Okay so you must do the (18-7) first so with that you will get
8*[5+11]/11
next you do the parenthesis yet again so [5+11]=16
8*16/7
and then you simplify
I got : 18.28.
I would take 84 times 3 for the three tests which gives you 252. I would then subtract the two test they took which is the 90 and 82 for a total of 172. 252-172 =80. The lowest score would be an 80
M = 0.01w
So for a 10 pound dog, m = 0.01(10) = 0.1 mg
Also, since 10 pounds is 1/5 of 50 pounds, then 1/5 of 0.5 mg is 0.1 mg.
With either calculation, the dose is 0.1 mg
Answer:
<em>75.408 ft</em>
Step-by-step explanation:
In 20 minutes, the angle swept by a minute hand is calculated as
(20/60) x 360° = 120°
The length of the minute hand = 36 ft
To calculate the distance moved by the minute hand, we solve for the fraction of the circumference of a circle swept by the minute hand in going through this 20 min.
we use the expression
Distance moved by the tip of the minute hand d = (θ/360) x 2πR
where
θ is the angle swept in the 20 minutes = 120°
R is the length of the minute hand, which is the radius of the circle formed if the minute hand moves completely in a 360° motion round the clock.
R = 36 ft
substituting values, we have
d = (120/360) x (2 x 3.142 x 36) = <em>75.408 ft</em>
