Answer:
Option C is correct.
Ratio of longer leg to hypotenuse is; 
Step-by-step explanation:
This is the special right angle triangle 30°-60°-90° as shown below in the figure.
- The side opposite the 30° angle is always the shortest because 30 degrees is the smallest angle.
- The side opposite the 60° angle will be the longer leg, because 60 degrees is the mid-sized degree angle in this triangle.
- Finally , the side opposite the 90° angle will always be the largest side(Hypotenuse) because 90 degrees is the largest angle.
In 30°−60°−90° right triangle,
- the length of the hypotenuse is twice the length of the shorter leg,also
- the length of the longer leg is
times the length of the shorter leg.
Then:
the sides are in proportion i.e, 
Therefore, the ratio of the length of the longer leg to the length of its hypotenuse is: 
Answer:
1405.8 pence fare
Step-by-step explanation:
First we have to change meters into km by dividing the distance by 1000
here we have:
Fare: 9 pence
Distance: 100m/1000 = 0.1 km
when it was
0.1 km -----------> 9 pence fare
if 1 km ------------> 9/0.1 fare
if 15.62 ------------> 9*15.62/0.1
15.62 km ----------> 1405.8 pence fare.
The equation would be y=2.10x+3.25!
Also know as A lol
If you plug in 9 as x and add 3.25 it is an easy way to check the answers for further questions!
Have a good day! :-)

Answer: The answer is 
Step-by-step explanation: Given that a glass bottle is filled with oil weighs 590 grams. After that, Sophia uses 200 millilitres of oil and then the bottle weighs 400 grams.
Therefore, the weight of the oil that Sophia uses = 590 - 400 = 190 grams.
That is, 190 grams = 200 millilitres, so

So, the relation between the weight 'M' of the bottle of oil, in grams, is a function of 'V', the volume of oil Sophia used is given by

F(x)=1-x² and g(x)=√(11-4x)
(g+f)(2)=>
1-(2)²+√(11-4(2))
=√3-3
(f/g)(-1)
(1-(-1)²)/(√(11-4(-1))
=0
(g-f)(-1)
√(11-4*-1)-(1-(-1)²
=√15
(g×f)(2)
1-(2)²×√(11-4(2))
-3√3
