Answer:

One reusable bottle cost $8.12

Step-by-step explanation:

Let

x=total cost of the two reusable bottles

Ms stone has 5/8 if the total cost of the two reusable bottles

5/8 of x=$10.15

5/8*x=10.15

x=10.15÷5/8

=10.15×8/5

=81.2/5

=16.24

x=$16.24

The total cost of of the two reusable bottles=$16.24

If total cost of two reusable bottles=$16.24

Cost of one reusable bottle=$16.24/2

=$8.12

One reusable bottle cost $8.12

Answer: Brent repay $4152.61 to his brother.

Step-by-step explanation:

Formula to calculate compound amount : [tex]A =P(1+\dfrac{r}{4})^{4t}[/tex]

, where P= principal amount

r= rate of interest (in decimal)

t= time

As per given, we have

P= $4000

t= 3 years

r= 1.25% = 0.0125  [we divide a percentage by 100  to write in simple form]

Now, substitute these values in the formula

[tex]A=4000(1+\dfrac{0.0125}{4})^{4\times3}\\\\=4000(1.003125)^{12}\\\\=4000\times1.03815129256\\\\\approx4152.61 \ \ [\text{To the nearest cent.}][/tex]

Hence, Brent repay $4152.61 to his brother.

Answer:

Step-by-step explanation:

Multiplication and division are also inverse operations

15 * 10 = 150

150 ÷10 = 15

Divide 150 by 10 and we get 15 back

The division undoes the multiplication

This also works in reverse

150 ÷ 10 = 15

15*10 =150

The multiplication undoes the division

Answer:

5m - 2.

Step-by-step explanation:

We can use long division to divide the two expressions:

             5m - 2

5m - 2 | 25m² - 20m + 4

            25m² - 10m

           -

            0m² - 10m + 4

                    -10m  + 4

                  -

                      0

The quotient of this operation is 5m - 2.

Answer:

The discriminant of a quadratic equation is a parameter that is used to determine the nature of the roots of the equation. The discriminant can be determined by b2- 4ac. In this case, upon substitution, 25- 4*2*7 = -31 in which the roots are negative and iimaginary.

Step-by-step explanation:

Answer:

The discriminant is -31.

Step-by-step explanation:

The discriminant of an equation is b^2 - 4ac. In this case, a = 2, b = -5, and c = 7.

(-5)^2 - (4 * 2 * 7) = 25 - (8 * 7) = 25 - 56 = -31. Because the discriminant is negative, it is less than 0. That means that there is no real solution.

Hey there! :)

Answer:

x = 8.

Step-by-step explanation:

Starting with:

5x - 1 = 6x - 9

Subtract 5x from both sides:

5x - 5x - 1 = 6x - 5x - 9

-1 = x - 9

Add 9 to both sides:

-1 + 9 = x - 9 + 9

8 = x.

Answer:

x=8

Step-by-step explanation:

We can start by subtracting 5x from both sides

That leaves us with -1=x-9

Then we can add 9 to both sides to cancel out the -9

x=8

Answer:

300

Step-by-step explanation:

First let's square all the integers from 1 to 10 inclusive. We get:

1^2 = 1

2^2 = 4

3^2 = 9

4^2 = 16

5^2 = 25

6^2 = 36

7^2 = 49

8^2 = 64

9^2 = 81

10^2 = 100.

Rounding to the nearest hundred, we get that 1, 4, 9, 16, 36, and 49 all round to 0 and 64, 81, and 100 round to 100.

Therefore, we obtain 

0+0+0+0+0+0+0+100+100+100,

or 300.

Answer:

y = 1

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]

Here (x₁, y₁ ) = (4, - 3) and (x₂, y₂ ) = (- 8, 5), thus the y value of midpoint is

y = [tex]\frac{1}{2}[/tex] (- 3 + 5) = 0.5 × 2 = 1

Answer:

1) [tex]7 \frac{11}{16} [/tex]

2) [tex] \frac{7}{15} [/tex]

Step-by-step explanation:

1) Let's convert the mixed fraction into a improper fraction.

[tex]5\frac{1}{8} \\ = \frac{5(8) + 1}{8} \\ = \frac{41}{8} [/tex]

Let the number be x.

[tex] \frac{2}{3} x = \frac{41}{8} \\ x = \frac{41}{8} \div \frac{2}{3} \\ x = \frac{41}{8} \times \frac{3}{2} \\ x = \frac{123}{6} \\ x = 7 \frac{11}{16} [/tex]

2)[tex]4 \frac{3}{8} = \frac{35}{8} [/tex]

[tex]4 \frac{3}{8} \div 9 \frac{3}{8} \\ = \frac{35}{8} \div \frac{75}{8} \\ = \frac{35}{8} \times \frac{8}{75} \\ = \frac{7}{15} [/tex]

Answer:

y=9/2x-11/2

Step-by-step explanation:

-2y=11-9x

y=11-9x/-2

y=9/2x-11/2

Answer:

y= 9/2x - 11/2

or

y=4.5x -5.5

Step-by-step explanation:

To solve for y, we must get y by itself on one side of the equation.

