Derive tan(A+B)+tan(A+B)- tan(A+B)+tan(A+B).​

Answer:

186

Step-by-step explanation:

x/200 = 0.93

x = 200(0.93)

x = 186

The number of problems that Indigo did answer correctly in the final exam is 186.

Given that:

Indigo earned a grade of 93% on her multiple-choice history final which had a total of 200 problems.

Total number of problems = 200

So, 100% grade = 200 problems

Let x be the number of problems which is answered correctly to get 93%.

Using the proportional concept,

[tex]\frac{x}{200} =\frac{93}{100}[/tex]

Cross multiply,

100x = 93 × 200

Dividing whole by 100,

x = 93 × 2

x = 186

Hence, the number of problems that are answered correctly is 186.

An architect uses geometry  to charge for their design to design the floorplan of a sructure.

Architects use geometry to help them design buildings and structures. Mathematics can help architects express design images and to analyze as well as calculate possible structural problems.

The shapes and sizes used in the architect’s design are often possible due to mathematical principles.

An example of this would be the Pythagorean Theorem. Architects are required to know college level algebra, trigonometry, probability and statistics, linear programming, calculus I and calculus II. They are also required to obtain a professional degree, gather work experience in an internship setting and pass the Architect registration exam for licensing purposes.

At 7:00 am Wesley complete his third shift if Wesley and two of his friends are driving cross country nonstop and have agreed to take turns driving in 7-hour shifts option (C) is correct.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have:

Wesley and two of his friends are driving cross country nonstop and have agreed to take driving in 7-hour shifts.

Wesley’s first shift starts at 6:00 am

6:00 am = 6h 0m

= 6 + 7

= 13 h = 1:00 PM (Wesley's starts to rest)

Wesley will take a rest for 14 hours (7 + 7)

First shift = 7 + 14 = 21

Second shift = 7 + 14 = 21

Third shift = 7 = 7

= 21 + 21 + 7 = 49

= 49/24 = 2 days + 1 hour

6h + 1h = 7h = 7:00 am

Thus, at 7:00 am Wesley complete his third shift if Wesley and two of his friends are driving cross country nonstop and have agreed to take turns driving in 7-hour shifts option (C) is correct.

Answer:

[tex]LM = 35cm[/tex] and [tex]m \angle H = 98^o[/tex]

Step-by-step explanation:

For this problem, it is critical to understand what the opening statement means.

[tex]Quadrilateral GHJK \cong quadrilateral LMNP[/tex] means that each pair of corresponding sides between shapes are congruent (they have equal length), and each pair of corresponding angles between shapes are congruent (they have equal measure -- or same number of degrees when measured with a protractor).

So, it's important to be able to determine which pairs are the corresponding parts.  When the congruence is given like [tex]Quadrilateral GHJK \cong quadrilateral LMNP[/tex]  the letters are in a particular order.  That order explains the order in which the shape is drawn out, and they put them in the same order for both shapes to mean that those are the letters that correspond with each other.

So, the first letter of each are a corresponding pair, the second letter of each are a corresponding pair, ... etc

In other words, point G and L correspond, point H and K correspond, etc.

To find the corresponding sides, the sides for these shapes are defined by a two adjacent letters (two letters next to each other in the name, or ... as it wraps around the end of the name... the first and last letter).

[tex]\overline{GH} \cong \overline{LM}\\ \overline{HJ} \cong \overline{MN} \\\overline{JK} \cong \overline{NP}\\\overline{KG} \cong \overline{PL}[/tex]

While all of that is true, we only have a few sides with any information in them.  Notice that side GH in the first shape, and sides PL & LM in the second shape are the only sides with anything written.  So, we just need to determine which sides correspond (and thus, are congruent), so that we know how to move forward.  Looking at the list of congruent sides above, we see that  [tex]\overline{GH} \cong \overline{LM}[/tex]

