Answer: 4
<u>Step-by-step explanation:</u>
Inversely proportional means xy = k, where k is the constant of proportionality
First, find k when x = 2 and y = 400 ----> 2(400) = k --> 800 = k
Then, find y when x = 200 (knowing that k = 800)
200y = 800
y = 4
Constants are numbers alone with no variables.
The constants are: 12, -3.7, 1/3
Answer: A = b x h/2
15/32 or .46875 (sorry if im wrong,i tried)
Step-by-step explanation:
Answer:
x = 20/49 units; P = 8 48/49 units
Step-by-step explanation:
All sides of a square are congruent.
That means that the two given side lengths are equal.
We set the two lengths equal and solve the equation for x.
5.5x = (1/5)(3x + 10)
Multiply both sides by 5.
27.5x = 3x + 10
Subtract 3x from both sides.
24.5x = 10
x = 10/24.5
x = 20/49
The perimeter of a square is 4s, where s is the length of a side.
P = 4s
= 4(5.5x)
= 4 * 5.5 * 20/49
= 22 * 20/49
= 440/49
= 8 48/49
Answer: x = 20/49 units; P = 8 48/49 units
Answer:
12 seconds.
Step-by-step explanation:
Let t represent time taken by code to sort an array of 24 elements.
We have been given that an algorithm takes 4 seconds to sort an array of 8 elements. We are asked to find the time it will take for same code to sort an array of 24 elements.
We will use proportions to solve our given problem.
Therefore, it will take 12 seconds for the same code to sort an array of 24 elements.
