Answer:
Find the 40th term for the arithmetic sequence in which
a8=60 and a12=48 .
Substitute 60 for a8 and 48 for a12 in the formula
an=a1+(n−1)d to obtain a system of linear equations in terms of a1 and d .
a8=a1+(8−1)d→60=a1+7da12=a1+(12−1)d→48=a1+11d
Subtract the second equation from the first equation and solve for d .
12=−4d−3=d
Then 60=a1+7(−3) . Solve for a .
60=a1−2181=a1
Now use the formula to find a40 .
a40=81+39(−3)=81−117=−36 .

II. Find the area of the ahaded region.
1. Area of the entire parallelogram- 64 in2
2. Area of rectangle in the middle- 12 in2
3. 64 - 12 = 52 in2
10)
1. 18 cm2
2. 4.5 cm2
3. 18 - 4.5 = 13.5 cm2
13)
Area= Base x Height
Area= 9 x 8
Area= 72 ft2
14)
Area= 1/2 height (base1 + base2)
Area= 1/2 x 24 x (30 + 28)
Area= 696 in2

A financial plan is an evaluation of an investors current and future financial state by using currently known variables to predict future cash flows asset values and withdrawal plans.
Answer:
1:3
Step-by-step explanation:
3:12 is the amount of shaded circles to all circles, 8:2 is basically the same thing as 3:12 and 9:3 is the amount of shaded circles to the amount of non-shaded circles. 1:3 wouldn't work because it is not the right ratio.
