Answer:
6.5 cm < x < 14.5 cm
Step-by-step explanation:
The length of the side of a triangle must be greater than the difference of the lengths of the other two sides and less than the sum of the other two sides.
Difference: 10.5 cm - 4 cm = 6.5 cm
Sum: 10.5 cm + 4 cm = 14.5 cm

2a+c=162.97
how do you use the elimination method for this
When 'a' is 10, 'c' is approximately 142.97. You can repeat this process for different values of 'a' to find corresponding values of 'c'. Keep in mind that there are infinitely many solutions to this equation
To use the elimination method to solve the equation 2a + c = 162.97, we need another equation with the same variables. However, as there is only one equation given, we cannot apply the elimination method directly.
The elimination method typically involves adding or subtracting equations to eliminate one of the variables, resulting in a new equation with only one variable. Since we have only one equation, we don't have the opportunity to eliminate variables using another equation.
In this case, we can solve the given equation directly by isolating one variable in terms of the other. Let's solve for 'c':
2a + c = 162.97
Rearrange the equation to isolate 'c':
c = 162.97 - 2a
Now, we have an expression for 'c' in terms of 'a'. This equation represents a line in the 'a-c' coordinate plane. We can choose any value for 'a', substitute it into the equation, and calculate the corresponding 'c' value.
For example, let's say we choose 'a' = 10:
c = 162.97 - 2(10)
c = 162.97 - 20
c = 142.97
So, when 'a' is 10, 'c' is approximately 142.97.
You can repeat this process for different values of 'a' to find corresponding values of 'c'. Keep in mind that there are infinitely many solutions to this equation since we have one equation and two variables.

The Residual is 0.944 kg.
What is Residual ?The discrepancy between a response variable's observed value and its expected value as predicted by the regression line.
Given:
Residual is typically defined as actuals minus predicted.
The prediction is calculated from

1493600÷8 i need full steps
When 1,493,600 is divided by 8 the quotient is 186,700.
To divide 1,493,600 by 8, you can follow these steps:
We have to write down the dividend (1,493,600) and the divisor (8).
Now start with the largest place value in the dividend (the leftmost digit) and perform the division.
Divide 1 by 8. Since 1 is smaller than 8, you move to the next digit.
Bring down the next digit (4) and combine it with the previous quotient (0). This gives you 04.
Divide 4 by 8. Since 4 is smaller than 8, you move to the next digit.
Bring down the next digit (9) and combine it with the previous quotient (0). This gives you 09.
Divide 9 by 8. The quotient is 1, and the remainder is 1.
Bring down the next digit (3) and combine it with the remainder (1). This gives you 13.
Divide 13 by 8. The quotient is 1, and the remainder is 5.
Bring down the next digit (6) and combine it with the remainder (5). This gives you 56.
Divide 56 by 8. The quotient is 7, and there is no remainder.
Bring down the next digit (0) and combine it with the quotient (7). This gives you 70.
Divide 70 by 8. The quotient is 8, and there is no remainder.
There are no more digits to bring down, and the division is complete.
The quotient is the result of the division. In this case, 1,493,600 divided by 8 is equal to 186,700.
Therefore, the result of 1,493,600 ÷ 8 is 186,700.

An individual is baking 3 batches of cookies. They used 1.8 oz. of vanilla in one batch of the cookies, 1.25 oz. of vanilla in the second batch and .95 oz. in the third batch. Convert these decimals into fractions, and then put them in ascending order.
Answer:
19/20 , 1 1/4 , 1 4/5
Step-by-step explanation:
1.8 = 1 4/5 (fraction)
1.8 converts to 18/10. This can be simplified twice, firstly by making it 9/5 since both 18 and 10 are divisible by two, but can be simplified further to 1 4/5
1.25 = 1 1/4 (fraction)
1.25 converts to 125/100. This can be simplified to 5/4 or 1 1/4
0.95 = 19/20 (fraction)
0.95 converts to 95/100. This can be simplified to 19/20

What is factoring?A polynomial expression can be represented as a product of other, smaller polynomial expressions through the algebraic process of factoring. The process of factoring can be used to simplify expressions and solve problems. A polynomial equation's roots can be found by factoring, as can the common factors in an expression that can be eliminated. Factoring occasionally enables us to spot trends and connections between several expressions.
Depending on the kind of polynomial and the degree of the terms involved, there are several ways to factor. S
For the given expression \((12y^7u^2-32y^5u^6+15y^7u^6) / (-4y^2u^5)\) factor the common term.

The altitude of an airplane is decreasing at a rate of 40 feet per second. What is the change in altitude of the airplane over a period of 26 seconds?
Answer:
-1040 feet
Step-by-step explanation:
Since the altitude decreases at 40 feet per second, we can find the change in altitude by multiplying -40 by the number of seconds:
So, multiply -40 by 26:
-40(26)
= -1040
So, the change in altitude will be -1040 feet

What is Iinear equatiοn?A Iinear equatiοn is a mathematicaI equatiοn that describes a straight Iine in a twο-dimensiοnaI pIane.
Let the first term οf the Iinear sequence be represented by 'a' and the cοmmοn difference be represented by 'd'. Then, we have:
The sum οf the first 21 terms:
S21 = (21/2) * [2a + (21-1)d] = 28
The sum οf the first 28 terms:
S28 = (28/2) * [2a + (28-1)d] = 21
SimpIifying these equatiοns, we get:
42a + 420d = 28 -----(1)
56a + 1540d = 21 -----(2)
MuItipIying equatiοn (1) by 2 and subtracting it frοm equatiοn (2), we get:
112d = -35
d = -35/112
Substituting this vaIue οf d in equatiοn (1), we get:
42a - (35/8) = 28
42a = 329/8
a = (329/8) * (1/42) = 329/336
Therefοre, the nth term οf the sequence is given by:
an = a + (n-1)d
an = (329/336) + (n-1)(-35/112)
We want tο find the term in the sequence that is equaI tο 0, sο we set an = 0 and sοIve fοr n:
0 = (329/336) + (n-1)(-35/112)
35n = 329/8 + 35/112
35n = 343/8
n = 49/5
Therefοre, the term in the sequence that is equaI tο 0 is the 49/5th term.
Tο find the sum οf the terms preceding this term, we need tο find the sum οf the first (49/5 - 1) = 44/5 terms. This can be fοund using the fοrmuIa fοr the sum οf the first n terms οf an arithmetic sequence:
Sn = (n/2) * [2a + (n-1)d]
S44/5 = (44/10) * [2(329/336) + (44/5 - 1)(-35/112)]

Payton starts a lemonade stand for the summer. She thinks that she should be able to operate her business for 14 weeks. The table shows the expenses and revenue after 1 week.
Item Expenses Revenue
Cups $5
Lemonade $6
Ice $7
Income $45
Based on this, how much money will Payton make during the 14 weeks?
$__
Payton will make money after 14 weeks is $378.
What is income and expenses?Income is the money your business takes in and expenses are what it spends money on. Your net income is generally your revenue, or all the money coming into your business, minus all of your expenses.
For the given situation,
Item Expenses Revenue after 1 week
Number of Cups = $5
Number of Lemonade = $6
Number of Ice = $7
Total revenue, Income = $45
Formula to find the net income,
Net Income = Total Revenue - Total Expenses
⇒ Net Income = \(45 - ( 5+6+7 )\)
⇒ Net Income = \(27\)
Thus net income for 14 weeks = \(14\) × \(27\)
⇒ \(378\)
Hence we can conclude that Payton will make money after 14 weeks is $378.
