Answer:
2
Step-by-step explanation:
Slope = ( y2-y1) / (x2-x1)
= (1- (-5)) / (4-1)
= (1+5) / 3
= 6/3
= 2
The slope of the line that goes through the points (1.-5) and (4.1) will be 2. Option D is correct.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. A straight line is a combination of endless points joined on both sides of the point. A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0. The slope 'm' of any straight line is given by:
m =(y₂-y₁)/(x₋-x₁)
It is given that, the line that goes through the points (1.-5) and (4.1).
(x₁,y₁) = (1.-5)
(x₂,y₂)= (4.1)
m =(y₂-y₁)/(x₋-x₁)
m= (1- (-5)) / (4-1)
m= (1+5) / 3
m= 6/3
m= 2
Thus, the slope of the line that goes through the points (1.-5) and (4.1) will be 2. Option D is correct.

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

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
⇒ 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.

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
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
x = -8

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

Ankur estimated the quotient of 15 and one-third divided by (negative 4 and two-thirds) to be 3. Which best describes his error? Ankur multiplied the compatible numbers 15 and –3. Ankur found that the quotient of a positive number and a negative number is negative. Ankur found that the quotient of a positive number and a negative number is positive. Ankur added the compatible numbers 15 and –3.
Answer:
Ankur found that the quotient of a positive number and a negative number is negative
Step-by-step explanation:
Given that:
Quotient of 15 and one-third divided by (negative 4 and two-thirds) = 3
Mathematically,
( 15 1/3) ÷ (-4 2/3) = 3
Here,
Dividend = 15 1/3 (positive)
Divisor = - 4 2/3 (negative)
Dividing a positive Dividend by a negative Divisor will always give a negative quotient
Hence,
15 1/3 = 46 / 3
-4 2/3 = - 14 / 3
46/3 ÷ - 14/3
= 46/3 * -3 / 14
Ankur must have either forgotten or neglected the negative sign in the divisor
The correct option which describes Ankur's error is: Ankur found that the quotient of a positive number and a negative number is positive.
Given that,
Ankur estimated the quotient of 15 and one-third divided by (negative 4 and two-thirds) = 3
We have to find,
Which best describes his error?
According to the question,
The two [tex]15\dfrac{1}{3}[/tex] and [tex]-4\dfrac{2}{3}[/tex] number are mixed fractions.
Ankur estimated the quotient of 15 and one-third divided by (negative 4 and two-thirds) = 3
Then,
Convert the equation into an improper fraction,
[tex]= \rm \dfrac{15\dfrac{1}{3}}{-4\dfrac{2}{3}} \\\\\ Convert \ into \ improper \ fraction\\\\= \dfrac{\dfrac{15\times3+1}{3}}{\dfrac{-4\times 3+2}{3}} \\\\[/tex]
Now simplify the equation,
[tex]= \dfrac{\dfrac{46}{3}}{\dfrac{-10}{3}} \\\\\\ = \dfrac{\dfrac{46}{3} } {\dfrac{3}{-10}} \\\\\\ = \dfrac{-3}{14}[/tex]
The mistake he has committed, while dividing two fractions, he must have forgotten that one of the fractions which is in the denominator bears a negative sign before it.
Ankur forgot to put the negative sign before 3.
Hence, The correct option which describes Ankur's error is: Ankur found that the quotient of a positive number and a negative number is positive.
