The answer is:  A. –3, \sqrt{81}, 5, \frac{56}{7}.

The explanation is shown below:

1) By definition, the integers include whole numbers, negative numbers and zero.

2) Therefore, keeping this information on mind, you have that:

-3 is a negative number without decimal part, therefore, it is an integer.

3.7 is decimal number, so it is not an integer.

\sqrt{81}=9 (It is a whole number, therefore, it is an integer).

-7.34 is a decimal number, so it is not an integer.

\sqrt{8}=2.828 is an irrational number. It is not an integer.

5 is a whole number, therefore, it is a integer.

\frac{56}{7}=8 (It is a whole number, then, it is an integer).

What is z equal to ? Please help
MakcuM [25]
The sum of the interior angles of a triangle (half the rhombus in this case) is 180. Because of the properties of a rhombus, z and x will be equal to each other. Therefore, 124 + z + z = 180.
124 + z + z = 180
124 + 2z = 180
2z = 56
z = 28
Thus, z is equal to 28.

Tema [17]

Answer:

x = 48°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°, thus

x = 180° - (90 + 42)° = 180° - 132° = 48°

In 2003 Exxon Mobil received a contract from the government worth $756,733 while Aerospace received a contract from the governme
lutik1710 [3]

The combined total of their contracts is $1,296,250

<h3>How to determine the combined total?</h3>

The values of the contracts are given as:

  • Exxon Mobil= $756,733
  • Aerospace = $539,517

The combined total is represented as:

Total = Exxon Mobil + Aerospace

Substitute known values

Total = $756,733 + $539,517

Evaluate the sum

Total = $1,296,250

Hence, the combined total of their contracts is $1,296,250
