If the volume of the planter is 2,560 cubic inches,how tall is the planter
Answer:
Height of Planter = H = 20 in²
Step-by-step explanation:
As the planter is not given in the question, the question is incomplete.
First, lets complete the question by attaching the diagram related to this question.
(SEE THE ATTACHMENT)
Lets consider the right angled triangle that is formed at the top of the planter, as shown in the diagram attached.
The right angled triangle has a width of 16 inches and a heights of 16 inches as well.
We know that the Area of a triangle can be calculated by following formula:
[tex]A=\frac{1}{2}\cdot(width)\cdot(height)[/tex]
Substitute the values to find Area:
[tex]Area = \frac{1}{2}\cdot16\cdot16\\Area = 128 in^2[/tex]
We also know that the Volume of a triangular prism is given by:
[tex]Volume=(Area)\cdot(Height)[/tex]
Where
Area = Area of the face = 128 in²
Height = Height of the planter = H
Volume = 2560 in³
Substitute the values and solve for H:
[tex]2560=128\cdot{H}\\H=\frac{2560}{128}\\H=20in^2[/tex]

X< 62°
(4x - 2)°
Y
Value: 10
x is equal to
degrees.
Angle Y measures
degrees.
Answer:
x is equal to 16 degrees
Angle measures 62 degrees
Step-by-step explanation:
From Law of Sines:
XW/sin(∠Y) = WY/sin(∠X)
From the picture
XW = 8
WY = 8
∠X = 62°
Replacing into the equation:
8/sin(∠Y) = 8/sin(62°)
∠Y = 62°
Angle Y is also equal to:
∠Y = 4x - 2
62 = 4x - 2
62 + 2 = 4x
64/4 = x
16° = x

Step-by-step explanation:
Use a net to find the surface area of the open cylinder with only one base. Use 3.14 for pi.
Answer:
251.20 cm square
Step-by-step explanation:
As given in figure
height of cylinder = 2 cm
radius of cylinder = 8 cm
lateral surface area of cylinder is given by = [tex]\pi r l[/tex]
where r is the radius and l is the height
Therefore, lateral surface area of given cylinder
[tex]\pi r l = 3.14*8*2 = 50.24[/tex]
area of base is give by [tex]\pi r^2[/tex]
since there is only one base area of that base
= [tex]\pi r^2 = 3.14*8^2 = 3.14*64 = 200.96[/tex]
Thus,
Total surface area of open cylinder = 50.24 + 200.96 = 251.20 cm square
Part A
Choose the inequality and solution to represent the number of cans, c, that Xander must still collect.
A. c + 64 ≤ 120; c ≤ 56
B. c + 120 ≤ 64; c ≤ –56
C. c + 64 ≥ 120; c ≥ 56
D. c + 120 ≥ 64; c ≥ –56
Part B
Choose the graph of the solution on the number line.
Answer:
Part A: A
Part B: A
Step-by-step explanation:
1)
the inequality should be less than or equal to, since we need to find how many are left
now, the answer B is wrong, since there can't be negative 56, since Xander collected some cans, though he still must collect a few
thus, the answer is A
2)
A again is correct, since it represents:c ≤ 56
B represents c ≥ 56
C represents c ≤ –56
D represents c ≥ -56
Matrix C is a transformation of matrix B, and matrix is a transformation of matrix A as shown below.

Step-by-step explanation:
A line is parallel to y = 4x – 2 and
intersects the point (5, -11).
What is the equation of this parallel line?
y = [?]x +
Hint: Use the Point-Slope Form: y - y1 = m(x - X1)
Then write the equation in slope-intercept form.
Answer:
y=4x-31
Step-by-step explanation:
Ignore the hint. Point slope form makes everything so much harder than it has to be.
Parallel lines always have the same slope, in this case 4.
So our equation is now: y = 4x + b
Let's solve for b by plugging in (5, -11), as it's the only point we know is on the parallel line.
-11 = 4(5) + b
-11-20 = b
b = -31
So plug in b: y = 4x - 31

Answer:
y = -4x + 15.
Step-by-step explanation:
To find the equation of a line perpendicular to y = -2 and passing through the point (4, -1), we can use the point-slope form of a linear equation.
The given line y = -2 has a constant slope of 0 since there is no variable term involving x. A line perpendicular to it will have an undefined slope.
Using the point-slope form, we have:
y - y₁ = m(x - x₁),
where (x₁, y₁) represents the coordinates of the given point (4, -1), and m represents the slope.
Since the slope is undefined, the equation becomes:
y - (-1) = undefined(x - 4).
Simplifying:
y + 1 = undefined(x - 4).
Now, we can write the equation in slope-intercept form by substituting the slope as -4 (the negative reciprocal of 0):
y + 1 = -4(x - 4).
Expanding the right side:
y + 1 = -4x + 16.
To isolate y, we can subtract 1 from both sides:
y = -4x + 16 - 1.
Combining the constants:
y = -4x + 15.
Therefore, the equation of the perpendicular line is:
y = -4x + 15.
Which graph represents the function f(x) = 4|x|? (please answer honestly I'm on a timed test rn)
Answer:
The graph that corresponds to the function is B.
Step-by-step explanation:
We want to see which one of the given graphs represents the function f(x) = 4*|x|
The correct option is the second graph.
How to find the correct graph?
Here we want to find the graph of the absolute value function:
f(x) = 4*|x|
To get it, we can evaluate the function in some values of x and then see which graph contains these points.
for example for x = 1 and x = -1 we have:
f(1) = 4*|1| = 4
f(-1) = 4*|-1| = 4
Then we need to see which graph contains the points (1, 4) and (-1, 4)
We can see that the only graph that contains these points is the second one, so the correct option is the second graph.

