A plane takes off at an angle of elevation of 15° and travels in a straight line for 3,000 meters. What is the height of the plane above the ground at this instant?

Answer: 5%

Step-by-step explanation: In order to calculate the percentage of the discount we need to first calculate the amount of the discount.

$47.26 - $44.90 = $2.36 discount amount

In order to calculate the percentage of the discount you must divide the discount amount by the original cost.

$2.36 / $47.26 = .0499 = rounded off to a 5% discount

Answer:

The decrease is by 5%.

Answer:

The measure of the longer base is [tex]9\ cm[/tex]

The picture of the problem in the attached figure

Step-by-step explanation:

we know that

The area of a trapezoid is equal to

[tex]A=\frac{1}{2}(b1+b2)h[/tex]

where

b1 ----> the measure of the shorter base

b2 ----> the measure of the longer base

h ---> is the height

In this problem we have

[tex]A=30\ cm^{2}[/tex]

[tex]b1=6\ cm[/tex]

[tex]h=4\ cm[/tex]

substitute the values and solve for b2

[tex]30=\frac{1}{2}(6+b2)4[/tex]

[tex]15=(6+b2)[/tex]

[tex]b2=15-6=9\ cm[/tex]

The measure of the longer base is:

                            9 centimeters

We know that the area of a trapezoid with height h and two parallel bases b and b' is given by the formula:

[tex]\text{Area of trapezoid}=\dfrac{1}{2}\times (b+b')\times h[/tex]

Here we have:

The area of a trapezoid is 30 square centimeters. The height is 4 centimeters. The shorter base measures 6 centimeters.

i.e.  

[tex]30=\dfrac{1}{2}\times (b+6)\times 4\\\\30=2(b+6)\\\\b+6=\dfrac{30}{2}\\\\b+6=15\\\\b=15-6\\\\b=9\ \text{centimeters}[/tex]

Javier takes 5 1/8 minutes to jog 1 mile. Rashida can make 2 cupcakes with 1 cup of flour.

1a. To find out how many minutes it takes Javier to jog 1 mile, we can set up a proportion. Since he jogs 3/4 of a mile in 8 1/2 minutes, we can set up the equation: (3/4)/(8 1/2) = 1/x, where x is the number of minutes it takes him to jog 1 mile. To solve for x, we can cross multiply and simplify the equation.

First, we convert 8 1/2 to an improper fraction: 8 1/2 = 17/2.

Then, we can multiply both sides of the equation by 2 (to get rid of the denominator): (3/4) * 2 = (17/2) * (1/x). After simplifying, we get x = 5 1/8. Therefore, it takes Javier 5 1/8 minutes to jog 1 mile.

1b. To find out how many cupcakes Rashida can make with only 1 cup of flour, we can set up a proportion. Since the recipe calls for 1 2/3 cups of flour for 1 1/4 dozen of cupcakes, we can set up the equation: (1 2/3)/(1 1/4) = 1/x, where x is the number of cupcakes Rashida can make. To solve for x, we can cross multiply and simplify the equation.

First, we convert 1 2/3 to an improper fraction: 1 2/3 = 5/3.

Then, we can multiply both sides of the equation by 3 (to get rid of the denominator): (5/3) * 3 = (1 1/4) * (1/x). After simplifying, we get x = 2. Therefore, Rashida can make 2 cupcakes with 1 cup of flour.

Answer:

540g flour

4tsp baking powder

8tbsps sugar

520mL milk

4 eggs

8tbsps oil

Step-by-step explanation:

To find out how many times he would need to make the recipe, we can divide   20 by 5:

[tex]\frac{20}{5} =4[/tex]

Now we know that Sanjay must make the recipe four times to make 20 pancakes. We need to multiply each value by 4 to get how much he needs to make 20.

[tex](4)(135)=540\\(4)(1)=4\\(4)(2)=8\\(4)(130)=520\\(4)(1)=4\\(4)(2)=8[/tex]

Sanjay can make 20 pancakes by multiplying each ingredient in the original recipe for 5 pancakes by 4. This gives 540 g flour, 4 tsp baking powder, 8 tbsps sugar, 520 ml milk, 4 eggs, and 8 tbsps oil.

To adjust the quantities of ingredients for a recipe to make a different number of servings, we multiply the amounts of each ingredient by the factor that represents how many times the original number of servings we want to make. Sanjay's goal is to make 20 pancakes instead of 5, which is 4 times the original recipe. We'll multiply each ingredient quantity by 4 to find out how much of each is needed for 20 pancakes.

Multiply the amount of flour (135 g) by 4 to get 540 g of flour.

Multiply the amount of baking powder (1 tsp) by 4 to get 4 tsp of baking powder.

Multiply the amount of sugar (2 tbsps) by 4 to get 8 tbsps of sugar.

Multiply the amount of milk (130 ml) by 4 to get 520 ml of milk.

Multiply the amount of eggs (1 egg) by 4 to get 4 eggs.

Multiply the amount of oil (2 tbsps) by 4 to get 8 tbsps of oil.

