1 answer:
I came up with something but not sure at all, so if you don't get anything better, check with your teacher to see if it makes any sense! After spendings Ruben deposits $32.5 So I ask; After how many of Shawna's $37.5 deposit + $750 will be equal to how many of Ruben's $32.5 + $850 i.e. 37.5x + 750 = 32.5x + 850 37.5x - 32.5x = 850 - 750 5x = 100 x = 20 weeks I check this Ruben = 32.5x20wks + 850 = 1500 for Shawna = 37.5x20wks + 750 = 1500 It actually checks out. Good luck..

What about it? What is the question?
We know that <span>The nine radii of a regular Nonagon divides into 9 congruent isosceles triangles </span>therefore [the area of <span>a regular nonagon]=9*[area of isosceles triangle] </span>[area of isosceles triangle]=b*h/2------> 15*20.6/2----> 154.5 cm² so [the area of a regular nonagon]=9*[154.5]------> 1390.5 cm²the answer is 1390.5 cm²
Answer:
B is correct
Step-by-step explanation:
I think you don't need a calculator here. :) Try to figure out next time!
The first blank is "division" and the second blank is "multiplying"
12 / (3) = 4
5 x 3 = 15
15 + 4 = 19
