The scale on a map is 1 : 30000
What is the actual distance represented by 1 centimetre?
When the scale on a map is 1 : 30000, the actual distance represented by 1 centimetre is 300 meters.
How to calculate the distance?It should be noted that in order to get the distance, we have to convert 1cm to meter. It should be noted that;
100cm = 1 meter
1cm = 1/100 = 0.01 meters.
Therefore, when the scale on a map is 1 : 30000, the actual distance represented by 1 centimetre will be:
= (0.01 × 300000)
= 300 meters.
Therefore, the distance is 300m

in the game of hearts, four players are each dealt 13 cards from a deck of 52. is this a function? if so, what are the domain and codomain? is the function injective, surjective, both (bijective), or neither?
Based on the fact the game of hearts, four players are each dealt 13 cards from a deck of 52
The domain is the deck of 52 cardscodomain is 4 playersfunction, f(k) maps a card to each playerIt is surjectiveThis is further explained below.
What is a surjective Function?A surjective function is a kind of function that exists in mathematics that ensures that any element y may be transferred to element x in such a way that f(x) equals y.
To put it another way, each element that makes up the function's codomain is the mirror image of at least one element that makes up the domain.
Generally, function, f(k) maps a card to each player
And since each player is dealt 13 cards st 13 of the cards are mapped to each player.
It is a function as one card is mapped to one and only one player.
The function is not injective because 13 cards 1 are mapped to one player so it is a many-one function but the injective function does not map two elements to a common clement.
In conclusion, It is surjective as each player is dealt 13 cards. the function is not injective hence rot bijective.

Using the alternate exterior angles theorem, the value of x is: 127°.
What is the Alternate Exterior Angles Theorem?When two parallel lines are intersected by a transversal to form alternate exterior angles that lie outside on each of the parallel lines, the alternate exterior angles theorem states that both angles are equal or congruent to each other.
From the diagram given, we are told that line m is parallel to line n. transversal t crosses both lines and n. The angles, x and 127 degrees are alternate exterior angles that lie on each parallel lines.
Therefore, the alternate exterior angles theorem states that, both angles would be equal.

The better deal of the given pair is $31.05/1. The unit rate is $2.07.
What is the better deal?The better deal is the deal that has the lower unit rate. Unit rate is the price per gallon. The unit rate can be determined by dividing the total cost by the total gallons bought.
Division is the operation that is used in mathematics to determine the quotient of two or more numbers. Division entails grouping a number into groups using another number. Other operations used in mathematics are addition, multiplication and subtraction.
Unit rate = total cost / number of gallons

The width of her room can be calculated as follows:
Therefore,
length = 12 ft 4 inches
Hence.

12 ft = 144 inches
Hence,
length = 144 + 4 = 148 inches
Therefore,
x = length + width
4 / 7 × x = 148
4x / 7 = 148

the volume of a cube shaped crate i 27 cubic feet. what is the length of one edge of the crate?
Answer: The length of the edge of the crate is 3 feet.
Step-by-step explanation:
The formula of the volume of a cube is the cube of edge length.
The volume of the cube (V) = (edge)³ ...................................(1)
In the given question volume is 27 cubic feet.
So, V = 27 cubic feet
Now we replace the Volume with the edge using equation (1)
i.e. (edge)³ = 27
or we can say that the cube root of the edge is equal to 27
i.e. edge = ∛27
which is equal to 3
hence, edge = 3 feet
To calculate the cube root write prime factors of 27 and group them in groups of three
i.e. ∛27 = ∛(3×3×3) = ∛ (3)³ = 3

2|x + 3|+1>3
Number line with open circles on -4 and -2, with shading in opposite directions.
Solution:Given: 2 |x + 3| +1 > 3 absolute value inequality.
We must solve and graph the following absolute value inequality:
2 |x + 3| +1 > 3
Take a look at the following absolute value inequality: 2 |x + 3| +1 > 3
We have to apply absolute rule:
If |u| > a , a > 0 then u < -a or u > a.
2|x + 3|+1 < -3 or 2|x + 3|+1 >3
Consider inequality first.
2|x + 3|+1 < -3
When we subtract 1 from both sides, we get,
2|x + 3| +1 -1 < -3 -1
Simplify,
2 |x + 3| < -4
We get by dividing both sides by two,
(2|x + 3|)/2 < -4/2
|x + 3| < -2
There is no solution for x ∈ R.
Now consider the second inequity.
2|x + 3|+1 >3
When we subtract 1 from both sides, we get,
2|x + 3|+1 - 1 >3 - 1
Simplify,
2|x + 3| >2
We get by dividing both sides by two,
(2|x + 3|) / 2 >3/2
|x + 3| > 1
x + 3 < -1 or x + 3 >1
x < -4 or x > -2
As a result, we have the solution to the absolute value inequality:
2|x +3|+1 > 3 as
