6. 20 ft Below sea level is -20 and 15 ft. Below sea level is -15, add -20+-15 (the new integer is -35)
8) y intercept is (0, 15) or 15
slope is 10 (the y intercept represents how much it would cost to open an online gaming account and the slope represents how much each game costs after you open an online gaming account, including the $15 fee to open the account)
9) y=10x+15
10) you can look at the graph where it says number of games and go to 6 and go up until you reach the line and look at the side where it says cost (dollars) and then you will see that 6 games cost $75
The number of students who chose not to study Spanish in their senior year is 124.
In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.
Given that
56% Students studied Spanish, which means 44% did not study Spanish.
In mathematics, a ratio shows how many times one number contains another.
Hence if the ratio is:
56 : 44 = 14:11
Then, the number of students who did not study Spanish is:
(14/11)×98 = 124.
Therefore the correct answer is 124.
