Answer:

7.65

Step-by-step explanation:

The total cost for 8 is 20.40, so you want to find what the cost for one panel is by dividing the total cost by the amount, which would be 20.40/8=2.55 then you want to know how much 3 of them cost, to find that you just multiply the cost of one of them by three, which would be 7.65

what’s x


100 points

Answers

Answer:

x = 1/8

Step-by-step explanation:

Add 6x to both sides:

3 + 2x = -6x + 4

3 + 8x = 4

Subtract 3 from both sides:

8x = 1

Divide each side by 8:

x = 1/8

So, x = 1/8

Riley rakes 1/6 of a lawn in 2/3 hour. How many lawns can Riley rake per hour?

Answers

Answer:

Riley rakes 1/4 of the lawns per hour.

Step-by-step explanation:

It is given that,

Riley rakes 1/6 of a lawn in 2/3 hour.

We need to find how many lawns can Riley rake per hour.

In 2/3 hour Riley rakes 1/6 of a lawn

In 1 hour Riley rakes [tex]\dfrac{1}{6}\times \dfrac{3}{2}=0.25[/tex] = 1/4 of a lawn.

Hence, Riley rakes 1/4 of the lawns per hour.

Answers

Assume that the budget is n.

Now we are given that 120% of the budget is equal to $60.

This means that:

60 = 1.2n

Solve the equation for n to know the budget:

60 = 1.2n

n = 60 / 1.2 = 50

Based on the above calculations, Jada's budget is 50$

What is the image of -1,-4 after a reflection over the x axis

Answers

answer: the image is (-1,4)

The image of the point after the reflection over x axis is P' ( -1 , 4 )

What is Reflection?

Reflection is a type of transformation that flips a shape along a line of reflection, also known as a mirror line, such that each point is at the same distance from the mirror line as its mirrored point. The line of reflection is the line that a figure is reflected over. If a point is on the line of reflection then the image is the same as the pre-image. Images are always congruent to pre-images.

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Given data ,

Let the point be represented as P

Now , the coordinates of the point P is P ( -1 , -4 )

The point P is reflected over the line x axis ,

So , when you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse.

Substituting the values in the equation , we get

The image of the reflected point is P' ( -1 , - ( -4 ) )

The image of the reflected point is P' ( -1 , 4 )

Hence , the reflected point is P' ( -1 , 4 )

Answer:

y = -5/2x + 7

Step-by-step explanation:

The line is perpendicular, so mx is the reciprocal of 2/5 which would be -5/2. Then you plug that and (4, -3) into the equation y = mx + b, which will come out as -3 = (-5/2)(4) + b. Multiply mx to get -3 = -10 + b. Add 10 to both sides to get 7 = b. Plug in mx and b into the equation and you have your answer.

A ball is shot upward such that its height (in feet) above the ground after t seconds is h(t) = -16t2 + 96t + 5. What is the ball's maximum height?​

Answers

Answer:

149 feet

Step-by-step explanation:

you have a quadratic equation and you need to fid it's vertex because that is the max height

h(t)= -16t² +96t +5

the x coordinate of the vertex is x= -b/2a for f(x)= ax²+bx+c so in our case

x=  [tex]\frac{-96}{2*(-16)}[/tex]= 3 , now we know that the vertex bbelongs to the graph so should verify the equation so we substitute t of the value of x=3 to find y

y= -16*3²+96*3+5= -144+288+5=149

the max height is the coordinate of y because it tels us how much it went up

Which of the following is the graph of y = sin(0.5x)?

Answers

The graph of option B is the graph of y=sin(0.5x).

Period of sin graph

The formula to find the period of the graph of sin(bx) is [tex]P=\dfrac{2\pi}{b}[/tex]

How to find the graph?

Use the formula [tex]P=\dfrac{2\pi}{b}[/tex] in order to find the graph of y=sin(0.5x) where we will substitute b=0.5.

We will get,

[tex]P=\dfrac{2\pi}{0.5}\\P=\dfrac{20\pi}{5}\\\\P=4\pi[/tex]

Here the period of the graph y=sin(0.5x) is [tex]4\pi\\[/tex].

So you have 21 people that you want to have meet in groups of 3. How many rounds of meeting would it take to have them all meet?

Answers

Answer:

1330 rounds of meetings

Step-by-step explanation:

You have a total of 21 people, and  they all want to meet with each other in groups of 3. This means we are dealing with a combination problem, where combination is the selection of items in which order does not matter.

Formula for combination:

ₙCᵣ = [tex]\frac{n!}{r!(n-r)!}[/tex]

where n is the total number of objects (in this case, total number of people: 21), and r is the sample set (in this case, groups: 3).

We plug in and get:

-> [tex]\frac{21!}{3!(21-3)!}[/tex]

-> 1330 different meetings for everyone to meet with each other in groups of 3.
