Answer:
In regular polygons, if the number of sides, n, is odd, the lines of symmetry will pass through a vertex and the half of the opposite side.
Step-by-step explanation:
This is equivalent to say that a perpendicular bisector of a side of the regular polygon bisects the angle of the opposite vertex to the side, and divide the polygon into two symmetrical parts.
The base of a rectangular prism has an area of 19.4 square meters and the prism has a volume of 306.52 cubic meters. Write an equation that can be used to find the height h of the prism. Then find the height of the prism.
Answer:
15.8
Step-by-step explanation:
The formula would be V = Bh, the Base being LxW.
Since we already know the base and volume, we can substitute it into the formula.
306.52 = 19.4(h). Divide by 19.4, and you get 15.8 as your answer.

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For Example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Total Eggs = 94
Each box Hold= 6 eggs
So, number of boxes required to hold 94 eggs
= 94 / 6
= 15.66
Hence, smallest number of boxes she needs is 15.67

Answer:
bottom right
Step-by-step explanation:
Your answer is the bottom right number line.
To answer this question we should first do the calculation 1/8 - (-3/4) to find out what the final answer should be:
To subtract fractions they must have a common denominator, so we’re going to multiply -3/4 by 2 to get -6/8. This will give us:
1/8 - (-6/8) = 1/8 + 6/8 = 7/8. (this turns into + because when you subtract a negative number the minus sign cancels out)
Therefore the correct answer must land on 7/8 on the number line, which is 1 mark away from 1 because each mark represents 1/8, so your answer is the number line in the bottom right.

Rihanna wants to purchase a dishwasher and is shopping around at different stores. Which two benefits can Rihanna get from using credit instead of cash for her purchase?
(You can pick more than 1)
1. She can receive a discount on the price if she uses credit instead of paying cash
2. She can use the dishwasher while paying for it over a period of time.
3. Her cost of purchase will decrease if she uses credit instead of cash
4. She can buy the dishwasher even if she doesnt have the money now to pay for it.
5. She wont need to pay taxes on the purchase.
Answer:
4,2 I'm pretty sure those are the correct ones
Step-by-step explanation:
credit means that you can buy anything you want but your not spending your money but eventually you will have to pay it back
so she can use the dishwasher while paying for it over a period of time and she can buy the dishwasher even if she doesn't have the money now to pay for it.
if she pays it with cash then she's using her money with the credit you have to pay it over time and if you don't pay the credit you will be in BIGG trouble so pay it!!
hope it helped!! :D
She can receive a discount on the price if she uses credit instead of paying cash. She can buy the dishwasher even if she doesn't have the money now to pay for it. Hence, Option A and C are the correct options.
What is loan?A loan is a form of credit where a lender allows another party (the borrower) the use of money or property for a specified period of time.
Why does credit that offers long-term advantages exist?
If those conditions are met, a long-term loan can reduce the impact on operational cash flow, allow a debtor to borrow at a lower interest rate, reduce investor interference, and assist a business in establishing its credit worthiness.
Short-term loans are thus preferred for working capital, such as payroll, inventory, and seasonal imbalances, whereas long-term loans are typically used to purchase fixed assets, such as equipment.
Credit cards are more widely accepted and, in general, faster to use than checks. Bill payments via credit card can be made automatically, combining multiple payments into a single one.
By using a credit card with a rewards programme, you could earn rewards such as free travel.

