Hello from MrBillDoesMath!

Answer:

(3b -a) / ( 1 + b^2)

Discussion:

My best guess is that we are trying to simply this fraction:

( 3 - a/b) / ( (1/b) + b)   =             => multiply num. and denom. by "b"

(3b - a) / (   (1/b)*b + b*b) =

(3b -a) / ( 1 + b^2)


Thank you,

MrB

Identify the number that cannot be written as a power with an exponent greater than 1.
Viefleur [7K]
4 = 2² (2×2)
9 = 3² (3×3)
16 = 4² (4×4)

50, however, can't be written with a power like ² or ³.
It falls between 7² (49) and 8² (64).
It falls between 3³ (27) and 4³ (64)...etc.

Trapezoid PQRS is rotated 180° about the origin to form trapezoid P'Q'R'S'. Which statement is true?
Vikki [24]

Answer: D)The angle measures of trapezoid PQRS are equal to the corresponding angle measures of trapezoid P'Q'R'S'

Step-by-step explanation:

Since, By the definition of rotation about origin, When a figure is rotate 180° about the origin then we get a congruent figure to that figure.

Thus, when PQRS is rotated 180° about the origin to form trapezoid P'Q'R'S'.

Then trapezoid P'Q'R'S' is congruent to trapezoid PQRS.

⇒  By the definition of congruence,

The corresponding sides and angle of trapezoid P'Q'R'S' are congruent to that of trapezoid PQRS.

⇒ ∠P' ≅ ∠P, ∠Q' ≅ ∠Q, ∠R' ≅ ∠R and  ∠S' ≅ ∠S

⇒ Option D) is correct.

Note:  P'Q'R'S' is a trapezoid ⇒ Sum of the angle measures of trapezoid P'Q'R'S' is also 180°

Option A) is incorrect.

Since, trapezoid P'Q'R'S' is congruent to trapezoid PQRS.

⇒ Option B) is incorrect.

We know that if two shapes are congruent then their area must be equal.

⇒ Area of trapezoid P'Q'R'S' = Area of trapezoid PQRS

Thus, Option C) is also incorrect.

the area of a rectangular park is 7/8 sqaure mile. the length of the park is 3/4 mile. what is the width of the park?
kondaur [170]

Answer:

7/6

Step-by-step explanation:

since the formula of area is length times width,you have to divide the area by the length to find the width

area=length×width

the width will be

width=area÷length

=7/8÷3/4

7/8×4/3

7/2×1/3

7/6

that's the width you can prove it by multiplying the length times the width to see if you will get 7/8..

I hope this helps
