Sean took 6 tests and currently has an average of a 90. His range of his scores was 18 and the mode of the test scores is 89.

what is the question?

Step-by-step explanation:

Below.

Step-by-step explanation:

Total scores = 6*90 = 540.

He had more than one 89 ( mode) and max score - min score = 18.

Let max score = x then min = x-18.

Lets say he has 3 89's then

x +  x - 18 + 3*89 + y  = 540  where y is another score then:

2x + 249 + y = 540

2x + y =  291

x = 98 and y = 95 will fit this so the 6 scores could be

80, 89, 89, 89, 95, 98.

x/7.50 = 15

x= 7.50 / 15 divide

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
