Answer:
$11 sales tax per $200
Step-by-step explanation:
1375/25,000 = 11/200
We need to set up an equation for this (with a being the accessories) and then solve.
4a+a=220
5a=220
-- ----
5 5
a=44
So now we know the accessories cost $44. The bike cost 4 times as much. 44x4=176.
He received $176 for the bike.
Answer:
301.593
Step-by-step explanation:
surface area = circumference x height + 2 x circle area
= 4 x 2 x π x 8 + 2 x π x 4^2
= 25.1327412287 x 8 + 6.28318530718 x 16
= 201.06192983 + 100.530964915
= 301.592894745 ≈ 301.593
Answer:
The statement at the top says that the triangles are 'similar'. That means that the corresponding angles are equal, and each pair of corresponding sides have the same ratio. From the 4 and the 8, you can see that each side in the small one is 1/2 the length of the corresponding side in the big one. So the missing sides are 1/2 the length of the 7 and the 12.
