The correct option is the fourth one, the slope and y-intercept are different.

Here we have the linear equation:

3x - 5y = 4

We know that it is dilated by a scale factor of 5/3, so let's find the dilation.

We can rewrite the linear equation as:

-5y = 4 - 3x

y =  (3/5)x - 4/5

Now let's apply the dilation:

y = (5/3)*[ (3/5)x - 4/5]

y = x - 4/3

Then we can see that the slope and the y-intercept are different, the correct option is 4.

The equations to represent each girl's shoppins spree is 3x + y = 38.0 and 4x + 3y = 71.50. Price of one shirt costs $8.50 and price of one pair of shorts costs $12.50.

Let x be the price of one shirt, and y be the price of one pair of shorts. Then, we can write the following system of equations

For Jazmin

3x + y = 38.0

For Justine

4x + 3y = 71.50

To solve for the price of one pair of shorts using elimination method, we need to eliminate one of the variables. We can do this by multiplying the first equation by 3 and the second equation by -1, and then adding them together

9x + 3y = 114.0

-4x - 3y = -71.50

5x = 42.50

x = 8.50

So, one shirt costs $8.50.

To find the price of one pair of shorts, we can substitute the value of x into either of the original equations and solve for y. Using the first equation

3(8.50) + y = 38.0

25.50 + y = 38.0

y = 12.50

Therefore, one pair of shorts costs $12.50.

Parallel cross sections of a sphere look like circles with the same radius as the sphere, while perpendicular cross sections look like points. Cross sections taken at other angles will be ellipses.

A sphere is a three-dimensional geometric shape that is perfectly round in shape, like a ball. It is defined as the set of all points in three-dimensional space that are at a constant distance (the radius) from a given point called the center.

If we take a cross section of a sphere, the resulting shape will depend on the angle at which the section is taken relative to the center of the sphere.

If we take a plane that is parallel to the base of the sphere, the cross section will be a circle with the same radius as the sphere. This is because the intersection of the plane with the sphere will be a circle, and since the plane is parallel to the base of the sphere, the circle will have the same radius as the sphere.

On the other hand, if we take a plane that is perpendicular to the base of the sphere, the cross section will be a point. This is because the plane will intersect the sphere at only one point, which is the point at which the plane is perpendicular to the sphere.

If we take a plane that is neither parallel nor perpendicular to the base of the sphere, the resulting cross section will be an ellipse. The size and shape of the ellipse will depend on the angle at which the plane intersects the sphere.

The value of c for the intersecting secants is derived to be equal to 2 cm

The intersecting secant theorem, also known as the secant-secant theorem, states that when two secant lines intersect outside a circle, the product of the length of one secant segment and its external segment is equal to the product of the length of the other secant segment and its external segment.

c × 18 cm = 3 cm × 12 cm

c18 cm = 36 cm²

c = 36 cm²/18 cm

In mathematics, an inequality is a mathematical statement that describes a relationship between two quantities that are not necessarily equal. An inequality can express that one quantity is less than, less than or equal to, greater than, greater than or equal to, or not equal to another quantity.

Inequalities can be represented using various symbols. For example, the symbol < represents "less than," the symbol > represents "greater than," the symbol ≤ represents "less than or equal to," and the symbol ≥ represents "greater than or equal to." The symbol ≠ represents "not equal to."

Inequalities are also used in algebra to solve equations and to represent the solution set of an equation. In this context, an inequality can represent all the possible values of a variable that satisfy the equation. For example, the inequality x > 5 represents all the values of x that make the expression x - 5 positive.

We can write an inequality to represent the number of points, m, obtained by Machelle on her exam:

m > 100 - 27

Simplifying this expression, we get:

m > 73

This means that Machelle must have scored more than 73 points on her exam. Based on the table, we can see that a score of more than 73 points corresponds to a grade of at least a D. Therefore, Machelle can get a grade of D or higher on her exam.

Answer: 100 times

Step-by-step explanation:

The cube is numbered 1 to 6. That is, 1, 2, 3, 4, 5, 6. That means there are 6 possible outcomes for each toss. But there are 2 outcomes we want, 5 and 6 (greater than 4).

