Answer:

46 lb = 20.91 kg = 20,910 g

Step-by-step explanation:

To convert 46 lb to kg and then to g

Step 1

Establish the conversion from pounds to kilograms.

2.2 lb = 1 kg

Step 2

Then, use simple relating mathematically to use the conversion rate to convert 46 lb

2.2 lb = 1 kg

46 lb = (46×1/2.2) = 20.90909 = 20.91 kg

Step 3

To convert to grams, we repeat step 1 and 2 again.

1 kg = 1000 g

20.91 kg = (20.91×1000/1) = 20910 g

Hope this Helps!!!

Answer:

First, you would cancel out the lb in 2.2 lb, and cancel the kg in 1 kg. Then, you cross multiply. 46 x 1 x 1000 is 46000, you're just moving the decimal point. 1 x 2.2 x 1 would stay the same, so you would have 46000 over 2.2.

Step-by-step explanation:

The figures below are based on semicircles and squares. Find the perimeter and the area of each shape. Give your answer as a com
irina1246 [14]

Answer:

Part 1) The area of the figure is A=48\ cm^2

Part 2) The perimeter of the figure is P=4(2+3\pi)\ cm

Step-by-step explanation:

Part 1) Find the area of the figure

we know that

The area of the figure is equal to the area of three squares

so

A=3[4^2]=48\ cm^2

Part 2) Find the perimeter of the figure

we know that

The perimeter of the figure is equal to two times the length side of the square, plus the circumference of six semicircles ( or the circumference of three circles)

Remember that

The circumference of a circle is equal to

C=\pi D

where

D is the diameter of the circle

In this problem

D=4\ cm

so

P=2(4)+3[\pi(4)]=(8+12\pi)\ cm

simplify

P=4(2+3\pi)\ cm

What is x+y=8 and 5x+3y=34 graphed on the same graph
expeople1 [14]
To help you graph this, get y alone in both equations. If you don't have a graphing calculator, use the Desmos graphing calculator online.

So, you will end up graphing this:
y=8-x
y=(34/3)-(5/3)x

They will meet at (5,3)

Eva has £6.05 in her moneybox.
PIT_PIT [208]

Answer:

11 of 20p, 22 of 10p and 33 of 5p

Step-by-step explanation:

Eva has 20p, 10p and 5p coins, total of £6.05 = 605p

Let 20p=x, 10p=y, 5p=z

<u>Then</u>:

  • 20x + 10y + 5z = 605
  • y : x = 2 : 1 ⇒ x= y/2
  • y : z = 2 : 3 ⇒ z= 3y/2

<u>Rewriting the first equation considering next two:</u>

  • 10y + 10y + 7.5y = 605
  • 27.5y = 605
  • y= 605/27.5
  • y= 22
  • x= y/2 = 22/2 = 11
  • z = 3y/2 = 3*11 = 33

<u>Answer:</u> 11 of 20p coins, 22 of 10p coins and 33 of 5p coins
