Basically you need to find what 15% of 136.45 is. You do this by changing the percent to a decimal, so 15% would be .15. Following this, you would multiply 136.45*.15. This will give your answer.
Four? Isn't it stated in the question? Unless I am assuming wrong.
The sum will be:
sigma(i = 1 to infinity, 30*(2/5)^i)
->
Which is equal to 30/(3/5) = 50
Answer:
Step-by-step explanation:
1) Distribute -5 to each of the terms: -5a + 5b - 5
2) Take out the GCF which is 6y: 6y(3x + 1)
3) Distribute - 2/5: 9x - 4y
4) Take out the GCF which is 3: 3(-4d + 3e - 5)
Hope this Helps! If it doesn't, you can ask me additional questions!
Answer:
There are 600 students in this school.
Step-by-step explanation:
Let p represent the total population of the school.
Then (1/3)p represents the number of students who like math. Subtracting this (1/3)p from p gives an expression representing those who do not like math:
p - (1/3)p = (2/3)p
400 students do not like math, so (2/3)p = 400.
Solve this for p by multiplying both sides by (3/2):
(3/2)(2/3)p = (3/2)(400), which simplifies to p = 600.
There are 600 students in this school.
