find the value of x?!??????
Answer:
x = 31
Step-by-step explanation:
Given:
MN = 20
PQ = x
RS = 42
Required:
Value of x
SOLUTION:
In a trapezoid, the midsegment length equals the sum of both bases divided by 2
This implies that:
PQ = ½(MN + RS)
Plug in the values
x = ½(20 + 42)
x = ½(62)
x = 31
Tommy buys a new stereo that sells for $1052.75 plus taxes. At the time of the
purchase the taxes and a $40 deferral charge are paid. The selling price is paid in
12 monthly payments.
A) What is the total amount to be paid at the time of the purchase?
B) What is the amount of each monthly payment?
Answer: See explanation
Step-by-step explanation:
A. What is the total amount to be paid at the time of the purchase?
This will be the selling price of the stereo with the tax and the deferral. This will be:
= $1052.75 + $40
= $1092.75
B) What is the amount of each monthly payment?
Each monthly payment will be gotten by dividing the total payment to be made by 12. This will be:
= $1092.75 / 12
= $91.06
Perimeter is always measured in square units.
True
False
false
Step-by-step explanation:
the perimeter is all the sides added up whereas the area is length × width

The perimeter does not measures in square units because area should be measured.
What is the perimeter?A perimeter refers to the closed path that encompasses or outlines and represents the two-dimensional shape or a one-dimensional length. The perimeter of a circle is known its circumference.

Step-by-step explanation:
Surface area of rectangular prism
= 2lw + 2lh + 2wh
= 2(10)(4) + 2(10)(5) + 2(4)(5)
= 80 + 100 + 40 = 220 square inches.
Volume of rectangular prism

How do you work out the size of angle x ?
Answer:
117°
Step-by-step explanation:
Angle of straight line is 180°
Angles in a triangle add up to 180°
starting at right
180 - 101 = 79° at right side angle in triangle
now solving left side angle
180 - 38 - 79 = 63°
now solving x using left side angle, must add to 180°
x + 63 = 180°
x = 117°
x is an exterior angle of the triangle and its measure is 117 degrees.
Given,
Triangle with interior and exterior angles.
Linear pair : ∠x + ∠y = 180 degrees.
Angle of straight line is 180°(Linear pair).
180 - 101 = 79°
Angle sum property: Sum of all the angles in a triangle add up to 180° .
So,
180 - 38 - 79 = 63°
Now solving x,
Angles must add to 180° in a straight line.
x + 63 = 180°
x = 117°
Therefore measure of angle x in the triangle is 117 degrees.

Students obtained a mean score of 400 and standard deviation of 40 in a test with a bell-shaped distribution. What approximate percentage of the students above 520
The percentage of students who scored above 520 is 0.13%.
Given data:
To determine the approximate percentage of students who scored above 520, use the concept of standard deviations.
Given that the mean score is 400 and the standard deviation is 40, calculate the z-score for the value of 520 using the formula:
z = (x - mean) / standard deviation
where x is the value of interest.
So, x = 520, mean = 400, and standard deviation = 40. Plugging in these values:
z = (520 - 400) / 40
z = 120 / 40
z = 3
The z-score of 3 represents a value that is 3 standard deviations above the mean.
To find the approximate percentage of students above 520, we can refer to the standard normal distribution table (also known as the Z-table). Looking up the z-score of 3 in the table, the area to the left of this z-score is approximately 0.9987.
To find the percentage above 520, subtract this value from 1 to find the area to the right of the z-score:
1 - 0.9987 = 0.0013
Hence, approximately 0.13% of students scored above 520 in the test.

A store is instructed by corporate headquarters to
put a markup of 25% on all items. An item costing $16 is displayed by the store manager at a selling price of $4. As an employee, you notice that this selling price is incorrect. Find the correct selling price. What was the manager's likely error?
Can someone help? It would be appreciated! ♡︎
Answer:
Find out the selling price.
To prove
As given
A store manager instructs his employees to mark up all the items by 25%. An item that the store bought for $16.
25% is written in the decimal form.
= 0.25
25% of the $16= 0.25 × 16
= $4
Selling price of the item = Original price of item + 25% of the $16
= $16 + $4
= $ 20
Therefore the selling price of the item is $20.

