Answer:
C) All squares are rhombuses. Rhombeses have 4 sides that are the same length. Therefore, all squares have 4 sides that are the same length.

Hope it helps.
Step-by-step explanation:
An arc of a circle is a "portion" of the circumference of the circle. The length of an arc is simply the length of its "portion" of the circumference. The circumference itself can be considered a full circle arc length. ... the angle subtends, s, divided by the radius of the circle, r.
Answer:
y = 0.5x
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 1, y = 0.5, then
k = 
= 
= 0.5, hence
y = 0.5x ← equation of variation
Answer:
6.23*10^6
Step-by-step explanation:
We first write the answer in full notation 6,230,000.
Then we count how many decimal places it takes before we have one leading digit. Since it is six, we move the decimal place and write 6.23*10^6
Since DB is the median of the triangle, it would bisect the base AC. This would mean that AB and BC are equal halves of the whole AC. So, if AC is 50, then,
AC = AB + BC
since AB = BC,
AC = 2AB
50 = 2AB
AB = 50/2
AB = 25
The answer is 25.
