To find the amount of time, take the distance and divide by the rate. The answer will be in hours.
Notice that the distance to your drandparents' home is less than 4 miles, so it will take less than one hour.
3.67 miles / 4 miles/hour = 0.9175 hours
To change this into minutes, multiply by 60, the number of minutes in one hour:
0.9175 hours x 60 minutes/hour = 55.05 minutes, which rounds to 55 minutes.
If you are interest in numbers, you might like to read the following:
2/3 = .6666666... which rounds to .67
So 3.67 miles might actually mean 3 2/3 miles.
If it does: (3 + 2/3) / 4 x 60 = exactly 55 minutes

£940 is divided between gavin, jim & Krutika so that gavin gets twice as much as jim, and jim gets three times as much as kr
Zielflug [23.3K]

Answer:

$282

Step-by-step explanation:

We can think of it as an equation system. Lets find out the equations.

There are 3 people: Krutika, Gavin and Jim. Lets call k Kutrika's money and g and j Gavin's and Jim's money respectively.

So, as Gavin gains twice as Jim we can say that:

g = 2j

Then, as Jim gets 3 times more than Kutrika:

j = 3k

And, as the whole sum is 940:

k + j + g = 940.

Notice that both Kutrika's and Gavin's money have a relation to Jim's money, so we can try to write them as function of Jim's money.

If we part from j = 3k and divide both sides by 3:

j/3 = k

So, using this last equation and g = 2j, replacing in the equation that sums the money of everyone:

k + j + g = 940

j/3 + j + 2j = 940

Putting together all the terms that have j imply using 3 as common denominator:

j/3 + 3j/3 + 6j/3 = 940

10j/3 = 940

Dividing both sides by 10/3 (or multiplying by 3/10):

j = 940/ (10/3) = 282

So, Jim has $282. Now we can use the relations we defined to find k and g:

k = j/3 =$94

g = 2j = $564

I have 3 different ones now. I apologize for the relentless questions.
Minchanka [31]

Answer:

\frac{1}{4x}

Step-by-step explanation:

The negative exponential can be represented with the help of fractions. By this way, we also make the negative exponential disappear. For example, we can write:

a^{-1} = \frac{1}{a}

The explanation is this:

Since a^{0}=1, \frac{1}{a}=\frac{a^{0} }{a^{1} } = a^{0-1} =a^{-1}

According to this definition, we can simplify our problem in the following way:

(4x)^{-1} = \frac{1}{(4x)^{1} } = \frac{1}{4x}

irina [24]

Answer:

I think this question is incomplete or maybe incorrect but if it's OK then the answer would be 7x + 5y.

Step-by-step explanation:

the answer remains the same because the question has no like terms so no further calculations can be made.

HELP ME PLS ITS DUE IN 5 MINS
Firdavs [7]

9514 1404 393

Answer:

  • 132v^2, -v
  • 24v^6, -2v^3
  • 18v^12, 7v^6
  • -56v^14, -15v^7
  • 3v^20, -2v^10

Step-by-step explanation:

The product is the product of the numbers, multiplied by the product of the variable factors. The variable is the same in every term, so the product of the variable factors will have an exponent that is the sum of the exponents.

The difference will have a coefficient that is the difference of the coefficients.

__

(11v)(12v) = 132v^2 . . . . 11v -12v = -v

(4v^3)(6v^3) = 24v^6 . . . . 4v^3 -6v^3 = -2v^3

(9v^6)(2v^6) = 18v^12 . . . . 9v^6 -2v^6 = 7v^6

(-8v^7)(7v^7) = -56v^14 . . . . -8v^7 -7v^7 = -15v^7

(-3v^10)(-v^10) = 3v^20 . . . . -3v^10 -(-v^10) = -2v^10
