many trees have concentric rings that can be counted to determine the trees age. each ring represents one years growth. a maple tree with a diameter of 12 inches has 32 rings. if the tree continues to grow at about the same rate, how many rings will the tree have when its diameter is 20 inches?
Answer:
adout 53 Years old
Step-by-step explanation:
2. = 6=12=32. 32/2= 16
5.3=16=32= 16/3=5.333...
5.3x10=S3.3
so adout 53 Years old
Based on the tree's current growth rate of 2.67 rings per inch, if it continued to grow at the same rate, a maple tree with a diameter of 20 inches would have around 53 rings.
Explanation:The tree's growth can be understood as the relation between its diameter and the number of its concentric rings. In this case, we know that a maple tree with a diameter of 12 inches has 32 rings. This means that the tree grows approximately 2.67 rings per inch (32 rings / 12 inches = 2.67 rings per inch). So, assuming the tree continues to grow at the same rate, when the tree's diameter is 20 inches, it should have around 53 rings (20 inches * 2.67 rings per inch =~ 53 rings).

Answer:
[tex]\$452.80[/tex]
Step-by-step explanation:
we know that
To find out how much money did they earn in total sum the product of the hours at regular pay by $8.20 plus the product of the hours at overtime pay by ($8.20+$2.20), all multiplied by the number of employees
so
[tex][(10)(8.20)+(3)(2.20+8.20)](4)[/tex]
[tex][82+31.2](4)[/tex]
[tex][113.2](4)[/tex]
[tex]\$452.80[/tex]
Answer:
$ 452.80
Step-by-step explanation:
Given,
The regular payment per hour for each employee = $ 8.20,
∵ Number of regular hours = 10,
Thus, wages for each employee in regular hours = 10 × 8.20 = $ 82,
Also, the overtime charges per hour = 8.20 + 2.20 = $ 10.4,
∵ Number of overtime hours = 3,
Thus, the overtime charges for each employee = 3 × 10.4 = $ 31.2,
∴ Total earning of each employee = 82 + 31.2 = $ 113.2,
Now, number of employees = 4,
Hence, the total earning of all employees = 4 × 113.2 = $ 452.8

If the expression x-3 has a value of -5,then which of the following represents the value of 3x-9
Answer:
-15
Step-by-step explanation:
Italics by itself are comments, italics and underlines are helpful rules, bold highlights little facts.
x-3=-5 : since the expression 'x-3' is being assigned the value '-5'
We then isolate or leave the variable 'x' on one side, usually the left-hand side and move all constants (numbers without letters attached such as 3, 4, 5..etc.) and variables (letters such as x, y, a, b..etc.) that do not have 'x', to the right-hand side of the equality symbol (=). This also includes terms such as 5x, -2y, 50z..etc.
(Remember that the opposite of multiplication is division and vice versa and the opposite of addition is subtraction and vice versa).
To do that, we add 3 to both sides of the equation, because the opposite of subtraction is addition (in this case 3 is being subtracted by x, therefore in order to cancel 3 on the left, we do the opposite of the operation). By doing this, we effectively cancel 3 on the left and bring it to the right-hand side. After all, 3 cannot be in two places at once (well not in this equation).
x=-5+3 which is equal to -2.
Hence, x=-2
Now that we know what 'x' is we can work on the other expression: 3x-9
Substitute the value for 'x' (-2 is what we got) into the 'x' in the expression.
3(-2)-9=?
(Remember that a positive number multiplied by a negative number will ALWAYS be a negative number. In other words, (+) × (-) = (-). Yes, this also includes a negative number multiplied by a positive number).
Therefore, 3×(-2) will equal -6.
-6-9=-15
Hence, 3x-9=-15.
To make sure your answer is correct, do the equation backwards. Add 9 to -15 which would then give you -6.
Here's how that looks: 3x-9 (+9)= -15 (+9).
You would then be left with 3x=-6.
If you remembered the rule typed previously, I said in order to isolate 'x' we do the opposite of the operation. 3x means '3' multiplied by 'x', therefore the opposite of multiplication is division:
3x(÷3)=-6(÷3) ----> 3 divided by 3 equals 1. Anything multiplied by 1 will be equal to itself (x*1= x)
(An asterisk can also symbolise multiplication).
Therefore when 3x is divided by 3, the constants would cancel each other out, 1 would be left looking like this: 1x=... and 1x is the same as x by itself.
-6 divided by 3 is equal to -2 (a positive divided by a negative will always be negative and vice versa).
Hence, x=-2.
The value of the expression 3x - 9 will be - 15 if x - 3 is -5.
What is a numerical expression ?A numerical expression is in the form of numbers and their operations.
According to the given question the expression x-3 has a value of -5.
We have to determine the value of 3x - 9.
Let us solve for x in the equation
x - 3 = -5.
x = -5 + 3.
x = -2.
Putting this value of x in 3x - 9 would result in
3(-2) - 9
= -6 -9
= -15.
This can also be done in a different approach
x - 3 = - 5.
3x - 9 will be if we observe the equation has been multiplied by 3
3x - 9.

