Answer:97/12 + (-4 1/3) = 15/4
Step-by-step explanation:
15/4 - (-4 1/3) = 97/12
97/12 + (-4 1/3) = 15/4
Answer:
Step-by-step explanation:
1. Look a lowest common denominator
2. Divide 12 by 4 and 12 itself as it is the lowest common denominator,,multiply the quotients by there respective numeraters as in the picture
3. Add,,,then simplyfy
Answer:
- height: 9 chi 6 cun
- width: 2 chi 8 cun
Step-by-step explanation:
The factor-of-ten relationship between the different units means we can combine the numbers in decimal fashion. If 1 unit is 1 zhang, then 1 chi is 0.1 zhang and 1 cun is 0.01 zhang. Hence 6 chi 8 cun is 0.68 zhang.
Let x and y represent the width and height, respectively. In terms of zhang, we have ...
y - x = 0.68
x^2 +y^2 = 1^2
Substituting y = 0.68 +x into the second equation gives ...
x^2 + (x +0.68)^2 = 1
2x^2 +1.36x - 0.5376 = 0 . . . . . eliminate parentheses, subtract 1
Using the quadratic formula, we have ...
x = (-1.36 ±√(1.36^2 -4(2)(-0.5376)))/(2·2) = (-1.36 ±√6.1504)/4
x = 0.28 . . . . . the negative root is of no interest
y = 0.28 +0.68 = 0.96
In units of chi and cun, the dimensions are ...
height: 9 chi 6 cun
width: 2 chi 8 cun
I am not positive but I think it is 2.617. I hope that helps
Answer:
y= 3x+10.
Step by step explanation:
To find this, we will need to use the points from the center and a corner of the rectangle. We can find the slope by using the slope formula:
We get a value of m=3.
Now, use one of these points and substitute it into the equation 'y=mx+b', giving us:
7= 3(-1)+b
7=-3+b
10=b
Finally, we get our equation y=3x+10.