9x-2y=11

9x is being added to 2y. The inverse of addition is subtraction. Subtract 9x from  both sides.

9x-9x -2y= 11-9x

-2y= 11-9x

y is being multiplied by -2. The inverse of multiplication is division. Divide both sides by -2.

-2y-/2= 11-9x/-2

y= 11/-2 - 9x/-2

y=- 11/2 +9/2 x

or

y= -5.5 +4.5 x

Reorder the terms.

y= 9/2x - 11/2

or

y=4.5x -5.5

Answer:

A,C,and D are parralelograms

The parallelogram are shapes with figures having opposite sides which are parallel

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure

The sum of angles of a parallelogram is 360°

The four types are parallelograms, squares, rectangles, and rhombuses

Properties of Parallelogram

Opposite sides are parallel

Opposite sides are congruent

Opposite angles are congruent.

Same-Side interior angles (consecutive angles) are supplementary

Each diagonal of a parallelogram separates it into two congruent triangles

The diagonals of a parallelogram bisect each other

Given data ,

Let the parallelogram be represented as ABCD

Now , from the figure 1

a)

The figure is having opposite sides are parallel

where AB = CD

And , BC = AD

So , it is a parallelogram

b)

The figure does not have any sides parallel

So , it is not a parallelogram

c)

The shape is having 2 sides as parallel

And , AB = CD

So , it is a parallelogram

d)

The shape is having 2 sides as parallel

And , AB = CD

So , it is a parallelogram

Hence , the parallelogram is solved

Answer:

[tex]g\circ f=\{(1,3),(3,6),(5,8)\}[/tex].

[tex]f\circ g[/tex] does not exist.  

Step-by-step explanation:

It is given that,

[tex]f=\{(1,2),(3,4),(5,6)\}[/tex]

[tex]g=\{(2,3),(4,6),(6,8)\}[/tex]

We need to find the composition gof.

[tex](g\circ f)(x)=g(f(x))[/tex]

Now,

[tex](g\circ f)(1)=g(f(1))=g(2)=3[/tex]

[tex](g\circ f)(3)=g(f(3))=g(4)=6[/tex]

[tex](g\circ f)(5)=g(f(5))=g(6)=8[/tex]

So, [tex]g\circ f=\{(1,3),(3,6),(5,8)\}[/tex].

We need to check whether [tex]f\circ g[/tex] exist of not.

If range of g(x) is subset of domain of f(x), then we can say composition function [tex]f\circ g[/tex] exists.  

Now,

Range of g(x) = {3,6,8}

Domain of f(x) = {1,3,5}

Since range of g(x) is not a subset of domain of f(x), then we can say composition function [tex]f\circ g[/tex] does not exist.  

Answer:

-125/462.

Step-by-step explanation:

5/22 + 3/7 + (-8/21) + (-6/11)

= 5/22 - 6/11 + 3/7 - 8/21        The LCM of 11 and 22 is 22 and of 7 & 21= 21:

= 5/22 - 12/22 + 9/21 - 8/21

= 1/21 - 7/22                              The LCM of 21 and 22 is 462:

= 22/462 - 147/462

= -125/462.

Answer:

If it is on the maximum, then the y-value of the point cannot be any higher and  still be on the graph of the function. If it is on the minimum, the the y-value of the point cannot be any lower and still be on the graph of the function. If it isn't either the maximum or the minimum, it is neither.

Answer:

y = -2/3x + 4

Step-by-step explanation:

Use formula for slope given two points.

m = (y2 - y1)/(x2 - x1)

The two points are (0, 4) and (6, 0)

m = (0 - 4)/(6 - 0)

m = -4/6

m = -2/3

y = -2/3x + b

The y-intercept b is 4.

Answer:

5.5m^2

the area of just the trench is 5.5 m^2

Step-by-step explanation:

The Area of trench only is the total area(trench and garden) minus the Area of garden

Area of trench only = total area(trench and garden) - Area of garden

Area = length × breadth

Substituting the given dimensions;

Total area = 3.5 × 3 = 10.5 m^2

Area of garden = 2.5×2 = 5 m^2

Area of trench only = 10.5 m^2 - 5 m^2

Area of trench only = 5.5m^2

the area of just the trench is 5.5 m^2
