Find the surface area, in square inches, of a cube whose volume is 8 in³.
Answer:
24 in^2
Step-by-step explanation:
common math
Answer:
Surface area of cube is 24 in²Step-by-step explanation:
In this question we have given volume of cube that is 8 in³. But we know that volume of cube is a³. So ,
[tex] \implies \: a {}^{3} = 8[/tex]
Now ,
[tex] \implies \: a = \sqrt[3]{8} [/tex]
So , cube root of 8 is ,
[tex] \implies \: \boxed{\bold{a = 2}}[/tex]
Therefore, value of a is 2 inches .Now , we are finding surface area of cube . We know that surface area of cube is 6a² . So ,
6 ( 2 )²6 ( 4 )24[tex] \pink{ \boxed{ Therefore, \: surface \: area \: of \: cube \: is \: 24 \: in ^{2} }}[/tex]
#Keep LearningFactor the trinomial 6x²-5x-6, then find the sum of the factors.
Answer:
5x - 1
Find Factors:
6x²-5x-66x²-9x+4x-63x(2x-3)+2(2x-3)(2x-3)(3x+2)Factors: (2x-3)(3x+2)
Their sum:
(2x-3)+(3x+2)2x + 3x -3 + 25x - 1Factor the trinomial 6x²-5x-6, then find the sum of the factors .
Given : -An equation = 6x² - 5x - 6To Find : -Sum of their factors .Concept : -This question belongs to factorising the trinomial with the help of different methods such as middle term splitting .
Solution : -[tex] \longrightarrow \: 6x {}^{2} - 5x - 6[/tex]
Now , by splitting the middle term that is - 5 x :
[tex] \longrightarrow \: 6x {}^{2} - 9x + 4x - 6[/tex]
Now , taking 3x and -2 as common :
[tex] \longrightarrow \: 3x(2x - 3) + 2(2x - 3)[/tex]
So ,
[tex] \longrightarrow \: ( 3x + 2 ) ( 2x - 3 )[/tex]
Therefore , factors are ,
( 3x + 2 )( 2x - 3 )In the question we have ask to find the sum of their factors . So adding them ,
3x + 2 + 2x - 35x - 1Therefore , 5x - 1 is the sum of the factors .

In your own words describe how you would find the volume of a
figure using unit cubes?
Answer:
Volume = length x width x height.
You only need to know one side to figure out the volume of a cube.
The units of measure for volume are cubic units.
Volume is in three dimensions.
You can multiply the sides in any order.
Which side you call length, width, or height doesn't matter.
Answer: Volume = length x width x height.

George started a coin collection. His dad gave him 75 coins. Each month he will add 20 coins to the collection. Which equation can be used to find y, the total number of coins in George's collection after x months?
A y= 75x + 20
B y = 20x + 75
C y = 75x - 20
D y=20x - 75
option B
hope it helps...!!!
Answer:
Option B!
Step-by-step explanation:
x = amount of months.
Each month = + 20 coins.
*Each month x amount of months = y*
so 20x + 75(Coins dad gave)
If w = 7 feet, x = 6 feet, y = 13 feet, and z = 8 feet, what is the area of the object?
Answer:
The Area is: 84ft
Step-by-step explanation:
multiply "Y" and "X" and you get 78ft.
"W" + "?"= "Y" If "W"=7, what is 13 ("Y") - 7? 13 -7=6. so "?"=6.
"Z"-"X"="?" "Z"=8 and "X"=6. so 8-6=2
2x6=12 *but remember that to find the area of a triangle it is half of a square of rectangle so you have to divide it in half. 12/2=6.
78+6=84.

Are multiplication and division of unit fractions related? Describe the relationship you see. BRAINLIEST HERE
Step-by-step explanation Hope this help a'lot
Multiplication and division both need to have a common denominator or else you would get an incorrect answer. Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators."

