Ricky bought flowers for Susan he spent a total of $14.85 and bought 13 flowers if you knows Lillys cost $1.25 and tulips cost $.90 how many of each flower did he buy Susan

Answers

Answer 1
Given:
Total amount spent = $14.85
Total number of flowers = 13
The cost of a lily = $1.25
The cost of a tulip = $0.90

Let x =  the number of lilies bought
Let y =  the number of tulips bought

Therefore
x + y = 13                             (1)
1.25x + 0.9y = 14.85           (2)

From (1),
y = 13 - x                             (3)
Substitute (3) into (2).
1.25x + 0.9(13 - x) = 14.85
0.35x + 11.7 = 14.85
0.35x = 3.15
x = 9
y = 13 -x = 4

Answer: 
9 lilies
4 tulips

Clara earns at least $36.75 but not more than $98 working. She earns $12.25 per hour. The number of hours it takes Clara to earn p dollars is modeled by a function. t(p)=p12.25 What is the practical range of the function?

Answers

The range of the function modelling the number of hours it takes clara to earn p dollars is;

A set of all real numbers from 3 to 8

Minimum dollars she earns working; p_min = $36.75

Maximum dollars she earns working; p_max = $98

number of hours it takes her to earn p dollars is given by;

t(p) = p/12.25

Now, range of a function is a set of all possible output values.

Thus, t(36.75) = 36.75/12.25

t(36.75) = 3 hours

Similarly;

t(98) = 98/12.25

t(98) = 8 hours

Since minimum time is now 3 hours and maximum time is now 8 hours, then the range of the function is;

3 ≤ t ≤ 8 which is a set of all real numbers from 3 to 8

John bought a used truck for $4,500. He made an agreement with the dealer to put $1,500 down and make payments of $350 for the next 10 months. The extra cost paid by taking this deal is equivalent to what actual yearly rate of interest?
A. 36%
B. 63%
C. 33%
D. 3.6%

Answers

first  the amount paid = $1500

So Making $350 for 10 months = 10*350 = $3500

Total amount paid is 1500 + 3500 = 5000

So the amount of $5000 was paid to cover the cost of $4500 within the 10 months

So you would get 33.
$350 for ten month is is $3500 
YOU already payed 1500

3500  and 1500  equals 5000

So  u paid $5000 to cover $4500 in 10 months

so it is 33% or C

Answers

The best way to answer this item is to use the Substitution method. Substitute the value of y from the first equation to the y of the second equation such that the second equation becomes,

     -4x + 3(x - 4) = -3

Simplifying the equation,
    -x = 9

Dividing both sides by -1 gives an answer of,
   x = -9

Then, substitute the value of x in the first equation.
    y = -9 - 4
    y = -13

What is the length of BE¯¯¯¯¯ ?


Answers

I hope it's not to late but the answer would be 81

Answer:

BE = 81

Step-by-step explanation:

From the graph we can see that point G is the barycentre of the triangle, because it's formed by the intersection of the three medians of the triangle, which are defined as segments from a vertex to the midpoint of the opposite side.

From the intersection of all triangle medians we have that:

[tex]BG=2GE[/tex]

[tex]CG=2GF[/tex]

[tex]AG=2GD[/tex]

Also, we know by hypothesis that [tex]GE=27[/tex]. Replacing this value:

[tex]BG=2GE[/tex]

[tex]BG=2(27)=54[/tex]

Then, by sum of segments, we have:

[tex]BE=BG+GE[/tex]

[tex]BE=54+27=81.[/tex]

Therefore, BE = 81.

The center of the circle is A( -3,3) and B(1,6) is on the circle. Find the area of the circle in terms of pie

Answers

We'll need to find the equation of this circle.  Once we have that equation, we use r to calculate the area.

The general equation of a circle with center at (h,k) and radius r is

(x-h)^2 + (y-k)^2 = r^2.  Subst. the given info (-3,3) [center] and (1,6) [point on circle], we get

(x+3)^2 + (y-3)^2 = r^2

(1+3)^2 + (6-3)^2 = r^2

16 + 9 = 25 = r^2

The area of this circle is A =pi(r^2).  But r^2 = 25.  So the area is

A = pi(25), or   A = 25pi.   Please note:  it's "pi," not "pie."

