Ms. Martens only has $10 left in cash. She bought a pizza, and really wants pizza delivered to her house. The delivery driver now charges a mandatory cash tip of $4, plus $0.50 per mile they have to drive. If ms martens lives 13 miles away from the pizza place, will she have enough money to tip the driver

No, she won't have enough. She must pay $10.50 but only has $10.00!

Step-by-step explanation:

0.5 x 13 = $6.5

6.5 + 4 = 10.5

Oh no! She can't afford the delivery cost! That's too bad :[

∡ eia and ∡ kij are congruent

step-by-step explanation:

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
