C = π d
C = (22/7) × (35/2) = (22/2)(35/7) = 11(5) =55
Answer: 55, second choice
Answer:
80.5 km/h
Step-by-step explanation:
divide the 426.65 by 5.3 hours to get 80.5/1 hr
The relationship that their ratios of sin x and cos y share is that they are of equal ratio: sin x = cos y = 4/5
<h3>Recall the Trigonometry Ratios</h3>
- SOH represents sin ∅ = opposite/hypotenuse
- CAH represents cos ∅ = adjacent/hypotenuse
- TOA represents tan ∅ = opposite/adjacent
Thus, given the right triangle as shown in the picture attached below, let's find sin x and cos y.
sin x = opp/hyp = 4/5
cos y = adj/hyp = 4/5
This implies that sin x = cos y, therefore the relationship that their ratios of sin x and cos y share is that they are of equal ratio: sin x = cos y = 4/5

Answer:
1 apple costs $1.2
1 pear costs $1
Step-by-step explanation:
Represent Apples with A and Pears with P
For the person in my front, the expression is:
For me, the expression is
Hence, the system of equation is:
Solving for the values of A and P.
Substract equation (2) from (1)
<em>Hence, 1 pear costs $1</em>
Substitute 1 for P in
<em>Hence, 1 apple costs $1.2</em>
