Answer:

Miles, missing number: 13

Hours, missing number: 1/25 ?

The missing values are 3 and 2/3

A ratio indicates the number of times one number contains another.

Let the missing number in the "miles" row be x and the missing number in the hour's row be y.

Since the values are equivalent ratios, it follows:

18/(4/5) = x/(2/15)

90/4 = 15x/2

15x = 45

x = 3

Similarly,

3/(2/15) = 15/y

45/2 = 15/y

y = 30/45

y = 2/3

The ratios of the missing columns are:

3 : 2/15 and 15 : 2/3

Hence, the missing values are 3 and 2/3.

Step-by-step explanation:

Since the girls have the same age, let their age be x.
Then, their average is

\(\frac{x+x}{2} = \frac{2x}{2} = x\)

Let \(S_{i}\) denote the age of 'i' girls.
Then, \(S_{8} = S_{6} + x + x - eq(1)\)

Also, we have,

\(\frac{S_{8}}{8} =15 - eq(2)\)

\(\frac{S_{6}}{6} =13 - eq(3)\)

Then eq(2):

(from eq(1) and eq(3))

\(\frac{S_{6} + 2x}{8} =15\\\\\frac{13*6 + 2x}{8} = 15\\\\78+2x = 120\\\\2x = 120-78\\\\x = 21\)

The average of the other two girls with equal age​ is 21

To find the consumer's and producer's surplus, we need more information about the demand and supply functions or the market equilibrium.

You provided the demand function D(x) = 25, but we require additional details to proceed with the calculations. The consumer's surplus is the difference between the maximum price consumers are willing to pay and the price they actually pay. It represents the benefit or surplus gained by consumers in a market transaction.

The producer's surplus is the difference between the minimum price producers are willing to accept and the price they actually receive. It represents the benefit or surplus gained by producers in a market transaction.

To calculate these surpluses, we typically need information about the supply function, equilibrium price, and equilibrium quantity. These values help determine the areas of the consumer's and producer's surpluses on the supply-demand graph.

For the 0.5 mm thickness, the two principal stresses are 66.5 MPa (tension) and 0 MPa (compression), and the maximum shear stress is 33.25 MPa. For the 5 mm thickness, the two principal stresses are 3.5 MPa (tension) and 0 MPa (compression), and the maximum shear stress is 1.75 MPa.

To solve this problem, we can use the formula for the hoop stress in a thin-walled cylinder:
Hoop stress = (pressure x radius) / thickness

(i) For the 0.5 mm thickness:
Radius = (10 mm - 0.5 mm) / 2

= 4.75 mm

Hoop stress = (7 MPa x 4.75 mm) / 0.5 mm

= 66.5 MPa

To find the principal stresses, we can use the following formula:
Principal stress = \(\frac{(\text{hoop stress} + \text{axial stress}) }{2} \pm \sqrt{((\text{hoop stress} - \text{axial stress}) / 2)^2 + \text{shear stress}^2}\)

Since the tube is thin-walled, we can assume that the axial stress is negligible.

Therefore.
Principal stress = \(\frac{(66.5 \ MPa + 0 \ MPa) }{2} \pm \sqrt{((66.5 \ MPa - 0 \ MPa) / 2)^2 + 0^2 \ MPa}\)
Principal stress = 33.25 MPa ± 33.25 MPa
The two principal stresses are 66.5 MPa (tension) and 0 MPa (compression).

The maximum shear stress is equal to half the difference between the two principal stresses, i.e. 33.25 MPa.

(ii) For the 5 mm thickness:

Radius = (10 mm - 5 mm) / 2

= 2.5 mm

Hoop stress = (7 MPa x 2.5 mm) / 5 mm

= 3.5 MPa

Principal stress = \(\frac{(3.5 \ MPa + 0 \ MPa) }{2} \pm \sqrt{((3.5 \ MPa - 0 \ MPa) / 2)^2 + 0^2 \ MPa}\)
Principal stress = 1.75 MPa ± 1.75 MPa
The two principal stresses are 3.5 MPa (tension) and 0 MPa (compression).
The maximum shear stress is equal to half the difference between the two principal stresses, i.e. 1.75 MPa.

The diameter of the circle is approximately 60 inches.

To explain further, we can use the formula relating the central angle of a sector to the length of its intercepted arc. The formula states that the length of the intercepted arc (A) is equal to the radius (r) multiplied by the central angle (θ) in radians.

In this case, we are given the central angle (225 degrees) and the length of the intercepted arc (30π inches).

To find the diameter (d) of the circle, we need to find the radius (r) first. Since the length of the intercepted arc is equal to the radius multiplied by the central angle, we can set up the equation 30π = r * (225π/180). Simplifying this equation gives us r = 20 inches.

The diameter of the circle is twice the radius, so the diameter is equal to 2 * 20 inches, which is 40 inches. Therefore, the diameter of the circle is approximately 60 inches.

