Answer: The answer to question 1 is 180 in. The answer to question 2 is 54 in. sq. And the answer to question 3 is (2,3)

Step-by-step explanation:

To solve question 1, we need to identify the remaining length of the shape. I've done that in an image below. The next step is to add all of those sides together. It would be 20+20+20+20+20+10+10+60 = 180 inches in length.

To solve question 2, all you need to do is follow the formula A = [h(b) x b] /2

Which may look scary but never fear! Written in understandable words it essentially says, multiply the height by the base then divide by 2.

A = (6 x 18) ÷ 2

A = 108 ÷ 2

A = 54 meters squared

For the last question, I'm not sure what the formula is, but I have a way of doing it that isn't too confusing. Simply add the x values and add the y values, then divide them by 2 to get their halve. Now the new x and y values are your midpoint. (Do not add the x + y values, only the x + x and y + y)

See :

-3 + 7 = 4 4 ÷ 2 = 2

8 + (-2) = 6 6 ÷ 2 = 3

So your new coordinates are (2,3)

I hope this helped you understand :)

A bird flies from the bottom of a canyon that is 71 4/5 feet below sea level to a nest that is 875 7/10 feet above sea level. Wh

Rainbow [258]

The difference in elevation between the bottom of the canyon and the bird's nest is 947 1/2 feet

<h3>What is the difference in elevation between the bottom of the canyon and the bird's nest?</h3>

The given parameters are:

Nest = 71 4/5 feet above the seal level

Bottom of canyon = 875 7/10 below sea level

Below sea level means negative

So, we have:

Nest = 71 4/5 feet

Bottom of canyon = -875 7/10

The difference in elevation between the bottom of the canyon and the bird's nest is calculated as

Difference = |Nest - Bottom of canyon|

This gives

Difference = |71 4/5 - (-875 7/10)|

Evaluate the difference

Difference = |947 1/2|

Remove the absolute bracket

Difference = 947 1/2

Hence, the difference in elevation between the bottom of the canyon and the bird's nest is 947 1/2 feet
