0.09x+0.06 (2500-x)=171
solve for x
0.09x+150-0.06x=171
0.03x+150=171
0.03x=171-150
0.03x=21
X=21÷0.03
X=700 invested at 9%
2500-700=1800 invested at 6%
Hope it helps!
Formula for sufrace area of rectangular prisms: S= 2 (lw + lh + wh)
for the first prism, x=14, plug 14 into 2(x)--> 2(14)=28
7,8,28
S= 2 [7(8)+7(28)+8(28)]
S= 2 (28+196+224)
S= 2(448)
S= 896
for the second prism, x is just 14
7,8,14
S= 2 [7(8)+7(14)+8(14)]
S= 2 (28+98+112)
S= 2(238)
S= 476
Add the two sufrace areas we found and the answer will be
D) S= 1,372
Answer:V/H=I
Step-by-step explanation:
v=IH
V/H=I
Her change will be $16.22 since 20 +20 is 40 and 40 - 23.78 is 16.22
16500 Rounded to the nearest ten thousand is 20,000
