Answer:

From the graph we can say that the number of page reads increase as the time increase, the slope of the line is a positive number as graph is increasing.

Step-by-step explanation:

Consider the provided graph.

The x axis represents the time spent reading one day.

The y axis represents the number of pages read.

From the graph we can observe as time is increasing the number of pages read is increasing.  

Although the rate is not constant.

Consider the figure 1:

The graph is strictly increasing from point A to B which shows that as time increase number of pages read also increase.

From point B to C the graph is a straight line that means from B to C as time increase the number of pages read remains the same or constant.

From point C to D the graph is again increasing which shows that as time increase number of pages read also increase.

Hence, from the graph we can say that the number of page reads increase as the time increase, the slope of the line is a positive number as graph is increasing.

Answer:

Step-by-step explanation:

Well, there are several  relationships you can describe.  As time increases how does number of pages  react?  Like does it increase or decrease.  Is it always increasing or decreasing by the same amount?  If it's not all the same how do different parts look different.  

There aren't any actual numbers, so you can't say specifically how they relate, like you can't say she read 5 pages a minute or something.

2. A drawing of a sailboat was made using a rectangle and two right triangles, as shown. What
Zarrin [17]

Answer:

  45 square centimeters

Step-by-step explanation:

The area of the triangle is given by ...

  A = (1/2)bh

where b is the base, 2 cm + 3 cm = 5 cm, and h is the height, 6 cm.

  A = (1/2)(5 cm)(6 cm) = 15 cm^2

__

The area of the rectangle is given by ...

  A = bh

where b is the base, 12 cm, and h is the height, 2.5 cm.

  A = (12 cm)(2.5 cm) = 30 cm^2

__

The area of the whole figure is the area of the triangle added to the area of the rectangle:

  drawing area = 15 cm^2 + 30 cm^2 = 45 cm^2

A trapezoid is 14 centimeters high and has bases that measure 13.5 centimeters and 27.5 centimeters. What is the area of the tra
Alexxandr [17]
Hello!

We can find the area of the trapezoid using the formula for area of a trapezoid:

FORMULA: 

A = [(b + b) * h / 2]

SUBSTITUTE: 

A = [(13.5 + 27.5) * 14 / 2]

SOLVE: 

A = 41 * 14 / 2

A = 574 / 2 

A = 287 cm²

So, the area of the trapezoid is 287 cm².

Find the length of the longest line segment that can be drawn on a rectangular board 3.07m by 2.24m
nikklg [1K]
For rectangle
l=3.07m
b=2.24m
so longest side that can be drawn is diagonal of rectangular board
=squareroot l^2+b^2
=squareroot3.07^2+2.24^2
=squareroot9.4249+5.0176
=squareroot14.4425
=3.80
So longest line that can be drawn in rectangular board is 3.80m

Circle A and circle B are congruent. CD is a chord of both circles. If AB = 8 ft and CD = 6 ft, how long is a radius?
bazaltina [42]

Let us say that the intersection point of lines AB and CD is called point E. The lines AB and CD are perpendicular to each other which also means that the triangle CEB is a right triangle.

Where the line CB is the radius of the circle while the side lengths are half of the whole line segment:

EB = 0.5 AB = 0.5 (8 ft) = 4 ft

CE = 0.5 CD = 0.5 (6 ft) = 3 ft

Now using the hypotenuse formula since the triangle is right triangle, we can find for the radius or line CB:

CB^2 = EB^2 + CE^2

CB^2 = (4 ft)^2 + (3 ft)^2

CB^2 = 16 ft^2 + 9 ft^2

CB^2 = 25 ft^2

<span>CB = 5 ft = radius</span>
