Answer15 y-int. (sety=0) 5%-15 (set x=0) x=3. 13,0).
Step-by-step explanation:
So with this equation, since the volume of the cylinder is 96 pi, plug that into the V variable, and since the radius of one of the marbles is 3, plug that into the r variable. From here, we can solve for x: 
Firstly, solve the parentheses: 
Next, multiply 36 pi and x: 
Next, subtract 24 pi on both sides: 
Lastly, divide both sides by 36 pi, and your answer will be 
, or B.
Answer:
3.05 yards
Step-by-step explanation:
Arc length= 2π(r)(Θ/360)
given: 7 yards is diameter, 50 degrees
radius= diameter/2 = 3.5
plug in
2π(3.5)(50/360) = 3.05 yards
Answer:
X - Y = 11 -------1
2x + y = 19 --------2
<em><u>Solving</u></em><em><u> </u></em><em><u>by</u></em><em><u> </u></em><em><u>elimination</u></em><em><u> </u></em><em><u>method</u></em><em><u> </u></em>
Multiple equation 1 by 2
2( X - y )= 22
2x - 2y = 22
2x + y = 19
Y = 3
Putting value of y= 3 in equation 1
X - 3 = 11
X = 11 + 3
X = 14
<h3>Value of X = 14 and Y = 3 </h3>
