Expression will have a value of 116 for the specified values of j and k.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

Given an expression  -4j + 12k

where given, j = -8

and k = 7

Substituting the values in the given expression

=> -4 * -8 + 12 *7

=> 32 + 84

=> 116

Therefore, the value of expression for the given values of j and k will be 116.

Answer:

The amount of sales tax collected is $78.35

Step-by-step explanation:

Percentages

The gross receipts for the day were $1645.35, including a 5% sales tax.

If a percentage is already included (added) to a certain quantity, then it's not the original quantity or 100%.

The problem states that the gross receipts already include a 5% sales tax, thus the receipts are 100+5=105% of the net sales.

This means the net sales were $1645.35 / 105 * 100 = $1567

Subtracting $$1645.35 - $1567 = $78.35 we get the amount of sales tax.

The amount of sales tax collected is $78.35

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.

Answer:

[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:

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.

Need a calculator

Step-by-step explanation:

This will be hard to explain without the ability to draw an example.

The one thing you can memorize is SOH - CAH - TOA

This stands for SIN(Opposite/Hypotenuse), COS(Adjacent/Hypotenuse) and TAN(Opposite/Adjacent).

When you know the angles of a right triangle and at least one side length, you can get the length of all the sides.

So a right triangle has two legs (sides) and the hypotenuse.  If you use the first angle ( 30 degrees)  you can use the formulas above to calculate the side length.

Pick either the SOH or the CAH.  Let's use SOH and write out the equation:

SIN(30 degrees) = Opposite Side divided by the Hypotenuse (11mm)

You can solve for the Opposite Side by multiplying both sides of the equal sign with 11mm.    You end up with SIN(30 degrees) X 11m = Opposite Side.

So the side directly across from the 30 degree angle should be 5.5mm

You can do the exact same thing with the 60 degree angle.

SIN(60 degrees) = Opposite Side divided by Hypotenuse (11mm)   OR

SIN(60 degrees) X 11mm = Opposite Side

This comes out to about 9.5mm

You can check the math by using the other equation CAH

Start with the 30 degree angle and solve for the adjacent side.  This is the side that is touching the 30 degree angle.  Equation will be

COS(30 degrees) X 11mm = Adjacent Side  or  about 9.5mm

The other equation will give you the side that is touching the 60 degree angle.

COS(60 degrees)  X 11mm = Adjacent Side or  5.5mm

You can also use one last thing to check your math.  The Pathagorean Theorem says in a right triangle  [tex]A^{2}[/tex] + [tex]B^{2}[/tex] = [tex]C^{2}[/tex] where C is the hypotenuse and A and B are the two sides.

[tex]5.5^{2}[/tex]  +  [tex]9.5^{2}[/tex]  should equal  [tex]11^{2}[/tex].  Give or take a few decimal places, it's almost exactly 11 (10.977 to be exact).

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.

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.
