What is the range of the function represented by these ordered pairs?
Answer:
B
Step-by-step explanation:
The range of a data set is the y-coordinates of the ordered pairs.
So, we have the ordered pairs:
{(-2,1), (0,0), (3,-1), (-1,7), (5,7)}
So, the range will be (the bolded numbers):
{(-2,1), (0,0), (3,-1), (-1,7), (5,7)}
Thus, our answer is:
{-1, 0, 1, 7}
Note that the range should be in ascending order.
Also note that even though 7 appears twice, 7 is 7, so we only put one 7.
The answer is B.

What is the shortest time needed for all four of them to cross the river ?
Answer:
13 minutes
Step-by-step explanation:
Person 1: 1 min
Person 2: 2 min
Person 3: 7 min
Person 4: 10 min
Person 1, 3, and 4 cross first, which will take 10 minutes.
Then, Person 1 comes back, taking 1 minute.
Person 1 and Person 2 cross the river, taking 2 minutes.
10 + 1 + 2 = 13 minutes.
Ask Richard swim underwater his elevation changes and family for six minutes altogether a change in -30 feet what was the change in elevation drink each minute what was the change in elevation during each minute
Answer:
The change of elevation during each minute is -5 feet per minute
Step-by-step explanation:
Here in this question, we are interested in calculating the change in elevation during each minute given that there was a total change of -30 feet in six minutes altogether.
Now, to calculate the change in elevation during each minute, we need to assume that the change in elevation per each of the minutes is the same.
So to calculate the change in elevation during each of the six minutes, we simply divide the total change in elevation by the total number of minutes.
Mathematically, that would be -30 feet/6 minutes = -5 feet per minute

Consider the tile pattern below. Completely describe what figure 100will look like. How many tiles will be in figure 100? Explain how you know
Answer:
101 up on the left
100 up on right
6 across the bottom
Step-by-step explanation:
their is always six along the bottom
up on the right is whateve number the figure is it increase one everytime
101 up on the left because figure one stats with 2 and from their one is added
The solution is
a) The figure will have 100 rows of 6 tiles and 1 row having 1 tile
b) The number of tiles in figure 100 will be 601 tiles
What is Arithmetic Progression?
An arithmetic progression is a sequence of numbers in which each term is derived from the preceding term by adding or subtracting a fixed number called the common difference "d"
The general form of an Arithmetic Progression is a, a + d, a + 2d, a + 3d and so on. Thus nth term of an AP series is Tn = a + (n - 1) d, where Tₙ = nth term and a = first term. Here d = common difference = Tₙ - Tₙ₋₁
Sum of first n terms of an AP: Sₙ = ( n/2 ) [ 2a + ( n- 1 ) d ]
Given data ,
Let the figure 100 be represented as = a₁₀₀
Let the number of tiles in the first figure be a₁
The value of a₁ = 7 tiles
Let the number of tiles in the second figure be a₂
The value of a₂ = 13 tiles
So , the common difference of the arithmetic sequence is d
d = second term - first term
d = 13 - 7
d = 6
Now , the value of figure a₁₀₀ is calculated by the formula
Tn = a + (n - 1) d
Substituting the values in the equation , we get
a₁₀₀ = 7 + ( 100 - 1 ) 6
a₁₀₀ = 7 + ( 99 x 6 )
a₁₀₀ = 7 + 594
The value of a₁₀₀ = 601
Therefore , the figure will have 100 rows of 6 tiles and 1 row having 1 tile
And , the total number of tiles in the figure is 601 tiles
Hence , The figure will have 100 rows of 6 tiles and 1 row having 1 tile and
the number of tiles in figure 100 will be 601 tiles

can you draw a triangle with 90 degrees 60 degrees and 60 degrees
Answer:
no
Step-by-step explanation:
the sum of interior angles of a triangle should be 180
so the three possible angles would be 90 degree 60 degree and 30 degree
Answer:
[tex]\huge\boxed{\sf NO.}[/tex]
Step-by-step explanation:
The interior angles of a triangle must be adding to 180 degrees for it to "be" a triangle.
Let's check if 90°,60° and 60° are adding to 180°.
=> 90+60+60
=> 210° > 180°
Since they are not adding to 180°, a triangle with the given angles cannot be formed.

