It should be asking for how much longer it takes for Hunter to clean his house, since it says 3 and 1/2 hours. Jeremy only takes 2 and a half hour to clean, so it would be less than Hunter's time. I will help you with this problem, but I will do it with the question "How much longer does it take for Hunter to clean his house?", because the question above doesn't make sense to me.

This is all based on subtraction. You would take the fraction that is more than the other, and use it to subtract the less. You would always want the denominator to be the same, so lets switch it to 2 2/4. Now, you would do 1/4 minus 2/4, which gets you -1/4. You can use the whole hours and fill it in. Since the whole hours is 4/4, you would take 4/4+(-1/4). Simplify and you will get 4/4-1/4. And you would have 3/4.

Now, since the question is asking for how long it take for JEREMY for clean his house, you would say, "it takes -3/4 hours longer for Jeremy to clean his house, since Hunter really takes longer." (Everything in the quote is part of the answer)

Sorry if it is a little confusing.

Easy, it says "for ANY positive integer" so just test any positive integer

remember that n! means times all integers from 1 to that number n

lets try 1

(1+1)!/(1!)-1=
(2!)/(1!)-1=
2/1-1=
2-1=
1

if you don't believe me, try 2
(2+1)!/(2!)-2=
(3!)/(2!)-2=
(6)/(2)-2=
3-2=
1

te answer is 1, B


and number 9
easy, remember the exponential law
(x^m)(x^n)=x^(m+n)
jsut add the exponents
first gropu like bases
(r^2r^2/3)(t^1/2t^-3/2)
add bases
(r^2 and 2/3)(t^-1)=
(r^2∛(r^2))(1/t)=
\frac{r^{2} \sqrt[3]{r^{2}} }{t}

Determine the length of GH. Round to the nearest tenth.<br> 3.9 cm<br> G<br> 52<br> 642<br> H
sesenic [268]

Answer:

|GH| = 5,7 cm

Step-by-step explanation:

To know |GH|, you first need to find the length of |GD|.

We can calculate |GD| by;

cosG = |GC| / |GD|

<=> |GD| = |GC| / cosG

 => |GD| = 3,9 cm/ 0,62 = 6,33 cm

We now can easily calculate |GH| with the sinus of angle D;

sinD = |GH| / |GD|

<=> |GH| = sinD.|GD|

 => |GH| = 0,899.6,33 cm = 5,694 cm => 5,7 cm

I hope i did not make a mistake ...
