Answer:
Below
Step-by-step explanation:
1 pound = 16 ounces
Therefore if you're looking for 8 ounces, divide $7.50 in half.
You get $3.75
7,24,25 ~ x,72,75
so x/7 = 72/24 = 75/25 = 3
then x = 7*3 = 21
Here’s what you can do to make this very simple. Consider that the “missing” space between the rectangles isn’t there. Then, find the area:
10 x 9 = 90 mm
Now, find the area of the “missing” part.
5 x 2 = 10 mm
Finally, you deduct the missing part from the complete rectangle!
90 - 10 = 80 mm
The area of this whole thing is 80 mm!
It is a geometric sequience.
the general term (an) is:
an=a₁*r^(n-1)
a₁ is the first term=2
r=the common ratio=a₂ / a₁=4/2=2
therefore:
an=2*2^(n-1)
an=2^(n-1)+1
an=2^n
solution: an=2^n
To check
a₁=2¹=2
a₂=2²=2*2=4
a₃=2³=2*2*2=8
a₄=2⁴=2*2*2*2=16 ....
