Brad wants to buy flowers for his friend with $15. The daisies are $1 each and the roses are $3 each. He buys 3 more daisies than roses how much did the roses cost?

Answers

Answer 1
d + 3r = 15
d = r + 3

r + 3 + 3r = 15
4r + 3 = 15
4r = 15 - 3
4r = 12
r = 12/4
r = 3 ....he bought 3 roses, at $ 3 per rose = $ 9 <==

d = r + 3
d = 3 + 3
d = 6....he bought 6 daisies, at $ 1 per daisy = $ 6
Answer 2
Brad wants to buy flowers for his friend with $15. The daisies are $1 each and the roses are $3 each. He buys 3 more daisies than roses how much did the roses cost?
-daisies=x-      -roses=y-

x+y=15

the sentence how he buys 3 more daisies than roses so...
(y=x-3)
you then plug in the value of y in the equation to have only one variable...
x+ 3(x-3)=15
you then multiply 3 to the parenthesis...
x+3x-9=15
then add 9 on both sides...
4x=24
and then divide 4 on both sides...
x=6

if you plug the value of x(daisies) in the equation...
6+y=15
you subtract 6 on both sides and get...
y=9

you can also get the answer by solving for y with x...
y=3(x-3)
(x=6)
plug in x...
y=3(6-3)
y=3(3)
y=9
Answer: the roses cost $9

A substance with a density of 1.0 gram per cubic centimeter has a mass of 1.0 kilogram if its volume is 100 cubic centimeters. True or false ? Please answer with explanation

Answers

False!!!

Matteo is adjusting a satellite because he finds it is not focusing the incoming radio waves perfectly. The shape of his satellite can be modeled by y^2=6x where x and y are modeled in inches. He realizes that the static is a result of the feed antenna shifting slightly off the focus point. What is the focus point of the satellite? (–1.5, 0) (0, –1.5) (0, 1.5) (1.5, 0)

Answers

Answer: (1.5, 0)

Step-by-step explanation:

Given : The shape of his satellite can be modeled by [tex]y^2=6x[/tex] where x and y are modeled in inches.

Now,the given equation [tex]y^2=6x[/tex] is a equation of parabola.

Here, coefficient of x is positive, hence the parabola opens rightwards.

On comparing this equation with standard equation [tex]x^2=4mx[/tex], we get

[tex]4m=6\\\Rightarrow\ m=\frac{6}{4}=1.5[/tex]

In standard equation, coordinates of focus=(m,0)

Thus for given equation coordinates of focus=(1.5,0)

Each level of a smartphone app adds more gems for you to match. On level one, there were 13 gems. On level twelve, there were 123 gems. When you complete all twelve levels, how many total gems will you have matched?

Answers

First find the rate or common difference if it exists.

(123-13)/(12-1)

110/11

10  So this essentially form an arithmetic sequence because each term is a constant difference with respect to the previous term.

The sum of an arithmetic sequence, in simplest terms, is the average of the first and last terms times the number of terms, in this case:

(12-1+1)(13+123)/2

12(68)

816

So the player will have matched 816 gems in total for the twelves rounds.

There are 150 marigold plants in a back yard. Each month, the number of marigold plants decreases by 15%. There are 125 sunflower plants in the back yard. Each month, 8 sunflower plants are removed. Part A: Write functions to represent the number of marigold plants and the number of sunflower plants in the back yard throughout the months. (4 points) Part B: How many marigold plants are in the back yard after 3 months? How many sunflower plants are in the back yard after the same number of months? (2 points) Part C: After approximately how many months is the number of marigold plants and the number of sunflower plants the same? Justify your answer mathematically. (4 points)

Answers

Let us first assign variables. We say that:

X = number of marigold plants

Y = number of sunflower plants

n = number of months

We can see that in the given problem, X is decreasing by a percentage, this means that we have to set-up a geometric equation while for Y the decrease is linear so we set-up an arithmetic equation.

 

Part A.

For marigold plants X, a geometric sequence has a general form of:

X = Xo * (1 + r)^n

where r = -15% = -0.15   (negative since it is decreasing)

Xo = the initial amount of marigold plants = 150

X = 150 * (1 – 0.15)^n

X = 150 (0.85)^n

 

For the sunflower plants Y, an arithmetic sequence has a general form of:

Y = Yo + d * n

where d = -8 and Yo = 125

Y = 125 – 8 n

 

Part B. For n = 3

 

X = 150 (0.85)^3 = 92.12 = 92

 

Y = 125 – 8 (3) = 101

 

Part C. From Part B we see that the two values are very far from each other when n = 3, therefore they must be similar when n < 3. So we try n = 2

 

X = 150 (0.85)^2 = 108.38 = 108

 

Y = 125 – 8 (2) = 109

 

Therefore the two plants have approximately similar amount after 2 months.

Hi! 

(before I answer, I wanted to say that tagging me doesn't normally get my attention, and you won't always get the people you want to answer your question to answer it, whether you tag someone or not, because it doesn't notify anyone. Hope that makes sense.) :)

So first let's look at the graph. 

The y intercept is 6. 
That rules out A and B. 

The line is going down, which means the coefficient to x will be negative. 

That rules out C.

Now to make sure D is correct, find the slope of the line. 
The slope of the line is 3/4, which means D is correct.

The answer is y = 3/4x + 6

Hope this helps! :)
Since the line is going down, the gradient must be negative
After that,
Let A be a point on the line with coordinates (0,6) while let B be another point on the line with coordinates (8,0)
Let's recall the gradient formula
y1-y2/x1-x2
So, the gradient of AB will be 6-0/0-8= -3/4
Let's also recall that the formula of a linear line is y=mx+c, m is the gradient while x is the y-intercept.
So in this case, the gradient is -3/4 while the y-intercept is 6.
As such, the answer must be the third one, y=-3/4x + 6

Which rate is equivalent to the unit rate of 15 miles per gallon?

thirty miles over three gallons

sixty miles over four gallons

Answers

Sixty miles over four gallons would reduce down to 15 miles over one gallon which would 15 miles per gallon.

Answer:

Fourth option is correct.

Step-by-step explanation:

Since we have given that

thirty miles over three gallons  

Unit rate would be  miles per gallon.

three gallons over thirty miles  

Unit rate would be  miles per gallon.

four gallons over sixty miles  

Unit rate would be  miles per gallon.

sixty miles over four gallons

Unit rate would be  miles per gallon.

Hence, Fourth option is correct.

The Shake Shack sells large and small shakes. A large shake costs $5, and a small shake costs $3. On Sunday, the Shake Shack had a total revenue of $479. Which equation can be used to represent x, the number of small shakes sold and y, the number of large shakes sold?
479x + 479y = 15
4x + 4y = 479
5x + 3y = 479
3x + 5y = 479

Answers

Since X represents small shakes and y large ones The 3 must be with x and the 5 with y. The last equation is the only one that fits this criteria.

Answer: 3x + 5y = 479

Answer:

3x + 5y = 479

Step-by-step explanation:

As the problem states it, the number of small shakes will be represented by "x" and the number of large shakes will be represented by "y", so we know that the number of each mutiplied by the cost, its equal to the total revenue which is $479, so we just put that into an equation:

3x + 5y=$479

And that´s the equation that can be used to represent that inequality.