what is the center?
the circle passes through the point (-7,-7). what is the radius?
We have been given image of circle that passes through point [tex](-7,-7)[/tex]. We are asked to find the radius of the circle.
First of all, we will find the center of the circle.
We can see that center of circle is at point [tex](-2,-1)[/tex].
Now we will use equation of circle to find radius.
[tex](x-h)^2+(y-k)^2=r^2[/tex], where, point (h,k) represents center of circle and r represents radius of circle.
Now we will substitute the coordinates of point [tex](-7,-7)[/tex] and coordinates of center [tex](-2,-1)[/tex] and solve for r as:
[tex](-7+2)^2+(-7+1)^2=r^2[/tex]
[tex](-5)^2+(-6)^2=r^2[/tex]
[tex]25+36=r^2[/tex]
[tex]61=r^2[/tex]
Switch sides:
[tex]r^2=61[/tex]
Now we will take positive square root on both sides:
[tex]\sqrt{r^2}=\sqrt{61}[/tex]
[tex]r=\sqrt{61}[/tex]
Therefore, radius of circle will be [tex]\sqrt{61}[/tex] and center is at point [tex](-2,-1)[/tex].
what is 12,447 in Scientific notation
Answer: [tex]1.2447 * 10^4[/tex]
Step-by-step explanation:
1.2447 × [tex]10^4[/tex]
( scientific notation )
Move the decimal point in your number until there is only one non-zero digit to the left of the decimal point.
Answer:
1.2447 x 10^4
Step-by-step explanation:
The answer would be 1.2447 times 10 to the fourth power because to find the first part (1.2447), move the decimal place one place to the right. (.12447-> 1.2447)
Next, count how many places are to the right of the decimal.
1.2447 = 4
So, that would get you 1.2447 times 10 to the power of 4.

How many 4-digit multiples of 5 are there?
please have a formula and don't just write them all out. Thanks.
Answer:
First 4-digit multiple of 5 is 1000. It is the least 4-digit number and it is multiple of 5.
Last 4-digit number is 9999 which is not a multiple of 5 and so are 9998, 9997, 9996. Largest 4-digit number which is multiple of 5 is 9995.
Number of 4-digit multiples of 5 = 9995 − 1000 /5 + 1 = 8995/ 5 + 1 = 1799 + 1 = 1800
Step-by-step explanation:
A number x is said to be a multiple of number n if n divides the number x
. One important observation is if x is a multiple of n then the next multiple of n is x + n
. Hence the multiples of number n occur in differences of n
Suppose x and y are multiples of n
. Number of multiples of n between x and y
including them is given by y − x / n + 1
Because for every n numbers in between x and y there is a multiple of n
Combination helps to know the number of ways objects can be arranged. The 4-digit numbers that are multiples of 5 are 1800.
What is a combination?The combination helps us to know the number of ways an object can be arranged without a particular manner. A combination is denoted by 'C'.
[tex]^nC_r = \dfrac{n!}{r!(n-r)!}[/tex]
where,
n is the number of choices available,
r is the choices to be made.
In order to make a 4 digit number divisible by five the number must end with either 5 or 0, and for the number to be a 4 digit number, it can not start with 0. therefore, the first place can be occupied by any number from 1 to 9, the second place can be occupied by any number from 0 to 9, the third number can be occupied by any number from 0 to 9, and the fourth number can be occupied by any number from 0 or 5. Thus, the possible options are,
[tex]= ^9C_1 \times ^{10}C_1 \times ^{10}C_1 \times ^2C_1\\\\= 9 \times 10 \times 10 \times 2\\\\= 1800[/tex]
Hence, the 4-digit numbers that are multiples of 5 are 1800.

How to find if a pair of figure is not dilated version of each other?Dilation of a figure will leave its sides get scaled (multiplied) by same number.
Thus, suppose if a rectangle is dilated, and its sides were of length = L and width = W, then its dilated version would be having length = Ln, and width = Wn where n is the factor of scaling.
At image B (-24, -12) and pre image B (-18, -9),
we can work out the scale factor by (-24/-18) and (-12/-9) both equal 4/3
Using the scale factor to go from the pre image to the image,
We can find C coordinate by pre image C by the scale factor.
C is (-13.5 x 4/3) and (18 x 4/3)
C is (-18, 24)
So, The scale factor is 4/3, which is the mixed numeral of 1 1/3.
To find the pre image of point A;
A is (12/(4/3)) and (-6/(4/3))
A is (9, - 4 1/2)
Hence, the true statement are;
The coordinates of C prime are (–18, 24).
The scale factor is 1 1/3 .
The coordinates of A are (9, –4.5).
