Well the formula:
V = Bh
54= 3*w*8
54= 24w
24w=54
w= 54/24
w= 2.25
Answer:
E. 800%
Step-by-step explanation:
Since,
u = 8d/h² __________ eqn (1)
Now, density (d) is doubled and usage (h) is halved.
Hence the new life (u'), becomes:
u' = 8(2d)/(0.5h)²
u' = 8(8d/h²)
using eqn (1), we get:
u' = 8u
In percentage,
u' = 800% of u
In words, the percentage increase in useful life of the equipment is <u>800%</u>.
Since it is 2 shirts
15 times 2 = 30
30% of off 30 dollars is 21 dollars
7% tax increase will come to 22.47
The total cost should be $22.47
.3 / .5 = .6
.3 is the dividend
.5 is the divisor
.6 is the quotient
