On the third step it adds 8 on both sides. You are suppose to subtract 8 on both sides.
Step-by-step explanation:
height of the cylindrical tank = 20m
circumference of the tank = 39m
volumn of tank =
perimetre formula = 2πrh
= 2 x 3.14 x r x 20 = 39
= 188.4r = 39
r = 188.4/39
r = 4.83
volumn = πr^/2
h
= 3.14 x 4.83^2 x 2 x 20
= 1465.05
volumn of tank = 1465.05
The given equation is confusing since it written straight
without any symbols or parenthesis. I can write the equation in two forms:
(1 / 4) d + 7 --->
1
and
(1 / 4 d) + 7 --->
2
For equation 1, the variable d is first multiplied by 1 /
4 before adding up with the number 7. So in this case, the correct phrase would
be something like:
“The sum of one fourth a number and seven”
For equation 2, this is more complicated since the
variable is on the denominator side. The number 1 is divided by the product of
4 and variable d then summed up with the number 7. The correct phrase for this
one would be something like:
“The sum of the quotient of one over four times a number
and seven”
Select which equation is the correct one.
