Answer:
3450
Step-by-step explanation:
(2.3x10^4)x(1.5x10^-2)
(2.3x10,000)x(1.5x.1)
23,000x.15

Given =
Two similar pyramid have base area of 12.2 cm² and 16 cm².
surface area of the larger pyramid = 56 cm²
find out the surface area of the smaller pyramid
To proof =
Let us assume that the surface area of the smaller pyramid be x.
as surface area of the larger pyramid is 56 cm²
Two similar pyramid have base area of 12.2 cm² and 16 cm².
by using ratio and proportion
we have
ratio of the base area of the pyramids : ratio of the surface area of the pyramids
x = 12.2 ×56×
by solvingthe above terms
we get
x =42.7cm²
Hence the surface area of the smaller pyramid be 42.7cm²
Hence proved
Answer:
There are 25 chickens and 20 rabbits
Step-by-step explanation:
Let
x-----> the number of chickens
y ----> the number of rabbits
Remember that
1 chicken has two legs
1 rabbit has four legs
so
2x+4y=130 -------> equation A
x=y+5 -----> equation B
Substitute equation B in equation A and solve for y
2(y+5)+4y=130
2y+10+4y=130
6y=120
y=20 rabbits
Find the value of x
x=y+5
x=20+5=25 chickens
Emily Dickinson's poetry was rescued for posterity by her sister (c). Emily Dickinson lived during the American Civil War, but she lived in her father's house in Amherst, Massachusetts. This area was not affected by the Civil War. She was fairly isolated as a poet and, as a result, the events of the Civil War did not play a major role in her poetry. She wrote mainly about the events in her direct environment, with no direct sense of the time in which she lived. Her world consisted of her own home and the surrounding countryside.
