<span>answer is very simple. first you divide 11 by 12 (12 months in a year). you get .9166. next divide 2000 by 100 and multiply by .9166 to get D.) 18.33. i hope this helps.</span>
Answer:
The area of ∆DEF = 4.5in²
Step-by-step explanation:
From the above diagram,
∆BAC ~∆DEF
It is important to note that if two triangles are similar, the ratio of their areas is equal or equivalent to the ratio of the areas of their sides
This means for the above question, that
We have the bigger triangle = ∆BAC has a side of 4 in and Area = 8 in²
The small triangle has a side of 3in
Finding the scale factor k = ratio of the sides of both Triangles
k = 4/3
k² = (4/3)²
k² = 16/9
Hence,
Area of ∆BAC/ Area of ∆DEF = 16/9
8in²/Area of ∆DEF = 16/9
We cross Multiply
8 in² × 9 = Area of ∆DEF × 16
Divide both sides by 16
Area of ∆DEF = 72/16
= 4.5in²
Therefore, the Area of ∆DEF rounded to the nearest tenth = 4.5in²
Answer:
variable
Step-by-step explanation:
64/8 = 8
5x8 = 40
If 1:4 = 1/4 then do 40/4 = 10
If 1:4 = 14 then do 40-14 = 26
The answer might be either 10 or 26 guitarist that play classical solos depending on what 1:4 means.
I hope this helps! :D
