3 cube is 27
27 minus 6.8 is 20. 2
20. 2 decide by 7 is 2.89
Answer:
the answer would be 3
Step-by-step explanation:
Because 3 to the third power is 27 and 6 times 8 is 48 so you subtract 27 and 48 and you get 21 so you divided 21 and 7 and you get 3. sorry if that's confusing but I hope it helped.

What type of correlation relationship would the size of a dog and the amount of food the dog eats be and why?
Step-by-step explanation:
The ratio and proportion is the mathematical concept that can explain the correlation between the size of a dog and the amount of food it eats. For example dogs weighing 3 to 7 kg should consume 67 to 112 grams of food per day, that is, the amount of food must be proportional to the weight of the dog.
The ratio and proportion are interconnected concepts that allow the understanding of comparison between quantities.

2x + y = 20
6x – 5 y= 12
Answer:
hi
Step-by-step explanation:
We see a set of linear equations. Hence, a system of linear equations. So we solve them by process of elimination, multiplying the top equation by 5 to eliminate first such that
(2x+y=20)*5
6x-5y=12
-----------------------------------------
10x+5y=100
6x-5y=12
--------------------------------
16x = 112 .............After dividing 16 we get
x = 7
Now we plug x = 7 back into the original first equation to obtain the y value such that
2(7) + y = 20
12 + y = 20
-12 -12
------------------
y = 8
I hope this helped!

Which statement about this table of values is true?
A.Because the rate of change is constant, the function is linear
B.Because the rate of change is constant, the function is nonlinear
C.Because the rate of change is not constant, the function is linear
D.Because the rate of change is not constant the function is nonlinear
Answer:
D
Step-by-step explanation:
If something is not constant we know it is non-linear. We know this is not constant because when graphed, the line is not straight.
Answer:
D.
Step-by-step explanation:
Here the rate of change is not constant. For example:
10-5 / 20-17 = 5/3
13-10/23-20 = 3/3 = 1
A hollow metallic cylinder is made from a metallic sheet of 2.4 cm thickness. The inner
radius of the cylinder is 5.8 cm and the length is 50 cm. Find the volume of the metal used.
step by step explain plz
Answer:
The volume of the metal used is 5277.9 cm³.
Step-by-step explanation:
The volume of a cylinder is given by:
[tex] V = \pi r^{2} h [/tex]
Where:
r: is the radius
h: is the height = 50 cm
The volume of metal ([tex]V_{m}[/tex]) can be found by subtracting the internal volume ([tex]V_{i}[/tex]) from the external volume ([tex]V_{e}[/tex]):
[tex] V_{m} = V_{e} - V_{i} [/tex]
[tex] V_{m} = \pi r_{e}^{2} h - \pi r_{i}^{2} h [/tex]
The external radius is given by the sum of the internal radius with the tickness:
[tex] r_{e} = t + r_{i} [/tex]
Hence, the volume is:
[tex] V_{m} = \pi*50 cm((2.4 cm + 5.8 cm)^{2} - (5.8 cm)^{2}) = 5277.9 cm^{3} [/tex]
Therefore, the volume of the metal used is 5277.9 cm³.
I hope it helps you!
Moussa's family took a road trip to the Grand Canyon. Moussa fell asleep after they
had travelled 434 miles. If the total length of the trip was 700 miles, what percentage
of the total trip had they travelled when Moussa fell asleep?
Answer:
38%
Step-by-step explanation:
So first you need to find what 434/700 is because that is when she fell asleep. Divide each side by 2 to get 217/350. Use division to find the decimal. Once you are done with that, you get 0.62. You then subtract 0.62 from 1 because that is the amount of when she fell asleep. 1-0.62=0.38. 0.38 is also 38% so Moussa fell asleep for 38% of the trip.
Hopefully this helps you

factor of 9x2 18x + 8?
Factor of 9x^2-18x+8
Answer:
(3x - 2)(3x - 4).
Step-by-step explanation:
9x^2-18x+8
Use the 'ac' method:
9 * 8 = 72.
We need 2 numbers whose product is + 72 and whose sum is -18
These are -12 and -6 so we rewrite the expression as:
9x^2 - 12x - 6x + 8 Now we factor by grouping:
= 3x(3x - 4) - 2(3x - 4) The 3x - 4 is common so we have:
(3x - 2)(3x - 4).
The factor of the quadratic expression 9x² - 18x + 8 will be (3x - 2) and (3x - 2).
What is factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The quadratic expression is given below.
⇒ 9x² - 18x + 8
Factorize the quadratic expression, then the factors are given as,
⇒ 9x² - 18x + 8
⇒ 9x² - (12 + 6)x + 8
⇒ 9x² - 12x - 6x + 8
⇒ 3x(3x - 4) -2(3x - 4)
⇒ (3x - 2)(3x - 4)
Then the factor of the quadratic expression 9x² - 18x + 8 will be (3x - 2) and (3x - 2).
