What’s the total height of a 17-story building that measures 4 meters 2 decimeters 17 centimeters per story?

The answer is:

The total height of the 17-story building is 74.29 meters.

This a unit convertion problem. We know that there is a 17-story building and the height of each story, we need to convert the units and then, calculate the total height.

We need to use the following convertion factors:

Now, converting the given units we have:

Meters to centimeters:

Decimeters to centimeters:

So, we know that one story measures 4 meters, 2 decimeters (dm) and 17 centimeters (cm), and if we want to calculate the total height of the 17-story building, we need to use the following equation:

Now,

Converting from centimeters to meters, we have:

Hence, we have that the total height of the 17-story building is 74.29 meters.

Have a nice day!

h = 74.29 meters

Step-by-step explanation:

We know that a decimeter is equal to 10 cm.

and 100 cm equals 1 meter,

Then, each floor measures 4 meters + 2 decimetres + and 17 centimeters

This is:

4m + 20cm + 17cm

= 4m + 37cm

= 4m + 0.37 m

= 4.37 m.

If the building has 17 floors then its height is:

h = 74.29 meters

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