When you're solving an equation, there are three possibilities. Two of which are chosen if your statement is true or not.
If you're able to get x alone, there is one solution. However, If all of the variables are eliminated and you're left with a false statement, that will be no solution. Example: 1=5? False.
If all of the variables are eliminated and you're left with a true statement, that solution is all real numbers. Example: 5=5? True.
A rectangular flour canister has dimensions of 512 inches by 4 inches by 10 inches. A smaller sugar canister has dimensions of 312 inches by 3 inches by 8 inches. How much smaller is the volume of the sugar canister than the flour canister?
Answer:
The amount by which the sugar canister is smaller than the flour canister is 136 in³
Step-by-step explanation:
The dimensions of the flour canister = 5 and 1/2 inches by 4 inches by 10 inches
(5 and 1/2 = (5 1/2))
(3 and 1/2 = (3 1/2))
The dimensions of the smaller sugar canister = 3 and 1/2 inches by 3 inches by 8 inches
The volume of the rectangular prism = Length × Width × Height
∴ The volume of the flour canister = (5 1/2) × 4× 10 = 220 in.³
The volume of the sugar canister = (3 1/2) × 3 × 8= 84 in.³
The difference in volume between the flour canister and the sugar canister is given as follows;
220 in.³ - 84 in.³ = 136 in.³
The amount by which the sugar canister is smaller than the flour canister = 136 in.³.

Choose the number line that correctly compares 24 and 4.256
A number line shows the comparison between numbers, at a regular interval.
The correct number line that compares [tex]\sqrt{24[/tex] and [tex]4.256[/tex] is (c)
The numbers are given as:
[tex]n_1 = \sqrt{24}[/tex]
[tex]n_2 = 4.256[/tex]
So, we have:
[tex]n_1 = \sqrt{24}[/tex]
Take square roots
[tex]n_1 = 4.899[/tex]
4.899 is greater than 4.256 i.e. [tex]n_1 > n_2[/tex]
So, we have:
[tex]\sqrt{24} > 4.256[/tex]
Number lines increases in value towards the right. This means that:
[tex]\sqrt{24}[/tex] will be at the right-hand side of 4.256[tex]\sqrt{24[/tex] will be between 4.8 and 4.9Hence, the correct number line is: (c)

of the fan.
min of
Answer:
MP = Rs. 1500
SP = Rs. 1230
Step-by-step explanation:
Let the Cost Price (CP) be x
Then Market Price (MP):
MP = x+ 20% = 1.2xDiscounted Selling Price (SP):
SP = MP - 18% = 0.82*1.2x = 0.984xSince the difference between CP and SP is Rs.20:
x - 0.984x = 200.016x = 20x= 20/0.016x = 1250Then:
MP = 1.2*1250= Rs. 1500and
SP = 1500*0.82 = Rs. 123013 people fit comfortably in a 5 foot by 5 foot area. Use this value to estimate the size of a crowd that is 5 feet deep on one side of the street along a 4 mile section of a parade route.
Answer:
There are 203069 people in the crowd
Step-by-step explanation:
The first step in solving this problem is to ensure that we are working with the same units throughout the solution process. To do this, we will have to convert 4 miles to feet. (This is because every other unit is in feet).
Note: ( 1 mile =5280 feet)
4 miles = 21120 feet.
The next step is to calculate the area that the entire parade is occupying. This can be done by multiplying the length of the parade by the breadth. In this case, it will be 21120ft X 5 ft = 105600 square feet.
We can now at this point, find the area occupied by only one person.
if 13 people occupy 25 square feet (5ft X5 ft)
1 person will occupy 25/13 = 1.92 square feet
We can finally get the number of people in the crowd by multiplying the area occupied by the whole crowd by the area of one person. This will be
105600 X 1.92= 203069 people in the crowd