Which ordered pair, when graphed, would not show a function?
(miles per gallon, gallons in tank)
(length of shadows/time of day)
(temperature in F, temperature in C)
(number of employees, number of hours worked)
Answer:
a) miles per gallon, gallons in tankStep-by-step explanation:
All the options show functional relationship but the first one
a) miles per gallon, gallons in tank
There is no direct relationship between these parameters as miles per gallon depends on the speed and the way of driving. This won't be a function when graphed.b) length of shadows/time of day
Shadow depends on the time of the day and its length wont repeat at different angles. This is a function.c) temperature in F, temperature in C
This is a function as each input will have a unique output.d) number of employees, number of hours worked
Hours of work depends on number of employees. This is a functional relationship.Answer:

-4 = r/20 -5
Solve for r. Show your steps
Answer:
r = 20
Explanation:
-4 = r/20 - 5
Simplify both sides of the equation-4 = r/20 - 5
-4 = 1/20r + -5
-4 = 1/20r - 5
Flip the equation1/20r - 5 = -4
Add 5 to both sides1/20r - 5 + 5 = -4 + 5
1/20r = 1
Multiply both sides of the equation by 20(20)1/20r = 1(20)
r = 20Margie says the set of numbers, 0.1, -1, -21

Answer:
Simplified answer is: [tex]8a^2 - ab + 2b + 9[/tex]
Step-by-step explanation:
Key skills needed for understanding: Combining Like Terms
1) You are given the equation: [tex](3a^{2} + 2ab + 2b) + (5a^{2} - 3ab + 9)[/tex]
- Since you are adding here, you can remove the parentheses.
- If you remove them it would be --> [tex]3a^2 + 2ab + 2b + 5a^2 - 3ab + 9[/tex]
2) Now we have to combine like terms in order to simplify this equation.
Combining like terms is simply combining terms with the same base (such as the terms that have "ab" or the terms that have "[tex]a^2[/tex]" or the terms that have nothing - these terms are numbers such as 9 or 5).
You can combine 2ab and -3ab, but you cannot combine 9 and 2b. Hope you understood this concept.
3) If you combine like terms ( [tex]3a^2 + 5a^2[/tex], [tex]2ab - 3ab[/tex]) you will get a different expression: [tex]8a^2 - ab + 2b + 9[/tex].
[tex]8a^2 - ab + 2b + 9[/tex] is the answer.

Bag A contains 3 red balls and 3 blue balls.
Bag B contains 1 red ball and 3 blue balls.
A ball is taken at random from bag A and placed in bag
B. A ball is then chosen from bag B. What is the probability
that the ball taken from B is red?
Answer:
30% probability that the ball taken from B is red.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Red ball from urn A:
3/6 = 1/2 probability of getting a red ball from urn A.
Then urn B will have 5 balls, 2 of which are red, so 2/5 probability of getting a red ball.
Blue ball from urn A:
3/6 = 1/2 probability of getting a blue ball from urn A.
Then urn B will have 5 balls, 1 of which is red, so 1/5 probability of getting a red ball.
Total:
[tex]p = \frac{1}{2}*\frac{2}{5} + \frac{1}{2}*\frac{1}{5} = \frac{2}{10} + \frac{1}{10} = \frac{3}{10}[/tex]
3/10 = 0.3 = 30%.
30% probability that the ball taken from B is red.
Find a vector 3 units long in the opposite direction from v = 〈3, 1,-4).
Unit vector along the direction v = <3,1,-4> is :
[tex]\hat{v} = \dfrac{3i + j -4k}{\sqrt{3^2 + 1^2 + 4^2}}\\\\\hat{v} = \dfrac{3i + j -4k}{5.1}[/tex]
So, unit vector opposing the [tex]\hat{v}[/tex] is :
[tex]\hat{v'} = -\hat{v}\\\\\hat{v'} = -( \dfrac{3i + j -4k}{5.1})\\\\\hat{v'} = \dfrac{-3i - j +4k}{5.1}[/tex]
so, vector of magnitude 3 units in opposite direction from v is :
[tex]\vec{V} = 3\hat{v'}\\\\\vec{V} = \dfrac{3}{5.1}( -3i -j+4k)[/tex]
Hence, this is the required solution.
