A concrete mixing machine weighing 800 pounds needs to be loaded with rocks and sand. Trucks carrying 120 pounds of sand
and 30 pounds of rocks will be used to load the machine. In order for the machine to function properly, the combined weight
of the machine and the mixing load cannot exceed 2,800 pounds.
Which inequality describes the restriction on truck loads, x, to ensure the mixing machine functions properly?
A. 120x+800 > 2,800
B. 150x + 800 > 2 2,800
C. 800x + 150 < 2,800
D. 150x+800 < 2,800

Answers

Answer 1

The inequality to ensure the mixing machine functions properly is,

D. 150x + 800 < 2800

What are inequalities and their types?

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

From the given information and the statement that the combined weight should not exceed  2800 pounds the inequality that represents the number of loads it can take  to ensure the mixing machine functions properly is,

150x + 800 < 2800.

1. Anil runs around a square park of side 90 m. Rohan runs around a rectangular
park with length 50 m and breadth 40 m. Who runs more and by how much?
Pls Help ASAP Pls​

Answers

Answer:

Anil runs more by 180m.

Step-by-step explanation:

Given that:

Length of side of square park = 90 m

We will find the perimeter.

Perimeter = 4s

Perimeter = 4(90) = 360 m

Measurements of rectangular parks = length 50 m and width 40 m

Perimeter = 2(Length + Width)

Perimeter = 2(50+40) = 2(90) = 180 m

360 m > 180m

Difference = 360 - 180 = 180 m

Hence,

Anil runs more by 180m.

Answer:

$124.27

Step-by-step explanation:

A = Principal(1 + r/n)^nt

r = interest rate

n = # times compounded

t = # years

A = 120 (1 + .035/12)^12(1)

A = 120(1 + .0029)^12

A = 120(1.0029)^12

A = 120 x 1.0353

which of the following is parallel to 8x+3y=1?
1. 3x-8y=1
2.3x+8y=5
3. 8x-3y=2
4.16x+6y=1

Answers

Answer:

4.16x+6y=1

Step-by-step explanation:

The given equation of the line is:

      8x + 3y  = 1

From this line, we need to re-arrange and write in the form of the equation of  a straight line.

        The equation of a straight line is given as:

         y  = mx + c

  8x + 3y  = 1

         3y = -8x + 1

          y  = [tex]\frac{-8x}{3}[/tex]  + [tex]\frac{1}{3}[/tex]  

 The slope of the line is [tex]\frac{-8}{3}[/tex]

  Any line from the given choices that will be parallel to the is must have the same slope as it is.

That line is 16x + 6y  = 1

                         6y  = -16x + 1

                            y = [tex]\frac{-16x}{6}[/tex]  + [tex]\frac{1}{6}[/tex]  

                           y = [tex]\frac{-8x}{3}[/tex]  +  [tex]\frac{1}{6}[/tex]

Find the distance between the points (3, 8) and (-1, 9). Round the distance to the nearest hundredth. 3.87 4.12 5.74 2.24

Answers

Answer:

≈ 4.12 units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (3, 8) and (x₂, y₂ ) = (- 1, 9)

d = [tex]\sqrt{(-1-3)^2+(9-8)^2}[/tex]

   = [tex]\sqrt{(-4)^2+1^2}[/tex]

   = [tex]\sqrt{16+1}[/tex]

   = [tex]\sqrt{17}[/tex]

    ≈ 4.12 ( to the nearest hundredth )

Answer:

The distance between given points is: 4.12 units

Step-by-step explanation:

Given points are:

(3, 8) and (-1, 9)

Here

[tex](x_1,y_1) = (3,8)\\(x_2,y_2) = (-1,9)[/tex]

The distance is calculated using the following formula:

[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Putting the values, we get

[tex]d = \sqrt{(-1-3)^2+(9-8)^2}\\d = \sqrt{(-4)^2+(1)^2}\\d = \sqrt{16+1}\\d = \sqrt{17}\\d = 4.123105...[/tex]

Rounding off to nearest hundredth

d = 4.12 units

Hence,

The distance between given points is: 4.12 units

(30PTS) What are the slopes of the asymptotes of a hyperbola with equation x^2/2^2-y^2/6^2=1

Answers

Answer:

2x2−3y2=6or2x26−3y26=1 or. x23−y22=1or(x−0)2(√3)2−(y−0)2(√2)2=1. This is standard form of the equation of a hyperbola with center.

Step-by-step explanation:

c2 = a2 + b2. Every hyperbola has two asymptotes. A hyperbola with a horizontal transverse axis and center at (h, k) has one asymptote with equation y = k + (x - h) and the other with equation y = k - (x - h).

The slopes of the asymptotes of the hyperbola are +3 and -3.

What is an equation?

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

The standard equation for a hyperbola with a horizontal transverse axis is:

[tex](x-h)^2/a^2 - (y-k)^2/b^2 = 1[/tex]

where (h,k) is the center of the hyperbola, "a" is the distance from the center to the vertices along the x-axis, and "b" is the distance from the center to the vertices along the y-axis.

Comparing this to the given equation:

[tex]x^2/2^2 - y^2/6^2 = 1[/tex]

We can see that h = k = 0, a = 2, and b = 6.

The slopes of the asymptotes are given by:

±(b/a)

So, the slopes of the asymptotes are:

±(6/2) = ±3

Therefore,

The slopes of the asymptotes of the hyperbola are +3 and -3.
