Answer:
Answer is A $172.25
Step-by-step explanation:
Step 1: Our output value is 575.50.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$575.50=100\%$.
Step 4: Similarly, $x=30\%$.
Step 5: This results in a pair of simple equations
$575.50=100\%(1)$.
$x=30\%(2)$.
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
$\frac{575.50}{x}=\frac{100\%}{30\%}$
Step 7: Again, the reciprocal of both sides gives
$\frac{x}{575.50}=\frac{30}{100}$
$\Rightarrow x=172.65$
Therefore, $30\%$ of $575.50$ is $172.65$
Well a cylinder is the only 3 dimensional shape given so that might be it
Hey there!
3^3 + 7 ( 2(4)
3^3 = 3 × 3 × 3 = 9 × 3 = 27
27 + 7 (2(4) - 6)
2 × 4 = 8
27 + 7 × 8 - 6
8 - 6 = 2
27 + 7 × 2
7 × 2 = 14
27 + 14 = 41
Answer: 41
Good luck on your assignment and enjoy your day!
