Answer:
B. 50 times greater
Step-by-step explanation:
Given;
size of phytoplankton = 2 × 10⁻⁶ in
size of sand grain = 1 × 10⁻⁴ in
Determine how many times longer the grain of sand is than the phytoplankton.
Divide the sand size by the phytoplankton size, to find out how much greater the sand is.
This can be done by equating it as follows;
2 × 10⁻⁶ (y) = 1 × 10⁻⁴

Therefore, the grain of sand is 50 times greater than the phytoplankton
B. 50 times greater
Answer:
a.Corresponding angles
b.Alternate exterior angles
c.Consecutive interior angles
Step-by-step explanation:
a.
are corresponding angles.
- Two angles on the same side of the transversal either below or above of the two lines are corresponding angles.
b.
are alternate exterior angles.
- Pair of angles in which one arm of each of the angles lies on opposite sides of the transversal.
c.
are consecutive interior angles.
Consecutive interior angles are also called co-interior angles.
- Angles which are lying on the same side of a transversal cutting across the the two lines which are parallel.
So the pair of
are corresponding angles the pair of
are alternate exterior angles,the pair of
are consecutive interior angles.
//I'll use the discriminant rule for this.
b^2 - 4ac = 0 when one real root
Therefore, k^2 - 4*3*4= 0
k^2 = 48
k= +-4√3
