Answer:

1/3

Step-by-step explanation:

The whole chore is 1, or 12/12

Subtracting the fraction of work done by A and B

12/12- 8/12 = 4/12

Which simplifies

4/12 = 1/3

A UFO is coming in to pick up some test subjects. Their elevation above the ground is 60,000 feet. Their laser sights tell them

charle [14.2K]

Answer:

41.83°

Step-by-step explanation:

It is given that :

The vertical distance of the UFO from the ground = 60,000 feet

The diagonal distance of the landing area to the UFO = 90,000 feet

In order to find the angle of depression, we have to use the trigonometric ratios, i.e.,

$\sin \ \theta = \frac{\text{perpendicular distance}}{\text{hypotenus}}$

$\sin \ \theta = \frac{60,000}{90,000}$

$\sin \ \theta = \frac{2}{3}$

$\sin \ \theta = 0.667$

∴ $\theta = \sin^{-1 }(0.667)$

= 41.83°

In December, the average total rainfall in all the deserts together is 0.89 mm. Explain how to use the fiqures from the table to

maw [93]

I know this is late but I can still help answer this....

So we know that in December all the deserts altogether had 0.89 mm of rainfall. Now the chart that you have seems to represent the rainfall in August, so we would need to use addition.
0.19 + 0.17 + 0.1 + 0.24 = 0.70 mm
The rainfall altogether would be 0.70 mm in August. Now we compare the difference, we would need to subtract 0.89 mm (December) with 0.70 mm (August).
0.89 - 0.70 = 0.19 mm
There the difference between the two would be 0.19 mm.

Hope this helps!

Answer:

The circunference is represented by the equation is $x^{2}+y^{2}-6\cdot x +4\cdot y +9=0$ .

The graph of this function is presented in the attachment.

Step-by-step explanation:

The general equation of the circunferece is defined by the following formula:

$x^{2}+y^{2}+A\cdot x + B\cdot y + C = 0$ (1)

We can determine the value of the coefficients by knowing three distinct points: $(x_{1}, y_{1}) = (3,0)$ , $(x_{2},y_{2}) = (5,-2)$ , $(x_{3},y_{3}) = (1, -2)$
