If you have 50g of sugar and want to make 25% sugar syrup,
how much water do you need?
Answer:
3(50 g) = 150 g
Step-by-step explanation:
If you mean 25% sugar by mass, then 1/4 of the total mass is sugar, and 3/4 is water. So you need 3 times as much water as sugar.
3(50 g) = 150 g
5 / 7/10 answer in fraction form
When we divide fractions, we multiply the first fraction by the second fraction's reciprocal.
Solving the Question\(5\div \dfrac{7}{10}\)
⇒ Multiply by the reciprocal of 7/10:
\(= 5\times \dfrac{10}{7}\)
\(= \dfrac{50}{7}\)
⇒ If you would like, you can change this into a mixed number fraction. The whole number value from 50/7 is 7. 7 times 7 is 49, which is 1 less than 50. 1 is the numerator and 7 is the whole number:
\(= 7\dfrac{1}{7}\)
Answer\(\dfrac{50}{7}\) or \(7\dfrac{1}{7}\)
How many three-digit positive integers have at least one prime digit?
Answer:
210
Step-by-step explanation:
\(512=2^9 \\\) has 9 prime factors
Now, if you want to maximize the number of different prime factor, apply the following method: let \(p(n)\) be the nth prime number, in increasing order. Let \(v\) define as follow : \(v(0)=1,v(n+1)=v(n)p(n+1)\) , and find n such that \(v(n) < 1000,v(n+1) > 1000\). n will be the number of factors and v(n) your integer.
\(v(1)=2v(0)=2v(2)=3v(1)=6v(3)=5v(2)=30v(4)=7v(3)=210v(5)=11v(4)=2310\)
There you are, 210 , with only 4 different prime factors.

It is recommended that the expressions
d = 400 - 256 and
d = 256 - 400 be considered when attempting to determine how much farther Adam can see to the horizon.
The calculation for the expression is as follows:Since, the eye-level height of Pam is 256 feet above sea level, whereas the eye-level height of Adam is 400 feet above sea level.
Therefore, the formula that indicates how much farther Adam can see to the horizon should be taken to be
d = 400 - 256 and
d = 256 - 400.
This expression may be found by subtracting 400 from 256.

Step-by-step explanation:
use interval notation to express the set of real numbers $x$ that satisfies the inequality $(x 2)(x-5) < 0$.
x -2 and x 5 provide the solution to the system of inequalities.
A collection of equations with the same variables is known as a system of equations. The only difference is that you're working with inequalities rather than equations in a system of inequalities. Finding the variable values that will make each inequality true simultaneously is necessary to solve a system like this.
(x+2)(x-5) 0, according to the inequality formula.
The inequality's zeros will be provided by the inequality's zeros, as demonstrated:

When you look at the Binomial Probability formula, it shows that n C x p x q n - x
It implies that the Binomial Probability formula contains the concept of the "Combination", not Permutation. Please describe why we need to use the Combination formula to define the Binomial Probability. Why not using the Permutation?
The reason is that the binomial formula is telling us the probability of a particular number of successes. Let’s take 5 turns at bat for a baseball player who gets hits 20% of the time. We want to find the probability that he will get exactly 2 hits. He could get hits on tries 1 & 2, 1&3, 1&4, 1&5, 2&3, 2&4, 2&5, 3&4, 3&5, 4&5. There’s no difference between getting hits on the 1st & 2nd, and getting hits on the 2nd and 1st. They’re the same thing. A permutation would treat those as different, when in reality the order doesn’t matter.
The reason the Binomial Distribution is able to use a combination as oppose to a permutation is because of the symmetry of these types of problems.
Suppose you have n objects of 2 categories. x of them are in the first category and y in the second. Therefore the number of ways you can arrange these n objects is:
Since this also describes the number of ways you can arrange failures and success in a binomial problem, let’s substitute this in place of the combination:
where x = number of repeats in successes and y = number of repeats in failures
Therefore expressing the Binomial Distribution as a combination simplifies the process slightly. However, it’s important to recognize that the combination used is actually a permutation in disguise; it must be a permutation because order matters in the context of Binomial Distributions. The combination doesn’t directly explain the number of ways to arrange the successes and failures, but can be equated to the permutation that does.

