The temperature at 11:00 A.M. yesterday was 78°F.

To find the temperature at 11:00 A.M., we need to subtract 9 from the temperature at 4:00 P.M. because the temperature rose 9 degrees between those times. So, we can use the following equation:

Temperature at 11:00 A.M. = Temperature at 4:00 P.M. - 9

We know that the temperature at 4:00 P.M. was 87°F, so we can substitute that into the equation and solve for the temperature at 11:00 A.M.:

Temperature at 11:00 A.M. = 87 - 9

Temperature at 11:00 A.M. = 78°F

Therefore, the temperature at 11:00 A.M. yesterday was 78°F.

It's important to remember that when solving word problems like this, we need to pay close attention to the details and make sure we understand what the question is asking us to find. In this case, we needed to use the information given about the temperature rising 9 degrees between 11:00 A.M. and 4:00 P.M. to find the temperature at 11:00 A.M. By using the equation provided and substituting in the known values, we were able to solve for the unknown temperature at 11:00 A.M.

Answer:

y = (-2/5)x+b

Step-by-step explanation:

First plug these into the y=mx+b equation:

-5 = (-2/5)(10)+b.

Then solve for b:

-5 = -4+b

Add 4 to both sides:

-1 =b.

Therefore, the equation of the line is y = (-2/5)x+b. You can also double check this by plugging 10 into the equation we just obtained.

The cost of a croissant before the increase was $0.75, the cost of a cup of coffee was $0.75, and the cost of a fruit bowl was $2.25.

Let's start by assigning variables to the cost of each item before the price increase. Let x be the cost of a croissant, y be the cost of a cup of coffee, and z be the cost of a fruit bowl.

From the problem statement, we know that:

x + y + z = 5.25 (total cost before price increase)

z = 3x (fruit bowl costs 3 times as much as a croissant)

Substituting z = 3x into the first equation, we get:

x + y + 3x = 5.25

4x + y = 5.25

Now we need to solve for x and y. We don't have an equation directly relating the price increase to the new prices, but we can use the percentage increase to write:

New croissant price = x + 0.15x = 1.15x

New coffee price = y + 0.4y = 1.4y

The new total cost will be:

1.15x + 1.4y + z

Substituting z = 3x, we get:

1.15x + 1.4y + 3x

Simplifying this expression and using the equation 4x + y = 5.25 to eliminate y, we get:

1.15x + 1.4y + 3x = 4.15x + 1.4(5.25 - 4x)

4.15x + 1.4(4x - 5.25) = 4.55x - 5.85

Therefore, the new total cost will be $4.55x - $5.85. To find the cost of each item before the increase, we can solve the system of equations:

4x + y = 5.25

z = 3x

Substituting z = 3x into the first equation, we get:

4x + y + 3x = 5.25

7x + y = 5.25

Solving for y in terms of x, we get:

y = 5.25 - 7x

Substituting this expression into the equation for the new total cost, we get:

4.55x - 5.85 = 1.15x + 1.4(5.25 - 4x) + 3x

Simplifying and solving for x, we get:

x = 0.75

Substituting this value of x into the equation for y, we get:

y = 5.25 - 7(0.75) = 0.75

Substituting x and z = 3x into the equation for the total cost before the increase, we get:

0.75 + 0.75 + 3(0.75) = 3.75

Therefore, the cost of a croissant before the increase was $0.75, the cost of a cup of coffee was $0.75, and the cost of a fruit bowl was $2.25.

The annual rate as a percent is approximately 4.86% per year.

To find the annual rate as a percent, we first need to understand the function that Robert is using. The function [tex]f(x) = 1000(1.0375)^x[/tex] represents the amount of money Robert earns each year based on his initial investment of $1000 and the interest rate of 3.75% (as represented by the value 1.0375, which is 1 + 0.0375).

