An item is regularly priced at $53. Joe bought it on sale for 10% off the regular price. How much did Joe pay?

Answer:

This is a guess but I think it's 5 min per table.

Step-by-step explanation:

The reason being:

if we know that she has 9 tables to get to and each table can seat 4 people, we would have to multiply both numbers to find how many TOTAL people are in the restaurant during the first few hours.

9x4 = 36 people in total

then, we need to convert 3hrs into minutes to get a more accurate rep as to how much time she would spend at each table (she isn't going to spend the entire 3 hrs with only one table now, is she?)

so for this, we convert 3hrs into minutes

1 min = 60 secs

1 hr = 60 minutes

3hrs -> 60 x 3 = 180 minutes

now, to understand how many time she spends at each table, we need to figure out by dividing the # of people by the amount of minutes.

180 minutes/36 people = 5 mins per table.

Therefore , the solution of the given problem of equation comes out to be slope of 1 and a y-intercept of -1, passing through the points (-3, -4) and (1, 0).

Complex algorithms frequently employ variable words to demonstrate coherence between two opposing assertions. Equations are academic expressions that are used to demonstrate the equality of different academic figures. In this case, leveling generates b + 7 rather than another algorithm that could analyze data provided by y + 7, split 12 into two parts, and create y + 7.

Here,

This linear relationship's expression can be found by first determining the slope using the following formula:

=> slope = (y-change) / (change in x)

=> slope = (2 - (-2)) / (4 - 0) = 4/4 = 1

Consequently, the line's inclination is 1. We can now determine the equation using the point-slope form of a line's equation:

=> y - y1 = m(x - x1)

where (x1, y1) is a location on the line and m denotes the slope. We have a choice between the two points provided, so let's use (0, -2):

=> y - (-2) = 1(x - 0)

=> y + 2 = x

By taking 2 away from both edges, we arrive at:

=> y = x - 2

slope = (0 - (-4)) / (1 - (-3)) = 4/4 = 1

=> y - y1 = m(x - x1)

=> y - (-4) = 1(x - (-3))

=> y + 4 = x + 3

=> y = x - 1

A line with a slope of 1 and a y-intercept of -1, passing through the points (-3, -4) and (1, 0), represents the graph of this linear connection.

Solving a system of equations we can see that they have 4 lizards and 5 spiders.

We know that each spider has 8 legs, and each lizard has 4 legs.

Now we can define the variables:

x = number of lizards.

y = number of spiders.

We know that the total number of animals is 9, so:

x + y = 9

And the total number of legs is 56, then we can write:

4x + 8y = 56

Then we have a little system of equations:

x + y = 9

4x + 8y = 56

We can isolate x in the first equation to get:

x = 9 - y

Replacing that in the other one, we wll get:

4*(9 - y) + 8y = 56

36 - 4y + 8y = 56

4y = 56 - 36

4y = 20

The answer of the given question based on the hypothesis the answer is the calculated t-value of -2.58 is less than the critical t-value of -2.009, we cannot reject the null hypothesis.

A hypothesis is an educated guess or prediction that is used to explain an observation or set of observations. It is a proposed explanation or possible answer to a research question or problem that is based on prior knowledge, experience, and research. In science, a hypothesis is often tested through experiments or observations to determine if it can be supported or rejected by the evidence.

Hypothesis:

The city of Goose Pimple, Vermont, hypothesizes that contracting with Grimms Health Maintenance Organization will result in a significant reduction in health care costs per employee.

Null Hypothesis:

The null hypothesis is that there is no significant difference in health care costs per employee between last year and this year with the contract with Grimms Health Maintenance Organization having no impact.

Evaluation:

To evaluate the hypothesis, we will perform a one-sample t-test. The test statistic is calculated as:

t = (sample mean - population mean) / (sample standard deviation / sqrt(sample size))

Assuming a significance level of 0.05, we will reject the null hypothesis if the calculated t-value is greater than the critical t-value.

