The algebraic expression to represent the amount of money Jenny will earn in d days, given that she earns $30 per day, is 30d.

The question is asking to write an algebraic expression to represent the amount of money Jenny will earn working at a supermarket for a certain number of days, where she earns $30 per day. In algebra, we often use variables to represent unknown quantities. In this case, we will use d to represent the number of days.

In one day, Jenny earns $30. Therefore, to determine how much she earns in multiple days, we multiply the number of days by the amount she earns each day. If she works 'd' days, Jenny will therefore earn 30d dollars.

To determine which table allows more square arrangements, we find the square root of the total number of items on each table. As the square root of 180 (number of cookies) is larger than the square root of 150 (number of cupcakes), the table with the cookies allows more square arrangements.

To determine which table allows more square arrangements, we need to find the square root of the total number of mini cupcakes and mini cookies on each table. This is because a square arrangement means that the number of items along the length and the width are the same, which is the definition of a square root.

For the cupcakes, the square root of 150 is approximately 12.25, which means you can't form a perfect square arrangement as you can't have a fraction of a cupcake. So, you can arrange 12 cupcakes in a row and a column to form a nearly square array with 144 cupcakes, and there would be 6 cupcakes left over.

For the cookies, the square root of 180 is approximately 13.42. So, you can arrange 13 cookies in a row and a column to form a nearly square array with 169 cookies, and there would be 11 cookies left over.

Therefore, the table with cookies allows more square arrangements than the one with cupcakes.

Answer:

a grapefruit would cost $0.06  and an orange would cost $0.05

Step-by-step explanation:

The price of an orange is 0.5 dollars and price of a grape is 0.6 dollars.

A linear equation has highest degree of a and contains two variables generally in x and y.

According to the given question you bought eight oranges and one grapefruit for a total of 4.60.

Let oranges be denoted by O and grapefruit be denoted by G.

∴ 8O + 1G = 4.60...(i)

Later that day, you bought six oranges and three grapefruits for a total of 4.80.

∴ 6O + 3G = 4.80...(ii)

Now multiplying (i) by 3 and subtracting it from (ii) to cancel out one variable and get the value of the other.

We get O = 0.5 dollars and G = 0.6 dollars.

Answer:

[tex]x \sqrt{1-9x^2} -3x \sqrt{1-x^2}[/tex]

Step-by-step explanation:

Since we have to analyze the cosine of an addition of angles, let's recall that cos of an addition is:

[tex]cos (\alpha +\beta ) = cos(\alpha ) cos(\beta) - sin(\alpha) sin(\beta)[/tex]

Let's also use those Greek letters [tex]\alpha[/tex] and [tex]\alpha[/tex] to represent the inverse functions we are dealing with:

[tex]\alpha =arcsin(3x)[/tex] and therefore, [tex]sin(\alpha ) = 3x[/tex]

[tex]\beta =arccos(x)[/tex] and therefore [tex]cos(\beta ) = x[/tex]

Now use these identities to re-write the equation for the cos of an addition given above:

[tex]cos (\alpha +\beta ) = cos(\alpha ) cos(\beta) - sin(\alpha) sin(\beta)\\cos (\alpha +\beta ) = cos(\alpha ) x - 3x sin(\beta )[/tex]

Now recall that the sine of an angle can be written in terms of the cos of the same angle via the Pythagorean identity: [tex]sin(\beta ) = \sqrt{1-cos^2(\beta) }[/tex]

In our case, and with our particular values, this gives:

[tex]sin(\beta ) = \sqrt{1-cos^2(\beta)} = \sqrt{1-x^2}[/tex]

Similarly we can write the cos of an angle in terms of the sine of the same angle:

[tex]cos(\alpha ) = \sqrt{1-sin^2(\alpha) }[/tex]

In ours case, using our values, this gives:

[tex]cos(\alpha ) = \sqrt{1-sin^2(\alpha) }= \sqrt{1-(3x)^2}= \sqrt{1-9x^2}[/tex]

So replacing these in the cos of an addition of angles formula, we obtain that the given expression equals:

[tex]x \sqrt{1-9x^2} -3x \sqrt{1-x^2}[/tex]

We can simplify the expression cos(arcsin(3x) + arccos(x)) in terms of x without trigonometric functions by using sin(arccos(x)) = sqrt(1 - x^2). The simplified expression is sqrt(1 - (3x)^2) * x - 3x * sqrt(1 - x^2).

To simplify the expression cos(arcsin(3x) + arccos(x)) in terms of x without trigonometric functions, we can use the fact that sin(arccos(x)) = sqrt(1 - x^2). Let's start by finding sin(arccos(x)).

arccos(x) gives us an angle whose cosine is x. We can then take the sine of this angle to get sin(arccos(x)). We know that sin^2(arccos(x)) + cos^2(arccos(x)) = 1, so sin(arccos(x)) = sqrt(1 - x^2).

