2 = 8 / 4
8 / 4 - 1 / 4 = 7 / 4
They ate 7/4 lbs, or 1.75 lbs.
Ok, so
Length = L
Width = L + 7
Since area = length x width, then
30 = L × (L + 7)
Remember that L + 7 Is width so...
L + 7 = 30/L
So the expression for the width in terms of length would be...
w = 30/L - 7
The problem is modelled as right angle triangle, shown in the diagram below
The distance between the pilot and the house is labelled as

Using the trigonometry ratio of sine


Since it is a geometric sequence each term will be a specific multiple of the term preceding it, called the common ratio...
126/42=378/126=1134/378=3
The sequence is a(n)=a(3)^(n-1) and we know the second term is 42 so:
42=a(3)^(2-1)
42=3a
a=14
So the first term is 14.
Answer:
Step-by-step explanation:
We know she gets 4 more quarters so: q+4
She gives away 3 dime so: d-3
And the nickels stay the same: n
In total the expression would be: <u>q+4+d-3+n</u>
