Answer:
Surface Area varies by object/shape.
Ask your teacher/learning helper for those formulas of surface area
Step-by-step explanation:
Surface area is the sum of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
A student has a rectangular photograph with side lengths of 5 inches and x inches The area of the rectangle is 33 square inches. The student wants to reduce the size of the photograph so that each side length is of its original length. The photograph will be printed on paper that costs $0.16 per square inch. What will be the cost of the paper needed to print the reduced photograph?
Answer:
1.32
Step-by-step explanation:
total area = 33
33/5 1/2 = 6 . X=6
5 1/2 x 1/2 = 2.75 . 6 x 1/2 = 3
2.75 x 3 = 8.25
new area = 8.25
8.25 x .13 = 1.32

The length of a rectangle is five more than three time its width. The perimeter of a rectangle is 234. What is the width of the rectangle
Answer:
28 units
Step-by-step explanation:
Given data
Let the width be x
The length is =3x+5
Perimeeter= 234
The expression for the perimeter is
P=2L+2W
Substitute
234= 2*x+2(3x+5)
234= 2x+6x+10
Collect like terms
234= 8x+10
234-10= 8x
224=8x
x= 224/8
x=28
Hence the width is 28 units

The Spirit Team will be selling popcorn as a fundraiser at the next basketball game to earn funds to go to Orlando for a competition. If they need the volume of the popcorn container to be under 220 cubic inches per serving, select all of the following dimensions of a cylinder they could use.
3 inch radius and 4 inch height
4 inch radius and 4 inch height
9 inch radius and 9 inch height
4 inch diameter and 9 inch height
6 inch diameter and 9 inch height
9 inch diameter and 4 inch height
Answer:A and b
Step-by-step explanation:
The dimensions of cylinders that have a volume under 220 cubic inches per serving are:
3-inch radius and 4-inch height
4-inch diameter and 4-inch height
4-inch diameter and 9-inch height
Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
Here,
We can use the formula V = πr²h to find the volume of each cylinder.
For a cylinder with a 3-inch radius and 4-inch height:
V = π(3)²(4) ≈ 113.1 cubic inches
For a cylinder with a 4-inch radius and 4-inch height:
V = π(4)²(4) ≈ 200.96 cubic inches
For a cylinder with a 9-inch radius and 9-inch height:
V = π(9)²(9) ≈ 2289.0 cubic inches
For a cylinder with a 4-inch diameter and 9-inch height (radius is 2 inches):
V = π(2)²(9) ≈ 113.04 cubic inches
For a cylinder with a 6-inch diameter and 9-inch height (radius is 3 inches):
V = π(3)²(9) ≈ 254.5 cubic inches
For a cylinder with a 9-inch diameter and 4-inch height (radius is 4.5 inches):
V = π(4.5)²(4) ≈ 254.5 cubic inches
Therefore, the dimensions of cylinders that have a volume under 220 cubic inches per serving are:
3-inch radius and 4-inch height
4-inch diameter and 4-inch height
4-inch diameter and 9-inch height

Step-by-step explanation:
River C is 400 miles longer than River D. If the sum of their lengths is 5560 miles, what is the length of each river?
Answer:
River D - 2580 miles
River C - 2980 miles
Step-by-step explanation:
Let the length of River D be represented with x
length of river C = 400 + x
total length of both rivers = 5560
x + 400 + x = 5560
2x + 400 = 5560
collect like terms
2x = 5560 - 400
2x = 5160
divide both sides of the equation by 2
x = 5160 / 2
x = 2580
length of river c = 400 + 2580 = 2980

Answer:
12 possible roots
Step-by-step explanation:
we can use the rational zeros theorem which says that in order to find the possible roots for a polynomial we need to divide the factors of the constant by the factors of the coefficient of the leading term
which in this case is:
±(1, 2, 3, 4, 6, 12)/(1)
±1, 2, 3, 4, 6, 12
so we have 12 possible roots
Good art is art that allows you to enter it from a variety of angles and to
emerge with a variety of views."" what is you insights about this quotes?
Answer:
Step-by-step explanation:
My insight on this quote is that a good piece of art can tell various stories. Maybe there are various characters in the art and each on shows different actions and emotions. Or maybe the art is abstract and the emotions that it triggers in a person can tell a story all on its own. In a way these various angles are the different ways that the art makes us feels that allows us to view it in such a way. Yet these views can change if we look at the art in a different perspective.

a triangle equals 180 with all the degrees added together :)
The base angles of an
isosceles triangle
Measure (2x+40)° and
(5x+16)". find x and the
Measure of both angles.
Answer:
71
93.5
x=15.5
Step-by-step explanation:
(2x+40)+(5x+16)+(x)=180
you have to put all the measures together and equal it to 180. when it comes to triangles, all the angles added together are equal to 180.
now solve the equation and you should get this:
x=15.5
the next step is to solve the give equations separately:
2(15.5)+40=71
5(15.5)+16=93.5
(15.5)=15.5
now to check the work, you have to add all the measures that were just calculated:
71+93.5+15.5=180 so check!
