What is the original price if saidhari and she paid $75 and it was 1/4 off the price

1 answer:

4 0

Let's set the original price as x.

1/4 off the original price would be

x-1/4x=3/4x

Set it equal to 75

3/4x=75
3x=300
x=100

The original price was $100.

Hope this helps!

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.

Can some please answer this

Sonbull [250]

Answer:

B (2 violet)

Step-by-step explanation:

Let the colors be represented by their first letter. Then the balances give rise to two equation:

o +y +b +v = r +g +b

o +y +v = g +v

Subtracting the second equation from the first gives ...

(o +y +b +v) -(o +y +v) = (r +g +b) -(g +v)

b = r +b -v

Adding v-b to both sides, we have ...

b +(v -b) = r +b -v +(v -b)

v = r

Multiplying this result by 2, we can match the final balance:

2r = 2v . . . . . . . choice B

Answer:

$x=5/2, x=-3\\$

Step-by-step explanation:

$x(2x+6)=5(x+3)\\2x^2+6x=5x+15\\2x^2+6x-5x-15=0\\2x^2+x-15=0\\2x^2+6x-5x-15=0\\2x(x+3)-5(x+3)=0\\(2x-5)(x+3)=0\\2x-5=0, x+3=0\\x=5/2, x=-3\\$
