The child that will have a greater percentage of increasing amounts is; The child with original amount of $500

The amount that has increased from the initial number to the final number in terms of 100 parts of the original is essentially what the concept of percentage increase refers.

We are given that the original amount found in their savings account are;

First child; A = $500

Second child; B = $300

Thus the first child denoted by A has greater amount in savings compared to the second child and as such child A will have a greater percentage of increasing amounts.

The three consecutive odd integers are 17, 19 and 21 respectively.

Linear equations are equations that has a leading degree of 1. Given the three consecutive odd numbers to be

2x+1, 2x+3 and 2x+5

If the sum of the smallest number and middle number is 27 less than three times the largest number, then;

2x + 1 + 2x + 3 = 3(2x+5) - 27

Simplify

4x + 4 = 3(2x) + 3(5) - 27

4x + 4 = 6x + 15 - 27

4x - 6x = 15 - 27 - 4

-2x = -16

x = 16/2

x = 8

Determine the numbers

Smallest number = 2x + 1

Smallest number = 2(8) + 1 = 17

Middle number = 2x + 3

Middle number = 2(8) + 3

Middle number = 19

Largest number = 2(8) + 5

Largest number = 21

Hence the three consecutive odd integers are 17, 19 and 21 respectively.

To receive the greatest discount, the customer should first apply the membership discount and then take the rebate.

We are given that:

Rebate a customer receives if he buys a regular priced CD at $ 13 each = $ 5.

If a customer registers for the store member, he get a discount = 15 %.

Now, let the regular priced CD purchased be x and the application for store member be y.

So, the functions will become:

For rebate:

R (x) = 5 x

For discount:

M (y) = 15 % of x

M (y) = 0.15 x

Now, the amount a customer has to pay if she takes the membership and then takes the rebate =(1 − 0.15) (13 x) − 5 x = 6.05 x

And, if he takes the rebate first and then take the membership, he pays = (13 - 5 x)( 1 - 0.15) = 6.8 x

Therefore, we get that, to receive the greatest discount, the customer should first apply the membership discount and then take the rebate.

If the two functions be f(x) = 3x² - 11x - 4 and g(x) = 3x + 1 then

(fg)(x) = f(x)g(x) = [tex]$$9x^3[/tex] - 30x² - 23x - 4

(f/g)(x) = f(x)/g(x) = x - 4

Function operations are the rules we use to solve functions. There is a specific way to deal with function addition, multiplication, and division.

Function composition is a mathematical operation that takes two functions f and g and produces a function h = g f such that h(x) = g(f(x)). The function g is applied to the result of applying the function f to x in this operation.

Let the two functions be f(x) = 3x² - 11x - 4 and g(x) = 3x + 1.

(fg)(x) = f(x)g(x)

= (3x² - 11x - 4) (3x + 1)

simplifying the above equation, we get

= 3x² [tex]*[/tex] 3x + 3x² [tex]*[/tex] 1 - 11x [tex]*[/tex] 3x - 11x [tex]*[/tex] 1 - 4 [tex]*[/tex] 3x - 4 [tex]*[/tex] 1

= [tex]$$9x^3[/tex] - 30x² - 23x - 4

Therefore, (fg)(x) = f(x)g(x) = [tex]$$9x^3[/tex] - 30x² - 23x - 4

(f/g)(x) = f(x)/g(x)

Where, f(x) = 3x² - 11x - 4 and g(x) = 3x + 1.

f(x)/g(x) =  (3x² - 11x - 4)/(3x + 1)

= [(3x + 1)(x - 4)]/(3x + 1)

canceling the common factors we get

= x - 4

Therefore, f(x)/g(x) = x - 4

A rational number is one that can be defined as the ratio or fraction a/b of two numbers, where a and b are the numerator and denominator, respectively. Here the integer numbers a and b are co prime numbers.

For example 8/7 is a rational number and all integers are rational numbers.

Any combination of terms that have undergone operations like multiplication,addition, subtraction, division is known as an algebraic expression.

it is given that the expression is of the form ∛(a)⁷ .

We know that the n-th root of a variable x ([tex]\sqrt[n]{x}[/tex]) can also be written as

[tex]x^{\frac{1}{n} }[/tex].

Therefore  ∛(a) can be written as [tex]a^{\frac{1}{3} }[/tex] . Now the complete expression is ∛(a)⁷.

So [tex](a^{\frac{1}{3} })^7=a^{\frac{7}{3} }[/tex] and we know that 7/3 is a rational number.

Therefore the expression can be written as [tex]a^{\frac{7}{3} }[/tex] using rational exponents.

points of discontinuity:

In rational functions, points of discontinuity are defined as fractions with undefined or zero as their denominator. When the denominator of a fraction is 0, the fraction is no longer defined and shows up as a hole or break in the graph.

points of discontinuity removable:

A point on the graph that is removable discontinuity is one that may be filled in with a single value despite not existing.If an is zero for a factor in the denominator that shares a factor with a factor in the numerator, a removable discontinuity at x=a in the graph of a rational function occurs.

points of discontinuity non removable:

A function's break that cannot be repaired with a single point is referred to as a non-removable discontinuity. It cannot be filled in with a single point, a vertical asymptote (a vertical line that the graph approaches but never crosses because the function is undefined at that x-value) is non removable.

The possible values of angles A and C are;

60° and 70° or 55° and 75°

An acute triangle is a triangle that has all the measures of its angles to be less than 90°.  This means that none of the angles is greater than 90°

Since sum of the angles in a triangle is equal to 180°, then it means that;

∠A + ∠B + ∠C = 180°

We are given that;

∠B = 50°

Thus;

50° + ∠A + ∠C = 180°

∠A + ∠C = 180° - 50°

∠A + ∠C = 130°

It should be noted that all the angles of the acute triangle are also different.

A linear equation that relates the cost of c in dollars of renting a truck to the number x of miles driven is c = 0.09x + 39, and the cost of renting the truck if the truck is driven 187 miles and 319 miles is equal to $55.83 and $67.71 respectively.

If the rental company rents a truck by charging $34 and 0.09$ per mile, the liner equation can be given as

c = 0.09x + 39

where c represents the cost in dollars of renting the truck and x represents the number of miles

If the truck is driven 187 miles, it can be calculated using the linear equations as follows,

c = 0.09x + 39

As x = 187

c = 0.09 (187) + 39

c = 16.83 + 39

c = 55.83

If the truck is driven 319 miles, it can be calculated using the linear equations as follows,

c = 0.09x + 39

As x = 319

c = 0.09 (319) + 39

c = 28.71 + 39

c = 67.71

Answer:

The value behind a decimal point isn't increased by zeros, zeros are actually just placeholders

Step-by-step explanation:

When written as a fraction, 0.116 can be found to be the equivalent of 29 / 250

The value of 0.116 has 3 decimals after the decimal point. This means that it is a thousandth decimal.

The fraction form is therefore:
= 116/1,000

You can then take this to be simplest form:
= (116 / 2) / (1,000 / 2)

= 58 / 500

= (58 / 2) / (500 / 2)

= 29 / 250
