B and D
Step-by-step explanation:
Answer:
125.8983
Step-by-step explanation:
Use the formula for volume of a cone: v= (1/3)(3.14)(radius squared)(height) so v = (1/3)(3.14)(20.25)(6) = 125.8983
Step-by-step explanation:
replace the value of x with 1
y + 0.5 × 1 × y = 1 + 2
do the maths
y + 0.5y = 3
here the value of y is equal to 1. same goes for x, if we have no given value for them.
1.5y = 3
y = 3/1.5
y = 2
Answer:
x=5/2, y=-3/2. (5/2, -3/2).
Step-by-step explanation:
2=2y+5
3y-3x=-12
--------------
2-5=2y
2y=-3
y=-3/2
3(-3/2)-3x=-12
-9/2-3x=-12
3x=-9/2-(-12)
3x=-9/2+12
3x=-9/2+24/2
3x=15/2
x=(15/2)/3
x=(15/2)(1/3)
x=15/6=5/2
