Answer:
a) yes (a function)
b) no (not a function)
Step-by-step explanation:
A functional relationship will have only one value of dependent variable for each value of independent variable. That is, the column on the left can only have one arrow tail per item.
__
a) is a function. Each independent variable maps to one dependent value
b) not a function. Independent variable values 7 and 30 map to two values each.

Janet has a $65 budget to buy paper goods and plastic cutlery for an impromptu birthday party. She determines that the paper goods will cost $37.50. How many sets
of cutlery can she purchase if each set costs $0.75?
Janet can purchase 36.67 sets of cutlery if each set costs $0.75.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
Janet has $65 to spend on paper goods and cutlery, and the paper goods will cost $37.50,
So, she has $65 - $37.50 = $27.50 remaining to spend on cutlery.
Each set of cutlery costs $0.75,
So, Janet can purchase sets of cutlery :
⇒ $27.50 / $0.75
Apply the division operation, and we get
⇒ 36.67
Since it's not possible to buy a fraction of a set, Janet can only buy 36 sets of cutlery.
Therefore, she can purchase 36.67 sets of cutlery.

(12x)"
O

66°
62°
Answer:
X equals 8.
Step-by-step explanation:
The polygon in the question has 5 sides. However, it is an irregular polygon hence the sides are given as 62 degrees, 66 degrees, 77 degrees, 59 degrees and 12X degrees.
The size of the exterior angle of a polygon is calculated as
Angle = 360/n
Where n is the number of sides. So for a five sided polygon, the size of the exterior angle is calculated as
360/5 which equals 72. Since it is an irregular polygon, the sum of the exterior angles can be expressed as
62 + 66 + 77 + 59 + 12X = 360
264 + 12X = 360
Subtract 264 from both sides of the equation
12X = 96
Divide both sides of the equation by 12
X = 8
The value of x in the given polygon is 8.
What is Polygon?A polygon is a plane figure made up of line segments connected to form a closed polygonal chain
The polygon in has 5 sides.
It is an irregular polygon hence the sides are given as 62 degrees, 66 degrees, 77 degrees, 59 degrees and 12X degrees.
The size of the exterior angle of a polygon is calculated as
Angle = 360/n
Where n is the number of sides.
So for a five sided polygon, the size of the exterior angle is calculated as
360/5 =72.
Since it is an irregular polygon, the sum of the exterior angles can be expressed as
62 + 66 + 77 + 59 + 12X = 360
264 + 12X = 360
12X = 96
Divide both sides of the equation by 12
X = 8
Hence, the value of x in the given polygon is 8.

( show your work ) The banner that football players run through is 18 feet high and 30 feet long. How much paper is needed to
construct a banner ?
Answer:
540 square feet worth of paper
Step-by-step explanation:
This is an area problem. Area is length multiplied by width. The provided length is 30 feet and the provided width is 18 feet. When they are multiplied, you get 540 square feet. Note that the height is the width in this context because if you laid the banner down, 18 would be the width. The banner is being held up, so the 18 feet is called the height.

44 is the product 4 and Greg's height. Use the variable g to represent Greg's height
Step-by-step explanation:
do you happen to have a photo reference your sentence is a bit confusing
Answer:
44 = 4 · g OR g · 4 = 44
Step-by-step explanation:
So first we need to know what a variable is...
A variable is an unknown number in a math sentence
Knowing that we can write the equation.
"44 is the product 4 and Greg's height. Use the variable g to represent Greg's height"
Since we do not know Greg's height that is what we will use variable g to substitute it.
"44 is the product 4 and g"
Now all we have to do is convert this into an equation
(Note: Whenever you see product of something know that it means that you need to multiply)
So your final answer is...
44 = 4 · g
(Explanation: Since it says 44 is the product of then it means it is the answer so we will put an equal sign)

two complementary angels are in the ratio 4:5, find the angles.
Answer:
1 st angle = 40
2 nd angle= 50
Step-by-step explanation:
let 1 st angle be 4x and 2 nd angle be 5x4x +5x =90 9x =90 x=90/9 x= 10Answer:
First angle = 40
Second angle = 50
Step-by-step explanation:
let 1st angle be 4x and 2nd angle be 5x
4x + 5x = 90 [Complementary means the sum of angles is 90]
=> 9x = 90
=> x = 90/9
=> x = 10
First angle = 4x = 4(10) = 40
Second angle = 5x = 5(10) = 50
