Lisa wanted to study how the area of a rectangle changes with the length if it’s width is fixed. She computed the areas of several rectangles that have the same width and different lengths. She then employed the results and connected them with a line, as shown in the picture. The graph shows the area (in m2) versus the length (in m)

b. Range

(Sorry I keep asking so many questions it’s because these questions are questions of things I have NEVER learned at all yet and it is a new module. When people explain and show me the work I write them in my book with the explanations as well when people put them down and that is how I start to learn this ahead of time.)

Answer:

Johnny is wrong.

Step-by-step explanation:

To compare two quantities, they must both be written in the same units. In this case, both must be in centimeters or millimeters. So, we must convert 600cm to millimeters or vice versa.

If we choose to use milimeters, we have

600cm=600cm [tex]\frac{10mm}{1cm}[/tex]

600cm = (600)(10) mm

600cm = 6000 mm

Now, we must compare 6000 mm with 5642 mm. We can see that 6000mm is greater than 5642 mm. hence, it is enough moulding for the baseboards.

In fact, 6000-5642 mm =358 mm would remain.

Answer:

2x - 10 = 34 degrees

3x - 10 = 56 degrees

Step-by-step explanation:

Since they're complementary, they'd equal 90-degrees.

Solve for x:

2x - 10 + 3x - 10 = 90

5x -20 = 90

5x = 110

x = 22

2(22)-10 = 34

3(22)-10 = 56

Answer:

Tan J = 0.2917

Step-by-step explanation:

Here, we want to find the value of tan J

Firstly, we need to understand that the numbers 24, 25 and 7 are a Pythagorean triple and as such the three measures represent the values of length of the sides of a right angled triangle

The tangent of an angle= measure of the opposite/measure of the adjacent

In the question, the opposite to point J measures 7 while the adjacent measures 24

So ;

tan J = 7/24

= 0.2917

Answer:

110.5 cm²

Step-by-step explanation:

The figure is composed of a rectangle with a triangle on top.

Area of rectangle = 13 × 6 = 78 cm²

Area of triangle = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here b = 13 and h = 11 - 6 = 5 cm , then

A = [tex]\frac{1}{2}[/tex] × 13 × 5 = 32.5 cm°

Thus

total area = 78 + 32.5 = 110.5 cm²

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

We know that line CD passes through the two points (0, 2) and (4, 6).

First and foremost, let’s find the slope of the line. We can use the slope formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where (x₁, y₁) and (x₂, y₂) are our two points.

So, let’s let (0, 2) be (x₁, y₁) and (4, 6) be (x₂, y₂). Substitute appropriately:

[tex]\displaystyle m=\frac{6-2}{4-0}[/tex]

Evaluate:

[tex]\displaystyle m=\frac{4}{4}=1[/tex]

Hence, our slope is 1.

Now, we can use the slope-intercept form:

[tex]\displaystyle y=mx+b[/tex]

Where m is our slope and b is our y-intercept.

Notice from our given points that we are given (0, 2).

So, our y-intercept is 2.

Therefore, we will substitute 1 for m and 2 for b. This yields:

[tex]\displaystyle y=(1)x+(2)[/tex]

Simplify:

[tex]\displaystyle y=x+2[/tex]

Hence, our answer is C.

B

Answer:

y = [tex]\frac{1}{3}[/tex] x - 1

Step-by-step explanation:

x - 3y = 6 ⇔ y = [tex]\frac{1}{3}[/tex] x - 2

y = [tex]\frac{1}{3}[/tex] x - 1

Answer:

23000

Step-by-step explanation:

If you multiply 20,000 * 0.05 (the percentage of the rate) you get 1000

This means that for 3 years he will pay an interest of 3000, plus the original loan 20000 which means he will pay 23000 :D

Step-by-step explanation:

yes it does matter the The x-coordinate always comes first, followed by the y-coordinate.

Answer:To locate (2,5), move 2 units to the right on the x-axis and 5 units up on the y-axis. The order in which you write x- and y-coordinates in an ordered pair is very important. The x-coordinate always comes first, followed by the y-coordinate.

[tex]y \ge 2x +4[/tex]

Start by analyzing each inequality

The inequality sign in [tex]x + 3y > 6[/tex] means that:

Answer:

The slope is 5/12

Step-by-step explanation:

To find the slope between any two points, we can use the slope formula:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Where (x₁, y₁) and (x₂, y₂) are our two points.

We have the two points (-9, 1) and (3, 6).

Let’s let (-9, 1) be (x₁, y₁) and let (3, 6) be (x₂, y₂). Substitute appropriately:

[tex]\displaystyle m=\frac{6-1}{3-(-9)}[/tex]

Evaluate:

[tex]\displaystyle m=\frac{5}{12}[/tex]

So, the slope of the line that contains the two points (-9, 1) and (3, 6) is 5/12.
