Owen and Jesse go to a restaurant for breakfast. A 7% sales tax is applied to their $21.60 bill. If Owen and Jesse add a 15% tip after the tax is applied, what is the total cost, including tip?
Answer:
The total cost is 26.6 dollars
Step-by-step explanation:
Given
The total bill of the breakfast = $ 21.60
Sales tax = 7% of the total bill value
Total bill after adding the 7% sales tax
$ 21.60 + 7% of $ 21.60
[tex]21.60 + \frac{7}{100} * 21.60\\21.60 + 1.512\\23.112[/tex]dollars
After adding 15% of the tip values to the payable amount of $ 23.112, the total bill becomes
$ 23.112 + 15% of $ 23.112
[tex]23.112 + 3.4668 = 26.5788[/tex]
The total cost is 26.6 dollars

Answer:
[tex]pH = 13[/tex] --- Oven Cleaner
[tex]pH = 6.2[/tex] --- Water
[tex]pH =7.4[/tex] --- Blood
[tex]pH = 2.2[/tex] --- Vinegar
Step-by-step explanation:
The given molar concentration are:[Missing from the question]
Oven Cleaner: [h+] = [tex]10^{-13}[/tex]
Water: [h+] = [tex]0.0000007[/tex]
Blood: [h+] = [tex]0.00000004[/tex]
Vinegar: [h+] = [tex]0.0063[/tex]
Required
Determine the pH
pH is calculated using:
[tex]pH = -\log(h+)[/tex]
So, we have:
Oven Cleaner:
[tex]pH = -\log(10^{-13})[/tex]
Using a calculator, we have:
[tex]pH = 13[/tex]
Water:
[tex]pH = -\log(0.0000007)[/tex]
Using a calculator, we have:
[tex]pH = -1*-6.2[/tex]
[tex]pH = 6.2[/tex]
Blood:
[tex]pH = -\log(0.00000004)[/tex]
Using a calculator, we have:
[tex]pH = -1 * -7.4[/tex]
[tex]pH =7.4[/tex]
Vinegar:
[tex]pH = -\log(0.0063 )[/tex]
Using a calculator, we have:
[tex]pH = -1 * -2.2[/tex]
[tex]pH = 2.2[/tex]

Answer:
x = 16
Step-by-step explanation:
The two angles are vertical angles
Vertical angles are congruent
That being said we can create an equation
4x - 7 = 3x + 9
now we solve for x
step 1 add 7 to each side
9 + 7 = 16
-7 + 7 cancels out
now we have 4x = 3x + 16
step 2 subtract 3x from each side
4x - 3x = x
3x - 3x cancels out
we're left with x = 16
You roll a six-sided die. What is the probability that it is an odd number or less than four? Round your answer to the nearest thousandth.
Answer:
Probability is calculated as # of favorable outcomes / # of possible outcomes.
Our favorable outcomes are 1, 2, 3, 4, 5.
There are 6 total outcomes.
5/6 = 0.833
Answer:
.667
Step-by-step explanation:
There are 3 possibilities for an odd number. 1,3 and 5
For a number less than four, there are also 3 possibilities, 1,2 and 3 (Since it's not four or less)
Counting the uniquue numbers which are not repeated, you have 1,2,3,5 so the odds are 4/6 of rolling an odd or less than four number.
Since it's asking to round, I assume we need to convert to a decimal.
Decimal: .667
Percentage: 66.667%
Both answers are rounded to the thousandth.

Answer:
the first one. slope is 1/2 and y intercebt (b value) is positive 2.
Step-by-step explanation:
Answer:
y=1/2x+2
Step-by-step explanation:
This equation is linear because the graph is a straight line. Therefore, use the slope-intercept form y=mx+b to create the equation.
To find m (the slope), pick two points like (0,2) and (2,3). Find the change in y over the change in x: (y2-y1)/(x2-x1).
y2=3, y1=2, x2=2, x1=0
(3-2)/(2-0)= 1/2
This is the slope which means the equation is one of the first 2 options.
Next find b (the y-intercept) by finding the y value on the graph when x=0. When x=0, y=2. Therefore, b=2 and the final equation is y=1/2x+2

The dollar value of a car is a function, f, of the number of years, t, since the car was purchased. The function is defined by the equation f(t)=12,000(3/4)^t.
A. How much was the car worth when it was purchased? Explain how you know.
B. What is f(2)? What does this tell you about the car?
C. About when was the car worth $6,000? Explain how you know.
Answer:
1.) 12000
2.) 6750
3.) 2.41
Step-by-step explanation:
Given the Equation :
f(t)=12,000(3/4)^t. ; where, t = time ; f(t) = worth of car at time, t
When, car was purchased, t = 0
t = 0
f(0) = 12000(3/4)^0
= 12000 * 1
= 12000
2.)
f(2) ; this mean the worth of the car after 2 years :
f(2)=12,000(3/4)^t.
12000(3/4)^2
12000 * 0.5625
= 6750
When car will be worth 6000
f(t) = 6000
f(t)=12,000(3/4)^t.
6000 = 12,000(3/4)^t
6000 / 12000 = (3/4)^t
1/2 = (3/4)^t
Take the log of both sides :
Log(0.5) = log(0.75)^t
log(0.5) = tlog(0.75)
- 0.301029 = - 0.124938t
t = - 0.301029 / - 0.124938
t = 2.4094
t = 2.41 years

Un Cuarto De La Suma De Dos Números Es 81 Y Un Tercio De Su Diferencia Es 54. ¿Cuáles Son Tus Números?
Answer:
Los números son 81 y 243.
Step-by-step explanation:
Un sistema de ecuaciones lineales, también conocido como sistema lineal de ecuaciones o simplemente sistema lineal, es un conjunto de ecuaciones lineales que relacionan incógnitas entre sí.
Una solución de un sistema es una asignación de valores para las incógnitas que hace verdadera cada una de las ecuaciones. Esto es, en los sistemas de ecuaciones, se debe buscar los valores de las incógnitas, con los cuales al reemplazar, deben dar la solución planteada en ambas ecuaciones.
En este caso las variables o incógnitas son los números "x" e "y".
Un tercio es la tercera parte de una cantidad y se calcula dividiendo por 3, mientras que un cuarto es la cuarta parte de una cantidad y se calcula dividiendo por 4.
Si un cuarto de la suma de dos números es 81 y un tercio de su diferencia es 54, el sistema de ecuaciones queda definido como:
[tex]\left \{ {{\frac{x+y}{4} =81} \atop {\frac{x-y}{3} =54}} \right.[/tex]
Resolviendo por el sistema de sustitución, en primer lugar se debe despejar o aislar una de las incógnitas de una de las ecuaciones. En este caso, aislando la incógnita "x" de la primer ecuación se obtiene:
x +y= 4*81
x= 324 - y
Sustituyendo la expresión obtenida en la segunda expresión:
[tex]\frac{324-y-y}{3} =54[/tex]
Resolviendo se obtiene:
324-y-y= 3*54
324 - 2*y= 162
-2*y= 162 - 324
-2*y= -162
y= (-162)÷ (-2)
y= 81
Reemplazando este valor obtenido en la expresión x= 324 - y se obtiene:
x= 324 - 81
x= 243
Los números son 81 y 243.
