I think what you do is pretend it is a circle and find the circumference of the circle then cut that amount in half. The straight side of the semicircle is the diameter of the whole circle, so you add that to the half of the circle. Hope this helps (and wasn't explained badly)!

ratelena [41]

Answer:

Step-by-step explanation:

(x-2)(x+1)=3x-2

Write about how to use the dollar sign and decimal point to show the total value of 5 quarters
aivan3 [116]
So 1 quater is 25 cents each. 5 quaters would be 125 cents. We know that 4 quaters equal $1.00 So we now have 1 quater left, you can add 25 cents to one dollar and get $1.25
So we started off with 125 cents so we added in a decimal point and added in a dollar sign. Hope this helps.
