Say you have 100 cats and dogs well 70 of them are dog and 30 are cats. out of the 70 dogs 50 drink water and the other 20 eat food but the 30 cats took half of the dogs food and water so you would divide 2 into the 50 to get how much water the cats took of food and you would divide 2 into the 20 to get what the cats took of food from the dogs. so it would be 50/2=25 water and 20/2=10 food and then add those two numbers together to get 35

Let the cost of the hair dryer equal x.

The net cost plus a 40% markup equals 42, set up an equation and solve forex.

1.4x = 42

Divide both sides by 1.4

X = 42 / 1.4

X = 30

The net cost was £30

At the park there is a pool shaped like a circle. A ring-shaped path goes around the pool. Its inner diameter is 22yd and its ou

First, we need to think about what we're actually solving for: the area of the path. To find this, we can find the area of the whole thing, minus the area of the pool.

The diagram would look something like the picture I attached. We know that to find the area of a circle, you do πr^2. The radius is half of the diameter, so halve the diameters:

22/2 = 11 yards
32/2 = 16 yards

Then solve for the area of both circles.
π $11^{2}$ $= 121$ π ≈ 380.13 (area of the pool)
π $16^{2}$ $= 256$ π ≈ 804.25 (area of the whole thing)

Next, subtract the area of the pool from the area of the whole thing to find the area of the walkway:
$804.25 - 380.13 = 424.12$ (area of the walkway)

Finally, divide the area of the walkway by 6 to see how many gallons of paint you'll need:

424.12 ÷ 6 ≈ 70.69

So you'll need 71 gallons of paint!

Hope I helped and let me know if you have any questions :)
