Answer:

[tex]x=\frac{1}{r} +1[/tex]

Step-by-step explanation:

[tex]r=\frac{1}{x-1}[/tex]
[tex]r(x-1)=1[/tex]
[tex]x-1=\frac{1}{r}[/tex]
[tex]x=\frac{1}{r} +1[/tex]

Answer:

[tex]x=\dfrac{1+r}{r}[/tex]

Step-by-step explanation:

Given equation:

[tex]r=\dfrac{1}{(x-1)}[/tex]

Multiply both sides by (x - 1):

[tex]\implies r(x-1)=\dfrac{1}{(x-1)} \cdot (x-1)[/tex]

[tex]\implies r(x-1)=1[/tex]

Expand the brackets:

[tex]\implies rx-r=1[/tex]

Add r to both sides:

[tex]\implies rx-r+r=1+r[/tex]

[tex]\implies rx=1+r[/tex]

Divide both sides by r:

[tex]\implies \dfrac{rx}{r}=\dfrac{1+r}{r}[/tex]

[tex]\implies x=\dfrac{1+r}{r}[/tex]

If [tex]x = \frac{1}{r} +1[/tex]

We have:

[tex]xr + 2/3 = 2r\\ < = > xr - 2r = -2/3\\ < = > (x - 2)r = -2/3\\ < = > (1/r + 1 -2) r = -2/3\\ < = > (1/r - 1)r = -2/3\\ < = > (1/r)r - (1)r = -2/3\\ < = > 1 - r = -2/3\\ < = > r = 1 + 2/3 = 5/3[/tex]

ANSWER: r = 5/3 if x = 1/r + 1

Answer:

162°

Step-by-step explanation:

They are on a straight line so add to 180

8x + 10 + 2x - 20 = 180

10x - 10 = 180

10x = 190

x = 19

We want AXB so 8x + 10 where x = 19

8(19) + 10 = 162 so it is 162°

Answer:

162 degrees

Step-by-step explanation:

These two angles add up to 180.

8x + 10 + 2x - 20 =180  Next combine the x terms and the constant terms

10x -10 = 180   Next Add 10 to both sides

10x = 190  D  Next divide both sides by 10

x = 19.  Now that we know x, we can solve for <AXB

8x + 10

8(19) + 10

152 + 10 = 162

Answer:

[tex]w=\frac{420}{p}[/tex]

Step-by-step explanation:

So generally a direct proportion can be expressed as:

[tex]k=\frac{y}{x}[/tex]

essentially where the y/x is equal to some constant value.

Whenever you have an inverse proportion, you can generally express it as:

[tex]k=xy[/tex]

where the product of x and y is equal to some constant value.

So we can check for inverse proportion, by seeing if the xy product is constant

1 * 420 = 420

2 * 210 = 420

3 * 140 = 420

Since the xy (or technically wp, or in general the product of the independent variable and dependent variable) product is constant, this relationship can generally be expressed as: [tex]wp=420[/tex]

We can divide both sides by p, so we can isolate the dependent variable (p)

[tex]w=\frac{420}{p}[/tex]

Answer:

184m^2

Step-by-step explanation:

Ok first we will look at the triangles.

The formula for triangles is 1/2bh

The base in our triangle is 6, and the height is 4. Also, we have 2 such triangles.

so, we need to plug in our values into our formula, and multiply it by 2, since there are 2 triangles.

2( 1 / 2 ( 6 ) ( 4 ) )

2 ( 12 )

24.

The area of the 2 triangles is 24.

Now, the next part is gonna be hard to explain, but I promise the final answer is right.

lets find the area of the rectangle in the middle. That's easy, 6*10 = 60.

Because the top rectangle would connect to the 5m side of the triangle, then the area of the rectangle would be 10*5 = 50

The same thing applies to the bottom rectangle, so its also 50.

24+50+50+60 = 184

The unit is meters(m)

So, 184 m^2

The surface area of the prism based on the net provided will be 184 square meters.

Let h be the height and b be the base of the triangle.

Let L₁, L₂, and L₃ be the length and W be the width of the rectangle.

Then the surface area of the triangular prism will be

Surface area = 2 Area of triangle + 3 Area of rectangle

Surface area = h x b + (L₁ + L₂ + L₃) x W

From the figure, the length of the rectangles will be 5 m, 6 m, and 5m,  and the width is 10 m.

From the figure, the height is 4 m and the base is 6 m of the triangle. Then we have

Surface area = 4 x 6 + (6 + 5 + 5) x 10

Surface area = 24 + 16 x 10

Surface area = 24 + 160

Surface area = 184 square m

The surface area of the prism based on the net provided will be 184 square meters.

Answer:

◘ 12 pears

◘ 3 pineapples

◘ 10 kiwis

Step-by-step explanation:

Let [tex]x[/tex] be the number of pears bought.

