of a $719.99
Answer:
■ Sales tax: $36.00
■ Cost/Price before ST: $719.99
■ Total Cost/Price including ST: $755.99
Step-by-step explanation:
Answer: $755.99
Step-by-step explanation: The first step in finding how much an item or product costs with tax is to take the price of the product and multiply it by the percentage of sales tax to find out how much the tax costs. The next step is to take this cost of the tax and add it to the original price of the product. This gives you your final cost. This gives us the following equations.
In this problem the sales tax is 5%, which is equal to 0.05
(719.99) (0.05) = 35.9995
35 + 719.99 = 755.9895
The answer we get from the equations is 755.9895. Rounding to the nearest penny, or hundredth space, gives us our final answer of $755.99

A town doubles its size every 60 years. If the population is currently 1,100, what will the population be in 180 years ?
Answer: The population would be a total of 8,800 people.
Step-by-step explanation: Currently speaking, a town's population is 1,100 people in total. Since it doubles every 60 years, it would double 3 times in total, because 180 / 60 equals 3. 2 x 1,100, then 2 x 2,200, and then 2x 4,400, gives you 8,800.

The measurements of two sides of a triangular playground are 24 feet and 30 feet. Which length could be the measurement of the third side of the triangular playground?
Answer: 7 feet
Step-by-step explanation: I did it trust
The length measurement of the third side of the triangular playground whose two sides are 24 ft and 30 ft long should be more than 6 but less than 54.
What is triangle inequality theorem?
Triangle inequality theorem of a triangle says that the sum of the two sides of a triangle is always greater than the third side.
Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,
(a+b)>c
(b+c)>a
(c+a)>b
There is a triangular playground. The measurements of two sides of a triangular playground are 24 feet and 30 feet.
Suppose the length of the measurement of the third side of the triangular playground is c meters.
As the two sides are 24 ft and 30 ft long. Thus, by the triangle inequality theorem,
[tex]24+30 > c\\54 > c[/tex]
For the sides 24 ft and c ft,
[tex]24+c > 30\\c > 30-24\\c > 6[/tex]
Thus, the length measurement of the third side of the triangular playground whose two sides are 24 ft and 30 ft long should be more than 6 but less than 54.

may not be real numbers. Our final theorem in the section gives us an upper bound on the number
of real zeros.
Theorem 3.7. Suppose f is a polynomial of degree n ≥ 1. Then f has at most n real zeros,
counting multiplicities.
Theorem 3.7 is a consequence of the Factor Theorem and polynomial multiplication. Every zero c
of f gives us a factor of the form (x − c) for f (x). Since f has degree n, there can be at most n of
these factors. The next section provides us some tools which not only help us determine where the
real zeros are to be found, but which real numbers they may be.
We close this section with a summary of several concepts previously presented. You should take
the time to look back through the text to see where each concept was first introduced and where
each connection to the other concepts was made.

The graph of y = square root of x has been translated to the right 3 units and down 9 units. What is the equation of the translated graph?
A. y = 3 + +9
B. y = 9-3+3
C. y=3-√9 - x
D. y = -9+VT - 3
The translated function is:
g(x) = √(x - 3) - 9
How to find the translation?
The transformations used here are:
Horizontal translation:
For a general function f(x), a horizontal translation of N units is written as:
g(x) = f(x + N).
If N is positive, the shift is to the left.If N is negative, the shift is to the right.Vertical translation:
For a general function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N.
If N is positive, the shift is upwards.If N is negative, the shift is downwards.So, if we have a translation of 3 units right and 9 units down, this would be written as:
g(x) = f(x - 3) - 9
Replacing f(x) by the actual function we get:
g(x) = √(x - 3) - 9

A rectangle has a width that is 3 meters more than twice the length. The area of the rectangle is 44 and square. What are the length and the width of the rectangle?
Answer:
8x11/2= 44 it's 44
Step-by-step explanation:
A=44 = LW = (2W-3)W = 2W^2 -3W
2W^2-3W -44 = 0
(2W-11)(W+4) = 0
2W-11 = 0
2W = 11
W = 11/2 = 5 1/2 meters
L=2W-3 = 11-3 = 8
8x11/2= 44
length = 8 m, width = 5 1/2 m

