Answer: The water fountain shoots water from a height of 6 ft.

Step-by-step explanation: When looking at a Quadratic Function on a graph it looks like a U (this one would be a upside down U).  The top of that U is the Vertex. (keep in mind the question revolves around the X-Intersect)

A water droplet reaches its maximum height after 6 s IS WRONG

Talking about the VERTEX

It takes 6 s for a water droplet to rise and fall back to the ground IS WRONG

This is talking about the WHOLE Parabola

A water droplet reaches a maximum height of 6 ft. IS WRONG

This is also talking about the VERTEX

Answer:

396.5cm or 3.965m

Step-by-step explanation:

A sculptor is designing her new triangular masterpiece. In her scale​ drawing,

Scale Drawing

The shortest side = 9cm

The longest side = 37cm

Actual Drawing

The longest side of the actual triangular piece= 16.3m long.

We convert from meter to cm

1m = 100cm

16.3m =

Cross Multiply

= 16.3 m × 100cm/m

= 1630cm

How long will the shortest side of this piece​ be?

Let the shortest side be represented by x

9/37 = x/1630

Cross Multiply

37x = 9 × 1630

x = 9 × 1630/37

x = 396.48648649cm

≈ 396.5cm

Or converting to meter

= 396.5cm/100

= 3.965m

Step-by-step explanation:

let us start with

Molly's equation

15x + 10 = 100

solving for x we have

15x=100-10

15x=90

x=90/15

x=6

Maddie's equation

15x - 10 = 100

solving for x we have

15x=100+10

15x=120

x=120/15

x=8

well, from the solution niether of them is correct

Answer:

150

Step-by-step explanation:

Anagha's mother bought an equal number of ladoos and pedas. Let there are x number of ladoos and pedas.

She puts x/3 of the ladoos and x/5 of the pedas into a packet and gave it to Anagha to distribute at school.

Total no of sweets in the packet = 80

[tex]\dfrac{x}{3}+\dfrac{x}{5}=80\\\\\dfrac{5x+3x}{15}=80\\\\\dfrac{8x}{15}=80\\\\x=\dfrac{80\times 15}{8}\\\\x=150[/tex]

So, there are 150 ladoos brought by Anagha's mother.

I misread the question. Had the elementary row operations been represented by -3R2 + 4R1, then the answer would have been,

Answer:

around 28% of americans are obese

Step-by-step explanation:

The relative frequency of obesity according to this poll is 28 percent.

Relative frequency is the ratio of the considered sub group's count to the total count. (so its frequency of the considered sub group relative to the total frequency).

Suppose you've to calculate the joint relative frequency of a certain category out of the given big category.

Then its the ratio of the frequency of that certain category to the total frequency of that big category.

Given According to a recent poll 4060 out of 14500 people in the United States were classified as obese based on their body mass index .

Therefore, the relative frequency of obesity according to this poll is 28 percent.

Answer:

a)the weekly profit as a function of price is[tex]P=-10 p^2 + 600 p - 6500[/tex]

b) a bottle of wine be sold at $30 to realise maximum profit

c) the maximum profit that can be made by the producer is $2500

Step-by-step explanation:

The weekly demand curve of a local wine producer is p= 50-0.1q

p = price

q = quantity

Revenue function R =Price \times Quantity

R=(50-0.1q)q

[tex]R=50q-0.1q^2[/tex]

Cost function: c= 1500+ 10q

Profit function=R(x)-C(x)

Profit function= [tex]50q-0.1q^2-1500-10q[/tex]

Profit function= [tex]40q-0.1q^2-1500[/tex]   ----1

We have q = 500 - 10 p using p = 50 − 0.1q

[tex]P=-0.1 (500 - 10 p)^2 + 40 (500 - 10 p)- 1500\\P= -10 p^2 + 600 p - 6500[/tex]

General quadratic equation:[tex]ax^2+bx+c=0[/tex]

On comparing

a = -0.1 , b = 40 , c = -1500

Maximum Profit is at q = [tex]\frac{-b}{2a}=\frac{-40}{2(-0.1)}=200[/tex]

To find price must a bottle of wine be sold to realise maximum profit

p= 50-0.1q

p= 50-0.1(200)=30

Substitute the value of q in profit function(1) get the maximum profit

So, Profit function= [tex]40\left(200\right)-0.1\left(200\right)^{2}-1500=2500[/tex]

Hence

a)the weekly profit as a function of price is[tex]P=-10 p^2 + 600 p - 6500[/tex]

b) a bottle of wine be sold at $30 to realise maximum profit

c) the maximum profit that can be made by the producer is $2500

Answer:

B) 5 people share 27 brownies.

Step-by-step explanation:

This is the answer because:

1) If 5 people are sharing 27 brownies, it means they are basically asking, how many brownies did each person get. Then, we would write the numerical sentence: 27 ÷ 5 because we want to know how many brownies each person got.

Answer:

$0.68 per pound

Step-by-step explanation:

The price of sugar is $0.68 per pound.

A ratio indicates the number of times one number contains another.

Given that, the person paid $8.16 for 12 pounds of sugar.

Therefore, mathematically it can be written as:

12 pounds of sugar = $8.16

1 pound of sugar = $(8.16/12)

1 pound of sugar = $0.68

Hence, the price of sugar is $0.68 per pound.

Answer:

n = -5

Step-by-step explanation:

n - 4 = 3n + 6

n = 3n + 10

-2n = 10

n = -5

Answer:

-5

Step-by-step explanation:

Lets start by combining some common terms. -4 can be brought over to the right as +4 and 3n can be brought to the left as -3n to make the statement -3n +n = 6+4

Simplifying that, we get -2n = 10

Dividing 10 by -2, we get n = -5

Answer:

Answer:

1) 110*,     2) 84*,       3) 80*

Step-by-step explanation:

         These are intersected parallel lines (with only 1 intersecting line), so having missing angles in the questions 1 and 2 opposite from the shown angle is giving the answer away. However, on answer 3, it is on the same side, so for that angle you will need to subtract the angle of the intersecting line by 100* to get 80*. Check by adding the two. 100* + 80* = 180*.
