Answer with explanation:

The Meaning of the term Reflection Symmetry is that, the line which divides the geometrical shape into two congruent Parts.

First one is Isosceles Triangle, Second one is Trapezoid, Third one is Closed shape , fourth one appears Scalene Triangle.

There is no line in a trapezoid through which the two parts appear congruent to each other, neither that line can be found in closed curve nor in Scalene triangle.

But , if you draw a line through that vertex of Isosceles triangle where two equal congruent Sides intersect, then that line will be Reflection symmetry of line.

Option A

Bruce has a rope that is 21 feet long he needs to cut the rope into 1/5 long peices. How many strips can Bruce cut from his rope
dybincka [34]

Bruce has a rope that is 21 feet long he needs to cut the rope into 1/5 long pieces.

The length of the rope = 21 feet

the length of each strip = \frac{1}{5}

We need to cut the rope 21 feet into \frac{1}{5} strips

To find the number of strips we divide 21 feet by the length of the strip

\frac{21}{\frac{1}{5}} = 21 * \frac{5}{1} = 105

105 strips can Bruce cut from his rope.

Answer:

12.6

Step-by-step explanation:

To find the area of a cylinder, you find the area of the circular base and multiply it by the height. Remember that the area of a circle is pi*r^2. R, the radius, is 2. Putting this into a calculator and rounding to the nearest tenth, you get 12.6. Now that we have the circle, we multiply by the height. Since the height is 1, we have our answer of 12.6.

Mark and Trisha are traveling in the same direction and Mark is going 16 miles per hour. Trisha is going 12 miles per hour but s
Lorico [155]

Answer:

32 miles

Step-by-step explanation:

Given data

Let the total distance be x miles

Marks speed= 16miles per hour

Trisha's speed= 12 miles per hour

Trisha has covered 8 miles and has  (x-8) miles to finish line

We know that

Speed= distance/time

time= distance/speed

Hence the time taken for Mark to finish is

time= x/16---------------1

The time taken for Trisha to finish is

time= (x-8)/12-----------2

equate 1 and 2 above

x/16= (x-8)/12

cross multiply

16(x-8)= 12*x

16x-128= 12x

collect like terms

16x-12x= 128

4x=128

x= 128/4

x= 32 miles

Hence they will meet at exactly 32 miles along the way
