A car made a 60-mile trip at an average speed of 20 mph. On the return trip, the car's average speed was 30mph. What was the average speed of the car for the entire two-way trip?
A) 30 mph
B) 26.5 mph
C) 26 mph
d) 24 mph
Answer:26
Step-by-step explanation:
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

△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.
he graph shows the number of boxes a machine package over time is the relationship proportional how many boxes does the machine package in 4 minutes
Answer:
100 boxes are packed in 4 minutes
Step-by-step explanation:
If you take a look at the graph, for example, y equals 50 and x equals 2, which means that the constant of proportionality is 25. 25 x 4 = 100

Answer:
81.8%
Step-by-step explanation:
please mark as brainliest
percent of the class turned their homework in on time is 81.82%.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
here, we have,
given that,
In Mrs. Stone's class, 18 out of 22 students turned in their homework on time.
now,
the percent of the class turned their homework in on time is,
18/22 * 100
=81.82%
hence, percent of the class turned their homework in on time is 81.82%.

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.
