The speeds have to be converted to km/min as well:
88 km/h = 88/60 km/min
76 km/h = 76/60 km/min
Let's define the location dimension x as x=0 at Town A, then x=976 in Town B.
With this we can set up two location equations:
Andy: x(t) = 88/60 t
Bernard: x(t) = 976 - 76/60 t
When they meet, the equations are equal, so we solve t for:
88/60 t = 976 - 76/60 t => t=510
Convert this number back to a clock time by adding 510 minutes to 9 AM, and you get 5:30 PM.

What is 26.99 round to the nearest tenth
Answers
What is 26.99 round to the nearest tenth?
To round to the nearest tenth, you need know whether the number next to tenth place is greater than 5 or lesser than 5. If its greater than 5, you need to round up. If its lesser than 5, you need to round down. Now, in the number 26.99 9 is in the tenth place. The number next to 9 is greater than 5, so just add on to the ones place, making the tenth and hundredth place 0. Zero has no value so whether you add the zero or not, it does not matter.
26.99 round to the nearest tenth ≈ 27.

The following data pairs represent the average temperature x (in degrees Fahrenheit) and electricity costs y (in dollars) for different homes: (65, 147), (59, 141), (71, 176), (78, 189), (82, 183), (85, 211), (88, 231), (91, 227), (84, 198), (79, 188), (63, 152), (59, 126) Which of the following values is most likely the closest to the correlation coefficient of the data?
Answers
The correlation coefficient of the given data pairs is most likely closest to 0.8694.
Explanation:The correlation coefficient measures the strength and direction of the relationship between two variables. To find the correlation coefficient, you can use the formula:
r = [n(Σxy) - (Σx)(Σy)] / sqrt{[n(Σx^2) - (Σx)^2][n(Σy^2) - (Σy)^2]}
Using this formula, you can calculate the correlation coefficient for the given data pairs. The closest value to the correlation coefficient will be 0.8694, option d.
The answer closest to the correlation coefficient of the data is 0.835.
To find the correlation coefficient of the given data pairs, we can use the formula:
r = (Σxy - (Σx)(Σy)/n) / sqrt((Σx^2 - (Σx)^2/n)(Σy^2 - (Σy)^2/n))
where Σ represents the sum, n is the number of data pairs, x is the average temperature, y is the electricity cost, and xy is the product of x and y.
To calculate the correlation coefficient, we first need to find the sums and products of the data pairs:
Σx = 65 + 59 + 71 + 78 + 82 + 85 + 88 + 91 + 84 + 79 + 63 + 59 = 924
Σy = 147 + 141 + 176 + 189 + 183 + 211 + 231 + 227 + 198 + 188 + 152 + 126 = 2259
Σxy = (65*147) + (59*141) + (71*176) + (78*189) + (82*183) + (85*211) + (88*231) + (91*227) + (84*198) + (79*188) + (63*152) + (59*126) = 219907
Using these values, we can calculate the correlation coefficient:
r = (219907 - (924*2259)/12) / sqrt((Σx^2 - (Σx)^2/12)(Σy^2 - (Σy)^2/12))
Calculating the remaining sums:
Σx^2 = (65^2) + (59^2) + (71^2) + (78^2) + (82^2) + (85^2) + (88^2) + (91^2) + (84^2) + (79^2) + (63^2) + (59^2) = 73482
Σy^2 = (147^2) + (141^2) + (176^2) + (189^2) + (183^2) + (211^2) + (231^2) + (227^2) + (198^2) + (188^2) + (152^2) + (126^2) = 827259
Plugging in the values:
r = (219907 - (924*2259)/12) / sqrt((73482 - (924^2)/12)(827259 - (2259^2)/12))
After performing the calculations, the correlation coefficient is approximately 0.835.
Therefore, the answer closest to the correlation coefficient of the data is 0.835.

Answers
B has to be the answer because the others are not.
Not C because a right triangle is not regular, i.e. and equilateral triangle.
Not D because a rectangle has different side lengths.
Answer:
Figure B appears to be a polygon under certain conditions.
Step-by-step explanation:
We are given the following information in the question:
Figure A is a hexagon with varying lengths.
Figure B is a pentagon.
Figure C is a right triangle.
Figure D is a rectangle.
We have to find which are the regular polygons.
A regular polygon is a polygon with all the sides equal and all the interior angles have equal measure.That is a regular polygon is equiangular and equilateral.Figure A is not regular because of varying length.
Figure B can be a regular pentagon provided it is equiangular and equilateral
Figure C cannot be a regular polygon because a right angle follows the Pythagoras theorem and all the three sides can never be equal in a right angled triangle.
Figure D cannot be a regular polygon as the length of only opposite sides are equal and not all sides are not equal.
Figure B appears to be a polygon under certain conditions.

