The answer would be (x,y) —> (x-1,y). the reasoning being that all of the points on the x axis move to the left by one unit, and all points on the y axis stay the same.
<u>Find cost of a ticket:</u>
40% = $5.00
1% = $5 ÷ 40 = 0.125
100% = 0.125 x 100 = $12.50
The cost of a ticket is $12.50
<u>Find 20% of two tickets:</u>
Two tickets cost $12.50 x 2 = $25
20% of $25 = 0.25 x $25 = $5
Answer: 20% of two tickets cost $5
The answer is B
Because if you use your calculation right you would end up with 16,463
Answer:
Width = 16(√5) - 1
Step-by-step explanation:
We are told that the golden rectangle is 32 cm long.
Thus, length = 32 cm
We are also told that the ratio of the length to the width is; (1 + √5):2
Thus;
If a length of (1 + √5) yields a width of 2
Then, a length of 32 cm would yield a width of; (32 x 2)/(1 + √5)
So corresponding width = 64/(1 + √5)
We want to reduce this width to it's simplest radical form which means the denominator should have no square root.
Thus, let's multiply top and bottom by (1 - √5);
Width = 64 x (1 - √5)/[(1 + √5) x (1 - √5)]
Width = 64(1 - √5)/(1 - 5)
Width = 64(1 - √5)/(-4)
Width = -16(1 - √5)
Width = 16(√5 - 1)
Width = 16√5 - 1
