Divide the distance on the map by 2 to get the number of 8km segments there are, then multiply that by 8km for total distance.
16 cm / 2cm = 8
8 x 8km = 64km total.
Answer:
written below for problem #2
Step-by-step explanation:
a. ratio is 12:40 since they're are 12 non fiction and 40 graphic novels
b. 40:12 (same reasoning as part a)
c. 6:40 for the ratio of science fiction to graphic novel, 12:6 for the ration of non fiction to science fiction, x:6 for the ratio of the unknown amount of fiction books to the science fiction books. (x is just there as a variable so it just represents fiction books)
Answer:
Step-by-step explanation:
By Pythagoras Theorem:
![BC = \sqrt{ {73}^{2} - {55}^{2} } \\ \\ = \sqrt{2304} \\ \\ = 48 \\ \\ \tan(C) = \frac {BD}{BC} \\ \\ \tan(C) = \frac {55}{48} \\ \\](https://tex.z-dn.net/?f=BC%20%3D%20%20%5Csqrt%7B%20%7B73%7D%5E%7B2%7D%20-%20%20%7B55%7D%5E%7B2%7D%20%20%7D%20%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%5Csqrt%7B2304%7D%20%20%5C%5C%20%20%5C%5C%20%20%3D%20%2048%20%5C%5C%20%20%5C%5C%20%5Ctan%28C%29%20%3D%20%5Cfrac%20%7BBD%7D%7BBC%7D%20%20%20%5C%5C%20%20%5C%5C%20%20%5Ctan%28C%29%20%3D%20%5Cfrac%20%7B55%7D%7B48%7D%20%20%20%5C%5C%20%20%5C%5C%20)
I think the answer is x+y/2
Y—cos 4. 4.0 hope this helps
