The number of minutes it would take Steve to weed the entire backyard by himself is 26.67 minutes.

Let's start by finding out how much of the backyard Hillary can weed in one minute by dividing the total time she takes by the amount of work she does in that time

Hillary's rate = 1 backyard / 80 minutes = 1/80 backyard per minute

Now, we know that Hillary worked alone for 32 minutes, so she weeded:

Hillary's work = Hillary's rate x Hillary's time = (1/80 backyard per minute) x (32 minutes) = 0.4 backyards

We also know that Hillary and Steve weeded together for 16 minutes, so they weeded

Combined work = Combined rate x Combined time

We can set up an equation to solve for the combined rate

Combined rate = Combined work / Combined time

Combined rate = (Hillary's work + Steve's work) / 16 minutes

We know that Hillary and Steve weeded the entire backyard together, so

Combined work = 1 backyard

Substituting the values we know into the equation for the combined rate, we get

1/16 = (0.4 + Steve's work) / 16

0.4 + Steve's work = 1

Steve's work = 0.6

So Steve can weed 0.6 of a backyard in 16 minutes.

Now, we can use Hillary's rate to find out how long it would take Steve to weed the entire backyard by himself

Steve's time = Steve's work / Steve's rate

Steve's time = 1 backyard / (0.6 backyard per 16 minutes)

Steve's time = 26.67 minutes

Step-by-step explanation:

To find the length of the ladder, we can use the Pythagorean theorem, which states that for any right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs¹.

In this case, the ladder forms a right triangle with the ground and the wall, where the ladder is the hypotenuse and the distance from the house and the height of the ladder are the legs. We can label these lengths as follows:

- c = length of ladder (hypotenuse)

- a = distance from house (leg)

- b = height of ladder (leg)

Using the Pythagorean theorem, we can write:

$$c^2 = a^2 + b^2$$

We are given that a = 33 feet and b = 44 feet, so we can plug in these values and solve for c:

$$c^2 = 33^2 + 44^2$$

$$c^2 = 1089 + 1936$$

$$c^2 = 3025$$

$$c = \sqrt{3025}$$

$$c \approx 55.0$$

Therefore, the length of the ladder should be about **55.0 feet**.

TRUE, f(x) have a greater x-intercept than g(x)

FALSE, f(x) have a greater slope than g(x)

The equation of the line in the table is written

To find the equation of the line passing through two points, we can use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

where

(x1, y1) are the coordinates of one point on the line,

m is the slope of the line, and

(x, y) are the coordinates of any other point on the line.

Let's use the points (-5, -22) and (1, 14) to find the equation of the line:

First, we need to find the slope of the line:

m = (y2 - y1) / (x2 - x1)

m = (14 - (-22)) / (1 - (-5))

m = 36 / 6

m = 6

Now we can use one of the points and the slope to write the equation of the line:

y - y1 = m(x - x1)

y - (-22) = 6(x - (-5))

y + 22 = 6(x + 5)

y + 22 = 6x + 30

y = 6x + 8

Therefore, the equation of the line passing through (-5, -22) and (1, 14) is y = 6x + 8.

comparing f(x) = 2x - 5 with g(x) = 6x + 8

f(x) have a greater y-intercept than g(x) FALSE since -5 < 8

f(x) have a greater x-intercept than g(x) TRUE since 5/2 > -8/6

It would be more interesting to look at median instead of mean or mode because it also provide information on central tendency of responses.

The response options 'underpaid', 'paid appropriately', and 'overpaid' are ordinal data.

Which means they have a natural order but no fixed numerical value.

As such it cannot meaningfully calculate a mean which requires numerical values for these responses.

The mode, which is the most common response may be of interest in some cases but it has limitations.

There may not be a clear mode since the responses are subjective and distributed across three categories.

Additionally, the mode does not capture the variability or spread of the responses.

The median however, is a useful measure of central tendency for ordinal data.

It represents the middle value when the responses are ranked in order of magnitude.

For example, if we have the following responses from 10 graduates,

underpaid, underpaid, paid appropriately, paid appropriately, paid appropriately, overpaid, overpaid, overpaid, overpaid, overpaid

The median would be 'paid appropriately' since it is the middle response when ranked in order of magnitude.

Looking at the median salary category would give us a sense of the typical response .

Step-by-step explanation:

Given speeds to school and back of 13.5 km/h and 10.5 km/h, respectively, and a total travel time of 36 minutes, you want to know the time to ride to school, and the distance.

The ratio of times is the inverse of the ratio of speeds over the same distance. The ratio of times is ...

  time to school : time to home = 10.5 : 13.5 = 7 : 9

Then the fraction of total time it takes to get to school is ...

  (7/(7+9))·(36 min) = 15.75 min = 0.2625 hour . . . . . . . 1 min = 1/60 hour

The distance can be found from the relation ...

  distance = speed · time

You would need approximately 381.51 cubic inches of air to fill up the basketball. The correct option is 381.51.

To calculate the volume of a sphere (which a basketball is approximately shaped like), you use the formula V = (4/3)πr³, where r is the radius (half the diameter) of the sphere.

So, the radius of the basketball would be 4.5 inches (half of 9 inches), and plugging that into the formula we get:

V = (4/3)π(4.5)³
V = (4/3)π(91.125)

The area swept clean by the wiper blade is 221.128 square inches.

To find the area swept clean by the wiper blade, we can calculate the area of the sector of a circle that the blade moves through.

The radius of the circle that the blade moves through is the length of the arm, which is 19 inches.

The angle that the blade moves through is 105 degrees.

To calculate the area of the sector, we need to convert the angle to radians:

105 degrees * (π/180) = 1.8326 radians (rounded to 4 decimal places)

The area of the sector is then:

(1/2) * r^2 * θ = (1/2) * (19^2) * 1.8326 = 325.628 square inches (rounded to 3 decimal places)

However, the area swept clean by the wiper blade is not the full area of the sector, as the blade itself has a width of 11 inches. Therefore, we need to subtract the area of the triangle formed by the blade and the two radii of the sector that intersect at the blade's pivot point.

The length of one of the radii is the length of the arm, which is 19 inches. The length of the other radius is 19 - 8 = 11 inches since the blade is mounted 8 inches from the pivot point.

Using the formula for the area of a triangle:

(1/2) * base * height = (1/2) * 11 * 19 = 104.5 square inches

Therefore, the area swept clean by the wiper blade is:

325.628 - 104.5 = 221.128 square inches (rounded to 3 decimal places)

So the area swept clean by the wiper blade is approximately 221.128 square inches.

Principle amount is $600 (P), rate of interest is 8\% per annum (R), and the number of years is 5 (N). Hence, here, the interest the man would be paying is $240 and the total money he'd be collecting at the end of 5-year tenure is $840.

For bought four pairs of earrings by annu and price of each being $25.00, then the average price of each pair of earrings is equals to the $20.00.

The average of a group of numbers is also known as mean of numbers. It is calculated by summing up all the numbers together and then dividing the resultant by the total number of numbers in the group. Annu bought four pairs of earrings. The price of one pair of earrings = $25.00

Also, she will get one pair free at buying four pairs of earrings. We have to determine the average price each pair of earrings. Number of pairs of earrings = 5

Total price paid by annu for earings = 4 × $25.00 = $ 100.00

That sum of prices of earings pairs = $100.00

Using the average formula, the average price = ( sum of each pair of earings prices )/total pairs of earrings she bought
