hope this helps!
Step-by-step explanation:
7/6 cups of water is the mug's capacity
Step-by-step explanation:
Capacity refers to how much a container can contain.
Let x be the capacity of the mug.
According to the question, the mug is 3/7 full. This means that the mug contains 3/7 × x = 3x/7 of water.
It was further stated that the mug contains 1/2cup of water. This means that:
1/2 cup of water = 3x/7 of water in the mug
Hence;
1/2 = 3x/7
3x × 2 = 7 × 1
6x = 7
x = 7/6
Therefore, the capacity of that mug is 7/6 cups of water.
A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator
3/7 of the mug = 4/7 of a cup of water
1 mug = 4/3 of a cup of water
The capacity of the mug is 4/3 of a cup of water.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example:
1/2, 1/3 is a fraction.
We have,
A mug is 3/7 full.
The mug contains 4/7 of a cup of water.
This means,
3/7 of the mug = 4/7 of a cup of water _____(A)
The full capacity of the mug can be represented by 1
So,
Multiply 7/3 on (A).
7/3 x 3/7 of the mug = 7/3 x 4/7 of a cup of water
1 mug = 4/3 of a cup of water
Thus,
1 mug = 4/3 of a cup of water
The capacity of the mug is 4/3 of a cup of water.

Which of the following is a constant in this expression?
Which of the following lists all the coefficients in this expression?
Answer:
constant: 4
coefficent: 7, 18 (However, -1 can also be counted as a coefficient, it is just invisible!)
Step-by-step explanation:
coefficient: a numerical or constant quantity placed before and multiplying the variable in an algebraic expression
therefore, 7 and 18 are coefficients. HOWEVER, -1 can also be a coefficient to -z.
constant: a quantity or parameter that does not change its value whatever the value of the variables, under a given set of conditions.
therefore, 4 is a constant.

D. . -
Answer:
the answer is b
Step-by-step explanation:
Answer:
x = 9/4
Step-by-step explanation:
2x - x + 9 + 3x - 2 = 16
Combine like terms

Find the common factor of all of the terms of the polynomial below.
14x2 - 12x
Α. 2x
Β. 4χ2
C. 2χ2
D. 4x
Answer:
A. 2x
Step-by-step explanation:
First let's correct the problem.
Question:
[tex]14x^2-12x[/tex] is the binomial we are solving
Now, let's solve this.
We see that we have one term to the 2nd degree (shown by the exponent) and one to base degree. Therefore, the answer cannot be B or C since you cannot factor into a negative exponent.
So we now have either A. 2x or D. 4x
Let's try both of these.
Factoring out with 2x we get:
[tex]2x(7x-6)[/tex], which is perfectly fine!
Factoring out with 4x we get:
[tex]4x(3.5x-3)[/tex]
Therefore, it must be A. 2x
Alternatively, we know the factors of 14 are 1,2,7, and 14. The factors of 12 are 1,2,3,4,6, and 12. The only factor shared here is A. 2

The solution to the multiplication of surds (2√3) × (3√2) is; 6√6
We want to find; √12 × √18Let us break each of them into the factors to get;
√12 × √18 = √(4 × 3) × √(9 × 2)
Now,this can be expressed as;(√4 × √3) × (√9 × √2)
Simplifying this further gives;
(2√3) × (3√2)
Now, in surds, we know that;a√b × p√q = ap√bq
Applying the surd rule above to our question gives;(2√3) × (3√2) = 6√6

Merit pay increases happen ____.
every 3 months
every 6 months
every 12 months
whenever your employer decides
Answer:
whenever your employer decides
Merit pay, being performance pay, depends on the employer. Increment in merit pay happens: Option D: whenever your employer decides
What is merit pay?Merit pay, often known as merit raises or pay for performance, is a type of performance-based pay.
Merit pay, being performance pay, depends on the employer.
Increment in merit pay happens whenever your employer decides. It is because your performance is usually judged by someone, usually employer or a team leader which then reports to the employer usually.
So instead of monthly based increment in the merit pay, the increment happens whenever the employer (or member in power) decides to increase it. So option D is best among all the options.
Thus, increment in merit pay happens: Option D: whenever your employer decides

Select all thepairs of equivalent
expressions.
Leo is buying milk for his family for a week. He said he bought 7 kilograms of milk. Is his answer reasonable? Explain.
Answer:
First, we know that a single liter of milk weighs around 1.032 kg.
Then 7 kilograms of milk is equivalent to (almost) 7 liters of milk.
Now, this is reasonable?
Well, for a typical person, the consumption is between 0.5L and 0.75L
So 7kg of milk may less of what a typical family consumes in a week, but is not an outlier (for example, 30kg of milk or 1kg of milk per week are outliers, which are "nonreasonable") so 7 kg is a reasonable amount of milk.
Now, if the question only refers to the units he used (kg instead of liters) this does not matter, as we know, mass and volume are two different, but equivalent, ways of describing a known matter, as these are related by the density:
Density = mass/volume.
So, for a known material, if you know the mass that you have, you also know the volume.
Then using kg is reasonable in this situation.
