4 1/5 ÷ 2 1/3 would turn into 21/5 × 7/3 and that would equal 147/15 that would simplify to 49/5 which would simplify to 9 4/5

The area of a trapezium shaped field is 480m the distance between two parlel sides is 15m and one of the parrellel side is 20m f

Annette [7]

The other parallel side is 44 m

Step-by-step explanation:

Let us revise the formula of the area of a trapezium

$A=\frac{1}{2}(b_{1}+b_{2})h$ , where

$b_{1}$ and $b_{2}$ are its parallel bases
h is its height (The distance between the two parallel bases)

∵ The area of a trapezium is shaped field is 480 m²

∴ A = 480 m²

∵ The distance between two parallel sides is 15 m

∴ h = 15 m

∵ One of the parallel side is 20 m

∴ $b_{1}$ = 20 m

We need to find $b_{2}$

Substitute all these value in the rule of the area below

∵ $A=\frac{1}{2}(b_{1}+b_{2})h$

∴ $480=\frac{1}{2}(20+b_{2})(15)$

- Multiply the two sides by 2

∴ $960=(20+b_{2})(15)$

- Divide both sides by 15

∴ $64=20+b_{2}$

- Subtract 20 from both sides

∴ $44=b_{2}$

The other parallel side is 44 m

A jacket is on sale for 40% off .The sale price is $90.00.What is the original amount of the jacket

34kurt

Set up a proportion
90/x = 60/100
60x = 9000
x = 150

if you're wondering why I used 60 instead of 40 in the proportion it is because $90 is 60% of the original price, not 40%

hope this helps!
