The 4 in 40 is in the tens place and the 4 in 400 is in the hundreds place so 40 will be less than 400.
Answer:
B. 1,440
Step-by-step explanation:
Square units are the units of measuring area. Therefore, this question asks for the area of the room.
The room has the shape of a rectangle with:
length = 13 units and width = 9 units
The are of the rectangle can be calculated using the following rule:
area of rectangle = length * width
area of the room = 13 * 9 = 117 square units
First, form an equation.
The equation -
= ⅛(23+17)
= ⅛ × 40
= 40/8
= 5
29/9 kilograms because 7/3 is equivalent to 21/9 and then 21/9+8/9 = 29/9
