Select the three ratios that represent the number of red cars to blue cars

Laura sees a horse pulling a buggy. She wonders how it can accelerate if the action of the horse pulling the cart would causes a

KatRina [158]

Answer:

The net forces exerted on the horse and cart are not the same, so they are not balanced forces.

Step-by-step explanation:

Please see the Newton's 2nd Law which states that an object accelerates if there is a net or unbalanced force on it. In this scenario there is just one force exerted on the wagon i.e: the force that the horse exerts on it. The wagon accelerates because the horse pulls on it. And the amount of acceleration equals the net force on the wagon divided by its mass.

As there are two forces the push and pull the horse; the wagon pulls the horse backwards, and the ground pushes the horse forward. The net force is determined by the relative sizes of these two forces.

If the ground pushes harder on the horse than the wagon pulls, there is a net force in the forward direction, and the horse accelerates forward, and if the wagon pulls harder on the horse than the ground pushes, there is a net force in the backward direction, and the horse accelerates backward.

If the force that the wagon exerts on the horse is the same size as the force that the ground exerts, the net force on the horse is zero, and the horse does not accelerate.

A theater company charges $10.50 per ticket for people of all age groups. If c represents the total number of children who bough

statuscvo [17]

The equation t = 10.5(c + a) represents the total money earned by the company from the sale of tickets

Solution:

Given that,

Ticket charged for people of all age groups = $ 10.50 per ticket

Let "c" represents the total number of children who bought tickets

Let "a" represents the total number of adults who bought tickets

Now, let the total money collect be represented by "t"

Number of people bought tickets = number of children bought tickets + number of adults bought tickets

Now the total money earned by company is given as:

Total money earned = cost per ticket x number of people bought tickets

Total money collected = cost per ticket x (number of children bought tickets + number of adults bought tickets)

Substituting the known values we get,

$\mathrm{t}=10.5 \times(\mathrm{c}+\mathrm{a})$

t = 10.5(c + a)

Hence, the required equation is t = 10.5(c + a)

Calculate the perimeter of a triangle whose dimensions are 1m 60cm, 1m 80cm and 2m.

Tatiana [17]

★ AnsWer :

➨ 540 cm

★ Step by step Explaination :

Let triangle be ABC,

1m = 100 cm

$\begin{lgathered}\bullet\:\:\textsf{AB = 1m 60cm = \textbf{160 cm}}\\\bullet\:\:\textsf{BC = 1m 80cm = \textbf{180 cm}}\\\bullet\:\:\textsf{CA = 2m = \textbf{200 cm}}\end{lgathered}$

$\setlength{\unitlength}{1.5cm}\begin{picture}(6,8)\linethickness{0.5mm}\qbezier(1,.5)(2,1)(4,2)\qbezier(4,2)(2,3)(2,3)\qbezier(2,3)(2,3)(1,0.5)\put(.7, .3){$C$}\put(4.05, 1.9){$B$}\put(1.7, 2.95){$A$}\put(3.2, 2.5){\sf{160 cm}}\put(0.7,1.7){\sf{200 cm}}\put(2.7, 1.05){\sf{180 cm}}\end{picture}$

$\rule{130}1$

$\underline{ \large \purple{ \mathscr{\dag\:A \bf{ccording} \: to \: \mathscr {Q} \bf{uestion} ....}}}$

$\begin{lgathered}\dashrightarrow\tt\:\: Perimeter_{{\tiny\triangle ABC}}=Sum\:of\:all\:sides\\\\\\\dashrightarrow\tt\:\: Perimeter_{{\tiny\triangle ABC}} = AB + BC + CA\\\\\\\dashrightarrow\tt\:\: Perimeter_{{\tiny\triangle ABC}} = 160 + 180 + 200\\\\\\\dashrightarrow\:\:\underline{\boxed{\tt Perimeter_{{\tiny\triangle ABC}} = 540 \:cm}}\end{lgathered}$

$\therefore\:\underline{\textsf{Perimeter of triangle ABC is \textbf{540 cm}}}.$
