Colleen buys a robot priced at $33.If the sales tax is10%,how much tax will Colleen pay?
Answer:
$3.3 tax
Final price is 36.3
Step-by-step explanation:
Firstly, if the tax is expressed in percent, divide the tax rate by 100. You can do this by simply moving the decimal point two spaces to the left. In this example, we do 10/100 = 0.1
tax= 33 * 0.1
tax=3.3
Finally, add tax to the before tax price to get the final price including tax.
The final price including tax = 33 + 3.3 = 36.3

Step-by-step explanation:
Three sisters have ages that are consecutive odd integers. The sum of the age of the youngest and three times the age of the oldest is five less than five times the middle sister’s age.
Answer:
youngest 17
middle 19
oldest 21
Step-by-step explanation:
Three sisters have ages that are consecutive odd integers
youngest = x
middle = x + 2
oldest = x + 4
--------------------
The sum of the age of the youngest
x
and three times the age of the oldest
+ 3(x + 4)
is five less than five times the middle sister’s age
= 5(x + 2) - 5
-----------------------
x + 3(x + 4) = 5(x + 2) - 5
Distribute
x + 3x + 12 = 5x + 10 - 5
Combine like terms
4x + 12 = 5x - 5
Subtract 4x from both sides
12 = x - 5
Add 5 to both sides
17 = x
youngest x = 17
middle x + 2 = 19
oldest x + 4 = 21

Consider this function.
h(x) = (x - 2)^2+3
Which of the following domain restrictions would enable h(x) to have an inverse function?
a. x < 1
b. x ＞5
c. x < 3
d. x > 4
(Ps: all four answer and larger equal then or smaller equal then
Answer:
No inverse function: (a), (b), (c)
Inverse function exists: (d)
Step-by-step explanation:
The graph of h(x) = (x - 2)^2 + 3 is a parabola that opens upward and has vertex at (2, 3). If the entire graph is drawn, and the horizontal line test then applied, h(x) would not have an inverse, because the horizontal line would intersect the parabolic graph twice.
Note that if we restricted the domain to x ≥ 2, the resulting graph would pass the horizontal line test. This would also be true for x ≥ 3, x ≥ 4, and so on. Not so for (a) x < 1. False for x > -5. True for x < 3. True for x > 4.
No inverse function: (a), (b), (c)
Inverse function exists: (d)

Answer:
Q1: 0.88015 ~ 88.015%, are
Q2: 0.88176 ~ 88.176%, are not
Step-by-step explanation:
Okay so a simple way to do these probability ones is to add an extra space around each side
A B C D
ACCURATE 310 262 246 144 ___
NOT ACCURATE 31 51 37 12 ___
___ ___ ___ ___ ___
Now in these spaces add all the the rows and columns accordingly
A B C D
ACCURATE 310 262 246 144 _962_
NOT ACCURATE 31 51 37 12 _131_
_341_ _343_ _283_ _156_ _1093_
Now the number in the place where the additional rows meet is your total number of orders, so this is what you would use for your probability.
So we are looking for ACCURATE / ALL which is 962
Now do 962 divided by 1093 and your probability comes out to 0.88015, so as a percentage, would be 88.015%
With replacement, all variables become independent, however without replacing that changes the probability.
When the 2 orders are selected, the final number of probability changes - so it would take down the total each time, the find the mean or average of the probability for your answer.
So since there is no replacement for ACCURATE / ALL which is 962, the division instead would be by 1091, since we are taking 2 orders out and not putting them back, it brings down the total number by 2, which would make the probability come out to 0.88176, or 88.176%
what is the answer, i tried everything but i can’t seem to get the right answer
Answer:A
Step-by-step explanation: It never talks about 50 so i don't know why that is there so I think it is A because 21 dollars is more than 5+2.75, (not 100% sure but at least 85% sure)
Answer:
A
Step-by-step explanation:
The reason that this is A is because 5$ is the initial fee and you dont pay any more than that, since 21$ is the max you can afford it is going to be less than or equal to 21. and if it is 2.75$ per stop then it is the number of stops times 2.75. A is your answer.