Step-by-step explanation:
trust me:)
The profit gotten at each level of production of the bicycles are respectively; -$30, $3, $40, $70, $90, $90, $80
How to Calculate Profit from production
From the attached table, we see three columns showing respectively;
Column 1; Units of bicycles produced per day
Column 2; Total Cost of the Units of bicycles produced per day
Column 3; Total revenue from the sale of the units of bicycles produced per day.
Now, to find the profit we will just subtract the cost of producing the given number of units from the total revenue from the sale of that specific unit produced.
For the level of 1 bicycle produced; Profit = $50 - $80 = -$30
For the level of 2 bicycles produced; Profit = $100 - $97 = $3
For the level of 3 bicycles produced; Profit = $150 - $110 = $40
For the level of 4 bicycles produced; Profit = $200 - $130 = $70
For the level of 5 bicycles produced; Profit = $250 - $160 = $90
For the level of 6 bicycles produced; Profit = $300 - $210 = $90
For the level of 7 bicycles produced; Profit = $350 - $270 = $80

Two minor league baseball players got a total of 390 hits. Washington had 16 more hits than Sanchez. Find the number of hits for each player.
Washington had
hits. Sanchez had
hits.
Answer:
Sanchez had 179 hits, while Washington had 211 hits. Hope this helps!
Final answer:
To solve the problem, we set up two equations: W = S + 16 and W + S = 390. By substituting the first equation into the second, we found that Sanchez had 187 hits, and Washington had 203 hits.
Explanation:
The question involves determining the number of hits for each player given the total number of hits and the difference in hits between the two players. We can set up a system of equations to solve for the number of hits for each player. Let's denote the number of hits by Washington as W and the number of hits by Sanchez as S.
According to the problem, we have two relationships:
Washington had 16 more hits than Sanchez: W = S + 16
The total number of hits is 390: W + S = 390
We can substitute the first equation into the second to solve for S.
S + (S + 16) = 390
S + S = 390 - 16
2S = 374
S = 374 / 2
S = 187
Now we plug the value of S back into the first equation to solve for W:
W = 187 + 16
W = 203
Therefore, Washington had 203 hits and Sanchez had 187 hits.

Find the value of x if R is the midpoint of QS QR=5x-7 and QS=96
Answer: The required value of x is 11.
Step-by-step explanation: Given that R is the midpoint of the line segment QS, where
QR=5x-7 and QS=96.
We are to find the value of x.
Since the point R is the midpoint of the segment QS, so we must have
[tex]QR=SR=\dfrac{1}{2}QR\\\\\\\Rightarrow QR=\dfrac{1}{2}QS\\\\\\\Rightarrow 5x-7==\dfrac{1}{2}\times96\\\\\Rightarrow 5x-7=48\\\\\Rightarrow 5x=48+7\\\\\Rightarrow 5x=55\\\\\Righatrrow x=\dfrac{55}{5}\\\\\Rightarrow x=11.[/tex]
Thus, the required value of x is 11.
If R is the midpoint of QS, then x = 11.
We have,
If R is the midpoint of QS, then QR is equal in length to RS.
Therefore:
QR = RS
Given that QR = 5x - 7 and QS = 96, we can set up an equation:
5x - 7 = QS/2
Now, plug in the value of QS:
5x - 7 = 96/2
5x - 7 = 48
Add 7 to both sides:
5x = 48 + 7
5x = 55
Now, divide both sides by 5 to isolate x:
x = 55 / 5
x = 11
So, the correct value of x is 11.
Thus,
If R is the midpoint of QS, then x = 11.

c= Chris's score
m= Mike's score
c+m=39 we know from the equation that their scores
add up to 39, so this equation is a good starting
point.
c+2(c+3)=39 we also know that Mike's score is twice the sum of Chris's
score and 3 so we can substitute that in for his score.
now we can solve.
c+2c+6=39 distribute
3c+6=39 combine like terms
