The Mackinac Bridge in Michigan is the third-longest suspension bridge in the United States.
a. How high above the water is the roadway in meters? Round to the nearest hundredth.
The roadway is about ____ meters above the water.
Question 2
b. The bridge has a length of 26,372 feet. What is the length in kilometers? Round to the nearest hundredth.
The length of the bridge is about ____ kilometers.
The roadway is about 60.66 meters above the water.
The length of the bridge is about 8.04 kilometers.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 hour = 60 minutes
1 km = 1000 m
We have,
The length of the roadway above the water = 199 ft
1 ft = 0.3048 m
Multiply 199 on both sides.
199 ft = 60.66 m
The bridge has a length of 26,372 feet.
1 ft = 0.0003048
Multiply 26372 on both sides.
26372 ft = 26372 x 0.0003048
26372 ft = 8.04 km
Thus,
The roadway in meters is about 60.66 meters above the water.
The length of the bridge in km is about 8.04 kilometers.

"Raul’s grandfather is Miguel, and Raul’s sister is Paula. Raul’s age is the same as his grandfather’s age minus 60 times the age of his sister. Miguel is 65 years old. Using the results from Part C, write an equation to find Paula’s age, p (in years)." answer: "r = 65 - 60p"
"Rewrite the equation from Part D by factoring the side that contains the variable p." answer: "r = 5 (13 - 12p)"
"Solve the equation for p to find Paula’s age. Express her age (in years) as a fraction." "answer: p = -1/60r + 12/12"

Challenge in a company, 65% of the workers are women. If 1,435 people work for the company
who aren't women, how many workers are there in all?
Use pencil and paper. Show two different
ways that you can solve this problem.
There are workers in all. (Type a whole number.)
Answer:
You have 1,435 people in total so you take that number and multiply it by .45 cause there’s 45% male workers and you convert it to a decimal so you can multiply there are 645 male workers since you can’t have 3/4 a human
Step-by-step explanation:
1435 x .45 =645.75

Step-by-step explanation: 1.68x + 24.288x²A computer store buys a computer system at a cost of 463.20$. The selling price was first at $772, but then the store advertised 40% a markdown on the system.Find the current sale price.
The current sale price is if A computer store buys a computer system at a cost of $463.20. The selling price was first at $772, but then the store advertised a 40% markdown on the system is $463.2.
What is the selling price?The amount a buyer pays for a good or service is known as the selling price. It may differ based on the price that buyers are prepared to pay, the seller's acceptance threshold, and how competitive the price is in relation to those of other companies in the market.
Given:
The cost price = $463.20,
The initial selling price = $772,
We know that Markdown= Selling price × markdown rate
Markdown = 772 × 40%
Markdown = 772 × 0.4
Markdown = $308.8
So new selling price = The initial selling price - markdown price
Current selling price = 772 - 308.8
Current selling price = $463.2
Therefore, the current sale price is if A computer store buys a computer system at a cost of $463.20. The selling price was first at $772, but then the store advertised a 40% markdown on the system is $463.2.
