How many milliliters of a 28% sugar Solution do we need to mix with 75 milliliters of a 10% sugar solution so that the resulting mixture is a 13% sugar solution?
We need to mix 15 ml of 28 % of solution to get the resulting mixture as a 13 % sugar mixture.
Let the amount of 28 % sugar solution be x ml.
We are given that:
10 % sugar solution = 75 ml
Total solution = 75 ml + x ml
We need the solution to be 13 % sugar solution.
So, we get that:
28 % x + 10 % ( 75 ) = 13 % ( 75 + x )
28 x + 750 = 13 ( 75 + x )
28 x + 750 = 975 + 13 x
28 x - 13 x = 975 - 750
15 x = 225
x = 225 / 15
x = 15
Therefore, we need to mix 15 ml of 28 % of solution to get the resulting mixture as a 13 % sugar mixture.

Answer:
x = 21 cmStep-by-step explanation:
is a rhombus formed by 4 right triangles, let's consider the small / large couple
the triangle at the top and the triangle at the bottom are rectangles
we can solve with the Pythagorean theorem.
we find the side (cathetus) of the small onec² = 10² - 8²
c² = 100 - 64
c² = 36
c = √36
c = 6 cm
we find the side (cathetus) of the largestc² = 17² - 8²

((12-4)(3-2))^2 + square root of 64
Answer: 72
Step-by-step explanation: First step that I did was to subtract 12 and 4 to get 8. I then subtracted 3 and 2 to get 1. Then since 8 and 1 are in the parenthesis, I multiplied 8 and 1 to get 8. 8 to the 2nd power then comes out to 64. 64 adding the square root of 64 which is 8 then comes out to 64 plus 8 because the square root of 64 is 8. 64 plus 8 equals 72.

Juan and Mahdi are to run a race, but Juan can run 18 meters per second, whereas Mahdi can run 6 meters per second. If Mahdi has a 228 -meter head start, how long will it be before the faster runner catches the slower runner, if they begin at the same time? Round your answer to the nearest whole number.
Answer:
19 seconds
Step-by-step explanation:
You want to know the time it takes for Juan, running 18 m/s, to overtake Mahdi, running 6 m/s, if Mahdi has a 228 meter head start.
Closing timeThe time to close the gap between the runners will be ...
time = distance/speed
time = (228 m)/(difference in speeds) = (228 m)/(18 m/s -6 m/s)
time = (228 m)/(12 m/s) = (228/12) s = 19 s
It will take Juan 19 seconds to catch Mahdi.

The sum of three consecutive numbers is 33 more than the smallest of the numbers. Find
the numbers.
Answer:
15, 16 and 17
Step-by-step explanation:
Consecutive numbers mean numbers that are separated by 1 from each other. For example 5, 6 and 7 are three consecutive numbers and 5 is the smallest
Let the smallest number be x
Then the next consecutive number is x + 1
The next one after that is x + 2
Sum = x + x + 1 + x + 2 = x + x + x + 1 + 2 = 3x + 3
We are told that this sum is 33 more than the smallest number x
So 3x+3 = x + 33 Subtract x from both sides
3x - x + 3 = x + 33 -x
==> 2x + 3 = 33
Subtract 3 from both sides
==> 2x + 3 - 3 = 33 -3
==> 2x = 30
Divide both sides by 2
==> 2x/2 = 30/2
==> x = 15
So the smallest number is 15 and the three numbers are 15, 16 and 17
Verify by adding 15+16 +17 = 48
15 + 33 = 48 so consistent
A: The three consecutive numbers are 15, 16, 17.
Explanation:
Let x, y, z be the numbers.
x + y + z = x + 33
y = x + 1
z = x + 2
We will solve this system of equations using the substitution method.
x + x + 1 + x + 2 = x + 33
x + x + x - x = 33 - 1 - 2
2x = 30
x = 15
y = 15 + 1 = 16
z = 15 + 2 = 17
Solving for x + y + z = x + 33:
15 + 16 + 17 = 15 + 33
48 = 48
A: 15, 16, 17.

A study was performed with a random sample of 5 people from a certain city. What population would be appropriate for generalizing conclusions from the study, assuming the data collection methods used did not introduce biases?
The standard deviation is a statistic that describes the degree of volatility or dispersion in a set of numerical values. While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.
High sample size is typically crucial in order to be able to draw generalizations from a sample, aside from avoiding bias. Since the sample size is modest, it will thus be possible to draw general conclusions about the study utilizing a larger sample, in my opinion.
The size of the sample has a significant impact on whether an experiment is legitimate. The central limit theorem states that as sample size rises, the sample mean approaches the population means value.
Because of this, generalizing from just five samples regarding a population of city dwellers won't produce a result that can be generalized.