So, for each toss, there is a probability of 2/6 = 1/3 that this will occur.

With 300 tosses, we can say that this will probably happen 300 times. This means that it will happen

1/3 * 300 times = 100 times.

Therefore, we can predict we will get a 5 or 6 about 100 times.

According to the information, the surface area of the prism is approximately 777.868 square inches, and its volume is approximately 3156.846 cubic inches.

Since the hexagonal bases are regular, we know that all the six triangles are congruent to each other.

Let's call the side length of the hexagon s. Then, the apothem of each triangular face is given as 9 inches, and the base of each triangular face is given as 10 inches. Using the Pythagorean theorem, we can calculate the side length of the hexagon as follows:

s^2 = (10/2)^2 + 9^2

s^2 = 25 + 81

s^2 = 106

s ≈ 10.2956 inches

The surface area of the prism can be calculated by adding up the areas of its faces. The hexagonal base has an area of:

A_base = (3√3/2) * s^2 ≈ 450.978 square inches

The area of each triangular face is:

A_tri = (1/2) * base * height = (1/2) * 10 * 9 = 45 square inches

So the total surface area of the prism is:

A_total = 2A_base + 6A_tri

A_total = 2(450.978) + 6(45)

A_total ≈ 777.868 square inches

The volume of the prism can be calculated by multiplying the area of the base by the height of the prism:

V = A_base * height

V = 450.978 * 7

V ≈ 3156.846 cubic inches

Therefore, the surface area of the prism is approximately 777.868 square inches, and its volume is approximately 3156.846 cubic inches.

Answer:

The answer is B) -35.16 grams per half-life cycle

It will take Emma about 4.04 years for her balance to reach $450, assuming she doesn't make any payments and the interest rate remains constant.

The formula that models this situation is P(1 + r/n)ⁿˣ, where P is the principal (the initial amount borrowed or invested), r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the time (in years) that the money is invested or borrowed.

In this case, the principal is $300, the annual interest rate is 15%, the interest is compounded monthly (so n = 12), and we want to find the time it takes for the balance to reach $450.

P = 300(1 + 0.15/12)¹²ˣ

To find out how long it will take for Emma's balance to reach $450, we need to solve for t in the equation above. We can do this by using logarithms to isolate the variable t:

=>  log(1.5) = 12t x log(1 + 0.15/12),

we can use the properties of logarithms. Specifically, we can use the property that log(a x b) = log(a) + log(b) to separate the logarithm on the right side of the equation:

log(1.5) = 12t x log(1 + 0.15/12)

log(1.5) = log[(1 + 0.15/12)¹²ˣ]   (using log(a x b) = log(a) + log(b))

Now we have two logarithms that are equal to each other. Therefore, we can take the exponential of both sides to eliminate the logarithms:

1.5 = (1 + 0.15/12)¹²ˣ

Simplifying this expression further, we get:

1.5 = (1.0125)¹²ˣ]

log(1.5) = log[(1.0125)¹²ˣ]]

log(1.5) = 12t x log(1.0125)

Finally, we can solve for t by dividing both sides by 12 x log(1.0125):

log(1.5) / [12 x log(1.0125)] = t

t ≈ 4.04

Therefore, the simplified expression is t ≈ 4.04.

Answer: To find the coordinates of F' and G', we need to reflect points F and G across the line y = 5, since point D is located on this line.

For point F, the y-coordinate changes from 11 to -1, since the distance between the line y = 5 and point F is 6 units (2 times the distance between D and the line). Therefore, the coordinates of F' are (3,-1).

For point G, the y-coordinate changes from 8 to 2, since the distance between the line y = 5 and point G is 3 units (1.5 times the distance between D and the line). Therefore, the coordinates of G' are (2,2).

Thus, the coordinates of F' are (3,-1) and the coordinates of G' are (2,2).

Cash paid for insurance during 2014 was $15,100.The following formula can be used to determine the cash spent on insurance in 2014:

Insurance expense in 2014 minus an increase in prepaid insurance = Cash paid for insurance.

The difference between the prepaid insurance balance at December 31, 2014, and December 31, 2013, can be used to compute the rise in prepaid insurance:

Prepaid insurance at December 31, 2014 minus Prepaid insurance at December 31, 2013 equals $1,500 minus $2,400, or -$900.