Now, let's substitute the values in the original expression:

cos(arcsin(3x) + arccos(x)) = cos(arcsin(3x)) * cos(arccos(x)) - sin(arcsin(3x)) * sin(arccos(x))

Substituting the values, we have: cos(arcsin(3x)) * cos(arccos(x)) - sin(arcsin(3x)) * sin(arccos(x)) = sqrt(1 - (3x)^2) * x - 3x * sqrt(1 - x^2)

This is the simplified expression of cos(arcsin(3x) + arccos(x)) in terms of x without trigonometric functions.

Answer:

If Hunter is right beneath Graham ( 18ft-5ft=13ft) and G's arms are 18ft above ground ( and going up, no bending) the question would be at what hight would Graham catch the ball and and how soon.

The maximum hight that the ball can reach before falling ( when the vector F - force of throwing the ball to Graham, would be equal in module to gravitational force - considering gravitational velocity of 13ft/s^2

The equation of Graham cable is h(t) = -16t² + 1.5t + 18

The equation of Hunter ball is h(t) = -16t² + 24t + 5

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Now, The height of a projectile at time t is:

h(t) = -16t² + ut + h'

Where u is the initial velocity and h' is the initial height.

So, the equation of Graham cable is:

h(t) = -16t² + 1.5t + 18

and, the equation of Hunter ball is:

h(t) = -16t² + 24t + 5

[tex]\frac{3 meters}{1 second} * 24 seconds[/tex]

[tex]72 meters[/tex]

The total change in the tram's elevation is found by multiplying the speed (3 meters per second) by the time (24 seconds) which gives us a result of 72 meters.

The total change in the tram's elevation can be found using the formula for distance travelled which is speed times time. We know that the speed of the tram is 3 meters per second, and it moved for 24 seconds. To find the total distance travelled or the total change in elevation, we simply multiply the speed by the time.

So, 3 meters per second multiplied by 24 seconds equals 72 meters. Therefore, the total change in the tram's elevation was 72 meters.

Answer:

The slope would be -1

Step-by-step explanation:

The reason for this is that parallel lines will always go in the same direction, just from different locations. So in this case, we do not need to find the position of the line r but the slope. If line r's slope was different, they would intersect at some point and it wouldn't be parallel any more.

In geometry, parallel lines have the same slope. Therefore, if line q has a slope of -1, then a line r that is parallel to line q will also have a slope of -1.

The principle in geometry is that lines that are parallel have the same slope. The slope is a measure of the steepness of a line and it remains consistent all along the straight line. This is illustrated when you plot the line on a graph with x on the horizontal axis and y on the vertical axis. If a point where the line intersects the y-axis is considered, known as the y-intercept, the slope of the line remains the same irrespective of where along the line you measure it.

Now, you're dealing with a line q with a slope of -1. When drawing another line, say line r, and you want it parallel to line q, then it would have the same slope as line q. Hence, the slope of line r is also -1.

Step-by-step explanation:

*instead of doing a bunch of subtraction make it +(-#) you'll see what i mean

3(x - 3) - (6x - 3) = 4(3)

first do distributive property and figure out the easy stuff:

3x+(-9)+(-6x)+3=12

then you add 3x and 6x while also adding 9+3

-3x+(-6)=12

add +6 to both sides

-3x=18

then divide by -3

x=-6

Hey there!

3(x - 3) - (6x - 3) = 4(3)

3(x) + 3(-3) - 1(6x -3) = 4(3)

3(x) + 3(-3) -1(6x) -1(-3) = 4(3)

3x - 9 - 6x + 3 = 4(3)

-3x - 6 = 12

ADD 6 to BOTH SIDES

-3x - 6 + 6 = 12 + 6

CANCEL out: -6 + 6 because that gives you 0

KEEP: 12 + 6 because it helps solve for the x-value

-3x = 12 + 6

-3x = 18

DIVIDE -3 to BOTH SIDES

-3x/-3 = 18/-3

CANCEL out: -3/-3 because that gives you 1

KEEP: 18/-3 because it gives you the result of the x-value

x = 18/-3

18/-3 = x

SIMPLIFY IT!

x = -6

Therefore, your answer is: x = -6

Step-by-step explanation:

The statements that are true about the linear equation are:

The graph of a linear equation is a line. The line is made up of all points that satisfy the equation. To find the points that satisfy the equation, we can substitute different values for x and solve for y.

If we substitute x=1, we get y=4(1)−3=1. So, the point (1, 1) is on the graph of the equation.

If we substitute x=0, we get y=4(0)−3=−3. So, the point (0, −3) is also on the graph of the equation.

The graph of the equation is a line that passes through the points (1, 1) and (0, −3).
