Measure of each side of an equilateral triangle is 12cm. It's area is given by
telo118 [61]

Answer:

D

Step-by-step explanation:

The area (A) of an equilateral triangle is calculated as

A = \frac{s^2\sqrt{3} }{4} ← s is length of a side

Here s = 12, thus

A = \frac{12^2\sqrt{3} }{4}

  = \frac{144\sqrt{3} }{4}

  = 36\sqrt{3} → D

A total of 135 seats, 118 front handlebars (that steer the bike) and 269 wheels how many bicycles, tandem bicycles, and tricycle
lesya692 [45]

Answer: There are 35 bicycles, 33 tricycles and 50 tandem bicycles.

Step-by-step explanation:

Since we have given that

Number of seats = 135

Number of front handle bars = 118

Number of wheels = 269

Since there are 118 front handle bars.

And we know that each bicycle has 1 front handle bars.

So, total number of bicycles = 118

Now, each bicycle has 2 wheels

So, Number of wheels should be

118\times 2\\\\=236\ wheels

But here we have 269 wheels , it means it has tricycle which has 3 wheels.

So, Remaining wheels would be

269-236\\\\=33\ wheels

It means 33 bicycles has 3 wheels .

So, Number of tricycles = 33

So, Number of bicycles should be now

118-33=85

Each bicycle has 1 seat

So, number of seats should be 85

But we have 135 seats,

So, remaining seats should be of tandem bicycle.

135-85=50

So, Number of bicycles now becomes

85-50 = 35

Hence, there are 35 bicycles, 33 tricycles and 50 tandem bicycles.
