We know that
scale factor=1/8
volume smaller figure=[scale factor]³*volume larger figure
so
volume larger figure=volume smaller figure/[scale factor]³
volume smaller figure=7 km³
volume larger figure=7/[1/8]³----> 7/(1/512)---> 7*512---> 3584 km³
the answer Part a) is
the volume of the larger figure is 3584 km³
surface area smaller figure=[scale factor]²*surface area larger figure
surface area larger figure=surface area smaller figure/[scale factor]²
surface area smaller figure=9 km²
surface area larger figure=9/[1/8]²----> 9/(1/64)---> 9*64---> 576 km²
the answer part b) is
the surface area of the larger figure is 576 km²
Answer:
ok
Step-by-step explanation:
Slope formula is y=mx+b so m is the slope and b is the y-int all u do is replace the numbers with the letters and they give u the formula which would be y=-8x-3
Answer:
The constant of proportionality for the group of boxes is: 25
Step-by-step explanation:
Proportion means that change in one quantity causes change in other quantity. Direct variation means that increase in one quantity causes increase in the other quantity.
Let l be the length and v be the volume
Then according to given statement
V∝l
Removing the proportionality symbol introduces a constant in the equation

Putting V = 325 and l = 13

Hence,
The constant of proportionality for the group of boxes is: 25
