C. 1.5, 2, and 2,5
D. 30, 40, and 50

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

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.

Answer:

30 cups of flour

Step-by-step explanation:

For every 12 cookies you need 4 cups of flour, which represents 1 batch of cookies. You want to figure out how many batches there are in 90 cookies. To do this you divide the total amount of cookies by the number of cookies in a batch.

90 cookies total/12 cookies/batch = 7.5 batches of cookies.

For each batch you need 4 cups of flour so you multiple the number of batches by the number of cups of flour.

7.5 batchs * 4 cups/batch = 30 cups of flour

so you need 30 cups of flour to make 90 cookies

Answer:

b) 8 packages

Step-by-step explanation:

Number of package = Total pounds ÷ weight of one package

                                 = 6 ÷ 0.75

                                 [tex]= \frac{6*100}{0.75*100}\\\\= \frac{600}{75}\\\\= 8[/tex]

Answer:

$11,025

Step-by-step explanation:

April: 150hrs

May-August: 200hrs x 4 = 800 hrs

September: 100 hrs

$10.50/hr pay rate

150+800+100 = $1,050

$1,050 x $10.50 = $11,025

*Gross pay is the amount of money made before tax

60, 100 = 300

Step-by-step explanation:

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

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:

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.

Answer:

The mean number is 10.8

Step-by-step explanation:

Since the mean number is the average of all numbers divided by how many there are, then 8+14+18+6+8=54. 54 divided by 5 equals 10.8.

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$

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.

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

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

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, the graph of option B is the graph of y=sin(0.5x) as it has the period of [tex]4\pi\\[/tex].
