<h3>
Answer: There is only one answer and it is choice B</h3><h3>Angle 1 and angle 4 are alternate interior angles</h3>
========================================================
Explanation
- A. This is false because it should be angle 4 + angle 5 = 180 without the angle 6. Adding on angle 6 results in some angle larger than 180. Note how angle 5 = (angle 3)+(angle 6).
- B. This is true and useful to showing that the three angles of a triangle add to 180 degrees. This is because you'll use the fact that angles 4, 5 and 6 combine to 180 degrees.
- C. While this is a true statement by the exterior angle theorem, it is not useful to the proof. It is better to state that angle 2 and angle 6 are congruent because they are alternate interior angles.
- D. Like choice C, it is true but not useful. It's better to say that angle 1 is congruent to angle 4. See choice B above.
Note how it's not enough for a statement to be true. It also needs to be relevant or useful to the context at hand. A more simpler example of this could be stating that x+x = 2x.
Answer:
Therefore Josie drove 57.5 miles.
Step-by-step explanation:
Speed: The ratio of distance to time.
To find the distance we use the following formula
![Distance= time \times speed](https://tex.z-dn.net/?f=Distance%3D%20time%20%5Ctimes%20speed)
Given that Josie drove 45 minutes at 70 miles per hour.
![45 \ minutes= \frac{45}{60}\ h=\frac34\ h](https://tex.z-dn.net/?f=45%20%5C%20minutes%3D%20%5Cfrac%7B45%7D%7B60%7D%5C%20h%3D%5Cfrac34%5C%20h)
In 45 minutes, she traveled = ![(70\times \frac34) \ miles](https://tex.z-dn.net/?f=%2870%5Ctimes%20%5Cfrac34%29%20%5C%20miles)
=52.5 miles.
The she drove 15 minutes at 20 mile per hour.
![15 \ minutes= \frac{15}{60}\ h=\frac14\ h](https://tex.z-dn.net/?f=15%20%5C%20minutes%3D%20%5Cfrac%7B15%7D%7B60%7D%5C%20h%3D%5Cfrac14%5C%20h)
In 15 minutes, she traveled ![=(20\times \frac 14) \ miles](https://tex.z-dn.net/?f=%3D%2820%5Ctimes%20%5Cfrac%2014%29%20%5C%20miles)
=5 miles
Therefore Josie drove (52.5+5) miles= 57.5 miles.
Answer:
8m.
Step-by-step explanation:
an = 2 an-1 means that each term in the sequence( except the first) is obtained by multiplying the last term by 2, so the first 4 terms are m, 2m, 4m, 8m.
Now get the square root of 30
Answer:
6
Step-by-step explanation:
4n - 12 < 2n + 2 is for n=6
4×6 -12 < 2×6 +2
24 - 12 < 12 + 2
12 < 14 correct
for n=7
4×7 - 12 < 2×7 + 2
16 < 16 incorrect
for n=8
4×8 - 12 < 2×8 + 2
20 < 18 incorrect
for n=9
4×9 - 12 < 2×9 + 2
24 < 20 incorrect
so, only for n=6 is the expression true.
