Answer: C
Step-by-step explanation:
Given 2 similar solids whose
ratio of sides = a : b, then
ratio of areas = a^2 : b^2 and
ratio of volumes = a^3 : b^3
Here the area ratio = 169 : 81, thus
side ratio = sqrt{169} : sqrt{81} = 13 : 9
Hence the volume ratio = 13^3 : 9^3
Using proportion then
frac{13^3}{9^3} = frac{124.92}{x} → C

Answer:
BD and BE are tangents to the circle
Step-by-step explanation:
Given
See attachment
Required
What does BD and BE represent?
From the attachment, we have:



The measure of angles between a tangent and the radius of a circle is always 
So, because
and AD is a radius, then BD is a tangent to circle.
Similarly,;
and AE being a radius implies that BE is a tangent to circle.
You multiple the number by 0.075
Answer:
y = 2x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
- 2x + y = 1 ( add 2x to both sides )
y = 2x + 1 ← in slope- intercept form
