The spinner below shows 5 equally sized slices. Mal spun the dial 500 times and got the following results.

The solution to the system of inequalities 2x − y < 4 and x + y < −1 is the intersection of the shaded regions below the lines 2x - y = 4 and x + y = -1, labeled AB on the graph. Regions A and B represent the solutions to each individual inequality.

To solve the system of inequalities 2x − y < 4 and x + y < −1, we can use the following steps

Solve each inequality for y in terms of x

2x - 4 < y

-x - 1 < y

Plot the boundary lines for each inequality as dotted lines. To do this, we can use the equality signs instead of the inequality signs.

2x - 4 = y

-x - 1 = y

Shade the region that satisfies each inequality. To do this, we can test a point that is not on the boundary line in each inequality. For example, we can test (0,0) in the first inequality

2(0) - 0 < 4

0 < 4

Since (0,0) satisfies the first inequality, we shade the region below the line 2x - y = 4. Similarly, we can test (0,-2) in the second inequality

(0) + (-2) < -1

-2 < -1

Since (0,-2) satisfies the second inequality, we shade the region below the line x + y = -1.

The solution to the system of inequalities is the intersection of the shaded regions, which is labeled AB in the graph. The shaded region labeled AB is the region that satisfies both inequalities, which is the region below both lines.

The probability of a random point which is located on  AK  will be present on BE is equal to 0.3.

From the attached figure we have,

On the number line point A is located at -10.

And on the same number line point K is at 10.

Distance between AK = ( 10 ) - ( -10 )

⇒ Distance between AK = 10 + 10

⇒ Distance between AK = 20

Now, on the same number line location of point B is -8.

And location of point E is -2.

Length of BE = ( -2 ) - ( -8 )

⇒ Length of BE = -2 + 8

⇒ Length of BE = 6

Probability of random point on AK will be on BE

= Favorable outcomes / total number of outcomes

= Length of BE / Length of AK

= 6 / 20

= 3 / 10

= 0.3

Therefore, the probability of a random point located on AK will be on BE is equal to 0.3.

The surafce area of the cone with a slant height of 14 in and a diameter of 6 in is 160.2 in².

A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.

The surface area of a cone can be expressed as;

SA = πrl + πr²

Where r is radius of the base, l is the slant height of the cone and π is constant pi.

Given that:

Slant height l = 14 in

Diameter d = 6 in

Radius r = diameter/2 = 6/2 = 3in

S.A = ?

Plug the given values into the above formula and solve for the surface area.

SA = πrl + πr²

SA = ( π × 3in × 14in ) + ( π × (3in)² )

SA = 160.2 in²

Therefore, the surface area is 160.2 in².

The prism is a right hexagonal prism.

8)

Perimeter = 6 x side length = 6 x 12 cm = 72 cm

Each rectangular face of the prism has a height of 14 cm and a width equal to one of the sides of the hexagon, which is 12 cm.

The area of each face.

The exact value for the trigonometric function of numbers is derived to be √3/2.

Trigonometric identities are equations that involve the trigonometric functions (such as sine, cosine, tangent, cosecant, secant and cotangent) and are true for all possible values of the variables involved. These identities can be used to simplify trigonometric expressions, solve equations, and prove other mathematical statements.

Then sum and difference identities states that:

sin(A ± B) = sinAcosB ± cosAsinB

cos(A ± B) = cosAcosB ∓ sinAsinB

so;

sin(11°) cos(49°) + cos(11°) sin(49°) = sin(11 + 49)

sin(11°) cos(49°) + cos(11°) sin(49°) = sin(60°)

sin(11°) cos(49°) + cos(11°) sin(49°) = √3/2.

The fish tank requires 7900 square cm of glass.

First, choose three fish for our tank. Let's choose a neon tetra, a guppy, and a corydoras catfish.

According to the guideline given, each fish requires 4,000 cubic centimeters of water for every inch of a fish's length. Determine the total length of the three fish to calculate the required water volume.

Assuming the neon tetra is 1 inch long, the guppy is 2 inches long, and the corydoras catfish is 3 inches long, the total length of the fish is 1+2+3=6 inches.

To accommodate these three fish, we need 6 inches x 4,000 cubic centimeters of water per inch = 24,000 cubic centimeters of water.

To design the fish tank. Make it a rectangular prism shape with the dimensions of 50 cm x 30 cm x 40 cm (length x width x height).