In summary, by using the formula for the relationship between central angle and intercepted arc length, we can determine the radius of the circle. Doubling the radius gives us the diameter, which is approximately 60 inches.

Equation of the tangent line to the curve  \(xe^{y} + ye^{x} = 5\) at5 the point (0,5) is y = - (\(e^{5}\) + 5)x + 5.

Given curve is,

\(xe^{y} + ye^{x} = 5\)

We will differentiate both sides with respect to x,

\(\frac{d}{dx}\)\([xe^{y} + ye^{x} ]\) = \(e^{y} + xe^{y}\frac{dy}{dx} + e^{x}\frac{dy}{dx} + ye^{x}\) = 0

⇒ \(\frac{dy}{dx}\) \([xe^{y} + e^{x} ] = - [e^{y} + ye^{x} ]\)

⇒ \(\frac{dy}{dx}\) = \(- \frac{e^{y}+ye^{x} }{xe^{y}+e^{x} }\)

We have to find the equation at point (0,5).

Therefore substituting values of x and y,

that is x = 0 and y = 5.

\(\frac{dy}{dx} = - \frac{e^{5}+(5)e^{0} }{(0)e^{5} + e^{0} }\)

    = \(- \frac{e^{5} + 5}{1}\)

\(\frac{dy}{dx}\)  = - [\(e^{5}\) + 5] = gradient

Therefore the equation of tangent line is

(y - y1) = [m(x - x1)]

where m is the gradient

⇒ y - 5 = - [(\(e^{5}\)+5)(x - 0)]

The converse of the statement "If a figure is a square, its diagonals divide it into isosceles triangles" would be:

"If a figure's diagonals divide it into isosceles triangles, then the figure is a square."

The converse statement is not necessarily true. While it is true that in a square, the diagonals divide it into isosceles triangles, the converse does not hold. There are other shapes, such as rectangles and rhombuses, whose diagonals also divide them into isosceles triangles, but they are not squares. Therefore, the converse of the statement is not always true.

Therefore, the converse of the given statement is not true. The existence of diagonals dividing a figure into isosceles triangles does not guarantee that the figure is a square. It is possible for other shapes to exhibit this property as well.

In conclusion, the converse statement does not hold for all figures. It is important to note that the converse of a true statement is not always true, and separate analysis is required to determine the validity of the converse in specific cases.

To calculate the energy of the resulting explosion when a 10,000 kg UFO made of antimatter crashes with a 40,000 kg plane made of matter, we can use Einstein's famous equation, E=mc², which relates energy (E) to mass (m) and the speed of light (c).

In this case, we'll need to calculate the total mass of matter and antimatter involved in the collision and then use the equation to find the energy released. The equation E=mc² states that energy is equal to the mass multiplied by the square of the speed of light (c). In this scenario, we have a collision between a UFO made of antimatter and a plane made of matter. Antimatter and matter annihilate each other when they come into contact, resulting in a release of energy.

To calculate the energy of the resulting explosion, we need to determine the total mass involved in the collision. The total mass can be calculated by adding the masses of the UFO and the plane together. In this case, the UFO has a mass of 10,000 kg and the plane has a mass of 40,000 kg, so the total mass is 50,000 kg.

Next, we can use the equation E=mc² to calculate the energy. The speed of light (c) is a constant value, approximately 3 x 10^8 meters per second. Plugging in the values, we have E = (50,000 kg) x (3 x 10^8 m/s)². Simplifying the equation, we have E = 50,000 kg x 9 x 10^16 m²/s².Multiplying the numbers, we get E = 4.5 x 10^21 joules. Therefore, the energy of the resulting explosion when the UFO and plane collide is approximately 4.5 x 10^21 joules.

Answer: y > x + 4

Step-by-step explanation:

First lets find a linear equation for the dividing line, in the form:

y = mx + b

We know that b is 4, since this is the y-intercept

lets use any point on the graph, I'll use (-4, 0):

y = mx + 4

0 = m(-4) + 4

-4 = -4m

m = 1

So the slope is 1. Our completed formula for the line is:

y = x + 4

Since the left side of this graph is shaded, we know it will either be > or ≥. Since the line is also dotted we know it is denoted by a simple ">" sign.

So our completed inequality equation is: y > x + 4

Hope this helped!

Answer:

\(\sf y > x+4\)

Step-by-step explanation:

Choose 2 points on the line:  (-4, 0) and (0, 4)

\(\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{4-0}{0-(-4)}=1\)

point-slope form of linear equation:  \(\sf y-y_1=m(x-x_1)\)

\(\implies \sf y-0=1(x-(-4))\)

\(\implies \sf y=x+4\)

Solid line : ≤ or ≥

Dashed line: < or >

Therefore as the line is dashed, and the shading is above the line,

\(\implies \sf y > x+4\)
