Out of the 120 students at a summer camp, 72 signed up for canoeing. There were 23 students who signed up for trekking, and 13 o
Tpy6a [65]

Answer: The answer is 32%


Step-by-step explanation: <u>10% is the wrong answer!</u> I see everybody saying 10% but it is wrong let me show you:

I linked the table down below and by doing simple math like addition and subtraction I filled in the missing numbers on the 2-way table. So what you have to do to get the percentage is take 38% (which is the total of of no-canoe and no-trek students) and divide it by 120 (the overall total). This will get you a long decimal of 0.31666667, but then you are going to multiply the decimal by 100; 0.31666667*100, to get 31.666667 which is your percentage and we will round it up to <u>32%</u>

good luck

PS. I took the test and got it right

Cross multiply and solve for x, the number of pages in 75 minutes:

60x = 1500

x = 25

So, he can read 25 pages in 75 minutes at the same rate

What is the volume of the triangular prism? Round to the nearest tenth.
Alex17521 [72]

Answer:

1,185.6 in.

Step-by-step explanation:

volume of the triangular prism = base area x height

the base in the shape of a triangle

area of a triangle = 1/2 x base x height

1/2 x 12 x 10.4 = 62.4 in²

volume = 62.4 x 19 = 1185.6 in

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
