Answer:
a) 1/4 minute
Step-by-step explanation:
You can find the time using a proportion. It took 5 minutes to drain the entire 360 liters, so we can write the proportion as ...
time/volume = (5 min)/(360 L) = t/(18 L)
Multiplying by 18 L gives ...
t = (18/360)(5 min) = (5/20) min = 1/4 min
It took 1/4 minute to drain each 18 liters.
Answer:
y=13
Step-by-step explanation:
if x=20 when y=8 (we can creat equation )
x=2y+4 (you can prove that the equation is correct by substitute )
so the question is if x=30 find the value of y
30=2y+4
30‒4=2y
26=2y
26/2=2y/2
13=y

Answer: <em>6 units</em>
Step-by-step explanation:
<em>Area = 1/2 (base1 + base2) X height <-------- Formula for a trapezoid</em>
<em>24 = 1/2 (2 + 6) X h <----- We know that the area of the trapezoid is 24 units </em>
<em>squared and that both of the bases are 2 units and 6 units. </em>
<em>24 = 1/2 (8) X h <------- Add 6 + 2</em>
<em>24 = 4 X h <----- Half of 8 is 4</em>
<em>h = 6 <------ 6 X 4 = 24 , therefore the height is 6 units.</em>
