Answer:
600
Step-by-step explanation:
10 times 10 is 100. A cube has 6 sides. 6 times 100 is 600
Answer:
10 x 10 = 100 so the area of 1 side is 100
there is 6 sides and the surface area is all the areas added up
100 x 6 = 600
the surface area is 600

The length of a rectangle is six times its width.
If the perimeter of the rectangle is 112 ft, find its area.
Answer:
Area = 48*8=384 sq. in
Step-by-step explanation:
Perimeter = 112
Length 6x
Width =x cm
Perimeter = 2(6x+x)
Perimeter = 14x
112 = 14x x=
8 in Width
Length = 6*8=48 in
Area = 48*8=384 sq. in
Did this kinda fast but I hope it helped XD
Length of the rectangle = 48ft
Width of the rectangle = 8ft
Area of rectangle = 384 ft²
What is rectangle?Rectangle is a shape with four straight sides and four angles of 90 degrees (right angles). Two of the sides are longer than the other two.
Given,
Length of a rectangle is six times its width
Let width is x then length is 6x
Perimeter of rectangle = 112 ft
Perimeter of rectangle = 2(Length + Width)
2(Length + Width) = 112
2(x + 6x) = 112
7x = 56
x = 8
Width = 8 ft
Length = 6 × 8 = 48 ft
Area of rectangle = length × width
= 48 × 8
= 384 ft²
Hence, 8ft is width and 48ft is length of the rectangle. 384 ft² is the area of rectangle.

110 is half of 220.
Here, we have,
To find half of a number, you divide it by 2.
In this case, to find half of 220, you divide 220 by 2:
220 ÷ 2 = 110
Therefore, half of 220 is 110.
When we divide 220 by 2,
we are splitting it into two equal parts, with each part being 110.
so, we get,

A point with a positive X coordinate and a negative Y coordinate is reflected over the Y axis which sentence describes the coordinates the new point
Answer:
negative X coordinate and a negative Y coordinate.
Step-by-step explanation:
positive X coordinate and a negative Y coordinate is reflected over the Y axis.
Anything reflected over the Y axis doesn't usually change the y coordinate. So it's negative X coordinate and a negative Y coordinate.

a circle is centered at (-4,9)and has a radius of 11. what is the equation of the circle. use x and y
Answer:
(x + 4)^2 + (y-9)^2 = 121
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 + (y-k) ^2 = r^2 where (h,k) is the center and r is the radius
(x - -4)^2 + (y-9)^2 = 11 ^2
(x + 4)^2 + (y-9)^2 = 11 ^2
(x + 4)^2 + (y-9)^2 = 121

Answer:
area is 24
Step-by-step explanation:
The function g(n) = n2 − 16n + 69 represents a parabola.
Part A: Rewrite the function in vertex form by completing the square. Show your work. (6 points)
Part B: Determine the vertex and indicate whether it is a maximum or a minimum on the graph. How do you know? (2 points)
Part C: Determine the axis of symmetry for g(n). (2 points)
Answer:
Step-by-step explanation:
A) y + ? = n^2 - 16n + ? + 69
y + 64 = n^2 -16n + 64 + 69
y + 64 = (n-8)^2 + 69
y = (n-8)^2 + 5
B) vertex is (8,5) because the value of a vertex is always (h,k) from the parent vertex function:
y = a(x-h) + k
it's a minimum only because the (a) value is positive
C) axis of symmetry = 8

[tex]\dfrac{\frac{y(y+1)}{y(y-2)}}{\frac{4(y+1)}{(y-2)^2}}=[/tex]
Now, you can cancel out some terms:
[tex]\dfrac{\frac{y+1}{y-2}}{\frac{4(y+1)}{(y-2)^2}}=[/tex]
Now, when you divide a fraction by another fraction, that is the same as multiplying the first fraction by the reciprocal of the second one:

[tex]\frac{y-2}{4}[/tex]

Find the equation of the line that passes through (-4, 8) and has a slope of -3.
Answer:
y= -3x-4
Step-by-step explanation:
Since we already know the slope, we have to plug in values to find out the constant of the equation. We use the point given to figure it out. Y+8 and x=-4, therefore 8=-3(-4)+c ---> 8=12+c. C=-4
If the sum of 4040 consecutive integer numbers is 2020, find out the absolute difference between the first number and the last number.
Let [tex]x[/tex] be the smallest of the consecutive integers summing to 2020. Then the largest integer in the sum is [tex]x+4039,[/tex] so our answer is [tex]\boxed{4039}.[/tex]
For completeness, though, let's solve for the value of [tex]x[/tex] that satisfies the conditions of the problem. Recall that the sum of an arithmetic series with first term [tex]a_1,[/tex] last term [tex]a_n,[/tex] and [tex]n[/tex] terms, is [tex]\frac{n(a_1+a_n)}{2}.[/tex] Plugging in our known values gives us the equation [tex]\frac{4040(2x+4039)}{2}=2020,[/tex] which simplifies to [tex]2x+4039=1.[/tex] Thus, [tex]x=-2019,[/tex] so the 4040 consecutive integers are [tex]-2019,-2018,\dots,-1,0,1,\dots,2018,2019,2020.[/tex] Notice how everything except the [tex]2020[/tex] cancels out!
A glass ball is packed in the box shown. Which expression represents the volume of foam padding needed to fill the space in the box around the sphere in terms of Pi
Answer: (27- 4/3 pi) r^3
Step-by-step explanation: 1. Volume of a cube: V= a^3, V= 3^3 , V=27
2. Volume of a sphere: V=4/3 pi r^3 ......
The expression which represents the volume of the foam padding needed to fill the space in the box around the sphere in terms of π is option C. (27 - [tex]\frac{4}{3}[/tex] π) r³.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
We have a sphere of radius r inside a cube of side length 3r.
Volume of a cube = (a)³, where a is the side length.
Here a = 3r
Volume of the cube = (3r)³ = 27r³
Volume of a sphere of radius r = [tex]\frac{4}{3}[/tex] π r³
Volume of the foam padding needed to fill the space in the box around the sphere = 27r³ - [tex]\frac{4}{3}[/tex] π r³
= r³ (27 - [tex]\frac{4}{3}[/tex] π)
Hence the volume of the space inside the cube outside the sphere is r³ (27 - [tex]\frac{4}{3}[/tex] π).
