(°C*1,8)+32
(25*1,8)+32 = 45+32 = 77°F
Answer:
Step-by-step explanation:
Between 9:00 am and 10:45 am, there have been 1 hour and 45 minutes or 1.75 hours have passed. Let x be the speed of the slower cyclist and x+ 5 be the rate of the second cyclist. The given situation is best represented through the equation below,
x(1.75) + (x + 5)(1.75) = 47.25 km
The value of x from the equation is 11. Thus, the two bicyclists' rates are 11 km/h and 16 km/h.
Without using the trigonometry ratio, we can find the distance between the ship and the buoy by:
the distance between City and Lemont SUBTRACT the vertical distance between City and the point parallel to the Ship
The distance between the City and Lemont can be worked out using the Sin rule
![\frac{57.8}{sin(36)}= \frac{City-Lemont}{sin(92)}](https://tex.z-dn.net/?f=%20%5Cfrac%7B57.8%7D%7Bsin%2836%29%7D%3D%20%5Cfrac%7BCity-Lemont%7D%7Bsin%2892%29%7D%20)
![City-Lemont= \frac{57.9sin(92)}{sin(36)} = 98.27.....](https://tex.z-dn.net/?f=City-Lemont%3D%20%5Cfrac%7B57.9sin%2892%29%7D%7Bsin%2836%29%7D%20%3D%2098.27.....)
≈98.3
The vertical distance between the City and the point parallel to the ship can be worked out using the Pythagoras theorem
![\sqrt{57.8^{2}- 44.6^{2} } =36.765...](https://tex.z-dn.net/?f=%20%5Csqrt%7B57.8%5E%7B2%7D-%2044.6%5E%7B2%7D%20%7D%20%3D36.765...%20)
≈36.8
The distance between the ship and the Buoy is given:
![98.3-36.8=61.5](https://tex.z-dn.net/?f=98.3-36.8%3D61.5%20)

Answer:
right triangle
Step-by-step explanation:
Notice that if you go forward, the common ratio is 5. Each new term is found by mult. the previous term by 5.
If, on the other hand, you go backwards (terms decreasing), then you divide a term to find what the previous term was.
Here, divide 1 by 5 to find the first term. It's 1/5.
