Answer 2
Answer:

Final answer:

The density of a substance, including gold, is calculated by dividing its mass by its volume. For the nugget of gold with a mass of 463.2 grams and a volume of 24.0 milliliters, the density is calculated as 19.3 g/mL.

Explanation:

The density of a substance can be calculated by dividing its mass by its volume. This is also known as the unit rate comparing mass to volume. In the case of the gold nugget, you have a mass of 463.2 grams and a volume of 24.0 milliliters. To find the density, you would divide the mass (463.2 g) by the volume (24.0 mL).

So, the calculation will be as follows:

Density = Mass / Volume = 463.2 g / 24.0 mL = 19.3 g/mL

Thereby the density of gold in this scenario is 19.3 g/mL.

What is the total cost of a $150.00 necklace if the sales tax is 6.5?

Answers

The best thing to do is to find what 1% is, and you can do this by dividing 150 by 100.
150/100= 1.5
As you're looking for 6.5%, you've got to multiply 1.5 by 6.5
1.5*6.5= 9.75
You've then got to add 9.75 and 150 together
150+9.75= $159.75
Therefore, after the sales tax, the cost of the necklace is $159.75

Alex bought 2 printer cartridges for $28 each and a printer for $85. He gave the cashier $150. How much change should Alex have received from the cashier?

Answers

Answer:

$9 in change

Step-by-step explanation:

Find the total cost of his purchases:

28 + 28 + 85

= 141

Find how much change he received by subtracting this from 150:

150 - 141

= 9

So, he should have received $9 in change

A triangle with base on an extended line. Two angle measures are given. Top interior angle is twenty-eight degrees. Lower left exterior angle is seventy-one degrees. Lower right interior angle is labeled x degrees.

Answers

The correct answer for the question that is being presented above is this one: "The lower right interior angle is 43°"

Interior angle of a triangle and its corresponding exterior angle must have a sum of 180° when its line is extended.

Top interior angle is 28°
Lower left exterior angle is 71°
Lower right interior angle is x°

Get the left interior angle. 
Exterior angle + Interior angle = 180°
71° + Interior angle = 180°
Interior Angle = 180° - 71°
Interior Angle = 109°

Top Interior angle + Left Interior Angle + Right Interior angle = 180°
28° + 109° + x° = 180°
x = 180° - 28° - 109°
x = 180° - 137°
x = 43°

The lower right interior angle is 43°
