12+3=15
19+3=22
15*22=330
You are adding in the frame and then using your area formula of a rectangle.
Answer:
At most 3 sandwiches i would eat at this situation
Step-by-step explanation:
Making a first sandwich has a constant value 10$ but its marginal benefit is 12$. There is a 2$ benefit exist if i eat one.
Making the second one costs 20$ but its marginal benefit is 22$. Still 2$ benefit is exist if i eat the second one also.
Making the third one costs 30$ ant its marginal benefit also 30$. There is a even situation here. Making three sandwiches still an option.
After third one marginal benefit becomes lower than marginal cost of sandwiches.
Answer: use google calculator It’s reliable
Step-by-step explanation:
You know 10 students are 100%
so that we have : 7 students are 7/10 x 100 = 70
the angel you would use in a pie chat is : 70 x 3.6 = 252
Area of a cirlce=πr²
we have two radius:2r and r
area of the cirlce₁ + area of the circle₂=80 m²
area of the circle₁=π(2r)²
area of the circle₂=πr²
Then, we can suggest this quation:
π(2r)²+πr²=80
4πr²+πr²=80
π(4r²+r²)=80
π(5r²)=80
5πr²=80
r²=80/5π
r=√(80/5π)≈2.26
radius of the largest cirlce=2r=2(2.26)=4.51
Answer: the radius of the largest circle is 4.51 m
