A taxi ride costs $3 plus $2.50 per mile. Write and graph an equation in two variables that represents the total cost of a taxi ride. Let m represent number of miles and c represent the total cost (in dollars) of the taxi ride.

Answers

Answer 1

Answer:

3 + 2.50m = c

Step-by-step explanation:

Since you don't know how many miles you are traveling in the taxi, you can use the variable m to represent miles. 3 is the original fee. So, 3 + 2.50m = c is your answer.

Two fire trucks on the ground on either side of a burning building are 1.3 miles apart. They each measure the angle of elevation to the fire, which are 58 degrees and 52 degrees. How far is each truck from the fire. Step by step explanation.. Please..Thanks..

Answers

Answer:

A-0.5777miles

B-0.7223miles

Step-by-step explanation:

Let A be truck with 58°, B be truck with 52° elevation and C be the position of the fire. We know that the AB is 1.3 miles apart.

-Using sine rule, we find the length of AB and BC as:

[tex]\angle C=180-(58+52)=70\textdegree\\\\\frac{a}{sin \ A}=\frac{b}{sin \ B}=\frac{c}{sin \ C}\\\\\frac{1.3}{sin \ 70}=\frac{b}{sin \ 52}\\\\b=\frac{1.3 sin \ 52}{sin 70}=1.0902mi\\\\\\c=\frac{1.3 sin \ 58}{sin 70}=1.1732[/tex]

#Bisect angle C, and use sine rule again to find the lengths of bisected AB:

[tex]\frac{a}{sin \ A}=\frac{b}{sin \ B}=\frac{c}{sin \ C}\\\\\frac{1.0902}{sin \ 90}=\frac{x}{sin \ (90-58)}\\\\x=\frac{1.0902\ sin \ 32}{sin \ 90}=0.5777mi[/tex]

Truck B's position is calculated as 1.3mi-0.5777miles=0.7223miles

Hence, truck one is 0.5777miles and truck two is 0.7223 miles from the fire.

a rectangle is 68 inches by 42 inches. Find the angles that a diagonal makes with each side of the rectangle.

Answers

Answer:

90⁰

Step-by-step explanation:

Final answer:

The diagonal of the rectangles forms two angles with the sides, about 32 degrees and 58 degrees respectively. These are found using the Pythagorean theorem to find the length of the diagonal, and then the arctan function to find the angles.

Explanation:

To find the angle that the diagonal makes with the sides of the rectangle, first calculate the length of the diagonal which can be found using the Pythagorean Theorem. In a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. We can write this as: c² = a² + b². In this case, the length and width of the rectangle are the two sides (a and b) and the diagonal is the hypotenuse (c).

So a = 68 inches, b = 42 inches. Plugging these into our formula gives: c² = 68² + 42², so c = √[(68²) + (42²)] which approximates to 80 inches.

Next, calculate the angles using the inverse tangent (or arctan) function: θ = arctan(opposite/adjacent). In this case, the angles are = arctan(42/68) and arctan(68/42). This gives us angles of approximately 32 degrees and 58 degrees.

What is the result when the number 22 is decreased by 9.1%?

Answers

Answer:

19.998

Step-by-step explanation:

Take the number and decrease (subtract)  by 9.1% of the original number

22 - 22*9.1%

Change the percent to decimal form

22 - 22*.091

22 -2.002

19.998

Final answer:

The result when the number 22 is decreased by 9.1% is 20.0, after calculating 9.1% of 22, which is 2.002, and subtracting it from 22 and rounding to the nearest tenths place.

Explanation:

To find the result when the number 22 is decreased by 9.1%, you can use the following steps:

Calculate the decrease amount by finding 9.1% of 22: (9.1/100) × 22.

Subtract the decrease amount from the original number: 22 - (9.1% of 22).

Using a calculator, the decrease amount is:
(0.091) × 22 = 2.002.

Then subtract this from the original number:
22 - 2.002 = 19.998.

However, we need to report our final answer to the nearest tenths place since that is the precision of the number 9.1%. Therefore, we round 19.998 to 20.0 to reflect the proper significant figures.

So, the result when the number 22 is decreased by 9.1% is 20.0.

Craig has the following data: 14,14,16,b,1 If the range is 25, what is the value of b?

Answers

Final answer:

The student needs to find the missing number 'b' in a data set, given that the range is 25. Since we know the smallest value is 1, adding the range to that value gives us the largest possible number, which in this case is 26. Therefore, 'b' must be 26 to achieve the specified range.

Explanation:

The student is asking about finding a missing value in a set of numbers given the range of the data set. To find the value of b, we must remember the definition of range: Range is the difference between the largest and smallest values in a set.

With the knowledge that the range is 25, and having the numbers 14, 14, 16, and 1, we identify 1 as the smallest value.

If we add the range to the smallest number (1 + 25), we get the largest number the set could contain, which is 26.

Since the other numbers in the set are all smaller than 26, b must equal 26 for the range to be 25.

