Answer: 2
Step-by-step explanation:
I do not think we need to rewrite the first two numbers in the given above because they are already the simplest forms of themselves being whole numbers. However, the third number may be rewritten as 1/2 by dividing both numerator and denominator by 5 and the last one as 2/25 by dividing both numerator and denominator by 4.
Answer: 2908.92435 inches.
Step-by-step explanation for shape 1: A = 2(wl + hl + hw) = 2 · (30 · 13 + 13 · 13 + 13 · 30) = 1,898 inches.
Step-by-step explanation for shape 2:
Using the formulas:
A=2AB+(a+b+c)h
AB=s(s﹣a)(s﹣b)(s﹣c)
s=a+b+c
2
Solving for A:
A=ah+bh+ch+1
2﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=9·30+13·30+9·30+1
2·﹣94+2·(9·13)2+2·(9·9)2﹣134+2·(13·9)2﹣94≈1010.92435
Step-by-step explanation for total volume: 2908.92435 inches.
The roots of x^3 - 7x^2 + 13x - 6 are 0.697, 2 and 4.303
<h3>How to determine the roots?</h3>
The expression is given as:
x^3 - 7x^2 + 13x - 6
Express as a function
f(x) = x^3 - 7x^2 + 13x - 6
Next, we plot the graph of the function f(x) (see attachment)
From the attached graph, we have the zeros to be:
x = 0.697, 2 and 4.303
Hence, the roots of x^3 - 7x^2 + 13x - 6 are 0.697, 2 and 4.303

Answer:
$13.75 , $11.25
Step-by-step explanation:
If they took off 45% of the original price, that means you gotta subtract
$25 - 45% = 13.75
to find the amount of the discount, subtract 13.75 from 25
$25-$13.75 = $11.25
