Answer:
184 cm²
Step-by-step explanation:
Surface area of the rectangular box is expressed as S = 2(LW+LH+WH)
L is the length of the box = 90 cm
W is the width of the box = 50 cm
H is the height of the box= 90 cm
If there are error of at most 0.2 cm in each measurement, then the total surface area using differential estimate will be expressed as shown;
S = 2{(LdW+WdL) + (LdH+HdL) + (WdH+HdW)
Note that dL = dW = dH = 0.2 cm
Substituting the given values into the formula to estimate the maximum error in calculating the surface area of the box
S = 2{(90(0.2)+50(0.2)) + (90(0.2)+90(0.2)) + (50(0.2)+90(0.2))
S = 2{18+10+18+18+10+18}
S = 2(92)
S = 184 cm²
Hence, the maximum error in calculating the surface area of the box is 184cm²

as
15²=12²+9²(using Pythagoras theorem)
or
225= 144+81
225=225
(the Pythagorean theorem, also known as Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. )
Answer:

c) (-00,-3]
Please help me bro i have exam!
Answer:
Its equal; well specify what "first hours" means but, here we go.
Step-by-step explanation:
Assuming that the first hours are the 8 hours, multiply 8 by 5 to get $40
Main Deck charges $18 for 4 hours which multiplied by 2 will be $36. Then 2x2=4. $4 per hour after that. With a grand total of $40
Let me know if I'm wrong, I'm trying to improve as I go!
Answer:
$5.13
Step-by-step explanation:
So, <em>s</em> = $5.00.
OG Price * 1.0<em>a</em> = Total (that is the expression)
5.00 * 1.0250) = 5.125* = $5.13
<em>a</em> is the percentage of markup with no decimal!
) = I don't think you need the 0, but just in case!
* (at end)= round!
