Answer:
34.7857142857
Step-by-step explanation:
We meet again
so first divide 60 by 5
this gives 12
then multiply 12 by 4
giving a final answer of 48
Question #1:
a)
(4, 2)
Both of these are positive, and when x and y are both positive they're both in Quadrant 1.
b)
(x + 1, y - 5)
Add 1 to 'x', subtract 5 from 'y':
(4 + 1, 2 - 5)
(5, -3)
x is positive and y is negative, that means this will be in Quadrant 4.
c)
Reflection Across y-axis:
(-x, y)
Multiply -1 to 'x':
(5 * -1, -3)
(-5, -3)
Both of these are negative, if both x and y are negative it's located in Quadrant 3.
Question #2:
No, that can't tessellate a plane. We can't cover up space so there are no overlaps or gaps.
Answer:
Let the proportion of the $0.20 be x
Then the proportion of the $0.68 is 1−x
Set the target at $0.54
Dropping the unit of measurement ($ ) for now we have
0.20x+(1−x)0.68=1×0.54
0.20x−0.68x+0.68=0.54
−0.48x+0.68=0.54
Lets get rid of the decimals for now and multiply everything by 100
−48x+68=54
48x=68−54
x=1448
x=724 of the blend at $0.20
So the proportion of the $0.68 is 1−724=1724
