The triangle is reflected across a line and then rotated to form the second triangle. 2 identical triangles are shown. The triangle is rotated up and to the left 90 degrees to form the second triangle.
Answer:
its the third option
Step-by-step explanation:
the one with 2 rings on the second longest angle 2 lines on longest side one side and 1 line on the shortest side
All the described pairs of triangles that are reflected, rotated, or both, can be proven congruent by the SAS postulate because such rigid transformations preserve the congruency of sides and angles.
Explanation:To determine which pair of triangles can be proven congruent by the SAS (Side-Angle-Side) postulate, we look for two sides of a triangle and the included angle that are congruent to two sides and the included angle of another triangle. When a triangle is reflected across a line, rotated 90 degrees, or both reflected and rotated, it maintains its size and shape, thus the corresponding sides and angles remain congruent.
A reflection or rotation (including a combination of both) is a type of rigid transformation which preserves the size and shape of figures. Hence, all the given pairs of triangles can be proven congruent to the original triangle through the SAS postulate, as rigid transformations do not alter the congruity of sides and included angles.

64: (48 – 42)
Answer:
32:3
Step-by-step explanation:
64:(48-42)
Note that 64:(48-42)
Can also be written as 64/(48-42)
So let's solve (48-42) first
=6
So 64/(48-42)=64/6

Answer:
1/6
Step-by-step explanation:
6x+8= 9
Subtract 8 from both sides:
6x+8-8= 9-8
6x= 1
Divide by 6 on both sides
6/6x= 1/6
x= 1/6
Answer: x=1/6
Step-by-step explanation:
subtract the 8 from the left side to the right side to get 9-8= 1. then you will have 6x=1. divide six on both sides to get x=1/6

• 8
Giving 30 points and the brainliest
The required y coordinate of E is -8. Option A is correct.
The graph is shown, point E Is drawn on the graph so that line EF is parallel to line CD. Point E is (-4, y), and the value of y is to be determined.
What is a line?The line is a curve showing the shortest distance between 2 objects in space.
Here, the Slope of line CD = 2/5 = slope of line EF (cause both lines are parallel)
The Coordinate of point f is (6,-4)
Line EF y+4 =2/5(x-6)
The coordinate of E is (-4, y)
for x = -4
y+4=2/5(-4-6)
y+4 = 2/5(-10)
y = -2*2-4
y = -8
than coordinates of E is (-4,-8)
Thus, the required y coordinate of E is -8

What is a decimal that is equivalent to the fractior
32/100 enter the answer in the box.
Answer:0.32
Explanation:
The reason why this is the answer is because if you look at a place value chart, you could see that hundreds is the second place after the decimal point so you would put the numerator right after the decimal point.
A decimal that is equivalent to the fraction 32/100 is 0.32.
How can we convert a fraction to a decimal?We can convert a fraction to a decimal by dividing the numerator by the denominator. For example, to convert 32/100 to a decimal, we divide 32 by 100, which gives us 0.32.
To convert a fraction to a decimal, we divide the numerator (top number) by the denominator (bottom number).
In this case, we want to convert 32/100 to a decimal. Dividing 32 by 100 gives us 0.32 as the decimal equivalent of the fraction.
A fundamental mathematical concept is the ability to transform a fraction to a decimal. In a fraction, the denominator denotes the total number of parts in the whole, whereas the numerator denotes the number of pieces. Divide the numerator by the denominator to convert a fraction to a decimal. To obtain the decimal equivalent of 32 in this situation, we divide 32 by 100. By multiplying this decimal by 100, we can also convert it to a percentage, which gives us 32%.
Therefore, the decimal equivalent of 32/100 is 0.32.

Answer:
Width- 15.8 ft.
Length- 32 ft.
To find the dimensions of the original rectangle when given the dimensions of a new scale drawing using a scale factor of 0.15, divide the corresponding dimensions of the scale drawing by 0.15.
Explanation:The scale factor of 0.15 means that the new dimensions in the scale drawing are 0.15 times the original dimensions. To find the dimensions of the original rectangle, divide the corresponding dimensions of the scale drawing by 0.15.
Let's say the width and length of the new scale drawing are 10 units and 15 units, respectively. To find the original width and length, divide 10 by 0.15 and 15 by 0.15.
The original width would be 66.67 units (10 / 0.15) and the original length would be 100 units (15 / 0.15).

B.)L+W = 2
LW = 126
C.)L=2W
21+ 2W = 126
D.)W = 2L
L+ 2W = 126

Choose the equations L = 2W and 2L + 2W = 126 to determine the length and width of the rectangle accurately that is option C is the correct answer
Explanation:
The correct system of equations to determine the length, L, and the width, W, of the rectangle is:
L = 2W
2L + 2W = 126
This system reflects the relationship between the length and the width given that the length is twice the width and the perimeter is 126 centimeters.

14. It costs a pool cover manufacturer $0.15 per square foot for the material they use to make pool covers. If a certain circular pool requires a cover with a 24-foot diameter, find the cost for the material
The area of the pool cover is calculated using the formula for the area of a circle, πr². After finding the area, it is multiplied by the cost per square foot to find the total cost of the material, which is approximately $67.86.
Explanation:To calculate the cost of material required to cover a pool, we first need to calculate the area of the pool cover. Since the pool is circular and has a diameter of 24 feet, the radius would be half of the diameter, which is 12 feet. The formula to calculate the area of a circle is πr², so the area of the pool cover would be π*12² which equals approximately 452.39 square feet.
Next, knowing that the cost of the material per square foot is $0.15,we multiply the area by the cost per square foot, 452.39*.15 would give us approximately $67.86. Therefore, the cost of the material for the pool cover is about $67.86.

At the park, there is a triangular sandbox with base = 12ft and height = 4ft. A drawing of the sandbox is shown above. Brie wants to make another, similar sandbox at home with base=8ft.
Your question is not clear, but it looks as though you want to know how Brie can make a similar sandbox with base = 8ft.
Answer:
For Brie to make a similar sandbox, he must use a base = 8ft, and height = (8/3)ft
Step-by-step explanation:
It is possible for Brie to make a similar triangular sandbox with base = 12ft and height = 4ft.
All he must ensure is that the ratio of base to height of the original sandbox is the same ratio of base to height of the one he is trying to make.
The original sandbox is 12:4
Because he wants to use a base = 8ft, the sandbox he is trying to make is 8:x
Where x is the height of the sandbox he is trying to make.
Then for these sandboxes to be similar, the ratio 12:4 = 8:x
=> 12/4 = 8/x
12x = 8 × 4
12x = 32
x = 8/3
The height must be (8/3)ft
A stick 1 meter long casts a shadow 1.2 meters long. A building casts a shadow 17 meters long. How tall is the building (to 2 decimal places)
Answer:
14.17m
Step-by-step explanation:
1 / 1.2 = x / 17
x = 17 / 1.2 = 14.1666667 -> 14.17m
14.17m tall is the building (to 2 decimal places).
What is after the decimal point?Digits after the decimal point. The position of the digit to the right of the decimal point of the number is written in decimal notation. For example, 0.079 has 0 decimal places, 7 decimal places, and 9 decimal places.
Rounding a decimal number to two decimal places is the same as rounding to one-hundredth of the second decimal place. For example, 2.83620364 can be rounded from 2.84 to two decimal places, and 0.7035 can be rounded from 0.70 to two decimal places.
1 / 1.2 = x / 17
x = 17 / 1.2 = 14.1666667 -> 14.17m
