Answer:

52.5 ft.

Step-by-step explanation:

To find the area of a triangle you find the hight and length and multiply them which in this case would be 84. Then, you divide it by two because a triangle is half of a square which would equal 42. Lastly, you do the same with the left side of the triangle which would equal 10.5. then, you add 42 and 10.5 together and your answer is 52.5.

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.

What is the area of the triangle? 5 in. 3 in 4in O 6 square inches O 7-square inches O 10 square inches O 12 square ches

WARRIOR [948]

Answer:

-------------------Heya Kjowanpreet!--------------

$\large{ \tt{ \star\: S \: O \: L \: U \: T \: I \: O \: N : }}$

GiveN :

Sides of the triangle : 3 in , 5 in and 4 ft

To FinD :

Area of the provided right angled triangle

FormulA :

Area of right angled triangle = 1/2 b × p where b = base & p = perpendicular. Here , Perpendicular = 3 in and base = 4 in

SolvinG :

$\large{ \boxed{ \bf{Area \: of \:right \: angled \: triangle : \frac{1}{2} b \times p }}}$

$\longrightarrow{ \tt{} \frac{1}{2} \times 3 \times 4}$

$\longrightarrow{ \boxed{ \tt{6 \: in ^{2} }}}$

Yay ! Finally , We solved. Our final answer is 6 square inches.

What are the possible numbers of positive, negative, and complex zeros of f(x) = −x6 − x5 − x4 − 4x3 − 12x2 + 12?

ad-work [718]

$f(x) = -x^6 -x^5 - x^4 - 4x^3 - 12x^2 + 12$

There is only one change of sign, so there is only one possible positive root.

$f(-x) = -(-x)^6 -(-x)^5 - (-x)^4 - 4(-x)^3 - 12(-x)^2 + 12\\
f(-x) = -x^6 +x^5 - x^4 + 4x^3 - 12x^2 + 12$

There are five changes of signs, so there are 5,3 or 1 possible negative roots.

The number of complex roots can be equal to 4,2 or 0 (degree of a polynomial - possible positive roots - possible negative roots)
