Answer:
68.245
Step-by-step explanation:
total cost = $81.05
10% discount is 10/100× 81.05=8.105
substract 8.105 from 81.05= 72.945
with a 6.5% sales tax
6.5/100× 72.954 = 4.7
72.945-4.7= 68.245 the actual price

Given the statement:
Little sisters are annoying.
If you are a little sister, then you are annoying. This is the_
converse
original statement
contrapositive
inverse
Hypothesis
conclusion
Answer:
conclusion
Step-by-step explanation:
We are given a single statement:
"Little sisters are annoying."
A hypothesis regarding that statement is then proposed:
You are a little sister.
The only two possible interpretations from the information given are that you either are annoying or not. Since little sisters are annoying, if you are a little sister, the only possible logical conclusion is that you are annoying.
The answer is conclusion.
It would be conclusion
“Little sisters is annoying”

The scale on a map is 1 cm:60 km. How many kilometers are represented by 2.5 centimeters on the map?
120 kilometers
105 kilometers
135 kilometers
150 kilometers
Answer:
150 km
Step-by-step explanation:
The scale tells you what real distance corresponds to a distance in the drawing. 1 cm in the drawing means 60 km of real distance.
Since 2.5 cm is 2.5 times 1 cm, it represents 2.5 times 60 km of real distance.
2.5 * 60 km = 150 km
Using the order of operations, what is the last calculation that should be done to evaluate 4(8 − 6)52 − 6 ÷ (−3)?
4(8 − 6)52 − 6 ÷ (−3)
4(2)52 − 6 ÷ (−3)
4(2)(25) − 6 ÷ (−3)
200 − 6 ÷ (−3)
200 − (−2)
Answer & Step-by-step explanation:
4(8 - 6)52 - 6 ÷ (-3)
First, subtract 6 from 8
4(2)52 - 6 ÷ (-3)
4(2)(52) - 6 ÷ (-3)
Multiply 2 by 52
416 - 6 ÷ (-3)
Divide -6 by -3.
416 + 2
Add 2 to 416
418
So, your evaluated answer would be 418.
Answer:
its 200+2
So addition is the last calculation to be done.

Write each polynomial in standard form. What is the name of the polynomial based on its degree and number of terms?
a. 3 + 5x − 4x2
b. 8x + x + 5 + x3
Answer:
Step-by-step explanation:
(a) 3 + 5x − 4x^2 should be written as −4x2 + 5x + 3. This is a QUADRATIC function.
(b) 8x + x + 5 + x^3 should be re-written first as 9x + 5 + x^3 and then as
x^3 + 9x + 5. This is a CUBING function.

Answer:
y = 1/4 x -3
Step-by-step explanation:
The y intercept ( or where it crosses the y axis ) is -3
Pick 2 points to find the slope
(0,-3) and (4,-2)
The slope is
m = (y2-y1)/(x2-x1)
= (-2 --3)/ (4-0)
= (-2+3)/4
1/4
The slope intercept form of the equation is
y = mx+b where m is the slope and b is the y intercept
y = 1/4 x -3

If f(x) = x^2 - 2x and g(x) = 6x + 4, for what value of x does (f + g)(x) = 0?
Answer:
x = -2
Step-by-step explanation:
[tex]f(x) =x^2 -2x\:\: and \:\: g(x) = 6x + 4\\(f+g)(x) = f(x) + g(x) \\(f+g)(x) = x^2 -2x+ 6x + 4\\(f+g)(x) = x^2+4x + 4\\(f+g)(x) = (x+2)^2\\ 0 = (x+2)^2...[\because (f+g)(x) =0]\\0 = x+2\\\therefore x = -2[/tex]
Answer:
x = -3 + √5 and x = -3 - √5
Step-by-step explanation:
Combine f and g:
f = x^2 -2x
+g = 6x + 4
-------------------------
(f + g)(x) = x^2 + 6x + 4
Set this result = to 0 and solve for x:
By completing the square, we get:
y = x^2 + 6x + 9 - 9 + 4, or
y = (x + 3)^2 - 5 = 0
Thus, (x + 3)^2 = 5, and:
x + 3 = ±√5, or
x = -3 + √5 and x = -3 - √5

