Hi, What is the lowest positive integer greater than 1, which when divided by 5 or 8 leaves a remainder of 1
ludmilkaskok [199]
Very interesting question!

Let's try to get something that would work for just 5 for now.
Any of these numbers would leave a remainder of 1 when divided by just 5:
6, 11, 16, 21, 26, 31, 36, 41, 46, 51, 56, 61, 66, 71, 76, 81, 86, ...
Notice that they all look like 5*(something) + 1. Basically, they are all multiples of 5 plus 1.

Let's see what would work for just 8:
9, 17, 25, 33, 41, 49, 57, 65, 73, 81, 89, ...

Are there any matches... AHA! It's 81. This is the lowest positive integer greater than 1 that follows the rule for both 5 and 8.

Two rubix cubes are shown in the image. The edge length of these cubes is 5.7 centimeters. What is the combined volume of the tw
Bad White [126]

Answer:

The answer is No.4

Step-by-step explanation:

Giventhat the formula of a cube is, V = x³ where x determine the length of the edge of the cube. By using this formula, you may find out the volume of a rubix cube :

x = 5.7cm

V = 5.7³

= 185.193cm³

The question ask us to find the volume of 2 combined cubes so, we can just multiply it by 2 :

V = 185.193 × 2

= 370.386cm³

Given:

Distance already covered = 3.5 miles

100 miles covered in 2 hour

FInd;

Equation of given scenario

Computation:

Assume;

Total miles covered = y

Total number of hours = x

Speed of car = 100 / 2

Speed of car = 50 miles per hour

Total miles covered = Distance already covered + [Speed of car][Total number of hours]

y = 3.5 + [50][x]

y = 50x + 3.5
