Jordan built her cat Tuna a new scratching post. She needs to cover the post with carpet.
How much carpet does Jordan need to cover the surface of the post, including the bottom?
Answer:
3800 square centimeters
Step-by-step explanation:
We need to find the surface of the rectangular prism shown.
The surface area is the area of all the surfaces (including the bottom and top).
There are 6 surfaces, top and bottom is squares and 4 sides are rectangles.
The area of square is side * side, and
The area of rectangle is length * width
Top Area = 10 * 10 = 100
Bottom Area = 10 * 10 = 100
Area of 1 side = 90 * 10 = 900
Hence, area of 4 of these same sides is: 900 * 4 = 3600
Total Surface Area = 3600 + 100 + 100 = 3800
Total Carpet Needed = 3800 square centimeters
Answer:
3800
Step-by-step explanation:
If (3, 10) is the endpoint of a line segment, and
(-2, 3) is its midpoint, find the other endpoint.
Answer:
The required points of the given line segment are ( - 7, - 4 ).
Step-by-step explanation:
Given that the line segment AB whose midpoint M is ( - 2, 3 ) and point A is ( 3, 10), then we have to find point B of the line segment AB -
As we know that-
If a line segment AB is with endpoints ( [tex]x_{1}, y_{1}[/tex] ) and ( [tex]x_{2}, y_{2}[/tex] )then the mid points M are-
M = ( [tex]\frac{ x_{1} + x_{2} }{2}[/tex] , [tex]\frac{ y_{1} + y_{2} }{2}[/tex] )
Here,
Let A ( 3, 10 ), B ( x, y ) with midpoint M ( - 2, 3 ) -
then by the midpoint formula M are-
( - 2, 3 ) = ( [tex]\frac{ 3 + x}{2}[/tex] , [tex]\frac{ 10 + y}{2}[/tex] )
On comparing x coordinate and y coordinate -
We get,
( [tex]\frac{ 3 + x}{2}[/tex] = - 2 , [tex]\frac{ 10 + y}{2}[/tex] = 3)
( 3 + x = - 4, 10 + y = 6 )
( x = - 4 - 3, y = 6 - 10 )
( x = - 7, y = -4 )
Hence the required points A are ( - 7, - 4 ).
We can also verify by putting these points into Midpoint formula.
Final answer:
To find the other endpoint of a line segment with a known endpoint (3, 10) and midpoint (-2, 3), use the midpoint formula in reverse to calculate the coordinates, resulting in the other endpoint being (-7, -4).
Explanation:
To find the other endpoint of a line segment when given one endpoint and the midpoint, you can use the midpoint formula in reverse. The midpoint formula in two dimensions is
( (x1+x2)/2, (y1+y2)/2 ), where (x1, y1) and (x2, y2) are the endpoints of the line segment. Given that (3, 10) is one endpoint and (-2, 3) is the midpoint, we can set up equations to find the coordinates of the unknown endpoint (x2, y2).
To find x2, we use the formula for x-coordinate of the midpoint: (-2 + 3)/2 = (x2 + 3)/2. Solving for x2 gives us x2 = -2 - 3 = -7.
To find y2, we use the formula for y-coordinate of the midpoint: (3 + 10)/2 = (y2 + 10)/2. Solving for y2 gives us y2 = 2*3 - 10 = 6 - 10 = -4.
Therefore, the other endpoint of the line segment is (-7, -4).

Step-by-step explanation:
A boat travels upstream for 2 hours. the return trip only takes 1.7 miles because the boat travels 2.5 miles faster downstream. How far does the boat travel one way?
Answer:
the boat travel one way = 2 x 14.16 = 28.32 miles
Step-by-step explanation:
the return trip only takes 1.7 miles (?) ... is it 1.7 hours (?)
the boat travels 2.5 miles (per hour ?) faster downstream
I calculate it on the assumption of my guess stated above ...
X: represent the boat speed / hour
distance one way = 2X
and Distance also = 1.7 * (x + 2.5 ) on return
2x = 1.7 x + 1.7 * 2.5 = 1.7x + 4.25
0.3 x = 4.25
x = 14.16
the boat travel one way = 2 x 14.16 = 28.32 miles
If cos x= sin(20 + x)° and 0° < x < 90°, what is the value of x
If cos x= sin(20 + x)° and 0° < x < 90° then value of x is 35 degrees
Solution:
Given that:
[tex]cos x= sin (20 + x)[/tex]
We know that,
[tex]sin (a+b)=sin a \times cos b+cos a \times sin b[/tex]
[tex]cos x= sin (20 + x) = sin 20 cos x + cos 20 sin x[/tex]
[tex]cos x-sin20 \times cos x=cos 20 \times sin x[/tex]
Taking cos x as common,
[tex]cos x(1-sin 20)=cos 20 \times sin x[/tex]
[tex]\frac{(1-sin 20)}{(cos 20)}=\frac{sin x}{cos x }\\\\tan x = \frac{(1-sin 20)}{(cos 20)}[/tex]
By trignometric functions,
sin 20 = 0.34202
cos 20 = 0.939692
So,
[tex]tan x = \frac{1 - 0.34202}{0.939692}\\\\tan x = 0.7002[/tex]
Therefore,
x = arc tan (0.7002)
x = 35 degrees
Therefore value of x is 35 degrees
Method 2:cos x = sin (20 + x)
sin and cos are co - functions, which means that:
cos x = cos [90 - (20 + x)]
cos x = cos (90 - 20 - x)
cos x = cos (70 - x)
Therefore, x = 70 - x
x + x = 70
2x = 70
x = 35
Therefore value of x is 35 degrees

