Solution: Let x be the amount to be invested (15%).
Then,
x*0.15 + 550*0.11 = (x+550)*0.12
x*0.15 - x*0.12 = 550*0.12 - 550*0.11
0.03x = 550*(0.12-0.11)
0.03x = 550*0.01
0.03x = 5.5
x =5.5÷0.03
x=183.33
Answer: $183.33 more to be invested for 12 % total return.
Answer:
660000
Step-by-step explanation:
7sqrt = 49 since the base is a square.
49 x 2 = 98 - since there's 2 of those identical squares.
7 x 5 = 35 - area of the rectangular face.
35 x 4 = 140 - since there's 4 of those faces.
140 added by 98 is 238.
So answer is B.

Answer:
Step-by-step explanation:
Looking at the given graph, the slope of the line is expressed as
Slope = (y2 - y1)/(x2 - x1)
y2 = 19.5
y1 = 9.5
x2 = 6
x1 = 1
Slope = (19.5 - 9.5)/(6-1)
Slope = 10/5 = 2
The successive terms is increasing by 2
The formula for the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a is the first term of the sequence
n is the number of terms in the sequence.
d is the common difference.
From the information given,
a = 9.5
Tn = an
d = 2
The explicit rule for the arithmetic sequence will be
an = 9.5 + 2(n-1)
