The answer is 18
I did this by first finding 9% of 100 which is of course 9 then I multiplied by 2
Answer: 2.65·10^-2
Step-by-step explanation. : 1.5·10^-3= 0.0015 and 2.5·10^-2= 0.025.
Sum is 0.0265
Answer:
32 m
Step-by-step explanation:
<u>Trigonometric ratios</u>
where:
- is the angle
- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
Calculate the height of the radio mast using the tan trig ratio.
Given:
- = 30°
- O = h (height of radio mast)
- A = 96 m
To calculate the distance from the second point to the base of the mast, use the tan trig ratio:
Given:
- = 60°
- O = 32√3 m
- A = d
Answer:
4 hours
Step-by-step explanation:
We can already assume that the freight train is 60 miles ahead of the express. If the freight is going at a constant of 30 mph and the express goes 50 mph then we can say that when the freight train has been gone for 6 and the express for 4 the express will have passed the freight. The reason as to why would be that 60 + 120 = 180 or 60 + (30 x 4) = 180 and 50 x 4 = 200 .
Sorry if that explanation doesn't make sense but I hope this helped.
Answer:
They have 2 angle measures in common, so that means the third measure has to be the same.
