Answer:1490
Step-by-step explanation:so while solving this question, you want to make sure the decimals are on top of each other. 8+8 is 16 so you write 6 and carry 1. 4+9 is 13 +1 =14, write 4 carry one across the decimals. 5+4 is 9 plus 1 equals 10 write zero carry 1. 7+1 is 8 plus 1 is 9 so you write that down and since 1 and 4 have no numbers under them, you write it down too giving you 1490.46

Answer:
a) 1.8
b) 3.6
Step-by-step explanation:
Conversion and calculation of areas
The area of a rectangle is A=wh, where w is the width and h is the height. There are 3 feet in one yard
a)
We are told Kalie put 6 stickers, each one of 1/2 centimeters (0.5 cm) wide by 3/5 (0.6 cm) centimeter long. The area of one sticker is
A=(0.5)(0.6)=0.3
Assuming there is no overlapping, the 6 stickers have a total area
6*0.3 =1.8
b)
Each of Elana's wrapping papers measures 2/5 yards long and 1/4 yard wide. Converting them to feet we have
long=2/5*3=1.2 feet
wide=1/4*3=0.75 feet
Area of each paper=1.2 feet*0.75 feet=0.9
Area of the entire board, assuming no overlapping and no space left uncovered=4*0.9
Area of board=3.6
