Pl help.

put \"o\" at center of picture. Imagine u move ZOY and XOY to fill up ZPW and WQX respectively. That will fill up the top half of square. Thus,

1/2 of PZ = 6
PQ = 12

Area = 12*6 = 72

Tan Packs 6kg of peas into 7 packets. Every packet contains an equal amount of peas. What is the maximum amount of peas in each packet? Express your answer as a decimal and round it off to 2 decimal places?


Each packet contains 1.166kg.
so rounding off I get 1.17kg.

But the answer given is 0.86kg. Pl help…I donno…

Is it ok if we do

7*13=91

or

7*12=84
84+31+31=146

can 91 and 146 be right answers for this?

Hi
Q1)

Difference in cost between a plate and a bowl ------ 3

He paid $54 more for the plates.

54/3 ------- 18

Number of plates ------- 18

Jordan bought an equal amt of bowls n plates.

Total number of bowls n plates he bought ------- 18 + 18 ------ 36

Q2)

Usuable area of cardboard ------ 12cm by 12 cm

This 'll give 36 pieces of 2cm by 2cm square.
