Options:

The reasonable domain contains only positive real numbers.

The reasonable domain contains only positive whole numbers.

The reasonable domain contains only real numbers greater than 3.

The reasonable domain contains only rational numbers greater than 3.

Answer:

(b) The reasonable domain contains only positive whole numbers.

Step-by-step explanation:

Given

[tex]f(x) = 0.5x + 3[/tex]

Required

True statement about the limitation of the domain

Since the domain (x) represents people, then it must be a positive whole numbers

This eliminates options (a) and (c)

The range of the function is not given. So, we can assume that any number of people can be present.

This eliminates option (d).

Hence: (b) answers the question

Answer:

- 5° < 0 < 7°

Step-by-step explanation:

Given that:

Sunday at noon :

Temperature = 5° below Zero

Wednesday at noon

Temperature = 7° above Zero

Temperature on Sunday noon < 0 < temperature on Wednesday noon

The Volume of the rectangular prism is 210cm

Answer:

The missing number of chicken nuggets is 5.

Step-by-step explanation:

To find the mean of this data set, we must add every number together, then divide the sum by how many numbers are present.

Like this,

1 + 3 + 0 + 6 = 10

10 / 4 = 2.5

There are 4 present numbers in this data set, and one is missing.

Since the only number divided by 5 that would give you a quotient of 3 is 15, the missing number is 5.

Because,

1 + 3 + 0 + 6 + 5 = 15

15 / 5 = 3

Therefore, 5 is the missing number of the data set.

Answer:

b. 5z-10 = 5(z-2)    c. c-2c^2= c(1-2c)    d. r+r+r+r= r(1+1+1+1)= 4r   e. 2x-(1/2) = (1/2)(4x-1)

Explanation:

you just need to find a common factor that you can divide out  of each term. ex. with the 5z-10 both 5z and 10 are divisible by 5, so you can factor that out. to check the answers just multiply it. if you still don't get it, look up "factoring binomials"

Answer: D- a reflection of ^RST across the line y=-x

Step-by-step explanation:

The solution is, O a reflection of RST across the line y=-x, is the reflection which will produce an image of RST with a vertex at (2, -3).

Reflection is a type of transformation that flips a shape in a mirror line (also called a line of reflection) so that each point is the same distance from the mirror line as its reflected point.

here, we have,

from the given figure,

we get,

Triangle RST has,

vertex R ( -1,3)

vertex S ( 3, -2)

vertex t (1, -4)

now we know that,

the rule of a reflection across the line y=-x,

(x, y) ⇒ (-x, -y)

so, we get, here,

vertex S ( 3, -2) ⇒ vertex at (2, -3)

so, there is  O a reflection of RST across the line y=-x.

Step-by-step explanation:

Answer:

i believe the answer is 10.5

Step-by-step explanation:

dime = 3.14 (1.8) =5.62 cm

Since the coin rolled about 10.5 cm in 4 rotations, it means that the circumference of the coin (x) multiplied by 5 is equal to the distance rolled.

4x=41.8

x =41.8/4 =10.5cm

good luck :)

Answer:

Miguel needs 1,369/9 square inch of carpeting

Step-by-step explanation:

Here, we want to know the size of carpeting needed to cover the floor

What we have to do here is to find the area of the bedroom floor

Mathematically, we have this as the product of the dimensions of the floor;

This will give;

12 1/3 inches * 9 1/4 inches

= 37/3 * 37/3 = 1,369/9 square inches

Answer:

125

Step-by-step explanation:

In ΔPTO we are given that

∠PTO = 90° (indicated by the right angle)

and ∠TPO = 35°

And we need to find the exterior angle (∠TOB)

If you didn't know this is the rule about exterior angles

Exterior angles of a triangle are equal to the sum of the opposite interior angles of a triangle

So more specifically for this problem

∠TOB = ∠PTO + ∠TPO

Now that we have created an equation we want to plug in the values that we are given

∠TOB = 90 + 35

90 + 35 = 125

Therefore the answer is 125

Vertical angles meet at a point of intersection and are equal.

From the figure given, the angles are vertical angles. Hence;

7x + 3 = 10x - 24

Collect like terms

7x - 10x = -24- 3

-3x = -27

x = 9

Answer:

Area of the given right triangle = 24 square units.

Step-by-step explanation:

Given triangle in the picture is a right triangle.

Area of a right triangle is given by,

Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

Height of the given triangle = 8 unit

Base of the given triangle = 6 unit

Area of the triangle = [tex]\frac{1}{2}(6)(8)[/tex]

                                 = 24 square units

Therefore, area of the given right triangle is 24 square units.
