Answer: one cup of milk contains 300 mg of calcium
Step-by-step explanation:
25% of 1200 is 300
Explanation:
1. The set of points 5 cm from the nearest point on a circle of radius 2 cm will be a circle with a radius 5 cm larger: a circle with a radius of 7 cm.
__
2. The set of points 6 in from the nearest point on a line will be a cylindrical shell 12 inches in diameter centered on the line.
If AB is a line segment, then the shell will have hollow hemispherical ends of radius 6 inches about the end points.
Answer: 199,990
Step-by-step explanation:
You can't round to the nearest tenth because you don't have a decimal added to the number.
I rounded to the nearest tens and got 199,990
<h3>
Answer:</h3>
✔ Angle 3 and 8
✔ Angle 7 and 4
Explanation:
<u>Vertically Opposite Angles are the angles opposite each other when two lines cross. "Vertical" in this case means they share the same Vertex (corner point), not the usual meaning of up-down</u>.
In order for the inverse to exist, the matrix cannot be singular, so we need to first examine the conditions for existence of the inverse.
Compute the determinant. The easiest way might be a cofactor expansion along either the first row or third column; I'll do the first.

The matrix is then singular whenever

.
With this in mind, compute the inverse.
