Answer:

− 11   Integers

2.45  Rational Number

1      Natural Number ( whole number)

− 11/7   Rational Number

Step-by-step explanation:

Natural numbers are numbers which are positive numbers i.e these do not include negative numbers and can be counted such as 1,2,3,4,5------ .Natural numbers do not include a zero.

Whole numbers are natural numbers but these include a zero e.g 0,1,2,3,4,5------

Integers are whole numbers but can be negative as well.

Rational Numbers are numbers in the form of p/q where q ≠0

Answer:

Number of rats : Food weight = 1 : 5

Step-by-step explanation:

Number of rats in the group = 9

Weight of food carried away by them = 45 kg

Ratio of the number of rats and food weight = [tex]\frac{\text{Number of rats}}{\text{Weight of food carried by the rats}}[/tex]

                                                                          = [tex]\frac{9}{45}[/tex]

                                                                          = [tex]\frac{1\times 9}{5\times 9}[/tex]

                                                                          = [tex]\frac{1}{5}[/tex]

Therefore, Number of rats : Food weight = 1 : 5

Answer: x < 4

Step-by-step explanation: Move the constant to the right (5). Simplify (3+5=8).  Divide both sides (8/2 & 2/2).

Answer:

Step-by-step explanation:

[tex] \csc(a) = \frac{1}{ \sin(a) } \\ \sin(a) = \frac{15}{25} \\ \\ \csc(a) = \frac{1}{ \frac{15}{25} } \\ \\ \csc(a) = \frac{25}{15} [/tex]

Answer:

D) (10,22)

Step-by-step explanation:

based on given slope and point, the linear equation is y = 9/5x + 2

plugging in x-and-y values only results in a true statement for option D

example:

22 = 9/5(10) + 2

Does 22 = 18 + 2?  Yes

Step-by-step explanation:

diameter = 68ft

Radius = 34ft (68/2)

Circumference =213.6283 (68 x pi)

Answer:

60 degrees

Step-by-step explanation:

This is an equilateral triangle. Each angle has the same measure. There are three angles. So: 180 ÷ 3 = 60.

Answer:

60

Step-by-step explanation:

The figure shown is a triangle

To be more specific an equilateral triangle.

We know that this is an equilateral triangle because all of the side lengths are congruent ( indicated by the little mark on each side ) and if each side length is congruent then each angle is congruent.

Because the sum of the angles in a triangle adds up to equal 180 we can simply find the measure of each angle by dividing 180 by 3

180/3=60

so every angle = 60 degrees

Therefore your answer is 60

Answer:

Area: 28.26ft², Circumference: 18.84ft

Step-by-step explanation:

Area of a circle: πr²

Circumference of a circle: πd (or 2πr)

Since the diameter is 6ft, then the radius is half of that, which is 3ft. This means that our area is:

πr²

π(3)²

π(9)

9π

9(3.14)

28.26ft²

Our circumference is:

πd

π(6)

6π

6(3.14)

18.84 ft

Answer:

x=35

Step-by-step explanation:

175 minutes of driving time would be involved for Jesse according to the survey.

Some basic rules of surveying are:

Given, Jese wants to start driving himself to and from school each day He surveyed neighbors who live on his block and drive to school data.

For better understanding, a picture is attached below.

Add up the 8 different times then divide by 4 to get the average driving time for 1 day:

⇒ 12 + 18 + 13 + 21 + 15 + 22 + 15 + 22 = 138

⇒ 138 ÷ 4 = 34.5 mins

Now multiply the average drive time for 1 day by 5 to determine the time taken to drive to and from school for 5 days:

⇒ 34.5 x 5 = 172.5 minutes

As 172.5 ≈ 175 minutes, the nest response is 175 minutes

Therefore, According to the study, Jesse would require 175 minutes of driving time.

Answer:

Area of rectangle cage = 336 feet²

Step-by-step explanation:

Given:

Wire required for fencing = 100 feet

Width of rectangular cage = 8 feet

Find:

Area of rectangle cage

Computation:

Wire required for fencing = perimeter of cage

Perimeter of rectangular cage = 100 feet

2[l + b] = 100 feet

l + 8 = 50 feet

Length of rectangular cage = 42 feet

Area of rectangle cage = Length x Width

Area of rectangle cage = 42 x 8

Area of rectangle cage = 336 feet²

An example of a compound event is an event of having rolled two dice getting 6 on each. A compound event can consist of independent elementary events. This is the case when the result of any one elementary event does not have any influence on the result of another. An example with two dice above is such a compounded event.
