Answer:

Both are correct.

A) A decimal fraction

B) A common fraction

Step-by-step explanation:

<u>1 step.</u> Write down 0.4 divided by 1:

\dfrac{0.4}{1}.

<u>2 step.</u> Multiply both top and bottom by 10 (because there are 1 digit after the decimal point):

\dfrac{0.4}{1}=\dfrac{0.4\cdot 10}{1\cdot 10}=\dfrac{4}{10}.

This fraction is called a decimal fraction.

<u>3 step.</u> Simplify the decimal fraction:

\dfrac{4}{10}=\dfrac{2\cdot 2}{2\cdot 5}=\dfrac{2}{5}.

This fraction is called a common fraction.

A rectangular piece of stained glass has the dimensions shown in the diagram. What is the probability that a random leaf that la
weeeeeb [17]

Answer:

The correct option is D) \frac{2}{3}

Step-by-step explanation:

Consider the provided figure.  

We need to find the probability that a random leaf that lands on the rectangle lands within the section shaped like a trapezoid.

For this first find the total area as shown:

The given figure is a rectangle.

The area of rectangle is l\times b

Where, l = 6 cm + 3 cm = 9 cm and b = 5cm

Therefore the area of the rectangle is;

Area of rectangle = 9cm\times 5cm=45cm

Now find the area of trapezoid.

The area of trapezoid is: \frac{a+b}{2}h

Where h is the height and a and b are the parallel sides.

Area of trapezoid = \frac{9+3}{2}\times 5=30

Thus, the area of trapezoid is 30 cm.

Therefore, the probability that a random leaf that lands on the rectangle lands within the section shaped like a trapezoid is:

Probability=\frac{\text{Area of trapezoid}}{\text{Area of rectangle}}

Probability=\frac{30}{45}=\frac{2}{3}

Hence, the correct option is D) \frac{2}{3}

Calculate the rise and run and find the slope ( -1,3) and (-2,7)
Serggg [28]
Howdy! :D

Slope formula:

m= (y2-y1)/(x2-x1)

m= (7-3)/(-2-(-1)

m=4/(-2+1)

m=4/-1

The rise is 4. The run is -1. The slope is -4.

I hope this helps!
