Hi there! Let’s see if I can help you <3

The Answer is: 15.81!

Here’s the step by step explication:

First we must find the difference of U and V: (7i-12j)-(-2i+j)

Distributed all out will equal: 9i-13j

We can then go ahead and use Pythagorean therm to find the magnitude: V = Square root of (9)^2 + (-13)^2

This equals Square root of 250!

Depending on the form your teacher wants to answer in it would finally be 5 square roots of 10 or in decimal form; approximately 15.8114!

HOPE IT HELPED YOUUU <3

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>
