Explain how to simplify the following radical:<br> 10√96
Natali5045456 [20]

Hey there!! So first you gotta get a calculator and put in the check Mark thingy and 96 which would be 9.79795897113271 then you multip by 10 which is just 97.9795897113271 but your teacher would probably want it to the nearest tenth so we would say 98. I’m probably wrong but I hope this helps!!

What is -0.8x - 6 &lt; -10
puteri [66]
Solving an equation is simply like solving an equation. For this problem, you must add 6 on both sides to get -0.8x alone. -10 + 6 would equal -4. Therefore, the inequality would look like this: -0.8x < -4 
Now you have to divide -0.8 on both sides to have x alone. Since you are dividing a negative to the other side, the sign flips to >. When you divide -0.8 to -4, the answer would be 5. So therefore, the answer is: x > 5 
In order to check this, you must plug in 5 into the x. -0.8 times 5 would equal -4. -4 - 6 would equal -10. -10 is the same as the other side. (-10 < -10) That means the answer would be correct. Hope this helps; cheers, mimiisawesome5

The Penn's Landing Ferry sells deluxe and economy seats for each tour it conducts. In order to complete a tour, at least 28 econ
kenny6666 [7]
The maximum profit for 1 tour would be $2650

if there are 90 seats and 10 deluxe seats must be sold, you have to multiply 10 times 25 which gives you 250.

if there are 90 seats, 10 must be deluxe (which is cheaper), and you are trying to find the max profit for 1 tour, then 80 of the seats must be economy seats. 
to find out how much 80 economy seats would cost you need to multiply 80 times 30 which gives you 2400.

then you need to add the profit of 80 economy seats and 10 deluxe seats and that would give you $2650

and $2650 would be the max profit you could make for 1 tour.
