780-250 rounding to the tens place seems closes
if you find the compatible numbers to the hundreds place seems to far off of an estimate but that's just me

I would pick 750 - 250 because that equals 500. You can also prefer using 800 - 250.

Try, check, and revise or write an equation to solve
iragen [17]

Answer: 7 and 42.

Step-by-step explanation:

Let the two whole numbers be x and y.

From the question given, we can form an equation as:

x × y = 294 ........ i

x/y = 6 .......... ii

From equation ii

x/y = 6

x = 6y

Put the value of x back into equation i

x × y = 294

6y × y = 294

6y² = 294

y² = 294/6

y² = 49

y = ✓49

y = 7

Since x × y = 294 and y = 7,

x = 294/7

x = 42

The numbers are 7 and 42.

How many laps around the track is 5000 meters?
fredd [130]
Depending on the size of the track but from what I know, they are normally 400 meters for 1 lap. All you need to do is 5000 divided by 400 which is 12.5 so 5000 meters is 12 and a half laps around the track.

Cos 0 = 12/15. find sin 0.
valentina_108 [34]

Answer:

sin \theta = \frac{3}{5}

Step-by-step explanation:

cos \theta = \frac{12}{15}\\\\cos^2 \theta = 1 - sin^2 \theta\\\\sin^2\theta = 1 - cos^2  \theta\\\\

       = 1 - (\frac{12}{15})^2\\\\= 1 - \frac{144}{225}\\\\= \frac{225 - 144}{225}\\\\=\frac{81}{225}

sin \theta = \sqrt{\frac{81}{225}}  = \frac{9}{15} = \frac{3}{5}
