180 marbles are in the jar.
What is an Arithmetic operation?Combining operands with a single arithmetic operator specifies an arithmetic operation. The built-in functions ADD, SUBTRACT, DIVIDE, and MULTIPLY can also be used to specify arithmetic operations. in general, we use PEMDAS for calculating various arithmetic operations.
Given 25% of the marbels ar red. and also given 45 marble are red.
Hence Total marble will be,
Total marbles = [tex]\frac{45* 100}{25}[/tex] = 180.
Therefore the total number of marbles in the jar is 180.

Answer:
If a dozen donuts costs 6.00 dollars, one donut costs half a dollar.
0.50 x n = c
Take the cost of a single donut, times it by the number of donuts your getting, and then you will know the cost.

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

Answer:

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

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%
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

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.

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.

Answer:
b
Step-by-step explanation:
The slope of b is 5.5 whereas the slope for the other three graphs are 5, so B is different from the rest.
A. (4, 0.8), so by rise over run, the slope is 4/0.8=5.
B. (55, 10), so 55/10=5.5.
C. (20, 4), so 20/4=5.
D. (50, 10), so 50/10=5.
Since B is the only graph with a slope of 5.5 and the other graphs have a slope of 5, the answer is B.
Wesley has a baseball sticker with a radius of 2.3 centimeters. Determine the circumference of his baseball sticker to the nearest tenth of a centimeter.
Answer:
14.4 centimeters
Step-by-step explanation:
The formula for circumference is: [tex]2\pi r[/tex]. In this case, the r (radius) is 2.3. Multiply it by 2 to get the diameter or 4.6. Then multiply 4.6 x [tex]\pi[/tex] (pi) to get 14.444. This rounded to the nearest tenth of a centimeter is 14.4.
Note:
I used 3.14 for [tex]\pi[/tex] (pi).

If you randomly select a card from a well-shuffled standard deck of 52 cards, determine the probability that the card you
select is a 6.
a) Write your answer as a reduced fraction.
b) Write your answer as a decimal, rounded to the nearest thousandth.
c) Write your answer as a percent. Round to the nearest tenth of a percent as needed.
Answer:
a. 1/13
b. 0.077
c. 7.7
Step-by-step explanation:
a. there are 4 of the 6 in a deck of cards so the probability of taking this cards from the deck of 52 cards is 4/52. Given you 1/13.
Probability is the chance of an event to occur from a total number of outcomes.
The answer in the reduced fraction is 1/13
The answer in decimal is 0.077
The answer as a percentage is 7.7 %
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Number of cards = 52
The number of cards randomly selected = 1
The number of cards that is 6 in a deck of 52 cards:
= 4
i.e
6 of spade
6 of diamond
6 of hearts
6 of club
Now,
The probability that a randomly selected card from a deck of
52 cards is 6:
= Number of cards that is 6 / Total number of cards
= 4 /52
The answer in the reduced fraction of 4/52 is 1/13
The answer in decimal:
= 4/52
= 0.0769
Rounding to its nearest thousandth.
= 0.077
The answer as a percent:
= 4/52 x 100
= 0.0769 x 100
= 7.69 %
Rounding to the nearest tenth.
= 7.7 %
Thus,
The answer in the reduced fraction is 1/13
The answer in decimal is 0.077
The answer as a percentage is 7.7 %
