Which are perfect cubes? Check all that apply.

64
x16
8x3
27x4
81x6
125x9

and pls tell me how to find a perfect cube i will mark brainlyesr

Answer:

y=x-4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)=(4-(-2))/(8-2)=(4+2)/6=6/6=1

slope is 1

y-y1=m(x-x1) where m=slope

y-(-2)=1(x-2)

y+2=x-2

y=x-2-2

y=x-4

Answer:

27

Step-by-step explanation:

a+b/2 times h

thats teh formula for the area of a trapezoid so a and b are the top and bottom sides of the trapezoid

so 6 on the bottom and 3 on the top

add those and it equals 9 then divide by 2 gives us 9/2

then the height would be 6

so we multiply 9/2 by 6 giving us 54/2

simplified equals 27 so ur answer would be 27 units squared

Answer:The perimeter of a rectangular atrium is 27 yards in width and 123 yards in length.

Step-by-step explanation:

Step 1

The perimeter of a rectangular atrium is given as 2( l+b)

The perimeter of a rectangular atrium is 300 yards.

Let the width be represented as x

such that the

The length of the garden which is ninety-six yards more than the width is expressed as x+ 96

and the expression to solve for length and width will now be

Step 2

Perimeter = 2(l+b) = 2l + 2b

300=2( x+96) + 2 x

300= 2x+ 192 + 2x

300= 192+ 4x

300-192=4x

108=4x

x=108/4

x=27

width = 27 yards

length = x+ 96= 27 +96=123 yards

Answer:

0.056

Step-by-step explanation:

For decimals, you just multiply, and the hundredths would stay, so the answer is 0.056, because 8 x 7 = 56!

Answer:

0.056

Step-by-step explanation:

7*8 is 56 right

looking at 0.7 how many numbers are before that dot

1 right which is seven

then 0.08 has how many digits before the dot thing

2 right which is 0 and 8

in total making three

then in 56 move three times forward from behind

1  5.6

2  0.56

3  0.056

and thats how we got this

dont confuse this technique with numbers like 0.80

the zero at the end of that number is not needed

that is to say that

0.80 = 0.8

when theres a zero at the back of a decimal its not counted

e.g

0.50= 0.5

0.4000000= 0.4

Answer:

[tex]A_1 = 24m^2[/tex] -- Swing set

[tex]A_2 = 16m^2[/tex] -- Slide

[tex]A_3 = 5m^2[/tex] --- Pathway

Step-by-step explanation:

Missing part of the question:

Fill in the table above to show the area of each section (see attachment for table)

The area of each section is calculated as:

[tex]Area = Length * Width[/tex]

For the Swing set

[tex]A_1 = 8m * 3m[/tex]

[tex]A_1 = 24m^2[/tex]

For the Slide

[tex]A_2 = 8m * 2m[/tex]

[tex]A_2 = 16m^2[/tex]

For the Pathway

[tex]A_3 = 5m * 1m[/tex]

[tex]A_3 = 5m^2[/tex]

The total area is:

[tex]Area=A_1 + A_2 + A_3[/tex]

[tex]Area = 24m^2 + 16m^2 + 5m^2[/tex]

[tex]Area = 45m^2[/tex]

The answer is 3.2. If you subtract 10.3 and 7.1, then you get 3.2.

Answer:

2/5 < 1/2

Step-by-step explanation:

First, find the LCM for both denominators because you can't multiply 2 to get to 5. The LCM of 5 and 2 are 10, so you put that as their denominator. Then you have to think what you multiplied by 5 or 2 to get 10. For 2/5, you multiplied 5 by 2 to get 10, so multiply the numerator by 2 too. For 1/2, you multiplied 2 by 5 to get 10, so multiply the numerator by 5. Now, you will have 4/10 and 5/10. It's pretty obvious that 5/10 is bigger than 4/10, so the correct answer is 2/5 < 1/2

36x + 324 - 28x + 196

combine like terms: 36x - 28x = 8x and 324 + 196 = 520

8x+520

Answer:

200,000 feet to dig

Step-by-step explanation:

We use a ratio for this problem

30,000         200,000,000

-----------   =   ---------------------

30                        x

200,000,000 * 30

----------------------------  = 200,000 feet to dig

30,000

This answer is reasonable because 200,000,000 years ago was a long time ago so then the person must dig a reasonable amount of dirt. So then 200,000 feet is reasonable.

Answer: Each piece is 1 2/3 inch length.

Step-by-step explanation:

Total length of cookie dough =10-inch

Since it is being into divided  into 6 equal-length pieces

We have that each piece will have=1 0-inch / 6 = 5/3 = 1 2/3 inch length.

Answer:

x1 = 2, x2 =-8

y1=-2, y2 =-2

y2-y1 = |-2+2| =0

x2-x1= |-8-2|= 10

x = 12 /cos 36°

Answer: The acute angle ∠YXZ = 24.3°.

Step-by-step explanation:

If in triangle ABC, C is the angle included between sides a and b then

Area of triangle = [tex]\dfrac12a\cdot b\cdot sin C[/tex]

here, XZ = 21.5cm and XY = 13.5cm are sides that includes acute angle ∠YXZ..

Area of a triangle = 59.7cm²

then, as per given, we have

[tex]59.7=\dfrac12(21.5)(13.5)\ \sin X\\\\\Rightarrow\ 59.7=145.125\ \sin X\\\\\Rightarrow\ \sin X = \dfrac{59.7}{145.125}\\\\\Rightarrow\ \sin X =0.41137\\\\\Rightarrow\ X = \sin ^{-1}(0.41137)\approx24.3^{\circ}[/tex]

Hence, the acute angle ∠YXZ = 24.3°.

Answer:

19 units

Step-by-step explanation:

Perimeter of the rectangle = 124 units

width = x units

length = 5 + 2x units

The perimeter of a rectangle is given by;

P = 2(l + b)

Substituting values;

124 = 2[(5 + 2x) + x]

124 = 2[5 + 3x]

124 = 10 + 6x

124 - 10 = 6x

114 =6x

x= 114/6

x = 19

width = 19 units
