Answer:
5 liters.Step-by-step explanation:
To solve this problem, we need to find the Greatest Common Factor (GCF) which is the greater factor possible in common for all three numbers 5000, 2500 and 245 liters.
5,000 | 2
2,500 | 2
1,250 | 2
625 | 5
125 | 5
25 | 5
5 | 5
1
So, [tex]5,000 = 2 \times 2 \times 2 \times 5 \times 5 \times 5 \times 5[/tex], [tex]2,500 = 2 \times 2 \times 5 \times 5 \times 5 \times 5[/tex]
245 | 5
49 | 7
7 | 7
1
[tex]245 = 5 \times 7 \times 7[/tex]
As you can observe, the greatest common factor is 5, because it's the greater number in common for all three numbers.
Therefore, the greatest recipient possible must be 5 liters capacity.

What is an explanatory variable?
Step-by-step explanation:
An explanatory variable is a type of independent variable. The two terms are often used interchangeably. But there is a subtle difference between the two. When a variable is independent, it is not affected at all by any other variables. When a variable isn’t independent for certain, it’s an explanatory variable.
Let’s say you had two variables to explain weight gain: fast food and soda. Although you might think that eating fast food intake and drinking soda are independent of each other, they aren’t really. That’s because fast food places encourage you to buy a soda with your meal. And if you stop somewhere to buy a soda, there’s often a lot of fast food options like nachos or hot dogs. Although these variables aren’t completely independent of each other, they do have an effect on weight gain. They are called explanatory variables because they may offer some explanation for the weight gain.
The line between independent variables and explanatory variables is usually so unimportant that no one ever bothers. That’s unless you’re doing some advanced research involving lots of variables that can interact with each other. It can be very important in clinical research. For most cases, especially in statistics, the two terms are basically the same.
An explanatory variable is an independent variable.
What is an expression?One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.
Given:
A variable is an explanatory variable.
A researcher-manipulated variable is an explanatory variable when it comes to an experiment.
It serves as a measurement of the change brought about in the response variable.
A predictor variable or an independent variable are terms that are frequently used to describe an explanatory variable.
Therefore, an explanatory variable is an independent variable.

Prana has a savings account and a chequing
account with a total balance of $85.
His parents doubled the amount in each
account and the new total balance is $170.
How much money does Prana have in each
account?
Answer:
There is no unique solution to this problem and there are infinite number of possible solutions which can satisfy these equations.
Step-by-step explanation:
Let S represents Prana's savings account and C represents Prana's chequing account.
Prana has a savings account and a chequing account with a total balance of $85.
Mathematically,
S + C = 85 eq. 1
His parents doubled the amount in each account and the new total balance is $170.
Mathematically,
2(S + C) = 170
2S + 2C = 170 eq. 2
We have two equations and two unknowns.
S + C = 85
S = 85 - C
Substitute the above equation into eq. 2
2S + 2C = 170
2(85 - C) + 2C = 170
170 - 2C + 2C = 170
2C + 2C = 170 - 170
0 = 0
So what does it mean?
it means that there is no unique solution to this problem and there are infinite number of possible solutions which can satisfy these equations.

What is the theoretical probability of not rolling a 2?
Answer:
Theoretical probability is based upon what is expected when rolling two dice, as seen in the "sum" table at the right. The theoretical probability of rolling an 8 is 5 times out of 36 rolls. The theoretical probability = 5/36 ≈ 13.9%. 3) The experiment rolled more 8's than would be expected theoretically.
Step-by-step explanation:
The theoretical probability of not rolling a 2 is 5/6.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
Assuming a fair six-sided die, the probability of rolling a 2 is 1/6.
Therefore, the probability of not rolling a 2 on a single roll of the die is:
P(not rolling a 2) = 1 - P(rolling a 2) = 1 - 1/6 = 5/6
Thus,
The theoretical probability of not rolling a 2 is 5/6.

of an hour. If Blake continued walking at the same rate, what is the distance he would travel in one hour?
Answer: 4 3/8
Step-by-step explanation:
If he walks 7/8 every 1/5 of an hour, we can multiply that by 5 to get how much he travels every hour. 7/8 * 5=35/8. 35/8 simplifies to 4 3/8

3x +12 =90 what is x
Answer:
x=26
Step-by-step explanation:
3x +12 =90
subtract 12 from each side
3x=78
divide 3 from each side
x=26
Answer:
x = 26
Step-by-step explanation:
Before we begin, we must first remember that to solve for x, we have to get the variable (x) by itself.
To start, you would first subtract 12 from the left and right side of the equation.
3x + 12 - (12) = 90 - (12)
The 12 would cancel out on the left side (12 - 12 = 0) and you would now be left with 3x = 78.
Next, you would divide the left and ride side by 3.
3x ÷ 3 = 78 ÷ 3
This gives you the answer of 1x = 26 or x = 26

Answer:
16 sq. in
Step-by-step explanation:
I think you are asking for the area. The rectangle to the right of the dotted line has dimensions of 4 by 3, so its area is 4 * 3 = 12. We know one of the small rectangle's dimensions, 2, but we don't know the height. However, we see that the difference between the heights of the two figures is 1, and we already know the height of the larger rectangle is 3, so the height of the smaller square is 2. This makes its area 2 * 2 = 4. The total area would then be 12 + 4 = 16 sq. inches. Hope this helps!

This is on my math book. Jada's neighbor said, "my age is the difference between twice my age in 4 years and twice my age 4 years ago." How old is Jada's neighbor.
Answer:
Jada’s neighbor is 16 years of age
Step-by-step explanation:
In this question, we are interested in calculating the age of Jada’s neighbor, given the information in the question.
Let the present age of the neighbor be x years
Her age in 4 years will be x + 4 years old
Her age 4 years ago was x -4 years old
Now, the difference between twice her age in 4 years minus twice her age 4 years ago is her present age.
mathematically that means;
2(x+ 4) - 2(x -4 ) = x
2x + 8 - 2x +8 = x
16-0 = x
x = 16 years

This is the equation of a line in slope intercept form
[tex]y=mx+b[/tex]
where
m is the slope
b is the y-intercept
In this problem we have
[tex]m=\frac{4}{5}[/tex]
[tex]b=-3[/tex]
therefore
The slope is [tex]\frac{4}{5}[/tex]
The slope of the given line is equivalent to 4/5.
Determining the slope of a lineThe equation of a line in slope intercept form is expressed as y = mx + b
where:
m is the slope
b is the y-intercept
Given the equation of a line y = 4/5x. - 3, we are to determine its slope
In this case, the coefficient of x is (4/5), which represents the slope of the line.
m = 4/5
Therefore, the slope of the line is 4/5.

y = 4x - 3
y= 2x + 13
Answer:
x = 9, y = 29 or (8,29)
Step-by-step explanation:
Set the equations equal to each other because they both equal y:
4x - 3 = 2x + 13
Combine like terms:
2x = 16
Divide by 2:
x = 8
Plug 8 into the x for both equations and see if the y is the same:
y = 4(8) - 3 = 32 - 3 = 29
y = 2(8) + 13 = 16 + 13 = 29
