We solve for the diameters of radius of the given circles by using the equation,
C = πD
or C = 2πr
where D and r are diameter and radius, respectively.
Solving,
C = 34.54 units
D = C/π = 34.54 units / 3.14 = 11 units
r = C / 2π = 34.54 units/2(3.14) = 5.5 units
C = 59.66 units
D = C/π = 59.66 units/3.14 = 19 units
r = D2 = 9.5 units
C = 23.236 units
D = 23.236 units/3.14 = 7.4 units
r = D/2 = 3.7 units
C = 23.376 units
D = 23.376 units / 3.14 = 7.4 units
r = D/2 = 3.7 units
C = 13.188 units
D = 13.188 units/3.14 = 4.2 units
r = D/2 = 2.1 units
As the sun went down, its heat is no longer warming the air and Earth.
Put number five as a common factor.
15x + 35y + 40z = 5 . 3x + 5 .7y + 5 .8z
= 5 . ( 3x + 7y + 8z )
Answer:
f=8/5
Step-by-step explanation:
f*2+=f7
2f+8=f*7
2f+8=7f
2f=7f-8
2f-7f=-8
-5f=-8
2v+18=16-4(v+7). Take away the parenthesis.
2v+18=16-4v-28. Combine your like terms.
2v+18=-12-4v. Add 12
2v+30=-4v. Subtract 2v
30=-6v. Divide by -6
v=-5. This is your final answer.
