After solving the arithmetic sequences, he lengths of the first four segments will be 20 cm.
What is arithmetic sequences?Arithmetic sequences take the following format: a, a+d, a+2d, a+3d, etc. up to n terms. A is the first term; d is a frequent difference; and n is the total number of terms.
Find the AP, the number of terms, and the common difference for the calculation using the arithmetic sequence formulas. To determine the nth term, sum, or common difference of a given arithmetic sequence, various arithmetic series formulas are used.
To find the lengths of the first four segments we use the Arithmetic progression formula that is
[tex]a_n =[/tex] a₁ + (n - 1)d
Where
an = the nᵗʰ term in the sequence
a₁ = the first term in the sequence
d = the common difference between terms
We have a₁ as 5 cm and as it is being duplicated the common ration d is 5
and we have been asked the length of the first four segments, so n = 4
Lets substitute the given information
[tex]a_n =[/tex] 5 + (4 - 1)5
= 5 +(3)5
= 5 + 15
= 20
Thus, after continually duplicated segment ab, the lengths of the first four segments will be 20Cm

6) Ray is in debt $32 right now. He used to owe more, but he has been paying $6 a month on his debt for the last five months.
a) How much was Ray in debt 5 months ago?
b) At his present rate, how much longer will it take Ray to pay off his debt? Explain your reasoning.
Answer:
a)62
b)6 months
Step-by-step explanation:
a) if he pays $6 every month then you would times $6 by 5 to find out how much he paid off which is 30 so you would add that to the current amount therefore $30+$32=$62
b) You would do $32 divided by 6 to find out how much hit would take to pay off which is 5 but there is 2 remaining so he can pay that off the next month, so it takes 6 months

The slope of the given line a is found as 4.
What is described as the slope?A line's slope is the ratio of how much y increases even though x increases by some amount. The slope of a line indicates how steep it is, or how far y increases because x increases. The slope is stable (the same) throughout the line.If y is the vertical path on a graph and x is the horizontal direction, therefore this formula is: Slope = (Change in y)/(Change in x)For the given question;
The graph of the given line a is given.
Select any two points from the graph lying on the line.
(x, y) = (1, 1)
(x, y) = (2,5)
Thus, the slope will be;
Slope = m = (y - y)/(x - x)
m = (5 - 1)/(2 - 1)
m = 4/1
m = 4
Thus, the slope of the given line a is found as 4.

how do you solve 94 divided by 33 because when I tried solving it, it didn't make sense.
it's 2.84
step by step:
Start by setting it up with the divisor 33 on the left side and the dividend 94 on the right side.
The divisor 33 goes into the first digit of the dividend 9, 0 time(s). Therefore, put 0 on top.
Multiply the divisor by the result in the previous step (33 x 0 = 0) and write that answer below the dividend.
Subtract the result in the previous step from the first digit of the dividend (9 - 0 = 9) and write the answer below.
Move down the 2nd digit of the dividend 4
The divisor 33 goes into the bottom number 94, 2 time(s). Therefore, put 2 on top.
Multiply the divisor by the result in the previous step (33 x 2 = 66) and write that answer at the bottom.
Subtract the result in the previous step from the number written above it. (94 - 66 = 28) and write the answer at the bottom.
it's a repeating decimal so make sure to add a line on top of the last to digits to represent that it is repeating.

a. The rate of change in length of baby grace is 0.75.
b. The linear equation for Baby Grace growth rate in point slope form is y - 20 = 0.75(x - 4)
a. The slope of the line for baby Claire growth is 0.8.
b. Baby girl Claire growth rate is faster than baby girl Grace growth rate.
How to form linear equation and find slope?Let's solve for the growth chart of baby grace.
Therefore,
a.
The rate of change in length of baby Grace can be found as follows:
rate of change = y₂ - y₁ / x₂ - x₁
Hence, using (4, 20)(6, 21.5)
rate of change = 21.5 - 20 / 6 - 4
rate of change = 1.5 / 2
rate of change = 0.75
b . The linear equation in point slope form can be found as follows;
y - y₁ = m (x - x₁)
where
m = slopeTherefore,
y - 20 = 0.75(x - 4)
Let's tackle the growth chart for baby Claire,
a.
slope of the line = y₂ - y₁ / x₂ - x₁
Using (4, 22)(14, 30)
slope of the line = 30 - 22 / 14 - 4
slope of the line = 8 / 10
slope of the line = 4 / 5 = 0.8
b.
Therefore, Baby Claire growth rate is faster than baby Grace.
This is because bay Claire growth rate is 0.8 and baby Grace is 0.75.

