The length of his neck is longer than the length of his forearms by 44.86 %.
<h3>Calculations and Parameters:</h3>
Given:
Length of his neck = 14.72 inches
Length of his forearm = 25.81 cm
We know that:
1 inch = 2.54 cm
So, 14.72 inches = 14.72×2.54
=37.39 cm
So, the Length of his neck becomes 37.39 cm
So, the length of his neck is longer than the length of his forearms.
The difference between them is given by
37.39-25.81
=11.58 cm
so, the Percentage of change would be
11.58/25.81 * 100
=44.86%

Answer:
i belive it was 750.
Step-by-step explanation:
Answer:
Rate of change of the area of the square is 42 units at t = 2.
Step-by-step explanation:
We note that the area of the square is given by: 
but we aim to find 
. But we can use the chain rule to pull out that dA/dt. Doing so gives us:
Now, 
(by the power rule and 
But since we have "x" and not "t", we want to find what x is when t = 2. Substituting t = 2 gives us x(2) = 3(2) + 1 = 7.
So, finally, we see that:
Answer:Number of children = 2 and number of adults = 9 attended the play
Step-by-step explanation:
Step 1
Let the number of children be represented as x
and the number of adults in the group be represented as as y
such that the total number of the group that went to the play
= x+y=11--- equation 1
And the total cost paid for the play will be expressed as
15x+ 22y= 228------ equation 2
Step 2-- Solving
x+y=11--- equation 1
15x+ 22y= 228------ equation 2
B y elimination method, multiply equation 1 by 15 to give equation 3 and then subtract from equation 2
15x+ 22y= 228------ equation 2
15x+15Y= 165----- equation 3
7y=63
y= 63/7= 9
y= adults = 9
therefore x = number of children will be
x+y=11
x+ 9=11
x= 11-9= 2
In the group that attended the play, Number of children = 2 and number of adults = 9
