A rhombus is a two dimensional shape which consists of four equal sides with opposite side being parallel and opposite angles being equal.

Given is a rhombus ABCD.

Opposite angles are equal.

∠A = ∠C and ∠B = ∠D

Diagonal of a rhombus bisects the angles through which it pass.

AC bisects angles A and C.

So, ∠BAC = ∠BCA

Already, we have ∠BAC = (3x + 10)°.

So, ∠BCA = (3x + 10)°

Also, the diagonal BD bisects the angle B and D.

∠B = x + x = 2x

We have that sum of interior angles of a triangle is 180°.

Consider ΔABC.

∠BAC + ∠BCA + ∠ABC = 180°

(3x + 10) + (3x + 10) + 2x = 180

8x + 20 = 180

8x = 160

x = 20

Let us understand this with the help of an example.

To find -2 × 5 using integer tiles, follow these steps:

1. Take two red tiles to represent -2. 2.

Take five yellow tiles to represent 5. 3.

Combine the two sets of tiles. 4.

The final count of the tiles will be negative as we had negative tiles in the beginning. Hence the product will be -10.

To find -2 × 5 using a number line, follow these steps:

To compare the 3-month and 12-month moving average forecasts using the mean absolute deviation (MAD) criterion, we need to calculate the MAD for each model and then compare them. The MAD is a measure of the average magnitude of the forecast errors, and a lower MAD indicates a better forecast.

To calculate the MAD for the 3-month moving average model, we need to first calculate the forecasted values for each month by taking the average of the unemployment rates for the previous 3 months. For example, the forecasted value for April 2018 would be the average of the unemployment rates for January, February, and March 2018. We then calculate the absolute deviation between the forecasted value and the actual value for each month, and take the average of those deviations to get the MAD for the 3-month moving average model.

We can repeat this process for the 12-month moving average model, but instead of taking the average of the previous 3 months, we take the average of the previous 12 months.

Once we have calculated the MAD for both models, we can compare them to determine which model yields better results. Generally, a lower MAD indicates a better forecast. However, it is important to note that the MAD criterion only considers the magnitude of the forecast errors and does not take into account the direction of the errors (i.e., overestimation versus underestimation).

Answer:

Y-coordinate of the vertex: y = -7

Step-by-step explanation:

We are given the following quadratic equation, y = x² + 6x + 2, where a = 1, b = 6, and c = 2.

The value of "a" (leading coefficient) provides the following important details about the graph of the given quadratic equation:

The given prompt also states that we can determine the x-coordinate of the vertex by using the follwing formula:

     \(\displaystyle\mathsf{x\:=\:\Bigg[ \:\frac{-b}{2a}\:\Bigg]}\)

Using the given values from our quadratic equation, where a = 1, and b = 6, simply substitute these into the formula:

    Quadratic equation: y = x² + 6x + 2

     a = 1, b = 6, and c = 2.

     \(\displaystyle\mathsf{x\:=\:\Bigg[ \:\frac{-b}{2a}\:\Bigg]\:=\:\frac{-6}{2(1)}\:=\:\frac{-6}{2}\:=\:-3}\)

Therefore, the value of the x-coordinate is -3.

Now that we have the value of our x-coordinate, simply substitute this into the given quadratic equation to find its corresponding y-coordinate:

Quadratic equation: y = x² + 6x + 2

     ⇒   y = (-3)² + 6(-3) + 2

     ⇒   y = 9 - 18 + 2

     ⇒   y = - 7

Hence, the value of the y-coordinate is -7, making our vertex occurring at point (-3, -7). The attached screenshot is the graph of y = x² + 6x + 2, where it shows that the vertex is the minumum point on the graph.

Answer:

3 times 1600 = 4800

Step-by-step explanation:

Scale ratios are used to show the relationship between objects, where one of the objects is the enlarged version of the other.

The actual length of the dinning room is 120 inches

Given that:

\(A_1 \to\) the actual area

\(A_2 \to\) area of the blueprint

So, we have:

\(A_1: A_2 = 1600 : 1\)

Rewrite as:

\(A_1: A_2 = 40 \times 40 : 1 \times 1\)

Apply the formula of area of rectangle

\(L1 \times W_1: L_2 \times W_2 = 40 \times 40 : 1 \times 1\)

Given that:

\(L_2 = 3\)

The equation becomes

\(L1 \times W_1: 3\times W_2 = 40 \times 40 : 1 \times 1\)

Express the ratio as a fraction

\(\frac{L1 \times W_1}{3\times W_2} = \frac{40 \times 40}{ 1 \times 1}\)

Split

\(\frac{L1 }{3} \times \frac{W_1}{W_2} = \frac{40}{1} \times \frac{40}{ 1}\)

By comparison:

\(\frac{L1 }{3}= \frac{40}{1}\)

\(\frac{L1 }{3}= 40\)

Multiply both sides by 3

\(L_1 = 3 \times 40\)

\(L_1 = 120\)

Hence, the actual length of the dinning room is 120 inches

If the paint gallon cost $12 and carton cost is $5 , then the amount saved per gallon buying the larger can is $8  .

We know that 1 gallon is = 4 quarts. So , a one-gallon can is equal to four one-quart cans.

To buy one gallon of paint, we need to buy 4 one-quart cans.

Each one-quart can costs $5, so 4 one-quart cans will cost:

⇒ 4 × $5 = $20 ,

Now, the cost of one gallon of paint if it is bought in one one-gallon can.

⇒ One one-gallon can costs $12.

Answer:

Step-by-step explanation:

Step 1 - Expand the brackets:

-2(1 - 5x) = 4 - 4(-2x)

-2 - (-5x) = 4 - (-8x)

-2 + 10x = 4 + 8x

Step 2 - Subtract 8x from both sides:

-2 + 10x - 8x = 4 + 8x - 8x

-2 + 2x = 4

Step 3 - Add 2 to both sides and isolate 2x:

-2 + 2x + 2 = 4 + 2

2x = 6

Step 4 - Divide by two:

2x ÷ 2 = 6 ÷ 2

Answer:

\(m\widehat{MP}=118^{\circ}\)

Step-by-step explanation:

In any circle, the measure of an inscribed angle (an angle created when the intersection of two chords is on the circle) is equal to half of the arc it forms. In this case, \(\angle MPN\) is an inscribed angle that forms \(\widehat{MN}\). Therefore, the measure of arc MN must be twice the measure of angle MPN:

\(m\widehat{MN}=2\cdot m\angle MPN,\\m\widehat{MN}=2\cdot 31^{\circ}=62^{\circ}\)

Since we want to find the measure of arc MP, we need to know that there are 360 degrees in a circle. Since \(\overline{PN}\) is a diameter of the circle (line that has two endpoints on the circle and that passes through the center of the circle), each side of \(\overline{PN}\) must be 180 degrees.

Therefore, we have:

\(m\widehat{MN}+m\widehat{MP}=180^{\circ},\\62^{\circ}+m\widehat{MP}=180^{\circ},\\m\widehat{MP}=\boxed{118^{\circ}}\)
