6x3.14 = 18.84. That should be the answer
To answer this we need to divide 12,000 by 10 and our answer will be the tenth of 12,000. Then we will check our work. Lets do it:-
12,000 ÷ 10 = 1,200
1,200 is the tenth of 12,000.
CHECK OUR WORK:-
1,200 × 10 = 12,000
We were RIGHT!!
So, 1,200 is the tenth of 12,000.
Hope I helped ya!!
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
Answer: Multiply
Step-by-step explanation:
Answer:
Dependent Variable: Height of bounce
Independent Variable: Type of ball
Step-by-step explanation:
Dependent variable is what is being tested while the independent variable is what changes in the experiment or what causes the dependent variable results to change.
