HELP MEEE!! Please evaluating a compound. Inequality using a graph

Mathematics
1 answer:
Irina-Kira [14]3 years ago
6 0

Answer:

\frac{x}{2}

Step-by-step explanation:

From the graph, we can conclude that,

x is less than 2 and not including as there is a hollow circle at the mark 2.

Also, x is greater than or equal to 7 including 7 as there is a solid circle at the mark 7

So, the compound inequality will be x

Now, the option that simplifies to the above inequality is the required answer.

Let us check the first option.

\frac{x}{2}

\frac{x}{2}

Therefore, option 1 simplifies to the above compound inequality.

So, the correct answer is option 1.

victus00 [196]

Answer:

d) 105.7\ \text{gallons}

Step-by-step explanation:

150\ \text{miles} requires 45.3\ \text{gallons of fuel}

1\ \text{mile} requires \dfrac{45.3}{150}\ \text{gallons of fuel}

200\ \text{miles} requires 200\times \dfrac{45.3}{150}=60.4\ \text{gallons of fuel}

So, total amount of gasoline required for the trip is 60.4+45.3=105.7\ \text{gallons}.

Bad White [126]

Answer:

D

Step-by-step explanation:

Labor productivity is is measured per hours.

Hence, the work he does [amount of claims] will be distributed amongst the amount of hours he works. The amount of dollar he uses <em>doesn't matter for labor productivity.</em>

<em />

Thus, his work is 6 claims. He does that is 8 hours. So claim/hr is:

6/8 = 0.75 claims per hour

Answer choice D is right.

lions [1.4K]
<h2>Answer:</h2>

Option: B is the correct answer.

                    B. 36,623 feet

<h2>Step-by-step explanation:</h2>

The angle of elevation is: 55 degree

We model this problem by taking a right angled triangle such that the side opposite to the 55 degree is of length 30000 feet.

Now let us consider x denote the distance of the plane from Francesa.

i.e. x denote the hypotenuse of the right angled triangle.

Hence, in right angled triangle i.e. ΔABC we have:

\sin 55=\dfrac{30000}{x}\\\\i.e.\\\\x=\dfrac{30000}{\sin 55}\\\\i.e.\\\\x=\dfrac{30000}{0.81915}\\\\\\i.e.\\\\\\x=36623.2376\ feet

Round to the nearest feet we get: x=36,623 feet
