Answer:
The fourth line will have 15 marbles

The third line has 7 marbles. So, you double that and add one in order to find the number of marbles in the fourth line.
7*2=14
14+1=15
40/100 - (I may be wrong)
Explanation: 40% of 110 is 44 so we make this a fraction 44/110 and then simplify to get 2/5 and after that we know that 2/5 is also 40/100, meaning 40 out of 100 students like video games.
Answer:
5 rolls of ribbon are needed
Step-by-step explanation:
To find how much ribbon you'll use, multiply 80 by 2 3/4. To multiply them, convert 2 3/4 into an improper fraction 11/4.
Multiply: 80 * 11/4 = 880/4 = 220
This means you need 220 total feet of ribbon. Since each roll has 50 feet, you'll need 5 rolls or 250 feet to wrap every box.
I’m not sure but is it C? I’m so sorry if it’s wrong

e^x=29.1/5
ln(e^x)=ln(29.1/5)
x=ln(29.1/5)