The value of a is 30.1
Divide Fraction Definition
The denominators of fractions must match in order to divide them. The numerators' quotient will be the quotient.
The phrase provided is,
a/12 = 30.1/12
We can directly cut the values if the denominator is the same. Since there is a 12 in the denominator on both the right and left sides in this case, remove 12 from both sides.
Thus, a = 30.1
Likewise, you can act in such manner,
a = (30.1 * 12) / 12
a = 30.1
Here, we take the right side of the left side denominator 12 and cancel 12.
Hence, A has a value of 30.1

Given,
Here we have the function
n(x) = -1 -x + 4
And we need to find the value of the function when x takes the values -2, 0 and 5.
To solve this one, then we have to put the value of x on the function and then we have to simplify it in order to get the value of the function.
For that first we have to put the value of x = -2, then we get,
n(-2) = -1 - (-2) + 4
n(-2) = -1 + 2 + 4
n(-2) = -1 +6
n(-2) = 5
Now we have to apply the value of x as 0, then we get the value of function as,
n(0) = -1 - 0 + 4
n(0) = -1 + 4
n(0) = 3
Finally we gave to apply the value of x as 5, then we get the value of n(5) as,

From the equation 3x + 59 = 120, the unit cost of the shirts is $20.33.
What is an equation?An equation is a mathematical statement used to equate two mathematical expressions.
To demonstrate equality, equations use the equation symbol (=).
The total amount spent on new clothes = $120
The number of shirts bought = 3
The cost of the pair of pants bought = $59
Equation of the situation is 3x + 59 = 120,where x = the unit cost of the shirts.
3x + 59 = 120
Subtract 59 from both sides:
= 3x + 59 - 59 = 120 - 59
Simplify both equations:
3x = 61
Divide both sides by 3:
3x/3 = 61/3

What do you mean by congruency?
In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other. Formally speaking, two sets of points are said to be congruent if—and only if—they can be changed into one another by an isometry, which is a combination of rigid movements like translation, rotation, and reflection. This indicates that one item may be exactly aligned with the other object by moving and reflecting it, but not by resizing it. So if we can cut out and then perfectly match up two separate plane figures on a sheet of paper, they are congruent. The paper may be turned over.

6(x-2) = 3x+30
6x-12 = 3x + 30
-3x -3x
3x-12=30
+12 +12
3x=42
~divide by 3 on both sides~
x = 14
Now that we know our x variable, we can substitute 14 into the expression for angle DHG.
6(14-2)
6(12)
72.
Answer:
∠DHG = 72°
Step-by-step explanation:
As ∠DHG and ∠EHF are vertical angles, they are congruent.
What are vertical angles?
Vertical angles are formed when two lines intersect, creating opposite angles. Those opposites are congruent (equal).
Equation:
∠DHG = ∠EHF
[6(x - 2)] = (3x + 30)
Step 1: Distribute 6 through the parentheses.
[tex]\implies 6(x) + 6(-2) = 3x + 30[/tex]
[tex]\implies 6x - 12 = 3x + 30[/tex]
Step 2: Subtract 3x from both sides.
[tex]\implies 6x - 3x - 12 = 30[/tex]
[tex]\implies 3x - 12 = 30[/tex]
Step 3: Add 12 to both sides.
[tex]\implies 3x - 12 + 12 = 30 + 12[/tex]
[tex]\implies 3x = 42[/tex]
Step 4: Divide both sides by 3.
[tex]\implies \dfrac{3x}{3} = \dfrac{42}{3}[/tex]
[tex]\implies \boxed{x = 14}[/tex]
Step 5: Substitute the value of x into ∠DHG to find its measure.
[tex]\implies \angle DHG = 6(14 - 2)[/tex]
[tex]\implies \angle DHG = 6(12)[/tex]
[tex]\implies \angle DHG = \boxed{72^\circ}[/tex]
Therefore, the measure of ∠DHG is 72°.
