Answer:
The rhombus ABCD has an area of 22 square units.
Step-by-step explanation:
The coordinates of rhombus ABCD are shown in the image attached below. The area of the rhombus can be found in terms of their diagonals, which are now calculated by Pythagorean Theorem:
![AC = \sqrt{[6-(-4)]^{2}+[8-(-4)]^{2}}](https://tex.z-dn.net/?f=AC%20%3D%20%5Csqrt%7B%5B6-%28-4%29%5D%5E%7B2%7D%2B%5B8-%28-4%29%5D%5E%7B2%7D%7D)
![BD = \sqrt{(4-6)^{2}+[0-(-2)]^{2}}](https://tex.z-dn.net/?f=BD%20%3D%20%5Csqrt%7B%284-6%29%5E%7B2%7D%2B%5B0-%28-2%29%5D%5E%7B2%7D%7D)
The area of the rhombus is: ( and )
The rhombus ABCD has an area of 22 square units.
Answer:
0.555km p/h
shown as 555m p/h
Step-by-step explanation:
First we convert km to meters
6k = 6000m
Time = distance / rate.
20/6 = 3.33333333 = 3hr + ( 0.33 x 60 = 19.8) - 3.20hr
then 3.33 / 6 = 0.555 km = 555 meters p/h
Given, Sylvie needs $110 for a concert ticket.
Sylvie has $16.
Her hourly earnings = $h
Sylvie is working 10 hours at her job.
She is getting in 1 hour = $h
So, 10 hours she will get = $ = $
So the total amount she has now = $16 + $(10h) = $()
So we can write the equation as,
110=16+10h
We can move 16 to the left side also. 16 is added to the right side. We can move it by using reverse operation of addition. Reverse operation of addition is subtraction. So we will subtract 16 from both sides. Subtracting 16 we will get,
110-16=16+10h-16
110-16=10h
We have got the required answer.
To find Sylvie's hourly income the correct options are option A and option D.
(-3.5,-5.5) are the coordinates for R. x goes first in the ordered pair. (x,y)
When r is closest to 1, it is a strong positive correlation. When r is closest to -1 it is a strong negative correlation. When r is about 0.8 or anything similar, it is a weak positive. Similar to if r is -0.8 it would be a weak negative correlation. Hope this helps.
