The answers are : A and C
If the product of two integers is negative that means that the integers that were multiplied together consisted of a positive integer and a negative integer.
Ex: -2 X 4 = -8
Answer:
The percent error rounded to the nearest tenth is 8.6%.
Step-by-step explanation:
The general equation for percent error is as follows: percent error = [(experimental value - actual value) / actual value] x 100. In this problem, her experimental value, or the expected score was 85%. However, her actual score was 93%. When we subtract the two values, we get a difference of 8 and when we divide this number by the actual value of 93, we get a quotient of .086. Multiplying this answer by 100 will give a final percentage of 8.6%.
Answer:
Carly didn't make a mistake
Step-by-step explanation:
24 / (4 x 2 - 5)
PEMDAS
P: Parenthesis = (4 x 2 - 5)
E: Exponents: None
M: Multiplication = (4 x 2 - 5) = (8 - 5)
D: Division = Not yet, because the Parenthesis is not done.
A: Adding = None
S: Subtracting = (8 - 5) = 3
Divide = 24/3 = 8
Answer:
Using the formula:
where
A is the total amount
P is the principal
I is the Simple Interest
As per the statement:
Principal(P) = 5300 rupees.
rate of interest(r) = 6.5% = 0.065
Total amount(A) = 6678 rupees.
Then using above formula we have;
Subtract 5300 both sides we get;
or
We have to find the time period.
Using formula of Simple interest:
where r is the rate of interest (in decimal)
here, r = 6.5% = 0.065
Substitute the given values top find t:
⇒
Divide both sides by 344.5 we have;
Therefore, the time period t in years is 4 years
