Answer:

A. JK = 12, JK is parallel to LM

D. JK = 8, JM = 12

Step-by-step explanation:

Based on the given figure above, the additional facts that would guarantee that JKLM is a parallelogram are answers A and D.

By definition, a parallelogram is a figure that has opposite sides parallel or it has two pairs of sides that are parallel.

Elina [12.6K]

 decrease in temperature if you hike up the mountain 3000 meters is  -30° .

<u>Step-by-step explanation:</u>

Here we have , Hiking up a mountain, you notice that the air temperature drops 10 degrees every 1000 meters increase in elevation . We need to find Write a multiplication expression to represent the decrease in temperature if you hike up the mountain 3000 meters. Let's find out:

For every 1000 meters rise in elevation , there is decrease in 10° of temperature . So , For rise in n meters in  elevation , there is decrease in n×10° of temperature i.e

Decrease in temperature = (n/1000)×(-10) i.e.

⇒  (n/1000)×(-10)

⇒ \frac{n}{1000}(-10)

At n = 3000 meters:

⇒ \frac{3000}{1000}(-10)

⇒ 3}(-10)

⇒ -30°  

Therefore ,  decrease in temperature if you hike up the mountain 3000 meters is  -30° .

What is the value of r of the geometric series n=11.3(0.8)n-1
jeyben [28]

the value of r of the geometric series n=11.3(0.8)n-1

an=11.3(0.8)^{n-1}

General formula for nth term of any geometric series is   a_n=a_1(r)^{n-1}

Here 'r' is the common ratio

a_1 is the first term of the series

Now we compare the given formula with general formula

Compare  an=11.3(0.8)^{n-1}  with  a_n=a_1(r)^{n-1}

The value of r= 0.8