Population mean = $3,261 (given)

Sample mean = $3,015

Sample standard deviation = $1,745

Sample size = 50

t = (3015 - 3261) / (1745 / sqrt(50)) = -2.58

Using a t-table with 49 degrees of freedom (sample size - 1) and a significance level of 0.05, the critical t-value is ±2.009.

Since the calculated t-value of -2.58 is less than the critical t-value of -2.009, we cannot reject the null hypothesis. This means that there is not enough evidence to suggest that there is a significant difference in health care costs per employee between last year and this year with the contract with Grimms Health Maintenance Organization having no impact.

The factory has 172 litres of dye available.

Liters (also spelled litres) is a unit of volume in the International System of Units (SI). It is commonly used to measure the volume of liquids, gases, and solids that can be poured or contained in a container. One liter is equivalent to 1000 cubic centimeters (cc) or milliliters (ml), and it is roughly equal to 1.057 quarts or 0.264 gallons.

In the given question,

First, we need to find out how much dye is needed for one roll of fabric. We know that 43 liters of dye are needed for 1 roll of fabric that is 1,067 feet long. Therefore, we can say that:

1 roll of fabric = 43 liters

1,067 feet

To find out how much dye is needed for 5 rolls of fabric, we can multiply both sides of this equation by 5:

5 rolls of fabric = 5 × 43 liters

1,067 feet = 215 liters

1,067 feet

So, 5 rolls of fabric would require 215 liters of dye.

Next, we need to check if the 4 buckets of dye are enough to dye 5 rolls of fabric. Each bucket contains 43 liters of dye, so 4 buckets would contain:

4 buckets of dye = 4 × 43 liters

= 172 liters

Therefore, the factory has 172 liters of dye available.

Since 215 liters of dye are required for 5 rolls of fabric, and the factory has only 172 liters of dye available, it cannot dye 5 rolls of fabric with the given amount of dye.

An approximate of 68% of American women have shoe sizes that are between 6.54 and 9.58.

To use the empirical rule, we need to assume that the distribution of women's shoe sizes is approximately normal. Given a mean of 8.06 and a standard deviation of 1.52, we can standardize the values of 6.54 and 9.58 by subtracting the mean and dividing by the standard deviation:

Ζ1 = (6.54 - 8.06) / 1.52

Ζ1 = -1.00

Ζ2 = (9.58 - 8.06) / 1.52

Ζ2 = 1.00

The standardized values tell us that the value of 6.54 is 1 standard deviation below the mean, while the value of 9.58 is 1 standard deviation above the mean. According to the empirical rule, about 68% of the data falls within one standard deviation of the mean. Therefore, we can say that: [tex]P(6.54 < x < 9.58) = P(-1.00 < z < 1.00) = 68%[/tex]

The measure of angle mLQ is 125°. we got the answer with the concept of  inscribed angle in the figure .

what is inscribed angle?

An inscribed angle is an angle formed by two chords in a circle that have a common endpoint on the circle. In other words, the endpoints of the angle are on the circle, and the angle "opens up" inside the circle. The measure of an inscribed angle is equal to half the measure of the arc that it intercepts.

In the given question,

We know that the measure of angle mWC is 108° and the measure of angle m/U is 37°. Since angle QCU is an inscribed angle that intercepts arc CQ, its measure is equal to half the measure of arc CQ. Similarly, angle LUW is an inscribed angle that intercepts arc WL, so its measure is equal to half the measure of arc WL.

We can use these facts to set up the following equation:

mLQ = (mCQ / 2) + (mWL / 2)

We can find the measures of arcs CQ and WL by subtracting the measures of angles QCU and LUW from 360°, respectively. Therefore:

mCQ = 360° - 2mQCU

= 360° - 2(mWC - m/U)

= 360° - 2(108° - 37°)

= 182°

mWL = 360° - 2mULW

= 360° - 2(m/U + mWC)

= 360° - 2(37° + 108°)

= 68°

Substituting these values into the equation for mLQ, we get:

mLQ = (mCQ / 2) + (mWL / 2)

= (182° / 2) + (68° / 2)

= 125°

Therefore, the measure of angle mLQ is 125°.