Answer:
y= (x^2-3) + 2
Step-by-step explanation:
It is plus two on the end to go up 2 on the y axis since the question says up two units and in the parenthesis is where you can move the start of and line, exponential line, or parabola to the left or to the right. When in the parenthesis, if you do however many x's and whatever exponent there is if you plus it will go into the negatives, ot left, and minus will go positive, or right. Therefore the answer is y= (x^2-3) +2.
BTW, when writing exponents, this: ^, is an exponent sign but working on certain platforms will allow you to write them like in the image, and if it can then you should write it like that.

What is the decay factor in y = 760(0.75)3?
Answer:
Decay factor is 0.75.
Step-by-step explanation:
The given function is
[tex]y=760(0.75)^3[/tex] ...(1)
The general form of exponential decay function is
[tex]y=a(1-r)^t[/tex] ...(2)
where, a is initial amount, t is the time period, r is decay rate and (1-r) is the decay factor.
On comparing (1) and (2), we get
[tex]a=760, t=3, (1-r)=0.75[/tex]
Therefore, the decay factor is 0.75.
The library is 3.56 kilometers from Maria's house and 1.38 kilometers from Simon's house. How much farther does Maria live from the library than Simon?
Answer: 2.18 kilometres
Step-by-step explanation:
First we take down the information given to us
Maria's house to library (distance) = 3.56 km
Simon's house to library (distance) = 1.38 km
Now to get how farther Maria lived from the library compared to Simon, we subtract the distance between the library and Simon's house from the distance between the library and Maria's house
i.e
3.46km - 1.38km = 2.18km
there for Maria lived 2.18 kilometres farther from the library compared to Simon.

Find any 6 ratinol numbers between -5/6 and 5/8
Answer:
There is a variety of answers. you will find an example below
Step-by-step explanation:
To find the rational numbers between 2 fractions/rational numbers, we have to find the LCM of the denominator, which would increase the value of the numerator. This way you will have more rational numbers between the two.
- 5/6 = -40 / 48
5 / 8 = 30 / 48
Now, we can notice that there is a difference of 70 between the 2. this means you may choose 6 out of these. Here is an example(some of them are simplified)
5/16, 5/8, 7/48 , 1/6 , 2/6, -1/2.

curved surface area (green) is found by circumference multiply by height
[tex]\pi[/tex] x d x h = [tex]\pi[/tex] x (15 x 2) x 12 = 360[tex]\pi[/tex]
total surface area is
blue circle + total curved surface area (blue + green)

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). A florist currently makes a profit of $20 on each of her celebration bouquets and sells an average of 30 bouquets every week. She noticed that when she reduces the price such that she earns $1 less in profit from each bouquet, she then sells three more bouquets per week. The relationship between her weekly profit, P(x), after x one-dollar decreases is shown in the graph below. Use the graph to complete each statement about this situation. The maximum profit the florist will earn from selling celebration bouquets is $___ . The florist will break-even after ______ one-dollar decreases. The interval of the number of one-dollar decreases for which the florist makes a profit from celebration bouquets is (___,____).
Answer:
First space: 15
Second space: 20
Third space: 0
Fourth space: 20
Step-by-step explanation:
If the florist decrease x times the value of the bouquet by 1, the number of bouquets sold is 30 plus 3 times x, so we have that:
P(x) = (20 - x)*(30+3x)
P(x) = 600 +30x - 3x2
The vertical axis of the graph represents the profit P(x) of the florist.
So observing the graph, we can see that the maximum profit is 675, and occurs when the value of x is 5, that is, the price of the bouquet is 20 - 5*1 = $15
Looking again to the graph, we see that when x = 20 her profit is zero (the price of each bouquet will be 20 - 20*1 = 0)
The interval of x for which the florist have a positive profit (P(x) > 0) is between x = -10 and x = 20, but the florist cannot make a negative number of one-dollar decrease, so the lower number in the interval should be 0.
Answer:
675
