Answer:
5 minutes
Step-by-step explanation:
Volume of cylinder = πr²h
Radius, r = diameter / 2 = 1.8 /2 = 0.9
Volume of cylinder = 3.14 * 0.9² * 3.5
Volume = 8.9019 feet³
Drain rate = 1.7 ft per minute
Volume / drain rate
8.9019 / 1.7
= 5.2364117
= 5 minutes (nearest minute)

The area of a rectangle is 350 square meters. Find its width if its length is 50 meters
Step-by-step explanation:
For a given rectangle,the area(A) is the product of its length and width
A=lw, given A=350m² and l=50m
transposing the equation for w gives w=A/l
w=350m²/50m=7m
That's it
indicate the equation of the given line in standard form. the line that contains the point q(1,-2) and is parallel to rhe line whose equation is y-4=2/3(x-3)
Since the lines are parallel they have the same slope 2/3. use point slope form to get,
y+2=2/3(x-1)
y+2=2/3x-2/3
y=2/3x-8/3
3y=2x-8
2x-3y=8

Which images are tessellations?
Image 1 and 4
Image 3 and 2
Image 1 only
Image 3 and 4
Option - D - Image 3and 4 is correct
We have the following images.
We have to classify which image is a tessellations.
What are tessellations?tessellations is also called tiling which involves the covering up of rigid plane surface using the geometric shapes (tiles) ensuring that these shapes don't overlap and leave no gap.
In the image 3, we have a geometric shape called triangle which is used as a tile to cover the surface. These shapes don't overlap and leave no gap as they perfectly fit with one another. Similar is the case with image 4, where hexagonal tiles are used. Therefore, image 3 and 4 are tessellations. The images 1 and 2 does not have any predefined geometric shape and nothing can be said about their perfect fit. Hence these are not tessellations.
Hence, Option - D is correct.

Find the measure of each numbered angle or are.
Answer:
<1 = 138degrees
<2 = 156degrees
Step-by-step explanation:
From the diagram given;
angle at the vertex = 36degrees
Angle at the intercepted arc are <1 and 66degrees
Using the theorem;
Angle at the vertex is 1/2 the difference of the angles at the intercepted arcs
36 = 1/2(<1-66)
36*2 = <1-66
72 = <1 - 66
<1 = 72+66
<1 = 138degrees
Also since the sum of angle in a circle is 360degrees, hence;
<1 + <2 + 66 = 360
138 + <2 + 66 = 360
<2 + 204 = 360
<2 = 360 - 204
<2 = 156degrees

You open a case of Cherry Coke from the garage to put cans in the refrigerator. You put the
85°F cans in the 36°F refrigerator. After 5 minutes, the can temperature has gone down to
71°F. Find the constant "k" using Newton's Law of Cooling.
9514 1404 393
Answer:
k ≈ -0.06729
Step-by-step explanation:
The initial temperature difference is 85 -36 = 49 degrees. After 5 minutes, the temperature difference is 71 -36 = 35 degrees. The constant k is the natural log of the ratio of these temperature differences, divided by the time unit.
k = ln(35/49)/5 ≈ -0.06729
__
The equation for the temperature T of the can in the refrigerator is ...
T = 49e^(-0.06729t) +36
_____
Additional comment
Be careful with the sign. If you're filling in k in e^(-kt), then the sign of k will be positive. Above, we have taken the form of the exponential term to be e^(kt), so k is negative.

Jasmine made a new line plot for the lengths of another set of strings that the art teacher gave her for a new project. Two line plots are given. 1st line plot named as ALTDCString Lengths for Craft ProjectALTDC shows a number line from 6 to 14. The number line is divided into 4 equal parts. 1 cross on 6, 2 crosses on 8, 4 crosses on 12 and 1 cross on 14 is given. 2nd line plot named as ALTDCString Lengths for New ProjectALTDC shows a number line from 6 to 14. The number line is divided into 4 equal parts. 2 crosses on 8, 3 crosses on 10 and 3 crosses on 12 is given. Which of the following statements are true about the string lengths for the first craft project and the new project? Select all that apply. A. There are half as many 12-inch strings for the new project as for the craft project. B. There are twice as many 8-inch strings for the craft project as for the new project. C. Jasmine has the same number of strings for the new project as for the craft project. D. The total length of the strings for the craft project is greater than the total length for the new project. E. The length of the longest string is the same for both projects.
Answer:
C - Jasmine has the same number of strings for the new project as for the craft project
D - The total length of the strings for the craft project is greater than the total length for the new project.
The length of all the strings combined is 84 inches, while the length of the smallest string is 6 inches.
What is a line plot?A line plot is a graph that shows the frequency of each value by displaying data as points or checkmarks above a number line.
here, we have,
In the given line plot, if we consider each of the options with the plot given to us, we will get to know which of the options are true or not.
A.) A. The difference between the longest length and shortest length is 14 inches.
As given in the plot, the longest string is 14 units while the smallest is 6 units, therefore, the first option is incorrect.
B.) I have twice as many 12-inch strings as I do 8-inch strings.
In the plot since the number of dots represents the number of strings of a particular length, therefore, the number of strings of length 12-inches is 4 and the number of strings of length 8-inches is 2. Thus, the given options are correct.
C.) The total length of string that I have is 84 inches.
As per the plot, the number of strings of length 6 inches is 1, the number of strings of length 8 inches is 2, the strings of length 12inches is 4, and the number of strings of length 14 inches is 1. Thus, the sum of the length of all the strings is 84 inches.
Hence, the statement is correct.
D.) I cannot determine what the shortest string is by looking at my line plot.
As given in the plot, the length of the smallest string is 6 inches, thus, the statement is incorrect.
E.) Since I need 100 total inches of string for my project, I have enough string.
As the length of all the strings combined is just 84 inches, thus, the statement is incorrect.
Hence, the only option that is correct is 'B' and 'C'.

The mean area of homes in a certain city built in 2009 was 2438 square feet. Assume that a simple random sample of 11 homes in the same city built in 2010 had a mean area of 2,293 square feet, with a standard deviation of 225 square feet. An insurance company wants to know if the mean area of homes built in 2010 is less than that of homes built in 2009. Compute the P-value of the test. Write down your P-value. You will need it for the next question.
Answer:
The p-value of the test is 0.029.
Step-by-step explanation:
The mean area of homes in a certain city built in 2009 was 2438 square feet.
An insurance company wants to know if the mean area of homes built in 2010 is less than that of homes built in 2009.
This means that at the null hypothesis we test if the mean is the same as in 2009, that is:
[tex]H_0: \mu = 2438[/tex]
At the alternate hypothesis, we test that if it is less, than is;
[tex]H_a: \mu < 2438[/tex]
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.
2438 is tested at the null hypothesis:
This means that [tex]\mu = 2438[/tex]
Assume that a simple random sample of 11 homes in the same city built in 2010 had a mean area of 2,293 square feet, with a standard deviation of 225 square feet.
This means that [tex]n = 11, X = 2293, s = 225[/tex]
Value of the test statistic:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{2293 - 2438}{\frac{225}{\sqrt{11}}}[/tex]
[tex]t = -2.14[/tex]
Compute the P-value of the test.
Probability of finding a mean less than a value(in this case, 2293) is a one-tailed test.
The pvalue is found for a one-tailed test, with t = -2.14 and 11 - 1 = 10 degrees of freedom. With the help of a calculator, the pvalue of the test is of 0.029
The p-value of the test is 0.029.

∠A +∠B +∠C = 180°
∠A + 57° + 57° = 180° . . . fill in the known numbers
