A shipping container is in the shape of a right rectangular prism with a length of 2 feet, a width of 3 feet, and a height of 5 feet. The container is completely filled with contents that weigh, on average, 0.84 pound per cubic foot. What is the weight of the contents in the container, to the nearest pound?
Answer:
13 pounds
Step-by-step explanation:
volume = base area × height
area of a rectangular triangle = a×b/2
Vp = (2×3/2) × 5 = 3×5 = 15 ft³
weight of contents = 15 × 0.84 = 12.6 pounds = 13 pounds rounded.
Point J is on line segment \overline{IK} IK . Given IK=5x,IK=5x, IJ=4,IJ=4, and JK=4x,JK=4x, determine the numerical length of \overline{IK}. IK
Answer:
IK = 20
Step-by-step explanation:
If Point J is on the line segment IK, then;
IK = IJ + JK
Given that
IJ = 4
IK = 5x
JK = 4x
Substitute into the expression
5x = 4 + 4x
5x - 4x = 4
x = 4
Get the value of IK
IK = 5x
IK = 5(4)
IK = 20
Hence the numerical length of IK is 20

The dot plot showed the number of flowers on a rosebush: 18, 18, 18, 18, 20, 20, 22, 23 The number 19 is used to summarize the data. What does this number measure?
Answer:
19 measures the median
Step-by-step explanation:
The dot plot is not shown, but the question can still be answered.
We have:
[tex]Samples: 18, 18, 18, 18, 20, 20, 22, 23[/tex]
[tex]n = 8[/tex]
Calculate the median position using:
[tex]Median = \frac{n + 1}{2}th[/tex]
[tex]Median = \frac{8 + 1}{2}th[/tex]
[tex]Median = \frac{9}{2}th[/tex]
[tex]Median = 4.5th[/tex]
4.5th means the median is the mean of the 4th and 5th item.
We have:
[tex]4th = 18[/tex]
[tex]5th = 20[/tex]
So:
[tex]Median = \frac{18 + 20}{2}[/tex]
[tex]Median = \frac{38}{2}[/tex]
[tex]Median = 19[/tex]

[tex]r=\frac{7±3\sqrt{5} }{2}[/tex]
Ignore the A before the ±. It wouldn't let me type it correctly.
Step-by-step explanation:
2r² + 7r - 1 = 3r²
2r² + 7r - 1 - 3r² = 0
- r² + 7r - 1 = 0
- (r² - 7r + 1) = 0
- (r² - 7r + 1) ÷ - 1 = 0 ÷ - 1
r² - 7r + 1 = 0
[tex]r=\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex]
Ignore the A before the ±. It wouldn't let me type it correctly.
r² - 7r + 1 = 0
a = 1
b = - 7
c = 1
[tex]r=\frac{-(-7)±\sqrt{(-7)^{2}-4((1)(1)) } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{49-4((1)(1)) } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{49-4 } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{45 } }{2(1)}[/tex]
[tex]r=\frac{-(-7)±\sqrt{(3)(3)(5) } }{2(1)}[/tex]
[tex]r=\frac{7±(\sqrt{3 } )(\sqrt{3})(\sqrt{5}) }{2(1)}[/tex]
[tex]r=\frac{7±3\sqrt{5} }{2}[/tex]
Two separate equations
[tex]r=\frac{7+3\sqrt{5} }{2}[/tex]
[tex]r=\frac{7-3\sqrt{5} }{2}[/tex]

rhombus wxyz with vertices w(1 0) x(4,-1) y(5,-4) and z(2,-3)
Answer:
W 2,3
X 5,3
Y 1,2
Z 8,4
Step-by-step explanation:
The coordinates of the Rhombus after the dilation is W' ( 3 , 0 ) , X' ( 12 , -3 ) , Y' ( 15 , -12 ) and Z' ( 6 , -9 )
What is Dilation?Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent
The result of dilation is that the shapes and boundaries of objects in the input image are expanded or thickened. It is often used in conjunction with other morphological operations such as erosion, opening, and closing to manipulate and enhance images.
Given data ,
Let the coordinates of the rhombus be represented as WXYZ
where W' ( 1 , 0 ) , X ( 4 , -1 ) , Y ( 5 , -4 ) and Z ( 2 , -3 )
Now , the dilation scale factor is k = 3 centered at origin
So , result of this transformation is an image with the same shape as the original
The coordinates of the dilated figure is W'X'Y'Z'
where W' ( 3 , 0 ) , X' ( 12 , -3 ) , Y' ( 15 , -12 ) and Z' ( 6 , -9 )
Hence , the dilation is solved

6n + 12 = -60 - 35
Answer:
6n + 12 = -60 - 35
-12 -12
6n = -107
Divide by 6 on both sides:
N = -17.8333333333 around -17
Step-by-step explanation:
We need to isolate the variable meaning keeping the variable by itself on the left side. In order to do that we must get rid of any constants or co-efficients.
Answer:
Hey mate......
Step-by-step explanation:
This is ur answer.....
6n + 12 = -60 -35= 6n + 12 = -95
= 6n = -95 - 12
= 6n = -107
= n = -107 / 6

