What shapes do I need to use to find the surface area? (How many of each shape)
Answer:
Area of Plane Shapes-
1. Triangle Area = ½ × b × h b = base h = vertical height
2. Square Area = a2 a = length of side
Step-by-step explanation:
The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for which the surface area is the sum of the areas of its faces. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces. This definition of surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration. Surface area is the total amount of space that all of the surfaces of an object take up. It is the sum of the area of all the surfaces of that object.[1] Finding the surface area of a three-dimensional shape is moderately easy as long as you know the correct formula. Each shape has its own separate formula, so you'll first need to identify the shape you’re working with. Memorizing the surface area formula for various objects can make calculations easier in the future. Here are a few of the most common shapes you might encounter.

Define the formula for surface area of a cube.
2
Measure the length of one side.
3

Find the mean of the data set {4.5,5, 3.5, 2, 2.5}.
So what is the answer ;, I nordeste im
Answer:
Mean = 3.5
Step-by-step explanation:
The given data is :
4.5,5, 3.5, 2, 2.5
We need to find the mean of the given data.
We know that,
Mean = sum of observations/total no. of observations
Here,
Total no. of observations = 5
Sum of observations = 4.5 + 5+ 3.5+ 2+ 2.5 = 17.5
Mean,
[tex]m=\dfrac{17.5}{5}\\\\m=3.5[/tex]
Hence, the mean of the data set is equal to 3.5.

Answer:
6 is the Answer.Step-by-step explanation:
A fraction consists of two parts the top number and the bottom one.
Think of the top number as the count and the bottom as the size indicator. So you have:
countsize indicator −−−−−−−−−−→proper names numeratordenominator
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Consider the action example of dividing 3 into 6.
We can do this division directly because their size indicators are the same. That is, we have: 61÷31. People do not normally write it this way but it is correct.
To directly divide the counts the size indicator must be the same
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So we need to see how many of 18 will fit into 34
We can not do this directly in one operation as the size indicators are not the same.
Lets make the size indicators (denominators) the same
Multiply by 1 and you do not change the value but
1 comes in many forms.
[34×1]÷18 → [34×22]÷18
[3×24×2]÷18 → 68÷18
Now that the size indicators (denominators) are the same we can just divide the counts (numerators)
countsize indicator→[68÷18]=6÷1=6
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There is 12 feet from the center of the room to the wall. How big is the floor? (JUST write the number: no units) *
Answer:
im gonna say 24
Step-by-step explanation:
Answer:
if the room is a square it would be 576 if it is 12 feet from the center of the room to the edge than if you make another line from the center to the opposite direction of the first line and push your new line to the edge of the room you would get 24 feet from one corner to another and if the room is a square then all sides will be the same length so all sides will be 24 feet. and the equation would be 24 times 24 and the answer to that equation would be 576A farmer is monitoring the water content of the soil during a dry summer.

What is the area of the figure at the right?
A 80 in.2
C 96 in 2
B 88 in.2
D 120 in.2
Answer: 88 in2
Step-by-step explanation:
16 * 4 = 64
8 * 3 = 24 / 2 = 12
12 + 12 + 64 = 88
The area of the figure is 88 square inch.
Thus, option (B) is correct.
To find the Area of given, divide the figure into 3 parts.
The formula used here are:
Area of rectangle = length x widthArea of Triangle = 1/2 x base x height1. Area of Rectangle whose length = 16 inch and width is 4 inch
= 16 x 4
= 64 square inch
2. Area of Triangle whose base = 8 inch and height= 3 inch
= 1/2 x 8 x 3
= 4 x 3
= 12 square inch
3. Area of Triangle whose base = 8 inch and height= 3 inch
= 1/2 x 8 x 3
= 4 x 3
= 12 square inch
Now, the total Area of figure
= Area of Rectangle + Area of Triangle + Area of Triangle
= 64 + 12 + 12
= 64 + 24
= 88 square inch.
Thus, option (B) is correct.

Supongamos que un restaurante ofrece 5 entradas, 4 platos principales y 3 postres. ¿De
cuántas formas un cliente puede ordenar una comida?
Answer:
El cliente puede ordenar una comida en 60 formas distintas.
Step-by-step explanation:
El cliente escoge una entrada de las cinco opciones disponibles, luego un plato principal de cuatro opciones disponibles y un postre de tres opciones disponibles. Es costumbre consumir primero una entrada, después un plato principal y finalmente, un postre.
Estadísticamente hablando, se debe considerar un producto de tres combinaciones, puesto que el orden no importa a la hora de pedir, como sigue:
[tex]n = _{5}C_{1}\times _{4}C_{1}\times _{3}C_{1}[/tex] (1)
Donde:
[tex]n[/tex] - Total de combinaciones al ordenar una comida (entrada, plato principal, postre)
[tex]_{5}C_{1}[/tex] - Combinaciones posibles para pedir una entrada.
[tex]_{4}C_{1}[/tex] - Combinaciones posibles para pedir un plato principal.
[tex]_{3}C_{1}[/tex] - Combinaciones posibles para pedir un postre.
Ahora, desarrollamos la operación:
[tex]n = \frac{5!}{(5-1)!}\times \frac{4!}{(4-1)!} \times \frac{3!}{(3-1)!}[/tex]
[tex]n = 5\times 4\times 3[/tex]

