Answer: About 1 yard is a reasonable estimate.
Step-by-step explanation:
1 ⁷/₁₄ is a yard and a half
⁹/₁₄ is just a bit more than half a yard
Rounding that off to half a yard, and finding the difference leaves about 1 yard.
The actual difference is ¹²/₁₄ of a yard the same as ⁶/₇ of a yard, or just about 5¹/₂ inches less than a yard.

Answer:
- sin(θ) = (9√97)/97
- cos(θ) = (-4√97)/97
- csc(θ) = (√97)/9
- sec(θ) = (-√97)/4
- cot(θ) = -4/9
Step-by-step explanation:
The angle is in the 2nd quadrant, where the sine is positive and the cosine is negative.
tan^2(θ) +1 = sec^2(θ) = (-9/4)^2 +1 = 97/16 ⇒ sec = -(1/4)√97
cot(θ) = 1/tan(θ) = -4/9
csc^2(θ) = cot^2(θ) +1 = (-4/9)^2 +1 = 97/81 ⇒ csc = (1/9)√97
sin(θ) = 1/csc(θ) = (9√97)/97
cos(θ) = 1/sec(θ) = (-4√97)/97

Answer:
See below.
Step-by-step explanation:
The question tells us that 2.54 cm is equivalent to 1 inch. The next part wants to know what 5.08 cm is in inches. We can just divide 5.08 by 2.54 to figure that out.
5.08/2.54 = 2
This means that 5.08 cm is 2 inches.
The next one wants to know how many centimeters 10 inches is. We can 2.54 and multiply it by 10.
2.54 · 10 = 25.4
This means that 25.4 cm is 10 inches.
