Based on the dimensions of the right triangle, the equation to be used to find the missing lengths is hypotenuse² = Known leg² + Unknown leg².
How to find a missing length on a right angled triangle?To find the missing length of a right-angled triangle, you should use Pythagoras theorem.
This theorem allows you to find the dimensions of missing leg as:
hypotenuse² = Known leg² + Unknown leg²
When you solve for the missing length, the length is:
9² = 6² + Unknown leg²

Over the last three evenings, Amy received a total of 112 phone calls at the call center. The first evening, she received 7 more calls than the second evening. The third evening, she received 3 times as many calls as the second evening. How many phone calls did she receive each evening?
Answers
Based on the relationship between the number of phone calls that Amy received for the three evenings, the number of phone calls received on each evening was:
First evening - 28 calls Second evening - 21 calls Third evening - 63 calls How to find the number of phone calls received?The first evening saw Amy receiving 7 more calls than the second evening while the third evening saw Amy receiving 3 times as many calls as the second evening.
Assuming the second evening is x, the relationship can be represented by the equation:
First evening calls + Second evening calls + Third evening calls = Total number of calls
(7 + x) + x + 3x = 112
Solving for the number of phone calls on the second evening gives:
(7 + x) + x + 3x = 112
7 + x + x + 3x = 112
7 + 5x = 112
5x = 112 - 7
x = 105 /5
= 21 calls
Number of calls on first evening:
= 21 + 7
= 28 calls
Number of calls on third evening:
= 21 x 3

Answers
The plane containing point B and parallel to the plane CDH is plane ABF.
What is defined as the parallel plane?Parallel planes are spatial planes that never intersect. The length about any line segment perpendicular both to planes connecting two parallel planes is indeed the distance between them. There are an infinite number of perpendicular line segments between two parallel planes. Two of the perpendicular segments the above are line segments AB and CD. Any line segment that is perpendicular to both planes also has the shortest distance between them.As, from the diagram we can see that there are two plane passing from point B; plane ABF and ABC.

Drag the tiles to the boxes to form correct pairs. Not all tiles will be used.
Match the function with its inverse.
Answers
The correct pairs of the functions and their inverses are given by the image at the end of the answer.
How to find the inverse function?To find the inverse function, we exchange x and y in the original function, then isolate y.
The first function that we want to find the inverse is:
f(x) = (2x - 1)/(x + 2).
Hence:
x = (2y - 1)/(y + 2)
(y + 2)x = 2y - 1
xy + 2x = 2y - 1
xy - 2y = -1 - 2x
y(x - 2) = -1 - 2x
y = (-1 - 2x)/(x - 2) (which is the inverse function).
The second function which we want to find the inverse is:
y = (x + 2)/(-2x + 1)
Then:
x = (y + 2)/(-2y + 1)
x(-2y + 1) = y + 2
-2yx + x = y + 2
-2yx - y = 2 - x
-y(2x + 1) = 2 - x
y = (x - 2)/(2x + 1) (which is the inverse function).
The third function which we want to find the inverse is:
y = (x - 1)/(2x + 1)
Then:
x = (y - 1)/(2y + 1)
2yx + x = y - 1
2yx - y = -1 - x
y(2x - 1) = -1 - x
y = (-x - 1)/(2x - 1) (which is the inverse function).
The fourth function which we want to find the inverse is:
y = (2x + 1)/(2x - 1)
Then:
x = (2y + 1)(2y - 1)
2yx - x = 2y + 1
2yx - 2y = 1 + x
2y(x - 1) = (1 + x)
y = (x + 1)/(2(x - 1)) (which is the inverse function).

Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.So, according to the given image below:
(A) m∠1 = m∠3 ⇒ Alternate angles.
(B) m∠1 + m∠2 = 180°
Reason:
R is a straight line through which line m asses making two angles m∠1 and m∠2.As we know a straight line has an angle of 180°.And since, line m divides the angle of 180° into two parts ∠1 and ∠2.So w ecam conclude that: m1 + m∠2 = 180°.(C) m∠3 + m∠2 = 180° due to: Linear Pair Axiom.
(D) m∠2 and m∠3 are supplementary because: Since a linear pair of angles always results in a straight line, their sum is always 180°.

The quotient is the outcome of the division.The quotient is the result of dividing two numbers by each other. As in the case of 8 ÷ 4 = 2, when the division produced the number 2, the outcome is the quotient. The dividend is 8 and the divisor is 4. The quotient and divisor are always less than their dividend, as you can see.So, h(t) = 24:

h(t) = - 1624 = 50 - 1616 = 50 - 2416 = 26 = 26/16t = √26/16t = 1.3secTherefore, with the help of the quotient, we know that the time the water balloon dropped from the rooftop is 1.3sec.

the equation of the regression line for the data in the table is y = 4.9 - 198 where x represents the height and y is the predicted walking speed
Answers
The numerical value of 4.9 in the equation of the regression line
[y = (4.9x - 198)] determines "for every unit change in height, walking speed increases by 4.9 m/min" since, "x" represents the height and "y" is the predicted walking speed.
As per the question statement, the equation of the regression line goes as [y = (4.9x - 198)], where "x" represents the height and "y" is the predicted walking speed.
We are required to determine, what the numerical value of 4.9 expresses in the regression line.
To solve this question, first we need to know about the formula to express the point-slope form of a line, which goes as, [(y - y₁) = m(x - x₁)], where (x₁, y₁) is a point through which the line passes, and "m" is the slope of the line, and compare this standard form to our question mentioned equation, to establish the numerical significance of 4.9.
Now, [y = (4.9x - 198)] can be written as [(y - 0) = 4.9(x - 40.41)], and comparing it to the standard point-slope form of a line, we get (m = 4.9), i.e., the slope of our concerned line of regression is 4.9.
Hence, 4.9 in 4.9x signifies "for every unit change in height, walking speed increases by 4.9 m/min" since, "x" represents the height and "y" is the predicted walking speed.

Where is the least common denominator of two fractions to product of the denominator?
Answers
When two or more fractions are provided, the least common denominator is defined as the smallest common multiple of all the common multiples of the denominators.
What is the least common denominator?The smallest number that is a common denominator for a particular set of fractions is referred to as the least common denominator (LCD). For fraction addition and subtraction, as well as comparing two or more fractions, the given fractions must have common denominators.Let's assume we have to add the fractions: (2/9)+(3/4)
We need to determine a common integer that is a multiple of both denominators, which are 9 and 4.
This common multiple will aid in the solution of the problem. As a result, the least frequent multiple for 9 and 4 is 36. As a result, the expression can be written as follows:
