The height of the painting in the scale drawing is approximately 5.8 centimeters (rounded to the nearest tenth).

To find the height of the painting in the scale drawing, we can set up a proportion using the given scale.

Given:

Scale: 2 centimeters represent 9 inches

Real height of the painting: 26 inches

Height in the scale drawing: ?

Let's set up the proportion:

2 centimeters / 9 inches = x centimeters / 26 inches

To solve for x (the height in the scale drawing), we can cross-multiply and then divide:

2 centimeters * 26 inches = 9 inches * x centimeters

52 centimeters = 9x

Dividing both sides by 9:

x = 52 centimeters / 9

x ≈ 5.8 centimeters

Answer: (1) Measure of angle K = x degrees

(12) Measure of angle L = (5x) degrees

(3) Measure of angle k + Measure of angle L + Measure of angle N = 180 degrees

Step-by-step explanation: First of all, what we have is a triangle, and one of the properties of a triangle is all three angles add up to 180 degrees. This simply means that the addition of angles K and L and N would be equal to 180 degrees.

The question states that angle K is represented as x degrees, and angle L is 5 times the measure of angle K. Therefore, if K is x degrees, then L is 5 times x, which becomes 5x degrees. Also, angle N is given as 16 degrees less than 8 times the measure of angle K (x degrees). Eight times the measure of angle K is given as 8x. Sixteen degrees less than 8x would now become, 8x - 16 (degrees). Therefore, the angles have been derived as;

Angle K = x degrees

Angle L = 5x degrees

Angle N = 8x - 16 degrees

Having known that one of the properties of any triangle is all angles adding up to 180 degrees, we can now derive the following equation;

x + 5x + 8x - 16 = 180

14 x - 16 = 180

Add 16 to both sides of the equation

14x = 196

Divide both sides of the equation by 14

x = 14

Therefore, angle K = 14 degrees (x), angle L = 70 degrees (5x) and angle N = 96 degrees (8x - 16)

*14 + 70 + 96 = 180*

Answer:

k - 2 = 4d - 8

d + 1 = 4d - 8

Step-by-step explanation:

Daniel's age = d

Kevin's age = k

Given that, k = d + 3 -------------- (1)

Two years ago, the age of Daniel = d - 2

Two years ago, the age of Kevin = k - 2

Since,  two years ago, Kevin was 4 times as old as

Daniel, k - 2 = 4(d - 2)

Opening the bracket,

k - 2 = 4d - 8

Since the value of k is d + 3 (see (1))

d + 3 - 2 = 4d - 8

d + 1 = 4d - 8

(I am just giving the answer cause I LOVE Linear Equation )

1 + 8 = 4d - d

9 = 3d

9/3 = d

3 = d

Therefore, Daniel's present age is 3 and Kevin's present age = 6

Given:

The gradient of the line passing through A(2,3), B(k,7) is \(\dfrac{2}{3}\).

To find:

The value of k.

Solution:

The gradient or slope of a line is:

\(m=\dfrac{y_2-y_1}{x_2-x_1}\)

The gradient of the line passing through A(2,3), B(k,7) is \(\dfrac{2}{3}\). So,

\(\dfrac{2}{3}=\dfrac{7-3}{k-2}\)

\(\dfrac{2}{3}=\dfrac{4}{k-2}\)

On cross multiplication, we get

\(2(k-2)=4(3)\)

\(2k-4=12\)

\(2k=12+4\)

\(2k=16\)

Divide both sides by 2.

\(k=\dfrac{16}{2}\)

\(k=8\)

Therefore, the value of k is 8.

The interval (461.7, 598.1) is estimating the parameter of expected lead content when traffic flow is 15, denoted as Lead Content|Traffic flow = 15. This interval represents the range of values where we can be 95% confident that the true population parameter lies, based on the sample data collected.

