Answer:
$81.5475 or to round it $81.55
Step-by-step explanation:
Simple steps:
1) Add the 2 items
2) Multiply by 0.75. because 25% discount = 75% of item
($72.49+$36.24)x0.75 = $81.5475 or $81.55
11. 10^-8 = 1 • 10^-8 in decimal form
12. 6 • 10^-4 = 0.0006 in decimal form
13. n^m turns into 5^4
5 • 5 • 5 • 5 = 625
5^4 = 625
6.21 --subtract 1.05 from 7.26
Answer:
216 cm²
Step-by-step explanation:
Applying,
V = lwh..................... Equation 1
Where V = volume of the cubiod, l = length of the base, width of the base, h = heigth of the cubiod.
From the question,
Since the base of the cubiod is squared,
Therefore,
w = l = 4 cm, V = 400 cm³
Substitute these values into equation 1
400 = 4×4×h
h = 400/(4×4)
h = 25 cm
A = lw+lh+wh.................. Equation 1
Where A = surface area of the cuboid.
Given: l = 4 cm. w = 4 cm, h = 25 cm
Substitute these values into equation 1
A = (4×4)+(4×25)+(4×25)
A = 16+100+100
A = 216 cm²
