91 is your composite number
Everything else is prime.
Answer:
Position of the submarine now relative to the water surface ![=-47\ \frac{3}{4}](https://tex.z-dn.net/?f=%3D-47%5C%20%5Cfrac%7B3%7D%7B4%7D)
Step-by-step explanation:
It says that the position of a submarine relative to the water surface was -32 1/4 feet . A downward navigational maneuver increased it's depth by 15 1/2 feet.
Now we need to find about what is the position of the submarine now relative to the water surface.
Downward navigation means we 15 1/2 is negative
so we will just add both values to get the final answer:
Position of the submarine now relative to the water surface = ![-32\ \frac{1}{4}-15\ \frac{1}{2}](https://tex.z-dn.net/?f=-32%5C%20%5Cfrac%7B1%7D%7B4%7D-15%5C%20%5Cfrac%7B1%7D%7B2%7D)
![=-32\ \frac{1}{4}-15\ \frac{2}{4}](https://tex.z-dn.net/?f=%3D-32%5C%20%5Cfrac%7B1%7D%7B4%7D-15%5C%20%5Cfrac%7B2%7D%7B4%7D)
![=-47\ \frac{3}{4}](https://tex.z-dn.net/?f=%3D-47%5C%20%5Cfrac%7B3%7D%7B4%7D)
Answer:
a) 10x + 8 = 21
b) x = 1.3
Step-by-step explanation:
The line of symmetry is a vertical line that passes through point C.
That makes sides BC and CD congruent, and sides AB and ED congruent.
perimeter = AB + BC + CD + DE + EA
perimeter = 2x + 3 + x + 1 + x + 1 + 2x + 3 + 4x = 10x + 8
perimeter = 21
a) Equation:
10x + 8 = 21
b)
10x + 8 = 21
10x = 13
x = 1.3
Step-by-step explanation:
1600km / (400km/h) = 4 hours.
4 hours after 9:45p.m. => 1:45a.m.
Hence it will reach Singapore at 1:45a.m. the next day. (assuming same time zones)
