PLEASE HELP 100 POINTS! WHOEVER IS CORRECT ALSO GETS BRAINLEST!

Answer:

oooooooooook????

Answer:

The answer is 4√3 MPH. Here's why:

(I refer to North friend as Bob, West friend as Joe, and Northeast friend as Kelly. I also refer to locations as 'points'.  

Another note, just to clarify: To divide 2 radicals (Ex: 6√4 / 2√2), you need to divide the numbers outside the radical symbol by each other, and then divide the numbers inside the radical symbol by each other.  

(6√4 / 2√2 would equal 3√2, because 6 divided by 2 is 3, and 4 divided by 2 is 2.  

1. Ignoring Kelly, for now, we need to find a point that is of equal distance away from the other two friends. We can do this by drawing a square, using the 3 points, with side lengths of 4, since we know that they live 4 miles apart. The middle of this square is the place they have to meet since it is of equal distance from each point

2.  Now we need to find the distance from Bob to Joe, (aka the slope). Pythagorean's Therom says that for a right triangle, (height)²+(base)²=(hypotenuse)². Therefore, (4)²+(4)²=(x)², where x is the hypotenuse. This can be simplified to 32=x². Therefore, the slope is √32. When we simplify the radical, it becomes 4√2. However now, we need to divide this by 2, because each friend is only going halfway across the slope. This means that each friend will travel 2√2 miles.  

3. We know the Time(T)=Distance(D)/Speed(S). Therefore, the time for each friend to reach the location will be 2√2/4. The speed is 4 because the friends go 4 MPH. This information will come into play later on.  

4. Now we need to find out the MPH Kelly should go to reach that same point as the rest of her friends. First, however, we need to find the distance from her point to the meeting point. We can use Pythagorean's Therom again because the meeting point, my point, and Kelly's point all form a right triangle. Again, (height)²+ (base)²= (hypotenuse)². Therefore, (4)²+(2√2)²=y², where y is the distance from Kelly to the meeting point. This simplifies to (16) + (8) = (y²).  16+8=24, therefore y is √24 miles. We can simplify this to 2√6. Now we know that the distance from Kelly to the center point is 2√6 miles, we can find the speed.  

5. As already stated, T=D/S. In order for all friends to meet at the same time,  the amount of time it takes for Group 1 to reach the center point must be equivalent to Kelly's.  

We learned earlier that 2√2/ 4= T. This means that 2√2 / 4 = 2√6 / z. This is because 2√6 was the distance Kelly lived away from the center point, and we know that since the time will be the same, the fractions will be the same.  

6. Now we can cross simplify: (4)(2√6)=(2√2)(z). This reduces to              (8√6)=(2√2)(z). When we divide each side by 2√2, we get our answer, 4√3

Therefore, Kelly needs to ride 4√3 MPH on her bike in order to reach her friends at the same time. Hope this helps :)

Step-by-step explanation:

All 3 friends will meet at 2√2 miles away from my house in the North-East direction.

(AC)² =  (AB)²+(BC)²

Where,

AC = Distance between first and second friend's home = ?

AB - Distance of first friend's home = 4 miles

BC -  Distance of second friend's home = 4 miles

Put the values in the formula,

[tex](AC)^2 = (4)^2+(4)^2\\\\AC= \sqrt {32}\\\\AC = 4 \sqrt{2}[/tex]

Since the midpoint of the hypotenuse is the point where all friends meet.

So,

Therefore, all 3 friends will meet at 2√2 miles away from my house in the North-East direction.

Answer:

15.1feet

Step-by-step explanation:

From the triangle, we are given the following

<S = 25 degree

US = 15 feet = Adjacent

Required

ST = Hypotenuse

Using the trig identity

Cos theta = adj/Hyp

Cos 25 = 15/ST

ST = 15/cos25

ST = 15/0.9912

ST = 15.13feet

Hence the measure of ST is 15.1feet

The answer is 3(3m-2)^2

Step-by-step explanation:

We have the following expression:

[tex] {27m}^{2} - 36m + 12[/tex]

We can take common factor 3 and we got.

[tex]3( {9m}^{2} - 12m + 4)[/tex]

We can factorize and we got:

[tex]3(3m - 2)(3m - 2)[/tex]

Then the final answer is:

Answer:

The length of the shipping carton is 10 meters.

Step-by-step explanation:

I took the height and multiplied it by the width to get the area of the rectangular shipping carton.  So, 12 * 5 = 60.  Then I took the cubic meters and divided that by 60 to get the length of the shipping carton.  So, 600/60 = 10.  The length of the shipping carton is 10 meters.

The length of the shipping carton is,

⇒ Length = 10 meters

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The volume of a right rectangular shipping carton is 600 cubic meters.

And, The height of the shipping carton is 12 meters, and the width is 5 meters.

We know that;

Volume of a right rectangle = Length x Width x Height

600 = Length x 12 x 5

600 = 60 x Length

Length = 600/ 60

Length = 10 meters

Thus, The length of the shipping carton is,

⇒ Length = 10 meters
