Answer:
the side length is 30 feet
Step-by-step explanation:
we are given cost equation as
where
C is the cost in dollars
n is a side length in feet
we are given
cost is $355
so, C=355
we can set C=355
and then we can solve for n
we can subtract both sides by 175
Multiply both sides by 5
now, we can take sqrt both sides
So,
the side length is 30 feet
They provide all the needed data...
n + d + q = $3.00 (they provide a ratio)
3:2:1 = $3.00 (let's enter the value of each)
3(.05) + 2(.10) + 1(.25)
.15 + .20 + .25
.60 = is the value of the ratio
let's divide the $3.00 by the .60 to get 5
let's now multiply the value of 5 to the ratio and solve the question...
3(5): 2(5): 1(5)
15 nickels
10 dimes
5 quarters
Answer:
$27
Step-by-step explanation:
$45 * .40 (same thing as 40%)
$45 * .40 = 18 (this is how much 40% of $45 is)
$45 - 18 = $27 (you subtract 18 because it’s 40% off)
$27 (final answer)
