You would use this formula for the problem...
(C=2πr) The circumference equals 2 multiplied by pi and radius.
In this problem it says diameter, but the diameter is just twice the length of the radius, so just multiply the radius by 2. Plugin your number.
C=2π(2) since 2 is half of 4, that's your radius.
Your answer is roughly C= 12.57.
You're welcome.
The formula for the area of a trapezoid is Area = (top + bottom)/2 x height
Using the given information we can solve for x:
234 = (20+32)/2 * X
234 = 52/2 * X
234 = 26 * X
X = 234/ 26
X = 9 units.
The answer is B.
3(x+4)-10 = 1/10 (4x+16)
3x+12-10 = 1/10*2 (2x+8)
3x+2 = 1/5* (2x+8)
3x+2 = 2/5x + 8/5
15x+10 = 2x+8
15x-2x=8-10
13x = -2
x = -2/13
She made her mistake when she forgot about the 1/10 and didn’t include it
Answer:
14.29
Step-by-step explanation:
Let p be the price of the cd
we take the price of the cd plus the tax and it must be less than or equal to 15
the tax is the price of the cd times 5 %
p + p*.05 ≤15
Combine like terms
p*1.05 ≤15
Divide each side by 1.05
p ≤15/1.05
p ≤14.28571429
Rounding to the nearest cent
p ≤14.29
The maximum price is 14.29
