Answer:

The model does not represent a compound because it shows two atoms of the same element combined.

Compounds are made of two or more atoms of different elements.

Answer:

Step-by-step explanation:

The model shows two similar elements.

Although we do not know what the element is, we can conclude that the model is not a compound.

This is because the definition of a compound is when two different elements join.

However, the model has two similar elements, which forms a molecule, not a compound.

Point B is the center of a circle, and AC is a diameter of the circle. Point D is a point on the circle different from A and C.

seropon [69]

BA and BD are radii of the circle, so triangle ABD is isosceles. Then angles BDA and BAD are congruent, and the remaining (central) angle ABD has measure

$m\angle ABD=(180-2\cdot20)^\circ=140^\circ$

Angles ABD and CBD are supplementary, so

$m\angle CBD=(180-140)^\circ=40^\circ$

and the answer is E.

Answer:

5x+4y=49.50, where:

x is the price per sub

y is the price per drink

Step-by-step explanation:

From the information provided, you can say that the result of adding up the price per sub for the quantity plus the price per drink for the quantity is equal to 49.50 that is the total amount spent, which can be expressed as:

5x+4y=49.50, where:

A carpenter bought 750 nails. Each nail has a mass of 5.2×10−3 kilogram. What is the total mass, in kilograms, of the nails the

lawyer [7]

The total mass, in kilograms, of the nails the carpenter bought is 3.9 kilogram

<h3><u>Solution:</u></h3>

Given that carpenter bought 750 nails

Each nail has a mass of $5.2 \times 10^{-3}$ kilogram

To find: total mass, in kilograms of the nails bought

The total mass of the nails bought can be found out by multiplying number of nails bought by mass of each nail

Number of nails bought = 750

Mass of each nail = $5.2 \times 10^{-3}$ kilogram

total mass of the nails bought = number of nails bought x mass of each nail

$\text {total mass of the nails bought }=750 \times 5.2 \times 10^{-3}$

$\text {total mass of the nails bought }=3900 \times 10^{-3}=\frac{3900}{1000}=3.9$

Thus the total mass of nails bought is 3.9 kilogram
