Practice question — Given the trapezoid to the right find the length of legs in the following isosceles trapezoid
Answers
Given:
A figure of an isosceles trapezoid with bases 18 and 24, and the vertical height is 4.
To find:
The legs of the isosceles trapezoid.
Solution:
Draw another perpendicular and name the vertices as shown in the below figure.
From the figure it is clear that the AEFD is a rectangle. So,
[tex]EF=AD=18[/tex]
Since ABCD is an isosceles trapezoid, therefore in triangle ABE and DCF,
[tex]AB=DC[/tex] (Legs of isosceles trapezoid)
[tex]AE=DF[/tex] (Vertical height of isosceles trapezoid)
[tex]m\angle AEB=m\angle DFC[/tex] (Right angle)
[tex]\Delta ABE\cong \Delta DCF[/tex] (HL postulate)
[tex]BE=CF[/tex] (CPCTC)
Now,
[tex]BE+EF+FC=BC[/tex]
[tex]2BE+18=24[/tex]
[tex]2BE=24-18[/tex]
[tex]2BE=6[/tex]
[tex]BE=3[/tex]
Using Pythagoras theorem in triangle ABE, we get
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
[tex](AB)^2=(AE)^2+(BE)^2[/tex]
[tex](AB)^2=(4)^2+(3)^2[/tex]
[tex](AB)^2=16+9[/tex]
[tex](AB)^2=25[/tex]
Taking square root on both sides, we get
[tex]AB=\pm \sqrt{25}[/tex]
[tex]AB=\pm 5[/tex]
Side length cannot be negative. So, [tex]AB=5[/tex].
Therefore, the length of legs in the given isosceles trapezoid is 5 units.

Nancy has to find the reflection of a point across both the x- and the y-axes. Using what you've learned so far about reflections across the x-axis and reflections across the y-axis, can you come up with a rule for what happens to the signs when you reflect a point across both axes?
Answers
Answer:
Step-by-step explanation:
All she needs to know is that a reflection across the x-axis is when the x coordinate stays the same and the y-coordinates change.
Hope this helped.
Answer:
To find the reflection of a point across the x-axis and the y-axis, change the signs of both the x-coordinate and the y-coordinate.

if john wallked 50 miles than mira,how many miles do you think mira walked if they both walked a total of 290 miles.
Answers
Answer:
Mira = 95 miles
Step-by-step explanation:
Given
John walked 50 miles than Mira
The total miles walked is 290
To find
If John walked 50 miles more than Mira and the total miles walked including Mira is 290, then divide 290 by both of them. Once that is done, don't evenly distribute the miles to them. Because remember, John walked 50 miles more than Mira. So we just distribute this with John having 50 miles more. By subtracting 50 from Mira's share and give it to John
Solve
Divide 290 by 2290 ÷ 2 = 145
Subtract 50 from Mira's share and give it to JohnMira's 145 - 50 = 95
Add that 50 to John's 145John's 145 + 50 = 195
Therefore, John ran 195 miles and Mira ran 95 miles.

Sonia walks to her aunt's house. She leaves home at 1025. She walks a total of 12km at an average speed of 5km/h. Work out the time Sonia arrives at her aunt's house.
Answers
Answer: 1249 hrs
Step-by-step explanation:
Sophia walked for 12 km to get to her aunt's house.
She did this at a speed of 5km/h which means that the time taken was:
Time = Distance / Speed
= 12 / 5
= 2.4 hours
2.4 in hours:
= 0.4 * 60 minutes
= 24 minutes
= 2 hours 24 minutes
If she left at 1025, she would arrive at:
= 1025 + 2 hours 24
= 1249 hrs

Rosa has rows of plants. There are plants in each row. Each plant has flowers. How many flowers are there in all?
Answers
Answer:
There will be total 855 flowers.
Step-by-step explanation:
Suppose there are 9 total rows and each row has total 19 plant and each plant has 5 flowers.
Then the number of flowers can be found out by simply multiplying
9*19*5= 855
There will be total 855 flowers (if the above given numbers assumed are the same as the original question)
IF the numbers are changed from the above assumed numbers even then the answer can be obtained by simply multiplying the numbers to get the total numbers of flowers.

Answer:
102,9 cm^2
Step-by-step explanation:
First of all we can find the area of the two rectangles at the sides of the figure
A rectangle = length x width = 8 x 4 = 32 cm^2
the rectangles are two so:
32 x 2 = 64 cm^2
for the figure in the center we can proceed like this: we can initially assume that also it is a rectangle, so we have to find the length
length = 16-8 = 8 cm
A = 8^2 = 64 cm^2 (so we have discovered that is a square)
if we look we can see that there is also a semicircle that is not part of the figure. We have to find its area and subtract it to the area of the square
A semiciricle = (radius^2 π)/2
radius = 8/2 = 4 cm
A semicirlce = (4^2) π/2 = 25,13 cm^2
64 - 25,13 = 38,87 cm^2
At least we have to added up this value to the area of the two rectangles
total area = 38,87 + 64 = 102,87 = 102,9 cm^2
