Determine the ratio adjacent over hypotenuse using
8. The ratio of the adjacent over the hypotenuse is 8:17
10. The ratio of the adjacent over the hypotenuse is 1:√2
Calculating the ratio of adjacent over hypotenuseFrom the question, we are to calculate the ratio of the adjacent over the hypotenuse in the given triangles
8.
Using angle A as the reference angle
Adjacent = 16
Hypotenuse = 34
Thus,
The ratio of the adjacent over the hypotenuse = 16/34
The ratio of the adjacent over the hypotenuse = 8/17
Hence, the ratio is 8:17
10.
First,
We will calculate the hypotenuse, H
From the Pythagorean theorem, we can write that
H² = 4² + 4²
H² = 16 + 16
H² = 32
H = √32
H = 4√2
Now,
Using angle A as the reference angle
Adjacent = 4
Hypotenuse = 4√2
Thus,
The ratio of the adjacent over the hypotenuse = 4/4√2
The ratio of the adjacent over the hypotenuse = 1/√2

Computer the lower Riemann sum for the given function f(x) = 4 - x^3 over the interval x E [0,1] with respect to the partition P = [0, 1/2, 3/4, 1]
Answer:
[tex]\dfrac{917}{256}=3.58203125[/tex]
Step-by-step explanation:
The Riemann sum is a method by which we can approximate the area under a curve using a series of rectangles.
The Lower Riemann Sum uses the minimum height of the rectangle on each subinterval.
As the Lower Riemann Sum is entirely below the curve, it is an underestimation of the area under the curve.
The number of partitions is the number of rectangles used.
Partitions can be of equal length or not of equal length.
Given:
Function: f(x) = 4 - x³Interval: [0, 1]Partition, P = [0, 1/2, 3/4, 1]The given partition divides the interval [0, 1] into 3 subintervals:
[0, 1/2], [1/2, 3/4] and [3/4, 1]To calculate the areas of the rectangles, multiply the width of each rectangle by its height.
The width is the difference between the x-values of each subinterval.
The height is the minimum value of the function across the subinterval. For the given function, this is the value of the function for the right side of the subinterval.
First rectangle [0, 1/2]:
[tex]\begin{aligned}\implies \left(\dfrac{1}{2}-0\right) \cdot f\left(\dfrac{1}{2}\right)&=\dfrac{1}{2} \cdot \left(4-\left(\dfrac{1}{2}\right)^3\right)\\\\&=\dfrac{1}{2} \cdot \dfrac{31}{8}\\\\&=\dfrac{31}{16}\end{aligned}[/tex]
Second rectangle [1/2, 3/4]:
[tex]\begin{aligned}\implies \left(\dfrac{3}{4}-\dfrac{1}{2}\right) \cdot f\left(\dfrac{3}{4}\right)&=\dfrac{1}{4} \cdot \left(4-\left(\dfrac{3}{4}\right)^3\right)\\\\&=\dfrac{1}{4} \cdot \dfrac{229}{64}\\\\&=\dfrac{229}{256}\end{aligned}[/tex]
Third rectangle [3/4, 1]:
[tex]\begin{aligned}\implies \left(1-\dfrac{3}{4}\right) \cdot f\left(1\right)&=\dfrac{1}{4} \cdot \left(4-\left(1\right)^3\right)\\\\&=\dfrac{1}{4} \cdot 3\\\\&=\dfrac{3}{4}\end{aligned}[/tex]
Therefore, the Lower Reimann Sum for the given function over the given interval and partitions is the sum of the area of the rectangles:
[tex]\implies \dfrac{31}{16}+\dfrac{229}{256}+\dfrac{3}{4}=\dfrac{917}{256}=3.58203125[/tex]
The two concentric circles shown have diameters a mm and b mm, where a and b are integers with a < b. The gray region between the two circles has area 48π mm2 . What is the sum of all possible values of b?
The sum of all possible values of b is 124 in the given question.
What is concentric circles?If two or more objects have a common centre, they are said to be concentric in geometry.
Concentric shapes include spheres, circles, regular polyhedral, and regular polygons because they all share a central axis. In Euclidean geometry, concentric circles always have different radii but the same centre.
The difference between the areas is [tex]$ \frac{\pi(b^2 - a^2)}{4} = 48 \pi[/tex]
Therefore b² = a² +1 92
We can write the equation as (b−a)(b+a)=192
So b−a and b+a are factors of 192
Here are the possibilities:
b−a=1, b+a=192 ;
b−a=2, b+a=96 ;
b−a=3, b+a=64 ;
b−a=4, b+a=48 ;
b−a=6, b+a=32 ;
b−a=8, b+a=24 ;
and
b−a=12, b+a=16
Add the pairs of equations and divide by 2 (as long as the sum is even): b=49; b=26; b=19; b=16; and b=14.

