The fraction ( 8/10 ) when converted into a decimal number is equal to 0.8.

The decimal number system is frequently used to express both integer and non-integer quantities. The Hindu-Arabic numeral system has been expanded to include non-integer values. Decimal notation is the name for the method used to represent numbers in the decimal system.

The number of shots fired by Marlin should be expressed as a decimal number.

We know that,

Marlin made 8 shots out of 10 shots which is in fraction, it is 8/10.

However, since we are dividing by 10, we shall shift the decimal point of 0.8 to the left (the zero is not really important as it only represents a place value )

Or,

( 8 /10) = ( 4 / 5 ) = 0.8

Therefore, the fraction of the shots Marlin made is 0.8.

Addie's income by running a sandwich delivery service is given by the function y = 12x + 5, which has a domain and range of [0 , +∞) and [5 , +∞), respectively.

In mathematics, a function is the representation of the relationship of a set of input(X) and its corresponding output(Y). The set of x is called the domain while the set of the corresponding y is the range.

If Addie runs a sandwich delivery service. her income can be measured using the function

y = 12x + 5

where x = number of sandwiches she delivers

y = income

The domain of a function is the set of values that we are allowed to plug into our function. The domain of any function of x is always the set of all real numbers but, reasonably speaking, we must consider the situation given. The number of sandwiches she delivers can only range from 0 to positive infinity, not negative.

domain : {x | x ≥ 0} or [0 , +∞)

On the other hand, the range of a function is the set of values of the function after plugging in the value of x.

Substituting our domain [0 , +∞) in the function.

y = 12x + 5

y = 12(0) + 5

y = 5

y = 12(+∞) + 5

y = +∞

range : {y | y ≥ 5} or [5 , +∞)

After solving the equation or inequality, x is equal to 2/3, -20/3 for the equation |3 x+9|=11

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

⇒ |3 x+9| = 11

For positive case                              

⇒  (3 x+9) = 11

⇒ 3x = 11 - 9

⇒ 3x = 2

⇒ x = 2/3

For negative case

⇒  -(3 x+9) = 11

⇒ -3x -9 = 11

The probability of the spinner's point landing on green is 22.23%.

A pie is a kind of chart that displays data in the form of a circular graph.

We understand that the total value of the pie is always 100%. It is also understood that a circle does have a circumference of 360°. As an outcome, the total of all data points equals 360°. There appear to be mainly two pie chart formulas based on these:

When a circle is completely rotated, it forms a 360-degree angle in the center.

At the center of the circle, a complete rotation yields 360 degrees.

The total percentage of all colors is 100%.

Divide a value of green by 3.6 since 360 degrees / 100% = 3.6.

The total percentage of green displayed by the spinner's pointer is 80%.

P (probability of the cursor landing on green) = 80/3.6

Probability P (cursor landing on green) = 22.222... = 22.23 (approx.)

As a result, the probability which the pointer will land on the green is 22.23%.

The diameter of circle is 10.0 feet.

We are given the area of circle. The formula of area with respect to diameter is as follows -

Area = 1/4πd², where d represents diameter of circle.

Taking the value of π as 3.14.

Rewriting the equation according to diameter -

d² = (area×4)÷π

Now, keep the values in formula to find the diameter of circle.

d² = (79×4)÷3.14

Performing multiplication on the Right hand side of the equation

d² = 316÷3.14

Performing division on the Right hand side of the equation

d² = 100.6

d = √100.6

Taking square root on the Right hand side of the equation

d = 10.03 feet

Rounding to nearest tenth -

d = 10.0 feet

Hence, the diameter of circle is 10.0 feet.

The 3 tv stations will announce the news again after 12 hours at 7 in the evening which is calculated by taking the LCM of the 3 intervals.

LCM or lowest common multiple of 2 or more numbers is defined as the minimum number which is lowest multiple of of the 2 or more numbers which is equal.

In mathematics and number theory. Since the result of dividing an integer by zero is not defined this definition only applies if both x and y are not equal to zero.  However, given that 0 is the only common multiple of x and 0, some authors define LCM(x,0) as 0 for all x.

The intervals in which channels announce the news are 2 hours, 3 hours and 4 hours.

So we have to find the LCM of the numbers.

LCM(2,3,4)=12 as 12 is the smallest integer which is divided by all the other 3 numbers.

So the news channels will announce the news after 12 hours.

Since they announced at 7 in the morning so they would all announce the news again at 7 in the evening.

The evaluation of the given functions are as follows;

1. f(x) = 3 - x

g(x) = -2•x

Therefore;

g(fx) = -2 × f(x)

Which gives;

-2 × (3 - x) = -6 + 2•x = 2•x - 6

g(fx) = 2•x - 6

B. 2•x - 6

2. f(x) = 3 - x

g(x) = -2•x

f(g(x)) = 3 - (-2•x) = 3 + 2•x

f(g(x)) = 3 + 2•x

f(g(2)) = 3 + 2×2 = 7

The correct option is therefore;

C. 7

3. f(x) = 3 - x

g(x) = -2•x

Therefore;

g(fx) = 2•x - 6

g(f-1) = 2×(-1) - 6 = -8

C. -8

4. F(x) = 2•x - 1, G(x) = 3•x + 2, H(x) = x²

F(G(x)) = 2•(3•x + 2) - 1 = 6•x + 3

F(G(x)) - F(x) = 6•x + 3 - (2•x - 1) = 4•x + 4

A. 4•x + 4

5. F(x) = 2•x - 1, G(x) = 3•x + 2, H(x) = x²

G(H(x)) = 3•x² + 2

G(H(1)) = 3×1² + 2 = 5

A. 5

6. F(x) = 2•x - 1, G(x) = 3•x + 2, H(x) = x²

F(G(H(x))) = 2•(3•x² + 2) - 1 = 6•x² + 3

F(G(H(2))) = 6×2² + 3 = 27

B. 27

7. F(x) = 2•x - 1, G(x) = 3•x + 2, H(x) = x²

H(x + a) - H(x) = (x + a)² - x² = 2•a•x + a²

B. a² + 2•a•x

8. (H(x + a) - H(x))/a = (a² + 2•a•x)/a

(a² + 2•a•x)/a = a + 2•x = 2•x + a

A. 2•x + a

9. F(x) = 2•x - 1, G(x) = 3•x + 2, H(x) = x²

F(x) + G(x) + H(x) = 2•x - 1 + 3•x + 2 + x² = x² + 5•x + 1

C. x² + 5•x + 1

10. f(x) = 2•x² - 3•x + 1

f(3) - f(2) = 2×3² - 3×3 + 1 - (2×2² - 3×2 + 1) = 7

B. 7

11. G(x) = 5•x - 2

G^(-1)(x) = (G(x) + 2)/5

Which gives;

G^(-1)(x) = (x + 2)/5

A. (x + 2)/5

12. f(x) = 2/(x - 6)

The inverse is therefore;

(2/f(x)) + 6

The inverse of f(x) is therefore;

(2/x) + 6

13. g(x) = (5•x - 5)/4

(4•g(x) + 5)/5 = (4/5)•g(x) + 1

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that Ferrera is 3/4 as old as June, and Tomasso is 1. 1/2 times as old as Ferrera.

The number of the times will be calculated as below:-

F = ( 3 /  4) J

T = 1 ( 1 / 2 ) F
