Is 49 prime or composite

Answer:

mercury's volume is 14.6 billion cubic miles

Iron's density is 7.874 grams per cubic centimeter

Lead's Mass is 207.2 atomic mass units

Gold's volume is 1.61 cubic centimeters.

Aluminium's mass is 26.981539 u

Copper's volume is 1.5 mL

Marble's density 2711 kg

Teak's density is 41 lbs (might be wrong sorry if it is)

Concrete's Volume is Calculating the volume for concrete requires using three dimensions: length times width (which is area) times the height (thickness) or L x W x H. If you are using feet as your standard unit of measurement, this formula will give you the volume of concrete in cubic feet.

|80 - 5x| ≤ 4

• This is about absolute value inequality.

He is buying 5 tickets.

He wants his total cost to be in the range of 80 ± 4.

• If the cost of one ticket is $x, then we have;

5x - 80 ≤  4

5x ≤ 84

x ≤ 16.8

• Also; 80 - 5x ≤ 4

5x ≥ 76

x ≥ 15.2

• From absolute values, since;

5x - 80 ≤  4 and 80 - 5x ≤ 4

we can express this inequality as;

|80 - 5x| ≤ 4

Final answer:

To model the cost x, in dollars, of a concert ticket, the inequality 80 - 4 ≤ x ≤ 80 + 4 can be used.

Explanation:

To model the cost x, in dollars, of a concert ticket, we can write the following inequality:

80 - 4 ≤ x ≤ 80 + 4

This inequality states that the cost of a ticket, x, must be between $76 and $84 (inclusive),

in order for Jamie's total cost for 5 tickets to be no more than $4 above or below $80.
