Answer: 176in
Step-by-step explanation:
44*4= 176
multiply length and width
Answer:
219 + 159 <= x <= 369 + 309
378 <= x <= 678
Step-by-step explanation:
Answer:
the new frame is bigger than the original frame by 10%
Step-by-step explanation:
Let the length of the original frame be l,
then it's width is (10% of l)=
×l
=
hence area of original frame=A=length×width
=
now the length of frame is enlarged by 10%
new lenght of frame=l+10%×l
=l+
×l
=
×l
width of new frame==
area of new frame=length×width
=
percent change=((area of new frame-area of old frame)×100)÷area of old frame
=10%
Let x be the value of the third term.
Since it's a geometric sequence, then:
Third term/Second term = Fourth term/Third term
x/20 = 11.25/x
Cross multiplication:
x^2 = 225
x = 15
So since the ratio is constant, then it is
x/20 = 15/20 = 3/4
So the common ratio is 3/4 or 0.75.
