5
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
Cathy and iris are planning trips to nine countries this year. There are 13 countries they would like to visit. They are deciding which countries to skip,how many ways are there?
Cathy and Iris have 259,459,200 ways to skip countries.
Data;
Number of countries they are planning to visit = 9Number of countries they would like to visit = 13CombinationTo solve this problem, we would have to use a mathematical procedure known as combination.
Let us calculate the number of countries that would have to skip.
[tex]13 - 9 = 4[/tex]
To decide which country they have to skip, it would be 4 out of 13.
[tex]x = ^1^3C_4 = \frac{13!}{4!}[/tex]
Let's solve this
[tex]\frac{13!}{4!} = \frac{13*12*11*10*9*8*7*6*5*4*3*2*1}{4*3*2*1}\\ \frac{13!}{4!} = 13*12*11*10*9*8*7*6*5 = 259459200 ways[/tex]

calculate the area of the figure below
Answer:
164 cm²
Step-by-step explanation:
Take the 2 shapes and find the areas
Triangle area = (bh)/2
13 × 8 × 0.5 = 52
Rectangle area = 16 × 7 = 112
Add up the areas
112 + 52 = 164
Answer:
136 cm²
Step-by-step explanation:
The composite figure is made up of a triangle and a rectangle.
Area of the triangle
[tex]\boxed{\begin{aligned}\textsf{Area of a triangle}&=\dfrac{1}{2} \times \sf base \times height\\\\ \implies \textsf{Area of $\triangle ABD$}&=\dfrac{1}{2} \times BD \times AB\\&=\dfrac{1}{2} \times (16-8) \times (13-7)\\&=\dfrac{1}{2} \times 8 \times 6\\&=4 \times 6\\&=24\; \sf cm^2\end{aligned}}[/tex]

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.
Connections Between Zeros, Factors and Graphs of Polynomial Functions
Suppose p is a polynomial function of degree n ≥ 1. The following statements are equivalent:
• The real number c is a zero of p
• p(c) = 0
• x = c is a solution to the polynomial equation p(x) = 0
• (x − c) is a factor of p(x)
• The point (c, 0) is an x-intercept of the graph of y = p(x)

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.
ali and beth divide £35 in the ratio of 2:5 what do they get
Ali gets £10
Beth gets £25
Step-by-step explanation:
The amount is divided into 7 equal parts since 2+5=7.
since Ali's name comes first, he gets 2 of the parts as the 2 is the first number in the ratio. Beth gets 5 parts, since her name is the second.
share the £35 between the 7 parts by dividing 35 by 7.
35÷7=5
Ali gets 5× £2= £10
Beth gets 5×£5 =£25
5×5=25 (Beth's portion)

Heads Equation: 1P + 1B = 14 → -2(1P + 1B = 14) → -2P - 2B = -28
Feet Equation: 2P + 4B = 30 → 1(2P + 4B = 30) → 2P + 4B = 30

Expand and simplify (2x - 5)(3x - 2)
I got -13x +10? not sure what i’m doing wrong.
Answer:
6x^2 - 19x + 10 is the answer
Step-by-step explanation:
Lets use the FOIL method to expand,
(2x - 5)(3x -2)
2x * 3x + 2x * -2 + -5 * 3x + -5 * -2
This is the expanded version of the expression above!
here is a better way of explaining it,
(2x - 5) is the first equation now lets split it up
now its 2x and -5!
now you just multiply 2x and -5 to the second equation (3x - 2)
makes sense?
Lets Simplify it,
2x * 3x + 2x * -2 + -5 * 3x + -5 * -2
6x^2 - 4x - 15x + 10
6x^2 - 19x + 10
(tip: DON'T FORGET SAY ^2 because there are 2x's in the (2x*3x) part!)
Now you just simplify!
So as a result the answer is,
6x^2 - 19x + 10

Answer:
Step-by-step explanation: we will first work out a
so 23 is the hypotenuse
a is the opposite
so what we need to do is 46sin(23) and that will give you 17.97 cm
next we will work out b
b is the adjacent
23 is the hypotenuse
so in this case we must do 46cos(23) and that will give you 42.34
last, we will work out B
a is 17.97 cm and its the adjacent
23 is the hypotenuse
so we do sin-1(17.97/23)= 51.38
