The number of fishing bait he can buy will be 16.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Chompy has $25 to purchase a fishing pole and some fishing bait. The fishing pole costs $12.50 and the fishing bait costs $0.78 each.

The expression will be formed as below:-Let the number of fishing bait is x.

12.50 + 0.78x = 25

0.78x = 25 - 12.5

0.78x = 12.5

x = 12.5 / 0.78

x = 16

Therefore, the number of fishing bait he can buy will be 16.

Last year the chess club had 30 members. This year the club has 24 members.

Last year, the chess club had 30 members. This year, the club has 24 members. Since this year had less than last year ( 30 > 24), the percent will be decreasing.

To find the percent decrease, you have to use the following formula.

[tex]\frac{Difference}{Original} \times 100[/tex]

Difference refers to the difference between the two numbers, 24 and 30. The difference between 24 and 30 is 6. Original refers to the original number, which is last year's amount of members in the chess group. Therefore, original = 30.

Substitute the numbers into the formula.

[tex]\frac{Difference}{Original} =\frac{6}{30} =0.2[/tex]

To convert the decimal to a fraction, multiply the decimal by 100.

[tex]0.2 \times 100 = 20 \%[/tex]

The answer is the number of chess members decreased by 20%.

____

Since I started off by identifying whether it was decreasing or increasing, I did the work a bit differently. When finding the difference, you would usually subtract 30 from 24, which results in -6. Above I used 6, but if you used -6, you would end up with a result of -20%, which means it decreased by 20%. They bot end up with the same result, but you don't always have to first identify whether it's decreasing or increasing.

Answer:

Decreasing

Step-by-step explanation:

The percentages are decreasing because one year the club had 30 members and the present year has 24 members that decreased by 6!

2(2x - 8) should be Gina's expression as it is not equivalent to 4x - 8.

A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.

Given, Steven and Gina each wrote an expression, but only Steven’s expression is equivalent to 4x - 8.

∴ Gina's expressions should be the one that is not equivalent to  4x - 8.

After observing the given options and applying distributive properties we conclude that 2(2x - 8) is Gina's expression as it is 4x - 16.

[tex] y = -\frac{4}{3}x + 4 [/tex]

Step-by-step explanation:

Use the slope-intercept form to write the equation if the line of the graph given.

[tex] y = mx + b [/tex], where,

b = y-intercept, which is where the line cuts across the y-axis = 4.

m = slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - 4}{3 - 0} = \frac{-4}{3} [/tex]

Substitute m = ⁴/3 and b = 4, into the slope-intercept formula to get the equation of the line:

[tex] y = mx + b [/tex]

[tex] y = -\frac{4}{3}x + 4 [/tex]

Answer:

Sam has to get at least a 96 in order to pass the class with a B.

Step-by-step explanation:

To find this you use mean in this format:

Test Scores + x (Exam Grade Needed) / # of Tests ≥ 80 (Which Is a B)

Substitute:

82 + 70 + 72 + 80 + x / 5 ≥ 80

Add:

304 + x / 5 ≥ 80

Get Rid of the Denominator (Multiply Both Sides By 5):

(5) 304 + x / 5 ≥ 80 (5)

Multiply:

304 + x ≥ 400

Isolate x (Subtract 304 From Both Sides):

x ≥ 96

This means that Sam has to get at least (Greater than or equal to) a 96 in order to pass with a B average.

Answer:

A) 25

Step-by-step explanation:

You use x= -b/2a in order to get your maximum so x= -10/ 2(-5) and you get x=1. You plug 1 into the function as h(1)=-5(1)^2 + 10(1)+ 20 which gets you 25

A function assigns the values. The time it will take for the rocket in the air before it reached its highest height is 1 second.

A function assigns the value of each element of one set to the other specific element of another set.

A.) The maximum height of the rocket can be found by differentiating the function to get the maximum value of the height funciton.

dh/dt = -5(2t) + 10

Substitute the differentiated value with 0,

0 = -10t + 10

-10t = -10

t = 1

Therefore, the maximum height will be attained when the time is 1 second.

Now, substitute the value of t as 1 second to get the maximum height,

h(t) =- 5t²+ 10t+ 20

h(1) =- 5(1)² + 10(1)+ 20

h(1) = -5 + 10 +20

h = 25 yards

Hence, the maximum height of the rocket is 25 yards.

B.) The time it will take for the rocket in the air before it reached its highest height is 1 second.

Answer:

x= 4.3125

Step-by-step explanation:

Answer:

x=4+7i and x=4-7i

Step-by-step explanation:

Rewrite the given quadratic equation by completing the square.

x^2-8x=-65

x^2-8x+16=-65+16

x^2-8x+16=-49

(x-4)^2=-49

Now, solve the equation by applying the square root property and isolating x.

(x-4)^2=-49

√(x-4)^2 = √-49

x-4=+7i

x=4+7i

So, the solutions to the given quadratic equation are x+4+7i and x=4-7i.

Answer:

D; $223.74

Step-by-step explanation:

The amount of bill before tax = $193.75

Percentage of tax added by the waiter = 4%

Amount of tax added by the waiter = (4/100) * 193.75 dollars

                                                       = 775/100 dollars

                                                       = 7.75 dollars

Total bill after tax = (193.75 + 7.75) dollars

                           = 201.50 dollars

Percentage of tips that Luca wants to give = 16%

Amount of tips that Luca wants to give = (16/100) * 201.50 dollars

                                                             = 32,24 dollars

The total amount that Luca needs to pay = (201.50 + 32.24) dollars

                                                                = 233.74 dollars

Step-by-step explanation:

Represent my current age with x and my son's current age with y

Two years ago;

[tex]x - 2 = 4 * (y - 2)[/tex]

Eight years ago:

[tex]x - 8 = 10 * (y - 8)[/tex]

Simplify both expressions

[tex]x - 2 = 4 * (y - 2)[/tex]

[tex]x - 2 = 4y - 8[/tex]

Add 2 to both sides

[tex]x - 2 +2= 4y - 8 + 2[/tex]

[tex]x = 4y - 6[/tex]

Substitute 4y - 6 in the second equation

[tex]x - 8 = 10 * (y - 8)[/tex]

[tex]4y - 6 - 8 = 10 * (y - 8)[/tex]

[tex]4y - 14 = 10y - 80[/tex]
