Answer:
It depends on the person, I personally work better plugging in numbers and practicing with numbers I like. I say just try different ways and see what works best for you.
Answer:
3.25 +7.25m
Step-by-step explanation:
The cost of membership in Jump Rope Gym can be modeled by ...
total cost = initial fee + m × (monthly fee)
j = 6.50 +17.50m
Likewise, the cost for Run Run Run Gym is ...
r = 9.75 +24.75m
Then the savings by joining the Jump Rope Gym is ...
r -j = (9.75 +24.75m) -(6.50 +17.50m) = 3.25 -7.25m . . . .savings
Answer:
<u>Story</u>
Jane is 1.7 m tall. She stands 250 m away from the base of the Eiffel tower and looks up at the top of the building. The angle of elevation from her eyeline to the top of the building is 45°.
<u>Question</u>
Calculate an estimate of the height of the building. Give your answer to the nearest meter.
<u>Calculation</u>
Label the sides of the triangle O, A and H (where O is the side opposite to the angle, A is the side adjacent to the angle and H is the hypotenuse).
In the triangle, the angle and side A is known, and O must be calculated.
Therefore, use the trig ratio tan(x) = O/A:
⇒ tan(40) = O/250
⇒ 250tan(40) = O
⇒ O = 209.7749078...
Assume Jane's eye-level is approximately 1.5 m above the ground.
Therefore, the Eiffel tower is approximately:
209.7749078... + 1.5 = 211.2749078.. meters tall
Rounding to the nearest meter ⇒ 211 m
the answer is 60 :) good luckStep-by-step explanation:
