lilavasa [31]
Use the Pythagorean theorem:

\left(\dfrac{1}{2}x\right)^2+12^2=18^2\\\\\dfrac{1}{4}x^2+144=324\ \ \ |-144\\\\\dfrac{1}{4}x^2=180\ \ \ \ |\cdot4\\\\x^2=720\to x=\sqrt{720}\\\\\boxed{x\approx26.8}

3/4 of a number minus -16 equals 28. What is the number ?
Zigmanuir [339]

Answer:

The number is 16

Step-by-step explanation:

3/4 n- (-16) = 28

3/4 n + 16 = 28

Subtract 16 from each side

3/4 n +16-16 = 28-16

3/4 n =12

Multiply by 4/3 to isolate n

4/3 * 3/4 n = 12 * 4/3

n = 16

Figure ABCD is transformed to figure A prime B prime C prime D prime, as shown below: A coordinate grid is shown from negative 5
defon

The transformed figure has the opposite orientation (A'B'C'D' is counterclockwise, whereas ABCD is clockwise), so a reflection is involved. The sgment C'D' is still at the bottom, as is CD, so the reflection must be across a vertical line.


In the attached, the light-blue figure A''B''C''D'' shows the reflection of ABCD across the y-axis. It is easy to see that figure A'B'C'D' is a translation of that 5 units downward.


The appropriate choice is the 2nd one ...

... Reflection over the y-axis followed by a translation down by 5 units.
