Let's call Kenny's weight K, Melvin's weight M.
We know that K=6/7*M hence K/M=6/7
We can write multiple equations that have the same solution.
Two of these equations could be for example:
Equation 1:
10x = 12
Equation 2:
2x-1 = 1.4
Note: when clearing x in both equations we have:
x = 1.2
Answer:
10x = 12
2x-1 = 1.4
1/4 is equal to 4/16 so the answer would be B. 4
To solve this you can multiply the denominator and numerator by the same number to get an equivalent fraction. In this case you would divide the denominator of the equivalent fraction we are finding the numerator for (16) by the denominator of the original faction.
?/16 / 4 16/4 = 4
The numerator is 4 making the equivalent fraction 4/16.
Hope this helps!
Both by Pythagorean theorem and dot product approaches, we find that the magnitude of the vector <u>u</u> = <4, 7> is equal to √65.
<h3>What is the magnitude of a vector?</h3>
Vectors are characterized by two elements: Magnitude and direction, the magnitude is a scalar that represents the <em>"length"</em> of the vector, while the direction indicate the <em>"orientation"</em> of the vector. There are two methods to find the magnitude of the vector u:
Method 1 - Pythagorean theorem
<u>u</u> = <4, 7>
u = √(4² + 7²)
u = √65
Method 2 - Dot product
<u>u</u> = <4, 7>
u = √(u • u)
u = √[(4, 7) • (4, 7)]
u = √(4² + 7²)
u = √65
Both by Pythagorean theorem and dot product approaches, we find that the magnitude of the vector <u>u</u> = <4, 7> is equal to √65.
