Represent each situation using a proportion. Use your proportion to write an equation and solve. Check your answer. a. What number is 40% of 90? b. What number is 45% of 90? c. 27 is 30% of what number? d. 18 is 30% of what number? e. 25.5 is what percent of 85? f. 21 is what percent of 60?

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

answer: -0.5 would be the most likley outcome

step-by-step explanation:

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°

hi there!

1. define: accuracy

a) how close a measured value is to the actual (true) value.

hope this : )
