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:
Answer:
-8 < 8
Step-by-step explanation:
(-8) is smaller than 8...because for a value to be bigger...it has to be ahead of the other value(that its being compared to)...going in the positive direction of the numberline
Answer:
Number of seeds in each cup = 5 seeds in each cup
Step-by-step explanation:
Given:
Total number of seeds Liam has = 60 seed
Total number of plastics cup = 12 cups
Find:
Number of seeds in each cup
Computation:
Number of seeds in each cup = Total number of seeds Liam has / Total number of plastics cup
Number of seeds in each cup = 60 / 12
Number of seeds in each cup = 5 seeds in each cup
Answer:
1) 35 gallons by the first car 2) 40 gallons by the second car
Step-by-step explanation:
Suppose the first car used x gallons, when the second car used the rest- 75-x
If the first car's efficiency is 35 miles per galon, its milleage is 35*x, the second car's milleage is 15*(75-x). And the summary milleage is equal to 1825.
35x+15(75-x)=1825
35x+1125-15x= 1825
20x=700
x=35- gallons consumed by the first car,
75-35=40- gallons consumed by the second one
