Answer:
D.
Step-by-step explanation:
This inequality does not have ≤ nor ≥. This indicates that when the inequality is graphed on a number line, it will be an open circle.
Using this information, we can eliminate options A, B, and C.
This inequality also indicates that 'd' is less than 4; 4 is greater than 'd.'
Since 'd' is less than 4, the line would go toward the numbers less than 4.

<h3>What is percentage?</h3>A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by whole and multiply by 100.
Given
An mp3 player is on sale for 30% off the regular price of $39. 98.
The price of the mp3 player after the 30% is given
The cost of mp3 player after 30% discount is;
= $39.98 - $11.99 = $27.98
Hence, the cost of the mp3 player after the discount is $27.98.

Answer:
The area of rhombus PQRS is 120 m.
Step-by-step explanation:
Consider the rhombus PQRS.
All the sides of a rhombus are equal.
Hence, PQ = QR = RS = SP = 13 m
The diagonals PR and QS bisect each other.
Let the point at of intersection of the two diagonals be denoted by <em>X</em>.
Consider the triangle QXR.
QR = 13 m
XR = 12 m
The triangle QXR is a right angled triangle.
Using the Pythagorean theorem compute the length of QX as follows:
QR² = XR² + QX²
QX² = QR² - XR²
= 13² - 12²
= 25
QX = √25
= 5 m
The measure of the two diagonals are:
PR = 2 × XR = 2 × 12 = 24 m
QS = 2 × QX = 2 × 5 = 10 m
The area of a rhombus is:
Compute the area of rhombus PQRS as follows:
Thus, the area of rhombus PQRS is 120 m.
