Answer:
Step-by-step explanation:
(7 + 2)/(5 - 2)= 9/3= 3
y + 2 = 3(x - 2)
y + 2 = 3x - 6
y = 3x - 8
Answer:
sp with vat=9040
d=20%
vat=13%
mp=?
Step-by-step explanation:
sp with vat=9040
sp+vat%of sp=9040
sp(1+13/100)=9040
sp=9040/1.13=8000
- mp=sp+d%ofmp
- mp-d%ofmp=sp
- mp(1-20/100)=8000
- mp=8000/0.8=10000
62.5%, Because you do 5 divided by 8 that would be 0.625. move te decimal over two places and you have your percent.
Volume = area of base x height
area of base = 1/2 x base x height x number of central angles
area of base = 1/2 x 7 x 6.1 x 6 = 128.1
volume = 128.1 x 19 = 2433.9 cubic feet
A=LW and L=W+6, W=L-6 using this W in the area formula
A=L(L-6)
A=L^2-6L
L^2-6L-A=0 and we are told that area=72 so
L^2-6L-72=0 factor
L^2-12L+6L-72=0
L(L-12)+6(L-12)=0
(L+6)(L-12)=0, since L>0
L=12 meters
