Surface area = 2 pi (3x-2)^2 + 2 pi (3x -2) ( x + 3)
= 2 pi (9x^2 - 12x + 4 + 3x^2 + 7x - 6
= 2pi(12x^2 - 5x - 2)
Its D
1) The value of 6s in 36,621 are 6,000 and 600.
first 6 is in the thousands place value while the second 6 is in the hundreds place value.
6 x 1000 = 6,000 and 6 x 100 = 600
2) The first 4 is ten times greater than the second 4 is shown in 354,426
the first 4 is in the thousands place value while the second 4 is in the hundreds place value
4 x 1000 = 4000 and 4 x 100 = 400
based on the question the first 4, which is 4000, is ten times greater than the second 4, which is 400.
we can check if this statement is true either by dividing 4000 by ten or multiplying 400 by ten.
4000/10 = 400 ; 400 x 10 = 4000. therefor, out of the 4 numbers given, the correct one is 354,426
3) The relationship of the two 5s in 552 is shown in 500 ÷ 50 = 10
based on its place value, the first five is in the hundreds place and the second five is in the tens place.
500 ÷ 50 = 10. This equation states that 500 is ten times greater than 50.
4) In 2,077 the first 7 is greater than the second 7 by 10 times.
using place value, first 7 is in the tens place while second 7 is in the ones place.
first 7 is 70; second 7 is 7. we divide 70 by 7 to know how many number of times 70 is greater than 7.
70 ÷ 7 = 10 times.
Answer:
10%
Step-by-step explanation:
you would do 50/5 because all the sections are even so you would get 10%.
To solve this we are going to use the half life equation
Where:
is the initial sample
is the time in years
is the half life of the substance
is the remainder quantity after
years
From the problem we know that:
Lets replace those values in our equation to find
:
We can conclude that after 1600 years of radioactive decay, the mass of the 100-gram sample will be
91.7 grams.
Can I get the question please. I might help you with your question.
