Vavilen inflated a huge balloon in 19 minutes. Then he poked a hole in the balloon so that it slowly leaked air out until it was

kaheart [24]

Considering balloon to be an spherical object

Volume of sphere = $\frac{4}{3}\pi r^3$ , where r is the radius of sphere.

After 19 minutes ,If radius of balloon changes from r to R, the Volume changes from V to V'.

V'= $\frac{4}{3}\pi R^3$ ,

As given,rate at which the air leaked out of the balloon (in liters of air per minute) was half of the rate at which Vavilen inflated the balloon.

Also, $\frac{dR}{dt}=2 \times \frac{dr}{dt}$

Now, again the radius changes from R to r.So, Volume changes from V' to Back to V.

Time taken by the balloon to deflate = 38 minutes

But there is no relation between time and volume of Balloon.

So, we can't predict at which rate balloon is deflating or inflating.Apart from the statement given in Question: $\frac{dR}{dt}=2 \times \frac{dr}{dt}$

Mr. Gold had 4 times more cars than motorcycles in his garage. After he bought 4 more cars and sold 4 motorcycles, there were 8

fenix001 [56]

Answer: 36 cars and 9 motorcycles

Step-by-step explanation:

It's given that he has x motorcycles to 4x cars
After he bought the cars and sold the motorcycles, he had 4x+4 cars to x-4 motorcycles
Since after this selling/buying, he has 8 times more cars than motorcycles, you can write the equation 4x+4=8(x-4)
Once you solve you get 36 cars and 9 motorcycles

What is the equation in standard form of the line y=1/9x + 5

Maurinko [17]

<h2><em>The standard form for the equation of a line is Ax+By=C In this case with the equation y=1/9x+5 B=1 and A=1/9 and C=5 in order to get Ax and By on the same side we can subtract 1/9x from both sides to get this in the correct form and we get </em><u><em>Y-1/9x=5</em></u><em> </em></h2><h2 />

What is the volume of this prism?

poizon [28]

Answer:

26.25 cubic inches

Step-by-step explanation:

To find the volume of a rectangular prism, you simply need to multiply together the lengths of all the varying side lengths. $3\frac{1}{2}\cdot5\cdot 1\frac{1}{2}=26.25$ . Hope this helps!
