The tire with radius of 6 inches when rolled 150 revolutions travels approximately 5654 inches.

An equation is an expression that shows the relationship between two or more numbers and variables.

A tire with a radius of 9 inches that is rolled 150 revolutions and travels approximately 8,482 inches.

For a tire with radius r and that is rolled 150 revolutions and travels approximately 5654 inches:

9/8482 = r/5654

r = 6 inches

Step-by-step explanation:

distribute ---> 6x-15+10_>_25... add 5 to both sides 6x_>_ 30... then divide by 6... x>_5

Answer:

50 and 25

Step-by-step explanation:

y+x=75

y-x=25

y+y=yx and x-x eliminate itself

so now we have the operation 2y= 50, I got the 50 from substrating 25 from 75

now found the value of y, 50/2=25

so y=25

now plug the number in

25+x=75

75-25=50

so x= 50

Answer:

A. (x – 2)(x + 5)(x – 3) on edg

Step-by-step explanation:

Took the test

When a polynomial P(x) is divided by (x-t) then the remainder of the division is equal to P(t). If P(t)=0, then the (x-t) is the factor of the polynomial. The factors of x³-5x+6 are (x+5)(x-2)(x-3).

According to the remainder theorem, when a polynomial P(x) is divided by (x-t) then the remainder of the division is equal to P(t). If P(t)=0, then the (x-t) is the factor of the polynomial.

Since f(–5) = 0, therefore, (x+5) is a factor of the polynomial f(x).

[tex]\dfrac{x^3-19x+30}{x+5} = x^2-5x+6[/tex]

Now, x² -5x + 6 can be factorised as,

x² - 5x + 6

x² - 2x - 3x + 6

x(x-2) -3 (x-2)

(x-2)(x-3)

Hence, the factors of x³-5x+6 are (x+5)(x-2)(x-3).

The volume of a cone is the amount of space in the cone

The radius of the cone is 4.00 millimeters

The given parameters are:

Volume = 150.72 cubic mL

Height = 9 mL

The volume of a cone is calculated as:

[tex]V = \frac 13 \pi r^2h[/tex]

So, we have:

[tex]150.72 = \frac 13 \pi * r^2 * 9[/tex]

Divide

[tex]150.72 = \pi * r^2 * 3[/tex]

Divide both sides by 3

[tex]50.24 = \pi * r^2[/tex]

Rewrite the equation

[tex]50.24 = \frac{22}{7} * r^2[/tex]

Solve for r^2

[tex]r^2 = 50.24 * \frac{7}{22}[/tex]

Solve for r

[tex]r = 4.00[/tex]

Hence, the radius of the cone is 4.00 millimeters

The ratio which best defines relative frequency is, number of times an event occurs:Total number of times an experiment is performed.

Relative frequency of a event is the measure of something happens relative to the total outcomes of that event.

The relative frequency can be given as,

[tex]f_r=\dfrac{f}{n}[/tex]

Here, (f) is the frequency of the number of times data occurred in an event and (n) is the total number of outcomes.

The relative frequency can also be defined as, it is the ratio of subgroup frequency to the total frequency of any event.

Now, the ratio has to be find out which best defines relative frequency. Lets check options,

Answer:

  y = x - 8

Step-by-step explanation:

You want an equation for the line through the points (8, 0) and (3, -5).

The slope of the line can be found using the formula ...

  m = (y2 -y1)/(x2 -x1)

  m = (-5 -0)/(3 -8) = -5/-5 = 1

The y-intercept can be found from the equation ...

  b = y1 -m(x1)

  b = 0 -1(8) = -8

The slope-intercept equation of the line is ...

  y = mx +b

  y = 1·x +(-8)

  y = x -8 . . . . . an equation for the line

Explanation:

Let's find the side length of the cube based on the given surface area.

SA = 6s^2

96 = 6s^2

6s^2 = 96

s^2 = 96/6

s^2 = 16

s = sqrt(16)

s = 4

The cube has side length 4 cm.

Now calculate the total volume.

V = s^3

V = 4^3

V = 4*4*4

V = 64 cubic cm.

-------------------

Extra info:

The unit "cubic cm" can be abbreviated to "cc". So whenever you hear something from a medical tv show "get me 10 cc's of XYZ", that's what they're referring to. Of course the "10" might be some other realistic value, it's just an example.

1 cc = 1 milliliter

Step-by-step explanation:

(n + 2) - (2n + 1)

n + 2 - 2n - 1

-n + 1

Answer:

[tex] \sf \: -n + 1 [/tex]

Step-by-step explanation:

Given information,

→ h(n) = n + 2

→ g(n) = 2n + 1

Now we have to,

→ find the value of h(n) - g(n).

Then required value will be,

→ h(n) - g(n)

→ (n + 2) - (2n + 1)

→ n + 2 - 2n - 1

→ (n - 2n) + (2 - 1)

→ (-n) + (1)

→ -n + 1

Hence, the value is -n + 1.
