Step-by-step explanation:

The total number of parts is 4 + 1 + 2 = 7.

Nickel is 4/7 of the mass: 4/7 × 35 kg = 20 kg.

Zinc is 1/7 of the mass: 1/7 × 35 kg = 5 kg.

Copper is 2/7 of the mass: 2/7 × 35 = 10 kg.

What is the product of 16x48?
Elis [28]
768 because 6x8 = 48 the 8 drop Down to the answer and the 4 on top of 1 and multiply 1x8= 8+1 =9 so the 9 drop down to the answer. Now that is fake because you need to multiply 4x6 and 4x1 so 4x6 is 24 below the 8 add a 0 and go 1 move to the left and put 4 and 2 on top of 1 now 4x1 is 4+1 is 5 and put 5 on the left of 4 and the final step is add 98+540=768 so 768 is your real answer.

Please help to prove parallelogram.​
tino4ka555 [31]

The question requests proof that WV = VR. See the definition of Mathematical proof and the explanation for the proof below.

<h3>What is a mathematical proof?</h3>

Mathematical proof refers to the steps of logical arguments which are given to show that a mathematical statement is true or correct.

<h3>What is the proof that WV = VR?</h3>

  • Note that SR ║ QT;

Reason: This is given. The image is a parallelogram.

  • Hence, ∠PSR  = ∠WVP
    Reason: Alternate angles formed by two parallel lines crossing each other
Hence, SV = PVReason: This is given by the annotation on the image
  • Therefore: ΔSVR ≅ PVW
  • Reason: They are formed by two parallel lines crossing each other.

Therefore if  ΔSVR ≅ PVW;

Then WV = VR.
