Answer: hi your question is incomplete here is the complete question and the diagram attached

A bicycle chain is pulled tightly so that mn is a common tangent of the gears?

find the distance between the centers of the gear

Answer : 17.8 inches

Explanation:

Applying Pythagorean theorem

considering MN a tangent we will have to find x from the schematic diagram attached

H = 4.3 - 1.8 = 2.5

$x^{2} = MN^{2} + H^{2}$

= $17.6^{2} + 2.5^{2}$

therefore X ( distance between center of gears ) = $\sqrt{17.6^{2} + 2.5^{2} }$ ≈ 17.8 inches

attached to this solution is a free hand diagram of the bicycle chain illustration

Question: The question is incomplete. The bicycle chain diagram wasn't attached to your question. Find attached of the diagram and the answer.

A bicycle chain is pulled tightly so that mn is a common tangent of the gears. Find the distance between the centers of the gears.

Answer: The distance between the centers of the gears is 17.8 in

Explanation:

From the attached file, using Pythagoras theorem to find the value of x, we have;

h = 4.3 - 1.8

= 2.5

x² = MN² + h²

x² = 17.6² +2.5²

x² = 309.76 + 6.25

x² = 316.01

x = √316.01

x = 17.8

Therefore, the distance between the centre of the gear is 17.8 in

In Country C, the unemployment rate among construction workers dropped from 16 percent on September 1, 1992, to 9 percent on Sep

tekilochka [14]

Answer:

(B) 30% decrease

Explanation:

We proceed with the calculation as follows:

For September 1, 1992

For simplicity purpose, let us assume the total number of construction workers in 1992 is 100.

Since, construction workers’ unemployment rate in 1992 = 16%

Therefore;

Number of unemployed construction workers in 1992 = 16

For September 1, 1996

Since the number of construction workers was 20 percent greater on September 1, 1996, than on September 1, 1992, we have:

Total number of construction workers in 1996 = 100 × (1 + 0.2) = 120

Since, construction workers’ unemployment rate in 1996 = 9%

Therefore;

Number of unemployed construction workers in 1996 = 120 × 9% = 10.8

Calculation of change in the number of unemployed construction workers between September 1, 1992 and September 1, 1996

Change in number of unemployed construction workers = 10.8 - 16 = – 5.2

This implies a decrease of 5.2. This will be used is absolute term to calculate the percentage as follows:

Percentage of Change number of unemployed construction workers = (5.2 ÷ 16) × 100 = 32.5% decrease

Since 32.5% is approximately 30% which is the closest in the question, the approximate percentage change in the number of unemployed construction workers between September 1, 1992 and September 1, 1996 is therefore a 30% decrease.

Note:

In real life, there cannot be 10.8 or 5.2 unemployed construction workers. We just used the figures as a hypothetical example without rounding to get for simplicity purpose.
