I am a decimal

0.6<2x<0.65 (because it's closer to 6)
0.3<x<0.325

Since the thousandths digit of 2x is 2, then the thousandths digit of x is 1 or 6, so the decimal could be 0.301, 0.302, 0.311, 0.312, 0.321

Hope this helps :)

Numbers greater than 0.3 and less then 0.35 are between .6 and .7 when doubled.

Lets assume it is a decimal that goes up to the thousandths.
0.310 to 0.324 Would be closer to .6 than .7. We know the thousands digit has to be a 1 or a 6 because its double ends in a two. So it looks like our options are .311, .316 and .321.

Fine the area of a circle that has a diameter of 12 inches A=3.14r2

Alexus [3.1K]

The area of circle is 113.04 in^2

Further explanation:

The area of circle is calculated by using pi and radius.

We are given

Diameter = d = 12 inches

pi = π = 3.14

$r = \frac{d}{2} = \frac{12}{2} = 6\ inches$

$Area = \pi r^2\\= 3.14 * (6)^2\\= 3.14 * 36\\=113.04\ in^2$

The area of circle is 113.04 in^2

To estimate the height of a mountain, two students find the angle of elevation from a point (at ground level) b = 800 meters fro

Nady [450]

Answer: The height of the mountain is 1,331.4 meters (approximately)

Step-by-step explanation: From the information given, the students were standing at point b which is 800 meters from the base of the mountain and the angle of elevation from that point is 59°. Assuming that the ground is level, we can derive a right angled triangle from this set of details and hence we have triangle ABC, where angle β is the reference angle, (59 degrees), BC is the distance from the students to the base of the mountain (800 meters) and the line AC is the height of the mountain.

The line AC is the opposite, since angle B is the reference angle, therefore we shall use the trigonometric ratio as follows;

Tan β = opposite/adjacent

Tan 59 = AC/800

Tan 59 x 800 = AC

1.6643 x 800 = AC

1331.44 = AC

AC ≈ 1331.4

Therefore the height of the mountain is approximately 1,331.4 meters
