Answer:
c.13.7mi, A=33.3°, B=56.7°
Answer:
14.13
Step-by-step explanation:
use the radius, 3 squared
so 3 x 3 = 9
9 x 3.14 = 28.26
28.26 / 2 ( because it is a semicircle) = 14.13
Answer:
Her first coupon ti be used is $50 off a purchase above $300
Final purchase price= $340
Step-by-step explanation:
Marie has two coupons
one for a 15% discount and one for $50 off any purchase above $300.
The stores allow the two coupons to be combined and she spends a total of $450.
Her first coupon ti be used is $50 off a purchase above $300.
So Marie have $400 now
15% off $400= 400-(0.15*400)
15% off $400 = 400-60
15% off $400 =$ 340
To multiply these two binomials, we will use the F.O.I.L. method.
First-Outer-Inner-Last
First take the product of the first terms, which is 20x².
Then take the product of the outer terms which is 8x.
Then the product of the inner terms which is -20x.
Lastly take the product of the last terms which is -8.
Now let's combine like terms.
So our final answer is 20x^2 - 12x - 8.