Bill needs to edge his yard with the dimensions in the shape below. What distance will he have walked after completing his edging? Round your answer to one decimal place. Do not include units in your answer.
Answer:
37.8
Step-by-step explanation:
The distance is the addition of all sides of the figure. Then, we need to find the length of the diagonal (d). To do that we have to make a right triangle with height (h) = 5 m. Given that the top length is 12 m and the bottom length is 15 m, the base (b) of the triangle is 15 - 12 = 3 m
Using Pythagorean theorem:
d² = h² + b²
d² = 5² + 3²
d = √34
d = 5.8 m
Therefore, the distance he will have walked is 5.8 + 12 + 15 + 5 = 37.8 meters

To create an image, Figure C is going to be translated 2 units to the left, reflected across the y-axis, and rotated 270° clockwise about the origin. What must be true about Figure C and its image?
Answer:
BRO THE IMAGE FORMED IS CONGRUENT
Step-by-step explanation:
Answer:
They are congruent
Step-by-step explanation:
Figure C will still stay the same shape and size because there was no dilation involved in the process. The image of Figure C will be in quadrant 1 and rotated 270° clockwise. Congruent means it is the same shape and size. So our answer is "They are congruent".

The mean annual salary paid to all employees in a company was 1500 Kenya pounds The mean annual salaries paid to male and female employees were 1560 Kenya pounds and 1260 Kenya pounds respectively. Determine the percentages of males and females employed by the company.
Answer:
[tex]Male = 80[/tex]%
[tex]Female = 20%[/tex]%
Step-by-step explanation:
Given
Annual Mean Salary = 1500
Annual Mean Salary (Male) = 1560
Annual Mean Salary (Female) = 1260
Required
Percentage of male and female employed
Represent male by m and female by 4
So, total employees = m + f
The mean of an observation is calculated as thus;
Mean = Summation of observation divided by number of observations
For Male:
Annual Mean = Total Salary/Number of males
Recall that Annual Mean = 1560
Number of males = m;
The formula becomes
[tex]1560 = \frac{TotalSalary}{m}[/tex]
Multiply both sides by m
[tex]1560 * m = \frac{TotalSalary}{m} * m[/tex]
[tex]1560m = TotalSalary[/tex]
For Female:
Annual Mean = Total Salary/Number of females
Recall that Annual Mean = 1260
Number of females = f;
The formula becomes
[tex]1260 = \frac{TotalSalary}{f}[/tex]
Multiply both sides by f
[tex]1260 * f = \frac{TotalSalary}{f} * f[/tex]
[tex]1260f = TotalSalary[/tex]
Total Annual Salary = Annual Salary of Male + Annual Salary of Female
Total Annual Salary = 1560m + 1260f
The mean annual salary is calculated as thus;
Mean Annual Salary = Total Annual Salary/Total Employees
Recall that Total Employees = m + f and Mean Annual Salary = 1500
So, the formula becomes
[tex]1500 = \frac{1560m + 1260f}{m+f}[/tex]
Multiply both sides by m + f
[tex]1500(m+f) = \frac{1560m + 1260f}{m+f} * (m+f)[/tex]
[tex]1500(m+f) = 1560m + 1260f[/tex]
Open brackets
[tex]1500m+1500f- = 1560m + 1260f[/tex]
Collect like terms
[tex]1500f -1260f = 1560m - 1500m[/tex]
[tex]240f = 60m[/tex]
Divide through by 60
[tex]\frac{240f}{60} = \frac{60m}{60}[/tex]
[tex]4f = m[/tex]
Reorder
[tex]m = 4f[/tex]
At this point, the percentage male and female can be calculated;
Male = (Number of male/Total Employees) * 100%
[tex]Male = \frac{m}{m+f} * 100[/tex]%
Substitute 4f for m
[tex]Male = \frac{4f}{4f+f} * 100[/tex]%
[tex]Male = \frac{4f}{5f} * 100[/tex]%
[tex]Male = \frac{4}{5} * 100[/tex]%
[tex]Male = 0.8 * 100[/tex]%
[tex]Male = 80[/tex]%
If percentage of male = 80%
Percentage of Female = 100% - 80%
[tex]Female = 20%[/tex]%
