Answer:
b
Step-by-step explanation:
In a 30-60-90 right triangle, the hypotenuse is twice the length of the short leg.
The hypotenuse is AB and is 18.
The short leg is BC and is 9.
The only choice with BC = 9 is b.
Answer: b
Answer: SECOND OPTION.
Step-by-step explanation:
For this exercise it is important to remember "Rigid transformations".
Rigid transformations are those transformation that preserves length. These are the following:
- Reflection.
- Tanslation.
- Rotation.
According to the information given in the exercise, the triangle JKL was translated 12 units vertically and then reflected over the y-axis to create triangle J'K'L'. Therefore, JKL and J'K'L' are congruent.
Knowing the above, you can set up the following equation:

The final step is to solve for "x" in order to find its value. You get that this is:

24 / 30 x 100 = 80
answer: <span>Twenty-four is 30% of 80</span>
Hello there! I can help you! We are loooking for the value of x in this problem. We will solve for it by adding 4 1/6 to both sides of the equation, because a negative number plus a positive number cancels out. -4 1/6 + 4 1/6 cancels out. 9 1/3 (9 2/6) + 4 1/6 is 13 3/6 or 13 ½ in simplest form. x doesn't need to be divided, so we are finished. There. x = 13 ½. The answer is C.
Answer:
Maria sells 27 pancake dishes every two hours in her restaurant. The equation that best represents p= 27/2 h and constant of proportionality is 27, and it means that she sells 13.5 pancakes an hour. :)