I WILL GIVE BRAINIEST, PLEASE HELP
Answer:
A = (1, 10)
B = (4,10)
C = (4, 14)
D = (1, 16)
Step-by-step explanation:
Okay, so first, we move, or translate the quadrilateral PQRS down -8 spaces on the graph, turning old points:
P (1, -2) = (1, -10) Q (4, -2) = (4, - 10) S (1, -8) = (1, -16) and R (4, -6) = (4, -14)
Now, we need to rotate this new box into -x, y. So our new points are:
(1, -10) = (-1, 10) (4, -10) = (-4, 10) (1, -16) = (-1, 16) and (4,-14) = (-4, 14)
Now we're reflecting off the y-axis, making our x change. So for our final points:
A(1, 10) B (4,10) D(1, 16) and C(4, 14)
Hope this helps! Please check my math and comment wether this worked or not! :)

Step-by-step explanation:
78 decreased by half a number is 45 Find the number
Answer:
number is 66
Step-by-step explanation:
let the number be n , then
78 - [tex]\frac{1}{2}[/tex] n = 45 ( subtract 78 from both sides )
- [tex]\frac{1}{2}[/tex] n = - 33 ( multiply both sides by - 2 to clear the fraction )
n = 66
The required number is 66

Solve your word problem using a model. Use complete sentences to describe your model, and interpret the quotient in the context of your word problem. If you wish, you may upload a copy of your model.
The model [tex]x = \frac{6}{3}[/tex], can be used to solve the world problem representing a scenario where John wants to share 6 apples amongst his three friends. x = 2, is the quotient which is interpreted as the number of apples each of John's friend will get.
Word problem describes real world situations which can be translated into expressions as a model.
For example, if John has 6 apples and John has three friends, how many apples would each of the friend get (x) if he is to share the 6 apples amongst the three of them?
To solve this, we can model the situation as follows:
Let x represent the number of apples each friend would get (quotient).
Thus:[tex]x = \frac{6}{3}\\\\\mathbf{x = 2}[/tex]
The quotient (x) in this model can be interpreted as the number of apples each of John's friend will get.Thus, the model [tex]x = \frac{6}{3}[/tex], can be used to solve the world problem representing a scenario where John wants to share 6 apples amongst his three friends. x = 2, is the quotient which is interpreted as the number of apples each of John's friend will get.

A coin was tossed 80 times, out of which it landed on heads 60 times. What is the relative frequency of the coin toss resulting in tails?
Answer : 25%
Step-by-step explanation : If a coin was tossed 80 times and it landed 60 times, 80 - 60 = 20 so 20/80 were tails, let's convert that into % so 20 is 1/4 of 80 so 25%.

Your friend tried putting away the sugar for you and cannot get the 14 cups of sugar to fit in the containers! They determined you would need 9 containers to store the 14 cups of sugar.
They show you their calculations:
Answer the following questions.
What mistake did your friend make in calculating the number of containers needed?
*Hint* Look closely at the work shown to find the mistake
How many containers are needed to store the leftover sugar?
Answer:
21 containers
Step-by-step explanation:
When dividing fractions, you can multiply by the inverse of the fraction. For example, in this case, [tex]14 divided by \frac{2}{3} = \frac{14}{1}x\frac{3}{2}[/tex]. Whoever drew the calculations made the mistake of forgetting to flip the second fraction.
The actual solution of the problem is 42/2, or 21/1. 21 containers are needed to store the sugar.

this is showing 2 being divided by 9 which must give a value less than one, in this case it is .2 repeating
does any one know the Inequality Notation for this [9,∞)
Answer:
x>=9
Step-by-step explanation:
so, we can plot this on a number line
the point at 9 is a solid dot, since brackets (not parenthasis) indicates that we including the number. the shaded part of the line extends all the way to positive infinity. the shaded part means that it is a solution, while the un-shaded parts aren't solutions to [9,infinity) it is x>=9 and not x>9 because 9 is included.
x>=9 is the answer
