Length = L
New length = L+0.1L= 1.1 L
Width = W
New width = W - (W/100)p= W-pW/100= (100W-pW)/100=W(100-p)/100
Area =A = LW
New area = A - 0.12A = 0.88A
New area = new width*new length = 1.1L*W(100-p)/100 = 1.1A(100-p)/100
New area = 0.88A
New area = 1.1A(100-p)/100
1.1A(100-p)/100 = 0.88A
1.1(100-p)/100 = 0.88
1.1(100 - p) = 88
100 - p = 80
p = 20
Answer C) 20.

Answer:
129
Step-by-step explanation:
for this one they gave us to angles and if you didnt know those angles are supplementary so they are going to add up to equal 180 so first things first is we want to find the value of x, to do that we do
180=x+19+4x+1
step 1 combine like terms
4x+x=5x
19+1=20
now we have
180=20+5x
step 2 subtract each side by 20
20-20 cancels out
180-20=160
now we have
160=5x
step 3 divide each side by 5
5/5 cancels out
160/5 = 32
x=32
now we want to plug in 32 for each expression to find which one is greater
(32)+19=51
4(32)=128
128+1=129
so the answer is 129
hope this helps :D
Answer:
<em>"Consecutive y-values change by multiplying previous value by a constant amount. So, the table represents an exponential function."</em>
Step-by-step explanation:
In reality, the table represents an exponential function instead of a linear function, since values on domain change arithmetically at constant rate, whereas values on range change geometrically at constant rate.
Correct phrase may be:<em> "Consecutive y-values change by multiplying previous value by a constant amount. So, the table represents an exponential function."</em>