In triangle ABC, a = 12, _ B= 25°, and
C= 45°. Find b.

Answers

The value of b is 5.4

Explanation:

Given that ABC is a triangle.

It is also given that [tex]a=12[/tex] , [tex]\angle B=25^{\circ}[/tex] and [tex]\angle C=45^{\circ[/tex]

We need to find the value of b.

The value of b can be determined using the law of sine formula, which is given by

[tex]\frac{a}{sin A} =\frac{b}{sin B} =\frac{c}{sin C}[/tex]

First, we shall find the angle of A.

Since, ABC is a triangle and all the angles in a triangle add up to 180°

Thus, we have,

[tex]\angle A+\angle B+\angle C=180[/tex]

  [tex]\angle A+25+45=180[/tex]

          [tex]\angle A+70=180[/tex]

                  [tex]\angle A=110^{\circ}[/tex]

Thus, the value of angle A is 110°

Let us substitute these values in the law of sine formula.

Hence, we get,

[tex]\frac{12}{sin \ 110^{\circ}} =\frac{b}{sin \ 25^{\circ}}[/tex]

Simplifying, we get,

[tex]\frac{12}{0.9397} =\frac{b}{0.423}[/tex]

Multiplying both sides of the equation by 0.423, we get,

[tex]\frac{12\times 0.423}{0.9397} =b[/tex]

Simplifying, we get,

[tex]\frac{0.5076}{0.9397} =b[/tex]

Dividing, we have,

[tex]5.4=b[/tex]

Thus, the value of b is 5.4

Answers

Answer:

66.25

Step-by-step explanation:

30.50 times 2 is 61 that’s for two caps

61 times 1.086 (1 is for the amount you are actually going to pay .086 is what percent is because you have to move the decimal over two when you are changing percent to decimal) and that comes out to 66.246. you round the 4 to 5 to get to nearest cent and comes out to be 66.25

Answer: $66.25

Step-by-step explanation:

Two baseball cap at $30.5 each is $30.5 ×2 = $61

Sales tax at 8.6% = 8.6/ 100= 0.086

Sales tax = 0.086 × 61

= 5.246

Total amount to be paid = $66. 25

I hope this helps!

The  arc MPN is a major arc, and the length of arc MPN is 79/9π

How to determine the arc length?

The given parameters are:

Ф = 360 - 44

Radius, r = 5

The arc length is then calculated using:

[tex]L = \frac{\theta}{360} * 2\pi r[/tex]

3 tan(θ) sin(θ) − 2 tan(θ) = 0

Answers

Answer:

Note from question, Let K be any integer.  Integer = 1

θ = πk

  θ = 3.142 * 1

  θ = 3.142 in three decimal places

θ = sin⁻¹ (2/3) + 2kπ

   θ = sin⁻¹0.667 + 2*1*3.142

   θ = 0.718 + 6.284

   θ = 7.002 in three decimal places

7.002 , 3.142

Step-by-step explanation:

Considering the equation

3 tan(θ) sin(θ) − 2 tan(θ) = 0

The objective is to solve the equation.

First solve the equation in one period.

3 tan(θ) sin(θ) − 2 tan(θ) = 0

( 3sinθ − 2 ) tanθ = 0

Therefore, 3sinθ − 2 = 0    also   tanθ = 0

            =>  sinθ = 2/3        ,        tanθ = 0

Pick the right equation.

tanθ = 0

    θ = tan⁻¹ 0

    θ = 0

Using the unit circle, the period of tangent functions is π

Then the general solution of the equation is θ = 0 + πk ==> θ = πk

Pick the left equation.

3sinθ − 2 = 0

3sinθ = 2

sinθ = 2/3

    θ = sin⁻¹ (2/3)

As the sine function has period 2π

Then the general solution is θ = sin⁻¹ (2/3) + 2kπ

Step-by-step explanation:

You have to use law of cosines.

take these equations and plug in the variables

a^2=b^2+c^2-2bc cos(a)

b^2=a^2+c^2-2ac cos (b)

c^2=a^2+b^2-2ab cos(c)

you will get something along the lines of

something=cos a

something=cos b

something=cos c

then in a calculator you push inverse cos or cos-1(x) and input the "something" into as x and that answer should be one angle, and repeat it for the rest of the three values.

Please round to the nearest whole number.

Answers

Answer:

11%

Step-by-step explanation:

The margin of error is the standard error times the critical value.

For a proportion, the standard error is:

σ = √(pq / n)

σ = √(0.132 × 0.868 / 1105)

σ = 0.0102

Since n is large, we can approximate the critical value using a normal distribution.  For 99% confidence, the critical value is 2.576.

The margin of error is:

ME = 0.0102 × 2.576

ME = 0.026

The confidence interval is 0.132 ± 0.026.  So the lower limit is 0.106, or 10.6%.  Rounded to the nearest whole number, that's 11%.
