Answer:
[tex]\{(2,8),(2,1),(-9,-5),(-8,9)\}[/tex] is not a function
Step-by-step explanation:
Given
[tex]\{(-3,-1),(8,-1),(0,-5),(-9,-2)\}[/tex]
[tex]\{(5,9),(-3,-5),(0,4),(-9,9)\}[/tex]
[tex]\{(9,0),(-5,4),(5,0),(6,3)\}[/tex]
[tex]\{(2,8),(2,1),(-9,-5),(-8,9)\}[/tex]
Required
Which is not a function
A function is of the form [tex](x,y)[/tex]
Assume a function is:
[tex]\{(x_1,y_1),(x_2,y_2),(x_3,y_3).....,(x_n,y_n)\}[/tex]
In simple terms:
For an ordered pair to be regarded as a function, no x value must be repeated
Analyzing the options:
1. [tex]\{(-3,-1),(8,-1),(0,-5),(-9,-2)\}[/tex]
This is a function because none of the x values (-3, 8, 0 and -9) appeared more than once
2. [tex]\{(5,9),(-3,-5),(0,4),(-9,9)\}[/tex]
This is a function because none of the x values (5, -3, 0 and -9) appeared more than once
3. [tex]\{(9,0),(-5,4),(5,0),(6,3)\}[/tex]
This is a function because none of the x values (9, -5, 5 and 6) appeared more than once
4. [tex]\{(2,8),(2,1),(-9,-5),(-8,9)\}[/tex]
This is not a function because one of the x values (2) appeared more than once.
i.e.
[tex](2,8)[/tex] and [tex](2,1)[/tex]
3. Plantea un sistema de ecuaciones y halla las dimensiones de un rectángulo cuya altura mide 2 cm más que su base y cuyo perímetro es igual a 24 cm. 4. Resuelve por el método de igualación el siguiente sistema de ecuaciones
Answer:
Height = 5
Width = 7
Step-by-step explanation:
Given that :
Height of rectangle = 2 + Width
Let width = x
Height = x + 2
Perimeter = 24 cm
Perimeter of a rectangle ;
P = 2( height + Width)
P = 24 ; Length = x + 2 ; x
24 = 2(x + 2 + x)
24 = 2(2x + 2)
24 = 4x + 4
24 - 4 = 4x
20 = 4x
x = 5
Height = 5
Width = x + 2 = 5 +2 = 7

Hannah completed 1/2 an hour she had to complete 4 math problems she spent and equal amount on each problem how much of and hour did Hannah spend on each problem
Answer: 1/8 hours or 7.5 minutes
Step-by-step explanation:
Since Hannah spent 1/2 an hour to complete 4 math problems. We are further told that she spent an equal amount of time on each problem.
The amount of time spent on each problem will be:
= 1/2 ÷ 4
= 1/2 × 1/4
= 1/8 hours
Since 60 minutes = 1 hour
1/8 hours = 1/8 × 60 = 7.5 minutes each.
During one waiter’s shift, he delivered appetizers, entrées, and desserts. What percentage of the dishes were desserts? appetizers? entrées? What do your percentages add up to?
15 desserts
10 entrees
15 appetizers
Answer:
percentage of the dishes were desserts = 37.5%
percentage of the dishes were entrees = 25%
percentage of the dishes were appetizers = 37.5%
Total percentage = 100%
Step-by-step explanation:
Desserts = 15
Entrees = 10
Appetizers = 15
Total dishes = desert + entrees + appetizers
= 15 + 10 + 15
= 40
What percentage of the dishes were desserts?
= 15 / 40 × 100
= 0.375 × 100
= 37.5%
What percentage of the dishes were entrees?
= 10 / 40 × 100
= 0.25 × 100
= 25%
What percentage of the dishes were appetizers?
= 15 / 40 × 100
= 0.375 × 100
= 37.5%
What do your percentages add up to?
Total percentage = 37.5% + 25% + 37.5%
= 100%

