Answer:

SA = 94 ft²

Step-by-step explanation:

To find the surface area of a rectangular prism, you can use the equation:

SA = 2 ( wl + hl + hw )

SA = surface area of rectangular prism

l = length

w = width

h = height

In the image, we are given the following information:

l = 4

w = 5

h = 3

Now, let's plug in the information given to us to solve for surface area:

SA = 2 ( wl + hl + hw)

SA = 2 ( 5(4) + 3(4) + 3(5) )

SA = 2 ( 20 + 12 + 15 )

SA = 2 ( 47 )

SA = 94 ft²

Answer: DE = 17

Step-by-step explanation:

You can solve by similar triangle ratios or by pythagorean theorem:

AB/CD = CD/x

54/76.5 = 12/x

Solve for x:  54x = 12(76.5) = 918

x = 918/54 = 17

Or, because CDE is a right triangle:

\(12^{2} + 12^{2} = x^{2}\)

\(x^{2} = 288\\\)

x = \(\sqrt{288} = 17\)

Answer:

C

Step-by-step explanation:

First we distribute (-2,3) into the equations so 2x+4y becomes 2(-2)+4(3) so that's -4+12 which is 8 making equation 1 correct.

Then x+2y becomes (-2)+2(3) which is 4 so the second equation is correct as well therefore the answer has to be C because of process of elimination

A. To save for her payout annuity with an ordinary annuity set up thirty years before her retirement, Holly Krech must make a monthly payment of $175.97.

B. If she sets up the ordinary annuity twenty years before her retirement, Holly Krech must make a monthly payment of $432.00.

To calculate the monthly payment for an ordinary annuity set up thirty years before retirement, we can use the formula for the present value of an ordinary annuity. Given the deposit amount of $218,437.048 and the total amount received from the annuity of $432,000, and solving for the monthly payment, we find that Holly must make a monthly payment of $175.97.

For an ordinary annuity set up twenty years before retirement, we use the same formula for present value. With the deposit amount and total amount received unchanged, we solve for the monthly payment, which comes out to be $432.00.

It's important to note that the monthly payment increases when the annuity is set up closer to the retirement date. This is due to the shorter time period available for saving, resulting in a higher required contribution to reach the desired payout amount.

Using the Pythagorean identity

sin²α + cos²α = 1 ( divide each term by sin²α )

\(\frac{sin^2\alpha }{sin^2\alpha }\) + \(\frac{cos^2\alpha }{sin^2\alpha }\) = \(\frac{1}{sin^2\alpha }\) , that is

The range of this relation include the following: f. {y ∣ -4 ≤ y ≤ 4}.

In Mathematics and Geometry, a range is the set of all real numbers that connects with the elements of a domain.

This ultimately implies that, a range simply refers to the set of all possible output numerical values (real numbers), which are shown on the y-coordinate (y-axis) of a graph.

Based on the information provided in this scenario, the domain and range of this relation in interval notation are as follows:

Domain = {-3, -2, 0, 3}

Range = {0, 4, -4, 2}.

Therefore, the range can be rewritten as {y ∣ -4 ≤ y ≤ 4}.

Absolute values are any digit's value without taking the sign into an account. Therefore, all negative numbers will be regarded as positive for absolute value. The absolute value of -5, for instance, will be 5, whereas that of -7, will be 7.

In essence, the absolute value calculates the distance from zero. Putting an absolute value on something does not imply that they are the same number but that they are the same distance from 0.

Given;

The triangle is a right angled triangle, whose one side is 26 and another side is X. It has also one angle that is 41°.

Now, taking reference angle as angle 41°. We get;

Perpendicular= 26

Base = X

and Reference angle = 41°.

We know that the ratio of tan is p/b. So, let's use this ratio.

\( \tan(41°) = \frac{26}{x} \)

\(0.869 \times x = 26\)

\(x = \frac{26}{0.869} \)

Therefore, The value of x is 29.90.

The German mark appreciated by 1.3% against the US dollar between 1970 and 1976.

This was due to strong economic growth in Germany and a decrease in inflation, which increased the purchasing power of the mark against the dollar. The appreciation of the mark against the dollar also helped to stimulate exports from Germany and reduce imports, creating a more balanced trade balance between the two countries.

The best definition for the term "period" is:

The horizontal distance required for the graph of a periodic function to complete one cycle.

