Help!! I have exam in 10 minutes

Natalka [10]

Answer:

LHS=(1-sin60)/cos60

=(1-√3÷2)/1÷2

=2(1-√3÷2)

=2-√3

RHS=(1-tan30)/(1+tan30)

={1-(1÷√3)}/{1+(1÷√3)}

={(√3-1)/√3}/{(√3+1)/√3}

=(√3-1)/(√3+1)

={(√3-1)(√3-1)}/{(√3+1)(√3-1)}

=(3-√3-√3+1)/(3-1)

=(4-2√3)/2

=2-√3

If 34 percent of 60 million barrels is gasoline and 29 percent of 60 million barrels is desil how many more barrels are there of

Andre45 [30]

The difference between 34 percent and 29 percent is :

34 - 29 = 5 percent.

60 million times 5% = 60 x 0.05 = 3 million

to check:

60 million x 34% = 20,400,000 barrels

60 million x 29% = 17,400,000 barrels

20,400,000 - 17, 400,000 = 3,000,000 barrels

There are 3 million more barrels of gasoline.

25 points to anybody who can solve this pls!

Svetach [21]

Answer:

Q' (2,4)

R' (3,1)

S' (5,3)

Step-by-step explanation:

When reflected across x-axis, the x-values stay the same but y-values change signs. Because you count how many points till the reflection line then same amount you have to go to the other side. But since it is saying x-axis, the reflection line is on x=0 so you just change the sign.

Why is it that the orthocenter of an obtuse triangle must lie on the outside of the triangle?

Taya2010 [7]

It is important to understand the meaning of orthocenter in respect to a triangle first. Ii is actually the intersection of all the altitudes within a triangle. The altitudes can be drawn from an angle to the opposite side but the line should create a right angle with the side of the triangle. In case of obtuse triangle, the three lines would meet outside the triangle. I hope the answer helps.
