Answer:
Therefore, beats per minute did increase for 36.
Step-by-step explanation:
48: 2/3=x:1
48=2/3 × x
x=3/2×48
x=72
81:3/4=x:1
81=x×3/4
x=4/3×81
x=108
Therefore, beats per minute did increase for 36.
Answer:
15+18
Step-by-step explanation:
3(5)+3(6)=15+18
Answer:
48
Step-by-step explanation:
47.999
The number in the thousands place is above 5, so add 1 to the digit in the hundreds places
47.90 + 0.09+0.01
47.9+0.1
48
Answer:
16% = 73.6
Step-by-step explanation:
If 1% is = 4.6 then 16% is
1* 16 % = 4.6 * 16
16% = 73.6
Given that, a sphere has a surface area of about 999 square millimeters.
Formula to find the surface area of sphere is,
S= 4πr² Where r = radius of the sphere and S= surface area.
Given S= 999 square millimeters.
So, we can write:
4πr² = 999
4 * 3.14 * r² = 999 Since, π = 3.14
12.56 *r² = 999
Divide each sides by 12.56.
r² = 79.53821656
r = √79.53821656 Taking square root to each sides of equation.
r = 8.918420071
So, r = 8.918 Rounded to nearest thousandth.
So, radius of the sphere is 8.918 millimeters.
Hope this helps you!
