Answer:
4
Step-by-step explanation:
If she got a 90% on her test, and the test was 40 questions long, we need to do a bit of division and multiplication.
We have to divide 40 by 100, as percentages are out of 100.
So now we have 0.4.
Now we multiply this by 90.
36. She got 36 answers correct out of 40, which means she got four wrong.
Answer:
Step-by-step explanation:
- 1/3log₅(p) + log₅(p²-25) - log₅(p-5) =
- 1/3log₅(p) + log₅(p+5)(p-5) - log₅(p-5) =
- 1/3log₅(p) + log₅(p+5) + log₅(p-5) - log₅(p-5) =
- 1/3log₅p + log₅(p+5) =
- log₅(p)¹/³(p+5)
The total square area is equal to 7*7=49 units.
Subtract the number of black spaces (remember that 2 black traingles make up 1 whole black piece).
49-13= 36 white spaces.
36 white spaces/49 total= 0.7346...
Final answer: C
Answer:
5y-10x=35
Step-by-step explanation:
The standard way to write a linear relationship between the x and y variables is through a homogeneous equation as a combination of the x and y variables with real coefficients.
