Answer:
D. $680
Step By Step Explanation:
100 pages are typed. Each page coast $5 to type.
100 x 5 = 500
40 pages are revised once. It costs $3 to revise a page once.
40 x 3 = 120
10 pages are revised twice. It costs $3 to revise a page once so it will cost $6 to revise it twice
10 x 6 = 60
To find the total cost we add all the amounts together
500 + 120 + 60 = 680
The final answer is $680
<span>3 - (2 - 8)
= 3 - 2 + 8
= 11 - 2
= 9
In short, Your Answer would be Option B
Hope this helps!</span>
I’m pretty sure it’s, D, if not, it’s C, I haven’t done this in a few years so correct me if I’m wrong, but I’m more sure it’s D.
Answer:
side length of sculpture = 9 cm
height of sculpture = 6cm
Step-by-step explanation:
Given that,
volume of sculpture = 162cm³
side length of sculpture = x
height of sculpture = x-3
formula for volume of sculpture
<h3>V=1/3 a²h</h3>
by putting values, the equation can be used to find the length of the sculpture’s base
162 = 1/3 (x)² (x-3)
162(3) = (x)² (x-3)
486 = x²(x-3)
486 = x³ - 3x²
x³ - 3x² - 486 = 0
x = 9 <em>(using a graph tool / calculator equation mode)</em>
side length of sculpture = 9 cm
height of sculpture = 9 - 3
= 6cm