Step-by-step explanation:
(x,y) so 7 is the x and 8 is the y.
In the diagram, AB, BC, CD, DE, EF, FG, GH, and HK all have lengths 4, and all angles are right angles, with the exception of the angles at D and F.
Determine the length of DF.
Answer:
5.66 length (3s.f.)
Step-by-step explanation:
[tex] \sqrt{4 {}^{2} + 4 {}^{2} } [/tex]
= 5.65685
= 5.66 (3 s.f.)
By using the Pythagorean theorem, we will see that the length of DF is 5.7 units.
How to get the length of DF?
We can make a right triangle with the sides: DE, FE, and DF.
Such that we know that:
DE = FE = 4
These two are the cathetus of the right triangle.
Then DF is the hypotenuse.
Now, remember the Pythagorean theorem, it says that the sum of the squares of the cathetus is equal to the square of the hypotenuse, then we have:
(DE)^2 + (FE)^2 = (DF)^2
4^2 + 4^2 =(DF)^2
√32 = DF = 5.7
The length of DF is 5.7 units.

Let's start with 5 squared. 5 squared, or just squared in general, represents the number behind it times itself.
[tex]5^2~or~ 5*5 = 25[/tex]
Now, add 3
[tex]25 + 3 = 28[/tex]
Next, subtract 1
[tex]28 - 1 = 27[/tex]
Now, you must divide, because the line under the first equation represents division, or a fraction. For this case, division. Before dividing your result, 27, by y, the second equation, you first want to solve equation 2, y.
[tex]\frac{18}{2} = 9[/tex]
Lastly, divide x by y, 27 divided by 9

△ABC has interior angles with measures x°, 100°, and 70°, and △DEF has interior angles with measures y°, 70°, and 50°.
Using the given information, which statement is true?
The two triangles are not similar because x≠y .
The triangles are similar because they each have an interior angle with a measure 70°.
The two triangles are not similar because the interior angles are congruent but the side lengths are different.
The two triangles are not similar because y = 60 so it is impossible to have three congruent angles.
Answer:
Now, △DEF has interior angles with measures y°, 70°, and 20°.
By using angle sum property,
Now, we can say that,
"The two triangles are not similar because x≠y"
As one angle of measure 70 degree is common in both the triangles.
If 'x' would be equal to 'y' , then we could say that the triangles are similar by AA criteria.
Therefore, the two triangles are not similar because x is not equal to
Step-by-step explanation:
Answer:
the triangles are not similar. If they were, they would have the same angles.
The interior angles are not congruent. We can rule out choice B and C.
Just because they have one equal angle does not make them similar. We can rule out D.

At thanksgiving, Helen's Pie company sells pies.
Hellen would like to roll and cut out the correct amount of dough for the top crust of this pie. What is the AREA of the dough she will need? Use 3.14 as pi.
Also the diameter is 4 inches
Answer:
12.56 in²
Step-by-step explanation:
Area = πr²
Substitute for pi.
A = 3.14 × r²
The diameter is 4. We divide the diameter by 2 to get the radius.
4 ÷ 2 = 2
Substitute for the radius.
A = 3.14 × 2²

A figure is shown.
What is the value, in degrees, of xx?
Answer:
x = 44.3
Step-by-step explanation:
Knowing that the given figure shows a supplementary angle
⇒ Note that: Supplementary angle= 180 °
Since it already given the other two number
The equation is:
43 + 92.7 + x = 180
Adding both number together : 43 + 92.7
135.7 + x = 180
Subtract 135.7 from both sides
135.7 -135.7 +x = 180-135.7
x = 44.3
Hence, the value in degrees of x = 44.3 °

Answer:
Tbh I am not sure but it's a semi-circle prism or like semi cylinder (I think) but usually semi-circles themselves will not tessellate bc circles have no angles and when u line them up next to each other there will be gaps between them and one of the tessellation rules is that no overlapping or gaps so yeah
I am sorry lol if that's all wrong but my answer is no, I don't think that this figure is a tessellate plane
