Substitute 0 for y and solve
1.5x + 4.5y = 18
1.5x + (4.5)(0) = 18
1.5x = 18
x = 18/1.5
x = 12

Substitute 0 for x and solve
1.5x + 4.5y = 18

helen buys two pineapples she pays with a £5 note and gets £3.60 change work out the cost of one pineapple

Answers

Answer:

Each pineapple costs £0.70.

Step-by-step explanation:

Let P be the number of pineapples Helen purchased and C the cost per pineapple, in £.

Helen's total cost would be:  P*C = total cost.

The total cost is the difference between £5 and £3.60, which is  £1.40.

We are given P (the number of pineapples, 2) and the total cost (£1.40) , so enter those numbers in the equation:

P*C = total cost

2*C = £1.40

C = £0.70

What is an arithmetic sequence?

It is a sequence of values in which the difference between consecutive terms is constant and is called common difference d.

The nth term of an arithmetic sequence is given by the rule presented as follows:

[tex]a_n = a_1 + (n - 1)d[/tex]

In which [tex]a_1[/tex] is the first term of the sequence.

An arithmetic sequence can also be defined recursively, as follows:

[tex]f(1) = a_1[/tex]f(n + 1) = f(n) + d.

In this problem, the sequence is given as follows:

a box has a width of 15 inches and a length of 16 inches. the volume of the box is increasing at a rate of 569 cubic inches per second, with the width and length being held constant. what is the rate of change, in inches per second, of the height when the height is 6 inches?

Answers

The rate of change in height when height is 6 inches is 2.37 inches per second approximately.

We know that the volume of cube with length L, width W and height H is given by,

V = L*B*H

So given that the length is 15 inches

the width is 16 inches

Let the height be h inches.

So now the volume is given by,

V = 15*16*h

Differentiating the volume with respect to time 't' we get,

dV/dt = 15*16 dh/dt

Now given that the rate of change in volume per second is 569 cubic inches.

So, dV/dt = 569

So, 15*16 dh/dt = 569

dh/dt = 569/(15*16) = 569/240 = 2.37 (approx)

So the rate of change in height is 2.37 inches approximately.

Find CT.

Answers

The length CT of the line segment is 38 units

How to determine the length of CT?

From the question, we have the following parameters

CJ = 9x + 1

JT = 2x + 15

Also, we understand that:

Point J is the midpoint of segment CT.

This means that

CJ = CT

So, we have

9x + 1 = 2x + 15

Evaluate the like terms

7x = 14

So, we have

x = 2

Length CT is calculated as

CT = 9x + 1 + 2x + 15

So, we have

CT = 9 x 2 + 1 + 2 x 2 + 15

(for estimate of p use 0.82)

Answers

The needed sample size is 1419. Sample Size is defined as the number of observations in the study.

In the question we have ,

estimate value of all voters who believe global warming ( p) = 82% = 0.82

margin of error (M.E) = 2% = 0.02

confidence of interval is calculated by estimate point value and add or subtract margin of error .

here,we have the value of confidence of interval is 95% = 0.95

Margin of error formula is

M.E = Z × √(p(1-p)/n)

where, p --> is estimated value

n---> sample size , which we required

Z ----> is z-value for observation

for the confidence of interval level 95% , the Z-value is 1.96 exist.

put all value in above formula we get,

0.02 = 1.96 × sqrt( ( 0.82)(1-0.82)/n)

=> 0.02 = 1.96× √(0.82×0.18/n)

= 0.02/1.96 = √0.1476/n => 0.000104= 0.1476/n

=> n = 1419

What is the general equation of a Straight line? How it represents a proportional relationship?

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

y = mx also represents direct proportionality. We can write [m] as -

m = y/x

OR

y₁/x₁ = y₂/x₂

We have Nick and Pam are paid $52.25 for their work. Nick worked 3.5 Hours, and Pam worked two hours. They split the money according to the amount of time each of them worked.

Assume that Nick recieved $[x]. Then, Pam will get - (52.25 - x). For direct proportionality -

y₁/x₁ = y₂/x₂

We can write -

x/3.5 = (52.25 - x)/2

2x = 3.5(52.25 - x)

2x = 182.875 - 3.5x

x = 33.25

find the vertex form

Answers

The vertex of the quadratic equations is at (1, -1), then the vertex form will be:

y = 4*(x - 1)^2 - 1

How to find the vertex form?

For a quadratic equation with leading coefficient a and a vertex (h, k), the vertex form is:

y = a*(x - h)^2 + k

And for a equation: y = a*x^2 + b*x + c

The x-value of the vertex is at:

h = -b/2a

In this case, we have:

y = 4x^2 - 8x + 3

So the x-value of the vertex is at:

h = -(-8)/2*4 = 1

To get the y-value we evaluate in x = 1

y = 4*1^2 - 8*1 + 3

y = 4 - 8 + 3 = -1

The vertex is at (1, -1) and the leading coefficient is 4, then the vertex form is:

Can anyone write the equation of the graph?

Answers

The equation of given graph is y = |x - 3| + 5.

The graph of a absolute or modulus function is a V- shape graph. The function of absolute is f(x) = |x|. The general form of absolute function is f(x)=a |x - h| + k. Where (h,k) is the vertex of graph.

Here, we can see that graph is in the form of V shape, so the function will be absolute function. Now, we have to find the vertex of graph.

As seen from the graph the minimum point on the graph is located at the point (3, 5) and the value of a should be 1.

So, by putting the value of vertex in general equation we get the equation of the graph,

y = |x - 3| + 5

Therefore, the equation of given graph is y = |x - 3| + 5.

The perimeter of the rectangle is  20 + 20√3 inches.

How to find the perimeter of a rectangle?

The perimeter of a rectangle is sum of the whole side of the rectangle. The side bounded by the rectangle is the perimeter of the rectangle.

Therefore,  the diagonal of the rectangle is given as 20 inches.

Using trigonometric ratios, let's find the sides of the rectangle.

sin 30 = opposite / hypotenuse

sin 30 = x / 20

x = 20 sin 30

x = 20 × 0.5

x = 10 inches

b² = 400 - 100

b = √300

b = √100 × 3

So from the property of similarity.

AB/XY = BC /YZ = CA/ ZX

Answers

The percent decrease in the travel time after getting a new job is 36%.

Percentage is defined as part of a whole expressed in hundredths or out of 100. It is usually written with the symbol "%".

First, determine the decrease in travel time after getting a new job by subtracting the new travel time of 30.72 minutes from the initial travel time of 48 minutes.

decrease in time = 48 - 30.72

decrease in time = 17.28

Then, determine the percent decrease by dividing the decrease in time of 17.28 minutes by the initial travel time of 48 minutes and multiply by 100.

Using the relation between standard deviation and variance it is concluded that the standard deviation for the population for the given variance is 7.1

What is the relation between standard deviation and sample variance?

In statistics, the two most crucial metrics are variance and standard deviation. While the variance is a measurement of how data points vary from the mean, standard deviation is a measure of the distribution of statistical data.

The square root of the variance yields the standard deviation, i.e.

Standard deviation = [tex]\sqrt{variance[/tex]

Given that sample, the variance is 49.7 and we have to calculate the standard deviation.
