Answer:

Bronze

Step-by-step explanation:

Let's calculate the density of this necklace.

Density is mass divided by volume: m / v. Here, we know the mass is m = 192 grams, and we also know the volume is v = 19.5 cubic centimetres. Plug these into the equation:

d = m / v

d = 192 / 19.5 = 9.85 g / cm³

Looking at the chart, the closest density to this is that of bronze, which is 9.87. So, the necklace is likely made of bronze.

Answer:

D) 1,036,800 boxes

Step-by-step explanation:

The volume of a box is ...

(20 in)(18 in)(15 in) = 5400 in^3

The volume of the storage space is ...

(300 ft)(240 ft)(45 ft) = 3,240,000 ft^3

Then the number of boxes that will fit in the storage space is ...

(3240000 ft^3)(1728 in^3/ft^3)/(5400 in^3/box) = 1,036,800 boxes

3. What is the distributive property of 40 + 64?

Ivan

Answer:

104

Step-by-step explanation:

This is not a distributive property question though.

A distributive property has a number (a) outside the parenthesis

a(b+c)

so in this case a(40+64)

then you would multiply a by both numbers

40a+64a

then add them together

104a

However if it is a number outside the parenthesis and not a variable, it will come out different

For example

5(40+64)

(5*40)+(5*64)

200+320

520

Hope this helps!

Which set of ordered pairs could be generated by an exponential function?

olasank [31]

Answer:

The correct option is (1,2), (0, 1), (1, 2), (2, 4).

Step-by-step explanation:

Consider the provided ordered pairs.

The exponential function is in the form of $f(x)=ab^x$

Where, a is the initial amount $a\neq 0$ and b is the rate of change b>0, $b\neq 1$

The graph of each exponential function passes through the point (0, a),

$f(0)=a\cdot b^0 = a$ and $a\neq 0$

Therefore, Option 1 and 2 and 4 are false.

Hence, the correct option is (1,2), (0, 1), (1, 2), (2, 4).
