Answer:

C'Q = QC ; ⊥ A'A ; A'A || B'B ; m∠TRB = 90°

Step-by-step explanation:

Each pre-image point is the same distance from the line of reflection as the image point. Therefore C'Q = QC.

Lines of reflection are perpendicular to pre-image and image points; this makes the third statement true.

Lines connecting pre-image points to image points are parallel; thus A'A || B'B.

Since lines of reflection are perpendicular to pre-image and image points, the sixth statement is true.

isabel thinks she has space for a 45 inch wide book case it turns out she only has space for a 40 inch wide book case what is th

Minchanka [31]

Answer:

The percent error in Isabel's measurement is 12.5%.

Step-by-step explanation:

Given:

Isabel thinks she has space for a 45 inch wide bookcase it turns out she only has space for a 40 inch wide bookcase.

Now, to find the percent error in Isabel's measurement.

Measurement she thinks = 45 inch.

The actual measurement = 40 inch.

So, the error in measurement = $45-40=5\ inch.$

Now, to get the percent error of the measurement:

$\frac{5}{40} \times 100$

$=\frac{500}{40}$

$=12.5\%.$

Therefore, the percent error in Isabel's measurement is 12.5%.

The quotient of a number x and −1.5 is 21

Andru [333]

Answer:

x = -31.5

Explanation:

We are given that the quotient of x and -1.5 is 21

This means that:

$\frac{x}{-1.5} =21$

To get the value of x, we will multiply both sides of the equation by -1.5

This means that:

$\frac{x}{-1.5} * -1.5=21*-1.5$

x = -31.5

Note that the value of x must be negative because we are dividing by a negative number and the quotient is positive (-ve/-ve is +ve and +ve/-ve is -ve)

Hope this helps :)
