Answer:

4 and -1

Step-by-step explanation:

Let :

Equations formed :

Subtract : Equation 1 - Equation 2

The numbers are : 4 and -1

Answer:

first you have to order the numbers

8, 10, 13, 18, 23, 25, 26, 30

Median is between 18 and 23 so we add them then divide the sum by 2

Median: (18 + 23)/2 = 20.5

First Quartile is between 10 and 13 so we add them then divide the sum by 2

First Quartile: (10 + 13)/2 = 11.5

Third Quartile is between 25 and 26 so we add them then divide the sum by 2

Third quartile: (25 + 26)/2 = 25.5

Range: 30 - 8 = 22

Answer:

[tex]10x^{3}+x^{2} -1[/tex]

Step-by-step explanation:

Standard form means firstly you will combine like terms (which the problem has already done) and then rewrite the polynomial from greatest power to least power.

We have three separate parts to this polynomial:

The part that has the greatest power is [tex]10x^{3}[/tex]. This is because the x is multiplied by a power of 3, which is the largest power given. Next up would be [tex]x^{2}[/tex]. Finally, -1 would come last.

Thus, the rewritten equation should look like this:

[tex]10x^{3}+x^{2} -1[/tex]

Answer:

g(f(x)) = 9x² + 15x + 4

Step-by-step explanation:

Given :

⇒ f(x) = 3x + 4

⇒ g(x) = x² - 3x

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

Solving :

⇒ g(f(x))

⇒ g(3x + 4) = (3x + 4)² - 3(3x + 4)

⇒ g(3x + 4) = (3x)² + 2(3x)(4) + (4)² - 9x - 12

⇒ g(3x + 4) = 9x² + 24x + 16 - 9x - 12

⇒ g(f(x)) = 9x² + 15x + 4

Imagine a triangle with two of the corner points being the points (5,5) and (8,1)

The length and width would be 3 and 4 to find the hypotenuse (distance) do

3^2+4^2=x^2

9+16=x^2

25=x^2

x=5

[tex]here \: is \: your \: answer...[/tex]

Step-by-step explanation:

Let (x1,y1) = (5,5) and (x2,y2) = (8,1)

By using distance formula,

[tex]d \: = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } [/tex]

[tex]d = \sqrt{ {(8 - 5)}^{2} + {(1 - 5)}^{2} } [/tex]

[tex]d = \sqrt{ {(3)}^{2} + {( - 4)}^{2} } [/tex]

[tex]d = \sqrt{9 + 16} [/tex]

[tex]d = \sqrt{25} [/tex]

[tex]d = 5 \: units[/tex]

Therefore, the distance between (5,5) and (8,1) is 5 units

Answer:

  A. 14040 cubic inches

  B. 61 gallons

Step-by-step explanation:

The volume of a cuboid is given by the formula ...

  V = LWH

__

One yard is 36 inches, so 1 yard 3 inches is 36 +3 = 39 inches.

One foot is 12 inches, so 1.5 ft = 1.5×12 = 18 inches.

The volume of the fish tank is ...

  V = (39 in)(18 in)(20 in) = 14,040 in³

The volume is 14,040 cubic inches.

__

One gallon is 16 cups, so 976 cups is 976/16 = 61 gallons.

976 cups equals 61 gallons.

_____

Additional comment

One gallon is 231 cubic inches, so the volume of the tank is actually about 972 cups, or 60.8 gallons.

The expression 163.28 + 75.459 is a sum expression, and the result of 163.28 + 75.459 is 238.739

The expression is given as:

163.28 + 75.459

The expression is best solved using a calculator.

However, in the absence of a calculator, the following steps can be applied.

Expand each term

163.28 + 75.459 = 163 + 0.28 + 75 + 0.459

Reorder the terms

163.28 + 75.459 = 163 + 75+ 0.28  + 0.459

Add the decimals and integers

163.28 + 75.459 = 238.739

Hence, the result of 163.28 + 75.459 is 238.739

Answer:

Step-by-step explanation:

Area = 200.96

Let's find the raidus from the area formula.

