Answer:
m = 
Step-by-step explanation:
Lets start with finding the volume of the pool
The formula for the volume of a rectangular prism is
V=l*w*h where l=length w=width and h=height
plug in the data we know
V=40*20*4
V=3200ft³
Now for the hot tub.
3200ft³*1/4=800ft³
Add the volumes together
3200+800=4000ft³
Answer=4000ft³
Answer:
may be 30 is the cube root of 27000
Step-by-step explanation:
just do a claculation
Answer:
The gradient is 0.500
Step-by-step explanation:
Directly means when x goes up by 3 then y goes up by 3
it is represented by
y/x=k where k stay the same
so y=-21
x=3
the equation is -21/3=-7
k=-7
so k =-7
therfor
y/x=-7
then manipulate the equation
multiply boht sides by x
y=-7x
subsitute valuse for x and get values for y
if (x,y)
(1,-7)
(2,-14)
(3,-21)
so posiible equationscould be
-7/1=-7
-14/2=-7
-21/3=-7
and so on
