The SAA postulate is a condition that is used to prove that two triangles are congruent if they have two pairs of corresponding congruent angles and a pair of non-included congruent sides.

From the information we have in the diagram, we can deduce that:

AC ≅ EC (one pair of congruent sides)

ACB ≅ ECB (one pair corresponding congruent angles)

The 32nd term of the arithmetic sequence AP is computed to be 12.5.

In mathematics, an arithmetic progression (AP) is a list or sequence of numbers in which each term is attained by adding a pattern to the term before it.

Finally, here is the answer to the question;

The following are the numbers in the presented sequence:

0.1,0.5,0.9,1.3, ...........

Because the series contains 32 terms, we must find the 32nd number.

Assume the first term is'a₁' = 0.1.

Assume 'a₂' = 0.5 is the second term.

Assume the third term is 'a₃' = 0.9

'd' is the common difference between two consecutive terms of an AP that are equal.

d = a₂ - a₁  

Put the values in the preceding formula; the 32nd term is

d = 0.5 - 0.1

d = 0.4

The nth term equation is found by the formula;

Substitute the given values in the formula;

a₃₂ = a + (n - 1) d

a₃₂ = 0.1 + (32 - 1)(0.4)

a₃₂ = 0.1 + 12.8 - 0.4

a₃₂ = 12.5

Therefore, the arithmetic sequence's 32nd term value is estimated to be 12.5.

By solving a linear equation, we can see that after 3 hours Ricardo has $61.91

We know that Ricardo has $132.16, and he rents a jet sky that costs $20 plus $16.75 per hour.

So, the cost of renting the jet sky for x hours is given by the linear equation:

C(x) = $20 + x*$16.75

The cost of renting this for 3 hours is:

C(3) = $20 + 3*$16.75 = $70.25

Subtracting this from what Ricardo had:

$132.16 - $70.25 = $61.91

So the correct option is the second one.

The arithmetic sequence AP's 32nd term is estimated to be 127.

An arithmetic progression (AP) in mathematics is a list or sequence of numbers within which each term is acquired by adding a sequence to the term before it.

Finally, the response to the question;

The numbers in the provided sequence are as follows:

34,37,40,43, ...........

There are 32 terms in the series, so we must obtain the 32nd number.

Suppose the first term is 'a₁' = 34.

Suppose 'a₂' = 37 be the second term.

Suppose 'a₃' = 40 be the third term.

The common difference between the two consecutive terms of an AP that are equal is 'd.'

d = a₂ - a₁  

Put the values in the preceding formula; the 32nd term is

d = 37 - 34

d = 3

The nth term equation is now used to calculate.

Substitute all of the values in the formula now.

a₃₂ = a + (n - 1) d

a₃₂ = 34 + (32 - 1)(3)

a₃₂ = 34 + 96 - 3

a₃₂ = 127

Thus, the arithmetic sequence's 32nd term is evaluated to be 127.

By elimination, the solution of the system of equations, r + 3s = 7 and 2r - s = 7, is (r , s) = (4 , 1).

A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.

There are three methods that can be used to solve system of equations.

1. Elimination

2. Substitution

3. Graphing

Using the elimination method, given two equations in r and s, a variable should be eliminated by adding/subtracting the two equations.

First, multiply the first equation by 2.

r + 3s = 7 ⇒ 2r + 6s = 14     (equation 1)

Subtracting the two equations will eliminate the variable r.

2r + 6s = 14     (equation 1)

2r  -   s = 7     (equation 2)

    7s    = 7

s = 1

Substitute the value of s to any of the two equations and solve for r.

2r - s = 7     (equation 2)

2r - 1 = 7

2r = 7 + 1

2r = 8

r = 4

Hence, the solution of the system of equations is (r , s) = (4 , 1).

Answer:

Step-by-step explanation:

In order to determine the relationship between the time and the amount of money in the account, we would calculate the average rate of change.

The average rate of change can be defined as a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.

Mathematically, the slope (average rate of change) can be calculated by using this formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

For Tammy's account, we have:

Points (x, y) = (6, 467) (8, 557)

Average rate of change = (557 - 467)/(8 - 6)

Average rate of change = 90/2

Average rate of change = 45.

