Answer:
1078
Step-by-step explanation:
first: multiply 980 by 0.10 to get 10% of 980
second: take that value (98) and add it to 980
then: you get 1078 after adding
Answer:
- The equation 2n = p should be 2p = n.
- The actual cost of the onions is $3.00 per pound.
- Potatoes cost $1.50 per pound.
Step-by-step explanation:
The wording "onions cost twice as much as potatoes" is understood to mean the cost per pound of onions (n) is equal to two times the cost per pound of potatoes (2p). Then the appropriate equation would be ...
2p = n
Then the solution is ...
6p +3(2p) = 18
12p = 18
p = 18/12 = 1.50
n = 2p = 2(1.50) = 3.00
__
The equation should be 2p = n; onions cost $3.00 per pound; potatoes cost $1.50 per pound.
Answer:
not really
Step-by-step explanation:
The number of friends (x) is expected to be an integer. 6.5 friends does not really make sense.
_____
There are all kinds of ways this might make sense, but none of them are supported by the information given in the problem statement.
Answer:
I take it you mean the average gallons lost an hour, in which case you would do 58,432.4 - 56,475.2 to get 1,597.2 to which you divide by 2 getting your final answer of 978.6
<span>Given the question "If 9i is a root of the polynomial function f(x), which of the following must also be a root of f(x)?" The correct answer is -9i.
Given a polynomial with a complex root, then the conjugate of the complex root must also be a root to that polynomial function.
The conjugate of a complex number is the number with equal real part and imaginary part but with the sign between the real part and the imaginary part opposite. For example, the complex conjugate of 3 + 4i is 3 − 4i.
Therefore, given that 9i is a root to a polynomial function f(x), the conjugate of 9i = -9i will also be a root to the equation.</span>