Answer:

Total area = (8.2)(8.2) + 4[1/2(8.2) (10.3)]

Step-by-step explanation:

From figure we can see a square pyramid with base edge 8.2 and slant height 10.3

Points to remember

Total area of square pyramid = Base area + Lateral face area

Lateral face area = 4 * One face area

To find the lateral face area

The face is like a triangle with base 8.2 and slant height = 10.3

Area of triangle = bh/2

Face area = 1/2(8.2) (10.3)

Lateral surface area = 4[1/2(8.2) (10.3)]

To find the base are

Base is a square with base edge = 8.2

Base area = side * side = (8.2)(8.2)

To find the total area of pyramid

Total area = Base area + Lateral face area

Total area = (8.2)(8.2) + 4[1/2(8.2) (10.3)]

Therefore the correct answer is first option

2)Perpendicular Lines

3)Parallel lines

4)Circle

5)Angles

Final answer:

The five geometric terms—Plane, Perpendicular Lines, Parallel Lines, Circle, and Angle have been matched with their respective definitions using principles of Euclidean geometry.

Explanation:

Matching the geometric terms with their definitions will allow you to better understand the basic concepts of Euclidean geometry.

Plane: A flat surface that extends infinitely and has no depth; it has length and width.

Perpendicular Lines: Two lines that intersect at 90° angles.

Parallel Lines: Two lines that lie within the same plane and never intersect.

Circle: A set of all points in a plane that are a given distance from a point.

Angle: A figure consisting of two rays with a common endpoint.

Now you can match the terms to their definitions:

Plane - Definition 1

Perpendicular Lines - Definition 2

Parallel Lines - Definition 3

Circle - Definition 4

Angle - Definition 5

Answer:

x = (1/2)(ln 3)

Step-by-step explanation:

Please indicate exponentiation using the symbol " ^ ":

5e^(2x) - 4 = 11

To solve this, add 4 to both sides, obtaining:   5e^(2x) = 15

Next, divide both sides by 5, obtaining                e^(2x) = 3

Now take the natural logarithm (ln) of both sides:

2x = ln 3

Finally, divide both sides by 2, obtaining:           x = (1/2)(ln 3)

Answer:

5x = 100°

4x = 80°

Step-by-step explanation:

We are given a diagram with a straight line AC being intersected by another line BD and we are to find the two mentioned angles.

We know that the two angles (5x° and 4x°) are supplementary so their sum would be equal to 180°.

So we can write it as:

[tex]5x+4x=180[/tex]

[tex]9x=180[/tex]

[tex]x=\frac{180}{90}[/tex]

[tex]x=20[/tex]

Finding the measure of both the angles:

[tex]5x = 5(20) =[/tex] 100°

[tex]4x = 4(20) =[/tex] 80°

Answer:

<ABD = 100° and <CBD = 80°

Step-by-step explanation:

From the given figure we can see a linear pair

To find the value of x

The given two linear pair angles are,

1). 5x°

2) 4x°

The sum of linear pair angles is 180°

Therefore we can write,

5x + 4x = 180

9x = 180

x = 190/9 = 20°

To find two angles

<ABD = 5x = 5 * 20 =  100° and

<CBD = 4x = 4 * 20 = 80°

Therefore two angles are, <ABD = 100° and <CBD = 80°

Answer:

See below.

Step-by-step explanation:

Just like 18, continue with 19-21. Solve for x by rewriting each equation in log form.

[tex]e^x = 4.9\\\\x = ln 4.9\\\\x = 1.59[/tex]

When rewriting the form, the base of the exponent becomes the base of the log.

Here is your answer. x^5-3x^4+6x^2+x-9

The maximum height occurs at the vertex found using t = -b/2a

Solve for t

t = -20 / 2(-5) = -20/-10 = 2 seconds.

Now replace t with 2 in the original equation to solve for the height:

h(t) = -5t^2 + 20t + 110

h(2) = -5(2)^2 + 20(2) +110

h(2) = -5(4) + 40 + 110

h(2) = -20 + 40 + 110

h(2) = 130

Answer:

17.3 in

Step-by-step explanation:

(a) Diagonal on a face

First, we calculate the diagonal f on a face of the cube.

a² + a² = f²

       f² = 2a²

(b) Diagonal of the cube

Consider the triangle made by the diagonal d, diagonal f, and the edge of the cube

                                                            d² =  f²   + a²

Substitute the value of f²                   d² = 2a² + a² = 3a²

Take the square root of each side     d = a√3

Substitute the value of a                     d = 10√3 = 10 × 1.732 = 17.3 in

The diagonal of the cube is 17.3 in.

Answer:

251.33 or 251 1/3

Step-by-step explanation:

(-4, 7) would be the answer

A reflection of the point (4,7) over the line y=-x swaps and negates the x and y coordinates which leads to the new point being (-7,-4).

The image of the point (4,7) when reflected over the line y = -x is determined by essentially flipping the x and y coordinates of the original point and negating them.

This is because a reflection over the line y = -x swaps the x and y values and takes their opposite. Thus, the original point (4,7) would evolve into the point (-7,-4) after the reflection.

To break this down, the original x value was 4, and after reflection, this becomes -7 which is the new x-coordinate.

The original y value was 7, and after reflection, this becomes -4 which is the new y-coordinate. Therefore, the image of (4,7) after the reflection over the line y = -x is (-7,-4).
