Answer:
In one hour, he can code 4/5, 80%, of the game.
Step-by-step explanation:
If he can code 3/5 of his game in 3/4 hour, 60% in 45 minutes, he can code 20% every 15 minutes.
The area of a trapezium is
A = (a<span>+</span><span>b)*h</span><span>/2
24 + 18 = 46 * 5 = 230 / 2 = 115</span>
Answer:
1.85 grams
Step-by-step explanation:
1 milligram is equal to 0.01 gram
so 1850 should be equal to 1.85 grams
X²-y²=5
converting the above into polar form we shall have:
x=r cosθ; y=r sinθ
thus
x²-y²=5 will be written as:
(r cosθ)²-(r sinθ)²=5
r² cos²θ- r² sin²θ=5
factoring r² out we get:
r²(cos²θ- sin²θ)=5
using trigonometric identity:
cos²θ- sin²θ=cos(2θ)
thus the expression will be:
r²(cos (2θ))=5
r²=5/cos (2θ)
hence;
r=√[5/cos (2θ)]
