If a fair 6 sided cube is rolled 60 times, theoretically how many times should you expect to roll a 4 or a 5?

One of the same side angles of two parallel lines is 20° smaller than the other one. find the measures of these two angles.

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6
