Answer:

No, the point (273, 2) does not lie on the circle that is centered at the origin and contains the point (0, -4)

Step-by-step explanation:

The circle centered at the origin that contains the point (0,-4) has equation:

{x}^{2}  +  {y}^{2}  = 16

If the point (273,2) lies on this circle , then it must satisfy this equation:

{273}^{2}  +  {2}^{2}  = 74533

Since

16  \ne74533

The point does not lie on this circle.

A building company used 24 workers to prepare a building site. The site measured 30 acres and the work was completed in 10 days.
maks197457 [2]

Answer:

30 workers are required.

Step-by-step explanation:

If the site measured 30 acres and was completed in 10 days, then it can be said that on average \frac{30}{10} = 3\frac{acres}{day} were made.

Then, 24 workers completed 3 acres / day.

Then, \frac{24.workers}{\frac{3acres}{day}} = \frac{8..Workers * days}{acre}

8 workers can complete 1 acre per day

Now to know how many workers are needed to complete 45 acres in 12 days, we multiply:

8\frac{Workers * days}{acre}*\frac{45}{12} \frac{acres}{days} = 30.workers.

Finally, 30 workers are required.

To solve this problem it was assumed that everyone worked at the same pace, which may not be true, the fact that some work at a slower or faster pace than another could alter the result, causing them to finish less or more acres by day.

For the given triangle, x = 8.6 cm.

Step-by-step explanation:

Step 1:

In the triangle, the given angle is 35°, the hypotenuse side's length is 15 cm. Assume the opposite side's length is x cm. To determine the opposite side's length, we determine the sin of the angle. To calculate the sin of an angle, we divide the opposite side's length by the hypotenuse's length.

sin\theta = \frac{oppositeside}{hypotenuse} .

Step 2:

The opposite side's length = x cm.

The hypotenuse side's length = 15 cm.

sin\theta = \frac{oppositeside}{hypotenuse}, sin35=0.5735, sin 35 = \frac{x}{15} ,

0.5299=\frac{x}{15}, x = 0.5735(15) =  8.6025

So x of the given triangle measures 8.6025 cm, rounding this off, we get 8.6 cm.
