Answer:
proportion: 1.93/23 = y/x
solve for y: y = x(0.083913)
Step-by-step explanation:
The required relationship of the proportionality is y = 0.08 x.
Given that,
In 23 minutes, Halona travels 1.93 kilometers to a neighbor's home. assuming she moves at a steady pace.
How many kilometers, y, Halona can walk in x minutes, expressed as a proportion. After that, find y using your percentage.
The relationship between two or more sets of values—whether they are directly proportional or inversely proportional to one another—is referred to as proportionality.
Here,
according to the question,
y ∝ x
y = kx
Where k is the constant of the proportionality,
at x = 23, y = 1.93
1.93 = 23 k
k = 1.93/23
k = 0.08
Put k in the proportionality equation,
y = 0.08k
Thus, the required relationship of the proportionality is y = 0.08 x.

CAN SOMEONE HELP ME PLS AAAAA? Jason purchased a cell phone on sale for $100. He will pay a $25 monthly service for the line. Write an equation for this scenario. Is this a proportional relationship?
Answer:
Step-by-step explanation:
y = 25x +100
y- is the total money spent on the phone
x-is the number of months you had service
the relationship between x and y is proportional ( if x grows, y grows)
For example: after 2 months you would had payed $100 for the phone + the $25 each of the 2 months. y= 25*2 +100 = $150

Point A is located at –24 and point C is located at 36 on the number line below.
Which value would represent point B, halfway between point A and point C?
Answer:
Please check the explanation.
Step-by-step explanation:
A number line is a horizontal line with negative values on the left-hand side of an arbitrary number 0 and positive values on the right-hand side of 0.
The location of point A on a number line = -24
The location of point C on a number line = 36
The distance between -24 and 36 can be simply calculated by counting the number of units between.
Starting from -24, we would need to move 24 units on the right side to reach the 0 and 36 units right to reach 36.
So, the total units will be: 24+36 = 60
A second simple method to calculate the distance between point A and point C is:
Distance between A and C = location of C - location of A
= 36 - (-24)
= 36+24
= 60 units
Thus, the distance between A and C is 60 units.
Now, point B is located halfway between point A and point C.
Thus,
The point B must be 30 units before (30 units on the left side) of the point C. In other words, point B must be 30 units after (30 units on the right side) of point A.i.e.
The location of point B = The location of point C - 30
= 36 - 30
= 6
Thus, point B is located at 6.
Verification:
The location of point B = The location of point A + 30
= -24 + 30
= 6
Thus, point B is located at 6.
Thus, it is verified that point B, halfway between point A and point C.
Hence,
'6' is the value of point B halfway between point A and point C.

Answer:
a) 3, 8, 63, 3968
b) some other kind
c) continue to evaluate terms sequentially
Step-by-step explanation:
a) To find the first four terms, use the recurrence relation:
t(1) = 3 . . . given
t(2) = t(1)^2 - 1 = 3^2 -1 = 9 -1 = 8
t(3) = 8^2 -1 = 64 -1 = 63
t(4) = 63^2 -1 = 3969 -1 = 3968
The first 4 terms are 3, 8, 63, 3968.
__
b) The terms have no common difference or ratio, so the sequence is some other kind of sequence. The ratios of terms form a sequence that is approximately exponential.
__
c) Colin can find the 10th term by evaluating successive terms using the recursion relation. (It is approximately 2.0351×10^230.)

D
30 cm
The length of the rectangle is increased by 10%.
The width of the rectangle is increased by 5%.
Find the percentage increase in the perimeter of the rectangle.
answer
15.5%
Step-by-step explanation:
length = 30
30+10%=33
breadth=20
20+5%=21
area of rectangle = length × breadth
600² centimeters = 30 × 20
693² centimeters = 33 × 21
Increase = 15.5%
3 1/2 divided by 2 3/4 (fractions)

Mrs.Salcido cut a small birthday cake into 6 equal pieces for 6 children. One child was not hungry. So she gave the birthday boy the extra piece. How much cake did each of the five children recieved.
Answer: The birthday boy got [tex]\dfrac13[/tex] of cake and rest each of the 4 children got [tex]\dfrac16[/tex] of cake.
Step-by-step explanation:
1 cake is divided into 6 pieces.
1 piece = [tex]\dfrac16[/tex]
Birthday boy got 2 pieces.
Part of cake he has = [tex]2\times\dfrac16=\dfrac26=\dfrac13[/tex] [divide numerator and denominator by 2]
So, birthday boy got [tex]\dfrac13[/tex] of cake and rest each of the 4 children got [tex]\dfrac16[/tex] of cake.

the vertex of y=(x-4)(x+2)
Answer:
(1,-9)
Step-by-step explanation:
Answer:
vertex = (1, - 9 )
Step-by-step explanation:
The vertex is located on the axis of symmetry
The axis of symmetry is at the midpoint of the zeros
Find the zeros by letting y = 0, that is
(x - 4)(x + 2) = 0
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 4 = 0 ⇒ x = 4
Then equation of axis of symmetry/ x- coordinate of vertex is
x = [tex]\frac{-2+4}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1
Substitute x = 1 into the equation for corresponding value of y
y = (1 - 4)(1 + 2) = (- 3)(3) = - 9
vertex = (1. - 9 )

Answer: The answers are:
6 + 2 = 8
4 + (-1) = 3
Step-by-step explanation:
Add 6 by 2.
Solve for X.
4 + X = 3
To find X, we use the integer rule. We can use this:
Positive and Positive = Positive
Negative and Negative = Negative
Positive and Negative = Both (It depends if the negative or positive is larger than the other)
For this problem, we can use: Positive and Negative = Both.
If we look at the chart, we can see 4 and 3. How can we get 4 + ? = 3? We can use the integer, -1. Since we said, Positive and Negative = Both, we must compare the positive-addend (4) by the negative-addend (-1).
4 is greater than -1
4 > -1
Therefore, X equals -1.
4 + (-1) = 3
Answer: 8, -1
Step-by-step explanation:
The table shows some addition problems. Each column is its own problem, with the first two rows being addends and the bottom row being the sum. Thus, simply do 6+2 to get the first blank(left-to-right), 8. Then, do 4+x=3 to get the second blank, or -1.

Jo owns a gas station in Ponder, Texas. Last year, Jo sold 5,000 gallons of
gasoline at a price of $1 a gallon. Jo's average cost of producing the
5,000-gallons of gasoline was 50 cents a gallon. Did Jo earn a profit? If so,
how much?
Answer:
Jo earned a profit of $2500.
Step-by-step explanation:
Given that:
Selling price of 5000 gallons = $1 per gallon
Total selling price = 1 * 5000 = $5000
Production cost = 50 cents per gallon = $0.5 per gallon
Total production cost = 0.5 * 5000 = $2500
Production cost < Selling cost
Therefore,
Jo earned profit on gasoline.
Profit = Selling cost - Production cost
Profit = 5000 - 2500
Profit = $2500
Hence,
Jo earned a profit of $2500.