Amari bought 12 mini muffins for 5.40 how many mini muffins can Amari buy with 4.00
Answer:

Step-by-step explanation:
*Bolded is important*
1. To help you get a better feel of the wording, let me give you an example:
The Walmart Franchise costs 5$ each. If I have 10$, how much franchises can I buy? See, it becomes simpler. It's 2.
This is what it is asking here:
If he has $5.40, and he can buy 12 mini muffins, we just need to find the cost of these mini muffins to solve the second part.
2. Solve
To find the solution to this equation, I will give you another example.
If I like drinking water, and I can buy 2 Pools of water for 2 dollars, how much does each pool of water cost?
It costs $1, which is not hard to solve.
What did we do to get the answer of $1? We divided. We divided 2/2 to get one. We have to do the same in this case.
Money is x and muffins is m.
Hence the equation is:
y = x/m, or in this case,
y=5.40/12, which will give us the cost of the muffins.
5.4/12 = $0.45.
Now, since we know the cost, we can find the answer.
To find the total amount of muffins he can buy with $4, we have to
divide.
X is Money and C is Cost per muffin. Hence, the equation is:
y = x/c or,
y = 4/0.45 which equals 8.8888888888888889.
Now, you cant buy 8/9 of a muffin. You can only buy a whole.
So he can buy 8 muffins.
3. Confirm
Lets confirm that this is true for the first equation:
5.40/0.45= 12, which is what the equation states.
So 4/0.45 = 8.899 is how much he could buy, but he can only buy 8 because, again, you cant buy 8/9 of a muffin
y = 8.
13. Rearrange this formula to make x the subject.
Y=2x/5
Step-by-step explanation:
[tex]y = \frac{2x}{5} [/tex]
crossmultiply
[tex]5y = 2x[/tex]
divide both side by 2, to make x alone
x = 5y / 2

The distance from the earth to the moon is 3.84 x 105 km
a) Find this distance in metres.
b) How long would it take a spaceship to travel to the moon from earth if its average speed was 400 ms l?
Part (a)
Answer: [tex]3.84 \times 10^8 \text{ meters}[/tex]---------------------
Explanation:
Multiply by 1000 to go from km to meters.
This is because 1000 m = 1 km.
Multiplying by 1000 in scientific notation means we add 3 to the exponent 5. The 3 is because 1000 = 10^3.
So the [tex]3.84 \times 10^5 \text{ km}[/tex] becomes [tex]3.84 \times 10^8 \text{ meters}[/tex]

Answer in scientific notation: [tex]9.6\times10^{5} \text{ seconds}[/tex]
---------------------
Work Shown:
[tex]\text{distance} = \text{rate}*\text{time}\\\\\text{time} = \frac{\text{distance}}{\text{time}}\\\\\text{time} = \frac{3.84 \times 10^8 \text{ meters}}{400 \ \text{ m}/\text{s}}\\\\\text{time} = \frac{3.84 \times 10^8}{4 \times 10^2} \text{ seconds}\\\\\text{time} = \frac{3.84}{4}*\frac{10^{8}}{10^2} \text{ seconds}\\\\\text{time} = 0.96 \times 10^{8-2} \text{ seconds}\\\\\text{time} = 0.96\times 10^{6} \text{ seconds}\\\\[/tex]
[tex]\text{time} = (9.6\times10^{-1})\times10^{6} \text{ seconds}\\\\\text{time} = 9.6\times(10^{-1}*10^{6}) \text{ seconds}\\\\\text{time} = 9.6\times10^{-1+6} \text{ seconds}\\\\\text{time} = 9.6\times10^{5} \text{ seconds}\\\\\text{time} = 960,000 \text{ seconds}\\\\[/tex]

Which graph represents the function f(x) = 2/x-1 +3
Answer:
Bottom left
Step-by-step explanation:
The limit as x approaches infinity is 3, so there is a horizontal asymptote at 3. So eliminate top left and bottom right.
Also, the fraction 2/(x-1) is undefined when x=1 (since the denominator is 0), so there is a vertical asymptote at x=1. Eliminate top right
So, your answer is the bottom left graph.
