Hope this helps. You should transfer them into fractions, change to common dominators. then subtract and then you get your final answer, you may reduce it from there or not.
Answer:
Jada and lin are comparing inches and feet.
Let I denote inches and F denote feet.
It is given that
I =k F or F=m I
So, I/F=k or m=F/I
As we know 1 feet = 12 inches
constant of proportionality i.e k=1/12
In case 2, constant of proportionality=12/1=12
So, Jada must have calculated ratio of feet to inches while Lin has calculated the ratio of inches to feet.
Step-by-step explanation:
The converse of the Pythagorean Theorem is: If the square of the length of the longest side of a triangle is equal to the sum of the squares of the other two sides, then the triangle is a right triangle. That is, in ΔABC, if c2=a2+b2 then ∠C is a right triangle, ΔPQR being the right angle.
Answer:
3/4 or 0.75

I don’t get all the other stuff but 1/4 + 1/2 = 3/4
Answer:
315 chocolate
Step-by-step explanation:
Let Sam's chocolate be S
Let Clariss's chocolate be C
When Sam gave Clarissa 105 chocolates, Clarissa had 5 times as many chocolates as Sam.
This can be written as:
C = 5S
The sum of their chocolate is 504 i.e
S + C = 504
Now, let us determine the chocolate of Clarissa after receiving 105 chocolate from Sam. This can be obtained as follow:
S + C = 504
But: C = 5S
S + 5S = 504
6S = 504
Divide both side by 6
S = 504/6
S = 84.
C = 5S = 5 x 84 = 420
Therefore, Clarissa have 420 chocolate after receiving 105 chocolate from Sam.
Now, to know the amount of chocolate that Clarissa has at first, we simply subtract 105 from the present amount that Clarissa have. This is illustrated below:
Amount of chocolate that Clarissa has a first = 420 – 105 = 315
Therefore, Clarissa had 315 chocolate at first.
