Answer:
$57.63
Step-by-step explanation:
For x > 3, the price in dollars Mr. Roshan will pay for x pounds of beef is ...
cost = 4.99×3 +4.49(x -3) = 3(4.99 -4.49) +4.49x
cost = 1.50 +4.49x
Then for x = 12.5 pounds, the cost is ...
cost = 1.50 +4.49×12.5 = 1.50 +56.13
cost = 57.63
Mr. Roshan will pay $57.63 for 12.5 pounds of beef.
Answer:
10
Step-by-step explanation:
distance formula = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}
(x_1, y_1) = (5, 1)
(x_2, y_2) = (-3, -5)
\sqrt{ [(-3) - (5)]^2 + [(-5) - (1)]^2 }
\sqrt{ [-8]^2 + [-6]^2 }
\sqrt{ 64 + 36 }
\sqrt{ 100 }
= 10
To find this, you have to turn them into inproper fractions. You do this by doing denominator x whole number x numerator. The equation is now 14/3 x 27/4. You have to do numerator x numerator and denominator x denominator which will lead us to an answer of 378/12 or 31 6/12 or 31 1/2