In this problem we find the representation of five lines (red - yellow - green - blue - black). There is a horizontal line (green), a vertical line (blue) and three oblique lines (red - yellow - black). According to analytic geometry, we find the following definitions:
Horizontal lines: y = aVertical lines: x = bOblique lines: y = m · x + b (m - Slope, b - Intercept).The slope for oblique lines is determined by secant line formula:
m = Δy / Δx
Where:
Δx - Change in independent variable.Δy - Change in dependent variable.From picture we get the following hints:
Red line crosses the y-axis at (x, y) = (0, 5).Yellow line crosses the y-axis at (x, y) = (0, 5).Black line crosses the y-axis at (x, y) = (0, - 6).Green line crosses the y-axis at (x, y) = (0, - 2).Blue line crosses the x-axis at (x, y) = (5, 0).Finally, we proceed to find the equations for each line:
Red line
Slope
m = 5 / 2.5
m = 2
Intercept
b = y - m · x
b = 5 - 2 · 0
b = 5
The equation for the red line is y = 2 · x + 5.
Yellow line

m = - 5 / 1.5
m = - 3.333

b = y - m · x
b = 5 - (- 3.333) · 0
b = 5

Answer:
7. VS = 17
8. QR = 6
9. UT = 17
Step-by-step explanation:
You have trapezoid QRTU with midsegment VS parallel to bases QR and TU. Given dimensions for two of these parallel lines, you want the measure of the third.
Segment relationshipsThe markings on the parts of segments QU and RT indicate that points V and S are their midpoints, respectively. This makes segment VS a "midsegment", one that joins the midpoints of opposite sides. As such, its length is the average of the lengths of QR and TU:
VS = (QR +TU)/2
This is the relation that is used for problem 7.
For problems 8 and 9, this is rearranged to give the values of QR and UT:
QR = 2VS -UT
UT = 2VS -QR
7. VSFrom above, ...
VS = (QR +UT)/2 = (12 +22)/2
VS = 17
8. QRFrom above, ...
QR = 2VS -UT = 2(9) -12
QR = 6
9. UTFrom above, ...
UT = 2VS -QR = 2(11) -5
UT = 17

Additional comment
You will note that the line segments form an arithmetic sequence: the difference in length between adjacent segments is the same.

Bart found 20 quadrilaterals in his classroom. He made a Venn diagram using the properties of the quadrilaterals, comparing those with four equal side lengths. (E) and those with four right angles (R). Given that a randomly chosen quadrilateral has four right angles, what is the probability that the quadrilateral also has four equal side lengths? Express your answer in percent form, rounded to the nearest whole percent.
The probability that a randomly chosen quadrilateral with four right angles will also have four equal side lengths is 25%.
What is probability?Probability is a branch of mathematics that deals with the likelihood of an event occurring. It is the measure of how likely it is that something will happen or be the case. Probability is expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. Probability can be used to calculate the chances of a certain outcome based on a set of conditions or data. Probability can also be used to make decisions and predictions about the future.
This is because of the Venn diagram that Bart created. If a quadrilateral has four right angles, then it can either have four equal side lengths (which makes it a square) or it can have four unequal side lengths. Since there are 8 quadrilaterals in the set with four equal side lengths (E) and 16 quadrilaterals in the set with four right angles (R), the probability that a randomly chosen quadrilateral with four right angles will also have four equal side lengths is 8/16, which is equivalent to 25%. Therefore, the probability that a randomly chosen quadrilateral with four right angles will also have four equal side lengths is 25%, rounded to the nearest whole percent.

Given that for every hundred pages a thickness of 1/4 inch is added to the book, then the equation is: y = 1/2 + 1/4*x
How to find the Solution?Considering that the book's front and back covers each have a thickness of 1/4 inch, adding them together results in a thickness of 1/2 inch for the book, regardless of how many pages it has.
Given that a book's thickness increases by a quarter of an inch for every hundred pages, the equation is:
y = 1/2 + 1/4*x
where y denotes the book's width and x is the number of bond paper pages printed every 100 pages. Y has a length of inches.
Equations that have the same roots or solutions are said to be equivalent.

HEL Two students created paintings for their art class. The canvas size used for each is shown.
2 rectangles: Rectangle 1 has a length of 6 feet and width of 4 feet. Rectangle 2 has a length of 3 feet and width of 2 feet.
Which statement is true about the ratios comparing the width and length of each painting?
The paintings' width to length ratios are equal because the ratio 4 to 6 is equal to the ratio 2 to 3.
The paintings' width to length ratios are equal because the ratio 6 to 4 is equal to the ratio 2 to 3.
The paintings' width to length ratios are different because the ratio 3 to 2 is not equal to 6 to 4.
The paintings' width to length ratios are different because the ratio 4 to 6 is not equal to 3 to 2.P ASAP
The statement that is true about the ratios comparing the width and length of each painting is:
The paintings' width to length ratios are equal because the ratio 4 to 6 is equal to the ratio 2 to 3.
Ratio of numbers.A ratio is a fraction which compares the values of two numbers. Such that they can be expressed as a ratio of one to the other. Example is the ratio of a to b which can be expressed as; a:b or a/ b.
From the first dimension of the canvas size, we have;
length = 6 feet
width = 4 feet
So that,
the ratio comparing the width and length = 4/ 6
= 0.6667
From the second dimensions of the canvas size, we have;
length = 3 feet
width = 2 feet
the ratio comparing the width and length = 2/ 3
= 0.6667

if the first quadrant starts on (12,11) and moves 8 units left and 7 units down where will it be
The first quadrant starts on (12,11)
If the quadrant moves 8 units left it will be located at (12-8, 11) = (4,11)
and if it moves 7 units down it will be located at (4,11-7) = (4,4)
So the new location of the quadrant is (4,4)
It's important to notice that the first quadrant starts on (12,11) and the coordinates are (x,y) where x is on the horizontal axis and y is on the vertical axis. So when it moves left it's decreasing the x value and when it moves down it's decreasing the y value
