The number 504 is divisible by 2, 3, and 7 using the divisibility rules. It is not divisible by 5 as it does not end in 0 or 5, and not by 11 as the difference between the sum of alternating digits is not a multiple of 11.
To determine which numbers 504 is divisible by using the divisibility rules, we can examine each option provided:
2: A number is divisible by 2 if it is even, that is, if its last digit is 0, 2, 4, 6, or 8. Since 504 ends with a 4, it is divisible by 2.
3: A number is divisible by 3 if the sum of its digits is a multiple of 3. For 504, the sum of its digits is 5 + 0 + 4 = 9, which is a multiple of 3, so 504 is divisible by 3.
5: A number is divisible by 5 if its last digit is 0 or 5. Since 504 ends with a 4, it is not divisible by 5.
7: To determine divisibility by 7, there isn't a simple rule like there is for 2 or 5. However, through manual calculation or knowledge, we can confirm 504 is 7 times 72, and therefore, it is divisible by 7.
11: A number is divisible by 11 if the difference between the sum of the digits in the odd positions and the sum of the digits in the even positions is a multiple of 11 or 0. For 504, (5 - 0 + 4) = 9 which is not a multiple of 11, so 504 is not divisible by 11.
In conclusion, 504 is divisible by 2, 3, and 7.

area formula of a kite
Answer:
(pq)/2
Step-by-step explanation:
p and q are the diagonals of the kite
Answer:
Area = (1/2) * (Diagonal_1)*(Diagonal_2)
where Diagonal_1 is one diagonal in the kite
and Diagonal_2 is 2nd diagonal in the kite
Step-by-step explanation:
The diagonals of a kite intersect at right angles and one diagonal bisects the other.
so you get two triangles, with a base length of (Diagonal 1)
the height_1 = a , height_2 = b
a + b = Diagonal_2
area of one triangle in Kite = (1/2)(Diagonal_1)*a
area of second triangle in Kite = (1/2)(Diagonal_1)*b
area of kite = area of triangle_1 + area of triangle_2
area of kite = (1/2)(Diagonal_1)*a + (1/2)(Diagonal_1)*b
area of kite = (1/2)*(Diagonal_1)*(a + b)
Area of kite = (1/2) * (Diagonal 1)*(Diagonal2)

Math scores on the SAT exam are normally distributed with a mean of 514 and a standard deviation of 118. If a recent test-taker is selected at random, what is the probability the student scored 691 or greater on the exam ?
Answer:
The probability is 0.06681
Step-by-step explanation:
To calculate this, we need to calculate the standard score or z-score
Mathematically, the standard score can be calculated using the formula;
z-score = (x - mean)/SD
from the question, the mean is 514 and the standard deviation is 118
The z-score is thus = (691-514)/118 = 177/118 = 1.5
The probability we are trying to calculate is thus;
P(x ≥ 691) or P(z ≥ 1.5)
Using standard score table or calculator,
Recall, P( x < 691) = 1 - P( x ≥ 691)
Hence, P( x ≥ 691) = 1 - P( x < 691)
P( x ≥ 691) = 1 - 0.93319
= 0.06681
Final answer:
To find the probability of scoring 691 or greater on the SAT Math section, you calculate the Z-score using the given mean and standard deviation, then use this to determine the percentage of students scoring below this score, with a Z-score of 1.5 corresponding to approximately 6.68% scoring higher.
Explanation:
To determine the probability that a student scored 691 or greater on the SAT Math section, given the distribution has a mean of 514 and a standard deviation of 118, we first calculate the Z-score. The Z-score formula is Z = (X - μ) / σ, where X is the score of interest, μ is the mean, and σ is the standard deviation.
For a score of 691, the Z-score is:
Z = (691 - 514) / 118 = 177 / 118 ≈ 1.5
After calculating the Z-score, we look up this value in a standard normal distribution table or use a calculator with statistical functionalities to find the probability to the right of this Z-score. This gives us the probability of a student scoring 691 or higher on the SAT Math section.
However, without a Z-table or calculator at hand, we can approximate that a Z-score of 1.5 generally corresponds to being higher than approximately 93.32% of the distribution. Therefore, the probability of scoring 691 or greater is about 6.68% (100% - 93.32%).

