Radius is 15 cm
Circumference = 2 pi r
C = 2 x 3.14 x 15cm
C = 94.2 cm
94.2 cm x 4 (revolutions) = 376.8 = D
Answer:
Step-by-step explanation:
You need to specify what the goal of the problem is.
If Kai picked 7 times as many blueberries as Nico, then:
n + 7n + 297, or
8n = 297. Unfortunately, 8 does not divide evenly into 297, and we certainly are not interested in picking fractional blueberries.
If the problem mentioned 296 instead of 297 total blueberries, then
Nico (n) picked 47 blueberries and Kai picked 7 times that many, or 329.
Answer:
The answer is
Step-by-step explanation:
C. f(x) = 500(2)^x
2020
20 * .10 = 2 <em>(2 = 10% of 20)</em>
20 + 2 = 22
20 x .07 = 1.4 <em>(1.4 = 7% of 20)</em>
20 + 1.4 = 21.4
The price of a 20$ haircut with a 10% tax would be $22.
The price of a 20$ haircut with a 7% tax would be $21.40.
