Explanation:
The top and bottom lines are parallel as indicated by the same arrow markings on the lines.
Because they are parallel, this makes the angle x (see attached image) congruent to the 44 degree angle. They are alternate interior angles. So x = 44.
Using x = 44, we can find the angle y. Use the fact that all three angles of a triangle add to 180 degrees. We'll focus on the top triangle.
x+y+37 = 180
44+y+37 = 180 ... replace x with 44
y+44+37 = 180
y+81 = 180
y+81-81 = 180-81
y = 99
The last step we do is use this y value to find the value of n. Notice how the angle n and angle y combine to form a straight angle (aka straight line). So they add to 180 degrees
n+y = 180
n+99 = 180 ... replace y with 99
n+99-99 = 180-99
n = 81
which is the final answer
-----------------------------------------
Side Note: you can ignore the value of y if you want. Using the remote interior angle theorem, we add up the remote interior angles for the top triangle to get
x+37 = 44+37 = 81
which is the answer we got earlier.

How long does it take each horse to run a mile
Answers
The correct answer is;
Horse A will take 4 minutes to run 1 miles, while horse B will take 2 minutes 30 seconds to run 1 mile.
Analysing the graph, the Distance is measured in miles, while the Time is measured in minutes.
For horse A, the time taken to run 1 miles is 4 minutes, according to the graph.
For horse B, the time taken to run 1 mile is 2 minutes 30 seconds according to the graph.
Therefore, according to the graph, it will take horse A and horse B, 4 minutes and 2 minutes 30 seconds respectively, to run a mile.
Convert: y>3/2x-7/2 from point slope to standard form?
Answers
First multiply both sides of the inequality by 2 to clear out the fractions
y > (3/2)x - 7/2
2*y > 2*( (3/2)x - 7/2 )
2y > 2*( (3/2)x ) + 2*( -7/2 )
2y > 3x - 7
Now get the x and y terms to one side; move the 7 to its own side
2y > 3x - 7
2y+7 > 3x - 7+7 ... add 7 to both sides
2y+7 > 3x
2y+7-2y > 3x-2y ... subtract 2y from both sides
7 > 3x-2y
3x-2y < 7 ... flip the two sides and the inequality sign
We finally have the inequality into the form Ax+By < C where
A = 3
B = -2
C = 7
---------------------------------------------
The answer is 3x-2y < 7

Prove that triangle ABC must be isosceles
Answers
Then find <DCB: 180º - 90º - nº = 90-nº
Angle <ACB doesn't change: it is 90-n
but, <ABD is only part of <ABC: if we add <ABD with <DBC then we get 90-2n+n = 90-n
Definition of an isoceles triangle: It has two sides that are congruent or has two angles that are congruent.
Because both <ABC and <ACB equal 90-n the triangle ABC is an isoceles triangle.

Write 2036017 in expanded form using exponents
Answers
2 × 10 to the 6th power + 0 × 10 to the 5th power + 3 × 10 to the 4th power + 6 × 10 to the 3rd power + 0 × 10 to the 2nd power + 1 × 10 to the 1st power + 7 × 10 to the 0 power
The value of 2036017 in expanded form using exponent is expressed as (2 × 10⁶) + (3 × 10⁴) + ( 6 × 10³) + 10¹ + 7
Given the value 2036017, we are to express it in expanded form as shown:
2036017 = 2,000,000 + 30000 + 6000 + 10 + 7
Express each term as exponents
2,000,000 = 2 × 10⁶
30000 = 3 × 10⁴
6000 = 6 × 10³
10 = 10¹
Taking the sum of the exponents
2036017 = (2 × 10⁶) + (3 × 10⁴) + ( 6 × 10³) + 10¹ + 7
Hence the value of 2036017 in expanded form using exponent is expressed as (2 × 10⁶) + (3 × 10⁴) + ( 6 × 10³) + 10¹ + 7

angle P and angle Q are supplementary. If angle P = 2x and angle Q = x-3, find X
Answers
3x-3=180
3x=183
x=61
The angles P and Q are supplementary, meaning together they add up to 180 degrees. Based on the given expressions for these angles, solving for x yields x equals 61.
The given problem describes supplementary angles P and Q. Supplementary angles are two angles whose measures add up to 180 degrees. In this case, angle P is represented by 2x and angle Q is represented by x-3. The equation representing these supplementary angles is therefore 2x + (x - 3) = 180.
Combining similar terms, this equation simplifies to 3x - 3 = 180. To solve for x, add 3 to both sides obtaining 3x = 183. Finally, divide each side by 3 to find x = 61.

Walter is mixing cement for his new patio. He knows he needs to water-to-cement ratio of 20-30. What percent of his total mixture is water?
Answers
Divide the number of parts of water (20) over the total number of parts (50)
20/50 = 2/5 = 0.40
use a calculator or long division to find the decimal form of 2/5 to be 0.40
Then move the decimal point 2 spots to the right to go from 0.40 to 40%
Answer: the percent of water in the mix is 40%
Final answer:
To find the percentage of water in Walter's mixture with a water-to-cement ratio of 20-30, the water part is 20 out of 50 total parts, which equates to 40% of the mixture being water.
Explanation:
Walter needs a water-to-cement ratio of 20-30 for his patio cement mixture. To find out what percent of his total mixture is water, we can interpret the ratio as a fraction and then convert that fraction to a percentage. The fraction for water is 20 parts out of a total of 20 (water) + 30 (cement) parts, which is 20/50. To convert this to a percentage, we multiply by 100%.
Calculating the percentage: (20/50) × 100% = 40%
Therefore, 40% of Walter's total mixture is water.
