Answer:
Total profits = 49.50n
Step-by-step explanation:
Cost of each quilt = $30.50
Selling price of each quilt = $80
Profits = selling price - cost price
= $80 - $30.50
= $49.50
Profits = $49.50
If n = number of quilts she sells
which expression could be used to represent her total profits?
Total profits = profits of each quilt × number of quilt sold
= $49.50 × n
= 49.50n
Total profits = 49.50n

Answer:
Infinite amount of solutions
Step-by-step explanation:
This is because 3(x+5) = 3x+15
so then it would be 3x+15=3x+15
Any number in the X place would make this statement true
Answer: Infinitely Many solutions
Step-by-step explanation:
you distribute the 3 to ‘x’ and ‘15’ getting 3x + 15 on the right side. All together the equation is:
3x + 15 = 3x + 15
so no matter what number you decided to add, it’ll be the same answer, therefore making it infinitely solutions.
Akira is folding a piece of paper that is 0.2 millimeters thick in half. The thickness of the paper doubles with each fold.
Let n represent the fold number and t (n) represent the thickness of the paper.
Which exponential function represents this scenario?
A t(n) = 1/2 (0.2)"
B
t(n) = 0.2(2)”
с
t(n) = 0.2()"
D
t(n) = 2(0.2)”
( the " are n)
Answer:
B. t(n) = 0.2(2)ⁿStep-by-step explanation:
Initial value is 0.2 and increase rate is powers of 2 as it doubles with each fold.
Correct one is:
t(n) = 0.2(2)ⁿA car travels for x hours at a speed of (x + 2) km/h. If the distance
travelled is 15 km, write down an equation for x and solve it to find
the speed of the car.
Step-by-step explanation:
S = v/t
(x+2)km/h
((x+2)×1000)/(60×60) = (15×1000)/(60×60)
(5(x+2)/18) = 25/6
30(x+2) = 18×25
x+2 = 15
x = 13m/s
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
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.
Hope that helps :)
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?
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
A cafe is open for six days a week. There was a mean number of 86 customers for five days. On the next day there were 122 customers. What is the mean number of customers over the six days?
Answer:
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

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.
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.

Answer:
E1488
Step-by-step explanation:
Since its E1200,
we find the total.
Total= time times money times interest.
1200*0.08 ( thats 8%) *3.
So, we multiply 1200*0.08*3.
the answer is 288.
1200+288 is 1488.

what is the slope of a line that passes through (-1,4) and (4,9)
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.

7/12 divided by 5/9 in its simplest form
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.
