Answer:
3.728 cm²
90
Step-by-step explanation:
To built the envelope I am using a rectangular piece of material 28 m long and 12 m wide.
Out of this material, I have to cut patches that are 1/12 the length and 2/15 the width of the whole material.
So, the length of the patches is
m and the width of the patches is
m.
Therefore, the area of the patches is (1.6 × 2.33) = 3.728 m² each. (Answer)
Now, the area of the rectangular piece of material is (28 × 12) = 336 m²
Hence,
≈ 90 such patches can be made out of the whole material. (Answer)

Answer:
-27
Step-by-step explanation:
Any operations inside parentheses must be carried out first.
Thus,
9 ÷ 3[(20 − 7) − 22] becomes 9 ÷ 3[(13) − 22]
This, in turn, becomes 9 ÷ 3[-9].
The negative operator can be taken out and written up front: -9 ÷ 3[9) Note: this does not call for subtraction).
Carrying out the indicated operations from left to right:
-3(9) = -27
