Im pretty sure the answer is 7.84. i got this because 7 is a whole number so it is in the whole number spot. Then, you have to get your denominator to 100. So, what times 25 equals 100? its 4. so you get 100 so whatever you do to your denominator you do to your numerator. so 21 times 4 is 84. so 84/100 is actually 7.84. Hope this helped

<span>Displacement is closely related to the volume of each cylinder. The radius should be squared and multiplied by Pi (3.14) and then multiplied by the height of the cylinder to calculate the volume of each cylinder. This value can then be multiplied by the number of cylinders to find the total displacement.</span>
Answer:
The value of y is 14.
Step-by-step explanation:
To find this, we first can replace the angle written as 2x with 50. Since the sides leading to that point are congruent, we know that they have the same angle.
Now given that fact, we can put the 2 - 50s along with the final angle and set equal to 180 (the measure of the combined angles in all triangles).
50 + 50 + 5y + 10 = 180
110 + 5y = 80
5y = 70
y = 14
