Answer:

1.1 or 11/10

Step-by-step explanation:

\frac{3}{5} +\frac{5}{10}

We can "lengthen" 3/5 by multiplying both the top and bottom number with 2.

It'll still be the same fraction, but we'll get 10 at the bottom.

\frac{3}{5} =\frac{3*2}{5*2}=\frac{6}{10}

This gives us 10 at the bottom, which means we can now add it to 5/10.

\frac{6}{10} +\frac{5}{10}=\frac{11}{10}=1.1

Answer: 1.1 or 11/10

The mean length of 7 planks of wood is 1.35m. When an extra plank of wood is added, the mean length of a plank of wood increase
azamat

Answer: Hello There!................

Mean = Sum of observation / total number of observation

Mean = 1.35m

1.35  = Sum of length of 7 wood planks/ 7

1.35*7 = Sum of the length of 7 wood planks

9.45 = Sum of the length of 7 wood planks

Let the length of extra added wood plank = x

So,

(Sum of the length of 7 wood planks + x) / 8 = 1.4m

(9.45 + x) / 8 = 1.4

9.45 + x = 1.4 * 8

9.45 + x = 11.2

x = 11.2- 9.45

= 1.75

So,

The length of extra added wood plank = 1.75m

Find the perimeter of the figure to the nearest hundredth. Sorry to ask ANOTHER question on this stuff but I'm doing an assignme
WARRIOR [948]

Answer:

I did my best, but it has been a while. I really hope that this helps

Step-by-step explanation:

so you can find the perimeter of a circle

-----The perimeter of a circle is π × d where d is the diameter so half of that is 1/2 π × d. But If you are going to walk around a semicircle, you need to go halfway around the circle and then across a diagonal to get back to where you started, so the perimeter is 1/2 π × d + d.
