Assume that you don’t know any kind of longhand method of division. Explain how you can use reasoning to calculate 495 ÷ 35

alexira [117]

To divide one number by another is to determine how many times the second number is contained in the first.So let's count how many times 35 can fit in 495. Decompose the number 495 on the amount of my preferred numbers.350 this 10 times for 35105 is a 3 for 35that is, 13 times already fit. 350+105=455.
Try to add the 14th time.455+35=490. Is extra 5.
Then, 495:35=14 and 5/35 =14 1/7

A cube with a volume of 75 cmis dilated by a factor of 5.

Rashid [163]

The volume of the dilated cube is $9375 \ {cm}^{3}$

Explanation:

The volume of the cube is $75 \ {cm}^{3}$

It is given that the cube is dilated by a factor of 5.

We need to determine the volume of the dilated cube.

Since, we know that the dilation is a transformation that changes the size of the image but not the shape.

Since, it is given that the volume of the cube is dilated by a factor of 5, the length of the image will be 5 times greater, the width of the image will be 5 times greater and the height of the image will be times greater than the original image.

Thus, the volume of the dilated cube is given by,

$Volume = (5\times5\times5)(volume \ of \ the \ original \ cube)$
