On solving the provided question, we can say that so the equation formed is 1540-6x = 236 +6 x and in 108 2/3 minutes the tanks become equal with 888 gallons each
What is equation?A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.
when does tank 1 = tank 2 when there is 6 gpm
tank 1 = 1540
tank2 = 236
so the equation formed is
1540-6x = 236 +6 x
1304 = 12x
108 * 2/3 = x
6*108*2/3 = 652 gallons
236+652=888
1504-652=888
in 108 2/3 minutes the tanks become equal with 888 gallons each

What is the deadweight losscaused by the subsidy?
A.$100
B.$200
C.$3,200
D.$800
The deadweight loss caused by a subsidy is the amount of economic welfare that is lost because of the subsidy. In this example, the deadweight loss caused by the subsidy is $800. Therefore, correct option will be D.$800.
This occurs because the subsidy distorts the market by creating a price below the market equilibrium. This results in an inefficient distribution of resources as some consumers are willing to pay a higher price than the subsidized price.
Additionally, it creates an excess demand for the good, resulting in an over-allocation of resources. In this case, the deadweight loss is the difference between the market price and the subsidized price, which is $800. The deadweight loss is a negative externality of subsidies, as it reduces the overall efficiency of the market.

What is the area?Is the measure of the space occupied by a body bounded by an environment called perimeter, the same is expressed in units of squared side. Example: ft^2, m^2
The formula and procedure to solve this geometry exercise is:
A(rectangle) = length * width
Information about the problem:
A(stone) = 246 ft^2
A(fountain) = ?
Width = ?

the solution of sin(A + B) in simplest form is 27/35.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, We use the trigonometric identity as;
sin(A + B) = sin A cos B + cos A sin B
Hence, we need to find cos A and cos B.
Here, We know that;
⇒ sin A = 4/5,
By use the Pythagorean identity;
sin²A + cos² A = 1
sin² A + cos² A = 1
(4/5)² + cos² A = 1
16/25 + cos² A = 1
cos² A = 9/25
cos A = 3/5
And, we can use the identity;
tan B = sin B / cos B
to find sin B:
tan B = sin B / cos B
45/28 = sin B / √(1 - sin² B)
(45/28)² = sin² B / (1 - sin² B)
sin² B + (45/28)² sin² B = (45/28)²
sin² B (1 + (45/28)²) = (45/28)²
⇒ sin B = 3/7
Now that we have sin A, cos A, sin B, and cos B,
We can put them into the formula for sin(A + B):
sin(A + B) = sin A cos B + cos A sin B
sin(A + B) = (4/5)(45/28) + (3/5)(3/7)
sin(A + B) = 27/35
Therefore, the solution of sin(A + B) in simplest form is 27/35.

A2-4 is the second row of matrix A, so b2 = 4.
AB-1 is the first row of matrix B, so b1 = -1.
A2B-128 is the second row of matrix B, so b2 = 128.
The first column of matrix B (b1) is determined by the first row of matrix A (A1-3) and the first row of matrix B (AB-1). The first value of b1 is -3, which comes from the first row of matrix A, and the second value of b1 is -1, which comes from the first row of matrix B. The second column of matrix B (b2) is determined by the second row of matrix A (A2-4) and the second row of matrix B (A2B-128). The first value of b2 is 4, which comes from the second row of matrix A, and the second value of b2 is 128, which comes from the second row of matrix B. To summarize, the first column of matrix B is -3, -1 and the second column of matrix B is 4, 128.

Find the P-value for a right-tailed hypothesis test with a test statistic of z = 1.58. Decide whether to reject the null hypothesis H0 if the level of significance is 0.05. Choose two answers below.
Answers
A. Fail to reject H0
B. 0.943
C. Reject H0
D. 0.114
E. 0.057
Since 0.0493 < 0.05, we reject the null hypothesis and conclude that there is sufficient evidence to support the alternative hypothesis.
How to find the P-value for a right-tailed hypothesis test?The P-value for a z-score of 1.58 can be found using a standard normal table or a calculator with a cumulative distribution function. The P-value is the area to the right of the z-score, or in this case, 1 - the area to the left of 1.58.
Using a standard normal table or calculator, we find that the P-value is approximately 0.0493.
If the level of significance is 0.05, we compare the P-value to the significance level. If the P-value is less than the significance level, we reject the null hypothesis (H0), and if it's greater than or equal to the significance level, we fail to reject the null hypothesis.
Since 0.0493 < 0.05, we reject the null hypothesis and conclude that there is sufficient evidence to support the alternative hypothesis.

coordinate grid with the x axis labeled time in hours and the y axis labeled percent of battery remaining, with a line that passes through the points 0 comma 80 and 8 comma 0
What is the meaning of the y-intercept in the context of the problem?
The tablet will not have any battery remaining after 8 hours.
The tablet loses 8 percent of battery every hour.
After 80 hours, the tablet will have 0 percent of battery left.
The tablet starts with 80 percent of battery remaining.
The y-intercept in the context of the problem means that the tablet starts with 80 percent of the battery remaining.
Option D is the correct answer.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
The coordinates from the graph are:
(0, 80) and (8, 0).
Now,
(0, 80) is the y-intercept.
It means that at 0 hours, the percentage of battery is 80%.
Now,
(8, 0) is the x-intercept.
It means that after 8 hours, the percentage of battery is 0.
Thus,
The y-intercept means,
The tablet starts with 80 percent of the battery remaining.