To calculate the annual rate as a percent, we need to isolate the interest rate from the function. We can do this by using logarithms. Taking the logarithm of both sides of the equation, we get:

log(f(x)) = log(1000) + x*log(1.0375)

Now, we can solve for the interest rate (represented by the value of 1.0375) by dividing both sides of the equation by x and then taking the antilog of the result:

1.0375 = antilog[(log(f(x)) - log(1000))/x]

Using this formula, we can plug in any value for x (representing the number of years Robert has held his investment) and find the corresponding interest rate. For example, if Robert has held his investment for 5 years, we can calculate the interest rate as:

1.0375 = antilog[(log(f(5)) - log(1000))/5]

This gives us an interest rate of approximately 4.86% per year. So, to answer the original question, the annual rate as a percent is approximately 4.86%.

Drawing a number line is a useful way to visualize the relationship between tons and pounds and can help make conversions easier to understand.

If we were to draw a number line that shows the relationship between tons and pounds, we would start with the fact that one ton is equivalent to 2000 pounds. We would then draw tick marks on the number line for every whole number from 0 to 10, with each tick mark representing 100 pounds. So, the tick mark at 0 would represent 0 pounds, the tick mark at 1 would represent 100 pounds, the tick mark at 2 would represent 200 pounds, and so on. The tick mark at 20 would represent 2000 pounds, or one ton.

We could then continue the number line past 20 to show larger quantities of tons and pounds, with each additional tick mark representing another ton (2000 pounds). For example, the tick mark at 30 would represent 3000 pounds, or 1.5 tons, the tick mark at 40 would represent 4000 pounds, or 2 tons, and so on.

A bowling ball moving at 11 meters per second will have approximately 537.64 joules of energy, rounded to the nearest hundredth.

The kinetic energy (E) of a moving object varies directly with the square of its velocity (v). To write the equation relating E to v, we can use the formula: E = k * v^2, where k is a constant of proportionality. Given a bowling ball traveling at 15 meters per second with 1000 joules of energy, we can find the value of k:

1000 = k * (15^2)
1000 = k * 225
k ≈ 4.44

So, the equation relating the kinetic energy and velocity is: E ≈ 4.44 * v^2.

Now, we want to find the energy of the bowling ball when it's moving at 11 meters per second. Using the derived equation:

E ≈ 4.44 * (11^2)
E ≈ 4.44 * 121

[tex]\overset{\frown}{BX}=\angle BCX=2\angle BNX[/tex]

Step-by-step explanation:

A chord is a straight line joining two points on the circle.

Therefore, the chords in the given diagram are BN and XN.

An inscribed angle is the angle formed (vertex) when two chords meet at one point on a circle.

Therefore, the inscribed angle in the given diagram is BNX.

An intercepted arc is the arc that is between the endpoints of the chords that form the inscribed angle.

Therefore, the intercepted arc in the given diagram is BX.

The radius is a straight line joining the center to a point on the circle.

Therefore, the radii in the given diagram are CB and CX.

The central angle of a circle is the angle formed at its center by two radii.

Therefore, the central angle in the given diagram is BCX.

[tex]\hrulefill[/tex]

The measure of the central angle of a circle is equal to the measure of the corresponding intercepted arc. Therefore:

    [tex]\angle BCX=\overset{\frown}{BX}[/tex]

According to the Inscribed Angle Theorem, the measure of an inscribed angle is half the measure of the intercepted arc. Therefore:

    [tex]\angle BNX=\dfrac{1}{2}\overset{\frown}{BX}[/tex]

So the relationship between the arc BX, the central angle BCX and the inscribed angle BNX is that both the arc and central angle are equal to twice the inscribed angle:

The volume of one smaller box is 1 cubic foot.

