The scientific notation for the mass of 49,000 molecules of oxygen is 4.9 × 10⁴ grams.

To transform numbers into scientific notation, use the following rule: In scientific notation, the exponent equals the number of times the decimal point must always be shifted to produce a number between 1 and 10.

For the given value;

= 49,000 grams

write the number such that only one digit is left to the left of decimal of the number and the remaining digits to the write are written to the power of 10

= 4.9000 × 10⁴

This could be written as;

= 4.9 × 10⁴.

Therefore, the value of the mass of 49,000 oxygen molecules in the form of scientific notation is 4.9 × 10⁴ grams.

The value of e is 33/5 or 6.6 era.

It is given in the question that:-

e*i = 9r

Where,

e represents era

i represents the number of innings pitched, and

r represents the number of earned runs allowed

Also, we are given that:-

i = 45 innings, and

r = 33 earned runs allowed

We have to find the value of e for the given data.

Hence, applying the formula given in the question, we get

e*45 = 9*33

Now, as only one variable is left in the equation, it has become a linear equation in one variable.

Hence, solving the linear equation, we get

e = (9*33)/45

e = 33/5

Hello!

Solve for x by isolating the variable.

The value of x is 20.

Applying the linear pair postulate, m<SQR = 74°.

According to the linear pair postulate, the equation below is holds true:

m<TQS + m<SQR = 180.

m<TQS = (3m + 1)°

m<SQR = (2m + 4)°

Substitute the values

(3m + 1) + (2m + 4) = 180

Solve for m

3m + 1 + 2m + 4 = 180

Add like terms

3m + 2m + 1 + 4 = 180

5m + 5 = 180

Subtract 5 from both sides of the equation

5m + 5 - 5 = 180 - 5

5m = 175

m = 35

m<SQR = (2m + 4)° = 2(35) + 4 = 74°.

The distributive property of multiplication over addition is A (B + C) = AB + AC.

Properties of Numbers.

Numbers are have 5 main properties of operation which are:

Given,

Here we have to write the distributive property of multiplication over addition of a conditional statement.

Basically, the distributive property defines the distributing ability of operation over another mathematical operation within a bracket.

It can be either distributive property of multiplication over addition or distributive property of multiplication over subtraction.

Here we need to write the distributive property of multiplication over addition of a conditional statement.

So, The distributive property of multiplication over addition is expressed as

=> A × (B + C) = AB + AC.

Let us verify this property with the help of an example.

For example:

The expression 2(1 + 4) using the distributive law of multiplication over addition.

=> 2(1 + 4) = (2 × 1) + (2 × 4)

⇒ 2 + 8 = 10

Hence, the distributive property of multiplication over addition is stated.

The reflection transformation of the given diagram means that; W' X' is parallel to Z' Y'

Reflection over y-axis is a reflection or flip over the y-axis where the y-axis is the line of reflection used. The formula for this is: (x,y) →(−x,y) ( x , y ) → ( − x , y ) .

To reflect an equation over the y-axis, simply multiply the input variable by -1: y=f(x)→y=f(−x) y = f ( x ) → y = f ( − x )

Thus, looking at the given image and applying the transformation rule above, we can say that the reflection of parallelogram WXYZ across the y-axis would mean that W' X' is parallel to Z' Y'
