Kira's time exercising every day can be represented as t  ≥ 40 because she exercises for 40 minutes or more.

<h3>How can this situation be represented?</h3>

This situation can be represented with an inequality. An inequality is an expression that is used to represent variables. This type of expression uses symbols such as >, < or ≥ to represent different variable values.

<h3>What inequality is represented in this situation?</h3>

  • The expression is: t ≥ 40

The inequality represented in this situation implies that Kira exercises is equal or more time than 40 minutes every day.

Astronomers measure large distances in light years. One light-year is the distance that light can travel in one year or approxim
Firlakuza [10]

Answer:

Option C =8.4672\times10^{13}

Step-by-step explanation:

Given : Astronomers measure large distances in light years. One light-year is the distance that light can travel in one year or approximately 5,880,000,000,000 miles.

Suppose a star is 14.4 light years from earth.

To find : How many miles away a star is from earth?

Solution :

In 1 light-year the distance a light can travel is = 5,880,000,000,000 miles.

                                                                   or = 5.88\times 10^{12} miles

In 14.4 lights year the distance is  =14.4\times (5.88\times10^{12})

                                                        =84.672\times10^{12}

                                                    or =8.4672\times10^{13}

Therefore, Option C is correct - =8.4672\times10^{13}

The sum of two numbers is nine. Using x to represent the larger of the two numbers, translate "the difference between one more t
Naddik [55]

Answer:

We have that the sum of two numbers  is 9

this can be written as:

x + y  = 9

where x is the larger number.

Now we want to write:

"the difference between one more than the larger number and twice the smaller number"

First, remember that the difference between A and B is:

A - B

Then "the difference between one more than the larger number and twice the smaller number"

is:

"one more than the larger number" = ( x + 1)

"twice the smaller number" = 2*y

the difference between these is:

(x + 1) - 2*y

Now we can simplify:

We know that:

x + y = 9

then:

y = 9 - x

replacing that in the equation:

(x + 1) - 2*y

we would get:

x + 1 - 2*(9 - x)

x + 1  -18 + 2x

(x + 2x) + (1 - 18)

3x - 17

This means that we can write:

"the difference between one more than the larger number and twice the smaller number"

as: 3x - 17
