Divide both by 18.
<span>140/18=7.78 </span>
<span>So... $7.78 per foot</span>
Equation 1 = 8
equation 2 = 8
equation 3 = 8
equation 4 = 6
so it’s 4 :)
Time taken to fill the bathtub is 8 min
time taken to drain the bathtub is 12 min
fraction of bathtub filled in 1 hour=1/8
fraction of bathtub drained in 1 hour=1/12
fraction that will be filled in a minute given that both taps are opened at he same time:
1/8-1/12
=1/24
thus time taken for the bathtub to be filled is 24 min
Answer:
this doesnt make sense as a question
To calculate the surface aarea, we will use the formula;
T.S.A = 1/2 (pl) + B
where;
p= perimeter of the base
l= slant height
B= area of the base
From the diagram
l= 10 yard
P= 4(16) = 64 yard
B= 16 x 16= 256 yards
Substitute the value into the formula;
T.S.A = 1/2 (64)(10) + 256
=320 + 256
=576 inches²
