The tail of a 1-mile long train exits a tunnel exactly 3 minutes after the front of the train entered the tunnel. If the train i

igomit [66]

The tail of the train starts one mile from the mouth of the tunnel and it must travel that distance plus the length of the tunnel in 3 minutes.

Let t = tunnel length

t + 1 = distance the tail must travel in 3 minutes.

3 minutes = 1/20 hr

(t+1) miles / 60 m/hr = 1/20 hr

t + 1 = 60/20

t+1 = 3

Subtract 1 from each side:

t = 2

The tunnel is 2 miles long.

Can someone pls help? ab to fail geometry. any help is nice.

Mamont248 [21]

By the law of cosines, the angle $C$ satisfies

$8.77^2=2^2+9^2-2\times2\times9\times\cos C$

which reduces to

$\cos C=0.2246\implies C=\arccos(0.2246)\approx1.34422\text{ rad}$

which converts to approximately 77 degrees (this can be done my multiplying by 180 and dividing by pi).

What is the answer for 805 tens = with place value chart

alexandr1967 [171]

In the given problem, the numerical value of 805, which is in the tens place, we can first elaborate and clearly specify the order of numbers by using the expanded form: 1. 800 = eight hundred / hundreds 2. 0 = zero / tens 3. 5 = five / ones Conclusively the tens value of the number is zero or none, since zero is not a real number then it can’t be considered but nevertheless, the value is 0 expressed with respect to the whole numbers.

Give one combination of two factors whose product is 0.24, if one of the factors is a whole number greater than 1.

vitfil [10]

Answer: There are a lot of answers to this product. Some of them include (in the format (w, x), where w is the whole number, and x is the factor you must multiply it by to get 0.24):

(2, 0.12), (3, 0.08), (4, 0.06), (6, 0.04), and so on.

Step-by-step explanation: Well, you could just assign the smallest who number greater than 1 to one of the factors, which is 2. Now you just have to multiply that by another factor to get 0.24. To do this, you could set up an equation like this:

2*x=0.24

Next, you would divide both sides by 2 to cancel out the 2 on the left side of the equation, leaving you with:

x=0.12

There you have it!

Now you can check your work by multiplying 2 and 0.12, and you will get 0.24!

You can do the same thing with other whole numbers, such as 3 and 4, and complete the same process to find the decimal factor that multiplies to 0.24.
