Answer:

10.50p+15≤65

p≤ 100/21

Step-by-step explanation:

Let p represent pounds of Pumpkin Spice coffee.

We have been given that Lydia is at a coffee shop and knows she can spend no more than $65 before tax. She sees this price list in the coffee shop.

Item Price per pound

Dark Roast Coffee

$7.50

Pumpkin Spice Coffee

$10.50

Breakfast Tea

$23.50

Lydia wants to buy 2 pounds of Dark Roast coffee, so the cost of 2 pounds of Dark Roast coffee would be $7.50×2=$15 .

We are told that cost of each pound of Pumpkin Spice coffee is 10.50,socostof′ p'

pounds of Pumpkin Spice coffee would be 10.50

Since Lydia can spend no more than $65 before tax, so the cost of 2 pounds of Dark Roast coffee and 'p' pounds of Pumpkin Spice coffee must be less than or equal to 65.

We can represent this information in an inequality as:

10.50p+15≤65

Therefore, our required inequality would be 10.50p+15≤65

10.50+15-15≤65-75

10.50≤50

Divide both sides by 10.50:

10.50p/10.50 ≤ 50/10.50

P ≤ 50*2/10.50*2

P ≤ 100/21

P ≤ 4.76190

Therefore, Lydia can buy less than or equal to 100/21 pounds of Pumpkin Spice coffee.

In order to determine the amount of radium after 800 years, use the following formula:

where,

N: amount of radium after t years = ?

No: initial amount of radium = 50g

λ: decay constant

t = 800

The decay constant is calculated by using the following expression:

where t1/2 = 1960 is the half-life.

Now, by replacing λ, No and t = 800 you obtain:

Hence, after 800 years there are approximately 37.68g of uranium

Answer:

She ended up with fewer apples by buying the bigger bags.

Explanation:

The total weight of 2 bags of apples weighing 314 pounds each is equal to:

2 x 314 = 628 pounds

At the same way, the total weight of 3 bags weighing 223 pounds each is:

3 x 225 = 675 pounds

Since 628 pounds is less than 675 pounds, Marlene ended up with fewer apples by buying the bigger bags

Equation of a parabola is given by the equation

Where (h, h) are the coordinates of the vertex.

From the question given, the vertex is (2, 0)

So, h = 2, k = 0.

The y-intercept is given as (0, 12).

So, this means that x = 0 and y = 12

Substituting the values for h, k, x and y into the equation we have

Now, let's substitute the value of a into the equation to get equation for the parabola.

This becomes

AA (or AAA) or Angle-Angle Similarity

If any two angles of a triangle are equal to any two angles of another triangle, then the two triangles are similar to each other.

We do not have 3 angles.

SAS or Side-Angle-Side Similarity

If the two sides of a triangle are in the same proportion of the two sides of another triangle, and the angle inscribed by the two sides in both the triangle are equal, then two triangles are said to be similar.

We have two sides and 1 angle. But, two sides of a triangle are not in the same proportion of the two sides of another triangle

SSS or Side-Side-Side Similarity

If all the three sides of a triangle are in proportion to the three sides of another triangle, then the two triangles are similar.

The secant function is the reciprocal of the cosine function.

We can evaluate trigonometric functions of angles outside the first quadrant using reference angles as we have already done with the sine and cosine functions. The procedure is the same:

Find the reference angle formed by the terminal side of the given angle with the horizontal axis. The trigonometric function values for the original angle will be the same as those for the reference angle, except for the positive or negative sign, which is determined by x– and y-values in the original quadrant. (Figure) shows which functions are positive in which quadrant.

An even function is one in which f(-x) = f(x)

An even function is one in which f(-x) = - f(x)

Cosine and secant are even:

Therefore from the drop down the correct answer : secant function is EVEN

The value of the functions are;

(f. g)(x) =  9x² + 5

A function can be defined as a law, rule or expression showing the elaborate relationship between two variables in an expression or equation.

The variables are;

Given the functions;

To determine  (f .g)(x), we substitute the value of g(x) as x  in the function, we have;

(g)(x) = (3x)² + 5

Answer:

x = 3

Step-by-step explanation:

When twenty is reduced by one-third of a number, the result is 19. Find the number.