A box contains 4 marbles: 1 blue, 1 yellow, 1 green, and 1 white. A marble is randomly drawn from the box and a number cube, labeled 1 through 6, is tossed. What is the probability of getting a yellow marble and an odd number? Express as a fraction in simplest form.
Answer:
The answer is 1/8
Step-by-step explanation:
There are 4 marbles in the box and one of them is a yellow marble. The odds of getting a yellow marble fr the box is 1/4.
A number cube labeled 1 through 6 has 6 numbers, which are 1, 2, 3, 4, 5 and 6. The odd numbers in the cube are 1, 3 and 5. The probability of getting an odd number from the cube is 3/6, which is simplified to 1/2.
To find the probability of both cases occurring, both fractions should be multiplied.
1/4 * 1/2 = 1/8

It takes four hours to mow two
lawns. How many lawns can he mow
in 10 hours?
five lawns?
ten lawns?
six lawns?
Answer:
5
Step-by-step explanation:
The amount of lawns that he can mow in 10 hours is; A: five Lawns
What is the amount of work to be done?
We are told that it takes a time of 4 hours to mow 2 lawns. Thus, amount of lawn he can mow in 1 hour = 2/4 = 0.5 lawn per hour
Thus, amount of lawn he can mow in 10 hours = 0.5 * 10 = 5 lawns
In conclusion he will mow 5 lawns in 10 hours.

Answer:
AEB =43
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
AED + AEB = 180
137+AEB = 180
AEB = 180-137
AEB =43
Answer:
[tex]\text{B. }43^{\circ}[/tex]
Step-by-step explanation:
Angles [tex]\angle AED[/tex] and [tex]\angle AEB[/tex] are supplementary, meaning they add up to 180 degrees, because they form one side of a line.
Thus, we have:
[tex]\angle AED+\angle AEB=180,\\137+\angle AEB=180,\\\angle AEB=\boxed{43^{\circ}}[/tex]

Step-by-step explanation:
A research center project involved a survey of 846 internet users. It provided a variety of statistics on internet users. (a) The sample survey showed that 94% of respondents said the internet has been a good thing for them personally. Develop a 95% confidence interval for the proportion of respondents who say the internet has been a good thing for them personally. (Round your answers to four decimal places.) 0.9239 Incorrect: Your answer is incorrect. to 0.9561 Incorrect: Your answer is incorrect. (b) The sample survey showed that 67% of internet users said the internet has generally strengthened their relationship with family and friends. Develop a 95% confidence interval for the proportion of respondents who say the internet has strengthened their relationship with family and friends. (Round your answers to four decimal places.) 0.6385 Incorrect: Your answer is incorrect. to 0.7015 Incorrect: Your answer is incorrect.
Answer:
(a) (0.9240, 0.956)
(b) (0.6383, 0.7017)
Step-by-step explanation:
The number of internet users involved in the survey, n = 846
The percentage of the respondents that said the internet has been good thing for them personally, [tex]\hat p[/tex] = 94%
(a) The confidence interval of a percentage is given as follows;
[tex]CI=\hat{p}\pm z\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex]
The z-value for 95% confidence interval = 1.96
We get;
[tex]CI=0.94\pm 1.96\times \sqrt{\dfrac{0.94 \times (1-0.94)}{846}} \approx 0.94 \pm 1.6003 \times 10^{-2}[/tex]
CI = 0.9240 ≤ [tex]\hat p[/tex] ≤ 0.956 = (0.9240, 0.956)
(b) The percentage of the internet users that said the internet has directly strengthened their relationship with their families, [tex]\hat p[/tex] = 67% = 0.67
The 95% confidence interval is therefore;
[tex]CI=0.67\pm 1.96\times \sqrt{\dfrac{0.67 \times (1-0.67)}{846}} \approx 0.67 \pm 3.1686\times 10^{-2}[/tex]
From which we have;
CI = 0.6383 ≤ [tex]\hat p[/tex] ≤ 0.7017 = (0.6383, 0.7017)
(look at the pictures)
Step-by-step explanation:
the function A, according to the tables
=> the equation : f(x) = 2x +3
the slope = 2
the function B, according to the graph
=> the equation : f(x) = 3x -2
the slope = 3
based on the value of the slope, the function B has a greater rate of change
Answer:
Step-by-step explanation:
Find the slope for the two functions
Function A:
(1 , 5) & (2 , 7)
Slope = Change in y ÷ change in x
[tex]= \frac{7-5}{2-1}\\\\= \frac{2}{1}\\\\= 2[/tex]
Function B:
(1 ,1) , (2 , 4)
Slope = [tex]= \frac{4-1}{2-1} = \frac{3}{1}[/tex]
= 3
Function B has a greater rate of change