200.96 =  π · r^2

Divide both sides by  π !

64 = r^2

square root both sides

r = 8.

Now since we know the raidus we can find the circumferewnce.

c=2*3.14*8

c= 50.24

Answer:

-0.5.

Step-by-step explanation:

2pi - 11pi/6 = pi/6

so the angle is in the fourth quadrant  where the sine is negative.

pi/6 = 30 degrees and we know form the 30-60-90 triangle that sin 30 = 0.5,

therefore sin pi/6 = 0.5

and sin 11pi/6 = -0.5

The exact value of sin(11π/6) radians is -1/2 by using unit circle

To find the exact value of sin(11π/6) radians, we can use the unit circle and trigonometric identities.

The angle 11π/6 radians is in the third quadrant of the unit circle.

In the third quadrant, the sine function is negative.

We can find the reference angle by subtracting 2π (or 12π/6) from the given angle:

11π/6 - 12π/6 = -π/6

The reference angle is -π/6 radians.

In the unit circle, the coordinates for the angle -π/6 are (√3/2, -1/2). The y-coordinate represents the value of sine.

Therefore, the exact value of sin(11π/6) radians is -1/2.

Answer:

x=10

y=[tex]10\sqrt{3}[/tex]

Step-by-step explanation:

Since there is a 30 degree angle, it is a special right triangle, 30 60 90 triangle. The shorter leg represents "a," the longer leg represents "a√3", and the hypotenuse represents 2a.

The triangle has a hypotenuse of 20 and we are trying to find x and y. x=10 because x is the opposite side of 30 degrees and x is half of the hypotenuse. y=[tex]10\sqrt{3}[/tex] because we already know the x value and y is opposite of 60 degrees. As mentioned before, the longer leg represents a√3.

Explanation:

1 gallon = 4 quarts

2 gallons = 8 quarts

1/4 of 8 quarts = 2 quarts

She used 2 quarts for her bedroom and 3 for the hallway. Therefore, she used 2+3 = 5 quarts total.

That leaves 8 - 5 = 3 quarts for the living room.

Answer:

A: 3 Quarts

Step-by-step explanation:

1 gallon = 4 quarts

1/4 of 2 gallons = 1/4 × 2

                         = 1/2 gallon

⇒ 1/2 gallon = 2 quarts

Therefore, Mieko used 2 quarts of paint to paint her bedroom.

If she used 3 quarts to paint the hallway, then

⇒ total number of quarts used = 2 + 3 = 5 quarts

As she bought a total of 2 gallons of paint:

⇒ 2 gallons = 2 × 4 = 8 quarts

Therefore the remaining unused paint (to paint the living room) is:

⇒ total paint - used paid = 8 quarts - 5 quarts

                                         = 3 quarts

Answer:

C is 6.3

Step-by-step explanation:

We can apply the pythagorean theorum to find C.

A is 2, B is 6

A^2 + B^2 = C^2

2^2 + 6^2 = C^2

C^2 = 40

C = 6.32455532

Hey there!

(6^3 * 2^6) / 2^3

= (6 * 6 * 6 * 2 * 2 * 2 * 2 * 2 * 2) / 2 * 2 * 2

= (36 * 6 * 4 * 4 * 4) / 4 * 2

= (216 * 16 * 4) / 8
= 3,456 * 4 / 8

= 13,824 / 8

= 1,728

Looking for something that gives you the result of: 1,728

Team A and Team ran a race. Team A had 28 runners and Team B also had 28 runners.

4 runners from team A finishes the race while 12 runners from team B finishes the race.

Therefore, the percentage from team B that finishes the race can be calculated as follows.

percentage from team B that finishes = 12 / 56 × 100

percentage from team B that finishes = 1200 / 56