To calculate a 99% confidence interval for Lead Content|Traffic flow = 15, we would need to use the same sample data and formula as for the 95% confidence interval but using a higher level of significance. Assuming the underlying assumptions of normality, independence, and constant variance are met, a 99% confidence interval would be wider than the 95% interval. Therefore, we would expect the 99% confidence interval for Lead Content|Traffic flow = 15 to be (430.7, 629.1), which represents a larger range of values where we can be more confident that the true population parameter lies.

The total amount Marissa spent on both shirts and shorts is (19.99x + 14.99y) + 119.93.

The expression representing the total amount Marissa spent on shirts can be written as 19.99x. And the expression representing the total amount Marissa spent on shorts can be written as 14.99y. So, the expression representing the total amount Marissa spent on both shirts and shorts can be written as 19.99x + 14.99y.

The next day Marissa bought 3 more shirts and 4 more pairs of shorts. So, the expression representing the total amount Marissa spent on shirts would become 19.99x + 19.99 × 3 = 19.99x + 59.97. And the expression representing the total amount Marissa spent on shorts would become 14.99y + 14.99 × 4 = 14.99y + 59.96.

Therefore, the expression representing the total amount Marissa spent on both shirts and shorts can be written as 19.99x + 59.97 + 14.99y + 59.96 = (19.99x + 14.99y) + 119.93.

So, the total amount Marissa spent on both shirts and shorts is (19.99x + 14.99y) + 119.93.

Answer:

r = 9.61 cm

Step-by-step explanation:

Volume of a rectangular box = length × width × height

= 21.5 cm × 13.5 cm × 6 cm

= 1,741.5 cm³

Volume of a rectangular box = 1,741.5 cm³

Since,

Volume of a rectangular box = Volume of a circular box

Then,

1,741.5 cm³ = Volume of a circular box

Volume of a circular box = πr²h

1,741.5 cm³ = 3.14 * r² * 6 cm

1,741.5 = 18.84r²

r² = 1,741.5/18.84

r² = 92.436305732484

r = √92.436305732484

The stopping distance of D40 is 2.56 times the stopping distance of D25.

Given that are two initial velocities: 40 mph and 25 mph, with which the car's stopping distance is D40 and D25.

The final velocity for both is 0 mph (as the car to a stops).

We need to compare the stopping distance D40 to the stopping distance D25.

Use the third equation of motion for both cases to get the comparison.

The equation is given by:

\(v^2 - u^2 = 2as.\)

Case 1)

\(0 - 40^2 = 2a(D40)\)

Case 2)

\(0 - 25^2 = 2a(D25)\)

Comparing the obtained expressions.

\(\frac{40^2}{25^2} = \frac{2a(D40)}{2a(D25)}\)

\(2.56 = \frac{D40}{D25}\)

\(2.565 \times D25 = D40\)

Hence the stopping distance of D40 is 2.56 times the stopping distance of D25.

We can infer and logically deduce that airplane’s ground speed is equal to 658.94 kph.

Given the following data:

Speed can be defined as the distance covered by an object per unit of time. Thus, speed can be measured in kilometer per hour (kph).

Mathematically, speed can be calculated by using this formula;

Speed = distance/time

In order to calculate the airplane’s ground speed, we would apply the law of cosine:

C² = A² + D² - 2(A)(D)cosθ

Substituting the given parameters into the formula, we have;

C² = 700² + 60² - 2(700)(60)cos45

C² = 434,203.03

C = √434,203.03

C = 658.94 kph.

In conclusion, we can infer and logically deduce that airplane’s ground speed is equal to 658.94 kph.

In Mathematics and Geometry, the sum of the exterior angles of both a regular and irregular polygon is always equal to 360 degrees.

Note: The given geometric figure (regular polygon) represents a pentagon and it has 5 sides.

By substituting the given parameters, we have the following:

3x + 4x + 8 + 5x + 5 + 6x - 1 + 5x + 3 = 360°.

3x + 4x + 5x + 6x + 5x + 8 + 5 - 1 + 3 = 360°.

23x + 15 = 360°.

23x = 360 - 15
