Answer:
11.7 cm
Step-by-step explanation:
Using Pythagoras Theorem
AC² = AB² + BC²
AB = 4 cm
BC = 11 cm
AC² = 4² + 11²
AC = √4² + 11²
AC =✓137
AC = 11.704699911 cm
Approximately = 11.7 cm
Length AC = 11.7cm
Answer:
k = 2
x = 2y
Step-by-step explanation:
If variables x and y vary directly, this is expressed as;
x ∝ y
x = ky
k is the proportionality constant
Let's assume the value of x and y since we are not given;
x = 20
y = 10
Substitute
20 = k(10)
10k = 20
k = 20/10
k = 2
Hence the constant of proportionality is 2
Substitute i=k = 2 into the equation x = ky
x = 2y
Hence an equation that relates x and y is x = 2y
<em>Note that the values here are assumed value, you can use the same method for any values of x and y</em>
Well, sum means adding. So adding it all together, I got 2.83 with the 3 repeating
Answer:
Step-by-step explanation:
The Pythagorean Theorem is incredibly useful. It states that
(Refer to the image labeled diagram 1). C is the hypotenuse of the triangle, or the longest side. It is always opposite of the right angle in the triangle. a and b are the other two sides, in no specific order. I attached 2 examples.
Hope it helps <3
If Sharon is 3 years younger, then it's s = 3-b. However, it's twice her brothers age, which makes the formula our final answer, A, or ![s = 3 - 2b](https://tex.z-dn.net/?f=s%20%3D%203%20-%202b)