I sold 32 posters for a total of 126. And I sold 48 posters for a total of 240. If the relationship between the number of posters and total earnings as linear what was the cost per print expressed as a slope
Answer:
The cost per print expressed as a slope is 7.125
Step-by-step explanation:
To calculate the cost per print, let’s envision that we have a graphical representation of cost of posters against the number of posters
We have the cost on the y-axis and the number of posters on the x axis
With the information given in the question, we shall be having two data points
Point 1 = (32,126)
point 2 = (48,240)
Now to find the slope of the line which is cost per print, we make use of both points in the slope equation.
Mathematically, slope m will be
m = y2-y1/x2-x1
Thus, we have;
m = (240-126)/(48-32)
m = 114/16
m = 7.125
The cost per print expressed as a slope is 7.125

Is it possible to make a triangle that has angles measuring 90 degrees, 30 degrees, and 100 degrees? If so, describe your drawing of an example. If not, explain your reasoning.
Answer: No, it's not possible as every triangle is 180 degrees. These angles add to 220 degrees which is more than 180.
Step-by-step explanation:
This is backed by the Triangle Sum Theorem which states that the three interior angles of any triangle add up to 180 degrees.
It's impossible to form a triangle with angles measuring 90, 30, and 100 degrees because the sum of those angles exceeds 180 degrees, which violates the rule that the sum of all angles in a triangle must equal 180 degrees.
Explanation:No, it is not possible to create a triangle with angle measures of 90 degrees, 30 degrees, and 100 degrees. This is because the sum of the angles in any triangle always equals 180 degrees. If you add up 90, 30, and 100, you get a sum of 220 degrees, which exceeds the 180-degree rule of triangles.
To understand this concept better, let's take a look at an example. In a right triangle, which is a triangle where one of the angles measures 90 degrees, the other two angles must add up to 90 degrees to satisfy the 180-degree rule. So, if we have a right triangle with one angle of 90 degrees and another angle of 30 degrees, the third angle would have to be 60 degrees (180 - 90 - 30), not 100 degrees.

Cost to store
Percent of markup: 15%
Selling price: $85.10
Final answer:
To find the original cost before a 15% markup that results in an $85.10 selling price, divide the selling price by 1.15, which gives you $74.00.
Explanation:
The question is asking how to calculate the original cost of a product, given the selling price and the percent of markup. We can use the following formula to find the original cost (also known as the cost price):
Original Cost = Selling Price / (1 + Markup Percentage)
First, convert the percent of markup from a percentage to a decimal by dividing by 100:
15% / 100 = 0.15
Then apply the formula using the given selling price of $85.10:
Original Cost = $85.10 / (1 + 0.15)
Original Cost = $85.10 / 1.15
Original Cost = $74.00
Therefore, the original cost of the item before the 15% markup was applied is $74.00.

Answer:
The volume of the pentagonal prism is 1446.25
Step-by-step explanation:
First of all we need to calculate the area of the pentagon
A = area
a = apothem = 8.9
p = perimeter = 13 * 5 = 65
A = (a*p) / 2
A = (8.9 * 65) / 2
A = 578.5 / 2
A = 289.25
To calculate the volume of a pentagonal prism we have to use the following formula:
a = area = 289.25
v = volume
h = height = 5
v = a * h
we replace the values that we know
v = 289.25 * 5
v = 1446.25
The volume of the pentagonal prism is 1446.25
Two boys on bicycles start from the same place and ride in opposite directions. One ndes
one. In 3 hours, they are 27 kilometers apart. What is the rate of speed for each boy
pposite directions. One ndes twice as fast as the other
Final answer:
The rate of speed for the slower boy is 3 km/h, while the rate of speed for the faster boy is 6 km/h.
Explanation:
The rate of speed for each of the two boys can be determined by using the formula:
Rate of speed = Distance / Time
Let's assume the rate of speed of the slower boy is 'x' km/h. Therefore, the rate of speed of the faster boy is '2x' km/h, as mentioned in the question.
For the slower boy: Distance = Speed * Time. Therefore, 3x = x * 3. Solving this equation, we get x = 0 which indicates that the slower boy is not moving.
For the faster boy: Distance = Speed * Time. Therefore, 3 * 2x = 6x.
According to the question, the total distance covered by both boys is 27 km in 3 hours. So, 6x + 3 * 2x = 27. Solving this equation, we get x = 3.
Therefore, the rate of speed for the slower boy is 3 km/h and the rate of speed for the faster boy is 6 km/h.

Rita had Rs. 32000 per month. She spent 1/3 of her money on note books and 1/4 of the remainder on stationary items. How much money is left with her?
Answer:
She has Rs 16,000 left with her
Step-by-step explanation:
In this question, we are concerned with calculating how much money is left with Rita after spending the fraction of her monthly income on the things given in the question.
Firstly, she spent 1/3 of this amount on books;
Amount spent on books is thus 32,000/3 = 10,666.67
she spent a quarter of the remainder on stationary items.
Amount spent on stationary items is 1/4 * (32,000 - 10,666.67)
= 1/4 * ( 21,333.33)
= 5,333.3325
The amount of money left with her is just simply calculated by subtracting the amount she has spent from the initial amount she had
Mathematically, that would be 32,000 - (10,666.67 + 5,333.325) = approximately Rs. 16,000
