The value of radius of water-walking ball is,

⇒ r = 1.003 m

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

A water-walking ball has a volume of approximately 4.19 m³.

Since, We know that;

Volume of sphere = 4/3πr³

Hence, We get;

⇒ 4.19 = 4/3 × 3.14 × r³

⇒ r³ = 1.001

⇒ r = 1.003 m

Thus, The value of radius of water-walking ball is,

⇒ r = 1.003 m

You can do this problem in two ways.
Either the long way or the short and easy way.

Here is the easy way:

You do 180x1.06 to get you their total of $190.80

Or you can do the slightly longer way which finds you the tax amount which then you can add onto the total:

You do 180*0.06 which gets you $10.80 of tax. $10.80 is how much tax they have to pay on top of the $180, then we can do 180+10.80 to get us the grand total of $190.80.

Answer:

[tex]f(n)=f(n-1) + 4(3)^{n-2}[/tex]

[tex]\textsf{where}\quad f(1)=4[/tex]

Step-by-step explanation:

Given sequence:  4, 8, 20, 56, 164

First, work out the difference in the terms:

[tex]4 \underset{+4}{\longrightarrow} 8 \underset{+12}{\longrightarrow} 20 \underset{+36}{\longrightarrow} 56 \underset{+108}{\longrightarrow} 164[/tex]

As the first differences are not the same, work out the second differences:

[tex]4 \underset{\times 3}{\longrightarrow} 12 \underset{\times 3}{\longrightarrow} 36 \underset{\times 3}{\longrightarrow} 108[/tex]

Therefore, the term-to-term rule is:

[tex]f(n)=f(n-1) + 4(3)^{n-2}[/tex]  

[tex]\textsf{where}\quad f(1)=4[/tex]

[tex]f(2)=f(1) + 4(3)^{2-2}=4+ 4(3)^{0}=4+4=8[/tex]

[tex]f(3)=f(2)+4(3)^{3-2}=8+4(3)^1=8+12=20[/tex]

[tex]f(4)=f(3) + 4(3)^{4-2}=20+4(3)^2=20+36=56[/tex]

[tex]f(5)=f(4) + 4(3)^{5-2}=56+4(3)^3=56+108=164[/tex]

The formula for an inverse proportion, knowing that its graph goes through the point: C(-25, -0.2) is y=5/x.

Let m and n are two variables.

Then m and n are said to be inversely proportional to each other if

[tex]m = \dfrac{c}{n} \\\\ \text{or} \\\\ n = \dfrac{c}{m}[/tex]

(both are equal)

where c is a constant number called constant of proportionality.

This inversely proportional relationship is denoted by

[tex]m \propto \dfrac{1}{n} \\\\ \text{or} \\\\n \propto \dfrac{1}{m}[/tex]

As visible, increasing one variable will decrease the other variable if both are inversely proportional.

The formula for the inverse function is given as,

[tex]y=\dfrac{c}{x}[/tex]

Here, c is constant.

The graph goes through the point: C(-25, -0.2). For the inverse function.

[tex]-25\propto\dfrac{1}{-0.2}\\-25=\dfrac{c}{-0.2}\\c=-25\times-0.2\\c=5[/tex]

Put the value in the above function,

[tex]y=\dfrac{5}{x}[/tex]

This is the required function.

Hence, the formula for an inverse proportion, knowing that its graph goes through the point: C(-25, -0.2) is y=5/x.

Inequality refers to the phenomenon of unequal and/or unjust distribution of resources and opportunities among members of a given society. The term inequality may mean different things to different people and in different contexts.

According to the question

Julia and her children went into a restaurant where ,

hamburgers (xx)= $7 each

tacos (yy) = $2.50 each.

Julia has $60 to spend and must buy a minimum of 14 hamburgers and tacos altogether.

i.e,    xx + yy ≥ 14  ----------------------------(1)

       7xx + 2.5yy ≤ 60 ----------------------(2)

from equation (1) and (2)  graph attached ...

solving both equation

multiplying equation (1) with -7

-7xx + -7yy ≤ -98 ----------------(3)

now adding equation (3) and (2)

-7xx + -7yy ≤ -98

7xx + 2.5yy ≤ 60

=   - 4.5yy ≤ -38

Answer: 726 meters²

Step-by-step explanation:

   We will need to find the area of five shapes. The base, the top/bottom, and the two triangle sides.

      The area of a triangle is B * H / 2. Since we have two congruent triangles, I will not be dividing by two.

14 * 24 = 336 meters²

-> This value is for both of the triangle faces

      The rectangular bottom is L * W

14 * 10 = 140 meters²

      The two rectangles for the top and bottom will also be L * W. Since these are congruent, I will find the area of one and multiply it by two.

10 * 25 = 250 meters²

      Now I will add them all together for the total surface area:

336 + 140 + 250 = 726 meters²

  -> I don't see this as an option choice listed. I will review my work, but I am currently confused on the options they provide.

Answer:

56.52 cm

Step-by-step explanation:

Since the circular base has radius of 9 cm. Therefore the base’s circumference is:

[tex]\displaystyle \large{C=2\pi r}[/tex] where r is radius and C is circumference.

Input r = 9 in:

[tex]\displaystyle \large{C=2\pi \cdot 9}\\\displaystyle \large{C=18\pi}[/tex]

Since π is given to be 3.14:

[tex]\displaystyle \large{C=18\cdot 3.14}\\\displaystyle \large{C=56.52}[/tex]

Therefore, the base’s circumference is 56.52 cm

Answer:

Answer:

q = 4

Step-by-step explanation:

given p and q vary inversely then the equation relating them is

p = [tex]\frac{k}{q}[/tex] ← k is the constant of variation

to find k use the condition p = 8 when q = 6 , that is

8 = [tex]\frac{k}{6}[/tex] ( multiply both sides by 6 )

48 = k

p = [tex]\frac{48}{q}[/tex] ← equation of variation

when p = 12 , then

12 = [tex]\frac{48}{q}[/tex] ( multiply both sides by q )

12q = 48 ( divide both sides by 12 )

q = 4
