Trapezoid JKLM is is shown below. What is the length in centimeters, of KL

IrinaVladis [17]

The complete question is:

Trapezoid JKLM is shown below.

What is the length, in centimeters, of KL ?

A. 12 cm

B. 10 cm

C. 9 cm

D. 6 cm

The mentioned figure is attached.

Answer:

$\large\boxed{option\text{ B. }(\overline{KL})=10cm}$

Explanation:

1. KL is the hypotenuse of a right triangle; hence, you can use Pythagora's theorem to find its length.

2. The height 8 cm is one leg of the right triangle.

3. The other leg may be found by difference:

$\overline{ML} -\overline{JK}=15cm-9cm=6cm$

4. Now you can use Pythagora's theorem:

$hypotenuse^2=(leg_1)^2+(leg_2)^2\\ \\ (\overline{KL})^2=(8cm)^2+(6cm)^2\\ \\ (\overline{KL})^2=64cm^2+36cm^2=100cm^2\\ \\ (\overline{KL})=10cm$

The astronauts from apollo 17 completed 3 space walks while on the moon for a total duration of 22 hour 4 minutes how many minut

Vadim26 [7]

Answer:

The duration of each of the three spacewalk is between 364 minutes and 480 minutes with a total duration of 1324 minutes

Step-by-step explanation:

A spacewalk also termed an EVA or extravehicular activity, is defined as the general activity of an astronaut outside of a vehicle in space

Spacewalks can last up to 5 to 8 hours

Here we have a word problem, and are required to find the number of minutes equivalent to 22 hour and 4 minutes

Number of minutes per hour = 60 minutes

Number of minutes in 22 hours = 60 × 22 = 1320 minutes

Total number of minutes in 22 hours 4 minutes = 1320 + 4 = 1324 minutes.

Whereby the duration of a space walk is up to 5 to 8 hours gives;

22 hours 4 minutes - 8 hour - 8 hour -x = 0

Hence x = 6 hour 4 minutes

Therefore, the duration of each spacewalk is between 6 hour 4 minutes and 8 hours or in minutes we have

The duration of each spacewalk is between (6 × 60 + 4) 364 minutes and 480 minutes.
