Answer: C
Step-by-step explanation: they said they divided into uqual which 1/8= 1/4 Divide 1/4=.25
Answer:
y= - x + 9
Step-by-step explanation:
The 9 comes from the y- intercept which is 9
the slope is-1 cause the line goes goin down by one at a time
Answer:
90 cm, 180 cm, 240 cm
Step-by-step explanation:
Let the lengths of sides of the triangle be 3x, 6x and 8x
Hence, lengths of the sides of the triangle are 90 cm, 180 cm and 240 cm.
Wallsare 3 inches thick
diameter is 20 feet, find real diametter
legnth is 50 feet, find real legnth
minus 6 inches from each measurement since that is not included
20ft-6in=19.5ft
50ft-6n=49.5ft
we have a cylinder and a 2 hemispheres
2 hemispheres=1 sphere
Vcylinder=hpir^2
Vsphere=(4/3)pir^3
r=d/2
r=19.5/2=9.75
h=49.5
Vcylinder=49.5*pi*9.75^2=14783.058738886 ft^3
Vspere=(4/3)pi9.75^3=388419466778 ft^3
add them
Vcylinder+Vspher=14783.058738886+388419466778 ft^3=18665,478205664ft^3
V=18665,478205664 ft^3
times 7.48 to find gallons
Vingallons=139617.77697837 gallons
Answer:
Step-by-step explanation:
Using log(x) - log(y) = log (x/y)
logx^2 - log(x+6) = 1 is equal to:
log (x^2/(x+6)) = 1
Taking inverse base 3 log on both side:
x^2/(x+6) = 3
x^2 = 3x + 18
x^2 - 3x - 18 = 0
(x-6)(x+3) = 0
x = 6 or -3