The nearest thousand means "rounding of any decimal numbers to its nearest thousandth value."
Let's say that this number is x.
If we rounded x to the nearest thousand, it is 3,000.
So x>3,500
Then, if we rounded this number to the nearest hundred, which means "at the tens digit. If it is 5 or more, then round up. If it is 4 or less, then round down."
So x<3,250

The median age of the 120 people seated in the first five rows of the concert was 31.
What is value?Value is an important concept in economics and business. It is the worth of goods, services, or assets that is determined by the market or by an individual. It can be measured in terms of money, time, or effort. Value is also used to describe a person’s sense of worth or importance. Values can be seen as the principles, standards, or goals that guide an individual’s actions and decisions. Ultimately, value is subjective and is held by each person and can change over time.
The box and whisker plot provided by the sponsor shows the ages of the 120 people seated in the first five rows of the concert. The box and whisker plot shows a minimum value of 18, a maximum value of 45, a median of 31, a first quartile of 24, and a third quartile of 37. This indicates that 50% of the 120 people in the first five rows had an age of 31 or below, and 50% of the 120 people had an age of 37 or above. The median age of the 120 people seated in the first five rows of the concert was 31.

Prove that the quadratic Sequence 44:52:64; 80: will always have even terms
The sequence is will always have even numbers, is hence proved.
Given, the quadratic sequence is: 44:52:64:80
Sequences with a term are known as quadratic sequences. They can be distinguished by the fact that the first differences between terms are not equal but the second differences between terms are. Utilizing the term sum in an arithmetic progression formula, the sum of even numbers formula is achieved. The equation is Sum of Even Numbers Formula = n(n+1), where n is the total number of terms in the series.
The formula is: Tₙ = 2n² ₊ 2n ₊ 40
take 2 common
Tₙ = 2(n² ₊ n ₊ 20)

Three number are in the ratio of 1:2:3:4 If 3 is added to the first and 8 is subtracted from the third the new number will be the first and third terms of an AP whose second term is the second number find the original number.
The original three numbers are 19/5, 38/5, and 57/5.
How did we get these values?Let the original three numbers be x, 2x, and 3x, and let the common difference of the AP be d. Then, we have:
3 + d = x + 8 (1) (the new first term is x + 3, after adding 3)
3x - 8 = 2x + d (2) (the new third term is 3x - 8, after subtracting 8)
2x + d = 2(x + d) (3) (the second term of the AP is 2x)
From equation (3), we get:
d = 2x - 2d
Simplifying and substituting into equations (1) and (2), we get:
x = 19/5 and d = 12/5
Therefore, the original numbers are:
x = 19/5
2x = 38/5
3x = 57/5
And the second term of the AP is:
2x = 38/5
So, the original three numbers are 19/5, 38/5, and 57/5.

Y=-2x-4 y=1/2x +6 what is the solution of the system of equation
Answer: To find the solution of a system of equations, we can either use substitution or elimination method.
For this system of equations, we can use the substitution method:
First, we solve one equation for one of the variables. For example, we can solve the first equation for y: y = -2x - 4
Then, we substitute this expression of y into the second equation and solve for x: 1/2x + 6 = -2x - 4
We can simplify this equation by adding 2x to both sides: 1/2x + 2x + 6 = -4
And then by adding 6 to both sides: 1/2x + 2x + 12 = 2
And then by multiplying both sides by 2: x + 4x + 24 = 4
And then by simplifying: 5x = -20
Finally, we find x = -4
Now that we have found x, we can substitute it back into one of the equations to find y:
y = -2(-4) - 4 = 8 - 4 = 4
So the solution of the system of equations is x = -4 and y = 4
We can check that this solution satisfies both equations.

At an arts and crafts fair, a photographer priced a framed print at $49.50. He ended up sellingit for $45.00. Find the percent of decrease in the price of the print. Round the percent to thenearest tenth if necessary.
cost of the framed print = $49.50
selling price = $45.00
decrease = 49.50 - 45.00 = $4.5
Therefore,
\(\begin{gathered} \text{percentage decrease=}\frac{\text{decrease}}{\cos t\text{ price}}\times100 \\ \text{percentage decrease = }\frac{4.5}{49.50}\times100 \\ \text{percentage decrease = }\frac{450}{49.50} \\ \text{percentage decrease =}9.09090909091 \\ 9.09090909091\approx9.1\text{\%} \end{gathered}\)
