a squared paper shows the nets of cuboid A and cuboid B. do the two cuboids have the same surface area? plzzzzzzzzz answer
Answers
Answer:
No it doesn't have the same surfaces
The cuboid A and B have different surface areas.
What is surface area?The surface area of a three-dimensional object is the total area of all its faces.
Formula for the surface area of cuboidSA=2lw + 2lh + 2hw
Where,
SA is the surface area of a cuboid
l is the length of the cuboid
h is the height of the cuboid
w is the width of the cuboid
Let the area of each cube is one unit.
So, for the cuboid A
Length = 3 unit
Width = 2 unit
Height = 3 unit
Therefore, the surface area of cuboid A = ( 3 × 2 + 3 × 2 + 2 × 2 ) 2
⇒ Surface area of cuboid A = 32 square unit
For cuboid B
Length = 4 unit
Width = 1 unit
Height = 3 unit
Therefore,
The surface area of cuboid B = (4 × 1 + 4 × 3 + 3 × 1)2
⇒ Surface area of cuboid B = 38 square unit
Hence, the cuboid A and B have different surface areas.

Which best describes the relationship between the line that passes through the points
Answers
Answer:
Perpendicular (A)
Step-by-step explanation:
First find the gradient of the first line:
Change in y/ Change in x = -7-(-2)/ -9-(-12) = -5/3
Now find the gradient of the second line:
9-6/1-6 = -3/-5 = 3/5
When we multiply the gradient of two perpendicular lines we will get:
m1 x m2 = -1
If we multiply 3/5 and -5/3 we will get -1
Therefore it is perpendicular!

Describe any patterns you notice. Are the two expressions ever equal? Can one be greater than the other?
Answers
Answer:
Both expressions are equal. One expression cannot be greater than the others.
Step-by-step explanation:
The given expressions are:
A: (x + y)
B: (x) + (y)
Let x = a and y = bA: (a+b) = a+b
B: (a)+(b) = a+b
Let x = -a and y = -bA: (-a+ (-b)) = -a-b
B: (-a)+(-b) = -a-b
Let x = a and y = -bA: (a+(-b)) = a-b
B: (a)+(-b) = a-b
Let x = -a and y = bA: ((-a)+b) = -a+b
B: (-a)+(b) = -a+b
We can see the pattern that both expressions are always equal to each other, no matter what value of x and y you plug in. One expression cannot be greater than the other

Answers
Answer:
98 degrees
Step-by-step explanation:
The measure of angle 1 is 92°
The correct option is B.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Given:
A transversal intersects 2 lines to form 8 angles.
Clockwise from the top left, the angles are blank, 88 degrees, blank, (7 x + 4) degrees;
blank, blank, (7 x minus 2) degrees, blank.
Now, the property of the supplementary angles:
m∠1 + m∠2 = 180°
m∠1 = 180 - 88
m∠1 = 92°
Therefore, the angle measure of angle 1 is 92°.

You start at (2, 7). You move up 3 units. Where do you end?
Answers
Answer:
(2, 10)
Step-by-step explanation:
Since we are only focusing on vertical movement, we are looking at the y-value. We are moving up 3 units, so we just add 3 to 7 to get 10.
Answer:
2,10
Step-by-step explanation:
The X-axis goes horizontally, and the Y-axis goes vertically, and when doing these coordinate like things, the X-axis goes first, and the Y-axis goes second. So 2 is the X-axis, and 7 is the Y-axis. So if you have to move up 3 units, you have to add 3 to 7, because 7 is vertical and 2 is horizontal.

and what is distance jeremy jumps from the ramp to the fire escape is _______ feet (round to the nearest tenth of a foot)
Answers
Answer:
sin(70°) =10/x
The distance Jeremy jumps from the ramp to the fire escape is 10.6 feet
Step-by-step explanation:
From the question shown in the picture attached, the vertical height Jeremy has to jump is: 15 - 5 = 10 ft
A right triangle is formed, where the angle between the hypotenuse (called x) and one of the legs is: 160° - 90° = 70°, and the vertical height Jeremy has to jump, is the leg opposite to that angle.
From sine definition:
sin(70°) = opposite/hypotenuse
sin(70°) = 10/x
x = 10/sin(70°)
x = 10.6 ft

inequality to determine the range in hours. Show all of your work.
Answers
Answer: A.) 2 <= X <= 5
B.) 48 < = X < = 120
Step-by-step explanation:
Given that a factory can work its employees no more than 5 days a week, that is, less than or equal to 5 days a week
And also, no less than 2 days per week. That is, greater than or equal to 2 day a week.
Let X represent the number of days an employee can work per week.
According to the first statement,
X < = 5
According to the second statement,
X >= 2
An inequality to represent the range of days an employee can work will be
2 < = X <= 5
To represent the range in hours, first convert the number of days to hour
1 day = 24 hours
2 days = 2 × 24 = 48 hours
5 days = 5 × 24 = 120 hours
Therefore, the range will be
48 < = X < = 120

the dead sea is at an elevation of -1,360 feet. A seabirds flying over the dead sea at an elevation of -422 feet. if the bird lands on the dead sea, what will be its change in elevation
Answers
Answer:
- 938
Step-by-step explanation:
We can change these to positive just so its easier to work with
So 1360 - 422 = 938
since they are going down you just have to change the number to a negative.
The change in elevation is 938 feet.
To find the change in elevation.
What is elevation?The action or fact of raising or being raised to a higher or more important level, state, or position. Elevation is distance above sea level. Elevations are usually measured in meters or feet. They can be shown on maps by contour lines, which connect points with the same elevation; by bands of color; or by numbers giving the exact elevations of particular points on the Earths surface.
Given that:
Dead sea is at an elevation = -1,360 feet.
seabirds flying over the dead sea at an elevation =-422 feet.
Although when you have 2 negative numbers in a subtraction-elevation problem, the elevation difference won't be negative.
So, difference between the depth and the surface of the dead sea
= Dead sea is at an elevation - seabirds flying over the dead sea at an elevation
=-1360-(-422)
=-938 feet.
But that would just describe a regular negative subtraction problem, so it becomes 938 feet.
This answer is positive since it describe the distance between these integers.
So, the change in elevation is 938 feet.

b)A trinomial can be a polynomial.
Answers
Answer:a)false.
Sum of 2and p is=2+P
=2+p [since,the value of p is unknown]
Step-by-step explanation:
a) False. The sum of 2 and p is 2+p. We don't have any like terms to combine, so we leave this as is. The sum of two (or more) items is the result of adding them. The expression 2p is the result of multiplying 2 and p. If it said "the product of 2 and p is 2p", then it would be a correct statement.
b) True. Any trinomial is a polynomial, but not the other way around. A polynomial has us sum many monomial terms. A trinomial is a special type of polynomial with exactly 3 terms being added.

x-3 = y
y = x-3
y=-4x-3
We have both equations in slope intercept form
y = mx +b where m is the slope and b is the y intercept
graph is below
They both have the same y intercept so they intersect at (0,-3)
Substitution
x=y+3
y=-4x-3
Substitute the second equation into the first equation
x=y+3
x = -4x-3 +3
x = -4x
Add 4x to each side
5x =0
x=0
y = -4x-3
y = 0-3
y = -3

Additon
x=y+3
Subtract y from each side
x-y = 3
y=-4x-3
Add 4x to each side
4x+y =-3
Add the equations together to eliminate y
x-y = 3
4x+y =-3
