Answer:
1282.5
Step-by-step explanation:
Step-by-step explanation:
first distribute
6x - 36 + 4 = 32 + 6x
combine like terms
6x - 32 = 32+ 6x
subtract 6x from both sides and add 32
0 = 64
therefore no solutions to this problem
Alrighty
vsphere=(4/3)pir^3
vcylinder=hpir^2
vempty=vcylinder-2vsphere
first the cylinder volume
ok, the height=2 times the diameter=2 times 2 times radius=4 times 3.75=15 cm
the radius is 3.75
v=15pi3.75^2
v=15pi14.0625
v=210.9375pi
vsphere=(4/3)pir^2
vsphere=(4/3)pi3.75^2
vsphere=(4/3)pi14.0625
vsphere=(56.25/3)pi
vsphere=18.75pi
2vsphere=37.5pi cm^3
so vcylinder-2vsphere= 210.9375pi cm^3-37.5pi cm^3=173.4375pi cm^3
using pi=3.141592
vempty=544.8698625 cm^3
about 545 cm³
Answer:
7x + 2y = -22
Step-by-step explanation:
Standard form looks like Ax + By = C.
Start with Y = -7/2x-11. Better to write that as Y = (-7/2)x - 11 to emphasize that the coefficient of x is the fraction -7/2.
Move the (-7/2)x term to the left:
(7/2)x + y = -11
Multiply all terms by 2 to eliminate the fractions:
7x + 2y = -22 (answer)

Answer:
D. 13.8
Step-by-step explanation:
FE being the midsegment means E is the midpoint of BC. The midpoint divides the segment into two equal parts, so BE = EC = 6.9. The length BC is the sum of those parts:
BC = BE +EC = 6.9 +6.9 = 13.8
The length of BC is 13.8 units.
