Answer:B
Step-by-step explanation:
3.1x10^9 is putting 9 zero’s behind the 3.1
move the decimal point over 9 spaces which will leave you with 3,100,000,000
= 3.1 Billion
Bed mass. 12(9)-24/12, 12(9)-2, 108-2 = 106
Answer:
The equation of the sphere in standard form is
Step-by-step explanation:
<u>Step 1</u>:-
The equation of the sphere having center and radius is
Given centered of the sphere is (-6,10,5) and radius r=5
on simplification,we get
simplify , we get
Answers:
13 42 m; B; 0.57 m
Step-by-step explanation:
Data:
Pool A: r = 22 ft
Pool B: D = 13.6 m
Calculations:
1. Radius of Pool A
r = 22 ft × (0.305 m/1 ft) = 6.71 m
2. Diameter of Pool A
D =2r = 2 × 6.71 = 13.42 m
The diameter of Pool A is 13.42 m.
3. Compare pool diameters
The diameter of Pool B is 13.6 m.
So, the diameter of Pool <u>B</u> is greater.
4. Compare circumferences
The formula for the circumference of a circle is
C = 2πr or C = πD
Pool A: C = 2π × 6.71 = 42.16 m
Pool B: r = π × 13.6 = 42.73 m
Pool B - Pool A = 42.73 - 42.16 = <u>0.57 m
</u>
The circumference is greater by <u>0.57 m.</u>
5y - 5= 22
or
5(y)-5=22
Hope that helps!
