The number of times that 3.08 × 10^8 is greater than 4.4 ×× 10^6 as a scientific notation is 0.7 × 10^2.

Scientific notation simply means the way of expressing numbers that are too big or too small.

In this case, the numbers that are given are 3.08 × 10^8 and 4.4 ×× 10^6

Then we have to divide them to know the number of times that it's greater. This will be:

= (3.08 × 10^8) / (4.4 × 10^6)

= 0.7 × 10^2

Using the given description < NOP is found to be 46 degrees

given data]

< OPQ = ( 9x - 19 ) degrees

< PNO = ( 2x + 5 ) degrees

< NOP = ( 3x + 16 ) degrees

From the figure described

let < NPO = y

< PNO + < NOP + y = 180 degrees ( sum of angles of triangle )

< OPQ + y = 180 degrees ( linear pair theorem )

Hence we equate both

< PNO + < NOP + y = < OPQ + y

< PNO + < NOP  = < OPQ + y - y

< PNO + < NOP  = < OPQ

( 2x + 5 ) + ( 3x + 16 ) =  ( 9x - 19 )

2x + 3x + 5 + 16 = 9x - 19

5x + 21 = 9x - 19

21 + 19 = 9x - 5x

The expression that is equivalent to [tex]\frac{5^{-10}}{5^{4}5^{0}}[/tex] is 1/5¹⁴

Expression:

An expression is a mathematical statement that does not contain an equal sign. It cannot be solved for unless the value of the variable is given.

Given,

Here we have the expression [tex]\frac{5^{-10}}{5^{4}5^{0}}[/tex]

Now we need to find the equivalent expression for this one.

In order to find the equivalent expression first we have to simplify the given expression.

For that we have to use the exponent rule,

1) Product of powers rule

When we multiplying two bases of the same value, keep the bases the same and then add the exponents together to get the solution.

2) Quotient of powers rule

When we dividing two bases with same value, keep the base the same, and then subtract the exponent values.

3) Negative exponent rule.

While we have the negative exponent then we have to convert them into fraction.

Based on the rule 1, we have simplify the denominator as,

[tex]\frac{5^{-10}}{5^{4}5^{0}}=\frac{5^{-10}}{5^{4+0}}\\\\= > \frac{5^{-10}}{5^{4}}[/tex]

Now we have to apply the rule (2), then we get,

=> 5⁻¹⁰⁻⁴

=> 5⁻¹⁴

Finally, we have to apply the thirds rule,

=> 1/5¹⁴

Therefore, the equivalent expression is  1/5¹⁴.

Answer: A 550g box for $10.89

Step-by-step explanation:

Represent each option as grams per dollar

225g / $5.77 = 38.99g / $1.00

550g / $10.89 = 50.51g / $1.00

725g / $16.89 = 42.92g / $1.00

The second option gives the most grams per dollar

The value of x when he equation given is solved is x = 4/27.

To solve for x in an equation, we have to apply all necessary properties of equality to will enable us isolate x to one side of the equation. The value of x is the solution to the equation that will make the equation a true statement.

Given the equation:

4(4/4x) + 5 = 32

Subtract 5 from both sides

4(4/4x) + 5 - 5 = 32 - 5 [subtraction property of equality]

4(4/4x) = 27

4/x = 27

Cross multiply

4 = 27(x)

4 = 27x

Divide both sides by 27 [division property of equality]

4/27 = 27x/27

4/27 = x

x = 4/27

If a student claims that 3.8¯ is an irrational number because it is a non-terminating decimal, then, he/she is incorrect as 3.8¯ can be represented as a fraction which is (35/9).

As per the question statement, a student claims that 3.8¯ is an irrational number because it is a non-terminating decimal.

We are required to determine if the claim is correct or incorrect, and if the claim is correct, then we will have to justify our answer, while if it is incorrect, we will have to determine the fraction that is equal to 3.8¯.

To solve this question, let us first try to convert our concerned decimal 3.8¯ into its equivalent fraction.

Now, 3.8¯ = 3.888...

Let us assume a random variable "x" such that, 3.8¯ = x = 3.888...

Then, 10x = (10 * 3.888...) = 38.888...

Now, [(10x - x) = {(38.888...) - (3.888...)}]

Or, (9x = 35)

Or, x = (35/9)

That is, the non-terminating decimal 3.8¯ can be converted to a fraction which is equal to (35/9).
Hence, the student's claim that that 3.8¯ is an irrational number because it is a non-terminating decimal is incorrect.

The answer is:

Jasmine ran 12 miles.

lilkyky67, this is the solution:

Let's recall that the angles in the image are consecutive interior angles and they add up to 180 degrees.

Therefore,

12x - 29 + 4x + 1 = 180

16x - 28 = 180

Adding 28 at both sides:

16x - 28 + 28 = 180 + 28

16x = 208

Dividing by 16 at both sides:

16x/16 = 208/16

x = 13

Now, we can find out the measures of the two angles, as follows:

First angle:

12x - 29 = 12 * 13 - 29

156 - 29 = 127

Second angle:

7.13 x 6 = 42.78

7 x 6 = 42

0.1 x 6 = 0.6

0.03 x 6 = 0.18

12 + 0.6 + 0.18 = 42.78
