Three of the angles of a
quadrilateral measure 36', 72, and
144. Which one of the following could
be the measure of the fourth angle
of the quadrilateral?

Answer:

288πin³

Step-by-step explanation:

Volume of a sphere is expressed as;

V = 4/3πr³

r is the radius = 6 inches

Substitute into the formula

V = 4/3π(6)³

V = 4/3π(216)

V= 864/3π

V = 288π in³

Hence the volume of the sphere is 288πin³

Answer:

He earns $51.02

Step-by-step explanation:

If Michael earns an 8% commission, then he is paid 8% of what he sells it for. Therefore, he earns 8% of $637.75.

Your equation is y = 0.08 × 637.75

y = 51.02

He earns $51.02

Answer:

13.73 hours

Step-by-step explanation:

On a map with a scale of

1 inch= 100 miles

the distance between two cities is 7.55 inches.

We convert from inches to miles

1 inch = 100 miles

7.55 inches = x

x = 7.55 × 100 miles

x = 755 miles

The distance between the two cities = 755 miles

If a car travels 55 miles per hour, about how long will it take to get from one city to another?

We are to calculate the Time

Speed = Distance /Time

Time = Distance/Speed

Hence, the time is calculated as:

755 miles/55 miles per hour

= 13.727272727 hours

≈ 13.73 hours

Answer:

(6x² - 22x + 20) square units

Step-by-step explanation:

The area of a rectangle is calculated as:

Length × Width

From the question

Length = (x - 2)2 = 2x - 4

Widths = 3x - 5

The area of the rectangle =

(2x - 4 ) × (3x - 5)

2x(3x - 5) -4(3x - 5)

6x² - 10x - 12x + 20

6x² - 22x + 20

The area of the rectangle =

(6x² - 22x + 20) square units

3-5x=2

or, -5x=-1

or, x= 1/5

The value of x is 1/5 for equation 3 – 5x = 2

Two or more expressions with an Equal sign is called as Equation.

The given equation is 3 – 5x = 2

Three minus five times of x equal to two

We need to solve for x

3 – 5x = 2

Subtract 3 from both sides

3-3-5x=2-3

-5x=-1

Divide both sides by -5

x=-1/-5

x equal to one by five

x=1/5

Hence, the value of x is 1/5 for equation 3 – 5x = 2

Answer:

we conclude that:

[tex]3\sqrt{125}+4\sqrt{20}=23\sqrt{5}[/tex]    

Hence, the last option i.e. [tex]23\sqrt{5}[/tex] is correct.                      

Step-by-step explanation:

Given the expression

[tex]3\sqrt{125}+4\sqrt{20}[/tex]

Combining the radical expressions

[tex]3\sqrt{125}+4\sqrt{20}[/tex]

let us first solve

[tex]3\sqrt{125}[/tex]

[tex]=3\sqrt{5^3}[/tex]

[tex]=3\sqrt{5^2\cdot \:5}[/tex]

Apply radical rule:  [tex]\sqrt{ab}=\sqrt{a}\sqrt{b},\:\quad \:a\ge 0,\:b\ge 0[/tex]

[tex]=3\sqrt{5^2}\sqrt{5}[/tex]

Apply radical rule:   [tex]\sqrt{a^2}=a,\:\quad \:a\ge 0[/tex]

[tex]=3\cdot \:5\sqrt{5}[/tex]

[tex]=15\sqrt{5}[/tex]

Thus,

[tex]3\sqrt{125}=15\sqrt{5}[/tex]

similarly solving

[tex]4\sqrt{20}[/tex]

[tex]=4\sqrt{2^2\cdot \:5}[/tex]

Apply radical rule:  [tex]\sqrt{ab}=\sqrt{a}\sqrt{b},\:\quad \:a\ge 0,\:b\ge 0[/tex]

[tex]=4\sqrt{2^2}\sqrt{5}[/tex]

Apply radical rule:   [tex]\sqrt{a^2}=a,\:\quad \:a\ge 0[/tex]

[tex]=4\cdot \:2\sqrt{5}[/tex]

[tex]=8\sqrt{5}[/tex]

Thus,

[tex]4\sqrt{20}=8\sqrt{5}[/tex]

so we get

[tex]3\sqrt{125}=15\sqrt{5}[/tex]

[tex]4\sqrt{20}=8\sqrt{5}[/tex]

so the expression becomes

[tex]3\sqrt{125}+4\sqrt{20}=15\sqrt{5}+8\sqrt{5}[/tex]        ∵ [tex]3\sqrt{125}=15\sqrt{5}[/tex] , [tex]4\sqrt{20}=8\sqrt{5}[/tex]

                        [tex]=23\sqrt{5}[/tex]                   ∵ [tex]15\sqrt{5}+8\sqrt{5}=23\sqrt{5}[/tex]

Therefore, we conclude that:

[tex]3\sqrt{125}+4\sqrt{20}=23\sqrt{5}[/tex]    

Hence, the last option i.e. [tex]23\sqrt{5}[/tex] is correct.