As time increases, the amount of money in Tammy's account increases. Also, the rate at which the amount of money in the account is increasing is 45 dollars per month.

First of all, we would determine the increment in 6 months as follows:

Increment = $45 × 6

Increment = $270.

Initial amount = $467 - $270

Initial amount of money = $197.

Based on the number of people going to see the movie and the price of the snacks, the total that Genesis would pay if she bought 6 snacks is $78.

The amount that Genesis would pay if she bought x snacks is 60 + 3x.

The total cost to Genesis can be found as:

= (Number of people going to watch movie x Price of ticket) + (Price per snack x number of snacks)

= (4 people including Genesis x 15) + (3 x 6)

= 60 + 18

= $78

The amount that Genesis would pay if she got x snacks is:

Mr. Sanchez's class sold 45 fruit pies, and Mr. Kelly's class sold 37 bottles of fruit juice.

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

To solve this question, we use the following representations:

x represents the fruit pies

y represents the fruit juice

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

1.89x + 1.56y = 140.13 ---- the total cost

x + y = 82 --- the number of sales

Make x the subject in x + y = 82

So, we have

x = 82 - y

Substitute x = 82 - y in 1.89x + 1.56y = 140.13

1.89(82 - y) + 1.56y = 140.13

Expand

154.98 - 1.89y + 1.56y = 140.13

Evaluate the like terms

-0.33y = -14.85

Divide by -0.33

y = 45

So, we have

x = 82 - y

x = 82 - 45

Evaluate

x = 37

Hence, Mr. Sanchez's class sold 45 fruit pies, and Mr. Kelly's class sold 37 bottles of fruit juice.

Evaluating the expression -4 + 2ab for a = 3 and b = -5 is equal to -34.

An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".

To evaluate an expression or an equation means to substitute a value to the variable and perform the arithmetic operations included.

Given the expression -4 + 2ab, substitute the value of the variable a and the value of variable b.

-4 + 2ab

-4 + 2(3)(-5)

Performing the arithmetic operations, we can have the value of the expression.

-4 + 2(3)(-5)

= -4 + (-30)

= -34

Hence, the expression -4 + 2ab when a = 3 and b = -5 is equal to -34.

Adding -7x both sides,

168-7x ≥ 7x+4y-7x

168 - 7x ≥ 4y

The initial amount and rate of change given a table for a linear function are $332 and $22.5, respectively

The table of linear function represents the given parameter

On the table, we have the following points

(x, y) = (6, 467) and (10, 647)

The rate of change is calculated as

Rate = (y2 - y1)/(x2 - x1)

So, we have

Rate = (647 - 467)/(10 - 2)

Evaluate

Rate = 22.5

This means that the rate of change is $22.5

The initial amount is calculated as

y = m(x - x1) + y1

Where

m = 22.5

So, we have

y = 22.5(x - x1) + y1

Using one of the points, we have

y = 22.5(x - 6) + 467

Set x = 0

So, we have

y = 22.5(0 - 6) + 467

Answer:

MP = 29

Step-by-step explanation:

Given:

MN + NP = MP

17 + 3y = 5y + 9

Find what y =____

17 + 3y = 5y + 9

subtract 9 from both sides

17 - 9 + 3y = 5y + 9 - 9

8 + 3y = 5y

subtract 3y from both sides

8 + 3y - 3y = 5y - 3y

8 = 2y

divided both sides by 2 to get y alone

8/2 = 2y/2

4 = y

Now plug in y to MP to find its length

5(4) + 9 = 20 + 9 = 29

MP = 29

To find NP, plug in y as well

3y = 3(4) = 12

NP = 12

The simplification by combining like terms of 4t-(t + 3t)  is 0.

According to the given question.

We have an expression 4t - (t+3t).

As we know that, like terms are terms whose variables (and their exponents such as the 2 in x2) are the same.  when we combine like terms, such as 2x and 3x, we add or subtract their coefficients.

Since, we have to combine the like terms of the given expression 4t-(t+3t).

Here 4t, t and 3t both are the like terms.

So, we add and subtract coeffcients of t to simplify the given expression.

Therefore, the simplification of 4t - (t + 3t) is given by

4t -( t+ 3t)

= 4t - t -3t

= 4t - 4t