20 - 1/3x = 19

subtract 20 to both sides:

20 - 1/3x - 20 = 19 - 20

-1/3x = -1

multiply both sides by -3:

-3(-1/3x) = -1(-3)

x = 3

1. Using the order of mathematical operations, the values in brackets are added and multiplied to a product of $4.50 as the total tax.

2. Using the distributive property to expand the expression, 0.05(50 + 40) is  0.05 x 50 +  0.05 x40.

3. The total tax using the expanded expression is $4.50, the same product as when evaluating the original mathematical expression.

4. The original expression involves finding the total cost first before calculating the tax on the total.

The following is the order of mathematical operations:

1) The original expression, 0.05(50 + 40):

= 0.05 x 90

= 4.5

= $4.50

2) The expanded expression, 0.05(50 + 40)

=  0.05 x 50 +  0.05 x40

= 2.5 + 2.0

= 4.5

= $4.50

A trend line is also referred to as a line of best fit and it can be defined as a statistical or analytical tool that is commonly used in conjunction with a scatter plot, in order to determine whether or not there's any association (correlation) between data points.

In Mathematics, there are different types of trend line and these include the following:

When we have a binomial at the power of a number, of the form:

We use Pascal's triangle to determine the expansion. Pascal's triangle is the following:

Each row can be used to calculate a specific power, in our case the binomial is at the power of three, and we will use the 4rth row to expand, that is:

As you can see, the numbers that accompany a & b are the ones found in the 4th row of Pascal's triangle. We also see that the "degree" o the expansion always sums 3, that is a^3 has an overall degree of 3, a^2b has an overall degree of 3, ab^2 has an overall degree of 3 & b^3 has an overall degree of 3.

Answer: True.

Answer:

y= -2x -7

Step-by-step explanation:

The equation of a line in slope-intercept form is given by y= mx +c.

Given that the slope is -2, we can substitute m= -2 into the equation.

y= -2x +c

The value of c can be found by substituting a point in which the line passes through into the equation. In this case, the point is (-4, 1).

y= -2x +c

When x= -4, y= 1,

1= -2(-4) +c

1= 8 +c

Subtract 8 on both sides:

c= 1 -8

c= -7

Substituting c= -7 into the equation:

y= -2x -7

Optional step:

To check our answer, we can substitute one coordinate and see if the other coordinate is the same as the given coordinate. For example, let's substitute the x-coordinate of -4 into the equation.

y= -2(-4) -7

y= 8 -7

y= 1

Since the y-coordinate is indeed 1, the equation above is correct.

Answer: The new ratio of blue to yellow dye in its simplest form is 8/5.

Step-by-step explanation:

Blue and yellow dyes are mixed in an 8: 3 ratio to make 44 liters of a green-colored dye. A further 8 liters of yellow dye are added to the mixture. What is the new ratio of blue to yellow dye in its simplest form?

What is the Ratio?

The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.

Calculating the fraction of blue and yellow in the green dye,

Blue dye = 8/(3+8) * 44

Blue dye = 8/11 * 44

Blue dye = 32 liters

Similarly,

yellow dye = 3/11*44

yellow dye = 12

Now

Blue dye + yellow dye = 32+12 = 44

Now yellow dye is increased by 8 liters

the new volume fraction of yellow dye = 12+8

= 20

a fraction of blue dye remains the same,

the ratio of blue dye to new yellow dye in teal color.

= 32/20

=8/5

Thus, the new ratio of blue to yellow dye in its simplest form is 8/5.

We are given the following series

-6, -2, 2, 6

Common difference = last term - first term

For the first two terms

The common difference is calculated as

Last term - first term

Last term = -2

First term = -6

Common difference = -2 - (-6)

= -2 + 6

common difference = 4

Common difference = 2 - (-2)

common difference = 2 + 2

Common difference = 4

Last two terms

common difference = 6 - 2

Common difference = 4

The common difference for this sequence is 4

The sequence is arithmetic.

The solution to the system is the intersection of the graphs.

From the problem, the intersection is at (-3, 2)

The answer is (-3, 2)
