Shannon exercise for 0.75 hour on Monday wednesday and Friday each week. How many hours will she exercise in 4 weeks

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

answer:

c) the x-coordinate of the center of the circle increases by 3

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
