A collection of 30 coins worth 5.50 consists of nickels dimes and quarters there are twice as many dimes as nickeles how many quarters are there?
Let the number of nickels, dimes and quarters be n, d, q respectively. Then n +d + q = 30 5n + 10d + 25q = 550 But d = 2n, so: n + 2n + q = 30 => 3n + q = 30 5n + 10(2n) + 25q = 550 => 25n + 25q = 550 => n + q = 22 Which gives two simultaneous equations to solve, resulting in: n = 4, q = 18 So there are 18 quarters (plus 4 nickels and 8 dimes).
What is a number n where if the sum of the digits of the number is divisible by n, then the number itself is divisible by n?
(The assumes that "the number" in the question is not n, although if they are they same number, this is still true.) "If the sum of the digits of the number is divisible by n, then the number itself is divisible by n" is true if n is 3 or if n is 9.
What is a squed number?

What is the measure of each interior angle of a regular polygon that has a total sum of 275 diagonals showing work with answer?
Let the number of sides be n and so:- If: 0.5*(n^2 -3n) = 275 Then: n^2 -3n -550 = 0 Solving the above quadratic equation: n has positive value of 25 Each interior angle: (25-2)*180/25 = 165.6 degrees
A different scaffold that weighs 300 N supports two painters one weighing 250 N and the other weighing 300 N the reading on the left scale is 400 N what should be the reading on the right scale be?
Since the total weight on the left side is 550 N (250 N + 300 N), the total weight on the right side should also be 550 N for the scaffold to be in equilibrium. Therefore, the reading on the right scale should be 150 N (550 N - 400 N) to balance the scaffold.

When two horizontal forces are exerted on a cart 750 N forward and 550 N backward the cart undergoes acceleration What additional force is needed to produce nonaccelerated motion?
To produce non-accelerated motion, the additional force needed is equal in magnitude to the resultant of the two horizontal forces. In this case, the resultant force is 750 N - 550 N = 200 N forward. Therefore, an additional force of 200 N backward is needed to achieve non-accelerated motion.
