Answer:
A=pir²
Step-by-step explanation:
pi=3.14
r=15
r²=15²=225
A=225× 3.14= 706.5
Distance formula is SquareRoot of (x2-x1)^2 + (y2-y1)^2
= SQRT( (8-0)^2 + (-8-7)^2 )
=SQRT(64 +225)
=SQRT(289)
= 17
Answer:
300(1.0125)^12t
Step-by-step explanation:
P=300
R=0.15
N=12
substitute them into the equation P(1+r/n)^nt and then simplify the equation. The answer should be 300(1.0125)^12t
Answer:
7,7, and 7
Step-by-step explanation:
If she vase is cubical we know that all 3 dimensions are the same. This means that x^3 = 343. So we know the answer is the cube root of 343, which is 7
Let's say that x represents hours that Elizabeth volunteers over 1 week. Katie volunteers x+3 and Siobhan x-1 hours per week. The equation that arises from condition in text is:
3*(x+3) = 3*(x + x-1)
x+3 = 2*x - 1
2*x - x= 3+1
x=4.
Elizabeth volunteers 7 hours
Katie volunteers 4 hours
Siobhan volunteers 3 hours
