Answer:

5.43333 recurring

Step-by-step explanation:

Mean is the average of a set of numbers. That is, the sum of the digits in the set, divided by the number of the digits.

In the question above, we have 9 digits. So we find the sum of the digits divided by 9.

(9.6+2+4.1+8+5.9+2+3.7+6+7.6)/9

48.9/9

5.4333recurring

Answer:

4/12 or 2/6 or 1/3

Step-by-step explanation:

A. The perimeter of quadrilaterals are same when x=2.

B. The area of quadrilaterals are same when x=4.6

Step-by-step explanation:

A. Perimeter of the quadrilaterals must be equal.

Perimeter of square = Perimeter of rectangle

4(6) = 2(2+3x+4)

⇒ 24 = 2(3x+6)

⇒ 24 = 6x + 12

⇒ 6x = 12

⇒ x = 12/6

x = 2

For x=2, the perimeters of both the quadrilaterals are same.

B. Area of the quadrilaterals must be equal.

Area of square = Area of rectangle

(6)² = 2(3x+4)

36 = 6x+8

6x = 28

x = 28/6

x = 4.6

For x=4.6, the area of both the quadrilaterals are same.

Answer:

Erwin have 1 [tex]\frac{1}{2}[/tex]   gallons of lemonade left

Step-by-step explanation:

Erwin had 2 5/12 gallons of lemonade. He spilled 11/12 gallon of lemonade. How much lemonade dose he have left? Write in simplest form

All we need to do is to subtract 11/12 from 2 5/12. But to do this, we will convert 2 5/12 to improper fraction

converting 2 5/12 to improper fraction yields : 29/12

Lemonade have left = Total lemonade - lemonade spilled

                         =          29/12 -  11/12

                         =     18/12

Lemonade have left =18/12

But we can reduce 18/12 to its lowest term

18÷6/ 12÷6      =     3/2

       Lemonade have left = 3/2

We can change to 3/2 to a mixed number to give us 1 [tex]\frac{1}{2}[/tex]    

Therefore Erwin have 1 [tex]\frac{1}{2}[/tex]   gallons of lemonade left

Answer:

(3/2) or (1 1/2) gallons of lemonade

Step-by-step explanation:

Erwin had 2 5/12 gallons of lemonade at his disposal which also translate to 29/12 gallons.

If he spills 11/12 gallon of the lemonade,then the quantity left with him will be (29/12) - (11/12) = 18/12(change to proper fraction): 3/2 or 1 1/2 gallons of lemonade

Answer:

[tex]512\ m^{3}[/tex]

Step-by-step explanation:

Volume of any cube equals a product of all the edge lengths. Since there are 3 edges:

[tex]V = a^{3} = 8^{3} = 512\ m^{3}[/tex]

The required area of the cube with an edge length of 8 meters is 512 cubic meters.

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

here,
A cube has an edge length of 8 meters.
The volume of the cube = a³
The volume of the cube = 8³ = 512 cubic meters

Thus, the required area of the cube with an edge length of 8 meters is 512 cubic meters.

Step-by-step explanation:

Answer:

x=2

Step-by-step explanation:

3x - 9x + 7 - 3 = -8

Combine like terms

Subtract 4 from each side

-6x +4-4 = -8-4

-6x = -12

Divide each side by -6

The number of students in the class is [tex]s=14[/tex]

Explanation:

It is given that there are 6 girls in a music class.

This represents [tex]\frac{3}{7}[/tex] of the entire class.

To determine the number of students in the class, we need to solve the equation [tex]\frac{3}{7}s=6[/tex]

Let us solve the expression for s.

Multiplying both sides of the equation by [tex]\frac{7}{3}[/tex], we have,

[tex](\frac{7}{3} )\frac{3}{7}s=6(\frac{7}{3} )[/tex]

Simplifying the expression, we have,

Answer:

$3600

Step-by-step explanation:

Cost of the car = $8000

The car loses value at 11% each year .

That’s

11% /100% x $8000

0.11 x 8000

$880

11% decrease each year means that the cost of the car is reduced by $880 per year.

Therefore,

Worth of the car in 5 years

= $8000 - ($880 x 5)

= $8000 - $4400

= $3600

The car will be worth $3600 in five years

Answer:

x=6

Step-by-step explanation:

You are correct. x does equal 6

Answer:

Yes

x = 6

Step-by-step explanation:

Given

2x - 5 = 3(1 - x) + 22

First distribute 3 into (1 - x)

We have

2x - 5 = 3 x 1 -3 x X + 22

2x - 5 = 3 - 3x + 22

The expression can be rearranged as

2x - 5 = 3 + 22 - 3x

2x - 5 = 25 - 3x

Add 3x to both sides

3x + 2x - 5 = 25 - 3x + 3x

5x - 5 = 25

Add five to both sides

5x - 5 + 5 = 25 + 5

5x = 30

Divide both sides by 5

5x/5 = 30/5

x = 6

Answer:

36 ft. tall

Step-by-step explanation:

We can easily solve this problem with a simple proportion:

12 feet / height    =     2 feet / 6 feet

6 * 12 = 2h

72 = 2h

h = 36 ft.

