Answer:
cubes are 3-d while squares are 2-d so in order to solve them you need different equations.
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:
The volume of the full bottle of Jun's favorite hot sauce in ml is 
.
Step-by-step explanation:
Jun used x milliliters, or 90% percent, of his favorite bottle of hot sauce.
So, to find the volume of a full bottle of Jun's favorite hot sauce in milliliters, we can use the unitary method.
Then, 90% of the full bottle sauce is equal to x ml.
So, 1% of the full bottle sauce is equal to 
ml.
Therefore, 100% of the full bottle sauce is equal to 
ml.
Therefore, the volume of the full bottle of Jun's favorite hot sauce in ml is . (Answer)