A printer prints 28 photos in 8 minutes. a. How many minutes does it take to print 21 more photos? b. Construct a double number line diagram that represents the situation. How many minutes does it take to print 35 more photos?
Answers
[tex]\bf \begin{array}{ccll} photos&minutes\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 28&8\\ 49&m \end{array}\implies \cfrac{28}{49}=\cfrac{8}{m}\implies m=\cfrac{49\cdot 8}{28}[/tex]
what about 35 more? well, it already printed 49, and 35 more would then be 84,
[tex]\bf \begin{array}{ccll} photos&minutes\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 28&8\\ 84&m \end{array}\implies \cfrac{28}{84}=\cfrac{8}{m}\implies m=\cfrac{84\cdot 8}{28}[/tex]
It takes 6 minutes to print 21 more photos. It takes 10 minutes to print 35 more photos.
To determine the time it takes to print 21 more photos, we first need to calculate the rate at which the printer prints photos. We can do this by dividing the number of photos printed (28) by the time it takes to print them (8 minutes). This gives us a rate of 3.5 photos per minute.
Next, we can divide the number of additional photos (21) by the rate of photos per minute to find the time it takes to print them. This gives us 21 photos / 3.5 photos per minute = 6 minutes.
Therefore, it takes 6 minutes to print 21 more photos.
To construct a double number line diagram, we create two parallel number lines, one for the number of photos and one for the number of minutes. We mark the starting point on both lines as 0.
Next, we plot the point (28, 8) on the diagram, representing the fact that 28 photos are printed in 8 minutes.
To determine the time it takes to print 35 more photos, we can extend the number of photos line to the point (35 + 28, 8), which is (63, 8). This point represents the fact that 63 photos are printed in 8 minutes.
Finally, we can draw a vertical line from the point (63, 8) on the number of photos line to the number of minutes line. This line intersects the number of minutes line at the point (63, 8 + 10), which is (63, 18).
Therefore, it takes 10 minutes to print 35 more photos.
the point (1,1) is the image under the image under rhe translation (x,y) (x+3,y-3)
Answers
The pre-image of the point (1, 1) under the translation (x, y) -> (x+3, y-3) in a coordinate system is the point (-2, 4).
The student's question relates to a translation transformation in mathematics. A translation moves every point of a figure or a space by the same distance in a given direction. In this case, the student has provided a specific translation transformation, which is represented by the formula (x, y)
ightarrow (x+3, y-3). This transformation means that for any point with coordinates (x, y), the translated point will have coordinates where 3 is added to the x-coordinate and 3 is subtracted from the y-coordinate.
If the point (1,1) is an image under this translation, you can find its pre-image by reversing the translation. Thus, subtracting 3 from the x-coordinate of the image and adding 3 to the y-coordinate of the image gives the pre-image coordinates:
Pre-image x-coordinate: 1 - 3 = -2Pre-image y-coordinate: 1 + 3 = 4Therefore, the pre-image of the point (1, 1) under the given translation is (-2, 4).

What is 32.043 in expanded form
Answers
Final answer:
To express 32.043 in expanded form, break it into each digit's value based on its place: 30 (tens) + 2 (ones) + 0.04 (hundredths) + 0.003 (thousandths), resulting in 30 + 2 + 0.04 + 0.003.
Explanation:
The question asks about expressing the number 32.043 in expanded form. Expanded form is a way of writing numbers to show the value of each digit. It involves breaking down the number into each of its digits, multiplied by their respective place value. For the number 32.043:
The '3' is in the tens place, so it represents 30 or 3 * 10.The '2' is in the ones place, so it represents 2 or 2 * 1.The '0' is in the tenths place, so it represents 0 or 0 * 1/10. However, since it contributes no value, it's often omitted in expanded form.The '4' is in the hundredths place, so it represents 0.04 or 4 * 1/100.The '3' is in the thousandths place, so it represents 0.003 or 3 * 1/1000.Therefore, 32.043 in expanded form is 30 + 2 + 0.04 + 0.003.

if the area of a garden is 11 square feet what could be the dimensions of the garden
Answers
11 is a prime with factors 1 and 11.
Therefore, if the area of a (rectangular) garden is 11 square feet, then the possible dimension of the garden is 1 feet by 11 feet.
There can be multiple possible dimensions for a garden with an area of 11 square feet depending on its shape. For example, the garden could be 1ft by 11ft, 2ft by 5.5ft, or even a square with each side measuring 3.32 ft.
Explanation:The area of a garden is calculated by multiplying its length by its width. As the area of the garden is given as 11 square feet, possible dimensions for the garden could be 1 foot by 11 feet, 2 feet by 5.5 feet, or any other combinations that, when multiplied, give the result as 11 square feet.
Another way to look at it is that if you imagine the garden as a perfect square shape, each side would be approximately 3.32 feet since 3.32 multiplied by 3.32 equals roughly 11. This is because the square root of 11 is about 3.32.
