Using angle relationships, the missing measures are:

m<3 = 138 degrees.

m<5 = 42 degrees.

m<8 = 138 degrees.

Using angle relationships, each of the measure of the angles can be calculated as follows:

Given that, m<1 = 138 degrees.

m<3 = m<1 [vertical angles are congruent]

Substitute:

m<3 = 138 degrees.

m<5 + m<3 = 180

Substitute:

m<5 + 138 = 180

m<5 = 180 - 138

m<5 = 42 degrees.

m<8 = m<3 [alternate interior angles are congruent]

m<8 = 138 degrees.

The closest answer choice is 0.76, which corresponds to 0.1934. So the answer is 0.1934.

We can calculate the variance of the hotel's star rating by using the formula:

variance = sum[(xi - mean)^2 * pi]

where xi is the rating (1, 2, 3, or 4), mean is the expected value of the rating, and pi is the proportion of the population that left that rating. Since we know the proportions of the population that left each rating, we can calculate the expected value of the rating as:

mean = 1(0.3) + 2(0.2) + 3(0.2) + 4(0.3) = 2.9

Then, we can calculate the variance as:

variance = (1 - 2.9)^2 * 0.3 + (2 - 2.9)^2 * 0.2 + (3 - 2.9)^2 * 0.2 + (4 - 2.9)^2 * 0.3

variance ≈ 0.57

Finally, the standard deviation is the square root of the variance:

standard deviation = sqrt(0.57) ≈ 0.756

Therefore, the closest answer choice is 0.76, which corresponds to 0.1934.

The total interest charges after 30 years with an APR of 3.4 % is given by the equation A = $ 77,550.80

The annual percentage yield (APY) is the real rate of return earned on an investment, taking into account the effect of compounding interest. An APR is a number that represents the total yearly cost of borrowing money, expressed as a percentage of the principal loan amount.

Given data ,

Let the total interest charges after 30 years be represented as A

Now , the equation will be

The APR percentage = 3.4 %

The amount taken as loan = $ 130,000

The number of years = 30 years

The monthly payment = $ 576.53

The number of payments n = 30 x 12 = 360 payments

So , the total amount paid in 30 years = monthly payment x number of payments

Substituting the values in the equation , we get

The total amount paid in 30 years = 360 x 576.53

The total amount paid in 30 years = $ 207,550.80

Now , the total interest charges after 30 years A = total amount paid in 30 years - amount taken as loan

Substituting the values in the equation , we get

The total interest charges after 30 years A = $ 207,550.80 - $ 130,000

On simplifying the equation , we get

Answer:

40 hours

26.09 hours

Step-by-step explanation:

What is the driving time for a ​1800-mile trip if you drive at an average speed of 45 miles per​ hour?

1800 / 45 = 40 hours

What is the driving time at 69 miles per​ hour?

1800 / 69 = 26.09 hours

Step-by-step explanation:

The driving time for a 1800-mile trip at an average speed of 45 miles per hour can be calculated as

Driving time = Total distance / Average speed

Driving time = 1800 miles / 45 miles per hour = 40 hours

Similarly, the driving time at an average speed of 69 miles per hour can be calculated as:

Driving time = 1800 miles / 69 miles per hour = 26 hours

So if you drive at an average speed of 45 miles per hour, the driving time for a 1800-mile trip would be 40 hours, and if you drive at an average speed of 69 miles per hour, the driving time would be 26 hours.

45 and 27.6 degrees are the two complementary angles.

When the right angle is split into two equal parts, each angle is 45°. A 45-degree angle is considered sharp. It is a right angle of half, or a 90-degree angle.

Angles that are complementary are those whose sum is 90 degrees. If the smaller angle has a measure of x, then the complementary angle's measure is 90 - x.

The issue shows that the greater angle (x + 17.4) is 17.4 degrees larger than the corresponding angle's measurement (90 - x). To find x, we can construct the following equation:

x + 17.4 = 90 - x + 17.4

When we simplify and find x, we obtain:

2x = 55.2

x = 27.6

The greater angle's measure is x + 17.4 = 45 degrees, while the smaller angle's measure is x = 27.6 degrees.

The two complementary angles are 27.6 and 45 degrees as a result.

The measure of angle ∠T found using the law of sines is about 72°

The law of sines states that the ratio of the of the sine of an angle in a triangle to the length of the opposite side, is the same for the three angles in a triangle.

Mathematically, where the side lengths of the triangle are; a, b, c, and the corresponding opposite angles are ∠A, ∠B, and ∠C, we get;

[tex]\frac{sin(A)}{a} = \frac{sin(B)}{b} = \frac{sin(C)}{c}[/tex]

The parameters in the question are;

AT = 28

AD = 37

m∠D = 46°

DT = a

Therefore, according to the law of sines, we get;

37/(sin∠T) = 28/(sin(46°))

Inverting both sides, we get;

(sin∠T)/37 = (sin(46°))/28

(sin∠T) = 37 × (sin(46°))/28

∠T = arcsine(37 × (sin(46°))/28) ≈ 72°

1,755 cm² icings are needed for one cake.

The correct option is (C).

What is the area of the circle?

The area of a circle is the amount of space enclosed within the circle. It is a measure of the size of the circle, and it is determined by the distance from the center of the circle to its edge (which is the radius). The formula for the area of a circle is:

A = πr²

The surface area of the circular top of the cake can be found using the formula for the area of a circle:

A = πr^2

where A is the area of the circle, and r is the radius. For the red velvet cake, the radius is 13 cm, so the area of the circular top of the cake is:

A = 3.14 x 13^2 = 530.66 cm^2 (rounded to two decimal places)

To find the surface area of the curved side of the cake, we need to find the circumference of the circular base and multiply it by the height of the cake. The circumference can be found using the formula:

C = 2πr

where C is the circumference and r is the radius. For the red velvet cake, the circumference of the circular base is:

C = 2 x 3.14 x 13 = 81.64 cm (rounded to two decimal places)

So, the surface area of the curved side of the cake is:

A = C x h = 81.64 x 15 = 1224.60 cm^2 (rounded to two decimal places)

Therefore, the total surface area of the cake that needs to be iced (excluding the circular bottom) is:

530.66 + 1224.60 = 1755.26 cm^2 (rounded to two decimal places)

Rounding to the nearest square centimeter, we get that approximately 1755 cm^2 of icing is needed for one red velvet cake at the Bisecting Bakery.

Therefore, 1,755 cm² icings are needed for one cake.

The correct option is (C).

You launch an object off a 55-foot cliff. If the object was launched at 85 feet/second,  64.23 feet/second long it will take for the object to hit the ground below. This can be solved using the concept of law of conservation of energy.

Three fundamental quantities all maintain their original values. Energy, momentum, and angular momentum are these. Energy is a conserved quantity, which could surprise you if you've read instances in previous pages, such the kinetic energy of charging elephants. The first law of thermodynamics, generally known as the law of conservation of energy, stipulates that the energy of a closed system must remain constant and cannot rise or fall on its own without external intervention.

Given that,

Height of the cliff, h= 55 Foot

Initial speed of the projectile, u = 85 m/s

Let, the projectile hit the ground with velocity "v"

Applying the law of conservation of energy,

mgh + 1/2 mu² = 1/2 mv²

or, m (gh + 1/2 u²) = 1/2 mv²

or, (gh + 1/2 u²) = 1/2 v²

or, 10 × 55 + (1/2 × (55)²) = 1/2 v²

or, 550 + 1512.5 = 1/2 v²
