The radius of the basket ball having volume 452.1 cubic inches is 4.76 inches.

What is the volume?

Volume is the 3 dimentional occupied space by any object. It is measured in SI units [tex]\textnormal{m}^3[/tex] and other derived units like [tex]\textnormal{in}^3[/tex].

All properties of a spherical shape is defined by its radius. The shape of a basketball is spherical hence, the formula of the volume is given by the followin expression:

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

Here, V is the volume of the basket ball and r is the radius of the basket ball.

Rearrange the above equation for [tex]r[/tex].

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

[tex]r=[\frac{3V}{4\pi}]^{1/3}[/tex]

Substitute values.

[tex]V=[\frac{3(452.1 \ \textnormal{cubic inches})}{4\pi}]^{1/3}\\=4.76 \ \text{inches}[/tex]

Hence, the radius of the basket ball is 4.76 inches.

Slope of line 1 is -4/3, slope of line 2 is 3/4, slope of line 3 is 3/4, and  Line 1 and Line 2 are perpendicular, Line 1 and Line 3 are also perpendicular, Line 2 and Line 3 are parallel.

What is slope of a line?

The increase divided by the run, or the ratio of the rise to the run, is known as the line's slope. In the coordinate plane, it describes the slope of the line. Finding the slope between two separate points and calculating the slope of a line are related tasks. In general, we require the values of any two separate coordinates on a line in order to determine its slope.

Slope of a line can be calculated using the formula:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Here, m = slope and (x1, y1), (x2, y2) are two points on the line,

Calculating the slope of line 1 whose points are (-3, 8), (0, 4)

[tex]m = \frac{4 - 8}{0 - (-3)}[/tex]

m = -4/3

Calculating the slope of line 2 whose points are (4, 4), (-4, -2)

[tex]m = \frac{-2 - 4}{ -4 - 4}[/tex]

m = 3/4

Calculating the slope of line 2 whose points are (4, 1), (8, 4)

[tex]m = \frac{4 - 1}{ 8 - 4}[/tex]

m = 3/4

Now we know that if lines are parallel that their slope is equal and when lines are perpendicular the product of their slope is -1,

Therefore, Line 1 and Line 2 are perpendicular, Line 1 and Line 3 are also perpendicular, Line 2 and Line 3 are parallel.

Sketch a graph that shows the relationship between grams of honey and cups of flour needed for a bakery recipe. To know how much honey is needed for 17 cups of flour

Given data:

Let flour x grams plotted on x-axis

honey y grams plotted on y-axis

We have 2 points to find the slope of linear equation

[tex]m = \frac{y_{2}- y_{1} }{x_{2}- x_{1} } = \frac{35-14}{25-10} = \frac{21}{15} = \frac{7}{5} = 1.4[/tex]

[tex](x_{1}, y_{1}) = (10,14)\\ \\(x_{2}, y_{2}) = (25,35)[/tex]

Linear equation is

y = mx+c

[tex]y = \frac{7}{5}x+c = 1.4x+c[/tex]

Adding points (10,14) in above equation

[tex]y = \frac{7}{5}x+c \\\\14 = \frac{7}{5}*10+c\\ \\[/tex]

c = 0

So, the relation between x grams of flour requires y grams of honey is

[tex]y = \frac{7}{5}x[/tex]

or

y = 1.4x

When x = 17

[tex]y = \frac{7}{5}*17 = 23.8[/tex]

Hence the answer is, y = 23.8 g of honey is needed for 17 cups of flour.

Step-by-step explanation:

The equation that represents the proportional relationship between cups and ounces is n = 0.125c

The 4 ounce = 0.5 cup

Here we have to use the unitary method

Unitary method is the method of finding the value of the single unit

One ounce = 0.5 / 4

= 0.125

Where c represents the cups and n represents the ounce

Then,

n = 0.125c

Similarly

1.5 cups = 12 ounce

1 cup = 12 / 1.5

= 8 ounce

Then,

c = 8n

Then the the correct equation is n = 0.125c

Hence, the equation that represents the proportional relationship between cups and ounces is n = 0.125c

Using the concepts of unitary method, we got that 4 cups of  pancake mix will be required to yield 60 pancakes.

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

We are given that one cup of pancake mix will yield 15 pancakes, and we are asked to yield 60 pancakes.

So,15 pancakes will be yielded by as many as pancake mix=1

therefore, 60  pancakes will be yielded by as many as pancake mix=(60/15)=4.

Hence, if one cup of pancake mix will yield 15 pancakes, then  4 cups of pancake mix will be required to yield 60 pancakes.

experimental probability = 0.6

What is experimental probability ?

Actual experiments and sufficient documentation of the occurrence of occurrences serve as the foundation for experimental probability, sometimes referred to as empirical probability. A number of real experiments are carried out in order to ascertain the likelihood of any event. Random experiments are studies that don't have a predetermined outcome. The results of such experiments are unpredictable. The likelihood of random experiments is calculated repeatedly. A trial is a repeating of an experiment that is performed a certain number of times. The experimental probability's mathematical formula is denoted by;

Probability of an Event P(E) = Number of Trials / Total Number of Occurrences of an Event

What is Geometric progression?

A geometric progression, sometimes termed a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio. A geometric progression with the common ratio 3 is, for instance, the sequence 2, 6, 18, 54,... A geometric series having a common ratio of 1/2 is also 10, 5, 2.5, 1.25, etc.

By calculating the product of the values of a set of numbers, the Geometric Mean (GM) is the average value or mean that denotes the central tendency of the data. The average of the data set's numbers is defined by the mean. There are several distinct forms of means, including arithmetic mean (AM), geometric mean (GM), and harmonic mean (HM).

Here 1st term a = -2
