Answer:
the gradient is -5/1 or -5 because it is a negative slope meaning you would go from top to bottom.

Let the length be x
Area = x²
Perimeter = 4x
<span>Area of a square is 3 times its perimeter
</span>⇒ x² = 3(4x)
x² = 3(4x)
x² = 12x
x² - 12x = 0
x(x - 12) = 0
x = 0 or x = 12
Since x cannot be zero, x = 12
Answer: The length is 12 units.
Well if there were 50 questions it would be 2 points each so if he ended up with 96% he must have missed 2 questions
Answer:
a) 375
b) 7062.75 mm²
Step-by-step explanation:
b) We need to find the shortest possible width and length to get the smallest possible area.
To get the boundaries for 19.4, we go on to the next significant figure (the hundredths) and ± 5 of them.
The boundaries are, therefore: 19.35 - 19.45
As for the length, we can see they've added 5 units as the measurement is correct to 2 sig' figures, which is the tens.
And so, if we do as we did before, we go to the next sig' figure (the units) and ± 5 of them, we get the boundaries to be 365 - 375.
Now, we just multiply the lower bounds of the length and width to get the minimal/lower-bound area:
365 * 19.35 = 7062.75 mm²
135 degrees is your answer
