Answer:
40%
Step-by-step explanation:
According to the given description of the 10 by 10 grid, 40 out of 100 squares are shaded.
Convert into a Fraction:
Convert the fraction into a decimal:
Convert the decimal into a percent:
<u>40%</u>
<u></u>
So, the grid should represent 40%.

BC is 3 across & CA is 3 up, but this creates a right-angle triangle. So, Pythagoras Theorem is used to find AB
AB = root 3^2 + 3^2
AB = 3 root 2
or 4.242640687
Thus, AB is 4.24 to 2d.p
(root means square root)
Hope this helps!
Answer:
False
Step-by-step explanation:
All squares are rhombuses, but not all rhombuses are squares
Answer:
x = 59°
y = 130°
Step-by-step explanation:
Find x:
Recall: the measure of an inscribed angle = ½(measure of intercepted arc), based in the inscribed angles theorem
Therefore,
x = ½(118°)
x = 59°
Find y:
y = 2(180 - (56 + x)) => inscribed angles theorem
Plug in the value of x
y = 2(180 - (56 + 59))
y = 2(180 - 115)
y = 2(65)
y = 130°
For this case we have the following inequality:
We must evaluate each of the points and verify if the inequality is met:
The inequality is met!
It is not fulfilled!
It is not fulfilled!
Thus, the point that meets the inequality is (6,2)