There are 33 times as many boys as girls in a room. If 4 boys and 4 girls leave the room, then there will be 5 times as many boys as girls in the room. In total, how many boys and girls were in the room originally
Answer:
here are 3 times as many boys as girls in a room. If 4 boys and four girls leave the room, then there will be 5 times as many boys as girls in the room. In total, how many boys and girls were in the room originally?
8 girls
24 boys
There were 24 boys and 8 girls in the room originally.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
Given that there are 3 times as many boys as girls in a room.
If 4 boys and 4 girls leave the room, then there will be 5 times as many boys as girls in the room.
Let's assume the number of boys would be b
And the number of girls would be g
According to the given condition, the required solution would be as:
b = 3g ....(i)
b - 4 = 5 (g - 4) ....(ii)
Substitute the value of b = 3g in equation (ii), and solve for g
3g - 4 = 5 (g - 4)
3g - 4 = 5g - 20
5g - 3g = 20 - 4
2g = 16
g = 8
Substitute the value of g = 8 in equation (i), and solve for b
b = 3 × 8
b = 24
Hence, there are 24 boys and 8 girls in the room.

Alandra's rectangular cake pan is 33cm by 23 cm. She has enough cake batter to fill it to a depth of 3 cm. Instead, Alandra wants to pour the batter into ice cream cones. She plans to fill each cone to a depth of 9 cm with a diameter of 4 cm. How many whole cones can Alandra fill?
Answer:
Alandra can fill 60 whole cones
Step-by-step explanation:
The volume of a rectangular prism is V = L × W × H, where
L is its lengthW is its widthH is its heightThe volume of the cone is V = [tex]\frac{1}{3}[/tex] π r² h, where
r is the radius of its baseh is its height∵ Alandra's rectangular cake pan is 33 cm by 23 cm
∴ L = 33 cm and W = 23 cm
∵ She has enough cake batter to fill it to a depth of 3 cm.
∴ H = 3 cm
→ Find the volume of the batter using the 1st rule above
∵ V = 33 × 23 × 3
∴ V = 2277 cm³
∵ Alandra wants to pour the batter into ice cream cones
∵ She plans to fill each cone to a depth of 9 cm with a diameter of 4 cm
∴ h = 9 cm
∵ r = [tex]\frac{1}{2}[/tex] diameter = [tex]\frac{1}{2}[/tex] (4)
∴ r = 2 cm
→ Substitute them in the 2nd rule above to find the volume of each cone
∵ V = [tex]\frac{1}{3}[/tex] (π) (2)² (9)
∴ V = 12π cm³
→ To find the number of cones divide the volume of the batter by
the volume of each cone
∵ Number of cones = 2277 ÷ 12π
∴ Number of cones = 60.3993
→ We will take the whole number only because we need the whole cones
∴ Alandra can fill 60 whole cones

A student on the cross- county team runs 30 minutes a day as a part of her training. Write an equation to describe the relationship between the distance she runs in miles, D, andher running speed,in miles per hour,when she runs at a constant speed of 5.4miles per hour for m minutes,and then at be miles per hour for n minutes
Answer:
The answer is below
Step-by-step explanation:
A student on the cross- county team runs 30 minutes a day as a part of her training. Write an equation to describe the relationship between the distance she runs in miles, D, and her running speed, in miles per hour, when she runs at a constant speed of 5.4miles per hour for m minutes, and then at b miles per hour for n minutes
Solution:
Given that the student runs for a total of 30 minutes per day. He runs at 5.4 miles per hour for m minutes, and then at b miles per hour for n minutes.
Hence:
m + n = 30
60 minute = 1 hour. Therefore, m minute = m/60 hour, n minute = n/60 hour.
The distance traveled is the product the speed in miles per hour and the time taken to cover the distance. Distance = speed * time
The total distance ran (D) is:
D = 5.4(m/60) + b(n/60)