The volume of one smaller box is calculated by raising the length of its sides to the power of 3, so the volume of one smaller box is:

Volume (smaller box) = (1 foot)³ = 1 cubic foot

The number of smaller boxes that fit into a shipping container is obtained by multiplying the number of boxes that fit along each dimension, so the number of smaller boxes that fit into a shipping container is:

Number of smaller boxes = 20 boxes (width) × 40 boxes (length) × 20 boxes (height) = 16,000 boxes

To calculate the volume of the large shipping container, we need to multiply the length, width, and height of the container. Since each dimension is given in terms of the number of boxes it can hold, we need to multiply each dimension by the length of one smaller box (1 foot) to obtain the dimensions in feet. Therefore, the volume of the large shipping container is:

Volume of the large shipping container = 20 boxes (width) × 1 foot (length of one smaller box) × 40 boxes (length) × 1 foot (length of one smaller box) × 20 boxes (height) × 1 foot (length of one smaller box) = 16,000 cubic feet

A 16-inch radius tire would require 75 revolutions to travel the same distance as a 12-inch radius tire that made 100 revolutions.

Let's start by defining some variables. Let "r" represent the radius of the tire and "n" represent the number of revolutions it makes over a fixed distance. We are given that the number of revolutions is inversely proportional to the radius of the tire. This means that as the radius increases, the number of revolutions decreases, and vice versa. We can express this relationship mathematically as follows:

n = k/r

Here, "k" is the constant of variation, which remains the same for any given tire traveling over the same distance. To solve the problem, we need to find the value of "k" first. We know that a 12-inch radius tire makes 100 revolutions to travel a certain distance. Substituting these values into the equation, we get:

100 = k/12

Solving for "k," we get k = 1200. Now we can use this value to find the number of revolutions required by a 16-inch radius tire to travel the same distance:

n = 1200/16 = 75

Therefore, a 16-inch radius tire would require 75 revolutions to travel the same distance as a 12-inch radius tire that made 100 revolutions.

In summary, we defined the variables, identified the constant of variation, wrote the equation (n=k/r), found the value of the constant by using the given information, and used it to solve the problem by finding the number of revolutions required by a tire with a different radius.

The expression that represents Evelyn's grocery bill after the coupon is applied is 0.92c. Therefore, the correct option is D.

If Evelyn has a coupon that will reduce her grocery bill by 8% and c represents the cost of her groceries, the expression that represents Evelyn's grocery bill after using the coupon is 0.92c. It is determined as follows.

1. The coupon reduces the bill by 8%, which means Evelyn will pay 100% - 8% = 92% of the original cost.

2. Convert the percentage to a decimal: 92% = 0.92

3. Multiply the original cost (c) by the decimal: 0.92c

So, the correct answer is option D: 0.92c.

The null and alternative hypotheses are H₀: μ₁ - μ₂ = 0 and H₁: μ₁- μ₂ ≠ 0 and the test statistic value is equal to 0.45.

The null hypothesis (H₀) states,

That there is no significant difference between the population means of the experimental group and the control group.

The alternative hypothesis (H₁) states that there is a significant difference between the two means.

State the hypotheses as,

H₀: μ₁ - μ₂ = 0 (there is no difference in means)

H₁: μ₁- μ₂ ≠ 0 (there is a difference in means)

where μ₁ is the population mean of the experimental group

And μ₂ is the population mean of the control group.

The test statistic,

Use the t-test formula,

t = (x - μ) / (s / sqrt(n))

where x is the sample mean = 102

μ is the hypothesized population mean = 100

s is the sample standard deviation =88

n is the sample size= 10

Plugging in the values, we get,

t = (102 - 100) / (88 / sqrt(10))

 = 0.45

Therefore, the null and the alternative hypotheses states that H₀: μ₁ - μ₂ = 0 there is no difference in means and H₁: μ₁- μ₂ ≠ 0 there is a difference in means and the test statistic for a sample mean of 102 is 0.45.

809,304 people live in Charlotte, rounded to the nearest person.

To calculate the approximate population of Charlotte, you can use the given information:

Population density = 2,720 people per square mile
Area of Charlotte = 297.7 square miles

To find the total population, multiply the population density by the area:

Total population = Population density × Area
Total population = 2,720 people/sq mile × 297.7 sq miles

Total population ≈ 809,304 people

So, approximately 809,304 people live in Charlotte, rounded to the nearest person.
