Kelly is knitting a scarf for her brother. It took her 1/3 hour to knit 3/8 foot of the scarf. How fast is Kelly's knitting speed, in feet per hour?

1 1/8 feet    or 9/8 feet

Step-by-step explanation:

Kelly's knitting speed is 1 foot 1.5 inches per hour.

Step-by-step explanation:

1. Convert the fractions to decimals/numbers: 1/3 hour = 15 minutes. 3/8 of 12 is 4.5.

2. Multiply these numbers to make 1 hours worth. Remember to always multiply both numbers by the same number.

15x3=60

4.5x3=13.5

13.5= 1 foot 1.5 inches.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
