Answer:
Assuming that Janet spent an equal amount of time on each question, he would have spent 75 seconds on each question.
Step-by-step explanation:
10 minutes = 600 seconds
600 seconds / 8 questions = 75 seconds.
Angles formed by the segment in the triangles ΔWXZ, and ΔXYZ, are equal and the given corresponding sides are proportional.
- The option that best completes the proof showing that ΔWXZ ~ ΔXYZ is; <u>16 over 12 equals 12 over 9</u>
Reasons:
The proof showing that ΔWXZ ~ ΔXYZ is presented as follows;
Segment is perpendicular to segment
∠WZX and ∠XZY are right angles by definition of perpendicular to
∠WZX in ΔWXZ = ∠XZY in ΔXYZ = 90° (definition)
Therefore;
- , which gives,
Given that two sides of ΔWXZ are proportional to two sides of ΔXYZ, and
that the included angles between the two sides, ∠WZX and ∠XZY are
congruent, the two triangles, ΔWXZ and ΔXYZ are similar by Side-Angle-
Side, SAS, similarity postulate.
The option that best completes the proof is therefore;
- which is; <u>16 over 12 equals 12 over 9</u>

Area is proportional to the square of the dimensions.
Divide the dimensions by 3, and you divide the area by 3-squared = 9.
Answer:
Step-by-step explanation:
Not sure if it wants an integer as an answer but:
Step 1 - Move the negative 3π to the right.
Step 2 - Simplify by adding together
Hope this helps!
<u>Answer:</u>
The answer is B -->
<u>How I got that:</u>
<u />
These are really easy, you're simply looking for numbers that you can factor down. Like here:
I took:
and saw that I could factor out 4 from the denominator:
and then I canceled out the common factor (4 because its on both sides):
And there ya go!