An Angle measures 64 more than the measure of its supplementary angle what is the measure of each angle
Answer:
Original angle = 122*
Supplementary angle = 58*
Step-by-step explanation:
A supplementary angle is one of two angles that make up 180*
If one angle is 30*, its supplementary angle is 150*. 30 + 150 = 180.
So in this case we have two angles, the original and the supplementary angle. The original angle is 64* more than the supplementary angle. The key word is MORE.
The formula to figure it out would look like this: x + (x + 64) = 180
x is the supplementary angle
x + 64 is the original angle (64 MORE than its supplementary angle)
180 is the total measure of the two angles because they are supplementary and we know that supplementary angles always equals 180* when added together.
Take the formula and do a little algebra.
x + (x + 64) = 180
Subtract 64 from both sides
x + x = 116
Combine the x's
2x = 116
Divide both side by 2
x = 58
Remeber we know that the original angle is 64 more than the supplementary angle, so we'll add the 64 to the value of x and we get 122.
x + 64 = 122
Check our work:
x + (x + 64) = 180
58 + 58 + 64 = 180
Given :
An angle which measures 64° more the measure of its supplementary angle.⠀
To Find :
The measure of its supplementary angle.⠀
Solution :
Let's assume the one of the supplementary angle as x and the other angle as (x + 64)° .Now,
⠀
According to the Question :
⠀
[tex]\longrightarrow\qquad \sf{{x + (x + 64) {}^{ \circ} = {180}^{ \circ} }}[/tex]
⠀
[tex]\longrightarrow\qquad \sf{{x + x + 64 {}^{ \circ} = {180}^{ \circ} }}[/tex]
⠀
[tex]\longrightarrow\qquad \sf{{2x + 64 {}^{ \circ} = {180}^{ \circ} }}[/tex]
⠀
[tex]\longrightarrow\qquad \sf{{2x = {180}^{ \circ} - 64 {}^{ \circ}}}[/tex]
⠀
[tex]\longrightarrow\qquad \sf{{2x = {116}^{ \circ} }}[/tex]
⠀
[tex]\longrightarrow\qquad \sf{{x = \dfrac{{116}^{ \circ}}{2} }}[/tex]
⠀
[tex]\longrightarrow\qquad \mathfrak{\pmb{{x = {58}^{ \circ} }}}[/tex]

Andrea has 4 hours to spend training for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same distance to cool down. If she runs at a speed of 8mph and walks back at a speed of 2mph, how long should she plan to spend walking back?
Answer:
Time spend in walking = 3.2 hour = 3¹/₅ hour
Step-by-step explanation:
Given:
Total time taken = 4 hour
Speed when run = 8 mph
Speed when walk = 2 mph
Find:
Time spend in walking
Computtaion:
We know that;
Time = Distance / Speed
Assume;
One side distance = D
So,
D/8 + D/2 = 4
2D + 8D = 64
10D = 64
D = 6.4
So,
One side distance = 6.4 mile
Time spend in walking = One side distance / Speed when walk
Time spend in walking = 6.4 / 2
Time spend in walking = 3.2 hour = 3¹/₅ hour
A classroom has a length of 20ft. And a width of 30ft. The flooring is to be replaced by tiles. If each tile has a length of 24 in and a width of 36 in, how many tiles are needed to cover the classroom?
Answer:
100
Step-by-step explanation:
first we need to turn the feet into inches
20x12=240
30x12=360
now to get the area of the floor we need to do 360x240=
86,400
now the area of each tile is 24x36=864
now to find out how many tiles fit on the floor we need to do 86,400 divided by 864 which = 100
∠A and \angle B∠B are complementary angles. If m\angle A=(2x-4) ∘ and m\angle B=(5x+17) ∘ , then find the measure of \angle A∠A.
Answer: 18°
Step-by-step explanation:
Complementary angles are the angles that when we add them together, the value will equal 90°.
In this question, we've to add both angles and equate them to 90°. This will be:
(2x - 4) + (5x + 17) = 90
2x - 4 + 5x + 17 = 90
Collect like terms
2x + 5x = 90 + 4 - 17
7x = 77
x = 77/7
x = 11
Angle A will be:
= (2x-4)
= 2(11) - 4
= 22 - 4
= 18°
