Answer:

Base of figure A = 12 units

Step-by-step explanation:

Given:

Base of figure B = 15 units

Ratio of figure A to figure B = 4:5

Find:

Value of X

Computation:

X / 15 = 4 / 5

x = 4(15) / 5

x = 12

Base of figure A = 12 units

Which transformation will map an isosceles trapezoid onto itself? rotation by 180° about its center, reflection across a diagona
alukav5142 [94]

Answer:

The correct option is 4.

Step-by-step explanation:

The non parallel sides of an isosceles trapezoid are congruent.

The image of an isosceles trapezoid is same as the preimage of isosceles trapezoid if

1. Reflection across a line joining the midpoints of parallel sides.

2. Rotation by 360° about its center.

3. Rotation by 360° about origin.

If we rotate the trapezoid by 180° about its center, then the parallel sides will interchanged.

If we reflect the trapezoid across a diagonal, then the resultant figure will be a parallelogram.

If we reflect across a line joining the midpoints of the nonparallel sides, then the parallel sides will interchanged.

After rotation by 360° about the center, we always get an onto figure.

Therefore option 4 is correct.

Stanley, the skunk, is traveling from point A to point B by taking a shortcut through the pond.A path that avoids the pond is 25
san4es73 [151]
Stanley the skunk will save about 15.5 feet.

This problem can be solve with the Pythagorean Theorem. The possible paths that Stanley can take make a right triangle. The legs of the triangle are 25 and 28, and the hypotenuse would be 37.5.

If Stanley went the long way, he would travel 25 + 28 = 53 feet. Taking the short way (hypotenuse) is 53 - 37.5 = 15.5 feet shorter.

PLEASE HELP ASAP FOR BRAINLIEST<br><br> Solve the following one step equation.<br><br> -6 = b/18
FromTheMoon [43]
Answer is -1/3

you would divide both sides by 18 to get the variable on its own and that would leave you with -6/18 and so you have to simplify it by dividing the numerator and denominator by the greatest common factor (6) to get your remaining simplified fraction of -1/3