Answer:

Step-by-step explanation:

To find sin(alpha-beta), we can use the trigonometric identity:

sin(alpha - beta) = sin(alpha)cos(beta) - cos(alpha)sin(beta)

We are given that sin(alpha) = 11/12 in the second quadrant and cos(beta) = 15/17 in the fourth quadrant. We can use the Pythagorean theorem to find sin(beta):

sin^2(beta) + cos^2(beta) = 1

sin(beta) = sqrt(1 - cos^2(beta))

sin(beta) = sqrt(1 - (15/17)^2)

sin(beta) = sqrt(1 - 225/289)

sin(beta) = sqrt(64/289)

sin(beta) = 8/17 (since sin(beta) is positive in the fourth quadrant)

Now we can plug in the values we know into the identity:

sin(alpha - beta) = sin(alpha)cos(beta) - cos(alpha)sin(beta)

sin(alpha - beta) = (11/12)(15/17) - cos(alpha)(8/17)

We still need to find cos(alpha), which we can do using the Pythagorean identity:

sin^2(alpha) + cos^2(alpha) = 1

cos(alpha) = sqrt(1 - sin^2(alpha))

cos(alpha) = sqrt(1 - (11/12)^2)

cos(alpha) = sqrt(23/144)

Now we can substitute this value into the expression for sin(alpha - beta):

sin(alpha - beta) = (11/12)(15/17) - cos(alpha)(8/17)

sin(alpha - beta) = (11/12)(15/17) - sqrt(23/144)(8/17)

sin(alpha - beta) ≈ 0.210

Therefore, sin(alpha - beta) is approximately equal to 0.210.

Step-by-step explanation:

Find the 360° circumference of the circle ( pi * d)   then you want                   90 / 360ths of that

Radius  = 10 mi       then  d = 20 miles

Circumference = pi * 20  = 20 pi miles

    90 / 360   * 20 pi =  15.7 mi

Therefore , the solution of the given problem of angles comes out to be

Angle QMR = 30.

The place where the lines that make up a skew's ends meet determines the size of its largest and smallest walls. It is conceivable for two routes to cross at a junction. Angle is another outcome of two things interacting. They mirror dihedral shapes the most. A two-dimensional curve can be created by arranging two line beams in various configurations between their ends.

Here,

Angle QRM counts 90 degrees because it is a right angle (represented by the square in the diagram).

We can use the knowledge that the sum of all angles in a straight line is 180 degrees to determine angle QPR. A straight line is formed by angles QPB and BPR, so:

=> Angle QPB + Angle BPR =  180°.

Given that the triangular is equilateral, angle QPB is equal to 60 degrees.

=> BPR angle = 180 - 60 = 120 degrees.

We can now use the knowledge that a triangle's total angles equal 180 degrees to determine angle QMR. Triangle formed by angles QMR, QRM, and BMR results in:

Angles QMR, QRM, and BMR add up to 180 degrees.

=> Angle QMR+90+120=180

=> Angle QMR = 180 - 90- 120,

In mathematics, an equation is a statement that asserts the equality of two expressions. It consists of two sides, left-hand side (LHS) and right-hand side (RHS), separated by an equals sign (=). The expressions on either side of the equals sign can contain numbers, variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, and exponentiation. The goal of solving an equation is to find the value(s) of the variable(s) that make the equation true.

Here,

The amount of heat absorbed by a substance can be calculated using the formula:

Q = mcΔT

where Q is the amount of heat absorbed, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature. For water, the specific heat capacity is 4.184 J/g⋅K.

Using the given values, we can calculate the amount of heat absorbed as follows:

m = 70 g

c = 4.184 J/g⋅K

ΔT = (90 - 30)∘C = 60∘C
