Answer:
The coefficient of the fifth term is 126.
Step-by-step explanation:
The question implies that after the expansion of , what would be the coefficient of the fifth term. This long expansion can be easily done by the application of the Pascal principle of expansion.
Thus,
= + + + + + + + + +
So, from this expansion, the fifth term is . And its coefficient is 126.
Answer:
If you expand this using pascals triangle you will see that the fifth term is 126a^5b^4
the coefficient is the number 126

Lena needs $50 to buy some notebooks. She had saved $2 and plans to work as a babysitter to earn $8 per hour. Which inequality shows the minimum number of hours, n, that Lena should work as a babysitter to earn enough to buy the notebooks?
2 + 8n ≤ 50, so n ≤ 6
8n ≤ 50 + 2, so n ≤ 6.5
8n ≥ 50 + 2, so n ≥ 6.5

B. 0.09 is 10 times as much as 0.9 Possibly right?
c. 0.9 is 1/10 of 0.09 Possibly right?
D. 0.09 is 1/10 of 0.9 No
The relationship between the decimals 0.09 and 0.9 is that 0.09 is 10 times as much as 0.9.
The statement that is true about the relationship between the decimals 0.09 and 0.9 is: that 0.09 is 10 times as much as 0.9.
To understand this, we can compare the place value of each digit. The digit 0 in 0.09 represents the tenth-place value, while the digit 9 represents the hundredth place value. In contrast, the digit 9 in 0.9 represents the tenth-place value. As a result, the fraction 0.09 is 10 times greater than 0.9.
