Answer:

x = 20

Step-by-step explanation:

Since the triangles are congruent then corresponding angles are congruent, that is

∠ A = ∠ D , thus

3x - 10 = 2x + 10 ( subtract 2x from both sides )

x - 10 = 10 ( add 10 to both sides )

x = 20

Answer:

never

Step-by-step explanation:

Any triangle can never be a parallelogram because it only has three sides.

Step-by-step explanation:

A graphing calculator can be helpful for questions of this nature. The attached shows the center is (-9, -7) and the radius is 5.

_____

You can separate the x- and y- terms and complete the square for each.

  (x^2 +18x) +(y^2 +14y) = -105

Do that by adding the square of half the linear term.

  (x^2 +18x +9^2) +(y^2 +14x +7^2) = -105 +81 +49

  (x +9)^2 +(y +7)^2 = 25

Compared to the standard form equation ...

  (x -h)^2 +(y -k)^2 = r^2 . . . . . . . center (h, k), radius r

We see that the given circle has a center of (-9, -7) and a radius of 5.

Answer:

Option B. 3 liters

Step-by-step explanation:

First, we shall determine the total volume of soup that Mei have. This is illustrated below:

Mei have 8 jars of soup containing 300mL each. Therefore, she has a total of = 8 x 300mL = 2400mL.

Next, we shall convert 2400mL to litres (L). This can be obtain as follow:

1000mL = 1L

Therefore, 2400mL = 2400/1000 = 2.4L

Mei have 2.4L of soup.

Since the total volume of the soup that Mei have is 2.4L, she will be needing a minimum of 3L pot to heat up all the soup.

the 3rd answer choice is the correct one

Step-by-step explanation:

Let's actually find the inverse function:

1.  Replace 'f(x)' with 'y:'  y = 2x - 10

2. Interchange x and y:  x = 2y - 10

3.  Solve this result for y:  2y = x - 10, or  y =  (1/2)x - 5

Thus, the 3rd answer choice is the correct one.

Step-by-step explanation:

Do tell me if I'm wrong please.

The value of each digit in a number is known as the place value. The number of hundredths that 40 thousandths will have is 4.

The value of each digit in a number is known as the place value. The 5 in 350, for example, represents 5 tens, or 50, whereas the 5 in 5,006 represents 5 thousand, or 5,000. It is critical that children that while a digit can be the same, its value is determined by its position in the number.

Identification of the place value of a digit in a number:

A thousandth is the (1/1000)th part of something, while a hundredth is the (1/100)th part of something.

Let the number of hundredths be x. Therefore, the number of hundredths can be written as,

40(1/1000) = x(1/100)

0.04 = x/100

x = 4

Hence, the number of hundredths that 40 thousandths will have is 4.

Answer:

23 años

Step-by-step explanation:

Para resolver la situación, consideremos que x es la edad de la persona. Sabemos que dentro de seis años esta tendrá el doble de la edad que tenía hace cuatro años. La edad dentro de 6 años se puede expresar como x+6 y esto será igual al doble de la edad que tenía hace cuatro años, lo que se puede expresar como 2(x-4). De acuerdo a esto:

x+6=2(x-4)

x+6=2x-8

6+8=2x-x

x=14

Ahora que sabemos que la edad de la persona es 14 años, le sumamos 9 y esto da como resultado 23 y esta es la edad que la persona tendrá en 9 años.

Answer:

{ x : x = 2^n -1 , n ∈ N}

Where N is the set of natural numbers

Step-by-step explanation:

Mathematically, we can rewrite each term in the set as follows;

1 = 2^1 - 1

3 = 2^2 -1

7 = 2^3 -1

15 = 2^4-1

31 = 2^5-1

63 = 2^6 -1

so we can conclude that the nth term is 2^n -1

So writing this in set builder notation, we have;

{ x : x = 2^n -1 , n ∈ N}

Where N is the set of natural numbers

Answer:

B. p > 12.80(160) + 8235.

Step-by-step explanation:

Since he wants to make a profit, the price he will need to receive for his crop will have to exceed his costs. So, the equation would use the > sign rather than the >= sign.

He harvests crops for $12.80 per acre, with 160 acres. That would be 12.80(160).

He is spending $8235, which adds to the costs of harvesting.

So, the answer will be B. p > 12.80(160) + 8235.

Answer:

$13,724

Step-by-step explanation:

From the above question, we are given the following values:

Principal = P = $12,000

Interest = r = 2.25% = 0.0225

Compounded semi annually = n = 2

Time (t) = 6 years

From the question, we understand that we are to find the total (full) Amount Karen withdrew.

The formula to use to calculate the Total Amount of money given that this is a compound interest question is:

Total(full) Amount = P( 1 + r/n) ^n/t

= $12,000( 1 + 0.0225/2) ^2×6

= $12,000(1.01125)^12

= $13724.093289

Approximately to the nearest cent

≈ $13,724

Therefore, Karen withdrew $13,724 from the account.

Karen Gaines invested $14000 in a money market account with an interest rate of 2.75% compounded semiannually. Six years later, Karen withdrew the full amount to put toward the down payment

Round to the nearest cent as needed.)

Answer:

Answer:

First, we find the square of the difference of the z values provided and sum them up giving us a value of 4.997956. We, therefore, calculate the sum of the sample mean given the number of samples to be 5 which gives us zero(0).

To calculate the standard deviation we use the formula that takes the square root of the inverse of the number of samples (n)*(the summation of the square of the difference between the sample and the mean which gives us 1.

*Step-by-step explaination

Given z3= -1.101, (z3 minus mean of z3)^2= 1.212201

Given z4= -0.944, (z4 minus mean of z4)^2=0.891136

Given z9= -0.157, (z9 minus mean of z9)^2= 0.024649

Given z14= 0.629, (z14 minus mean of z14)^2= 0.395641

Given z20= 1.573, (z20 minus mean of z20)^2= 2.474329

Therefore the summation of all Z values = Zero(0)

Also, the summation of (z values minus the mean of z values)^2= 4.997956

Therefore where n =5,

The sample mean of z values is given by the summation of z values divided by n = Zero (0)

To calculate standard deviation we use the formula that takes the square root of the inverse of the number of samples (n)*(the summation of the square of the difference between the sample and the mean which gives us 1.

Using it's concepts, it is found that:

In this problem, the observations are: -1.101, -0.944, -0.157, 0.629 and 1.573.

Hence:

[tex]M = \frac{-1.101 - 0.944 - 0.157 + 0.629 + 1.573}{5} = 0[/tex]

The mean of the z-scores is 0.

[tex]S = \sqrt{\frac{(-1.101-0)^2 + (-0.944-0)^2 + (-0.157-0)^2 + (0.629-0)^2 + (1.573-0)^2}{5}} = 1[/tex]

The standard deviation of the z-scores is 1.

Answer:

{ - 2, 10 }

Step-by-step explanation:

Given

x² - 8x = 20

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 4)x + 16 = 20 + 16, that is

(x - 4)² = 36 ( take the square root of both sides )

x - 4 = ± [tex]\sqrt{36}[/tex] = ± 6 ( add 4 to both sides )

x = 4 ± 6

Thus

x = 4 - 6 = - 2
