Answer:   -1.4

The opposite of -1.4 is 1.4; you flip from negative to positive.

Then taking the opposite of 1.4 gets us back to -1.4 again

Effectively the two opposites cancel out and nothing changes.

A sector with an area of 26pie cm^2 has a radius of 6 cm. What is the central angle measure of the sector in radians?
Zolol [24]

Answer:

The central angle measure of the sector in radians is \theta=\frac{13}{9}.

Step-by-step explanation:

A sector of a circle is the portion of a circle enclosed by two radii and an arc. It resembles a "pizza" slice.

The area of a sector when the central angle is in radians is given by

                                                    A=(\frac{\theta}{2})\cdot r^2

where

r = radius

θ = central angle in radians

We know that the area of the sector is 26 \:cm^2 and the radius is 6 cm. Applying the above formula and solving for the central angle (\theta) we get that

                                                   26=(\frac{\theta}{2})\cdot (6)^2\\\\\left(\frac{\theta}{2}\right)\left(6\right)^2=26\\\\\frac{\frac{\theta}{2}\cdot \:6^2}{36}=\frac{26}{36}\\\\\frac{\theta}{2}=\frac{13}{18}\\\\\theta=\frac{13}{9}

For how long would a 68 kg person have to swim at a fast crawl to use all the energy available in a typical fast food meal of bu
irina1246 [14]
<span>Taking this to a Physics formula of Time equals energy times efficiency over power equals (5670kJ)(0.25) over 800J/s equals 1770 s which gives the solution 30 minutes. Therefore, it will take 30 minutes for a 68kg person to swim at a fast crawl in order to use all the energy available in a typical fast food meal of a burger, fries, and a drink. I estimated with a 25% efficiency for work capacity at swimming at a fast crawl in this equation.</span>

Dimensions of the bed

= 3in.  \:  \: by  \: \: 2 \frac{2}{3} in. \:  \: by \:  \:  \frac{1}{3} in.

<em><u>Therefore</u></em><em><u>, </u></em>

Volume of the bed

= (3 \times 2 \frac{2}{3}  \times  \frac{1}{3} ) {in}^{3}

= (2 \frac{2}{3}  \times 1) {in}^{3}
