1. get rid of your parenthesis
2. in order to do so you must look inside of the parenthesis and check if you have any like terms if so combine them
3. next use the distribution property or otherwise known as the rainbow
4. if you have an exponent to the right of your parenthesis then use the exponent rule
5. combine like terms by adding coefficients
6. finally combine the constants

Answer:
<h2>The required ratio is 8</h2>
Step-by-step explanation:
Volume of a sphere =
where r is the radius of the sphere.
If manuel bought a balloon (that is a perfect sphere) with a radius of 2cm, the original volume of the sphere is expressed as;
Vo = 

If he wanted his balloon to be bigger and he blew 2 big breaths of air into the balloon, if each big breath increased the balloon's radius by 1cm, the total radius will be the initial radius of the sphere plus the new radius after expansion.
radius of current sphere = 2cm+(1cm+1cm) = 4cm
Volume of the current sphere Vc = 

The ratio of the current volume of the balloon Vc to the original volume of the balloon Vo will be expressed as;
Vc/Vo = 

The required ratio is 8
Answer: Sabrina read 65 pages on the second and third days
Step-by-step explanation:
45 + 2x = 175
45 - 45 + 2x = 175 -45
2x = 130
2x/2 = 130/2
x = 65
CHECK: 45 + 65 +65 = 175
Step-by-step explanation:
Given that,
Radius of circle, r = 38 cm = 0.38 m
It rotates form 10 degrees to 100 degrees in 11 seconds i.e.


Let
is the angular velocity of the particle such that, 


We need to find the instantaneous velocity of the particle. The relation between the angular velocity and the linear velocity is given by :


v = 0.053 m/s
So, the instantaneous velocity of the particle is 0.053 m/s. Hence, this is the required solution.
