Answer/Step-by-step explanation:
Part A: Net A is the correct net. If we decide to fold the net, we'd get the shape of the prism. Folding back net B won't give us the shape of the prism because of the position and arrangement of the right triangular bases.
Part B:
AB = 3in
BC = 5 in
CD = 9.4 in
Part C: surface area of the prism can be calculated by calculating the area of each part of the net, and summing them together as follows,
Area of the 2 triangular bases = 2(½*base*height of triangle) = 2(½*4*3) = 2*2*3 = 12 in²
Area of the three rectangles =
Surface area of prism = 12 + 112.8 = 124.8 in²
Answer: 7638373
Step-by-step explanation:
Answer:
With distribution
-2(3) + -2(-4) + -2(-8) + -2(7)
= -6 + 8 + 16 - 14
= 4
Without distribution
-2 (3 -4 -8 + 7)
= -2 (-2)
= 4
23, 24, 25
23+24+27 equals 72
Answer:
$46.83
Step-by-step explanation:
The standard formula for compound interest is given as;
A = P(1+r/n)^(nt) .....1
Where;
A = final amount/value
P = initial amount/value (principal)
r = rate yearly
n = number of times compounded yearly.
t = time of investment in years
For saving account A;
P = $1,800
t = 2 years
n = 12 (monthly
r = 3.6% = 0.036
Substituting the values;
A = 1800(1+0.036/12)^(12×2)
A1 = $1934.17
for saving account B;
P = $1,800
t = 2 years
n = 12 (monthly
r = 4.8% = 0.048
Substituting the values;
A = 1800(1+0.048/12)^(12×2)
A2 = $1981.00
The difference will then be
d = A2 - A1
d = $1981.00 - $1934.17
d = $46.83
Therefore, she would have $46.83 more
