A.
(64x<span>² + 96x + 36) / (16x + 12)
= 4(16x</span><span>² + 24x + 9) / 4(4x + 3)
= 4*(4x + 3)(4x + 3) / 4(4x + 3)
= 4x + 3
b.
1.79 x 10^5 = 1.79 * 100,000 = 179,000
c.
(5.9736 x 10^24) + (4.8685 x 10^24)
= (5.9736 + 4.8685) x 10^24
= 10.8421 x 10^24
= 1.08421 x 10^25</span>
Answer:
see below
Step-by-step explanation:
A: radius of 12 ft
Changing to meter
12 ft * .305 m/ ft =3.66 meter
The radius is 3.66 meters
The diameter is twice the radius = 2*3.66 =7.32 meters
The circumference is
C = pi*d = 3.14 * 7.32 =22.9848 = 22.98 meters
B diameter is 7.5 meters
Pool B has a bigger diameter
C = pi * d = 3.14 * 7.5m = 23.55 meters
The difference is .57 meters
Since the cost of the telephone cost is 25 cents per minute, and by using the variable you provided, "t", the equation thus far is 25t=cost, or 25 multiplied by "t".
Since the telephone also charges 75 cents at the start, we just have to add it into our equation, making 75+25t=cost of telephone call in cents.
answer: 75+25t=cost of telephone call in cents
Answer:
And after operate we got:
So then the gragbe per capita on this was would be
Step-by-step explanation:
For this case we know the following info:
Total waste generated for a certain country in 2005 : 
Total population for this country in 2005 
And we want to estimate the garbage per capita or per person for 2005, and we can use the following formula:
And after operate we got:
So then the gragbe per capita on this was would be
