The Table Below Gives The Dimensions Of A Bridge And A Scale Model Of The Bridge.Find The Scale Factor

Answers

Answer 1

Answer:

Scale factor = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Formula for the scale factor is,

Scale factor = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the original}}[/tex]

                    = [tex]\frac{\text{Dimension of the model}}{\text{Dimension of the bridge}}[/tex]

                    = [tex]\frac{\text{Width of the model}}{\text{Width of the bridge}}[/tex]

                    = [tex]\frac{7}{35}[/tex]

                    = [tex]\frac{1}{5}[/tex]

Therefore, scale factor of the model to the real bridge = [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

∵ circumference of circle = 2πr = m

∴ r = m/2π

∵ area of circle = πr²

∴ area of circle = (m/2π)² × π = m²/2π² × π = m²/2π

A farmhouse shelters 16 animals, some are pigs, and some are ducks. Altogether there are 42 legs. How many pigs are there?

Answers

Answer:

5 pigs

Step-by-step explanation:

A farmhouse shelters 16 animals, some are pigs, and some are ducks. Altogether there are 42 legs. How many pigs are there?

Let us represent:

Number of pigs = x

Number of ducks = y

Our system of equations is given as:

A farmhouse shelters 16 animals, some are pigs, and some are ducks.

x + y = 16...... Equation 1

x = 16 - y

Altogether there are 42 legs.

Ducks have 2 legs(feet) , pigs have 4 legs,

4x + 2y = 42..... Equation 2

We substitute

16 - y for x in Equation 2

Hence:

4(16 - y) + 2y = 42

64 - 4y + 2y = 42

Collect like terms

- 4y + 2y = 42 - 64

-2y =- 22

y = -22/-2

y = 11 ducks

Solving for x.

x = 16 - y

x = 16 - 11

x = 5 pigs

Therefore, we have 5 pigs

What is the coefficient in the expression 4x + 2
O2
O4
Ox
O+​

Answers

A coefficient is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x).

The 2 and + are out since they don't have variables(and the + is just a +).

So 4 and x are left. x is a variable, not a coefficient, so the last(and correct) answer is 4.
