Answer: 120 minutes which equals 2 hours
Emma works two jobs. At her day job, she earns $8/hour and works for 3 hours. She works her evening job for 9 hours and earns $14.50/hour. How much does she make on average per hour for the day? Explain the process of finding Emma's average wage per hour.
Answer: $12.875
Step-by-step explanation:
Emma works two jobs. At her day job, she earns $8/hour and works for 3 hours. Total amount earned will be:
= $8 × 3 = $24
She works her evening job for 9 hours and earns $14.50/hour. Total amount earned will be:
= $14.50 × 9 = $130.5
Total amount earned will now be:
= $24 + $130.5
= $154.5
Since she works a total of: 3 hours + 9 hours = 12 hours per day, the amount made on average per hour will be:
= $154.5/12
= $12.875
Solve the inequality.

Line L has the equation y = -2x - 3.
Line M is perpendicular to Line L and intersects the y-axis at (0,9)
Write Down the equation of Line M in the form y=mx+c
Answer:
[tex]y=\dfrac12x+9[/tex]
Step-by-step explanation:
The product of the slopes of perpendicular lines is -1
Given the slope of Line L is -2, this means that the slope of Line M will be:
[tex]\dfrac{-1}{-2}=\dfrac12[/tex]
[tex]\sf as \ \dfrac12 \cdot -2 = -1[/tex]
If Line M intersects the y-axis at (0, 9) then its y-intercept is 9.
Slope-intercept of a linear equation: [tex]y = mx + c[/tex]
(where m is the slope and c is the y-intercept)
Therefore, the equation for Line M is:
[tex]y=\dfrac12x+9[/tex]

HELP 100 POINTS What is the measure of ∠A in the image below?
Answer:
A. m∠A = 45°
Step-by-step explanation:
Vertical angle theorem: opposite angles are congruent
⇒ 3x = x + 30
⇒ 2x = 30
⇒ x = 15
As m∠A = 3x
⇒ m∠A = 3 × 15 = 45°
Opposite angles are equal
[tex]\\ \rm{:}\dashrightarrow 3x=x+30[/tex]
[tex]\\ \rm{:}\dashrightarrow 2x=30[/tex]
[tex]\\ \rm{:}\dashrightarrow x=15[/tex]
So
<A=3(15)=45A two digits number is seven times the sum of its digits . The number formed by reversing the digits is 18 less than the original number. Find the number .
Hey there!
10x+y=7(x+y)=7x+7y
or 10x−7x=7y−y
or 3x=6y
or x=2y ........(1)
Number formed by reversing the digits is yx, i.e.,
10y+x=10x+y−18
Substituting x=2y, we get
10y+2y=10×2y+y18
or 2y=21y−18
or 21y−12y=18
or 9y=18
or y=2
∴x=2y=2×2=4
Therefore, the number is 42.

Let the two digit number be ' xy '
where, x is the ten's place digit, and y is one's place digit, now let's proceed further ~
The origin number can be written as :
[tex]\qquad \sf \dashrightarrow \: 10x + y[/tex]
[ because x is at ten's place ]
of the digits are swapped, the new number will be :
[tex]\qquad \sf \dashrightarrow \: 10y + x[/tex]
According to conditions provided in the question : -
[tex]\qquad \sf \dashrightarrow \: 10x + y = 7 \times (x + y)[/tex]
[tex]\qquad \sf \dashrightarrow \: 10x + y = 7x + 7y[/tex]
[tex]\qquad \sf \dashrightarrow \: 10x - 7x + y - 7y= 0[/tex]
[tex]\qquad \sf \dashrightarrow \: 3x - 6y = 0 \: \: \: \: \: \: [/tex]
[tex]\qquad \sf \dashrightarrow \: x - 2y = 0 \: \: \: \: \: \: - (1)[/tex]
here we got our first equation, let's find the other one ~
[tex]\qquad \sf \dashrightarrow \: (10x + y) - 18= 10y + x[/tex]
[tex]\qquad \sf \dashrightarrow \: 10x - x + y - 10y = 18[/tex]
[tex]\qquad \sf \dashrightarrow \: 9x - 9y = 18[/tex]
[tex]\qquad \sf \dashrightarrow \: x - y = 2 \: \: \: \: \: \: - (2)[/tex]
we got our second equation ~
Now it's time to subtract equation (1) from equation (2) :
[tex]\qquad \sf \dashrightarrow \:( x - y ) - (x - 2y)= 2 - 0[/tex]
[tex]\qquad \sf \dashrightarrow \: \cancel{x }- y - \cancel{x} + 2y= 2 - 0[/tex]
[tex]\qquad \sf \dashrightarrow \: y= 2 [/tex]
hence, value of y is 2, use this value in equation (2) to find x ~
[tex]\qquad \sf \dashrightarrow \: x - y= 2 [/tex]
[tex]\qquad \sf \dashrightarrow \: x - 2= 2 [/tex]
[tex]\qquad \sf \dashrightarrow \: x = 4 [/tex]
Therefore, the required number is xy = 42

