T - the time that Dennis spent exercising ( in hours );
4 hours - 800 calories
1 hour - 800 : 4 = 200 calories
Answer: D ) C = 200 t
Answer:
1675 ft
Step-by-step explanation:
For us to calculate how close the windmill is to the fire, if we imagine it as a triangle, the distance from watch tower to the fire will be:
tan θ= opposite/adjacent
opposite=140 ft
adjacent = x
θ=3°
Thus;
tan 3 = 140/x
x=140/tan 3
x = 2,671.359 ft
Now, the distance from watch tower to windmill will be:
tan θ=opposite/ adjacent
θ=8°
opposite=140 ft
adjacent=y
thus
tan 8 = 140/y
y = 140/tan8
y=996.15 ft
Now, the distance between fire and wind mill will be:
x - y = 2671.359 - 996.15
x - y = 1675.209 ≈ 1675 ft
Answer:
B)T=2.50c+1.50L that my answer
Answer:
4.38%
Step-by-step explanation:
<em>Assuming simple interest</em>, we start by writing the formula for simple interest.
Where
SI is the interest amount (328.13)
P is the principal amount (2500)
r is the rate of interest (what we need to find)
t is the time, in years (t = 3)
Since we want rate of interest, we re-arrange the formula to get r in terms of the other variables. Shown below:
Now we simply plug-in the information we know and find r:
To convert into percentage, we multiply by 100:
r = 0.0438 * 100 = 4.38%