Since the sides (line segments) are congruent, their lengths are equal

[tex]GH = LM[/tex]

...so we can substitute the expressions for each angle into the equation and solve for the unknown value "x"

[tex]GH = LM\\(4x+3)=(6x-13)[/tex]

[tex](4x+3)+13=(6x-13)+13\\4x+16=6x[/tex]

[tex](4x+16)-4x=(6x)-4x\\16=2x[/tex]

divide both sides by 2

[tex]\frac{16}{2}=\frac{2x}{2}\\8=x[/tex]

So, to find the length, LM, we just need to look back at the expression for LM:

[tex]LM = 6x-13\\LM = 6(8)-13\\LM = 48-13\\LM = 35[/tex]

remembering that the lengths are measured in centimeters (as indicated on the diagram): [tex]LM = 35cm[/tex]

To find the corresponding angles, the angles for these shapes are defined by a single letter, so since the points correspond in order, the names of the shapes tell which angles are congruent.

[tex]\angle G \cong \angle L\\\angle H \cong \angle M\\\angle J \cong \angle N\\\angle K \cong \angle P[/tex]

While all of that is true, we only have a few angles with any information in them.  Notice that ∠H in the first shape, and ∠L & ∠M in the second shape are the only angles with anything written.  So, we just need to determine which angles correspond (and thus, are congruent), so that we know how to move forward.  Looking at the list of congruent angles above, we see that  

[tex]\angle H \cong \angle M[/tex]

Since the angles are congruent, their measures are equal

[tex]m\angle H = m\angle M[/tex]

...so we can substitute the expressions for each angle into the equation and solve for the unknown value "y"

[tex]m\angle H = m\angle M\\(9y+17)=(11y-1)[/tex]

subtract 1 from both sides

[tex](9y+17)+1=(11y-1)+1\\9y+18=11y[/tex]

subtract 9y from both sides

[tex]\\(9y+18)-9y=(11y)-9y\\18=2y[/tex]

divide both sides by 2

[tex]\frac{18}{2}=\frac{2y}{2}\\9=y[/tex]

So, to find angle H, we just need to look back at the expression for the measure of angle H:

[tex]m\angle H = 9y+17\\m\angle H = 9(9)+17\\m\angle H = 81+17\\m\angle H = 98[/tex]

remembering that the angle is measured in degrees (as indicated on the diagram): [tex]m \angle H = 98^o[/tex]

Answer:

15°

Step-by-step explanation:

angle FGH = angle HGI ( since GH bisects angle FGI)

that means

(2x + 1) = (3x - 9)

= -x = -8

x = 8

angle HGI = (3x - 9)

= 3(8) - 9

24 - 9

= 15°

Answer:

21

Step-by-step explanation:

To find the measure of <HGI we first need to find the value of x

GH bisects angle <FI which means it divided the angle into two equal parts:

<FGH = <HGI

2x + 1 = 3x - 9 transfer like terms to the same side of the equation

1 + 9 = 3x - 2x

10 = x now replace x with 10

3*10 - 9 = 21

The value of f(x) = 3x² - 2x at x = 4 is 40.

The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x. Mapping or transformation is used to denote a function in math.

Here, the given function;

    f(x) = 3x² - 2x

put the value of x = 4, we get

     f(4) = 3 X 4² - 2 X 4

     f(4) = 3 X 16 - 8

      f(4) = 48 - 8

     f(4) = 40

Thus, the value of f(x) = 3x² - 2x at x = 4 is 40.

Answer:

each bottle of juice was $1.71

Step-by-step explanation

first, subtract the cost of the chips from the total cost

$16.62 - $2.94 = $13.68

now we know the price of all 8 juice bottles. To find the price of each bottle of juice, divide the total price of all 8 juice bottles by 8

$13.68 / 8 = $1.71

$16.62 - $2.94 = $13.68

$13.68/8 = $1.71

Each bottle of juice is $1.71
