom’s age.
Now, let’s proceed to have equations.
Adding square of Tom’s age (t^2) to mary’s age give 62
t^2 + m = 62 •••••••(i)
Adding square of mary’s age (m^2) to Tom’s age give 176
m^2 + t = 176 •••••••(ii)
Now, to get the individual ages, we will need to solve both equations simultaneously.
Solving both equations simultaneously without mathematical softwares can be a little hard.
By the use of mathematical software ( wolfram alpha to be specific), we can input both equations and allow the software to solve.
By inputing these equations, we have the values of t to be 7 and m to be 13
And if we try to check by inspection, we can see that these values are actually correct.
7^2 + 13 = 62
13^2 + 7 = 176

Find the value of c and a.
Answer:
c = 93.5° , a = 52°Step-by-step explanation:
x = 52°
b = ¹/₂(2x) = x = 52°
y = 180° - 90° - x
y = 90° - 52° = 38°
a = 180° - 90° - y = 90° - 38° = 52°
p = 83°
q = ¹/₂p = 41.5°
(180° - c) + b + q = 180°
180° - c + 52° + 41.5° = 180°
- c = - 93.5°
c = 93.5°

Answer:
Postulate 5, The Parallel postulate: If a straight line intersects two other straight lines, and so makes the two interior angles on one side of it together less than two right angles, then the other straight lines will meet at a point if extended far enough on the side on which the angles are less than two right angles.
The parallel postulate is needed to derive the elements, but it seems too complex.

when x = -3?
Answer:
f(-3) = -20
Step-by-step explanation:
We observe that the given x-values are 3 units apart, and that the x-value we're concerned with is also 3 units from the first of those given. So, a simple way to work this is to consider the sequence for x = 6, 3, 0, -3. The corresponding sequence of f(x) values is ...
34, 10, -8, ?
The first differences of these numbers are ...
10 -34 = -24
-8 -10 = -18
And the second difference is ...
-18 -(-24) = 6
For a quadratic function, second differences are constant. This means the next first-difference will be ...
? -(-8) = -18 +6
? = -12 -8 = -20
The value of the function at x=-3 is -20.

-5 + x = 2 1/2
How do I solve this problem
Answer:
x = 15/2
Step-by-step explanation:
Solve for x:
x - 5 = 2 + 1/2
Hint: | Put the fractions in 2 + 1/2 over a common denominator.
Put 2 + 1/2 over the common denominator 2. 2 + 1/2 = (2×2)/2 + 1/2:
x - 5 = (2×2)/2 + 1/2
Hint: | Multiply 2 and 2 together.
2×2 = 4:
x - 5 = 4/2 + 1/2
Hint: | Add the fractions over a common denominator to a single fraction.
4/2 + 1/2 = (4 + 1)/2:
x - 5 = (4 + 1)/2
Hint: | Evaluate 4 + 1.
4 + 1 = 5:
x - 5 = 5/2
Hint: | Isolate terms with x to the left hand side.
Add 5 to both sides:
x + (5 - 5) = 5/2 + 5
Hint: | Look for the difference of two identical terms.
5 - 5 = 0:
x = 5/2 + 5
Hint: | Put the fractions in 5/2 + 5 over a common denominator.
Put 5/2 + 5 over the common denominator 2. 5/2 + 5 = 5/2 + (2×5)/2:
x = 5/2 + (2×5)/2
Hint: | Multiply 2 and 5 together.
2×5 = 10:
x = 5/2 + 10/2
Hint: | Add the fractions over a common denominator to a single fraction.
5/2 + 10/2 = (5 + 10)/2:
x = (5 + 10)/2
Hint: | Evaluate 5 + 10.
5 + 10 = 15:
Answer: x = 15/2
Answer:
7 1/2
Step-by-step explanation:
Hello!
To solve this we have to get x by itself
What we do to one side of the equation we have to do to the other
-5 + x = 2 1/2
To get -5 to the other side we have to add 5 to make it zero
What we do to the left side we have to do to the right
-5 + 5 + x = 2 1/2 + 5
Simplify
0 + x = 7 1/2
We can drop the 0
x = 7 1/2
The answer is 7 1/2

An ordinary (fair) die is a cube with the numbers through on the sides (represented by painted spots). Imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment. Compute the probability of each of the following events.
Event A: The sum is greater than 7.
Event B: The sum is divisible by 4 or 6 (or both).
Answer:
a. 5/12
b. 7/18
Step-by-step explanation:
In this question, we are interested in computing the probabilities.
Firstly, we need to get the sample space of the results. This refer to all possible results that can emerge from the rolling of the two die.
This can be found in the attachment.
What is important to know however is that the total number of possible results is 36;
so let’s compute;
a. For a, let’s circle all sums which are greater than 7 ;
We can see a total of 16 circled sums;
So the probability is 15/36 = 5/12
b. Sum divisible by 4 or 6 or both
Let’s make a circle again ;
So we have a total of 14
So the probability will be 14/36 = 7/18

Forty-seven percent is the parameter and 31% is the statistic
Forty-seven percent is the statistic and 31% is the parameter
Answer:
47% is the statistic and 31% is the parameter.
Step-by-step explanation:
A parameter is a quantity of a variable representing certain characteristic of a population.
A statistic is a quantity of a variable representing certain characteristic of a sample.
The sample of parents of kindergartners selected is, n = 345.
The School records show that only 31% of parents of kindergartners sent their children to pre-kindergarten.
That is the population proportion is, p = 0.31.
This is the parameter value.
Of the 349 parents, 47% said they sent their children to pre-kindergarten.
That is the sample proportion is, [tex]\hat p[/tex] = 0.47.
This is the statistic value.
Thus, the correct option is:
47% is the statistic and 31% is the parameter.
