shari has 1 1/2 gallons of orange juice. She wants to serve the orange juice equally among her 12 friends. How many ounces of juice will each friend receive

Answers

So there are 128 ounces in a gallon.
So half a gallon would have 64 ounces
Now it says Shari has 1 1/2 which means we would add 128 ounces and 64 ounces together to get 192 ounces.
1 1/2 gallons = 192 ounces
Now we take the 192 ounces and divide it into 12 because she has 12 friends to share with.

Four congruent isosceles right triangles are cut from the 4 corners of a square with a side of 20 units. The length of one leg of the triangles is equal to 4 units. What is the area of the remaining octagon?

Answers

Answer:

368 sq. units.

Step-by-step explanation:

We have a square of side lengths 20 units and we cut four congruent isosceles right triangles from the corners of the square.

Now, the four isosceles right triangles have one leg equal to 4 units.  

Therefore, the area of four triangles = 4 * ( (1)/(2) * 4 * 4) = 32 sq. units.

Now, we have the area of the given square is (20 × 20) = 400 sq. units.

Therefore, the area of the remaining octagon will be (400 - 32) = 368 sq. units. (Answer)
