2log7-2r=0 with the 7 being a subscript(small)

Mathematics

5 0

Starting equation is <span>2<span><span>log7</span><span>(−2r)</span></span>=0</span>

First we can divide both sides by 2

<span><span><span>log7</span><span>(−2r)</span></span>=0</span>

Now we have to write the right side (0) as a logarythm.
Since <span><span>70</span>=1</span>, we can write 0 as <span><span>log7</span>1</span>, so the equation becomes:

<span><span><span>log7</span><span>(−2r)</span></span>=<span><span>log7</span>1</span></span>

We can skip log signs because both sides are logarythms and the base is the same:

<span>−2r=1</span>

Now if we divide the equation by (-2) we get the answer:

the insurance company pays the forecast of 3900 prescriptions claims out of 4500 prescription claims submitted what is the rate
nadya68 [22]

Answer:

x=0.87  or   86.67%

13 prescription claims out of 15 are paid

Step-by-step explanation:

First we organize the data:

prescription claims submitted: 4500

Prescriptions: 3900

The rate of claims paid is calculated using the following formula:

x =\frac{Paid}{Total}

We know that:

Paid = 3900

Total = 4500

So

x =\frac{3900}{4500}

x =\frac{39}{45}

x =\frac{13}{15}

x=0.87

What is the answer to <br> 12 - (1/2+2/3) =
Elena-2011 [213]
1/2 can be rewritten as 3/6, and 2/3 can be rewritten as 4/6 (find the lowest common denominator and in this case it is 6 because 2x3=6). 3/6+4/6=7/6. 12 can rewritten as 24/6, so do 24/6 - 7/6 and you answer is 17/6.

What is the m Show work
Ghella [55]

Answer:

measure of angle A is 80 degree.

Step-by-step explanation:

isosceles triangle will have same base angles

first base angle is 50, and the second will also be 50

3 angles of a triangle will add up to be 180 degree.

A is the vertex angle.

So 50 + 50 + A = 180

100 + A = 180

A = 80.
