Answer: nickels = 14, dimes = 42, quarters = 18
<u>Step-by-step explanation:</u>
Let n represent nickels <em>which has a value of $0.05 </em>
Let d represent dimes <em>which has a value of $0.10</em>
Let q represent quarters <em>which has a value of $0.25</em>
It is given that:
n = n
d = 3n
q = n + 4
and their total value is $9.40 ⇒ n + d + q = $9.40
Use substitution to find the quantity of nickels:
.05(n) + .10(3n) + .25(n + 4) = 9.40
5n + 10(3n) + 25(n+4) = 940 <em>multiplied by 100 </em>
5n + 30n + 25n + 100 = 940 <em>distributed</em>
60n + 100 = 940 <em>added like terms</em>
60n = 840 <em>subtracted 100</em>
n = 14 <em>divided by 60</em>
n = 14
d = 3n
= 3(14)
= 42
q = n + 4
= (14) + 4
= 18
Volume of the right triangular prism 90 cube cm.
Step-by-step explanation:
Given,
In the right triangular prism
Length (l) = 6 cm
Base (b) = 5 cm
Height (h) = 6 cm
To find the volume of the right triangular prism
Formula
Volume of the right triangular prism = bhl
Now,
Volume of the right triangular prism = ×6×6×5 cube cm
= 90 cube cm
Well, for a line with a slope of 3/4, any other parallel line to it, will also have the same slope of 3/4
so if the line through (2, -1) is parallel to it, it has a slope of 3/4 as well
