$1.90
Represent the numbers of nickels, dimes and quarters by n, d and q.
Then: d + q = 9, or q = 9 - d.
Also, n + d = 10
Lastly, n + d + q = 15.
Let's substitute 9 - d for q in the equation immediately above:
n + d + (9 - d) = 15, or n + 9 = 15. Then n must be 6.
In summary, Jim has 6 nickels, (10 - 6) dimes and (9 - 4) quarters, or:
6 nickels, 4 dimes and 5 quarters
Thus, he has 5($0.05) + 4($0.10) + 5($0.25), or
$0.25 + $0.40 + $1.25, or $1.90
(-6, 6)
The coordinates of B to start with is
(-2, 2)
To dilate this by a factor of 3....
-2 * 3 = -6
2 * 3 = 6
The new coordinates of B' would be
A few things to know:
- The number 3 is called a "<u>scale factor</u>"
- Dilation means we are multiplying all the (X, Y)'s by the scale factor
- If the scale factor is <u>greater than 1</u>, the size of the shape overall increases
- If the scale factor is <u>less than 1</u>, the size of the shape overall decreases
- If the scale factor is <u>negative</u>, the shape size stays the same. The shape just rotates 180 degrees and moves to the opposite quadrant.
