Answer: $178.50
Step-by-step explanation:
If Alex is paid a piecework rate of $8.50 per motor, then;
Price per motor assembly = $8.50
By assembling 21 motors Alex gets,
1 motor = $8.50
21 motors = (21 * $8.50) / 1
= $178.50 / 1
= $178.50
By assembling 21 motors,
Alex gets $178.50
You reverse the inequality symbol when you multiply or divide both sides of an inequality by the same negative number true or false
Answer is in the file below
tinyurl.com/wpazsebu
Answer:
When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side! This is why you must flip the sign whenever you multiply by a negative number.

The interquartile range (IQR) of the data set is 24 degrees Celsius.
What is the interquartile range?The interquartile range (IQR) is a measure of variability or spread in a dataset. It is the difference between the third quartile (Q'') and the first quartile (Q) of the dataset.
To calculate the interquartile range (IQR) of this data set, we first need to find the first quartile (Q) and the third quartile (Q'').
Arrange the data in order from smallest to largest:
08, 09, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48
Find the median (Q') of the entire data set:
Median (Q') = (24 + 28)/2 = 26
Find Q by taking the median of the lower half of the data:
Lower half: 08, 09, 12, 16, 20, 24
Q = (12 + 16)/2 = 14
Find Q'' by taking the median of the upper half of the data:
Upper half: 28, 32, 36, 40, 44, 48
Q'' = (36 + 40)/2 = 38
Calculate the IQR by subtracting Q from Q'':
IQR = Q'' - Q = 38 - 14 = 24
Therefore, the interquartile range (IQR) of this data set is 24 degrees Celsius.

solve the simultaneous equation plz x
Answer:
x=4,y=3
Step-by-step explanation:
x=19-5y if we transpose equation 2 for x.
Plug that into equation 1
4(19-5y)+3y=25
76-20y+3y=25
76-25=17y
51=17y
y=3
Plug y=3 into equation 2
x+5(3)=19
x=19-15=4
We are having two equations,
4x + 3y = 25 (Equation No 1)x + 5y = 19 (Equation No 2)★ From Equation No 2 :-
>> x + 5y = 19
>> x = 19 - 5y
★ From Equation No 1 :-
Substitute here the value of x which we got above as (19 - 5y).
>> 4x + 3y = 25
>> 4 (19 - 5y) + 3y = 25
>> 4 × (19 - 5y) + 3y = 25
>> 76 - 20y + 3y = 25
>> 76 - 17y = 25
>> -17y = 25 - 76
>> -17y = -51
>> 17y = 51
>> y = 51 / 17
>> y = 3
★ Finding out value of x :-
>> x = 19 - 5y
>> x = 19 - 5(3)
>> x = 19 - 5 × (3)
>> x = 19 - 15
>> x = 4
what is meant by algebraic equation
Answer:
An algebraic equation is an equation used in algebra which uses numbers and letters. The letters are representing unknown numbers and are called variables.
Answer:
An algebraic equation is "a mathematical statement in which two expressions are set equal to each toher."
If that is too complicated to understand, look at it like this. An algebraic equation usually has two things: an equal sign, and letters. For example, this is an algebraic equation: x + 3 = 7.