Find the slope m of the tangent to the curve y = 8 + 4x2 − 2x3 at the point where x =
a.

Answers

Final answer:

The slope m of the tangent to the curve y = 8 + 4x² - 2x³ at the point where x = a is found by taking the derivative of y with respect to x, which yields m = 8a - 6a².

Explanation:

To find the slope m of the tangent to the curve y = 8 + 4x² − 2x³ at the point where x = a, we first need to compute the derivative of the function y with respect to x. The derivative of a function at a particular point gives us the slope of the tangent line at that point.

The derivative of y with respect to x is given by:

dy/dx = d(8 + 4x² - 2x³)/dx = 8x - 6x²

To find the slope at x = a, we substitute a into the derivative:

m = 8a - 6a²

So, the slope of the tangent line at the point x = a on the given curve is m = 8a - 6a²

A triangle has vertices at L(2, 2), M(4, 4), and N(1, 6). The triangle is transformed according to the rule R0, 180°. Which statements are true regarding the transformation? Check all that apply. The rule for the transformation is (x, y) → (–x, –y). The coordinates of L' are (–2,–2). The coordinates of M' are (–4,4). The coordinates of N' are (6,–1). The coordinates of N' are (–1,–6).

Answers

A rotation of a point on the coordinate system for 180 degrees about the origin results in (x, y) → (-x, -y).

Given that the coordinate of L is (2, 2), then the coordinates of L' is (-2, -2).

Given that the coordinates of N is (1, 6), then the coordinate of N' is (-1. -6)

Therefore, the statements that are true regarding the transformation are:

The rule for the transformation is (x, y) → (–x, –y).

The coordinates of L' are (–2,–2).

The coordinates of N' are (–1,–6).

Transformation involves changing the coordinates of a shape

The true statements regarding the transformation are: (a), (b) and (e)

The transformation rule is given as: R0, 180°

This means 180 degrees rotation

A 180 degrees rotation is represented as: (x, y) → (–x, –y) --- option (a)

So, we have:

L'= (-2,-2) --- option (b)

M' = (-4,-4)

N = (-1,-6) -- option (e)

Hence, the true statements are: (a), (b) and (e)

) Why is the price system a more efficient system for allocating scarce resources than by authoritarian means, such as in command economies?

Answers

Prices and the ability to make a profit will increase the supply of the scarce resources, thereby lowering prices and increasing demand.

Step-by-step explanation:

Lets look at each of the options one by one:

Price System: In this system markets allocate resources through the price mechanism. An increase in demand raises price and encourages businesses to use more resources into the production of that good or service. In this system the government limits itself to protecting property rights of people and businesses using the legal system and protecting the value of money or the value of a currency.

Authoritarian System: In this system it is associated with a communist system. The scarce resources are owned by the government. The state allocates resources, and sets production targets and growth rates according to its own view of people's wants. They have their own idea of demand.

By comparing two systems it can be seen that Price System automatically moves resources to where they are most needed. So, price system is more efficient than authoritarian means.

Suppose that y varies inversely with x. Write an equation for the inverse variation. y = 4 when x = 6

Answers

Final answer:

The equation for the inverse variation is y = 24/x.

Explanation:

In an inverse variation, the equation can be represented as y = k/x, where k is a constant. To find the equation for the given scenario, we can substitute the values of y = 4 and x = 6 into the equation and solve for k.

4 = k/6

Cross-multiplying, we get k = 24. Therefore, the equation for the inverse variation is y = 24/x.

The largest part of landfills is made up of newspapers. A 30.48 cm stack of newspapers weighs about 15.87 kg. How many meters of newspapers are stacked up?

Answers

15.87kg x 1000g/kg = 15, 870g 
30.49cm x 1m/100cm = 0.3049m

The stack of newspapers is 0.3048 meters tall.

The student is asking how to convert the height of a stack of newspapers from centimeters to meters for a proper estimation of its volume in terms of the given weight. Since the question specifies a stack of newspapers that is 30.48 cm high and weighs 15.87 kg, we need to convert the height from centimeters to meters to find out how tall the stack is in meters.

To convert centimeters to meters, we divide the number of centimeters by 100, because there are 100 centimeters in a meter. Therefore:

30.48 cm / 100 = 0.3048 meters

So, the stack of newspapers is 0.3048 meters tall.