Therefore:

• number of pears = [tex]x[/tex]

• number of pineapples = [tex]x - 9[/tex]

• number of kiwis = [tex]x - 2[/tex]

We know that the total cost was $13.50.

This means if she bought [tex]x[/tex] pears at $0.50 each, [tex](x - 9)[/tex] pineapples at $1.50 each, and [tex](x -2)[/tex] kiwis at $0.30 each, the total would be $13.50.

∴  [tex][x \times 0.50] + [(x-9) \times 1.5] + [(x-2) \times 0.3] = 13.50[/tex]

Expanding and multiplying:

⇒ [tex]0.5 x + 1.5x - 13.5 + 0.3x - 0.6 = 13.5[/tex]

Collect like terms:

⇒ [tex]2.3x -14.1 = 13.5[/tex]

Solve for [tex]x[/tex]:

⇒ [tex]2.3x = 13.5 + 14.1[/tex]

⇒ [tex]2.3 x = 27.6[/tex]

⇒ [tex]x = 27.6 \div 2.3[/tex]

⇒ [tex]x = \bf 12[/tex]

Therefore, she bought:

• 12 pears

•  [tex]x - 9[/tex] = 12 - 9 = 3 pineapples

• [tex]x - 2[/tex] = 12 - 2 = 10 kiwis

Marita bought 12 pears, 3 pineapples and 10 kiwis.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

Let x the number of pears bought,

y the number of pineapples bought,

z the number of kiwis bought,

Given that, Marita bought 9 more pears than pineapples and 2 fewer kiwis than pears,

y + 9 = x

y = x -9 and

z + 2 = x

z = x - 2

We know that the total cost was $13.50.

This means if she bought  pears at $0.50 each,  pineapples at $1.50 each, and  kiwis at $0.30 each, the total would be $13.50.

∴  0.50x + 1.50y+ 0.30z = 13.50

Substitute the values of y and z in equation,

⇒ 0.50x + 1.50(x -9)+ 0.30(x - 2) = 13.50

Expanding and multiplying terms in equation,

⇒  0.50x + 1.50x -13.50+ 0.30x - 0.60 = 13.50

Rearrange the like terms and apply the arithmetic operation

⇒ 2.3x - 14.1 = 13.50

⇒ 2.3x = 13.50 + 14.1

⇒ 2.3x = 27.6

⇒ x = 27.6/2.3

⇒ x = 12

Therefore, the number of pears bought = 12

So, the number of pineapples bought = 12 - 9 = 3

And the number of kiwis bought = = 12 - 2 = 10

Hence, Marita bought 12 pears, 3 pineapples and 10 kiwis.

A square has four right angles.

A right angle is a 90⁰ angle.

The diagonals divide each 90⁰ angle by 2

I hope you know what a diagonal is.

It is a line from a corner of the square to the opposite corner. This cuts the square into two equal sides.

After drawing the first diagonal two triangles of equal size will be seen.

After drawing the second diagonal the two triangles that appeared will each be cut into halves.

Now, you'll have four equal triangles.

Step-by-step explanation:

This is a question on some unit conversions.

First we convert 3 pounds to ounces.

Given 16 ounces = 1 pound,

3 pounds = 3 x 16 ounces = 48 ounces

Next, we will find the number of cherries required.

Number of Cherries required = Total weight of cherries needed (in ounces) / Weight per cherry.

= [tex]\frac{48}{0.5}[/tex]

= 48 * 2

Answer:

Hope the picture will help you......

Step-by-step explanation:

As we know, for any function domain is referred to as the set of input values that can be taken for an independent variable in the given function. Range of a function is defined as the set of output values generated for the domain (input values) of the function. In the case of a step function, for each value of x, f(x) takes the value of the greatest integer, less than or equal to x. For example:

[-2.19] = -3

[3.67] = 3

[-0.83] = -1

The domain of this function is a group of real numbers that are divided into intervals such as [-5, 3), [-4, 2), [-3, 1), [-2, 0) and so on. This explains the domain and range relations of a step function.

This can be generalized as given below:

[x] = -2, -2 ≤ x < -1

[x] = -1, -1 ≤ x < 0

[x] = 0, 0 ≤ x < 1

[x] = 1, 1 ≤ x < 2

[tex]\triangle KLU \sim \triangle ETU[/tex]

Since K is first, E is also first, as ∠K matches to ∠E. Since L is second, T is also second, as ∠L matches to angle ∠T.

Answer:

45 degrees

Step-by-step explanation:

OK so

is L and N are equal you can represent that as 2x

the remaining angle should be 90 because right triangles always have a 90 degrees angle somewhere

you know that all three angles of a triangle add up to 180 so that's what the total is

2x+90=180

subtract 90 from both sides

2x=90

divide both sides by 2

x=45
