Hello :
let the slope : a and ; b the slope of the line : 5x - 3y = 8
<span>the line that is perpendicular to 5x-3y=8 so : a×b = - 1
but :
5x - 3y = 8... y = (5/3)x - 8/3 when : b = 5/3
</span><span> the slope intercept form of the equation of the line that is perpendicular
to 5x-3y=8 is : y = (5/3)x +c </span>
The feet of cloth that she should buy for the capes is 4 feet.
<h3>
How many feet should she buy?</h3>
The mathematical operations that would be used to determine the answer are addition and multiplication.
Addition is the process of summing two or more numbers together. Multiplication is the process of determining the product of two or more numbers.
The first step is to convert yard to feet
According to the unit of conversion : 1 yard = 3 feet
1 x 3 = 3 feet
The second step is to add the feet needed for Akira's cape with the foot needed for the puppy's cape

There are 7 meters in 279 inches.
- There are 2.54 centimeters in 1 inch.
- There are 100 centimeters in 1 meter.
- The number of inches is given to be 279.
- Unit conversion is a multi-step procedure that includes multiplying or dividing by a numerical factor, determining the appropriate number of significant digits, and rounding.
- First of all, we need to convert inches to centimeters.
- 1 inch equals 2.54 centimeters.
- 279 inches equals 2.54*279 centimeters.
- 279 inches equals 708.66 centimeters.
- Now, we need to convert these centimeters into meters.
- Meters in 100 centimeters = 1
- Meters in 1 centimeters = 1/100
- Meters in 708.66 centimeters = (1/100)*708.66
- Meters in 708.66 centimeters = 7.0866
- Thus, there are approximately 7 meters in 279 inches.
