Answer:
213,645.6cm³
Step-by-step explanation:
Area of a cylinder is expressed as;
V = πr²h
r is the radius = 2cm
h is the height = 70cm
Get the volume of one rod;
V = πr²h
V = (3.14)(2)²(70)
V = (3.14)(4)(70)
V = 879.2cm³
one steel = 879.2cm³
243 rods = x
Cross multiply;
x = 879.2 * 243
x = 213,645.6
The company will need 213,645.6cm³ volume of steel to make 243 rods

The price of a computer component is decreasing at a rate of 10% per year. State whether this decrease is linear or exponential. If the component costs $ 110 today, what will it cost in three years?
Answer:
The cost in 3 years is $80.19.
Step-by-step explanation:
The cost of computer component is $110 today.
The cost is decreasing at a rate of 10% per year.
When it decreases by 10% per year then it is exponential.
Initial cost is $110. When it decreases 10% per year, the decay factor is 1-0.10 =0.90.
So, we could use the exponential formula y=[tex]ab^{x}[/tex]
Where 'a' is initial cost and b is decay factor.
Our equation would by plug in 'a' as 110 and 'b' as 0.90.
We get
[tex]y= 110(0.9)^{x}[/tex]
Now, to find the cost in 3 years, use x as 3.
[tex]y=110(0.9)^{3}[/tex]
Which is simplified to
y=$80.19

Is the point (10,-2) a solution to the equation y = -2x + 16? Explain,
??? pls answer
Answer:
no
Step-by-step explanation:
y = -2x + 16
-2 = -2(10) + 16
-2 = -20 + 16
-2 = -4
which is wrong
Plug the point (10,-2) into y = -2x + 16 and solve. If the equation is a true, then yes, it is a point on the equation.
y = -2x + 16 > -2 = -2(10) + 16
Now, solve.
-2 = -2(10) + 16 > -2 = -20 + 16 - Start by multiplying out parenthesis.
-2 = -20 + 16 > -2 = -4 - Add.
-2 = -4
The equation cannot be simplified any further. Since -2 is not equal to -4, we can conclude that no, (10,-2) is not a solution to the equation y = -2x + 16.

Ally has 8 red marbles and 16 green marbles. She also has red bags and green bags. She wants to put marbles in the bags that match their color. Each bag will have the same number of marbles. What is the largest number of marbles she can put into each bag?
Answer:
The largest number of marbles she can put into each bag is 8 marbles.
Step-by-step explanation:
We solve the question above using Greatest common factor method
We find the factors of 8 and 16 and the Greatest number common to both factor is our answer.
Hence:
The factors of 8 are: 1, 2, 4, 8
The factors of 16 are: 1, 2, 4, 8, 16
Then the greatest common factor is 8.
Therefore, the largest number of marbles she can put into each bag is 8 marbles.
