Answer:

The formula to determine the length of rectangle with perimeter and width is L = $\frac{P - 2W}{2}$

Step-by-step explanation:

Given as :

The perimeter of rectangle = P

The length of rectangle = L

The width of rectangle = W

∵ Perimeter of rectangle given as P = 2 × Length + 2 × Width

I.e P = 2 L + 2 W

Or, 2 L = P - 2 W

∴ L = $\frac{P - 2W}{2}$

Hence The formula to determine the length of rectangle with perimeter and width is L = $\frac{P - 2W}{2}$ Answer

Help me with khan geometry. (Explain or give answer no link to answer thx)

NikAS [45]

Answer:

$\boxed{\sf 200\pi}$

Step-by-step explanation:

We know that the volume of a cone:-

$\boxed{\sf \pi r^2\cfrac{h}{3}}$

(r = 10) (h = 6)

$\sf \pi \times 10^2\times\cfrac{6}{3}$

<u>Divide numbers:-</u>

$\sf \cfrac{6}{3}=\boxed{2}$

$\sf 10^2\times \:2\pi$

$\sf 100\times \:2\pi$

<u>Multiply numbers:-</u>

$\boxed{\sf 200\pi}$

Therefore, your answer is 200π³

We could also multiply 200 by 3.14 which will give you 628 units³.

roger goes shopping and buys an $112 item but has 30% off coupon. if tax is 7%, how much will roger pay altogether?

Yakvenalex [24]

Step-by-step explanation:

Cost = $112

30% discount coupon on the item he's going to buy

=$112 × 30/100 (or you can write 30%)

=$168/5 ($33.6)

7% tax on the item=$112 × 7/100(or you can write 7%)

= $196/25 ($7.84)

Total amount altogether=$112 - $33.6 - $7.84

=$70.56

not sure for the answer^^

£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
