So, teh exact value is sqrt( 19^2 - 8^2 ) = sqrt( 361-64) = sqrt(297).
There's people who can calculate this mentally, but I can't. Approximate by known squares: 15^2 = 225, 16^2 = 256, 17^2= 289, 18^2=324,
So, 18.
Answer: -6
Step-by-step explanation:u can do keep change switch which u do the expression to -12+(-3)+9
The inverse always makes negates the original hypothesis and conclusion, so I'd say it's false
Answer:
Step-by-step explanation:
we are given that selling price of each mug(x) is $10
Selling price of each shirt(y) is $20.
Jake wants to earn atleast $250 for his team, So we can write
(2) Now the above inequality can be solved for y as follows:
(3)
By the observing the above equation that we just solved for y, we can say that It has an y-intercept of 12.5, and a negative slope of 0.5. Y-intercept of 12.5 means, jake must sell atleast 13 shirts to achieve the target.
