Answer:
The triangle should be 16 inches wide.
Step-by-step explanation:
What we know:
- One of the legs measures 12 inches.
- The hypotenuse is 20 inches.
We need to solve for b. Solving for a while b is 12 would also be acceptable.
We will use the first equation.
The triangle should be 16 inches wide.
The model Hunter uses makes the division possible given that each
number of digits in a place value are represented by a cube.
- The number of hundredth in each division group is <u>D. 9</u>
Reasons:
The model Hunter started to show the problem is as follows;
Number of 10 by 10 flat = 1
Number of rods of 10 cubes = 4
Number of single cubes = 5
The division is 1.45 ÷ 5, which can be expressed as follows;
Given that the 5 cubes represent the .05 in 1.45, we have;
1 cube = 0.01
Dividing each of the set by 5 gives, for each of the division group;
10 by 10 flat ÷ 5 = 10 × 2 flat = 20 cubes = 20 × 0.01 = 0.2
4 rods × 10 cubes ÷ 5 = 40 cubes ÷ 5 = 8 cubes = 8 × 0.01 = 0.08
5 cubes ÷ 5 = 1 cube = 1 × 0.01 = 0.01
Therefore, each of the division group is 0.2 + 0.08 + 0.01 = 0.29
<em>The </em><em>tenths </em><em>are the </em><em>digits </em><em>after the </em><em>decimal point </em><em>to the </em><em>right</em><em>.</em>
<em />
The hundredths are the digits in the second position after the decimal point to the right.
<em>The </em><em>number </em><em>of </em><em>tenths</em><em> in each group, </em><em>(0.2)</em><em> = 2</em>
<em>There are 2 tenths in each group</em>
The number of hundredths in each group, (0.09) = 9
There are 9 hundredths in each group.
Therefore;
The correct response to the question on how many hundredths would be there in each of the division groups is <u>D. 9</u>
