The answer would be D) no, these triangles are not similar. I'm pretty sure they would be similar if one of the answer choices said ΔABC ~ ΔCED
Answer:
Step-by-step explanation:
External length=80cm
External breadth=60 cm
External height=50 cm
External volume=l×b×h=80×60×50=240000cm^3
Internal length=80-2-2=76cm
Internal breadth=60-2-2=56 cm
Internal height=50-2-2=46cm
Internal volume=l×b×h=76×56×46=195776cm^3
Volume of wood= External volume-Internal volume=240000-195776=44224cm^3
Answer:
-3.3125
Step-by-step explanation:
Average rate of change is the slope between two points.
Slope getween points 
and 
is 
.
Using the points (2, -3.5) and (4, -10.125), the slope is
Difference is subtracting, but you need to have common denominators to do so,.
The LCD for 8 & 12 is 24. Now find equivalent fractions with a denominator of 24.
14 5/8 = 14 15/24
17 5/12 = 17 10/24
17 10/24 - 14 15/24 can't be done since the 10 is smaller. We must borrow from the 17. We will borrow 1 whole, or 24/24.
16 34/24 - 14 15/24 = 2 19/24 B
