A bicycle has a listed price of $849.955 before tax. If the sales tax rate is 6.5%, find the total cost of the bicycle with sales tax included. Round your answer to the nearest cent, as necessary.
Answer:
$905.21
Step-by-step explanation:
.065 x 849.955 = 55.25
849.955 + 55.25 = 905.205

The larger number is 8 while the smaller number is 2. The slope and y-intercept of the equations y = –x + 10 and y = 4x are different so the system has exactly one solution.
What is the equation?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
In another word, the equation must be constrained with some constraints.
As per the given system of equations,
x + y = 10, y = 4x
The slope and y-intercept of (x + y = 10 ⇒ y = -x + 10) will be -1 and 10.
The slope and y-intercept of y = 4x will be 4 and 0.
Substitute, y = 4x into x + y = 10
x + 4x = 10
5x = 10
x = 2
And, y = 4 x 2 = 8
Hence "The larger number is 8 while the smaller number is 2. The slope and y-intercept of the equations y = –x + 10 and y = 4x are different so the system has exactly one solution".

How many solutions can be found for the linear equation?
6(3x 2+4)10 = 1/2(4x+16)
Answer:
1 solution.
Step-by-step explanation:
Expanding the given linear equation.
[tex]6(3x^2+4)10 = 1/2(4x+16)\\\hfill\\180x^2+240=2x+8\\\hfill\\\\180x^2-2x+232=0[/tex]
Divide everything by 2.

There are 80 dogs and cats in the animal shelter. The ratio of dogs to cats is
5
How many of the animals are dogs?
11
A.) 30
B.)25
C.)15
D.) 36
Answer:
36 I think
Step-by-step explanation:
The number of dogs is 25
The number of cats is 55.
What is a ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
We have,
Total number of dogs and cats = 80
The ratio of dogs to cats is 5:11.
Consider the number of dogs and cats to be 5x and 11x.
We can write,
5x + 11x = 80
16x = 80
Divide both sides by 16.
x = 80 / 16
x = 5
Now,
We will substitute x = 5 to find the following:
The number of dogs:
= 5x
= 5 x 5
= 25
The number of cats:
= 11x
= 11 x 5
= 55
Thus,
The number of dogs is 25
The number of cats is 55.

Input 1 2 3 4 output -8 -11 -14 -17 what is the rule
Answer:
The function rule is: [tex]y = -3x-5[/tex]
Step-by-step explanation:
Using the given input/output values, we can take two pairs of input-output values for finding the rule.
The function is a linear function as the input and output are changing linearly.
Required pairs are:
(1,-8) and (2, -11)
The general rule for linear function is:
[tex]y = mx+b[/tex]
m is the slope of the function calculated using the formula
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Putting the values
[tex]m = \frac{-11+8}{2-1}\\m = \frac{-3}{1}\\m = -3[/tex]
Putting in equation
[tex]y = -3x+b[/tex]
To find the value of b, putting (1,-8) in the equation
[tex]-8 = -3(1) +b\\-8 = -3+b\\-8+3 = b\\b = -5[/tex]
Putting the values
[tex]y = -3x-5[/tex]
Hence,
The function rule is: [tex]y = -3x-5[/tex]
A new health drink has 110 % of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 50 mg. How many milligrams of the vitamin are in the drink? There are nothing mg of the vitamin in the drink.
Answer:
55mg
Step-by-step explanation:
In order to calculate the total number of vitamin mg are in the drink we first need to turn the percentage of vitamin mg in the drink into a decimal. We do this by dividing the percentage by 100 like so...
110 / 100 = 1.1
Now that we have the decimal value of the percentage we simply multiply it by the recommended daily allowance (RDA) for this vitamin.
1.1 * 50mg = 55mg
Finally, we can see that the new health drink contains 55mg of this vitamin.
