66-19.8 = 46.2
66 x 0.05 = 3.3
46.2 + 3.3 = 49.5
B
If you discount them by 30%, you will only pay 100% - 30% = 70% of their original price.
70% of $66 =
= 70% * $66
= 0.7 * $66
= $46.2
2. Now you have an item that costs $46.20, and you need to pay 5% tax on it.
$46.20 is 100% of the price of the shoes.
If you add 5% to the price, you need to pay 100% + 5% = 105% of the price.
105% of $46.20 =
= 105% * $46.20
= 1.05 * $46.20
= $48.51
Answer: $48.51

What function is represented below? graph begins in the first quadrant and decreases quickly while crossing the ordered pair 2, 1. Then the graph begins to decrease slowly as it approaches the x axis. f(x) = one fourth to the power of x plus 2 f(x) = one fourth to the power of x + 2 f(x) = one fourth to the power of x minus 2 f(x) = one fourth to the power of x − 2
Answers
It is a decreasing function that when x= 2, (1/4) is raised to the zero power which is 1, which is what the point (2,1) asks for.
Answer:
The represented function is :
[tex]f(x)=(\frac{1}{4})^{x-2}[/tex]
Step-by-step explanation:
[tex]1.\thinspace f(x)=(\frac{1}{4})^x +2[/tex]
And the equation must pass through (2,1) as given,
But, f(2) = 2.0625 ≠ 1 so this is not the required function.
[tex]2.\thinspace f(x)=(\frac{1}{4})^{x+2}[/tex]
And the equation must pass through (2,1) as given,
But, f(2) = 0.0039 ≠ 1 so this is not the required function.
[tex]3.\thinspace f(x)=(\frac{1}{4})^x -2[/tex]
And the equation must pass through (2,1) as given,
But, f(2) = -1.94 ≠ 1 so this is not the required function.
[tex]4.\thinspace f(x)=(\frac{1}{4})^{x-2}[/tex]
And the equation must pass through (2,1) as given,
We see, f(2) = 1 so this is the required function and the corresponding graph of the function is attached below :

can 0.91919191 be written as a fraction?
Answers
Final answer:
Yes, 0.91919191 can be written as a fraction. The fraction form is 91919191/9999999.
Explanation:
Yes, 0.91919191 can be written as a fraction. To convert a repeating decimal to a fraction, we can use the following steps:
Let x be the repeating decimal.Multiply both sides of the equation x = 0.91919191... by a power of 10 that moves the decimal point to the right of the repeating part (8 digits in this case): 10000000x = 91919191.91919191...Subtract the original equation (x) from the new equation (10000000x) to eliminate the repeating part: 10000000x - x = 91919191.91919191... - 0.91919191...Simplify the equation: 9999999x = 91919191Divide both sides of the equation by 9999999 to solve for x: x = 91919191/9999999Therefore, 0.91919191 can be written as the fraction 91919191/9999999.
choose the ratio that you would use to convert 5.5 pounds to ounces
Answers
Thus, multiply 5.5 pounds by (16 oz / 1 pound). "pounds" cancels, leaving you with "88 oz."
Answer:
A. 16 ounces/1 pound
Step-by-step explanation:
Remember that: 1 pound (lb) is equal to 16 Ounces (oz).
Then you have to find a ratio to convert 5.5 pounds to ounces.
If you write: 5.5 pounds, you have to find a ratio that eliminates pounds in order to get ounces:
5.5 pounds*16 ounces/1 pound
In this way pounds in the numerator is eliminated with pounds from the denominator and the result you get is in units of ounces.
5.5 pounds*16 ounces/1 pound=88 ounces

Let x be the number of successes throughout n independent repetitions of a random experiment having probability of success p=1/4. determine the smallest value of n so that p(1<=x)>=0.7
Answers
To answer problems like this you have to use binomial:
P (x > 1) = 1 – p (0 < x < 1) > .7
So:
1 – p (0) – p (1) > .7
1 – (3/ 4) ^n – (3/ 4) ^n (n – 1 ) (1/ 4) > .7
Therefore n > 5.185, and the smallest value of n so that we can satisfy the given condition is 6 (rounded up)
if the coefficient of determination for a data set is 0.25 and the SSE for the data set is 24, what is the SST for the data set?
Answers
Answer: SST for the data set is 32.
Step-by-step explanation:
Since we have given that
Coefficient of determination = R² = 0.25
Value of SSE = 24
We need to find SST.
As we know the formula for "Coefficient of determination":
[tex]R^2=1-\dfrac{SSE}{SST}[/tex]
We will put the above mentioned value:
[tex]0.25=1-\dfrac{24}{SST}\\\\0.25-1=-\dfrac{24}{SST}\\\\-0.75=-\dfrac{24}{SST}\\\\SST=\dfrac{24}{0.75}\\\\SST=32[/tex]
Hence, SST for the data set is 32.

On a survey mission,a pilot flew out to a parcel of land and back in 7h. The rate flying out was 120mph. The rate flying back was 90mph.how far away was the parcel of
Answers
To find the distance, multiply the speed by the time for each leg of the trip and add them together to get the total distance of 735 miles.
Explanation:To find the distance to the parcel of land, we can use the formula Distance = Speed x Time. Since the pilot flew out and back, we can calculate the distance for each leg of the trip and then add them together.
Distance going out = Speed x Time = 120 mph x (7/2) hours = 420 miles
Distance coming back = Speed x Time = 90 mph x (7/2) hours = 315 miles
Total distance = Distance going out + Distance coming back = 420 miles + 315 miles = 735 miles

factor a number, variable, or expression out of the trinomal shown below
Answers
Now, let's try to find the greatest common factor of the three terms, which would be 3. One way to do this would be to take each term and break it down using prime factorization, which would look like this:
6x^2= 2*3*x*x
-12x= -1*3*2*2*x
9= 3*3
When you look at the numbers when they are broken down, they all seem to share one factor, which is 3. This would be the greatest common factor you would factor out of the trinomial, and when you do so it should look like this
3(2x^2-4x+3) which would be your answer

What's the answer to find y when x=9 if y varies directly as the square of x ,and y =100 when x= 5
Answers
y = kx²
where "k" is the constant of variation you need to solve for first.
when y = 100 ; x = 5
100 = k(5)²
100 = 25k
100/25 = k
4 = k
Now you can solve for y when x = 9
y = 4(9)²
y = 4(81)
y = 324
soymeal is 14 percent protein cornmeal is 7 percent protein how many pounds of each should be mixed together in order to get 280-lb mixture that is 9 percent protein
Answers
You need a total of 280 lb, so that gives us one equation.
s + c = 280
Now we use the protein to write another equation.
The protein in s lb of soymeal is 0.14s.
The protein in c lb of cornmeal is 0.07c.
The protein in 280 lb of 0.09% protein mix is 0.09(280).
This gives us a second equation.
0.14s + 0.07c = 0.09(280)
Now we solve the two equations as a system of equations.
s + c = 280
0.14s + 0.07c = 0.09(280)
Solve the first equation for s and plug in tot eh second equation.
s = 280 - c
0.14(280 - c) + 0.07c = 25.2
39.2 - 0.14c + 0.07c = 25.2
-0.07c = -14
c = 200
Now we substitute c = 200 in the first equation to find s.
s + 200 = 280
s = 80
Answer: 200 lb of soymeal and 80 lb of cornmeal
