Given ABCD as marked, what additional information would help you to prove that ABCD is a square? Pls I rlly need help
Answers

Answer:
a. AC ≅ BD
Step-by-step explanation:
All four sides are marked as being the same length. This means the figure is a parallelogram and a rhombus.
Diagonals bisect each other in any parallelogram. They are perpendicular, and bisect the corner angles, in any rhombus. Choices b, c, and d add no new information.
In order to show the figure is a square, you must show this rhombus is a rectangle: the diagonals must be the same length. That is you must show ...
AC ≅ BD
_____
Additional comment
You may be given problems with coordinates, and asked to show the figure is a parallelogram, rectangle, rhombus, or square. Often, the problem is given with the intent that you use slope and length formulas on the given points to prove opposite sides are parallel and the same length. IMO, these problems are much simpler if you show the appropriate relation exists between the midpoints, slopes, and lengths of the diagonals.

2.The marked price of television is Rs2000.If 13 percentage tax was levied, after allowing 10 percentage discount, find the final price.Single choice.
(2 Points)
Answers
Answer:
Final price = $2034
Step-by-step explanation:
Given the following data;
Marked price = $2000
Tax = 13%
Discount = 10%
To find the final sales price;
First of all, we would calculate the discount price
Discount price = 10/100 * 2000
Discount price = 20 * 10 = $200
New Price = marked price - discount price
New Price = 2000 - 200 = 1800
Next, we calculate the tax on the product;
Tax = 13/100 * 1800
Tax = 0.13 * 1800
Tax = $234
Finally, we would determine the final price;
Final price = marked price + Tax
Final price = 1800 + 234
Final price = $2034

Amy deposits S500 into an account that pays simple interest at a rate of 5% per year. How much Interest will she be paid in the first 4 years?
Answers
Answer:
She will be paid $100 in interest in the first 4 years.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
Amy deposits $500 into an account that pays simple interest at a rate of 5% per year.
This means that [tex]P = 500, I = 0.05[/tex]
How much Interest will she be paid in the first 4 years?
This is E when [tex]t = 4[/tex]. So
[tex]E = P*I*t = 500*0.05*4 = 100[/tex]
She will be paid $100 in interest in the first 4 years.

The company's expenses and sales will both total $2944 once they have sold 736 oz of links
Step-by-step explanation:
cost: y = 736 + 3x
revenue: y = 4x
y = y, so using substitution
4x = 3x + 736
x = 736
They will therefore need to sell 736 oz of links, and when plugging in 736 as x into both the equations:
y = 736 + 3(736) = 2944
y = 4(736) = 2944

A report about how American college students manage their finances includes data from a survey of college students. Each person in a representative sample of 793 college students was asked if they had one or more credit cards and if so, whether they paid their balance in full each month. There were 500 who paid in full each month. For this sample of 500 students, the sample mean credit card balance was reported to be $825. The sample standard deviation of the credit card balances for these 500 students was not reported, but for purposes of this exercise, suppose that it was $195. Is there convincing evidence that college students who pay their credit card balance in full each month have a mean balance that is lower than $907, the value reported for all college students with credit cards?
Required:
a. Carry out a hypothesis test using& significance level of 0.01.
b. State the appropriate null and alternative hypotheses.

Answer:
Following are the responses to the given question:
Step-by-step explanation:
Test statistic:
[tex]t=\frac{(825-905)}{\frac{205}{\sqrt{(500)}}}[/tex]
[tex]=\frac{(-80)}{\frac{205}{22.36}}\\\\=\frac{(-80)}{9.16}\\\\=-8.73[/tex]
Let the p-value=0
We reject H0 because of the p-value <0.01. We have evidence that college kids who pay their credit card bills in full per month have a mean balance of less than $905.

Emilio is drawing a graph that shows the weight of a baby elephant during the first 6 months of its life. What is the meaning of the point shown on the graph?
Ruby's Weight
A graph has age (months) on the x-axis, and weight (pounds) on the y-axis. A point is at (1, 80).
Answers
Using the function concept, it is found that the meaning of the point is that the weight of the elephant during the first month is of 80 pounds.
What is a function?In a function, represented by a set of ordered points (x,y), one value of the input x can be related to only one value of the output y.
In this problem, x is the age in months, while y is the weight in pounds, hence the meaning of point (1,80) is that the weight of the elephant during the first month is of 80 pounds.
