They have dedicated an area that is equivalent to 900, 000 for farming Explain which unit of measurement-square inches, square ounces, or square feet-best describes these measurements. Be specific.
Answer: square feet
Step-by-step explanation:

225/100 * 1,000,000=
225*1,000,000/100=
225*10,000=2,250,000 ==> can't be square inches since a mile is 63,360 inches. This would mean that 2,250,000 is approximately 40 square miles which is small for a planet.
Square ounces is also a very small unit, so the only appropriate answer and the largest unit available is square feet.

Answer:
Mei is correct because -9 is to the left of -3 on the number line.
Step-by-step explanation:
This is because -9 is LESS than -3, when you add or subtract using negative numbers, such as 7-9, you get -2. However when you subtract 7-13, you get -6. Because you subtracted a greater number from 7, your answer is -6 is LESS than -2. This is the same with inequalities, greater negative numbers will always be smaller and smaller negative numbers will always be greater.

Yesterday, drove 44 and 1 half
miles. used 1 and 1 fourths
gallons of gasoline. What is the unit rate for miles per gallon?
Answer:
The unit rate for miles per gallons is 35.6 miles per gallon used by him.
Step-by-step explanation:
In the given condition he drove 44 and 1/2 miles and used a total of 1 and 1/4 gallons of gasoline.
Now, we have to calculate the number of miles he travelled in each gallon.
So, 44 and 1/2 miles can be written as 44.5 miles.
And 1-1/4 gallons can be written as 1.25 gallons.
Now, we need to form an equation from the above condition;
=> 44.5 = 1.25
=> x = 1 (here, x is the number of miles per gallon)
Now, after cross multiplying the equation;
=> 44.5 × 1 = 1.25 × x
=> 44.5 = 1.25 x
=> 44.5 / 1.25 = x
=> x = 35.6 miles per gallon
Therefore, the unit rate for miles per gallons is 35.6 miles per gallon used by him.

Write each equation in slope-intercept form. 1 Write the equation of the line perpendicular to yx that passes through the point (3,-8).
Answer:
The line perpendicular to YX that passes through the point (3,-8) is (y = − x + 5).
Step-by-step explanation:
It is given that a line perpendicular to YX passes through the point (3,-8).
Now,
The slope of the line perpendicular to the line YX is 1.
=> y = x
So, Slope = 1
Furthermore, the slope of the required line can be written as -1.
So, the required line can be written in slope-intercept form as;
=> y = − x + c
It is further given that the line passes through the point (3,2);
So, after putting all the value in the above-mentioned equation, we get;
=> 2 = − 3 + c
=> c = 5

Answer: 0.7
Step-by-step explanation:
Let the number of white cows be x
Thus, the number of brown cows be (x+12)
Hence,
x+(x+12)=60
x+x+12=60
2x+12=60
2x+12-12=60-12
2x=48
Divide both parts of the equation by 2:
x=24 white cows
x+12=36 brown cows
The number of white cows are less than one year old:

If the measure of arc CDE=118 degrees and the measure of arc EF=62 degrees calculate measure of angle FGE.
The measure of angle FGE from the given figure is 28° when the measure of arc CDE = 118° and the measure of arc EF = 62°.
How the measure of an arc and measure of an angle are related?The measure of an arc is equal to the measure of its corresponding central angle.
From the given figure, the measure of arc CDE = 118° = corresponding central angle (∠CAE)
So, ∠CAE = 118°
From the given figure, the measure of arc FE = 62° = corresponding central angle (∠FAE)
So, ∠FAE = 62°
As we know the radius of a circle is perpendicular to the tangent.
That is, AE ⊥ EG
So, ∠AEG = 90°
Now, ∠AGE+∠AEG+∠GAE = 180° (The sum of interior angles of a triangle is equal to 180°)
∠AGE + 90° + 62° = 180°
⇒ ∠AGE + 152° = 180°
⇒ ∠AGE = 28°
So, ∠AGE = ∠FGE = 28°

The table shows pricing information for two pizzas. How many toppings would
number 13 only
The number of toppings where the cost of each pizza would be equal is 5.
How many toppings would make the pizza equal?The first step is to formulate an equation that represents the cost of each type of pizza.
Total cost = price of cheese pizza + (price per topping x number of toppings)
Cost of pizza A = $10 + $1.50t
Cost of pizza B = $12.50 + t
When the cost of both pizzas are equal, the above equations would be equal to each other.
$10 + $1.50t = $12.50 + t
To determine the value of t, take the following steps:
Combine similar terms: 1.50t - t = $12.50 - $10
Add similar terms = 0.50t = 2,50

Use Fleury's Algorithm to find an Euler circuit through the graph by listing the vertices in the order visited.
Use Fleury's Algorithm to find an Euler path through the graph using this new edge by listing the vertices in the order visited is; G-H-L-K-G-J-I-G
How to find Euler's Path?A quick examination of the given graph tells us that two of the seven vertices (G, I) have an odd number of edges while the other five (F, H, J, K, L) have an even number. Since every vertex must have an even number of attached edges for us to possibly construct an Eulerian circuit, our first step is necessary to add an edge connecting G to I.
A somewhat easy way to now construct an Eulerian circuit would be to take our original graph (i.e. without the G-I edge) and find an Eulerian path from D to H, then end by taking our added D-H edge back to D.
The way to find Fleury's Algorithm, is that;
1) Start with classifying the vertices of the given graph as odd and even. If there are 0 or 2 odd vertices, then continue with the algorithm.
2) Begin with any one of the odd vertices, if they exist, otherwise arbitrarily choose a vertex as the starting point.
3) Travel every edge exactly once such that the bridges in the graph are travelled at the end.
4) Stop when all the edges are travelled.
