Answer:
the ratio of the surface area of Pyramid A to Pyramid B is:
Step-by-step explanation:
Given the information:
- Pyramid A : 648
- Pyramid B : 1,029
- Pyramid A and Pyramid B are similar
As we know that:
If two solids are similar, then the ratio of their volumes is equal to the cube
of the ratio of their corresponding linear measures.
<=>
=
=
= ![\frac{216}{343}](https://tex.z-dn.net/?f=%5Cfrac%7B216%7D%7B343%7D)
<=> ![\frac{a}{b} =](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7Bb%7D%20%3D)
![\frac{6}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B7%7D)
Howver, If two solids are similar, then the
n ratio of their surface areas is equal to the square of the ratio of their corresponding linear measures
<=>
=
So the ratio of the surface area of Pyramid A to Pyramid B is:
Claire receives 24 marbles. David gets 30 marbles and Elizabeth gets 36 marbles.
4x+5x+6x=90
15x=90
x=6
4(6)=24 for Claire
5(6)= 30 for David
6(6)= 36 for Elizabeth
12+5
Because double negatives change into a positive.
