Arunner ran at a rate of 0.12 mile per minute for 50 minutes on monday, wednesday ,and friday. on saturday and tuesday the runner ran 0.14 mile per minute for 60 minutes and on sunday the runner ran 0.08 mile per minute for 1 hour 30 minutes. what was the total mileage the runner covered during the week

42 miles

Step-by-step explanation: For Monday, Wednesday, and Friday you would multiply 0.12, 50, and 3, and get 18 miles.

For Saturday and Tuesday multiply 0.14, 60, and 2 and get 16.8

For Sunday, multiply 0.08 and 90 and get 7.2 then add your answers together to get 42

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
