which fration is greater than 3\4
Answer: There are infinitely many fractions that are greater than 3/4. Any fraction whose numerator is greater than three and whose denominator is greater than four will be greater than 3/4. Here are a few examples:
4/5 is greater than 3/4
5/6 is greater than 3/4
6/8 (which simplifies to 3/4) is not greater than 3/4, but any fraction greater than 6/8 will be greater than 3/4. For example, 7/8, 8/9, 9/10, and so on.
In general, to determine whether a fraction is greater than 3/4, you can compare its numerator and denominator. If the numerator is greater than the denominator times 3/4 (which is the same as multiplying the denominator by 3/4 and comparing it to the numerator), then the fraction is greater than 3/4.
Step-by-step explanation:
You need a 40% alcohol solution. On hand, you have a 120 mL of a 5% alcohol mixture. You also have 55% alcohol mixture. How much of the 55% mixture will you need to add to obtain the desired solution?
In order to create a 40% alcohol solution, we must combine 280 mL of 55% alcohol combination with 120 mL of the 5% alcohol mixture.
How does drinking affect the body?Alcohol can change how the brain functions and appears by interfering with the body's communication networks. In addition to altering attitude and behaviour, these disturbances can also make it more difficult to think effectively and move to coordination.
Let's designate the quantity of a mixture of 55% booze that needs to be added "x" (in mL).
We know that the finished solution must contain 40% pure alcohol by volume in order to achieve our goal of a 40% alcohol solution.
The amount of pure alcohol in the 120 mL of 5% alcohol mixture is:
0.05 * 120 = 6 mL
When we add "x" mL of the 55% alcohol mixture, we will add:
0.55x mL of pure alcohol
In the end, we want the total amount of pure alcohol in the final solution to be:
0.40 * (120 + x) mL
Now we can set up an equation:
0.55x + 6 = 0.40(120 + x)
Simplifying and solving for "x", we get:
0.55x + 6 = 48 + 0.40x
0.15x = 42
x = 280
So we need to add 280 mL of the 55% alcohol mixture to the 120 mL of 5% alcohol mixture to obtain a 40% alcohol solution.

Choose the numbers to complete the statement about the expression. 8/10 + 2/6 Part A The numerator in the first fraction is closest to Choose... , so the fraction is nearest to Choose... . Part B The numerator in the second fraction is closest to Choose... , so the fraction is nearest to Choose... . Part C The value of the expression can be estimated as Choose... + Choose... = Choose... . 7 / 7 5 of 7 Answered
Part A: The numerator in the first fraction is closest to 8, so the fraction is nearest to 1.
To see this, we can simplify the fraction 8/10 by dividing both the numerator and denominator by the greatest common factor, which is 2. This gives us:
8/10 = 4/5
Since the numerator of the simplified fraction is closest to 5, we can estimate that the value of the first fraction is nearest to 1.
Part B: The numerator in the second fraction is closest to 2, so the fraction is nearest to 1/3.
To see this, we can simplify the fraction 2/6 by dividing both the numerator and denominator by the greatest common factor, which is 2. This gives us:
2/6 = 1/3
Since the numerator of the simplified fraction is closest to 1, we can estimate that the value of the second fraction is nearest to 1/3.
Part C: The value of the expression can be estimated as 1 + 1/3 = 1 1/3.
To see this, we can add the two estimated fractions from parts A and B:
1 + 1/3 = 3/3 + 1/3 = 4/3
Since 4/3 is closer to 1 1/3 than any other whole number or fraction, we can estimate that the value of the expression is nearest to 1 1/3.
When can a correlation coefficient based on an observational study be used to support a claim of cause and effect?a) Neverb) When the correlation coefficient is close to -1 or +1.c) When the correlation coefficient is equal to -1 or +1.d) When the scatterplot of the data has little vertical variation.
Option a) Never. A correlation coefficient based on an observational study cannot be used to support a claim of cause and effect, regardless of its value or the characteristics of the scatterplot.
Correlation does not imply causation, which means that even if two variables are strongly correlated, it does not necessarily mean that one causes the other. There may be other variables or factors that are responsible for the observed correlation, and a causal relationship cannot be established from observational data alone. To establish causality, experimental studies are typically needed, where the potential cause is manipulated and the effect is measured.

