Write an expression in terms of x to represent the area of parallelogram PQRS
Answer:
The value of b is 5 if the parallelogram is a rectangle
Step-by-step explanation:
Mathematically, the diagonals of a rectangle are equal in value
Thus, for the given expressions to represent the diagonals of a rectangle, the two must be equal
To get the value of b that makes the two equal, we simply equate the two expressions
We have this as;
10/12(24b/5 - 36/5) = 2/3 (3b + 6)
opening the brackets, we have;
4b - 6 = 2b + 4
4b - 2b = 4 + 6
2b = 10
b = 10/2
b = 5

Answer:
C
Step-by-step explanation:
Let us rule out the first one. c+11 is not equivalent.
The second one does not work either because it is adding the two terms instead of multiplying.
The last one does not work either because again, it is adding.
C, the third one works. This is because using multiplaction, you can rearrange the order of the terms and still get the same answer.
Therefore, the third one

In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests, Paul has scored 75, 80, and 91 on the first three. What range of scores on the fourth test will give Paul a C for the semester (an average between 70 and 79, inclusive)? Assume that all test scores have a non-negative value.
Answer:
Scores between 34 and 70 on the fourth test will give Paul a C for the semester.
Step-by-step explanation:
The average is given by the sum of all scores divided by the number of scores.
In this question:
Sum of all scores: 75 + 80 + 91 + x = 246 + x
Number of tests : 4
Grade of 70:
[tex]\frac{246 + x}{4} = 70[/tex]
[tex]246 + x = 280[/tex]
[tex]x = 280 - 246[/tex]
[tex]x = 34[/tex]
Grade of 79:
[tex]\frac{246 + x}{4} = 79[/tex]
[tex]246 + x = 316[/tex]
[tex]x = 316 - 246[/tex]
[tex]x = 70[/tex]
Scores between 34 and 70 on the fourth test will give Paul a C for the semester.

heather spend 2/7 of her money buying presents. she then had €48.65 left how much had she at first?
Given :
Heather spend 2/7 of her money buying presents.
She then had €48.65 left.
To Find :
The initial amount of money she had.
Solution :
Let, initial amount she had is €x.
So,
[tex]x - \dfrac{2x}{7} = 48.65\\\\\dfrac{5x}{7} = 48.65 \\\\x = \dfrac{48.65\times 7}{5}[/tex]
x = €68.11
Therefore, initially he had €68.11 .

How can we determine inequality using position on a number line?
Answer:
To plot an inequality, such as x>3, on a number line, first draw a circle over the number (e.g., 3). Then if the sign includes equal to (≥ or ≤), fill in the circle. If the sign does not include equal to (> or <), leave the circle unfilled in.

g=3+2
g=5
f(x)=4x-3
f(x)÷x=4x÷x-3
f=4-3
f=1

A military plane is flying directly toward an air traffic control tower, maintaining an altitude of 9 miles above the tower. The radar detects that the distance between the plane and the tower is 15 miles and that it is decreasing at a rate of 750mph. What is the ground speed of the plane
Answer:
-937.5 mph
Step-by-step explanation:
Assuming this takes place in a right angled triangle. With the hypotenuse side being, d, 15 miles, the opposite side being 9 miles and the adjacent being an unknown, x.
Using Pythagoras theorem, we know that
x² = 15² - 9²
x² = 225 - 81
x² = 144
x = √144
x = 12 miles.
Again, we should know that
2xx' = 2dd', this means that
xx' = dd'
From the question, we're told that it's decreasing at d' = 750 mph. On substituting, we have
x' = dd' / x
x' = (15 * -750) / 12
x' = -11250 / 12
x' = -937.5 mile per hour
The ground speed of the plane is also decreasing at 937.5 mile per hour

Pentagon WFNSC is shown on the coordinate grid. Pentagon WFNSC is dilated with the origin as the center of dilation using the rule (x, y)→(3x, 3y) to create pentagon pentagon W'F'N'S'C'. Which statement is true? Pentagon W'F'N'S'C' is larger than pentagon WFNSC because the scale factor is greater than 1. Pentagon W'F'N'S'C' is larger than pentagon WFNSC because the scale factor is less than 1. Pentagon W'F'N'S'C' is smaller than pentagon WFNSC because the scale factor is less than 1. Pentagon W'F'N'S'C' is smaller than pentagon WFNSC because the scale factor is greater than 1.
Answer:b
Step-by-step explanation:
Option A. Pentagon W'F'N'S'C' is larger than pentagon WFNSC because the scale factor is greater than 1.
Transformation of a figure by dilation: If a point (x, y) is dilated by a scale factor 'k', image point will be given by the rule,(x, y) → (kx, ky)
If k > 1, image point will be larger than its preimage. If k < 1, image point will be smaller than its image.Given in the question,
A pentagon WFNSC is dilated following the rule of dilation as,(x, y) → (3x, 3y)
Here, k > 3 which shows that the image will be larger than the preimage.
Therefore, pentagon W'F'N'S'C' will be larger than pentagon WFNSC because the scale factor is greater than 1.
Hence, Option A will be the answer.

HELPPP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Step-by-step explanation:
The lines represent the lines of symmetry where the image can be reflected upon. Hence it is reflectional.
The dot in the middle of the image tells us that the image can be rotated about the dot to produce the exact same image. Hence it is rotational.
The answer is both rotational and reflectional.
Answer:
I broke it to phrases. Make sure to read both.
It is rotational symmetry. This is because rotational symmetry means it is able to be rotated, and looks the same. This is true with this figure. The lines demonstrate that it is an equal dimensioned 2D shape.
It is ALSO reflection symmetry because this means it can be split through the center and looks exactly the same, as if it was a reflection. This is true here too because it has the same amount of lines split through the same angle on each side making it equal. You can also see a line already going through the shape, and as you can see if you look at see side it looks equal, like a reflection.
The answer is D.
