Answer:  Median = 6

==========================================================

Explanation:

Sort the values from smallest to largest: {2, 5, 6, 10, 10}

Now cross off the first and last values to get this smaller set: {5, 6, 10}

Repeat the process one more time and we get this: {6}

This shows 6 is the middle most item of the original sorted set above. Therefore, 6 is the median.

Mike drove 100 miles in a rental car and was charged $58.00. Jane rented the same car after Mike had rented it and was charged $65.00 for 170 miles. Write an equation to represent y, the total rental cost, in terms of x, the number of miles driven.

Answers

Answer:

y= 48 + 0.1x

x= miles driven

Step-by-step explanation:

We need to calculate the fixed and variable cost (per mile) of renting a car. To do that, we will use the high-low method:

Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)

Variable cost per unit= (65 - 58) / (170 - 100)

Variable cost per unit= $0.1 per mile

Fixed costs= Highest activity cost - (Variable cost per unit * HAU)

Fixed costs= 65 - (0.1*170)

Fixed costs= $48

Fixed costs= LAC - (Variable cost per unit* LAU)

Fixed costs= 58 - (0.1*100)

Fixed costs= $48

y= 48 + 0.1x

x= miles driven

A long string with a balloon at the end was tied to the ground. After a breeze came up, the balloon was 55 feet to the right of where it was tied and 30 feet above the ground, as shown in the figure below. What is the slope of the line between the balloon and the point where it was tied?

Answers

Answer:

The slope is 0.55

Step-by-step explanation:

Right Triangles

The string, the ground, and the height of the balloon form a right triangle where the trigonometric ratios are satisfied.

The image below shows the geometric construction. We are required to find the slope the string forms with the ground.

It can be found by using the tangent ratio:

[tex]\displaystyle \tan\theta=\frac{y}{x}[/tex]

Substituting y=30 and x=55

[tex]\displaystyle \tan\theta=\frac{30}{55}[/tex]

[tex]\displaystyle \tan\theta=0.55[/tex]

The slope is 0.55

A) 14°
B) 53°
C) 29°
D) 24°

Answers

Answer:

angle 127° = angle 1 (vertically opposite angles)

now we have all the angles for the triangle

angle x + angle 29° + 127° = 180° ( sum property of triangle)

angle x + 156° = 180°

Angle x = 180° - 156°

Therefore, angle x = 24°

Which is the solution for ln(3x - 5) = ln(11) + ln(2) ?

Answers

Answer:

B: x=9

Step-by-step explanation:

You have to use the property of logarithms

that says ln A + ln B = ln AB.  So here we have

ln (3x - 5) = ln 11 + ln 2 = ln 22

Therefore 3x - 5 = 22, from which x = 9

Answers

perimeter rectangle = 120 cm

let width be = x
thus the length will be = 4x

4x + 4x + x + x = 120
10x = 120

thus, x = 12 cm

so , width = x = 12 cm

length = 4x = 4(12) = 48 cm

Will weighs three times as much as Brenda. Together, they weigh 240
pounds. How much does each of them weigh

Answers

let

brenda: b

will: 3b

b + 3b = 240

4b = 240

b = 60 lbs (BRENDA)

3b = will

3 (60) = will

180 = WILL

The solution is

The weight of Brenda = 60 pounds

The weight of Will = 180 pounds

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the weight of Brenda be = x

Let the weight of Will be = y

Now , Will weighs three times as much as Brenda

Substituting the values in the equation , we get

y = 3x   be equation (1)

And , the weight of Will + weight of Brenda = 240 pounds

So , x + y = 240   be equation (2)

Substituting the value of y from equation (1) in equation (2) , we get

x + 3x = 240

On simplifying the equation , we get

4x = 240

Divide by 4 on both sides of the equation , we get

x = 60 pounds

So , the weight of Brenda is 60 pounds

Substitute the value of x in equation (1) , we get

y = 3x

y = 3 x 60

y = 180 pounds

So , the weight of Will is 180 pounds

Hence , the weight of Brenda is 60 pounds and weight of Will is 180 pounds
