Answer:

16.93

Step-by-step explanation:

Answer:

Width = 15 ft

Length = 25ft

Step-by-step explanation:

Given that:

Total area = 375 ft²

Length = 10 + width

Let ;

Width = x

Length = x + 10

Area of a rectangle = Length * Width

Area of rectangle = 375 ft²

375 = x * (x + 10)

375 = X² + 10x

x² + 10x - 375 = 0

X² + 25x - 15x - 375 =. 0

x(x + 25) - 15(x + 25) = 0

x +. 25 = 0

x - 15 = 0

Hence,

x = - 25 or x = 15

X cannot be negative

Hence, x = 15

Width = 15 ft

Length = x + 10 = 15 + 10 = 25 ft

Answer: 1200 Joules

Step-by-step explanation:

Given that:

Distance (d) across which bag is dragged = 20 meters

Applied force (F) = 60 N

The workdone is the product of the applied force and the distance through which the force is applied ;

Hence,

Workdone = Force * Distance

Workdone = 60 N * 20 m

Workdone = 1200Nm

OR 1200 Joules

The work done required to drag box is 1200 Joule.

Work done is defined as the energy transfer that occurs when an object is moved over a distance by an external force .

[tex]Workdone=force*displacement+cos\theta[/tex]

Where [tex]\theta[/tex] is angle between direction of force and displacement.

Here given that force F = 60 N and Displacement = 20 meters

Since, Displacement of box is in the direction of force.

Therefore, [tex]\theta=0[/tex] degree.

Substituting all the values.

 [tex]W=60*20*cos0\\\\W=1200*1\\\\W=1200joule[/tex]

Step-by-step explanation:

Lets plug in the numbers for each equations:

1.     4 x 3 + -5 = 7

     and 4 times 3 equals 12. minus 5 is 7.

2.      4^3 is just 64

Answer:

1500 - 30x

Step-by-step explanation:

Aquí, queremos obtener una función que describa la cantidad de litros que quedan en la piscina a las x horas después de abrir la salida de drenaje.

De la pregunta, la capacidad total de la piscina. es de 1.500 litros.

La tasa de goteo es de 0,5 litros por minuto.

x horas es lo mismo que 60 * x = 60x minutos

La cantidad de litros caídos en 60x minutos será 60x * 0,5 litros = 30x litros.

Entonces el número de litros que quedan será; 1500 - 30x

Answer:

5184ft

Step-by-step explanation:

d= distance an object falls when dropped from a tower

t= time it takes to fall

According to the first sentence,

d(sign of proportionality) t^2

Introducing a constant k:

d =kt^2

when d=144ft ,t=3sec

Substitute the values to find k

144 =k(3^2)

144 = 9k

k = 144/9

k =16

Substitute k =16 and t =18sec

d =kt^2

d =16×(18^2)

d =16× 324

d = 5184ft

*** x represents the number of shirts he's buying***

Answer:

Simplifying

-9x + 4 + -12 = 64

Reorder the terms:

4 + -12 + -9x = 64

Combine like terms: 4 + -12 = -8

-8 + -9x = 64

Solving

-8 + -9x = 64

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '8' to each side of the equation.

-8 + 8 + -9x = 64 + 8

Combine like terms: -8 + 8 = 0

0 + -9x = 64 + 8

-9x = 64 + 8

Combine like terms: 64 + 8 = 72

-9x = 72

Divide each side by '-9'.

x = -8

Simplifying

x = -8

Answer:

-8

Step-by-step explanation:

-9x + 4 - 12 = 64

-9x = 64 - 4 + 12

-9x = 72

x = -8

Answer:396  children and 217 adults swam at the pool.

Step-by-step explanation:

Step 1

let Children be represented as  x

and Adults  be represented as y

therefore

Step 2

x + y =  613.........equation 1 -----represents the 613 people (children and adults) that used the public swimming pool.

And

1.75x + 2.00y = 1127... equation 2------represents the daily prices which totaled 1127 dollars

Making x subject formulae in equation 1 and substituting in equation 2

x= 613-y

1.75(613-y) + 2.00y = 1127

1072.75 -1.75y+ 2y=1127

1127-1072.5 = -1.75y +2y

54.25=0.25y

y=54.25/0.25

y=217

Substitute y = 218 in (1)

x + 217= 613

x = 613-217

x = 396

396  children and 217 adults swam at the pool.

Answer: 396 children and 217 adults tickets were sold at the pool.

Step-by-step explanation:

Given data:

Number of people who used the pool = 613

Total sum on the receipt = 1127.

Price of adult tickets = $2

Price for children tickets = 1.75

Solution:

Let

Children = x

Adults = y

x + y = 613......... equation 1

1.75x + 2y = 1127..... equation 2

Multiply equation (1) by 2

2x + 2y = 1226........ equation 3

1.75x + 2y= 1127

Subtract (2) from (3)

0.25x = 99

x = 396

Substitute x = 396 in equation (1)

x + y = 613

396 + y = 613

y = 217

396 children and 217 adults tickets were sold at the pool.

Answer:

4. 3

5. 5

Step-by-step explanation:

Let x = number of blocks in a bag.

4.

Left side = 2 bags & 7 blocks

Right side = 1 bag & 10 blocks

The beam is balanced, so the weights of the two sides are equal.

2x + 7 = x + 10

x = 3

There are 3 blocks in a bag.

5.

Left side = 3 bags & 6 blocks

Right side = 4 bags & 1 block

The beam is balanced, so the weights of the two sides are equal.

3x + 6 = 4x + 1

-x = -5

x = 5

There are 5 blocks in a bag.

Answer: 4. x+3x=x+1x

At that rate, the time taken to finish each lap will be 3.75 minutes each lap. The pair of quantities that form a proportional relationship will be 15: 4.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

Trevor is training for a race. He swims 12 laps in 45 minutes.

At that rate, the time taken to finish each lap will be

⇒ 45 / 12

⇒ 3.75 minutes each lap

At that rate, the time taken to finish each lap will be 3.75 minutes each lap.

The pair of quantities that form a proportional relationship will be 15: 4.
