Gavin drank 4.5 liter of water Monday before going jogging. He drank 2.3 liter of water after his jog. How much water did Gavin drink altogether? Write your answer as a mixed number.
Given
we are told that he first drank 4.5 liters of water before jogging
after jogging he drank 2.3 liters
Required
Total amount of water drank
=4.5+3.5
=8.0liters
The price for chips have increased by 12% in recent years.If the approximate price for chips today is 2.50, how much was original price before the increase?
Answer:
Approximately $2.232
Step-by-step explanation:
Given that:
Percentage increase in Price of chips = 12%
Approximate price of chips today = $2.50
Original price before the increase :
Let original price = y
(Original price) + (12% of original price) = approximate price today
y + (12% of y) = $2.50
y + 0.12y = 2.50
1.12y = 2.50
Divide both sides by 1.12
1.12y / 1.12 = 2.50 / 1.12
y = 2.2321428
y = $2.232
Hence, original price of chips is approximately $2.232
Find the slope of the line. Use the "/" to make a fraction
Answer:
-1/6
Step-by-step explanation:
The slope is negative because it's going left. If you count the spaces between the points, they go back 6 and up 1, making it -1/6
Enunciado:Si una empresa determina que sus costos obedecen a un modelo lineal y además sabe que si produce $10$ unidades sus costos totales son de $4000$ dólares y que si produce $15$ unidades sus costos ascienden a $5000$ dólares, entonces la función que modela sus costos totales es:
Responder:
y = 200x + 2000
Explicación paso a paso:
Deje que la ecuación lineal se exprese como y = mx + c
m es la pendiente
c es la intersección
Si la empresa produce $ 10 unidades, sus costos totales son $ 4000 dólares y si produce $ 15 unidades sus costos ascienden a $ 5000 dólares, entonces podemos representar esto como puntos de coordenadas;
(10,4000) y (15,5000)
Conseguir la pendiente
m = 5000-4000 / 15-10
m = 1000/5
m = 200
Obtener la intersección c
Sustituya m = 2000 y el punto (10, 4000) en la fórmula y = MX + c
4000 = 200 (10) + c
4000-2000 = c
c = 2000
Sustituya m = 200 y c = 2000 en la ecuación y = mx + c
y = 200x + 2000
Por tanto, la expresión lineal requerida es y = 200x + 2000

Juan and Dylan are selling bottled water. Juan sold 4 bottles for every 6 that Dylan sold. Dylan sold 16 more bottles than Juan. How many did each boy sell?
Answer:
Dylan sold 48 bottles
Juan sold 32 bottles
Step-by-step explanation:
The ratio of bottles sold is;
J:D = 4:6
Dylan sold 16 more than Juan
That means d = j + 16
so;
j/j + 16 = 4/6
6j = 4(j + 16)
6j = 4j + 64
6j - 4j = 64
2j = 64
j = 64/2
j = 32
d = j + 16
d = 32 + 16
d = 48

All angles in a triangle add up to 180°Step-by-step explanation:
Step 1: Set up equation
8x + 2 + 70 + 60 = 180
Step 2: Solve for x
Combine like terms: 8x + 132 = 180Subtract 132 on both sides: 8x = 48Divide 8 on both sides: x = 6And we have our final answer!
Factor 6c - 8d
help please!
Answer:
6c - 8d = 2 (3c - 4d)
Step-by-step explanation:
Factoring
To factor a polynomial, we must find the Greatest Common Divisor (GCD) among all its terms.
The expression to factor is 6c - 8d.
The GCD is found by factoring all terms:
6c : 2,3,c
8d : 2,2,2,d
And take the common divisor between the coefficients and the variables
GCD=2
Thus, the factorization is:
6c - 8d = 2 (3c - 4d)

What equation is graphed in this figure?
A. y−4=−13(x+2)
B. y−3=13(x+1)
C. y+2=−3(x−1)
D. y−5=3(x−1)
Answer:
c. [tex] y + 2 = -3(x - 1) [/tex]
Step-by-step explanation:
By using a point on the line and the slope, we can determine the equation, in point-slope form, that is graphed in the figure.
Using two points, (1, -2) and (0, 1),
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 -(-2)}{0 - 1} = \frac{3}{-1} = -3 [/tex]
m = -3
Using a point, (1, -2) and the slope (m), we can create an equation for the graph in point-slope form, by substituting x1 = 1, y1 = -2 and m = -3 in [tex] y - y_1 = m(x - x_1) [/tex].
Thus, we would have:
[tex] y -(-2) = -3(x - 1) [/tex]
[tex] y + 2 = -3(x - 1) [/tex]
The equation that is graphed in the figure is:
✔️[tex] y + 2 = -3(x - 1) [/tex]

The number of workers, f(x), needed to complete a building is given by the function below where x represents the number of floors in the building.
Select the correct statement.
When f(3) = 18, the 3 represents the the number of workers needed and the 18 represents number of floors.
When f(3) = 18, the 3 represents the number of floors and the 18 represents the number of workers needed.
When f(4) = 48, the 4 represents the number of floors and the 48 represents the number of workers needed.
When f(4) = 48, the 4 represents the the number of workers needed and the 48 represents number of floors.
Answer:
When f(4) = 48, the 4 represents the number of floors and the 48 represents the number of workers needed.

Last year during the hurricane season the amount of rain that fell on the texas gulf coast in october was 14 inches which was 3 1/2 times more than the rainfall during the month of september ?
Given :
Last year during the hurricane season the amount of rain that fell on the Texas gulf coast in October was 14 inches which was 3 1/2 times more than the rainfall during the month of September.
To Find :
Amount of rainfall in September.
Solution :
Let, amount of rainfall in September is x.
It is given that rainfall in October is 3 1/2 = 7/2 times of september.
So,
[tex]\dfrac{7}{2}x=14\\\\x = 4\ inches[/tex]
Therefore, rainfall in October is 4 inches.
Hence, this is the required solution.

graph the function. label the vertex and axis of symmetry
f(x) = -6x^2 - 4x - 5
Answer:
Vertex is (-1/3, -13/3)
Axis of symmetry is x = -1/3
Step-by-step explanation:
For the vertex, you need to change it into vertex form which is y = a(x - h)^2 + k
Vertex form for this equation is:
Y = -6(x + 1/3)^3 - 13/3
To find the vertex, the formula is (h,k)
So, ( -1/3, -13/3)
