Answer:36 in

Step-by-step explanation:

The formula for circumference is: C = 2πr

π = 3.14

r = radius.

The Circumference given to us is 72π. Plug in 72π for C

72π = 2πr

Isolate the variable, r. Divide 2 and π from both sides

(72π)/2π = (2πr)/2π

r = (72π)/2π

r = 36

36

Answer: 72

Step-by-step explanation:

since the formula of circumference is C= Pi times the diameter, In some cases when they don't say what Pi is same thing here. So, you would put the diameter and the pi sign next to each other. So 72 is the diameter.

Answer:

x = 15

Answer:For the cube root function f(x)=3√x f ( x ) = x 3 , the domain and range include all real numbers. Note that there is no problem taking a cube root, or any odd-integer root, of a negative number, and the resulting output is negative (it is an odd function).

Step-by-step explanation:

The domain and range for all cube root functions is set of all real numbers.

The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively. For example, if the relation is, R = {(1, 2), (2, 2), (3, 3), (4, 3)}, then:

Domain = the set of all x-coordinates = {1, 2, 3, 4}

Range = the set of all y-coordinates = {2, 3}

The domain of a cube root function f (x) = ∛x is the set of all real numbers (R) because it can be calculated for all values of x. Its range is also equal to the set of all real numbers because it will result in all real numbers as y-values.

The range of a cube root function is all real numbers except for 0.

Therefore, the domain and range for all cube root functions is set of all real numbers.

Answer:

x = 9.5

this should be the right answer if the same one you had to solve.

Step-by-step explanation:

y = 2x - 4

y = 12 + 3                             combine them

2x - 4 = 12 + 3

    +4         +4                   The 4's cancel each other out

2x = 12 + 7                     Add then divide

 2x = 19

  2x = 19

Answer:

14x and 3 x

Step-by-step explanation:

14x and 3 x are like terms.

This is because they both have 'x'. (They can even be simplified)

Whereas unlike terms are terms which do not contain the same variable or numerical value. (They cannot be simplified with other terms than its like term)

Answer:

x = -0.24 or 3.73

Step-by-step explanation:

[tex]\frac{-b + \sqrt{b^{2} -4ac } }{2a}[/tex] (There's supposed to be a ± between '-b' and the square root)

[tex]x^{2}[/tex] + 4x + 1 ( [tex]ax^{2} + bx + c[/tex] )

a = -1 ( there's no number before [tex]x^{2}[/tex] so its 1 )

b = 4

c = 1

Substitute into the quadratic equation.

[tex]\frac{-4 + \sqrt{4^{2} -4x1x-1 } }{2x-1}[/tex] ( the [tex]x[/tex] is just the multiplication sign )

=  [tex]\frac{-4 + \sqrt{{16} +4 } }{-2}[/tex]

[tex]\frac{-4 + \sqrt{{20} } }{-2}[/tex] = -0.24    [OR]     [tex]\frac{-4 - \sqrt{{20} } }{-2}[/tex] = 3.73

( The answers are to 2 decimal places )

Answer:

x=65°

Step-by-step explanation:

All angles in a triangle add up to 180°

So 180-85-33=62°

90-62=28°

180-87-28=65°

Answer:

x = 23

y = 105

Step-by-step explanation:

It's given that lines 'k' and 'm' are the parallel lines and 'l' is a transversal line.

Therefore, y° + 75° = 180° [Sum of consecutive exterior angles = 180°]

y = 180 - 75

y = 105°

And y° + (4x - 17)° = 180° [Linear pair of angles are supplementary]

105 + (4x - 17) = 180

4x + 88 = 180

4x = 180 - 88

4x = 92

x = 23

Answer: -3-5[tex]\sqrt{3}[/tex] / 5

Answer:

the answer would be $128.40

Step-by-step explanation:

7% times 120 is 8.4

8.4 plus 120 is 128.4

The amount to be pay for coat is $128.4

Step-by-step explanation:

Given:The sales tax rate is 7.25% in California.

The cost for a coat in Los angeles is $120.00.

Now, to find amount to be paid.

Sales tax = 7.00%.

Cost = $120.00.

So, amount to be paid = $120 + 7.00% of $120.00.

[tex]=120+\frac{7.00}{100} *120\\=120+\frac{84}{10} \\=120+\frac{42}{5} \\=128.4!![/tex]

Therefore, the amount to be pay for coat is $128.4

Answer:

Son is 3. Father is 33.

Step-by-step explanation:

Let the present age of the son be 'x' years.

Then father's age will be (x + 30) years

Given : After 12 years, the father will be three times as old as his son. Therefore,

(x + 12)3 = x + 30 + 12

3x + 36 = x + 42

3x - x = 42 - 36

2x = 6

x = 3

The present age of son is 3 years and the present age of the father is 3 + 30 = 33 years.

Option A

Step-by-step explanation:

Given expression is [tex]\sqrt[3]{56x^7y^5}[/tex].

[tex]\sqrt[3]{56x^7y^5}=(56x^7y^5)^{\frac{1}{3}}[/tex]

Answer:

The time it would take to fill up the truck is approximately 344 minutes

Step-by-step explanation:

The given parameters of the truck are;

The volume of the water truck, V = 1,200 gallon

The rate at which water flows from the hose. m = Constant rate

The volume of water in the truck after t₁ = 10 minutes is V₁ = 65 gallons

The volume of water in the truck after t₂ = 15 minutes is V₂ = 82 gallons

Therefore, the rate at which water flows from the hose to the truck, 'm', is given by the equation for the slope of a straight (constant variation) line, as follows;

[tex]m = \dfrac{V_2 - V_1}{t_2 - t_1}[/tex]

Therefore, we have;

[tex]m = \dfrac{82 \, gallons - 65 \, gallons}{15 \, minutes - 10 \, minutes} = 3.4 \, gallons/minute[/tex]

The point and slope form of the straight line equation relationship between the volume in the tank and the time of flow is given as follows;

V - 82 = 3.4 × (t - 15)

Therefore, the slope and intercept form of the equation is given as follows;

V = 3.4·t - 15 × 3.4 + 82 = 3.4·t + 31

∴ V = 3.4·t + 31

When the tank is filled, V = 1,200 gallons, therefore, we have;

1,200 = 3.4·t + 31

3.4·t = 1,200 - 31 = 1,169

t = 1,169/3.4 = 5845/17 = 343.[tex]\overline{8235294117647058}[/tex]

The time it would take to fill up the truck, t = 343.[tex]\overline{8235294117647058}[/tex] minutes ≈ 344 minutes.
