50-10 = 40. 40 divided by 6 = around 6/7. So about 6/7 weeks

How do you round off 639,121 to the nearest ten thousand?

maxonik [38]

You want to find the closest ten thousand that there is to 639,121.

So a ten thousand is basically anything that ends with four or more zeros.

For example:

530000 would be a ten thousand because it has four zeros at the end.

So you can see what the closest ten thousands are to 639,121 would be.

They would be:

630,000 and 640,000

Since they both have four zeros at the end.

Now you can just tell that 639,121 is closer to 640,000 because the digit in the thousands place, 9, is closer to 10 than 0.

Hope this helped :)

An angle whose measure is 405° is in standard position. In what quadrant does the terminal side of the angle fall?

katrin2010 [14]

Answer:

The angle is in the first quadrant

Step-by-step explanation:

For angles greate than360°,subtract

360° from the angle until the angle is less than 360°. Hence

405° = 405° - 360°

= 45°

The angle is in the first quadrant. Since the first quadrant can still take as much as 90°

Joe is making a ramp.Find the length of the ramp if the height is 7meters and the base is 24 meters

Musya8 [376]

Answer:

the length of the ramp is 25 meters

Step-by-step explanation:

Joe is making a ramp. Ramp forms a right angle triangle with the base

So we use Pythagorean theorem to find the length of the ramp

AC^2(hypotenuse) = AB^2 + BC^2

Length of ramp is the hypotenuse = $\sqrt{height^2 + base^2}$

= $\sqrt{7^2 +24^2}$

= $\sqrt{49 + 576^2}$

= $\sqrt{625}$

= 25

so the length of the ramp is 25 meters

What is the area of a sector with a central angle of 8 π/11 radians and a radius of 7.2 ft? use 3.14 for π and round your final

coldgirl [10]

Answer:

$59.19 ft^2$

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=7.2\ ft$

$\pi =3.14$

substitute

$A=(3.14)(7.2)^{2}$

$A=162.78\ ft^2$

step 2

we know that

The area of a circle subtends a central angle of 2π radians

so

using proportion

Find out the area of a sector with a central angle of 8 π/11 radians

$\frac{162.78}{2\pi }\frac{ft^2}{rad} =\frac{x}{(8\pi/11)}\frac{ft^2}{rad} \\\\x=162.78(8/11)/2\\\\x=59.19\ ft^2$
