I believe if I did the expression correctly, the solution is 1
350 because 25x10 is 250 and 20x5 is 100 so you add them and get 350
Answer:
Step-by-step explanation:
use
i=prt
i=interest
p= principal value
r=rate
t=time
now you want to find time then it will be
t= i/pr
put values
t= 3722/(2000*7.6%)
t= 2 years
calculation is in fraction but your question given you annual interest so time will also be 2 years not in months
A) The formula for surface area of a sphere is A = 4*PI*r^2
using 3.14 for PI:
Surface area for Earth = 4 * 3.14 x 3960^2 = 196,960,896 miles^2
Surface area of the moon: 4 * 3.14 * 1080^2 = 14,649,984 miles^2
B)Divide the Surface of the Earth by the moon:
196,960,896 / 14,649,984 = 13.44
The Earths surface is 13.4 times larger than the moon.
C) Multiply the surface of the Earth by 70%:
196,960,896 * 0.70 = 137,872,627.2 million square miles of water.
Answer:
2411.52 cm³
Step-by-step explanation:
V = (2/3)πr³ Use the equation for volume of a hemisphere
V = (2/3)(3.14)(8)³ Simplify the exponent
V = (2/3)(3.14)(512) Multiply
V = 1071.79 cm³
V = πr² h/3 Now find the volume of the cone
V = (3.14)(8)²(20/3) Simplify the exponent
V = (3.14)(64)(20/3) Multiply
V = 1339.73 cm³
Add both of the volumes together to get the volume of the figure.
1071.79 + 1339.73 = 2411.52 cm³