To calculate the amount of glass necessary to build the tank, to find the surface area of the glass required. There are five sides to the tank (four sides and the base), find the area of each and add them up.

The front and back sides each have an area of 50 cm x 40 cm = 2000 square cm.

The two side walls each have an area of 30 cm x 40 cm = 1200 square cm.

The base has an area of 50 cm x 30 cm = 1500 square cm.

So, the total surface area of glass required is:

2(2000 square cm) + 2(1200 square cm) + 1500 square cm = 7900 square cm.

Therefore, 7900 square cm of glass is needed to build our fish tank.

Hello!

To find the equation of the line that passes through the points (0, -8) and (4, -3), we can use the point-slope form of the equation of a line, which is:

y - y1 = m(x - x1)

where (x1, y1) is a point on the line and m is the slope of the line.

First, we can find the slope of the line by using the formula:

m = (y2 - y1) / (x2 - x1)

where (x1, y1) = (0, -8) and (x2, y2) = (4, -3). Substituting these values, we get:

m = (-3 - (-8)) / (4 - 0) = 5/4

So the slope of the line is 5/4. Now we can use the point-slope form of the equation with either of the given points. Let's use the point (0, -8):

y - (-8) = 5/4(x - 0)

Simplifying this equation, we get:

y + 8 = 5/4x

Subtracting 8 from both sides, we get the final equation:

y = 5/4x - 8

So the equation of the line that passes through the points (0, -8) and (4, -3) is y = 5/4x - 8.

The resistance of 1800 feet of the same sort of wire with a 0.45in diameter is roughly 15037.45 ohms.

Let R be the resistance of the wire,

L be the length of the wire,

d be the diameter of the wire, and

k be a constant of variation.

Then we have the equation:

R = k * L / d^2

Solving for k to find the resistance of a wire of varying length and diameter.

We can create an equation using the information provided:

15611 = k * 700 / 0.2^2

Solving for k, we get:

k = 15611 * 0.2^2 / 700

k ≈ 0.1799

Using k to calculate the resistance of a wire with a length of 1800 feet and a diameter of 0.45 inches:

15037.45 ohms = 0.1799 * 1800 / 0.452 R

The result of the multiplication of the complex numbers z₁ and z₂ expressed in their polar form is -0.866 + 0.5i.

To multiply complex numbers expressed in polar form, we need to multiply their magnitudes and add their angles.

Let z₁ = r₁(cosθ₁ + isinθ₁) and z₂ = r₂(cosθ₂ + isinθ₂) be two complex numbers in polar form. Then their product is given by:

z₁*z₂ = r₁r₂(cosθ₁cosθ₂ - sinθ₁sinθ₂ + i(cosθ₁sinθ₂ + sinθ₁cosθ₂))

In this case, we have z₁ = 230° and z₂ = 540°. So, we need to convert these angles to radians and then find the cosine and sine values:

z₁ = 230° = 230/180 * π radians = 1.27 radians

z₂ = 540° = 540/180 * π radians = 3π radians

Now we can substitute these values in the formula above:

z₁z₂ = r₁r₂(cosθ₁cosθ₂ - sinθ₁sinθ₂ + i(cosθ₁sinθ₂ + sinθ₁cosθ₂))

= 1 * 1(cos1.27cos3π - sin1.27sin3π + i(cos1.27sin3π + sin1.27*cos3π))

We can see that the distance from the center of the wheel to the white plank is also 4 feet (since the radius of the wheel is 4 feet).

Next, we need to find the height of the white plank after the wheel is rolled forward through an angle of π/3 radians.

To do this, we can use trigonometry. Let's call the height of the white plank after the motion "h". We can use the sine function to relate the angle through which the wheel is rolled and the height of the plank:

sin(π/3) = h/4

Simplifying this equation, we get:

h = 4sin(π/3)

h = 4(√3/2)

h = 2√3

Therefore, the height of the white plank after the motion is 2√3 feet from the ground.

The requried 3 1/2 cups of chocolate chips would be needed for 7 dozen cookies, so the answer is (c).

The ratio of chocolate chips to cookies is 1 1/2 cups for every 3 dozen cookies. To find how much chocolate chips are needed for 7 dozen cookies, we can use the following proportion:

1 1/2 cups / 3 dozen cookies = x cups / 7 dozen cookies

where x is the unknown amount of chocolate chips needed for 7 dozen cookies.

To solve for x, we can cross-multiply and simplify:

(1 1/2 cups) * (7 dozen cookies) = (3 dozen cookies) * x
