Answer:
Option D
Step-by-step explanation:
If the whole grid is considered to be 1,
Each small grid will value = 
There are 72 shaded grids which represent the hundreds = 0.72
When these grids have been divided into 9 equal rows, number of grids in each row = 8
And the value of 8 grids in each row = 0.01 × 8 = 0.08
So the equation is,
0.72 ÷ 9 = 0.08
Therefore, equation represented by the model will be Option (D).
Answer:
a would be correct
Step-by-step explanation:
Answer:
The width of the door is 32 cm.
Explanation:
The formula for area is A = l*w
so the equation becomes:
1792 = 56*w
Divide both sides by 56 and you get
w = 32
6. vertical
7. LSM and MSN are vertical angles
8. MSN
Change each fraction into decimal.
1/4 = 0.25
1/6 = 0.166 (countinuing)
0.25 is greater than 0.17 (rounded) by 0.08
1/4 is your answer
hope this helps
