Step-by-step explanation:
What
are you calculating area or circumference??
Answer:
1) c 226
2)
1. E
2. D
3. B
4. A
5. C
Step-by-step explanation:
6^3=216
5x(4-2)
5x2=10
216+10=226
Answer:
no.
Step-by-step explanation:
the 4 on the sides are half the area of the ones of the top and bottom because if you take two small ones they will fit with one of the big ones.
sorry if I'm wrong.
Answer:
Step-by-step explanation:
<u>The line x = 3 is parallel to y- axis, the perpendicular line is going to be parallel to x- axis and will have an equation:</u>
<u>Since it passes through the point (-2, 5), it will have a = 5:</u>
- y = 5 is the line we need
<span>The two fires are about 70 feet from each other.
The assumption is that the ground is relatively level and that a right triangle will be made with the three points of the triangle being the ranger, the spot on the ground directly beneath the ranger, and the fire itself. So the distance to the first fire will be:
Calculate the angle. That will be 90° - 11.6° = 78.4°
The distance will be
tan(78.4) = X/60
60 tan(78.4) = X
60 * 4.871620136 = X
292.2972082 = X
And that's how far the 1st fire is from the ranger's station. Now for the 2nd
angle = 90° - 9.4° = 80.6°
60 tan(80.6) = X
60 * 6.040510327 = X
362.4306196 = X
And the distance between the two fires will be the difference in distance from the tower, so
362.4306196 - 292.2972082 = 70.13341146
Rounding to 2 significant figures gives 70 feet.</span>
