You have prices to rev

Alex17521 [72]

Answer:

34 minutes

Step-by-step explanation:

Given

$Time\ Spent = 6$

$Phone\ Calls = 40$

Required

Number of minutes left to spend (x)

Since there's only 1 minute left to spend on every other call;

Time left = x * 1

Time left = x

The required can further be calculated using:

$Time\ Spent + Time\ Left = Phone\ Calls$

This gives:

$6 + x = 40$

Subtract 6 from both sides

$x = 40 - 6$

$x = 34$

<em>Hence, there are 34 minutes left to spend</em>

The volume of a cylindrical container

Ray Of Light [21]

Answer:

A. $\frac{3}{4}\textrm{ gal}$

Step-by-step explanation:

Given:

Volume of the cylindrical container before dilation, $V_{i}=1\textrm{ gal}$

Scale factor of the dilation, $SF=\frac{3}{4}$

Therefore, the volume of the dilated cylinder is given as:

$V_{f}=SF\times V_{i}$

Plug in 1 gal for $V_{i}$ and $\frac{3}{4}$ for SF. Solve for $V_{f}$ . This gives,

$V_{f}=\frac{3}{4}\times 1\\V_{f}=\frac{3}{4}\textrm{ gal}$

Therefore, the volume of the dilated cylinder is $\frac{3}{4}$ gallons.