2 to the power minus 6 as a fraction
Answer:
1/64
Step-by-step explanation:
A negative exponent in essence brings your 2^6 value under 1. So your problem would now look like 1/(2^6). From there it is easy simplifying, knowing hat 2^6 = 64. So your answer turns out to be 1/64.
2 to the power minus 6 as a fraction would be equal to 1/64

Answer:
l = √10
Step-by-step explanation:
We're given the value of a as 3 feet and the value of b as 1 feet (because 2/2 = 1). We are to find the value of l using Pythagorean Theorem.
[tex]3^2+1^1=l^2[/tex] [tex]9+1=l^2[/tex] [tex]10=l^2[/tex] [tex]l=\sqrt{10}[/tex]Therefore, the answer is √10 feet.
When a LINE SEGMENT is reflected over a line of symmetry, what is changing?
A. The LENGTH of the line segment
B. The DISTANCE of the line segment from the line of symmetry
C. The coordinates of the ENDPOINTS of the segment
Answer:
The correct answer would be C. The coordinates of the ENDPOINTS of the segment
Step-by-step explanation:
It cannot be A, because the segment only moves. It does not change size.
It cannot be B, because the line of symmetry goes down the middle of the segment- the distance remains the same.
Therefore it is C. The coordinates of the ENDPOINTS of the segment

Mark Bought a concert ticket for $88 then sold it for $121. By what percent did the price go up.
Answer:
33.5%
Step-by-step explanation:
First you need to subtract the amount he bought the ticket from the amount he sold it.
$121 ₋ $88
=$33
After that you need to divide the answer you got by the original amount of the ticket multiply it by 100.
33 ÷ 88 × 100
=37.5%

Answer:
vertical angles - angle 2 and 4, angle 1 and 3
adjacent angles- angle 2 and 3, angle 1 and 4
2x + y = 2
-3x + y = 4
Transfer these into y=mx+b
Step-by-step explanation:
2x + y = 2 subtract 2x from both sides
2x - 2x + y = 2 - 2x
y = -2x + 2
(m = -2, b = 2)
-3x + y = 4 add 3x to both sides
-3x + 3x + y = 4 + 3x
y = 3x + 4
(m = 3, b = 4)
Triangle TRW is shown on the coordinate grid. x, y, t, r, w Triangle TRW will be dilated by a scale factor of n with the origin as the center of dilation to create triangle T′R′W′. Which ordered pair best represents the location of point R′?
Dilating the triangle TRW would change the size of the triangle
The ordered pair that best represents the location of point R′ is (nRx,nRy)
How to determine the ordered pair?The coordinates of the point R would be represented as:
R = (Rx,Ry)
The scale of dilation (k) is given as:
k = n
Given that the center of dilation is the origin, the location of point R' would be:
R' =R * k
So, we have:
R' = (Rx,Ry) * n
Evaluate the product
R' = (nRx,nRy)
Hence, the ordered pair that best represents the location of point R′ is (nRx,nRy)

A una persona le ofrecieron dos trabajos de vendedor. En la empresa A, le ofrecieron al mes un sueldo base de $6 000 más una comisión de $20 por cada pieza vendida. En la empresa B, le ofrecieron el mismo sueldo base más una comisión igual al cuadrado de la cantidad de piezas vendidas. ¿A partir de qué cantidad de piezas vendidas en un mes le pagan más en la empresa B que en la A?A.
15
B.
19
C.
20
D.
21
Concluimos que a partir de 21 piezas se gana más en la empresa B.
¿Cuanto debe vender para que le paguen más en la empresa B?
Si definimos el número de piezas vendidas como x, la cantidad que le pagan en la empresa A es:
A(x) = $6000 + $20*x
Y lo que le pagan en la empresa B es:
B(x) = $6000 + x^2
Queremos ver para que valor de x, se da que B(x) > A(x).
Entoces resolvamos esa inequación.
6000 + 20*x < 6000 + x^2
20x < x^2
20 < x
x debe ser más grande que 20, entonces concluimos que a partir de 21 piezas se gana más en la empresa B.

A 12,000 seat arena is divided into 60 equal sections of 200 seats. In order to
estimate the attendance at an event, management takes a sample from one of these
sections. At a recent event, 174 people were counted in this sample section. What
was the estimated attendance at this recent event?
Answer:
10,440
Step-by-step explanation:
There is 12k seats in total. 60 sections containing 200 seats. In 1 section of 200 they counted 174 people. Therefore you multiply 174 by 60. 174 being the people in 1 section and 60 being the total number of sections.

Factor the following quadratic:
[tex]3x^2+7x-6[/tex]
Step-by-step explanation:
Use the systematic new AC Method to factor trinomials (Socratic Search)
y
=3x2+7x−6
=3(x + p)(x + q)
Converted trinomial:
y'
=x^2+7x−18
= (x + p')(x + q').
p' and q' have opposite signs.
Factor pairs of (ac = -18) --> (-2, 9). This sum is 7 = b. Then p' = -2 and q' = 9. Therefore,
p ='p/a
= -2/3
and
q ='q/a
=9/3
=3.
Factored form: y = 3(x - 2/3)(x + 3) = (3x - 2)(x + 3)
