1 = 4/r + 4/2r

multiply each side by 2r

2r = 8 +4

2r = 12

r = 6

It takes Julius 6 hours to do the job

It takes Darnell 12 hours to do the job

What is the area of a rectangle that is 3.1 cm wide and 4.4 cm long? Enter the full-precision answer first to see the correspond
Brrunno [24]

Answer:  Without rounding : 13.64 (square cm)

Rounded answer : 13.6(square cm)

Step-by-step explanation:

We know that the area of a rectangle is given by :-

A=l\times w, where l is the length and w is the width of the rectangle.

Given : The dimensions of a rectangle are 3.1 cm wide and 4.4 cm long.

Then, the area of rectangle will be:-

A=4.4\times 3.1=\dfrac{44}{10}\times\dfrac{31}{10}\\\\=\dfrac{1364}{100}=13.64\text{ cm}^2\approx13.6\ cm^2  \text{Rounded to the nearest tenth}

Therefore, the area of rectangle =13.6\text{ cm}^2

If cosVz=0.1673413807, find Vz.<br> Thanks- thold you it was easy.
12345 [234]

Answer:

Vz = arccos(0.1673413807) = 80.37º

Step-by-step explanation:

The inverse function of the cosine is the arc cosine.

That means, that if we have that cos a = 1, a is the angle which has cosine equals 1, so a = arccos(1) = 0º.

In this problem, we have that:

cos(Vz) = 0.1673413807

Vz = arccos(0.1673413807) = 80.37º

The mean of the scores obtained by a class of students on a physics test is 42. The standard deviation is 8%. Students have to s
NemiM [27]
<span><u><em>The correct answer is:</em></u>
16%.

<u><em>Explanation</em></u><span><u><em>: </em></u>
We use a z-score to answer this question.
<u>The formula for a z-score is:</u>
 z=</span></span>\frac{x-mue}{sigma}<span><span>,
where mue is the mean and sigma is the standard deviation.

<u>Using our information, we have:</u>
z=</span></span>\frac{50-42}{8} =  \frac{8}{8} = 1<span><span>.

Using a z-table, we see that the area to the left of, or less than, this score is 0.8413. We want to know how many students scored more than this, so we subtract from 1:
1-0.8413=0.1587, which rounds to 16%.</span></span>
