Answer:
B.
E.
Step-by-step explanation:
The trigonometric functions are applied when given a side and one of the angles of a right angled triangle.
Sine θ =
Cosine θ =
Tangent θ =
Given that; hypotenuse = 9.8, opposite side = 7.5 and adjacent side = 6.3.
Then,
Sin θ =
⇒ θ =
Also,
Cos θ =
⇒ θ =
So, the appropriate answers to the given questions are options B and E.
Answer:
1/20
Step-by-step explanation:
So, he eats 5/8 of 1/3 of the pizza. That would be 5/8*1/3=5/24
Then, he eats 2/5 of what is left. What is left is 3/8*1/3=1/8.
So, 1/8*2/5=1/20
Therefore, Teddy ate 1/20 of the original pizza
Answer:
3.08$
Step-by-step explanation:
43.99 x 7% (0.07) = 3.08
Answer:
The two friends need a total of $32.5 to rent bikes for 5 hours
Step-by-step explanation:
3.25 x 5 = 16.25
16.25 x 2 = 32.50
Remark
A kite is constructed such that AB = BC and AD = DC. AB = sqrt( (1/2)AC + 18^2) see diagram. AD = sqrt(24^2 + 32^2)
Step One
Solve for AB
1/2 AC = 24 (AC is given as 48)
18 is a given length
AB = sqrt(24^2 + 18^2) = sqrt(576 + 324) = sqrt(900) = 30
Step Two
Find the length of AD
AD = sqrt(32^2 + 24^2) = sqrt(1024 + 576) = sqrt(1600) = 40
Step Three
Find the Perimeter.
P = 2 * 30 + 2*40 = 60 + 80 = 140
P = 140 <<<<< Answer
