Arada [10]

Answer:

Below is the sample response

Step-by-step explanation:

The complementary event for choosing a red marble is choosing a blue or purple. The total number of marbles is 5. The probability of choosing a red marble is 1/5, and the complement would be 4/5. That is not the same as choosing a blue marble.

How do i find the value of a variable?

photoshop1234 [79]

To find the value of a variable you must know the basics of pre-Algebra.

Example:

2x+9=39

To find he answer of this you must subtract 9 from both sides

Then you are left with…

2x=30

Since 2x=30 means 2 times x equals 30

You can divide 2 from both sides to find the answer

Which is…

x=15

Jordan is cutting a 2 \text{ m}2 m2, start text, space, m, end text by 1\dfrac14\text{ m}1 4 1 m1, start fraction, 1, divided

sineoko [7]

Answer:

The area of each of the pieces is $\frac{5}{4} \ m.$

Step-by-step explanation:

The question is incomplete, so below is the complete question:

Jordan is cutting 2 meters by 1 \frac{1}{4} m piece of rectangular paper into 2 pieces along its diagonal.What is the area of each of the pieces?

Now, to get the area of each piece of paper.

So, the dimensions of piece of rectangular paper is 2 meters by $1\frac{1}{4}\ m.$

Now, to get the area of rectangular piece of paper:

$2\times 1\frac{1}{4}$

$=2\times \frac{5}{4}$

$=\frac{10}{4}\ m.$

The area of rectangular piece of paper = $\frac{10}{4} \ m.$

As, Jordan is cutting the piece of rectangular paper into 2 pieces along its diagonal.

Thus, the area of both the piece of paper are equal.

Now, to get the area of each piece of paper we divide the area of rectangular piece of paper by 2.

$\frac{10}{4} \div 2$

$=\frac{10}{4} \times \frac{1}{2}$

$=\frac{10}{8}$

On simplifying it:

$=\frac{5}{4}\ m.$

Therefore, the area of each of the pieces is $\frac{5}{4} \ m.$
