Answer:
$17.43
Step-by-step explanation:
30% of 24.9 is 7.47, subtract 7.47 from 24.9 and you get 17.43
10³ = 1 000
17.55 x 1 000 = 17550
Answer:
102cm²
Step-by-step explanation:
Surface Area = BH +Lp
B is the base area
H is the height of the Prism
L is the slant height
p is t perimeter of its base
B =1/2 ×3×4
B= 6cm²
H = 7cm
L = 5cm
P = 3cm+4cm+5cm
P = 12cm
Substitute
TSA = 6(7)+5(12)
TSA = 42+60
TSA = 102cm²
Hence the total surface area of the shape is 102cm²
A=1 b=1 c=- 4 correct answer
