Answer:
320
Step-by-step explanation:
multiply by 10 and get rid of the decimal
Answer:
undefined
Step-by-step explanation:
slope = ((y2-y1)/2) / ((x2 - x1 )/2)
since x1 = x2
so x2 - x1 = 0
then ((y2-y1)/2) / 0 = undefined
Answer:
4.55 mi N70°E, or 4.6 mi n70°E
Step-by-step explanation:
Draw a diagram; it helps keep the trig functions straight.
Starting from (0,0) a walk of 2 mi at N40°E leaves him at
x = 2sin40° = 1.29
y = 2cos40° = 1.53
Now, a walk 3 mi due east leaves him at
(4.29,1.53)
The new bearing is an angle θ with tanθ = 4.29/1.53 = 2.80
so, the new location is 4.55 mi N70°E
Answer:
Step-by-step explanation:
<u>Given:</u>
- Weight on Earth = 70 pounds
- Weight on Mars = 28 pounds
<u>As per given the proportion is:</u>
<u>A rock that weights 250 pounds on Mars would weigh on Earth:</u>
- 250/x = 2/5
- x = 250*5/2
- x = 625 pounds
Answer:
12 meters
Step-by-step explanation:
The assumption regarding shadow lengths is that they are proportional to height at any given place and time.
__
Here, the streetlamp is 9/6 = 3/2 times as tall as the tree, so we expect its shadow to be 3/2 times the length of the tree's shadow.
(3/2)(8 m) = 12 m
The streetlamp's shadow is 12 meters long.
