Answer:
200 bags are needed
Step-by-step explanation:
First let us determine the area of the corn field:
Shape of cornfield = square
Area of a square = Length × Length
where: Length = 100 yards
∴ Area = 100 × 100 = 10,000 square yards
1 bag of fertilizer is needed to cover 50 square yards:
50 square yards = 1 bag of fertilizer
Hence, 200 bags are needed.
<h3>The measure of angles of triangle are 96 degree, 36 degree and 48 degrees</h3>
<em><u>Solution:</u></em>
The ratio of the measures of the angles in a triangle is 8:3:4
Let the first angle be 8x
Let the second angle be 3x
Let the third angle be 4x
We know that,
sum of all angles in triangle is 180 degrees
Therefore,
8x + 3x + 4x = 180
15x = 180
x = 12
Thus,
First angle = 8x = 8(12) = 96
second angle = 3x = 3(12) = 36
third angle = 4x = 4(12) = 48
Thus measure of angles of triangle are 96 degree, 36 degree and 48 degrees

Comments:
We can see that as long as we add/subtract any value to both sides nothing happens: true statements remain true and false statements remain false. But if we multiply or divide by negative values, false statements become true and true statements become false. That why, when you multiply or divide an inequality by a negative number, you should also flip the inequality sign. For example, if we start with the true inequality
If we multiply both sides by -2 we have to flip the sign as well:
And the inequality will remain true.
