a walking path BE in a park intersects intersects two sides of the park at their midpoints. You walk from point D to E, E to B, from B to C, and back to point D. How many yards did you walk?
Answers
Answer:
Total distance covered = 436 yards
Step-by-step explanation:
Walking path BE joins the midpoints B and E of the sides AC and AD.
By midsegment theorem,
"Line joining midpoints of two sides of a triangle is parallel and measure half of the third side"
m(BE) = [tex]\frac{1}{2}[m(CD)][/tex]
CD = 2(BE)
CD = 2(74) = 128 yd
From starting point D,
DE = 107 yd
EB = 74 yd
BC = [tex]\frac{254}{2}[/tex]
= 127 yd
CD = 128 yd
Total walking distance = DE + EB + BC + CD
= 107 + 74 + 127 + 128
= 436 yd
Total distance covered = 436 yards
Answer:
456
Step-by-step explanation:

Angle SPR and angle RPQ are complementary. Find the measure of angle RPQ.
Answers
Answer:
53 degrees
Step-by-step explanation:
Complimentary angles are angles whose sum equals 90 degrees.
90-37 = 53
Answer:
m∠RPQ = 53°
53 degrees
Step-by-step explanation:
When two angles are complementary angles, it means they add up to 90 degrees (Ex: a 10° angle and 80° angle would be complementary).
Therefore, if ∠SPR and ∠RPQ are complementary, then
m∠SPR + m∠RPQ = 90°
since you are given that m∠SPR = 37°, you can plug that in for m∠SPR to find m∠RPQ:
m∠SPR + m∠RPQ = 90°
37° + m∠RPQ = 90°
m∠RPQ = 90° - 37°
m∠RPQ = 53°

Two triangles are similar if the sides of both triangles can be represented as equivalent ratios. The height of the shaded triangle is 37.5 units.
Given that:
[tex]\overline{UD} = 25\sqrt 3[/tex]
[tex]w = 50\sqrt3[/tex]
See attachment
First, we calculate side length [tex]\overline{LD}[/tex].
This calculated using tangent trigonometry ratio
[tex]\tan(\theta) = \frac{Opposite}{Adjacent}[/tex]
So, we have:
[tex]\tan(90-\frac{\pi}{3}) = \frac{\overline{UD}}{\overline{LD}}[/tex]
[tex]\tan(90-30) = \frac{\overline{UD}}{\overline{LD}}[/tex]
[tex]\tan(60) = \frac{\overline{UD}}{\overline{LD}}[/tex]
This gives:
[tex]\tan(60^o) = \frac{25\sqrt3}{\overline{LD}}[/tex]
Make LD the subject
[tex]\overline{LD}= \frac{25\sqrt3}{\tan(60^o)}[/tex]
[tex]\overline{LD}= \frac{25\sqrt3}{\sqrt 3}[/tex]
[tex]\overline{LD}= 25[/tex]
Next, we calculate side length [tex]\overline{DR}[/tex].
This calculated using tangent trigonometry ratio
[tex]\tan(\theta) = \frac{Opposite}{Adjacent}[/tex]
So, we have:
[tex]\tan(\frac{\pi}{6}) = \frac{\overline{UD}}{\overline{DR}}[/tex]
This gives:
[tex]\tan(30^o) = \frac{25\sqrt3}{\overline{DR}}[/tex]
Make DR the subject
[tex]\overline{DR}= \frac{25\sqrt3}{\tan(30^o)}[/tex]
[tex]\overline{DR}= \frac{25\sqrt3}{1/\sqrt 3}[/tex]
[tex]\overline{DR}= 25\sqrt3 \times \sqrt 3[/tex]
[tex]\overline{DR}= 25 \times 3[/tex]
[tex]\overline{DR}= 75[/tex]
Calculate side length [tex]\overline{LR}[/tex]
[tex]\overline{LR} = \overline{LD}+\overline{DR}[/tex]
[tex]\overline{LR} = 25+75[/tex]
[tex]\overline{LR} = 100[/tex]
Because the triangle has a uniform thickness, the small and the big triangle are similar triangles.
So, the height (h) is calculated using the following equivalent ratios
[tex]h:w =\overline{UD}:\overline{LR}[/tex]
Express as a fraction
[tex]\frac hw =\frac{\overline{UD}}{\overline{LR}}[/tex]
Make h the subject
[tex]h =\frac{\overline{UD}}{\overline{LR}} \times w[/tex]
Substitute known values
[tex]h =\frac{25\sqrt3}{100} \times 50\sqrt 3[/tex]
[tex]h =\frac{3750}{100}[/tex]
[tex]h =37.50[/tex]
Hence, the height of the shaded triangle is 37.5 units.

Find the volume of the cone. Use 3.14 for pi.
Answers
Answer:
V=37.68
Step-by-step explanation:
The formula for the volume of a cone is V=1/3πr^2h. First, plug the values in to the varibles to get V=1/3π3^2(4), since 3 is the radius and 4 is the height. Now simplify the equation.
V=1/3π3^2(4)
V=1/3π9(4)
V=1/3π36
Multiply 36 by pi, which the equation wants you to use as 3.14.
V=1/3(113.04)
Now simplify to get V=37.68.

A geometric figure is dilated by a scale factor of 1.5 with the origin as the center of dilation. Which of the following sentences best describes this dilation?
The x- and y-coordinates of every point of the figure is multiplied by 1.5.
Not here.
The y-coordinate of every point of the figure is multiplied by 1.5.
The x-coordinate of every point of the figure is multiplied by 1.5.
Answers
Answer:
Step-by-step explanation:
The x and y points are multiplied by 1.5
See the graph
Notice that if you start with (4,6) and dilate by a scale of 1.5 then the final point is (6,9)
The slope of these two points (if they were on a line should be 1.5
x2 = 6
x1 = 4
y2 = 9
y1 = 6
m = (9 - 6)/(6 - 4)
m = 3 / 2
m = 1.5 which is what it should be.
The x-coordinate of every point of the figure is multiplied by 1.5.
The scale factor is 1.5, and the center of dilation is the origin (0, 0).
When the figure is dilated by a scale factor of 1.5 with the origin as the center, it means that each point's x-coordinate and y-coordinate are separately multiplied by 1.5.
The y-coordinate of every point of the figure is multiplied by 1.5 is not correct the reason is that in this specific dilation scenario, only the x-coordinate is multiplied by 1.5, while the y-coordinate remains the same. The origin as the center of dilation means that the points move away from or towards the origin, maintaining the same vertical distance.
Therefore, the correct description is "The x-coordinate of every point of the figure is multiplied by 1.5."
