Answer:
12 cm
Step-by-step explanation:
This is a proportionality/similarity problem.
10 cm turned to 4 cm. So by how much has it decreased? In other words, <em>10 multiplied by </em><em>WHAT</em><em> is 4?</em>
0.4 is also known as the scale factor from the large diagram to the small diagram.
So how much would 30 cm become?<em> It would be 30 multiplied by the scale factor, which is </em><em>0.4</em><em>.</em>
<u>Hence, the length of the reduced diagram would be </u><u>12 cm</u><u>.</u>
Answer/Step-by-step explanation:
Given:
86.32947
Let's find the place value of each digit
8 => tens which is 80
6 => unit which is 6
3 => tenth which is 0.3
2 => hundredth which is 0.02
9 => thousandth which is 0.009
4 => ten-thousandths which is 0.0004
7 => hundred-thousandth which is 0.00007
If you add all of the it will give you 86.32947
Thus:
1. 6 => b
2. 8 => g
3. 4 => e
4. 7 => d (there's a mistake in the number of zeros written.)
5. 9 => c
Since it takes her 2 1/2 miles to get to the aquarium from her hotel, you need to subtract the various distances from this value in order to find how long it took Clara to walk the rest of the way to the aquarium.
2 1/2 - (1/4+1 3/4)= 2 1/2 - 2= 1/2
Clara must walk 1/2 a mile to get the rest of the way to the aquarium.
