shine sold two tables at 9900 rupees each.he got 10% profit in one sale and 10% loss in the other.did the total sale result in a profit or loss? what percentage?
the total sale was neither a profit nor loss , 0%
Step-by-step explanation:
1st table :
100%-> 9900
110%-> 10890
10890-9900=990(earned)
------------------------------------------
2nd table :
100%->9900
90%-> 8910
9900-8910=990(lost)
990-990=0
hence the total sale was neither a profit nor loss , 0%

Solve the simultaneous equations by substitution
5x+6y=−11
5x=2y−3
Answer:
y= -1, x= -1
5x+6y=-11
-(5x-2y=-3)
8y=-8
y=-8/8
y= -1
5x+6(-1)=-11
5x-6 = -11
5x=-11+6
5x=-5
x=-5/5
x=-1
The required solution of the simultaneous equation is x = -1 and y = -1.
Given that,
To solve the given simultaneous equation,
5x+6y= −11
5x = 2y −3
Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
here,
5x = 2y −3 - - - - - (1)
5x+6y= −11
By substitution, from equation 1
2y - 3 + 6y = -11
8y = -8
y = -1
Now,
5x = -2 - 3
x = -1
Thus, The required solution of the simultaneous equation is x = -1 and y = -1.

Step-by-step explanation:
Orchid wants to retile her bathroom floor, which has an area of 40 square feet. She is deciding between two types of custom tiles. The square tile is One-half foot by One-half foot and costs $0.45 per tile. The rectangular tile is 2 feet by One-fourth foot and costs $0.80 per tile.
Answer:
b. She should choose the rectangular tiles because the total cost will be $8 less.
Step-by-step explanation:
Which tile should Orchid choose to minimize costs? Explain.
a. She should choose the square tiles because the total cost will be $8 less.
b. She should choose the rectangular tiles because the total cost will be $8 less.
c. She should choose the square tiles because the total cost will be $14 less.
d. She should choose the rectangular tiles because the total cost will be $14 less.
Area of a square tile = 1/2 × 1/2
= 1/4
= 0.25 square feet
Area of rectangular tile = 2 × 1/4
= 2/4
= 0.5 square feet
Number of square tile needed = Area of the bathroom floor / Area of the square tile
= 40 square feet / 0.25 square feet
= 160
Number of square tile needed = 160
Cost of square tile needed = number of tiles × cost per tile
= 160 × $0.45
= $72
Cost of square tile needed = $72
Number of rectangular tile needed = Area of the bathroom floor / Area of the rectangular tile
= 40 square feet / 0.5 square feet
= 80
Number of rectangular tile needed = 80
Cost of rectangular tile needed = number of tiles × cost per tile
= 80 × $0.80
= $64
Cost of rectangular tile needed = $64
Cost of square tile needed = $72
Cost of rectangular tile needed = $64

An oblique cylinder has a radius of 16 meters and a volume of 5,120(pi) cubic meters. Use Cavalieri’s Principle to solve for the height of the solid.
20 meters
25 meters
50 meters
250 meters
Answer: 20 meters
Step-by-step explanation:
We are told that an oblique cylinder has a radius of 16 meters and a volume of 5,120 pi cubic meters. We will use volume of oblique cylinder to find the height of our given cylinder. volume of a oblique cylinder= πr²hUpon substituting our given values in above formula we will get,5,120π m³ = π ( 16 m² × h )
5,120π m³ = π × 256 m² × h
Let us divide both sides of our equation by 100 pi.Therefore, height of our given oblique cylinder is 20 meters.

For which of the following conditions is it not appropriate to assume that the sampling distribution of the sample mean is approximately normal?

A random sample of 8 taken from a normally distributed population

A random sample of 10 taken from a population distribution that is skewed to the right
C
A random sample of 75 taken from a population distribution that is skewed to the left
A random sample of 75 taken from a population distribution that is skewed to the left
D
A random sample of 100 taken from a population that is uniform
Answer:
C
Step-by-step explanation:
Using the Central Limit Theorem, it is found that the option in which is it not appropriate to assume that the sampling distribution of the sample mean is approximately normal is:
C) A random sample of 10 taken from a population distribution that is skewed to the right
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.In option C, there is an skewed variable and a sample size less than 30, hence, the Central Limit Theorem is not applicable.

The angle of elevation from a park bench 724 feet from the base of the Gateway Arch in St. Louis, Missouri is 22°. How tall is the Gateway Arch, rounded to the nearest whole number?
Answer:
Gateway Arch is [tex]292.46[/tex] feet tall
Step-by-step explanation:
As we know,
the horizontal distance from the gate of the Arch to the bench [tex]= 724[/tex] feet
The angle of elevation is [tex]22[/tex] degree
Let H be the height of the gate be "H"
Tanθ= Perpendicular/Base
Substituting the given values in above equation, we get -
[tex]tan 22 = \frac{H}{724} \\H = 724 * tan 22\\H = 724 * 0.404\\H = 292.46[/tex]feet

Divide 64 by multiple numbers, and if they divide evenly that’s how many will be in each bag for the number of bags (number you divided by). For example, dividing 64 by 8 (bags) would be 8 cookies in each bag. You can do this with multiple numbers as long as it goes in evenly

Aiden earned $50 in interest in six
months. If his savings account has a
rate of 5%, how much did Aiden
start with in his account?
9514 1404 393
Answer:
$2000
Step-by-step explanation:
The amount of interest is given by the formula ...
I = Prt
where P is the principal invested, r is the annual rate, and t is the number of years. Here, we want to find P when I = 50, r = 0.05, and t = 1/2.
50 = P(0.05)(1/2)
P = 50/(0.05·1/2) = 2000
