Answer:

24+2x+2y

or

B) 122 units² if the missing measurement is 7.

Step-by-step explanation:

12+12+x+x+y+y=24+2x+2y

The surface area cannot be determined with just a number and no variables because there is a missing measurement.

The missing measurement looks a lot like 7 so let's assume it's 7

12+12+21+21+28+28=122 units²

By the definition of complementary angles, since
svlad2 [7]

The blank spaces in the task content can be filled with; Substitution property, 90° and subtraction property.

<h3>What are the missing statements in the proof?</h3>

Since it follows from the vertical angles theorem that angle 1 = angle 4 as they are congruent.

Additionally, angles 1 and 2 are said to be complementary and hence, the sum of their measures is equal to 90°.

Finally, by virtue of the subtraction property of equality, the measure of angle 2 is; 90° - 40° = 50°.

A super train traveled 420 miles in 3 hours. If it maintain the same speed, how far could the train travel in 16 hours?
Readme [11.4K]

Answer:

We conclude that the train can travel 2240 miles in 16 hours.

Step-by-step explanation:

Given that a  super train traveled 420 miles in 3 hours.

  • Distance covered = 420 miles
  • Time taken = 3 hours

Step 1 of 2

Determine distance per hour

<u>Important Tip:</u>

  • The distance per hour can be determined by dividing the distance covered by the time taken.

Distance per hour = Distance Covered / Time taken

              = 420 / 3

              = 140 miles per hour

Step 2 of 2

Determine the distance traveled in 16 hours

We already know that a super train travels 140 miles per hour. In other words, the speed of the super train is 140 miles per hour.

<u>Important Tip:</u>

  • To determine the distance covered in 16 hours, all we need to do is to multiply the distance covered per hour i.e. 140 with the total number of hours i.e. 16.

Distance traveled in 16 hours = Distance per hour × 16

                                                 =  140 × 16

                                                 = 2240 miles

Conclusion:

Therefore, we conclude that the train can travel 2240 miles in 16 hours.
