Answer:
E = 16 ≤ x ≤ 23
Step-by-step explanation:
Number of eggs laid per week = between 18 and 25
Let x = exact number of eggs laid
Using inequality :
18 ≤ x ≤ 25
Number of eggs Pat eats = 2
18 - 2 ≤ x ≤ 25 - 2
Eggs left after pat eats 2 of the eggs :
16 ≤ x ≤ 23
Hence,
Eggs eaten by pat's dogs :
E = 16 ≤ x ≤ 23
A builder wants to create a rectangular room in a house she wants it to have a total area of 375 square feet, and it should be 10 feet longer than it is wide
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

Which pair of quantities form a proportional relationship? Select all that apply
Answer:
Yes
Step-by-step explanation:
First you gotta add the yes, and ten you multiply it by the no so yesXno but then you are left with a negative answer so then you wanna add an extra Yes to even it out and then it becomes YesXno+Yes and then you get your answer which is yes. I learned this from the man down the street that lives near the gas station

What is speed?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

What is the solution: –9x + 4 –12 = 64
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

On a hot summers day, 613 people used the public swimming pool. The daily prices are 1.75 dollars for children and 2 dollars fir adults. The recipts for admission totaled 1127 dollars. How many children and how many adults swam at the public pool that day?
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.

En una piscina hay 1500 litros y el desagüe bota en el despiche medio litro por minuto. La función que describe la cantidad de litros (lt) que habrá en la piscina a las x horas después de abrir el despiche del desagüe es
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

Choose 1 answer:
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]

The distance an object falls when dropped from a tower varies directly as the square of the time it falls. If the object falls 144 feet in 3 seconds, how far will it fall in 18 seconds?
a.
4536 ft
b.
5832 ft
c.
5184 ft
d.
288 ft
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
