Answer:

6/5 or 1.2

Step-by-step explanation:

First, you need to multiply the length by how much the width is of the length, which is 2/3, so you multiply 1 4/5 by 2/3 and you get 6/5. If you want the decimal form, then the answer will be 1.2.

Step-by-step explanation:

Answer:

The building has a height of 14 feet.

Step-by-step explanation:

At first we construct the geometrical diagram respective to the person-building system, whose result can be seen in the attached image. We proceed to describe each variable:

[tex]h[/tex] - Height of the eye level above the ground, measured in feet.

[tex]H[/tex] - Height of the building, measured in feet.

[tex]\alpha[/tex] - Angle of elevation, measured in sexagesimal degrees.

[tex]\beta[/tex] - Angle of depression, measured in sexagesimal degrees.

[tex]r[/tex] - Distance between eye level and the bottom of the building, measured in feet.

[tex]r'[/tex] - DIstance between eye level and the top of the building, measured in feet.

By using trigonometric ratios and functions we find that height of the building is represented by the following formula:

[tex]H = r\cdot \sin \beta + r'\cdot \sin \alpha[/tex] (Eq. 1)

But [tex]r[/tex] and [tex]r'[/tex] can be obtained by these expressions:

[tex]r = \frac{h}{\sin \beta}[/tex] (Eq. 2)

[tex]r' = \frac{r\cdot \cos \beta}{\cos \alpha}[/tex] (Eq. 3)

By (Eq. 2) in (Eq. 3):

[tex]r'= \frac{h}{\cos \alpha \cdot \tan \beta}[/tex] (Eq. 3b)

Now, we expand (Eq. 1) by (Eqs. 2, 3b):

[tex]H = h + h \cdot \tan \alpha \cdot \tan \beta[/tex]

[tex]H = h\cdot (1+\tan \alpha \cdot \tan \beta)[/tex] (Eq. 4)

If we know that [tex]h = 11\,ft[/tex], [tex]\alpha = 22^{\circ}[/tex] and [tex]\beta = 34^{\circ}[/tex], the height of the building is:

[tex]H = (11\,ft)\cdot (1+\tan 22^{\circ}\cdot \tan 34^{\circ})[/tex]

[tex]H = 13.998\,ft[/tex]

The building has a height of 14 feet.

So that " ⋅ " sign is just the multiplication, and always remember:

WHENEVER YOU MULTIPLY TWO NEGATIVE NUMBERS THE PRODUCT IS ALWAYS POSITIVE

So you just multiply 7 and 4 which is 28 and leave it be.

Answer:

Remembering the properties of numbers is important because you use them consistently in pre-calculus. The properties aren't often used by name in pre-calculus, but you're supposed to know when you need to utilize them.

Step-by-step explanations:

Answer: 13 triangles were used.

Step-by-step explanation:

Each triangle has 3 sides where each square has 4 sides.

Total triangles and squares = 17

Total sides they have = 64

Let x= Number of triangles , y= Number of squares

3x = sides of all triangles , 4x = Sides of all squares.

Now, [tex]x+y=17\ \ \ \ (i)[/tex]

[tex]3x+4x=64\ \ \ \ \ (ii)[/tex]

Multiply 3 on both sides of (i) , we get

[tex]3x+3y = 51\ \ \ \ (iii)[/tex]

Eliminate (ii) from (ii)

x= 13

Put this in (i), we get

[tex]13+y=17\\\\\Rightarrow\ y= 17-13=4[/tex]

Hence, 13 triangles were used.

There were 4 triangles used to frame a geometric pattern

Two are more equations that shares common variables are the system of equations. System of equations can be solved by using elimination method or substitution method .

Use the given information to frame system of  equations.

Assume variables for the unknown

Let x be the number of triangles used and 'y' be the number of squares used

A geometric pattern is made using 17 triangles and squares.

Sum of triangles and squares is equal to 17

[tex]x+y=17[/tex]

the triangles and squares have a total of 64 sides,

Each triangle has 3 sides and each square has 4 sides

[tex]3x+4y=64[/tex]

Solve both the equations using substitution method

[tex]x+y=17\\y=17-x[/tex]

Substitute y in second equation

[tex]3x+4y=64\\3x+4(17-x)=64\\3x+68-4x=64\\-1x+68=64\\-1x=64-68\\-1x=-4\\x=4[/tex]

Now find out y

[tex]y=17-x\\y=17-4\\y=13[/tex]

'x' is the number of triangles used

x=4, so 4 triangles were used

Step-by-step explanation:

[tex]x\geq 1[/tex]

Marcelino will bear a loss of $7.5 and the correct statement is "Marcelino will have a loss of $7.50: his costs are more than his profits".

Given information:

The requirements and cost of making the ballons is:

Item                                             Cost

Thirty Balloons                           $22.50

Ribbon                                        $7.50

Helium Tank Rental                   $15.00

Marcelino sells balloons at the rate of $1.25 per balloon.

The total cost of creating 30 balloons will be,

[tex]22.5+7.5+15=\$\;45[/tex]

Now, after selling 30 balloons, he will earn,

[tex]1.25\times 30=\$\;37.5[/tex]

The earning is less than the cost of making the balloons.

So, Marcelino will bear the loss. The loss can be calculated as,

[tex]45-37.5=\$\;7.5[/tex]

Therefore, Marcelino will bear a loss of $7.5 and the correct statement is "Marcelino will have a loss of $7.50: his costs are more than his profits".

The correct option is;

The inverse of the original conditional statement

Step-by-step explanation:

The converse of a conditional statement is given as follows;

Conditional statement: If p then q            [tex]{}[/tex]                                p → q

The converse of the conditional statement: If q then p  [tex]{}[/tex]        q → p

The contrapositive of the conditional statement: If not q then not p  [tex]{}[/tex]        ~q → ~p

Therefore, the conditional statement is logically equivalent to its contrapositive

The inverse of the conditional statement: If not p, then not q  [tex]{}[/tex]        ~p → ~q

Similarly

The converse of the conditional statement is equivalent to the inverse of the conditional statement.
