Answers
Answer:
x = 30
Step-by-step explanation:
65 + 55 = 120
angle B must equal 60
angle B is labeled as 2x
set up equation to solve for 'x': 2x = 60
x = 30
add up all angles to make sure you get 180 degrees

A music company offers lessons. They charge a registration fee $30 and the $40 per lesson. The equation y=40x+30 represents the total cost y of x lessons.
What is the y intercept and what does it represent in the context of the problem?
What is the slope and what does it represent in the context of the problem?
What is the total cost if 6 lessons where taken?
Answers
Answer:
The y-intercept is 30 and represents the registration fee
The slope is 40 and represents the cost per lesson
The total cost of 6 lessons is $270
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slope of the line ⇒ rate of changeb is the y-intercept ⇒ initial value∵ A music company charges a registration fee of $30 and $40 per lesson
∵ The equation y = 40x + 30 represents the total cost y of x lessons
→ By comparing it with the form of the linear equation above
∴ m = 40
∴ b = 30
∵ b represents the y-intercept
∴ The y-intercept is 30
∵ The y-intercept is the initial value (value y at x = 0)
∴ The y-intercept represents the registration fee
∵ m is the slope
∴ The slope is 40
∵ The slope represents the rate of change
∴ The slope represents the cost per lesson
∵ x represents the number of lessons
∵ The number of lessons is 6
∴ x = 6
→ Substitute x by 6 in the equation to find the total cost of 6 lessons
∵ y = 40(6) + 30
∴ y = 240 + 30
∴ y = 270
∵ y represents the total cost
∴ The total cost of 6 lessons is $270
what is the slope of a line that passes through (-1,4) and (4,9)
Answers
Answer:
1
Step-by-step explanation:
Use rise over run, (y2 - y1) / (x2 - x1)
Plug in the points:
(y2 - y1) / (x2 - x1)
(9 - 4) / (4 + 1)
5 / 5
= 1
So, the slope is 1.
The Candle Company is having its seminual sale. All items are 40 percent off. If the original price of a candle basket is $120, what is the sale price
Answers
Answer:
the sale price would be $48
Step-by-step explanation:
To get the sale price you would have to find the decimal form of 40 which is 0.40. Then you multiply 0.40 by 120. And that is 48.00. So than the $48.00 becomes the sale price.

7/12 divided by 5/9 in its simplest form
Answers
Answer: 1 and 1/20th. Don’t know if it’s in simplest form tho
Step-by-step explanation:
7/12 divided by 5/9, in its simplest form, is 21/20.
Given that we need to divide 7/12 by 5/9,
The reciprocal of a fraction is obtained by interchanging the numerator and the denominator.
So, to simplify 7/12 divided by 5/9, we multiply 7/12 by the reciprocal of 5/9:
7/12 ÷ 5/9 = 7/12 × 9/5
Next, we multiply the numerators and denominators:
(7 × 9) / (12 × 5) = 63/60
To simplify this fraction further, we can divide both the numerator and denominator by their greatest common divisor (GCD), which is 3:
63/60 = (63 ÷ 3) / (60 ÷ 3) = 21/20
Therefore, 7/12 divided by 5/9, in its simplest form, is 21/20.

Cual es el tiempo que debe transcurrir para que un préstamo de $ 160.000 genere un interés de $ 15.000 a una tasa del 5,5% de interés simple.
Answers
Answer:
2 años.
Step-by-step explanation:
De la pregunta anterior, se obtuvieron los siguientes datos:
Principal (P) = $ 160,000
Intereses (I) = $ 15,000
Tasa (R) = 5,5%
Tiempo (T) =?
Así, podemos obtener el tiempo que tarda el préstamo de $ 160.000 en generar un interés de $ 15.000 a una tasa de interés simple del 5,5% de la siguiente manera:
I = PRT / 100
15000 = 160000 × T × 5.5 / 100
15000 = 880000 × T / 100
15000 = 8800 × T
Dividir ambos lados por 8800
T = 15000/8800
T = 1,7
T ≈ 2 años
Por lo tanto, tomará aproximadamente 2 años.

92
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
The sum of customers over the 5 days is
[tex]\frac{sum}{5}[/tex] = 86 ( multiply both sides by 5 )
sum = 430
Thus mean over the 6 days is
mean = [tex]\frac{430+122}{6}[/tex] = [tex]\frac{552}{6}[/tex] = 92
