Answer:
<u><em>Stephanie runs the fastest per second: 14 feet per second</em></u>
Step-by-step explanation:
To find the fastest speed, you need to see which person runs the most per second:
Stephanie runs <em>14 feet per second</em>
<em />
Brooke runs 589 feet in 44 seconds.
Find the amount of feet per second by dividing:
Brooke runs about <em>13.4 feet per second</em>
<em />
Will runs 1 mile in 454 seconds.
Convert the miles to feet:
There are 5,280 feet in a mile. If Will runs 5,280 feet in 454 seconds, divide to find how much he runs per second:
Will runs about <em>11.6 feet per second.</em>
<em />
Rob runs 548 feet in a minute.
Convert the minute into seconds. There are 60 seconds in a minute. Divide the feet by the seconds to find how fast he runs per second:
Rob runs about <em>9.1 feet per second.</em>
Stephanie runs 14 feet per second, the fastest time:
| 14 |, 13.4, 11.6, 9.1
<em>Finito.</em>
The absolute value of |-2| is 2 then you have to add the negative sign on the outside, so the answer will be -2
Answer:
Step-by-step explanation:
given,
angular deceleration, α = -0.5 rad/s²
final angular velocity,ω_f = 0 rad/s
angular position, θ = 6.1 rad
angular position at 3.9 s = ?
now, Calculating the initial angular speed
now, angular position calculation at t=3.9 s
Hence, the angular position of the wheel after 3.9 s is equal to 5.83 rad.
First, you need to know that the total (degrees) of the interior angles is 360 because this is a quadrilateral.
The unnumbered angle is 109 degrees. We know this because the angle labeled 71 degrees and the unnumbered angle are supplementary. So you subtract 180 from 71 to get 109.
To solve for x, we need to realize the other numbers playing into the angles' values. To make solving this easier, I'm gonna assign letters to the angles.
(10x+6) is angle A.
(13x-2) is angle B.
(8x-1) is angle C.
and 109 (the one we solved) is angle D.
We know that the
total of the interior angles is 360, so we can add the 2 from angle B and the 1 from angle C to 360. This is because these numbers are subtracted from the other values.
Now, we have to subtract the 6 from angle A from 363, because the 6 is added to the other values.
Now we have to subtract 109 from 357 because you want to get the x's by themselves. Since you're solving for x.
That leaves you with 248. Now you add all the x's up to get the total number of x's. You have 10x from angle A, 13x from angle B, and 8x from angle C.
You get 31x. To get what x is, you divide 248 by 31.
That equals 8. So now that you know that x equals 8, if you need to find the values of the angles, you just plug in the numbers into the formulas.
Check your work by plugging your answers in and seeing if they add up to 360.
Which they should:)
So...
angle A= 86
angle B=102
angle C=63
angle D=109
and x=8
Hope this helped!!!
Answer:38
Step-by-step explanation:if you take 24 and subtract the five she added, it gives you 19 and since she divided it by two you would multiply it by two to get the original number she was thinking of
Hope this helps :)
