sum of two numbers is 95.theother by 15 find the numbers?
Answer:
The two numbers are 40 and 55.
Step-by-step explanation:
Let one of the numbers be x.
Then the other number is 95 - x.
If we assume x to be larger among two of them,
⇒ x - (95 - x) = 15 (as one exceeds the other by 15)
⇒ 2x = 15 + 95
⇒ x = 110 / 2 = 55
The other number is (95 - x) which is 95 - 55 = 40
Thus, the two numbers are 40 and 55

Select the response with the correct answer and an argument that correctly defends the response. Multiple choice question. A) no; The probability that Miko will win is 712 . Because 712 is greater than 512 , Miko has a greater chance of winning. B) no; The probability that Kimiko will win is 712 . Because 712 is greater than 512 , Kimiko has a greater chance of winning. C) no; The probability that Kimiko will win is 812 or 23 . Because 23 is greater than 13 , Kimiko has a greater chance of winning. D) yes; The probability that Kimiko will win is 612 or 12 . Since Kimiko's probability of winning is 12 Miko's probability of winning must also be 12 .
No; the probability that Kimiko will win is 7/12. Because 7/12 is greater than 5/12, Kimiko has a greater chance of winning.

Explanation:
The prime number sums possible are: {2, 3, 5, 7, 11}
Below is the list of ways to reach those prime sums. Focus on the items in bold. The non-bolded numbers to the left are there to keep count of things.
1+1 = 21+2 = 31+4 = 51+6 = 72+1 = 32+3 = 52+5 = 73+2 = 53+4 = 74+1 = 54+3 = 75+2 = 75+6 = 116+1 = 76+5 = 11There are 15 items in that list out of 6*6 = 36 dice rolls total.
15/36 = 5/12 is the probability of Miko winning
1 - (5/12) = 7/12 is the probability of Kimiko winning.
Those two fractions (5/12 and 7/12) aren't the same, which means the game isn't fair.
Kimiko has a better chance of winning since 7/12 is larger than 5/12.
This is why choice B is the final answer.
What method is used to find the prime factors of a number *?.
The method used to find the prime factors of a number is called prime factorization. One common method to find the prime factorization of a number is called trial division.
Here is how the trial division method works:
Divide the number by the smallest prime number (2). If the division is exact, then 2 is a prime factor of the number.
If 2 is a factor, divide the number by 2 again, and again, until the division is no longer exact. Then divide the resulting quotient by the next smallest prime number (3), and continue dividing by the smallest prime numbers (5, 7, 11, etc.) until the quotient is prime.
Repeat this process until the quotient is 1. The prime factors of the original number will be the prime numbers that were used in the divisions.

The Tangent Law may be used to calculate the height of the mountain's summit. The ratio of the opposing side to the adjacent side is defined as the tangent. Thus, the mountain's top is 3.44 kilometres high.
What is Tangent law?Tangent law is a mathematical law that states that the ratio of the tangent of an angle to the tangent of its complementary angle is equal to the ratio of the sine of the angle to the sine of its complementary angle. It can be written mathematically as:
tan(θ) / tan(90-θ) = sin(θ) / sin(90-θ)
The opposing side in this example is the height of the peak, while the adjacent side is the distance between the hotel and the summit (6.5 km).
Opposite/Adjacent = tan is the equation for the tangent law (angle of elevation). We may rewrite this equation to find the height of the mountain's peak: Adjacent = tan(angle of elevation) * Opposite.
We may calculate the height of the mountain's peak by plugging in our values: Opposite = tan(19 degrees) * 6.5 km = 3.44 km.
As a result, the mountain's top is 3.44 kilometres high.

The value of x found using the angle addition postulate is; x = 35°
What is the angle addition postulate?The angle addition postulate states that the measure of the angle formed by the non-common sides (rays) of two adjacent angles that have a common side is the sum of the two adjacent angles.
The measures of the angles in the document are;
The measure of angle STV is 75°
The measure of angle WTV is 40°
The measure of angle STW is x°
Please find attached a possible drawing representing the angles, obtained from the drawing in a similar question, and created with MS Word.
The angle addition postulate indicates that we get;
m∠STV = m∠STW + m∠WTV
Whereby angle ∠x is the same as the angle ∠STW, therefore, wse get;
m∠STV = x° + m∠WTV
Plugging in the values for the angles defined by the letters, we get the angles

300 spam emails in one month, how many total emails did
they receive?
The total emails received are 546. The solution is obtained using arithmetic operations.
What are arithmetic operations?
For all the real numbers, there are four basic mathematical operations which are:
1. Addition(‘+’) wherein the sum of the numbers is obtained.
2. Subtraction(‘-’) wherein the difference of the numbers is obtained.
3. Multiplication(‘×’) wherein the product of the numbers is obtained.
4. Division(‘÷’) wherein the quotient of the numbers is obtained.
Let the total emails received be 'x'.
We are given that for every 20 total emails a person received, they could expect to get 11 spam emails.
Now, a person received 300 spam emails in one month
So, the total emails received will be
⇒x = 20*300/11

Identify the quadratic form of
4(x-1)^2-9(x-1)=2. Than factor and solve for x.
Answer:
see explanation
Step-by-step explanation:
4(x - 1)² - 9(x - 1) =- 2
let t = x - 1 , then rewrite the expression as
4t² - 9t = - 2 ( add 2 to both sides )
4t² - 9t + 2 = 0 ← in standard form
Step 2
consider the factors of the product of the coefficient of the t² term and the constant term which sum to give the coefficient of the t- term
product = 4 × 2 = 8 and sum = - 9
the factors are - 8 and - 1
use these factors to split the t- term
4t² - 8t - t + 2 = 0 ( factor first/second and third/fourth terms )
4t(t - 2) - 1(t - 2) = 0 ← factor out (t - 2) from each term
(t - 2)(4t - 1) = 0 ← in factored form
equate each factor to zero and solve for t
4t - 1 = 0 ⇒ 4t = 1 ⇒ t = [tex]\frac{1}{4}[/tex]
t - 2 = 0 ⇒ t = 2
Step 3
Now solve for x using
t = x - 1 ( add 1 to both sides ), then
x = t + 1
t = [tex]\frac{1}{4}[/tex] , then x = [tex]\frac{1}{4}[/tex] + 1 = [tex]\frac{5}{4}[/tex]
x = 2 , then x = 2 + 1 = 3

The degree measure of each angle in the triangle are:
m angle l = 18.4
m angle J = 57.6
m angle K = 93
What is the Degree Measure?
The degree measure, also known as an angle measure, is a way to quantify the size of an angle in mathematics. The degree measure of an angle is typically represented by the symbol "degrees" (°) or simply "deg" and it is a unit of measurement.
In a triangle, the degree measure of all angles add up to 180 degrees. Therefore, we can use this property to find the degree measure of each angle in the triangle.
m angle l = (x + 5) deg
m angle J = (4x + 7) deg
m angle K = (7x) deg
So we can use the following equation:
m angle l + m angle J + m angle K = 180
(x + 5) + (4x + 7) + (7x) = 180
12x + 19 = 180
12x = 161
x = 13.4
Hence, the degree measure of each angle in the triangle are:
m angle l = (x + 5) deg = (13.4 + 5) = 18.4
m angle J = (4x + 7) deg = (413.4 + 7) = 57.6
m angle K = (7x) deg = (713.4) = 93
