Therefore , it will take 1.71 hours to fill the empty cistern if all the pipes are running.
What is equation?equation: a statement that two expressions having variable- and/or number-filled expressions are equivalent. Since equations are essentially questions, the search for a way to respond to them has spurred the development of mathematics.
Here,
Let's assume that the pipelines in this instance are "a" to drain the water in 6 hours, "b" to fill the water on its own in 4 hours, and "c" to fill the water in 5 hours.
Therefore, if "a" can empty it in 6 hours, it has only completed 1/6 of the task in that time. In 6 hours, "a" would have completed 6/6 or 1 whole, the entire task, and the cistern would have been fully filled, but in 1 hour, it has only accomplished 1/6 of that.
In an hour, "b" has completed barely a quarter of the task.
In that case, "c" has only completed 1/5 of the task in an hour.
Now, assuming it took "x" hours, if "a," "b," and "c" are running, and "a" is draining while b & c filling it up.
The cistern must be filled in "x" hours, thus after 1 hour, all three have completed only 1/x of the task.
well, let's add their rates, to see what we get then.
=> 1/4 + 1/5 -1/6= 1/x
=> 15 + 20 - 10 / 60 = 1/x
=>35/60 =1/x
=> x=60/35
=>1.71 hours
Therefore , it will take 1.71 hours to fill the empty cistern if all the pipes are running.

The markup is the difference between the selling price and the cost price, expressed as a percentage of the cost price.
Markup = ((Selling price - Cost price) / Cost price) x 100%
In this case, the cost of materials is $80 and the selling price is $150, so the markup is:
Markup = ((150 - 80) / 80) x 100%
Markup = (70 / 80) x 100%

The relationship between angles R and R is: B. m∠M > m∠R.
What is the Relationship of the Angles of Two Triangles?The size of the angles in a triangle is related to the length of the side they are opposite to. That is, the largest angle is opposite the longest side and vice versa. This is the basis of the relationship of the corresponding angles of two triangles with two equal sides, and a third unequal sides.
In the image given, we see that two corresponding sides of the two triangles are equal to each other, MN = RS, and MP = RT.
Since the side that is opposite to the third angle in triangle MNP is greater than the side that is opposite to the third angle in triangle RST, NP > ST, therefore, it follows that the size of angle M that is opposite to side NP would be greater than the size of angle R that is opposite to side ST.

After the decimal point it goes the tenth then the hundredth place. So that will be the second number after the decimal point. The question gives you a number and asks you to round to the hundredth place so you are going to first look what number is in the hundredth place and then look in the number after it. 3 is the number in the hundredth place and 6 is the number after. The rule is if the number is less than 5 the number stays as is and if the number is greater than 5 you round the number up. Since the number after the 3 is 6 you are going to round up.

Richard found 93 - 67 by adding up on the open number line. Is he correct? Explain. Then write an addition equation to show how you could check his work
The addition equation is 93 - 67 = 26 in the number line.
What is number line?
A number line is an image of numbers plotted on a straight line, either horizontally or vertically. We can compare numbers and execute simple arithmetic operations on them easily by writing the numbers down on a number line. The starting point of a number line is often regarded as zero (0). These numbers to the left of zero are all negative while the numbers just on right of zero are all positive. As a result, we can argue that on a number line, the value of numbers grows as we approach the right. The numbers on the right are therefore larger than the ones on the left, according to this statement.
The entire question is depicted in the picture that is attached.
Richard added 26 to 67 by first marking point 67 on the line, then adding 2 tens and 2 threes until he reached 93 as opposed to subtracting 67 to 93 by subtracting 6 tens and 7 ones starting at point 93, which results in 26.
Take note that 26 is equal to 10 plus 10 plus three additional times.
To verify his work, we add the following: 67 + 26 = 93, which is also written as 93 - 67 = 26.
Hence the addition equation is 93 - 67 = 26.

can someone help me solve this step by step? I am very confused
To solve this problem, we need to use the basic trigonometric identities, which state that for any angle x:
sin^2(x) + cos^2(x) = 1
1 + tan^2(x) = sec^2(x)
1 + cot^2(x) = csc^2(x)
We can use these identities to simplify the expression (sin0 + cos0) = 2 + sec0 csc0/Sec0 CSC0. First, we note that sin0 + cos0 = 1, because sin^2(0) + cos^2(0) = 1. So, the left-hand side of the equation becomes 1 = 2 + sec0 csc0/Sec0 CSC0.
Next, we note that sec0 = 1/cos0 and csc0 = 1/sin0, so we can rewrite the right-hand side of the equation as 1 = 2 + 1/cos0 * 1/sin0 / Sec0 CSC0.
Then, we note that Sec0 = 1/cos0 and CSC0 = 1/sin0, so the right-hand side of the equation becomes 1 = 2 + 1/cos0 * 1/sin0 / 1/cos0 * 1/sin0. This simplifies to 1 = 2 + 1/cos0^2 * 1/sin0^2, which simplifies further to 1 = 2 + 1/cos0^2 / sin0^2.
Finally, we use the identity 1 + cot^2(0) = csc^2(0) to replace 1/sin0^2 with 1 + 1/cos0^2, which gives us 1 = 2 + 1/cos0^2 / (1 + 1/cos0^2). Solving for 1/cos0^2, we get 1/cos0^2 = -1. This means that cos0 = 0, which is not a valid value for the cosine function. Therefore, the original equation has no solution.

What is Division?A division is a process of splitting a specific amount into equal parts.
Given that the Bob has 42 cookies and he wants to give all his cookies away to each of his six friends.
Which means Bob has to split 42 cookies among his 6 friends equally.
He gives each friend the same amount he concludes each friend will receive 42÷6 = 8 cookies.
Bob is incorrect if we split 42 cookies to six friends, then each friend will get 7 cookies not 8 cookies.
Hence, Bob divided incorrectly, 42÷6 = 7 is correct.

The length of x is 30.
The length of y is 30.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = 1/ cosec x
Cos x = 1/ sec x
Tan x = 1/ cot x or sin x / cos x
Cot x = cos x / sin x
We have,
Right triangle.
One angle = 90°
Other two angles = 45°
Hypotenuse = 30
The other two sides are x and y.
Now,
Tan 45 = x/30
1 = x/30
x = 30
Tan 45 = y/30
y = 30
Thus,
30 is the length of x.

Which matrix equation can be used to solve the system? {(2x+3y=4),(x+y=7):}
Use matrices created using the coefficients of the unknowns and their related determinants to apply Cramer's rule.
How should a matrix equation be written?Three easy actions must be taken in order to describe this system as a matrix:
First, create a matrix with all the coefficients. An acronym for this is a coefficient matrix.
Multiply this matrix by the system setup's variables in another matrix.
In another matrix, place the solutions on the other side of the equal sign.
A = [[2, 3], [1, 1]]
A_{x} = [[3, 4], [1, 7]] d
A{y} = [[2, 4], [1, 7]]
det (A) = 2-3=-1
det (Ax) = 14 - 4 =10
Delta_{y} = [[2, 4], [1, 7]] det (A7), 22-2012
x = (det (Ax))/(det (A)) = 10