A florist charges $5 for a small floral arrangement, $7 for a medium one and $4 for a delivery fee. If you spent a total of $144, and bought 10 medium ones, how many small floral arrangements did you buy?
Answer:
14 small floral arrangements
Explanation:
First you subtract 4 from 144
144 - 4 = 140
Second you multiply the cost of a small floral arrangement and how many you have boughten.
7 x 10 = 70
You subtract the cost of 10 medium floral arrangements and how many you have boughten.
140 - 70 = 70
Finally, you divide the cost of the small floral arrangements by the remaining money.
70 / 5 = 14
The formula below, Newton's law of cooling, allows us to calculate the temperature of an object as it cools.
T = R + (T0 − R)e-kt
T = temperature of the object after t minutes
T0 = initial temperature
R = temperature of the surroundings
k = cooling rate (depends on the object and conditions)
Suppose the temperature in Denver, Colorado was 55°F when a 5°F arctic cold front moved over the state. Using k = 0.012, how long would it take a puddle of water to freeze? (Recall that water freezes at 32°F.)
With the stated cooling rate of k = 0.012, it follows that the puddle of water would ice in the arctic cold front in roughly 97.8 minutes
Simply put, what is temperature?The oscillation of a substance's components is measured by its temperature. When something is hot, it indicates that its components move relatively quickly on average. Despite having a high temperature, a substance's heat capacity is very low because it has a small number of light elements.
We can use the Newton's law of cooling formula to solve this problem.
[tex]T = R + ( To - R ) \times e ^{(-kt )}[/tex]
Let's assume that the initial temperature of the water is 55°F and the temperature of the surroundings is 5°F (due to the arctic cold front).
We are looking for the time it takes for the water to cool down to 32°F (the freezing point of water).
Therefore, we have:
T = 32°F
T0 = 55°F
R = 5°F
k = 0.012
Substituting these values into the formula, we get:
[tex]32 = 5 + (55 - 5) \times e^{(-0.012t)}[/tex]
Simplifying the equation, we get:
[tex]27 = 50 \times e^{(-0.012t)}[/tex]
Dividing both sides by 50, we get:
[tex]0.54 = e^{(-0.012t)}[/tex]
Taking the natural logarithm of both sides, we get:
ln(0.54) = -0.012t
Solving for t, we get:
t = ln(0.54) / (-0.012)
t ≈ 97.8 minutes

There are 25 boys in the class out of a total of 40 students. The fraction of students who are boys is 5/8 and the fraction of students who are girls is 3/8.
Let's start by using the information given in the problem to determine the fraction of students who are girls in the class:
Fraction of students who are girls = 1 - Fraction of students who are boys
Fraction of students who are girls = 1 - 5/8
Fraction of students who are girls = 3/8
Now we can use the fraction of girls to find the number of boys and girls in the class:
Let the total number of students in the class be x.
Number of boys = 5/8 * x
Number of girls = 3/8 * x
We know that there are 15 girls in the class, so we can set up an equation:
3/8 * x = 15
Solving for x:
x = 15 * 8/3
x = 40
So there are 40 students in the class. Now we can find the number of boys:
Number of boys = 5/8 * x
Number of boys = 5/8 * 40
Number of boys = 25

If m∠11 = 118, what is the measure of ∠8?
The measure of ∠8 is also 118º because angles opposite the vertex are equal.
To explain further, when two lines intersect, they create four angles. The angles that are directly across from each other are called angles opposite the vertex. These angles are always equal. So, if one angle measures 118 degrees, the angle opposite the vertex will also measure 118 degrees.
In this case, ∠11 and ∠8 are angles opposite the vertex. Therefore, if m∠11 = 118, then m∠8 = 118 as well.
