<span>The problem is tricky because it actually gives you the diameter, not the radius. To get the radius, we need to divide 34 by 2 to get 17. Then we proceed as you did to get V = 24,501.42 m^3. Also notice that because we are working with volume, we have cubic meters, not square meters. Other than that, your answer was perfect!</span>
Answer:
A) 53
B) 53%
C) 37%
D) 63%
E) Yes.
Step-by-step explanation:
A) 53 people did not get headaches at all.
B) To solve for the percentage of participants that reported they did not get a migraine headache, you will need to divide out of the TOTAL number of people:
53/100= .53 --> Convert to percentage--> .53×100 = 53%.
C) To find this value, you will need to divide out of the amount of people that took MEDICINE and got a headache:
22/60≈0.367--> Convert to percentage --> 0.367×100≈37%
D) This percentage will be found out of who did NOT take the medicine:
25/40= 0.625 --> Convert to percentage --> 0.625×100≈63%
E) The medicine did help prevent migraine headaches because the percentage that got <u>migraines with the medicine is lower</u> than the percentage that got <u>migraines WITHOUT the medicine.</u>
Answer:
sin(72°)=x÷20ft.
sin(72°)×20ft.= 19ft 252 inches
the ladder reach 19ft 252 inches tall on the building.
Step-by-step explanation:
Answer:
The height of the tower is 94 ft
Step-by-step explanation:
In a given right angle triangle we will use <em>''sohcahtoa"</em><em>.</em>
tan (60°) = opp/adj
tan (60°) = x/50
√3 = x/50
x = 50√3
x = 50 × 1.732
x = 86.6
Now, The height of the tower is (x + 7)
86.6 + 7 = 93.6 ≈ 94
Thus, The height of the tower is 94 ft
