Answer:
original price = $40
Step-by-step explanation:
if 70% ---> $28 then
1% ---> $28/70 = $0.4
then we know original price should be 100%
original price = 100 * 0.4 = $40
OR
basic easy function:
(28/70) * 100
$40
Write <em>z</em> in exponential form:
Then taking the logarithm, we get
so a is the correct answer.
Step-by-step explanation:
De qué forma how is your night give me a picture
Proportion
3 parts milk. 12cups
2 parts sugar X
8 cups sugar
Let
b-----------> the length side of the square box
h------------> the height of the box
SA---------> surface area of the box
we know that
[volume of the box]=b²*h
volume=256 in³
b²*h=256-------> h=256/b²-----> equation 1
surface area of the box=area of the base+perimeter of base*height
area of the base=b²
perimeter of the base=4*b
surface area=b²+(4*b)*h------> SA=b²+4*b*h-----> equation 2
substitute equation 1 in equation 2
SA=b²+4*b*[256/b²]-----> SA=b²+1024/b-----> SA=(b³+1024)/b
the answer is
the formula of the volume of the box is V=b²*h-----> 256=b²*h
the formula of the surface area of the box are
SA=b²+4*b*h
SA=(b³+1024)/b
