A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.
In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠m + m∠n + m∠o = 180 degrees (sum of angles in a triangle)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step 2; m∠p − m∠o = 90 degrees (alternate interior angles)

Juan and Gloria are comparing the two numbers 354.6 and 354.06. Juan says that 354.06 is equal to 10 x 354.6. Gloria says he is wrong. Do you agree with Juan or Gloria? Explain your thinking.
Juan is incorrect; Gloria is right. 354.06 is not equal to 10 times 354.6 as the zero only changes the decimal place value.
Gloria is accurate while Juan is mistaken. 354.6 and 354.06 do not add up to the same number. It is not possible to get a value that is 10 times the other number (354.6) by adding a zero to the decimal point (354.06).
Only the decimal place value is altered when a zero is added the actual numerical value remains unchanged. Compared to 354.6, which only has one decimal place, 354.06's additional zero after the decimal point indicates a more accurate measurement. Juan was mistaken when he said that 354.06 was equal to 10 times 354.6.

Step-by-step explanation:
The length of a rectangle is 3 meters more than the width. The perimeter of the rectangle is 26 meters. If the width is b, which equation represents the situation? How many solutions will this equation have?
A. (b + 3) (b) = 26, which has one solution
B. 2(b + 3) + 2b = 26, which has infinitely many solutions
C. 2[(b + 3) + b] = 26, which has one solution
D. 2[(b + 3) + b] = 26, which has no solution

△ABC and △CDE similar right triangles. The coordinates of all the vertices are integers.
A. The slope of AC¯¯¯¯¯ is less than the slope of CE¯¯¯¯¯ . This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is less for AC¯¯¯¯¯ than for CE¯¯¯¯¯ .
B. The slope of AC¯¯¯¯¯ is greater than the slope of CE¯¯¯¯¯ . This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for AC¯¯¯¯¯ than for CE¯¯¯¯¯ .
C. The slope of AC¯¯¯¯¯ is equal to the slope of CE¯¯¯¯¯ . This this because ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is the same for AC¯¯¯¯¯ as for CE¯¯¯¯¯
D. The relationship between the slope of AC¯¯¯¯¯ and the slope of CE¯¯¯¯¯ cannot be determined, because the triangles are congruent.
Answer:
C.) The slopes are equal
Step-by-step explanation:
Since both of the triangles are similar right triangles they have the same slope, in order for triangles to be similar, you must be able to make them look the same. In this case triangle, CDE is a down-scaled version of triangle ABC meaning if you just multiplay all the vertices by the same (and correct) number it will make a triangle the same as ABC, therefore the triangles have equal slopes.

Answer:
Store 2 has a better deal do u want an explanation
Step-by-step explanation:
okay so my explanation is if they both are selling for the same price then look at how many they are selling if store 1 is selling 12 for 3.50 and Store 2 is selling 15 then Store 2 has the better price. Hint if you ever have a problem lie this then you first look at the price if the price is the same then you look at how many they are selling if one of them is selling more than that is the better price
A conversion table indicates that 1 mile is 1.6 km. With this conversion rate, is the speed limit greater than or less than 65 mph? Explain.
greater because 1.6 is larger than 1
Answer:
higher than
Step-by-step explanation:
The speed limit is 110 km hour and there are 1.6 kilometers in a mile. This means that there are 110 ÷ 1.6 miles per hour:
110 km hour÷1.6 km mile=110÷1.6 miles hour.
We can find 110 ÷ 1.6 using long division and it is 68.75. So the speed limit is higher than 65 mph
