Help!! I have exam in 10 minutes
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

Quadrilateral A'B'C'D'is a rotation of quadrilateral ABCD 180° about the origin.
What is the length of A'B'?
A. 6 units
B. 7 units
C. 3 units
D. 4 units
Answer:
Answer- B, 7 units
Step-by-step explanation:
I took the quiz
A.P.E.X
The length of side A'B' is 7 units, so the correct option is B.
What is the length of A'B'?We know that the side length is invariant under rotations, that means that the equivalent sides of the preimage and the image have equal length, then:
AB = A'B'.
We can see that AB= 7, then we can conclude that the correct option is B.
A'B' = 7 units.

What is the area on this?
Area of the rectangle is length x width = 5 x 10 = 50 sq. cm
Area of the triangle is 1/2 x base x height, base = 17-10 = 7, height = 5
Area = 1/2 x 7 x 5 = 17.5 sq.cm

Answer:
0.07
Step-by-step explanation:
its gonna be sin 7/10 which is approx. 0.06569 rounded to the nearest tenth is 0.07
Answer:
So judging by the fact that this is a right triangle clearly we know that we have 90 degrees. X is less than this and doesn't seem equal to the top angle area which looks to be 50 or so degrees I believe side x is 30 or 35 degrees. Sorry if I'm wrong! -Your friend, Bill Cipher

I bought 500 pieces of candy. If 42% of the candy was eaten. How many pieces
were ate?
Answer: 210
Step-by-step explanation:
42% is equal to the fraction 42/100.
We can multiply 42/100 by 500 to find how much candy was eaten.
42/100 x 500 = 210.
Therefore, 210 pieces of candy were eaten. Hope this helps and good luck!
Answer:

What is the missing value of 5x-2y=30 (8,)
Answer:
In this equation, we can start by understanding that "x" has a value of 8, as given in the ordered pair. When multiplied by 5, this leads to "40 - 2y = 30". Next, we can subtract 40 from both sides of the equation. This leads us to a value of "-2y = -10". The next step would be to divide both sides by -2 as a way of isolating "y", which leads us to a final value of "y = 5". The final ordered pair would be (8,5).
Tia cut 4-meter 8-cenimeter wire into 10 equal pieces. Martha cut a 540-centimeter wire into 9 equal pieces. How much longer is one of Marta's wires than one of Tia's?
Answer: 19.2 cm
Step-by-step explanation:
A meter is equal to 100 centimetres so the total length of Tia's wire in centimetres is:
= 4.08 * 100
= 408 cm
She cuts this into 10 equal pieces:
= 408 / 10
= 40.8 cm
Martha cuts her 540 cm wire into 9 pieces. Each piece is:
= 540 / 9
= 60 cm each
The difference is:
= 60 - 40.8
= 19.2 cm
