The two domes or hemispheres simply have the area of a complete sphere with the same diameter. So the total area is the area of a sphere and a cylinder...
as=(4p3^3)/3, ac=10p3^2
A= 36p+90p=126p in^3
Answer:
sedan = 26 miles/gallon
truck = 17 miles/gallon
Step-by-step explanation:
try to write the text in mathematical format as a system of equations
t=truck s=sedan
![\left \{ {{3t+5s=181} \atop {7t+6s=275}} \right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7B3t%2B5s%3D181%7D%20%5Catop%20%7B7t%2B6s%3D275%7D%7D%20%5Cright.)
first equation can be written as
t= (181-5s)/3
we can use it in the second equation and rewrite it as
7[(181-5s)/3]+6s = 275
7(181/3 -5/3s) + 6s = 275
1267/3 - 35/3s + 6s = 275
-35/3s + 18/3s = 275-1267/3
-35/3s + 18/3s = 825/3 - 1267/3
-35s + 18s = 825 -1267
-17s = -442 s = 442/17 = 26 sedan has an average of 26 miles/gallon
we use this value of s in the first equation
3t + 5*26=181 3t=181-130 t= 51/3 = 17 truck has an average of 17 miles/gallon
Rate : 2.7 * 10 ^5 kg/hectare
m = 2.7 * 10^5 kg/hectare * 1.0 hectare = 2.7 * 10^5 kg
50°= 1/2
m ( Carbon ) = 1/2 * 2.7 * 10^5 kg = 1.35 * 10^5 kg
The mass of Carbon is 135,000 kg or 135 tons.
Answer: <B= 101, <C= 79, <D=101
Step-by-step explanation: all parallelograms have the diagonal angles equal so that is why <c=79. Parallelograms also have all angles equal to 360. so if you add <C, and <A you have 158. then you subtract that from 360 and you get 202. You then need to divide it by to to get the measures of angles B and D which are 101 each.
