X = $20 bills
6x = $5 bills
x(20) + 6x(5) = 1450
20x + 30x = 1450
50x = 1450
x = 29
6(29)= 174
Answer:
48 cm²
Explanation:
Let the breadth be b, then the length is 3b
P = 2(Length + Breadth)
32 = 2(3b + b)
32 = 2(4b)
8b = 32
b = 4
Breadth is 4 cm
Length: 3b = 3(4) = 12 cm
Area of rectangle:
Length × Breadth
12 × 4
48 cm²
The rectangle was basically cut into two right angles so all you have to find is the length of the triangle. Using what we know which is the h<span>ypotenuse and the height, use the equation x= the square root of c^2 - a^2.
The base is x = 9.17 in</span>
The equation of the line can be shown using the slope intercept form that is
y= mx+b
where m is the slope and b is the y intercept
So firstly we have to find the value of slope m
To find the value of slope m we apply the formula
![m= \frac{( y_{2} - y_{1})}{( x_{2} - x_{1})}](https://tex.z-dn.net/?f=%20m%3D%20%5Cfrac%7B%28%20y_%7B2%7D%20-%20y_%7B1%7D%29%7D%7B%28%20x_%7B2%7D%20-%20x_%7B1%7D%29%7D%20%20)
So we can plug the values using the two given points
(-0.5,0.75) and (0.75,-0.5)
![m= \frac{(-0.5-0.75) }{(0.75-(-0.5))} = \frac{-1.25}{1.25} = -1](https://tex.z-dn.net/?f=%20m%3D%20%5Cfrac%7B%28-0.5-0.75%29%20%7D%7B%280.75-%28-0.5%29%29%7D%20%3D%20%5Cfrac%7B-1.25%7D%7B1.25%7D%20%3D%20-1%20%20)
So m = -1
Plug m=-1 in the equation we get
y= -1x +b
Now we have to find the value of b
to find the value of b , we plug any one pint in the equation
0.75 = -1(-0.5) +b
0.75 = 0.5 +b
Subtract 0.5 from both sides
0.25 = b
or
b= 0.25
Now plug the value of b , in the equation
we get
y = -1x +0.25
hence the equation of the line is y = -1x +0.25
