Answer:
Step-by-step explanation:
Ratio of length : width = 4 : 7
Length = 4x
Width = 7x
Longer side = 31.5 in
⇒ 7x = 31.5
Divide both sides by 7
x = 31.5/7
x = 4.5
length = 4x
= 4*4.5
l = 18 in
width = 31.5
w = 31.5 in

= 2*18 + 2*31.5
= 36 + 63
= 99 in

= 18*31.5
= 567 in²

Answer:
-2
Step-by-step explanation:
The slope of a line is given by
m = (y2-y1)/(x2-x1)
= (-3 -5)/(2- -2)
= -8/(2+2)
-8/4
-2

Given that,
Michael is leaving a 15% tip for his waitress.
To find,
What percent of the original price will he pay.

or

So, this is the required solution.
