Simplify the fraction 48/162 to the lowest terms.
8/19
2/3
8/27
12/27

Answer:

The answer is "5.7"

Step-by-step explanation:

Using the cosine rule.

[tex]\cos T = \frac{r^2+s^2-t^2}{2rs} \\\\t^2= r^2+s^2-2rs \cos T ........(i)\\\\r=1.7\\s=7.3\\T=15\\\\t^2= (1.7)^2+(7.3)^2-2(1.7)(7.3) \cos 15^{\circ} \\\\[/tex]

   [tex]=2.89+53.29-24.82(0.9659)\\\\=32.2064[/tex]

[tex]t= 5.6751 =5.7[/tex]

1. Dividing fractions means multiplying the reciprocal-- so turn the fraction upside down and multiply by the first.

Answer:

16

Step-by-step explanation:

n-14=2

add 14 on both sides to get 16

In the statement, A number subtracted from 14 is 2 the unknown number

is 12.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, A number subtracted from 14 is 2.

Let the unknown number be 'n'.

∴ 14 - n = 2.

- n = 2 - 14.

- n = - 12.

n = 12.

Answer:

x = 84°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

129° is an exterior angle of the triangle, thus

x + 45° = 129° ( subtract 45° from both sides )

x = 84°

The 2 triangles formed by the tree/ shadow and Jordan/ shadow are similar and ratio of corresponding sides are equal, that is

let h be the height of the tree, then

[tex]\frac{h}{7}[/tex] = [tex]\frac{50}{10}[/tex] = 5 ( multiply both sides by 7 )

h = 35

The height of the tree is 35 ft

Answer:

The dimensions of the smallest piece that can be used are: 10 by 20 and the area is 200 square inches

Step-by-step explanation:

We have that:

[tex]Area = 128[/tex]

Let the dimension of the paper be x and y;

Such that:

[tex]Length = x[/tex]

[tex]Width = y[/tex]

So:

[tex]Area = x * y[/tex]

Substitute 128 for Area

[tex]128 = x * y[/tex]

Make x the subject

[tex]x = \frac{128}{y}[/tex]

When 1 inch margin is at top and bottom

The length becomes:

[tex]Length = x + 1 + 1[/tex]

[tex]Length = x + 2[/tex]

When 2 inch margin is at both sides

The width becomes:

[tex]Width = y + 2 + 2[/tex]

[tex]Width = y + 4[/tex]

The New Area (A) is then calculated as:

[tex]A = (x + 2) * (y + 4)[/tex]

Substitute [tex]\frac{128}{y}[/tex] for x

[tex]A = (\frac{128}{y} + 2) * (y + 4)[/tex]

Open Brackets

[tex]A = 128 + \frac{512}{y} + 2y + 8[/tex]

Collect Like Terms

[tex]A = \frac{512}{y} + 2y + 8+128[/tex]

[tex]A = \frac{512}{y} + 2y + 136[/tex]

[tex]A= 512y^{-1} + 2y + 136[/tex]

To calculate the smallest possible value of y, we have to apply calculus.

Different A with respect to y

[tex]A' = -512y^{-2} + 2[/tex]

Set

[tex]A' = 0[/tex]

This gives:

[tex]0 = -512y^{-2} + 2[/tex]

Collect Like Terms

[tex]512y^{-2} = 2[/tex]

Multiply through by [tex]y^2[/tex]

[tex]y^2 * 512y^{-2} = 2 * y^2[/tex]

[tex]512 = 2y^2[/tex]

Divide through by 2

[tex]256=y^2[/tex]

Take square roots of both sides

[tex]\sqrt{256=y^2[/tex]

[tex]16=y[/tex]

[tex]y = 16[/tex]

Recall that:

[tex]x = \frac{128}{y}[/tex]

[tex]x = \frac{128}{16}[/tex]

[tex]x = 8[/tex]

Recall that the new dimensions are:

[tex]Length = x + 2[/tex]

[tex]Width = y + 4[/tex]

So:

[tex]Length = 8 + 2[/tex]

[tex]Length = 10[/tex]

[tex]Width = 16 + 4[/tex]

[tex]Width = 20[/tex]

To double-check;

Differentiate A'

[tex]A' = -512y^{-2} + 2[/tex]

[tex]A" = -2 * -512y^{-3}[/tex]

[tex]A" = 1024y^{-3}[/tex]

[tex]A" = \frac{1024}{y^3}[/tex]

The above value is:

[tex]A" = \frac{1024}{y^3} > 0[/tex]

This means that the calculated values are at minimum.

Hence, the dimensions of the smallest piece that can be used are: 10 by 20 and the area is 200 square inches

The value of x is 20.

We can figure this out by...

__________________________________________________________

[tex]\frac{3x}{5}-x=\frac{x}{15}-\frac{28}{3}[/tex] but what does x equal?

[tex]\frac{3\cdot20}{5}-20[/tex] = [tex]-8[/tex]

[tex]\frac{20}{15}-\frac{28}{3}[/tex] = [tex]-8[/tex]

Since both are equal to -8, that means [tex]\frac{3\cdot20}{5}-20[/tex] = [tex]\frac{20}{15}-\frac{28}{3}[/tex].

Which means that...

x = 20

Answer:

The ratio of green apples to red apples is .

Step-by-step explanation:

Given,

Number of red apples = 21

Number of green apples = 18

We have to find out the ratio of green apples to red apples.

Solution,

For finding the ratio we have to divide the number of green apples to the number of red apples.

So, we can frame the above sentence as;

Ratio = number of green apples/number of red apples

Now substituting the values, we get;

Ratio= 18/21 = 6/7

Hence The ratio of green apples to red apples is . 6/7