The fact that the prepaid insurance balance fell between 2013 and 2014 indicates that the business used more insurance coverage than it had purchased for the year. As a result, the 2014 insurance premiums paid in cash are:

Insurance expense for 2014 minus the increase in prepaid insurance is $14,200 - (-$900) = $15,100 in cash paid for insurance.

Knowing that t.05 = 1.812 when df = 10 helps us to determine the critical value of t for hypothesis testing in this scenario.

If we know that t.05 = 1.812 when df = 10, then it is correct to say that the critical value of t at the 5% significance level for a two-tailed test with 10 degrees of freedom is 1.812.

The t-distribution is a family of probability distributions that depend on the sample size and the degrees of freedom (df). The degrees of freedom represent the number of independent observations available to estimate the population parameters. In this case, when df = 10, the t-distribution has thicker tails compared to the standard normal distribution.

The value t.05 represents the critical value of t at the 5% significance level (or alpha level) in a two-tailed test. This means that if the calculated t-value falls outside the range of -t.05 to +t.05, then the null hypothesis can be rejected.

The cost to paint the room with two coats of paint is $48, using paint that costs $8 per gallon and covers 300 square feet per gallon.

To determine how much it costs to paint the room if the paint costs $8 a gallon and each gallon covers 300 square feet of wall, we first need to determine how many gallons of paint we need. From problem #18, we know that the room has a total wall area of 800 square feet, and we need to apply two coats of paint.

The total wall area that needs to be covered by paint is:

800 square feet x 2 coats = 1600 square feet

To determine how many gallons of paint we need, we divide the total square footage by the coverage of one gallon of paint:

1600 square feet ÷ 300 square feet/gallon = 5.33 gallons (rounded up to the nearest gallon)

Therefore, we need 6 gallons of paint to complete the job (since we can't purchase a fractional amount of a gallon).

The cost of the paint can now be calculated by multiplying the number of gallons of paint by the cost per gallon

6 gallons x $8/gallon = $48

Given that Area used a total of 7.2 pints of blue and white paint to paint her bedroom walls. And 1/4 of the amount is blue paint, then the remaining 3/4 of the amount must be white paint.

To find the amount of white paint used, we can use the following formula:

Amount of white paint = Total amount of paint - Amount of blue paint

Since we know that the total amount of paint used is 7.2 pints and 1/4 of that amount is blue paint, we can calculate the amount of blue paint as:

Amount of blue paint = (1/4) x 7.2 = 1.8 pints

the value of c is 11.165 lbs. This was calculated using the z-score formula, assuming a normal distribution with a mean weight of 10 lbs and a standard deviation of 0.5 lbs. This ensures that 99% of all parcels are at least 1 lb under the surcharge weight.

To find the value of c, we need to use the standard normal distribution and the z-score formula. Since we know that 99% of all parcels are at least 1 lb under the surcharge weight, we can use the z-score associated with the 99th percentile, which is 2.33 (from a z-score table).

The formula for the z-score is:

z = (x - μ) / σ

where x is the weight of the parcel, μ is the mean weight, and σ is the standard deviation.

In this case, we want to find the weight of the parcel that is at the 99th percentile, which is 1 lb under the surcharge weight. Let's call this weight x. We know that the surcharge weight is c, so the weight of the parcel that is 1 lb under the surcharge weight is (c - 1).

Using the z-score formula and substituting the values we know, we get:

2.33 = ((c - 1) - μ) / σ

We want to solve for c, so we need to rearrange the equation:

c - 1 = 2.33σ + μ
c = 2.33σ + μ + 1

We don't know the values of μ and σ, but we can use the fact that the distribution is normal to estimate them. We can assume that the distribution is centered at the mean weight of all parcels, and that the standard deviation is equal to the average difference between the weight of each parcel and the mean weight.

Let's say that the mean weight is 10 lbs, and the standard deviation is 0.5 lbs. Then, we can plug these values into the equation for c:

c = 2.33(0.5) + 10 + 1
c = 11.165

So, the value of c that ensures that 99% of all parcels are at least 1 lb under the surcharge weight is approximately 11.165 lbs.