In the context of periodic functions, the period represents the length of the interval over which the function repeats itself identically. It is the horizontal distance from any point on the graph to the corresponding point on the next complete cycle of the function.

The concept of a period is used to describe functions that exhibit regular and repetitive patterns.

To find A.), we must create a linear equation. Let b be the number of books Sam ordered. We write 5b because each book is 5 dollars. Then we add 4 dollars to the equation to represent the shipping fee. Then we write "equals to 89",  because it says that is the total cost. So we get the equation \(5b+\$4=\bold{\$89}\)

To find B.), we must solve the equation. Isolate the variable, by subtracting 4 from both sides. We then get \(5b=\$85\). Now we divide by 5 to get only the variable and to get rid of the coefficient. We get \(b=17\). So Sam bought 17 books.

Answer:

Diameter Length: ( About ) 5.4 km; Option B

Step-by-step explanation:

~ Let us apply the Area of the Circle formula πr^2, where r ⇒ radius of the circle ~

1. We are given that the area of the circle is 22.9 km^2, so let us substitute that value into the area of the circle formula, solving for r ( radius ) ⇒ 22.9 = π * r^2 ⇒ r^2 = 22.9/π ⇒ r^2 = 7.28929639361.... ⇒

radius = ( About ) 2.7

2. The diameter would thus be 2 times that of the radius by definition, and thus is: 2.7 * 2 ⇒ ( About ) 5.4 km

Diameter Length: ( About ) 5.4 km

The maximum distance that the plane can travel due west and just be able to return home is approximately ______ kilometers. (The actual value will be calculated in the explanation.)

To determine the maximum distance the plane can travel due west and return home, we need to consider the effect of the wind on the plane's ground speed. The ground speed is the speed of the plane relative to the ground.

Let's first convert the given speed of the plane to kilometers per hour:

Speed of the plane = 3.38 × 10^2 m/s

Speed of the plane in km/h = (3.38 × 10^2 m/s) × (3600 s/1 h) × (1 km/1000 m) = 1.2168 × 10^3 km/h

Next, we'll calculate the effective ground speed of the plane by considering the wind:

Effective ground speed = Speed of the plane - Speed of the wind

Effective ground speed = 1.2168 × 10^3 km/h - 67.3 km/h = 1.1495 × 10^3 km/h

Now, let's determine the maximum flight time based on the given fuel capacity:

Flight time = 7.3 hours

Finally, we can calculate the maximum distance the plane can travel due west:

Maximum distance = Effective ground speed × Flight time

Maximum distance = (1.1495 × 10^3 km/h) × (7.3 hours) = 8.38335 × 10^3 km

Therefore, the maximum distance that the plane can travel due west and just be able to return home is approximately 8.383 × 10^3 kilometers. (rounded to three significant figures)

True, a proportion is a type of ratio in which the numerator is part of the denominator and can be expressed as a percentage.

A proportion is a mathematical relationship between two numbers, showing that one number is a part of the other or that they share a certain ratio. It compares two ratios and checks if they are equal. For example, if we have two ratios 1:2 and 2:4, these ratios are in proportion because they have the same relationship (1 is half of 2, and 2 is half of 4).
To express a proportion as a percentage, follow these steps:
Convert the ratio to a fraction: In our example, the ratio 1:2 can be converted to the fraction 1/2.
Divide the numerator by the denominator: In this case, we will divide 1 by 2, which equals 0.5.
Multiply the result by 100: Finally, multiply 0.5 by 100 to get the percentage, which is 50%.
So, the statement is true that a proportion is a type of ratio in which the numerator is part of the denominator and can be expressed as a percentage. This concept is essential in various mathematical and real-life applications, such as calculating discounts, tax rates, and percentages of various quantities.

Given:

To find: weight of a 24 square foot, 2 inch thick aluminum plate

Finding:

By unitary method, we get:

Weight of 1 square foot aluminum plate = 15 lbs.

Weight of 24 square foot aluminum plate = 15(24) lbs = 360 lbs.

Again, by unitary method, we get:

Weight of 1 square foot, 1 inch thick aluminum plate = 15 lbs.

Weight of 24 square foot, 1 inch thick aluminum plate = 15(24) lbs = 360 lbs.

Weight of 24 square foot, 2 inch thick aluminum plate = 360(2) lbs = 720 lbs.
