find the surface area of a cube with a side length of 1/9
To find the surface area, we must define what is the surface area
Definition of Surface Area: is all the areas of the sides of the 3D shapes added upIn this case, we have a cube
⇒ which means all the sides have equal areas since all the side lengths
are equal
That means the surface area
⇒ is equal to ⇒ 6 * (Area of One Side)
'6' comes from the # of sides on a cube
Surface Area = [tex]6 *\frac{1}{9} *\frac{1}{9} = \frac{6}{9 *9} =\frac{2*3}{3*3*3*3} =[/tex] 2/27

Answer: Choice C
Mean = 37.1
==================================================
Explanation:
Refer to the table below. The colum labeled "M" is the midpoint for each age interval. To find the midpoint, add up the endpoints and divide by 2. For example, the midpoint of 18 and 24 is (18+24)/2 = 42/2 = 21. Notice how the values of M are increasing by 7 each time.
The column labeled fM refers to multiplying the frequency f with the midpoint M. Example: fM = 6*21 = 126 in the first row.
Add up everything in the column labeled fM and you should get 1484. Divide this over the sum of the frequencies (40) and the mean is 1484/40 = 37.1
Answer:
c is the right answer

What is the price per foot.
Step-by-step explanation:
oh, come on ! you really cannot figure that one out ?
as there are 3 ft in 1 yd, 6 yd are then 6×3 = 18 ft.
so, 18 ft cost $2.88
1 ft costs then 2.88/18 = $0.16
The wheel of a bike has a diameter of 26 inches. What is the circumference of the wheel?
Answer:
C ≈81.64 inches
Step-by-step explanation:
Formula : C ≈ πd
Where:
C = circumference
π ≈ 3.14 {About}
d = diameter
As Given :
Wheel of a bike has a diameter of 26 inches.
Solution:
Note - Given that diameter = 26
π ≈ 3.14 {About}
C ≈ 3.14 (26)
C ≈ 81.64
Therefore the circumference of the wheel is 81.64 inches

How to find the complement of a 58 degree angle
Answer:
32°
Step-by-step explanation:
Complementary angles sum to 90°
the complement of 58° is
90° - 58° = 32°
Complementary angles add up to [tex]\sf{90^\circ}[/tex].
In order to find the complement of the given angle, we should set up the following equation:-
(let n be the unknown angle)
[tex]\sf{n+58=90}[/tex]
Subtract 58 from both sides:-
[tex]\bigstar{\boxed{\pmb{n=32}}[/tex]
Hence, the complement of the angle is 32 degrees.
note:-Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)
1.
y = 4x - 7
4x + 2y = -2
• show your work
• correct X and y
2.
4x^2 + 3 = 39
• show your work
• correct answers
Answer:
1)
x = 1
y = -3
2)
x = 3 or x = -3
Step-by-step explanation:
1)
System of equations, we plug in y to the second equation
[tex]4x + 2(4x-7) = -2\\4x+8x-14 = -2\\12x = 12\\x=1[/tex]
We then plug x back into the first equation to find y
[tex]y = 4(1) -7\\y = -3[/tex]
2)
[tex]4x^2 +3=39\\4x^2=36\\x^2=9\\x=3, -3[/tex]

Find the length of the arc intercepted on the unit circle by the following central angle. 0=5π
A. 5π
B. 5/2π
C. 4π
D. 10π
well, since arc's length is s = rθ where θ is in radians, and in the Unit Circle r = 1 and we also know that θ = 5π radians, then
s = (1)(5π)
s = 5π.
pleas help with the khan academy question
Answer:
1. 10
2. 4
3. 8
Step-by-step explanation:
You have to fill in the given values for y and undo in reverse order to find x.
1. y = 6
6 = x - 4
6 (+ 4) = x - 4 (+ 4)
10 = x
2. y = 0
0 = x - 4
0 (+ 4 ) = x - 4 (+ 4)
4 = x
3. y = 4
4 = x - 4
4 (+ 4) = x - 4 (+ 4)
8 = x

Answer:
D. 102.6 in²
Step-by-step explanation:
The area of the square is 9 in² (3 × 3 = 9)
The area of the rectangle is 30 in² (3 × 10 = 30)
The area of the circle is 63.585 (a = πr², a = 3.14 × 4.5² - remember that the radius of a circle is half of the diameter)
Now, we can add these numbers together. 9 + 30 + 63.585 is 102.585 in² which is 102.6 in² rounded to 1 decimal place.
Hope this helps!
Answer:
Option D
Step-by-step explanation:
Square:
side = 3 in
[tex]\bf \boxed{\text{Area of square = side *side}}[/tex]
= 3*3
= 9 square inches
Rectangle:
length = 10 in
width = 3 in
[tex]\boxed{\text{Area of rectangle = length * width}}[/tex]
= 10 *3
= 30 inches
Circle:
diameter = 9 in
radius = 9 ÷ 2 = 4.5 in
[tex]\boxed{ \text{Area of circle = $\pi r^{2}$}}[/tex]
= 3.14 * 4.5 *4.5
= 63.6 square inches
Total area = area of square + area of rectangle + area of circle
= 9 + 30 + 63.6
= 102.6 square inches

PLEASE HELP!!! I WILL GIVE BRAINLIEST!!! AND NO LINKS PLEASE!!!!!
Answer:
To get the discount for the 5 pound bag of apples, we must first note the following:
The original price of the apples, which in this case it is 2.99
Also we must note the sale price for the apples which is 1.59
to get the discount for apples we must then create an equation based on the above information,
Discount for A= original price -sale price
Discount for A=2.99-1.59
Discount for A=1.40
Part 1 Answer is 1.40 which is the discount for apples at Handy Dandy Grocery.
Part 2
To get the discount for oranges we follow the same steps.
Discount for R= Original price for R -sale price for R
Discount for R=3.99-2.59
Discount for R=1.40
In conclusion, for both part one and part two we can derive a formula based on the apples and orange and say discount in both cases is arrived by the following:
D=Op-Sp. ( d= discount, Or= original price, Sp= sale price.)

The slope of a given line is. 3/5 What is the slope of the line parallel / perpendicular to
it? Write your answer as a fraction in simplest form.
Perpendicular lines have negative reciprocal slopes. That means the fraction is flipped and multiplied by negative 1. So if one line has a slope of 3/5, then a line perpendicular to it has a slope of -5/3.
A line perpendicular to another has a slope that is the negative reciprocal of the slope of the other line. The negative reciprocal of the original line is –2, and is thus the slope of its perpendicular line
A bag contains 7 marbles 3 red 2 blue 2 green what is the probability of picking a green marble. answer as a percent
Answer:
28.57%
Step-by-step explanation:
to find the probability of something being picked you divide the amount of what your trying to get (2) by the total amount of what's in it (7).
2÷7=.2857
to turn it into a percentage we move the decimal point 2 to the right
28.57