45 POINTS!! A JCpenny dress originally costs $69.00, but the final price is $20.70. What is the discount percentage? (Example: 50% off $20.00 is $10.00)
Answer:
70%
Step-by-step explanation:
69 - 20.70 = 48.3
48.3 / 69 = 0.7
0.7 x 100 = 70
The discount percentage for the JCPenney dress, discounted from an original price of $69.00 to a final price of $20.70, is calculated to be 70% off.
To calculate the discount percentage for the JCPenney dress, we need to find the difference between the original price and the final price, and then divide that by the original price. We can then multiply the result by 100 to get the percentage.
The original price of the dress is $69.00, and the final price is $20.70. The difference between these two prices is $69.00 - $20.70 = $48.30. This is the amount of the discount.
To find the discount percentage, we divide the discount amount by the original price: $48.30 / $69.00 = 0.7. To convert this decimal to a percentage, we multiply by 100: 0.7 imes 100 = 70%.
Thus, the dress is discounted by 70%.
Dev has 9 shells. Zoe has 55 shells, Zoe gives some shells to Dev. Now zoe has 3 times as many shells as dev. How many shells does Zoe give to Dev.
Answer:
number of shells zoe gives to dev = 7
number of shells zoe is left with = 55-7= 48
number of shells dev has = 9+7=16
Step-by-step explanation:
let the initial number of shells that dev has be A, and initial number of shells that zoe has be B.
let the number of shells that zoe gives to dev be x.
after giiving x shells zoe is left with 3 times the number of shell as that of dev.
therefore number of shells with zoe = 3×number of shells with dev.
number of shells with zoe = initial shells - x = 55-x
number of shells with dev = initial shells + number of shells he gets
= 9+x
therefore (55-x)=3×(9+x)
55-x = 27+3x
55-27=3x+x
4x = 28
x= 7
therefore number of shells zoe gives to dev = 7
number of shells zoe is left with = 55-7= 48
number of shells dev has = 9+7=16

Find the maximum value of P=3x+2y subject to the following constraints:
Please help me!!!
Answer:
maximum value of P is 33
Step-by-step explanation:
Sketch the lines represented by the constraints
5x + y = 16
with intercepts ([tex]\frac{16}{5}[/tex], 0) and (0, 16)
2x + 3y = 22
with intercepts (11, 0) and (0, [tex]\frac{22}{3}[/tex])
The solutions to both are below the lines.
Solve 5x + y = 16 and 2x + 3y = 22 simultaneously to find the point of intersection at (2, 6)
The coordinates of the vertices of the feasible region are
(0, 0), (0, 16), (2, 6), 11, 0)
Evaluate the objective function at each vertex
P = 3(0) + 2(0) = 0 + 0 = 0
P = 3(0) + 2(16) = 0 + 32 = 32
P = 3(2) + 2(6) = 6 + 12 = 18
P = 3(11) + 2(0) = 33 + 0 = 33
The maximum value of P is 33 when x = 11 and y = 0

The average height of a giraffe and a baby giraffe is 6m. If the baby giraffe has a height which is 2/3 that of the giraffe, what is the height of the baby giraffe?
To find the height of the baby giraffe given the average height of it and a giraffe is 6m, and it is 2/3 the giraffe's height, first solve for the giraffe's height to find it is 7.2m. Then, calculate 2/3 of this to get the baby giraffe's height, which is 4.8m.
Explanation:The question asks to determine the height of a baby giraffe given the average height of a giraffe and a baby giraffe together is 6m, and the baby giraffe's height is 2/3 that of the giraffe's height. Let X be the height of the giraffe. Then, the baby giraffe's height would be 2/3 X. Given the average of these two heights is 6m, the equation to find the height of the baby giraffe is:
(X + (2/3)X) / 2 = 6
By solving this equation:
First, find a common denominator to add X and 2/3 X, which gives us (3/3)X + (2/3)X = (5/3)X.Then, multiply both sides by 2 to eliminate the division by 2, resulting in (5/3)X = 12.Finally, multiply each side by 3/5 to solve for X, which gives X = 12 * (3/5) = 7.2m.Since the baby giraffe is 2/3 the height of the giraffe, its height is 2/3 * 7.2 = 4.8m.Hence, the height of the baby giraffe is 4.8m.

Which ordered pair is a solution of the equation?
-3x+4y=14
A- Only (2,5)
B- Both (2,5) and (4,6)
C-Neither
Final answer:
The ordered pair (2,5) satisfies the equation -3x+4y=14, making it the correct solution, while the ordered pair (4,6) does not satisfy the equation.
Explanation:
To determine which ordered pair is a solution to the given linear equation -3x+4y=14, we need to plug in the x and y values from each pair into the equation and see if the equation holds true.
For the ordered pair (2,5), substituting x with 2 and y with 5 gives us:
-3(2) + 4(5) = -6 + 20 = 14Since the equation is satisfied, (2,5) is a solution to the equation.
For the ordered pair (4,6), substituting x with 4 and y with 6 gives us:
-3(4) + 4(6) = -12 + 24 = 12Since -12 + 24 does not equal 14, the equation is not satisfied, and hence, (4,6) is not a solution to the equation.
Therefore, the correct answer is A- Only (2,5)
