you and three friends share a sushi boat at House of Kobe the cost of the boat is $50 you each also pay for a soft drink that is $2.39 what is the total cost of the meal after you pay 6% tax
ANSWER
$63.13
EXPLANATION
We have that the cost of the boat is $50.
Each of you and your friends (that is four of you) will pay for a soft drink that cost $2.39 each.
The cost of the soft drinks will therefore be:
4 * 2.39 = $9.56
Adding the cost of the boat, total cost will be:
$9.56 + $50 = $59.56
Now, we have to add a tax of 6%, so we find 6% of total cost:
[tex]\frac{6}{100}\cdot\text{ 59.56 = \$3.57}[/tex]Finally, add the tax to the cost:
$59.56 + $3.57
= $63.13
You pay a total of $63.13 (including tax)

Answer:
24° , 72° , 84°
Step-by-step explanation:
sum the 3 angles and equate to 180 , that is
x + x + 12 + x - 48 = 180
3x - 36 = 180 ( add 36 to both sides )
3x = 216 ( divide both sides by 3 )
x = 72
Then the measure of the 3 angles are
x = 72°
x + 12 = 72 + 12 = 84°
x - 48 = 72 - 48 = 24°
2. Zandile invests her Christmas bonus for R 875.00 in a bank that offers

have earned after 6 years? I want the interest
After 6 years, Zandile earns an interest of rupees 608.9 after investing her Christmas bonus for R 875.00 in a bank that offers interest rates of 9% p.a. compounded half-yearly.
What is interest?The simplest way to calculate interest is as a percentage of the principal. For instance, if you agreed to borrow $100 from a friend with 5% interest, the interest you would pay would only be 5% of $100: $100(0.05) = $5.
What is compound interest?Compound interest is when an amount receives interest on top of it each time interest is paid on the original amount. The principal (original) sum and the interest that has already accrued over the course of previous periods are used to calculate compound interest.
Here,
Principal amount= 875
Rate of interest= 9% pa
Compounding= half-yearly (2/year)
Time= 6 years
A = P(1 + r/n)ⁿᵇ
A=final amount
P=initial principal balance
r=interest rate
n=number of times interest applied per time period
b=number of time periods elapsed
A=875(1+9/6)⁶*²
A=₹1,483.90

Given:
A table is on sale for 38% off, The sale price of table is $527.00.
To find:
The regular price of the table.

To solve this problem, we need to use the basic formula of sales price and discount:
Sale price = $527.00
Discount percentage= 38%
[tex]\begin{gathered} \text{sale price = cost price - discount }\times\text{ \lparen cost price \rparen} \\ \\ 527=cp-\frac{38}{100}(cp) \\ \\ 527=\frac{62}{100}(cp) \\ \\ cp=\frac{52,700}{62} \\ \\ cp=850 \end{gathered}[/tex]From here we can say that the Cost-price / Regular price of the table is equal to $850.

The linear function that passes through the two points (-6, -2) and (-9, -1) is defined by the rule:
y = -(1/3)*x - 4
How to find the linear function with the given points?The general linear function in the slope-intercept form:
y = m*x + k
Where m is the slope (also called rate of change) and k is the intercept of the y-axis.
If we know that the line passes through two points (a, b) and (c, d) then the slope of the function is:
m = (d - b)/(c - a)
So with only two points, we can find the slope.
In this case, the line passes through the points (-6, -2) and (-9, -1) , then the slope is:
m = (-1 +2)/(-9 + 6) = 1/-3 = -1/3
Then the slope is m = -1/3
So the linear function is something like:
y = (-1/3)*x + k
To find the value of k i will use the pint (-9, -1), replacing these values we get:
-1 = -(1/3)*-9 + k
-1 = 3 + k
-1 - 3 = k
-4 = k
So the linear function that passes through these points is:
y = -(1/3)*x - 4

10700 dollars?
The simple interest formula is A = P(1+r t) then the value of t =33.2210 years.
What is meant by simple interest?Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest.
The simple interest formula is equal to
A = P(1+r t)
where, A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
P = $ 3300
A = $ 10700
r = 6.75 % = 6.75 / 100 = 0.0675
substitute in the formula above
$10700 = 3300(1+0.0675 t)
simplifying the above equation, we get
Divide both sides by 3300
[tex]$\frac{3300(1+0.0675 t)}{3300}=\frac{10700}{3300}$$[/tex]
Simplifying the above equation, we get

Subtract 1 from both sides
[tex]$1+0.0675 t-1=\frac{107}{33}-1$$[/tex]
Simplifying the above equation, we get
[tex]$0.0675 t=\frac{74}{33}$$[/tex]
Divide both sides by 0.0675
[tex]$\frac{0.0675 t}{0.0675}=\frac{\frac{74}{33}}{0.0675}[/tex]

A falling object travels a distance given by the formula d = 4t + 6t?, where d is measured in feet and t is measured in seconds.

If a falling object travels a distance given by the formula d = 4t + [tex]6t^{2}[/tex] where d is the measured in feet and t is measured in seconds, then the time taken by the object to travel 68 feet is 3.0496 seconds
The formula of the object traveling a distance d = 4t + [tex]6t^{2}[/tex]
Where d is the distance traveled in feet
t is the time taken in seconds
Here
The distance traveled = 68 feet
Therefore the equation will be
68 = 4t + [tex]6t^{2}[/tex]
[tex]6t^{2} +4t-68=0[/tex]
We have to solve quadratic equation [tex]\frac{-b+/-\sqrt{b^2-4ac} }{2a}[/tex]
a = 6
b = 4
c = -68

t = 3.0496 seconds
Hence, if a falling object travels a distance given by the formula d = 4t + [tex]6t^{2}[/tex] where d is the measured in feet and t is measured in seconds, then the time taken by the object to travel 68 feet is 3.0496 seconds

Based upon the testing results above, of the 11.69 million people who live in Ohio, what is the bestestimate for the number of people who would test positive for the virus?
To find the probability for the number who tested positive we divide the positive cases between the total of the covid tests and then mutiply by 100.
P = (8,533/68,811)* 100
P = 12.400, the nearest hundredth of a percent is 12.
11690000 people who live in ohio and the testing results is that 12% of this people would test positive for the virus. so we need to find percentage 12 for 11690000.

Write an equation for the line in point-slope form.
The equation of the line by using slope value is: y = x -9
What is slope of a line?
The slope of a line explain the steepness of the line segment. It is ration of the coordinates of the y-axis and the vertical coordinates of the x-axis. Depending upon the slope value, it is classified as whether lines are parallel or perpendicular.
According to the question, the given parameters for the line segment is as written below:
Equation of a line = x + 2 and the coordinate points = (6, -3): (x = 6; y = -3)
Now, by using standard equation for the line segment: y = mx + c
where, 'm' is the slope; c is the y-intercept; (x, y) are coordinates
Substituting given values that is slope and y-intercept in the standard equation, we get:
y = mx + c
⇒ -3 = (1)(6) + c
⇒ c = -3 - 6 = -9
Therefore, the value of the y-intercept is: c = (-9)
equation of the line by substituting the value of the y-intercept as well as slope value:
y = (1)x + (-9) = y = x -9
Hence, the equation of the line by using slope value is: y = x -9
