Answer to 5 and 6 please?​
yKpoI14uk [10]

Answer:

5. ST  6. AT

Step-by-step explanation:

For a product to be divisible by a number, one of the factors must be that number. This can be achieved by one of the consecutive numbers being that number, or a multiple of that number.

5. 4 x 5 x 6 = 120 which is divisible by 5

1 x 2 x 3 = 6 which is not divisible by 5

6. 1 x 2 x 3 = 6 which is divisible by 6

2 x 3 x 4 = 24 which is divisible by 6

3 x 4 x 5 = 60 which is divisible by 6

4 x 5 x 6 = 120 which is divisible by 6

And now we will just repeat ourselves.

on a lake, Carol rowed a boat for 1/8 mile. Then luke rowed the boat for 3/8 mile. how far did carol and like row in all? simpli
Semmy [17]

Answer:

Total = \frac{1}{2}

Step-by-step explanation:

Given

Carol = \frac{1}{8}

Luke = \frac{3}{8}

Required

How far did they row together

To do this, we simply add the distance they both covered.

Total = Carol + Luke

This gives;

Total = \frac{1}{8} + \frac{3}{8}

Take LCM

Total = \frac{1+3}{8}

Total = \frac{4}{8}

Simplify

Total = \frac{1}{2}

<em>Hence, they both rowed 1/2 mile</em>

It looks like this is a square pyramid net, and to find the surface area you need to know the base and height. By looking at the image 5 ft is the height and the base is 3 ft.

The surface area of the square pyramid is <u>40.32</u>

hope this helps!

P-6+2&lt;-5 solve each inequality and graph its solution, i am lost
DerKrebs [107]

Answer:

P < -1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

  • P - 6 + 2 < -5
  • P - 4 < -5

Step 2: Add 4 to both sides.

  • P - 4 + 4 < -5 + 4
  • P < -1

Therefore, the answer is P < -1! (Also, the graphed solution is below.)
