Answer:
25/64
Step-by-step explanation:
ratio of perimeters = 15/24 = 5/8
ratio of areas = square of ratio of perimeters
ratio of areas = (5/8)^2 = 25/64
168=-8x
-8 -x
-21 = x
Division, 168 divided by -8
Answer:
Step-by-step explanation:
f(x)/g(x)=(6x+2)/(x-7)
The only restriction upon the domain, possible values of x, is division by zero is undefined. So x cannot equal 7.
So the domain is all real numbers except 7. In interval notation the domain is
x=(-oo, 7),(7, +oo)
Answer: 8.3 ft
Step-by-step explanation:
Here, The volume of this perfectly spherical balloon is approximately 2361.7 cubic feet.
Since, the volume of a sphere, 
Where r is the radius of the sphere.
Here V= 2361.7 cubic feet
Therefore, 
⇒ 
⇒
≈8.3 feet
Thus, the radius of the sphere = 8.3 feet
2.9 or 2.90
2 is a whole number
9/10 is a fraction so you divide. so 9 because it is like 90/100. Basically it is a decimal and then a 9 :)
