0.2 is 10 times as much of... well you must do the opposite of what it says... well, times means to multiply and the opposite of multiplying is dividing, 0.2 divided by 10 is 0.02

So... 0.2 is 10 times as much as 0.02

Now, 0.2 is 1/10 of... well this question shows to divide and we must do the opposite, which is... multiplying 0.2 times 10 is 2

So... 0.2 is 1/10 of 2

A cell phone carrier charges a fixed monthly fee plus a constant rate for each minute used. Part 1. In January, the total cost f

rjkz [21]

Answer:

The constant charge for each minute used is $50

Step-by-step explanation:

In order to solve this problem we will need to set two variables up. In this case:

F = constant Fee

R = rate per minute used

So the cost for the month of January is calculated like this:

F+300R=68

and the cost for February is calculated like this:

F+275R=66.5

So no we have a system of equations we can solve simultaneously. This can be solved by using different methods, elimination, substitution, graphically or by using matrices. I will solve this by substitution.

So let's solve the first equation for R:

$R=\frac{68-F}{300}$

and let's substitute this first equation into the second equation:

$F+275(\frac{68-F}{300})=66.5$

and now we can solve this for F:

$F+11(\frac{68-F}{12})=66.5$

We can multiply both sides by 12 so we get:

12F+11(68-F)=798

12F+748-11F=798

F= $50

The terminal side of an angle θ in standard position is in quadrant 1. If sinθ=0.8, find cosθ.

Aloiza [94]

Answer:

$cos\theta=\frac{3}{5}$

Step-by-step explanation:

Since $sin\theta=0.8$ is the same as $sin\theta=\frac{4}{5}$ and $sin\theta=\frac{opposite}{hypotenuse}$ , then we know that the side opposite to the angle $\theta$ is 4 units and the hypotenuse is 5 units.
