For a chemistry lab, you used 2 ounces of calcium sulfate, 2.5 pounds of copper, and 1 4 lb of nickel. what was the combined weight of your materials?

Total weight = 266 ounce

Step-by-step explanation:

In this question we have to tell the combined weight of the materials in the same unit.

Weight of calcium sulfate = 2 ounces

Weight of copper = 2.5 pounds

Therefore weight of copper in ounces will be = 2.5× 16 ounces = 40 ounces

Weight of nickel = 14 pounds = 14 × 16 ounces = 224 ounces

So total weight = 2 + 40 + 224 = 266 ounces

Answer is 266 ounces is the combined weight of the materials.

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
