Given container can hold 2143.57 cu. cm. water.

[tex]V=\frac{4}{3}\times \pi \times r^{3}[/tex],

where 'r' is the radius of the sphere.

For given example,

We have been given a spherical container having radius = 8 cm

The amount of water container can hold = the volume of this spherical container

Using the formula of the volume of the sphere,

[tex]V=\frac{4}{3}\times \pi \times r^{3} \\\\V=\frac{4}{3}\times 3.14 \times 8^{3} \\\\V=2143.57~cm^3[/tex]

Therefore, this container can hold 2143.57 cu. cm. water.

Answer: y=10.50x

Step-by-step explanation:

The y in this equation represents the dependent varible which is our output what we are solving for. We know that Rafeal gets $10.50 per hour but we don't know how many hours he works so to represent the time we use the variable x. If we were to solve this we would take the hours that he worked and multiplied the number of hours by $10.50 to get y the cost which he earns.

The equation that represents the given statement will be equal to y = 10.50(x) and y is the dependent variable.

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the data mentioned in the question,

Earning made by Rafael per hour = $10.50

Let the number of hours working is x.

Then, the equation that represents the given statement,

y = 10.50(x)

Here, y is the total money earned by Rafael.

Answer:

b=100

Step-by-step explanation:

not sure how to solve for a

4(x/8 - 2) = 1/4(2x - 1/2) is the complete equations for having infinitely many solutions.

We know two simultaneous equations have a unique solution when they intersect at a point,

when they are parallel they have no solution and when they are coinciding they have an infinite no. of solutions.

Given, 4( x/8 - 2) = 1/4(2x -___.

(1/2)x - 8 = (1/8)x - ___.

Now, RHS is half of RHS so the blank space should be (-8/4) = -2.

And we know if one equation is some constant multiple of another they are also coinciding and have an infinite no. of solutions.

Equation

5.30 = x + 1.85

The percent of the purchase price would be 20% of the sale price.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

First we need to calculate the difference between the purchase and sale price.

$72.00 - $60.00 = $12.00

Since $12 is the increase in dollars.

To increase as a percentage we need to divide the increase by the original purchase price.

12.00 ÷ 60.00 = 0.2

This simply means moving the decimal place two columns to the right;

0.2 x 100 = 20

Therefore, the percent of the purchase price would be 20% of the sale price.

Answer:

1 and 5

2 and 6

3 and 7

4 and 8

Answer:

In bold below.

Step-by-step explanation:

a) 12 10 8 6 4

This is an arithmetic sequence with common difference -2.

nth term = a1 + (n - 1)d

= 12 + (n - 1)-2

= 12  -2n + 2

= -2n + 14.

b) 25 20 15 10 5

This is an arithmetic sequence with common difference -5.

nth term = a1 + (n - 1)d

= 25 + (n - 1)-5

= 25  - 5n + 5

= -5n + 30.

Answer:

y=0x+(-3)

Step-by-step explanation:

Answer: -2 1/2

Step-by-step explanation:

First term = a = -40

Common ratio = 2nd term / First term = 20 / -40 = -1/2

5th term = ar⁴

5th term = -40 × (-1/2)⁴

5th term = -40 × 1/16

5th term = -2 1/2
