Answer:

Length is 14

Width is 6

Step-by-step explanation:

Length = 2W + 2

Width = W

Perimeter is twice the length + twice the width

P = 40 = 2(2W+2) + 2W first simplify

40 = 4W + 4 + 2W  now combine terms

40 = 6W + 4 and subtract 4 from both sides

36 = 6W

Width W = 6

Length = 2W + 2 = 12 + 2 = 14

⇒ Supplementary angles are angles that add up to 180°

⇒ ∠1+∠2=180°(angles on a straight line)

∠2=∠4( Corresponding angles are equal m||n)

⇒*NOTE THE FOLLOWING STATEMENT IS TO MAKE YOU UNDERSTAND,IT MUST NOT BE INCLUDED IN YOUR ANSWERBOOK)

If ∠2=∠4

in the place of ∠2 in the equation ∠1+∠2=180° we can substitute ∠4 since the two angles (∠2 and ∠4) are equal by corresponding angles

______________________________________________________

⇒You may include this step now as you now know how ∠4 came up.

∴∠1+(∠4)=180°

∠1+∠4=180°

Now from the above equation we can see that ∠1 and ∠4 are supplementary angles as they both add up to 180°

.

Answer:

2a. 1/4

2b. 2/8

2c. yes, 1/4 = 2/8 because

2 / 8 = 2 ÷ 2 / 8 ÷ 2 = 1 / 4.

2d. the total number of parts doubled in the denominator, the number of parts represented in the numerator doubled as well.

The operations of division and multiplication are made proportionally to the numerator and denominator.

If x is his speed, and the speed limit is 65 mph, then the inequality \(x > 65\) represents him going over the speed limit.

The inequality \(x \le 65\) is when Jerry isn't over the speed limit (so he's going either 65 mph or slower than this).

Answer:

Total hectares needed = 13.3 billion hectares of ecological footprint.

Step-by-step explanation:

Country X's per capita ecological footprint = 3.2 hectares

Country Y's per capita ecological footprint = 0.6 hectares

Earth's population = 7 billion

Average footprint between the two nations = 1.9 (3.2 + 0.6) hectares

If everybody in the world (i.e. the earth's population) has an ecological footprint the size of the average footprint between these two countries, i.e. = 1.9 per capita of earth's population,

Therefore, the total hectares of ecological footprint needed will be equal to 7 billion x 1.9

= 13.3 billion hectares of ecological footprint.

The slope of this line is equal to -1/5.

An equation of the line in slope-intercept form that goes through the point (-5,-4) and is perpendicular to 5x - y = 1 is y = -x/5 - 2.

Mathematically, the standard form of the equation of a straight line is given by this mathematical expression;

y = mx + c

Where:

From the information provided, we have the following:

5x - y = 1. Therefore, the slope, m is equal to 5.

In Mathematics, a condition that must be met for two lines to be perpendicular is given by:

m₁ × m₂ = -1

5 × m₂ = -1

m₂ = -1/5

At point (-5, -1), an equation of this line can be calculated by using the point-slope form:

y - y₁ = m(x - x₁)

y - (-1) = -1/5(x - (-5))

y + 1 = -x/5 - 1

y = -x/5 - 1 - 1

y = -x/5 - 2

The image of the point L(-4,0) after a dilation with a center of (0,0) and a scale factor of 7 is the point L'(-28,0).

A dilation with a center of (0,0) and a scale factor of 7 means that every point in the plane will be multiplied by a factor of 7 from the origin.

To find the image of the point L(-4,0) after a dilation with a center of (0,0) and a scale factor of 7, we can simply multiply the coordinates of L by the scale factor.

The coordinates of the image point L' will be:

L' = (-4 × 7, 0 × 7) = (-28, 0)

Therefore, the image of the point L(-4,0) after a dilation with a center of (0,0) and a scale factor of 7 is the point L'(-28,0).

Answer:

Step-by-step explanation:

2 times the first and –1 time the second will eliminate the x variables in the equations.

Option E is the correct answer.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 9 is an equation.

We have,

(1/3)x - (2/3)y = 7 ____(1)

(2/3)x + 3y = 11 _____(2)

Now,

Multiply 2 on equation (1).

Multiply - 1 on equation (2).

We get,

(2/3)x - (4/3)y = 14

-(2/3)x  - 3y = -11    

           -(4/3)y - 3y = 14 - 11

Now x variable gets eliminated.

Thus,

2 times the first and –1 time the second will eliminate the x variables in the equations.

The builder will need a total of 372 square feet of countertop.

First, let's convert all dimensions to feet:

The 15' countertops are 15 * 12 = 180 inches long.

The 24" deep countertops are 24 / 12 = 2 feet deep.

The 48" x 36" island countertop is 48 / 12 = 4 feet wide and 36 / 12 = 3 feet deep.

Next, we can calculate the square footage of each countertop:

The 15' countertops are 180 inches long and 2 feet deep, so the square footage is 180 * 2 = 360 square feet.

The island countertop is 4 feet wide and 3 feet deep, so the square footage is 4 * 3 = 12 square feet.

Finally, we can add the square footage of each countertop to find the total square footage:

360 square feet + 12 square feet = 372 square feet

Therefore, The builder will need a total of 372 square feet of countertop.

2x-4 = g(x)

find f(2)-g(-1)

we substitute in function f(X) by value (2), and in function g(X) by value (-1)

1. 3^x +1 becomes 3^2+1 =9+1=10

the two planes will be at the same altitude of approximately 5675.48 feet after 49.45 seconds.

A plane is a flat two-dimensional surface that extends infinitely in all directions. In geometry, a plane is defined as a surface that is completely flat and has no thickness. It is often represented as a coordinate system with two perpendicular axes, usually labeled as the x-axis and y-axis.

Assuming that the two planes maintain their rates of ascent, we can use the following equations to determine when the planes will be at the same altitude:

altitude of plane A = 4000 + 33.5t

altitude of plane B = 3146 + 50.75t

where t represents time in seconds.

To find the time at which the two planes will be at the same altitude, we can set the two equations equal to each other and solve for t:

4000 + 33.5t = 3146 + 50.75tSubtracting 3146 from both sides, we get:

854 + 33.5t = 50.75t

Subtracting 33.5t from both sides, we get:

854 = 17.25t

Dividing both sides by 17.25, we get:

t = 49.45 seconds

Therefore, it will take approximately 49.45 seconds for the two planes to be at the same altitude. To find the altitude at which they will meet, we can substitute this value of t into either equation. Using the equation for plane A, we get:

altitude of plane A = 4000 + 33.5(49.45) = 5645.08 feet

Using the equation for plane B, we get:

altitude of plane B = 3146 + 50.75(49.45) = 5675.48 feet

Therefore, the length of the arc to the nearest 10th is 68.3 units.

In geometry, an arc is a portion of a curve that is part of the circumference of a circle, an ellipse, or another curved shape. An arc is defined by two endpoints and the curve between them, and it can be described by its length, central angle, or radius. The length of an arc is proportional to the size of the angle that it subtends at the center of the circle. Arcs are commonly used in trigonometry, calculus, and geometry to analyze and solve problems related to circles, angles, and curves.

Here,

The length of an arc is given by the formula:

length of arc = radius x angle in radians

In this case, the radius is 9.1 and the angle is 7.5 radians, so:

length of arc = 9.1 x 7.5

length of arc = 68.25
