It’s between two and three which might turn out to be a decimal
A hemisphere. The formula for a hemisphere is V = (2 / 3)πr^3<span>. r is the radius. if you are given a radius, plug it into the formula to find the answer if a radius is given. </span>
A^2+b^2= 15^2
b=a-3
Use substitution
a^2+(a-3)^2= 225
a^2+a^2-6a+9=225
2a^2-6a=-216
2a^2-6a+216=0
2(a^2-3a+108)
2(a-12)(a+9)
(a-12)=0
a=12
(a+9)=0
a=-9
A is -9 or 12, but since an object can't have a negative length or width, a must be 12.
Plug this value of a in.
b=(12)-3
b=9
Final answer: Length=9, width=12
Answer:
x = 
Step-by-step explanation:
Given
32x + 1 = - 3x + 5 ( add 3x to both sides )
35x + 1 = 5 ( subtract 1 from both sides )
35x = 4 ( divide both sides by 35 )
x =
