Step-by-step explanation:
believe it or not, the area of any triangle is
baseline × height / 2
we have here 2 triangles, both with the same baseline (8 cm), but with 2 different heights : 6.5 cm and 4.6 cm.
so, their areas are
8 × 6.5 / 2 = 4 × 6.5 = 26 cm²
8 × 4.6 / 2 = 4 × 4.6 = 18.4 cm²
so, in total, the shaded region is
26 + 18.4 = 44.4 cm²
Step-by-step explanation:
Elijah runs at constant speed
2.4 hours -----------> 13.8 miles
1 hour ---------------> 13.8/2.4
1 hour ---------------> 5.75 miles
Elijah run 5.75 miles in each hour at constant speed
Steps to my answer:
18x-9xy+12x
Add similar elements together, your answer comes out to be:
=30x-9xy
I hope this is what you were looking for! :)
Hey there!
The first thing we can do is find the number of third in 4.
We can do this by multiplying 4 by 3 since there are 3 thirds in a whole.
4 x 3 = 12
So, 4 = 12/3
If she studies for 2/3 an hour each night, then we can divide 12 by 2 to figure out how many 2/3 go into 12/3.
12 ÷ 2 = 6
So, she studied for 6 days.
Hope this helps!
Answer:
(-3, -7)
Step-by-step explanation:
Let 
The midpoint coordinates 
of any two points 
and 
are given by 
and 
Since B is the midpoint of AC
Since E is the midpoint of B and D and we are given the coordinates of E as (-4,-3). it follows that
Therefore
Similarly
