T ∝ 1/v
<span>so, t = k/v or tv = k </span>
<span>Then, with t = 2.5 and v = 5 we have: </span>
<span>2.5 = k/5 </span>
<span>so, k = 12.5 </span>
<span>Therefore, t = 12.5/v or vt = 12.5 HOPE IT HELPED</span>
Answer:
-1
Explanation:
Let the number be x.
Then the equation will be:
3(x+18) = 51
=> 3x + 54 = 51
=> 3x = 51 - 54
=> 3x = -3
=> x = -3/3
=> x = -1
So, the number you thought of is -1.

Answer:
The length of the arc is 15.7 centimeters
Step-by-step explanation:
The central angle measures 90 degrees. In order to find the length of the arc, we need to find the total circumference of the circle.
Circumference formula = pi x diameter
The diameter is just the radius doubled
pi x (10 + 10)
pi x 20 = 62.8
The total circumference is 62.8. We know that there are 360 degrees in a circle and 90 is 1/4 of 360.
So 62.8 / 4 = 15.7
The arc should be 15.7 cm
i think this is correct, sorry if its not
2*3.14*3.5*3.5+2*3.14*3.5*14=384.65 I hope this helps you out. :):):)