It's found that the tree is 36 feet tall.

To find the height of the tree using the lengths of the shadows and the person's height, we can use a proportion based on similar triangles. Since the sun's rays hit both the tree and the person at the same angle, the ratio of the height of the tree to the length of its shadow is the same as the ratio of the person's height to the length of their shadow.

Let's let 'h' represent the height of the tree. We can set up the proportion as follows:

Person's height / Person's shadow length = Tree's height / Tree's shadow length

6 feet / 2 feet = h / 12 feet

Now we solve for 'h' by cross-multiplying:

6 feet * 12 feet = 2 feet * h

72 feet2 = 2 feet * h

Divide both sides by 2 feet to get:

h = 36 feet

Therefore, the tree is 36 feet tall.

Answer:

12 1/7 cars

Step-by-step explanation:

Let the number of cars she'd wash to earn $63 in spending money be A.

Given she saves $22 of her weekly earnings and wants to have at least $63 for spending money.

That means she’d have to make $63 + $22 = $85

The expression is thus

$85 = A x $7

Where A is the number of cars and $7 is the amount she earns for washing one car and $85 is the total amount she has to make .

Therefore,

85 = A x 7

Divide both sides by 7

85/7 = A x 7/7

12 1/7 = A

A = 12 1/7 cars

She must wash 12 1/7 cars to have at least $63 spending money and also have her weekly Savings of $22

Part A: For 100 miles, the cost will be same for both companies.

Part B: Alex should use Drive and Move company as it will cost him less money.

Step-by-step explanation:

Given,

Starting amount of YMI= $40

Per mile charges = $1.99

Let,

x be the number of miles.

y be the total charges.

y = 1.99x+40    Eqn 1

Starting amount of DM = $60

Per mile charges = $1.79

y=1.79x+60    Eqn 2

Part A:

For same charges;

Eqn 1 = Eqn 2

[tex]1.99x+40=1.79x+60\\1.99x-1.79x=60-40\\0.20x=20[/tex]

Dividing both sides by 0.20

[tex]\frac{0.20x}{0.20}=\frac{20}{0.20}\\x=100[/tex]

For 100 miles, the cost will be same for both companies.

Part B:

Total miles = x = 150

Putting x=150 in Eqn 1

y=1.99(150)+40

y=298.5+40

y=$338.50

Putting x=150 in Eqn 2

y=1.79(150)+60

y=268.5+60

y=$328.50

Alex should use Drive and Move company as it will cost him less money.

Answer:

Slope = 2

y-intercept = 1

x-intercept = -0.5

Standard Form ⇒ y - 2x = 1

Step-by-step explanation:

write the equation of the line through (-2 , -3) and (0,1)

The general form of the line is  y = mx + c

Where m is the slope and c is the y-intercept

The slope m = (y₂ - y₁)/(x₂ - x₁) = (1 - [-3])/(0 - [-2]) = 4/2 = 2

∴ y = 2x + c

By substitution with the point (0,1) to find c

1 = 2 *0 + c

c = 1

∴ y = 2x + 1

Or   y - 2x = 1 ⇒Standard Form

Also,

See the attached figure which represents the graph of the line y - 2x = 1

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It is the slope of the line

b: It is the cut point with the y axis

We have the following points:

[tex](x_ {1}, y_ {1}): (0,1)\\(x_ {2}, y_ {2}): (-2, -3)[/tex]

We find the slope:[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-3-1} {- 2-0} = \frac {-4} {- 2} = 2[/tex]

Thus, the equation is of the form:

[tex]y = 2x + b[/tex]

We substitute a point and find b:

[tex]1 = 2 (0) + b\\b = 1[/tex]

Finally, we have:

[tex]y = 2x + 1[/tex]

On the other hand, the equation in the standard form is given by:

[tex]ax + by = c[/tex]

So, according to the slope-intersection equation we have:

[tex]2x-y = -1[/tex]

Answer:

[tex]y=2x+1\\2x-y=-1[/tex]

Answer:

B

Step-by-step explanation:

The formula is Y-Y1= M(X-X1)

So y-4=3(x+2)

Solution:

We have to find the height of lamppost

From the figure in question,

Given is a right angled triangle

Where,

base = 40 inches

height = ?

By definition of tan,

[tex]tan\ 70 = \frac{opposite}{base}\\\\tan\ 70 = \frac{height}{40}\\\\height = tan\ 70 \times 40\\\\height = 2.7474 \times 40\\\\height = 109.89 \approx 110[/tex]

Thus height of lamp post to nearest inch is 110 inches
