lara31 [8.8K]

Answer 55%

Step-by-step explanation:

you need to add the values together

160+1100+740=2000

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 2000 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 2000, so we can write it down as 100%=2000.

4. We know, that x% equals 1100 of the output value, so we can write it down as x%=1100.

5. Now we have two simple equations:

1) 100%=2000

2) x%=1100

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=2000/1100

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1100 is what percent of 2000

100%/x%=2000/1100

(100/x)*x=(2000/1100)*x - we multiply both sides of the equation by x

100=1.81818181818*x - we divide both sides of the equation by (1.81818181818) to get x

100/1.81818181818=x

55=x

x=55

now we have:

1100 is 55% of 2000

The radius of a sphere-shaped balloon increases at a rate of 2 centimeters (cm) per second. If the surface area of the completel

frez [133]

Considering the surface area of the spherical ballon, it will take 7 seconds for the the balloon to fully inflate.

<h3>What is the surface area of a sphere?</h3>

The surface area of a sphere of radius r is given by:

$S = 4\pi r^2$

In this problem, the surface area is of $784\pi$ cm², hence the radius in cm is found as follows:

$784\pi = 4\pi r^2$

$4r^2 = 784$

$r^2 = \frac{784}{4}$

$r^2 = 196$

$r = \sqrt{196}$

r = 14 cm.

The radius start at 0 cm, inflating at a rate of 2 cm/s, hence it will take 7 seconds for the the balloon to fully inflate, as 14 cm/(2 cm/s) = 7 s.
