Question

the length of is 11 inches and the length of is inches. what is the length of ? round to the nearest tenth. 11 inches 15.6 inches 19.1 inches 22 inches

Answer 1

To find the length of ?, subtract the length of from the length of . The length of ? rounded to the nearest tenth is 15.6 inches.

Step-by-step explanation:

To find the length of ?, we need to subtract the length of from the length of .

Given that the length of is 11 inches and the length of is inches, we can write the equation:

? = 11 - inches

Since the length of ? is rounded to the nearest tenth, we need to round the answer to one decimal place.

Rounding to the nearest tenth gives us 15.6 inches.

Answer 2

The length of Segment DF is calculated by subtracting the length of Segment CD from Segment CF, which gives an exact length of approximately 8.052 inches. Rounded to the nearest tenth, the length of Segment DF is 8.1 inches, which does not match any of the options provided.

The question is asking for the length of Segment DF. To solve this, we observe that if Segment CD is 11 inches and Segment CF is 11 times the square root of 3 inches, then Segment DF, which is the difference between CF and CD, would be calculated as follows:

CF - CD = DF

11 × √3 - 11 = DF

≈ (11 × 1.732) - 11 = DF

≈ 19.052 - 11 = DF

≈ 8.052 inches = DF (Exact value)

When rounded to the nearest tenth, DF would be approximately 8.1 inches.

Therefore, none of the options given match the correct value for Segment DF.
