what value of X makes the model true?

The unknown angle measure is 70 degrees.

We are given that;

The values 40° 70° 110° 180°

Now,

One possible equation to find the unknown angle measure is:

180 - 40 - 70 = ?

This equation is based on the fact that the sum of the angles in a triangle is 180 degrees. To solve for ?, we can subtract 40 and 70 from both sides of the equation:

180 - 40 - 70 = ? - 40 - 70 180 - 110 = ? 70 = ?

The solution is ? = 70 degrees.

Therefore, by equation the answer will be 70 degrees.

When t = 0, the value of n is approximately 3.93 million. The estimated number of people who moved to another state in 2005 is approximately 1.68 million. The predicted number of people who moved to another state in 2014 is approximately 6.81 million.

we need to substitute the given values of t (years since 1990) into the equation n = 0.03t² - 0.6t + 3.93. Let's calculate the values accordingly:

a. When t = 0 (which corresponds to the year 1990), we substitute this value into the equation:

n = 0.03(0)² - 0.6(0) + 3.93

n = 0 + 0 + 3.93

n ≈ 3.93

So, when t = 0, the value of n is approximately 3.93 million. In this context, it means that in the year 1990, around 3.93 million people moved to another state.

b. To estimate the number of people who moved to another state in 2005 (t = 2005 - 1990 = 15), we substitute this value into the equation:

n = 0.03(15)² - 0.6(15) + 3.93

n = 0.03(225) - 9 + 3.93

n = 6.75 - 9 + 3.93

n ≈ 1.68

Therefore, the estimated number of people who moved to another state in 2005 is approximately 1.68 million.

c. To predict the number of people who moved to another state in 2014 (t = 2014 - 1990 = 24), we substitute this value into the equation:

n = 0.03(24)² - 0.6(24) + 3.93

n = 0.03(576) - 14.4 + 3.93

n = 17.28 - 14.4 + 3.93

n ≈ 6.81

Hence, the predicted number of people who moved to another state in 2014 is approximately 6.81 million.

The probability of just thunder is 0.196.

We have,

The probability of rain P(A) = 1/2

The probability of thunder and raining P(A ∩ B) = 1/3

The probability of rain and thunder P(A U B) = 11/30

Now,

Using the addition rule of probability.

P(A U B) = P(A) + P(B) - P(A∩B)

Substituting.

11/30 = 1/2 + P(B) - 1/3

11/30 - 1/2 + 1/3 = P(B)

P(B) = 0.196

Answer: 4:20 and 13:65

Step-by-step explanation: First one is 4 x 5 and second one you would do 65/5

The volume of small solid is 24 cm³ and volume of big solid is 216 cm³.

Given that

Height of small solid = 4 cm = h₁

Width of small solid = 2 cm = w₁

Length of small solid = 3 cm = L₁

Width of big solid = 6 cm = w₂

Let,

Height of small solid = h₂

Length of small solid = L₂

Since we know that volume of solid  = length x width x height

Therefore,  volume of small solid = 4x2x3 = 24 cm³

Since both the solids are similar,

So,

⇒ w₁/w₂ = h₁/h₂

⇒     2/6 = 4/h₂

⇒     h₂ = 12 cm

Also,

w₁/w₂ = L₁/L₂

⇒2/6 = 3/L₂

⇒    L₂= 9 cm

Hence , the volume of big box = 6x12x9

                                                   = 216 cm³

Answer:

Yes, (s + t)^2 is equivalent to s^2 + 2st + t^2. This can be shown through the process of expanding the expression (s + t)^2 using the FOIL method (multiplying first, outer, inner, and last terms).

First, we can rewrite (s + t)^2 as (s + t)(s + t).

Now, we do the multiplication and combine like terms:

s*s + s*t + t*s + t*t

s^2 + st + st + t^2

s^2 + 2st + t^2

The correct answer to the fraction task is 3/5 + 1/2 = 11/10 expressed as a fraction and 4/7 is incorrect answer

The pupil made an error in their addition of 3/5 and 1/2, resulting in an incorrect answer of 4/7.

To solve the task correctly, we need to find a common denominator for 3/5 and 1/2.

The least common multiple of 5 and 2 is 10, so we can rewrite the fractions with a denominator of 10 as follows:

3/5 = 6/10

1/2 = 5/10

Now we can add the fractions:

6/10 + 5/10 = 11/10

Hence, the correct answer to the fraction task is 3/5 + 1/2 = 11/10 expressed as a fraction.

The slope of the line passing through the given points is -2.5.

To find the slope of a line passing through two points, we need to use the formula:

Slope = (Change in y) / (Change in x

We can choose any two points from the given table to find the slope of the line. Let's choose the points (4, 19) and (6, 14).

Change in y = 14 - 19 = -5

Change in x = 6 - 4 = 2

Slope = (-5) / 2 = -2.5

Therefore, the slope of the line passing through the given points is -2.5.

The slope of a line represents the steepness of the line. If the slope is positive, the line is increasing as we move from left to right. If the slope is negative, the line is decreasing as we move from left to right. A slope of 0 represents a horizontal line, while an undefined slope represents a vertical line.

In this case, the slope of -2.5 indicates that the line is decreasing at a moderate rate as we move from left to right. The higher the absolute value of the slope, the steeper the line.

It is important to note that the slope is constant for any two points on a straight line. Therefore, we can choose any other two points from the table to find the slope, and we will get the same result.