Find the area of the kite
Given:
A figure of a kite.
To find:
The area of the given kite.
Solution:
The area of a kite is the half of the product of its diagonals.
[tex]A=\dfrac{d_1d_2}{2}[/tex] ...(i)
Where, [tex]d_1,d_2[/tex] are two diagonals of the kite.
From the given figure it is clear that the length of one diagonal is the sum of 12 and 8.
[tex]d_1=12+8[/tex]
[tex]d_1=20[/tex]
Let the second diagonal be 2x. The first diagonals bisect the second diagonal. So, the length of one parts of the diagonal is x.
Diagonals of a kite are perpendicular to each other. Using Pythagoras theorem, we get
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
[tex]13^2=x^2+12^2[/tex]
[tex]169-144=x^2[/tex]
[tex]25=x^2[/tex]
[tex]5=x[/tex]
The length of second diagonal is:
[tex]d_2=2x[/tex]
[tex]d_2=2(5)[/tex]
[tex]d_2=10[/tex]
Substituting [tex]d_1=20,d_2=10[/tex] in (i), we get
[tex]A=\dfrac{20\times 10}{2}[/tex]
[tex]A=\dfrac{200}{2}[/tex]
[tex]A=100[/tex]
Therefore, the area of the kite is 100 square units.
(section 6.1) Find the length of the small arc formed by the intersection of the unit circle a circle centered at the origin with a radius of 1: x2 + y2 = 1 and the line 2 y=1/2
Answer:
The length of the arc is approximately 2.0944
Step-by-step explanation:
The given parameters are;
The equation of the circle = x² + y² = 1
The radius of the circle, r = 1
The equation of the line, y = 1/2
Therefore, we point where the line intersects with the circle are given as the points 'y = 1/2' as follows;
When y = 1/2, the equation of the circle becomes;
x² + (1/2)² = 1
x² = 1 - (1/2)² = 3/4
x = ±√3/2
The angle subtended by the arc, θ = 2 × arctan((√3/2)/(1/2)) = 120°
The circumference of the circle, C = 2·π·r
∴ C = 2 × π × 1 = 2·π
The length of the arc, l = (θ/360) × C
∴ l = (120/360) × 2·π = (2/3)·π
The length of the arc, l = (2/3)·π ≈ 2.0944
The length of the arc is approximately 2.09
The intersection of the unit circle a circleFrom the question, we have the following parameters
The equation of the circle = x² + y² = 1
The radius of the circle, r = 1
The equation of the line, y = 1/2
The line intersects with the circle are given as the points 'y = 1/2' as follows;
When y = 1/2, the equation of the circle becomes;
x² + (1/2)² = 1
x² = 1 - (1/2)² = 3/4
x = ±√3/2
Determine the subtended angle
The angle subtended by the arc is expressed as:
θ = 2 × arctan((√3/2)/(1/2))
θ = 120°
The circumference of the circle, C = 2·π·r
C = 2 × π × 1 = 2·π
The length of the arc, l = (θ/360) × C
l = (120/360) × 2·π = (2/3)·π
The length of the arc, l = (2/3)·π ≈ 2.09
The length of the arc is approximately 2.09

Maria's kite tail was 3 1/2 feet long. Max's kite tail was 2 1/4 feet long. How much shorts was max's kite tail in inches?
Answer: [tex]\frac{5}{4}\ ft[/tex]
Step-by-step explanation:
Given
Maria kite tail is [tex]3\ \frac{1}{2}\ ft[/tex] long
Max's kite tail is [tex]2\ \frac{1}{4}\ ft[/tex] long
Converting it to a fraction
Maria kite tail
[tex]\Rightarrow \dfrac{3\times2+1}{2}=\dfrac{7}{2}\ ft[/tex]
Max's kite tail

Answer:
We know that for every (3/4) cups of sugar, she uses (1/2) cups of flour.
Now let's find how much flour she needs to use for each case:
If she uses (1/8) cups of sugar, how much flour she uses?
First, we need to count how many times we have (3/4) cups of sugar in (1/8) cups of sugar, which is the quotient:
(1/8)/(3/4) = 4/(3*8) = 4/24 = 1/6
This means that we need to use (1/6) times (1/2) cups of flour.
this is:
(1/6)*(1/2) cups of flour = (1/12) cups of flour.
If she uses (4/3) cups of sugar, we need to count how many times we have (3/4) cups of flour in that amount, this is:
(4/3)/(3/4) = (4*4)/(3*3) = 16/9
Then we need to se (16/9) times (1/2) cups of flour, this is:
(16/9)*(1/2) cups of flour = (16/18) cups of flour = (8/9) cups of flour
If she uses (1/2) cups of sugar, we need to count how many times we have (3/4) cups of sugar in that amount, this is:
(1/2)/(3/4) = 4/(2*3) = 4/6
Then she needs to use (4/6) times (1/2) cups of flour
this is:
(4/6)*(1/2) cups of flour = 4/(6*2) cups of flour = (1/3) cups of flour.
If she uses (1/4) cups of sugar, we need to count how many times we have (3/4) cups of sugar in that amount, this is:
(1/4)/(3/4) = 4/(4*3) = 4/12
Then she needs to use (4/12) times (1/2) cups of flour
this is:
(4/12)*(1/2) cups of flour = 4/(12*2) cups of flour = (1/6) cups of flour.
If she uses (1/5) cups of sugar, we need to count how many times we have (3/4) cups of sugar in that amount, this is:
(1/5)/(3/4) = 4/(5*3) = 4/15
Then she needs to use (4/15) times (1/2) cups of flour
this is:
(4/15)*(1/2) cups of flour = 4/(15*2) cups of flour = (2/15) cups of flour.
