I think B because in that equation u subtract the two and for that situation u also subtract the too and I feel like that is the most correct one
Answer:
A) 5.12mm³
Step-by-step explanation:
Step 1
Find the volume of the bigger pyramid
This is a triangular based pyramid.
The formula to use is given as Volume of Pyramid =
1/3 × Area of the triangle × Height
Area of the triangle = 1/2 × 3 mm × 4mm = 6mm²
Volume of the large pyramid = 1/3 × 6mm² × 5mm
= 10mm³
We are given the length of the small pyramid as 4mm
We would be using was is known as scale factor to find the volume of the small pyramid
The scale factor k = (Height of the small pyramid)³/ (Height of the Large pyramid)³
k = 4³/5³
k = Volume of small pyramid/ Volume of large pyramid
Volume of small pyramid = X
Volume of large pyramid = 10mm³
Hence,
4³/5³ = X/10
Cross Multiply
= 4³ × 10 = 5³ × X
X = (4³ × 10)/ 5³
X = 5.12mm³
A because two negatives make a positive
It should be B because if class average will increase then the cost of books will be increased. Therefore, class average will be independent variable and cost of books will be dependant.
Hope this helps you out... :)

First, we know that <em>one</em> meter equals 100 centimeters, therefore,<em> two</em> meters equals 200 centimeters.
Here is your expression:
200 cm + 60 cm
Using our math skills, we know that 200 cm (2m) + 60 cm equals 260 cm or 2 meters and 60 centimeters.
Your answer would be 260 cm <em>or</em> 2 meters and 60 centimeters.
