A company makes steel rods shaped like cylinders. Each rod has a radius of 2 centimeters and height of 70 centimeters. How much steel will the company need to make 243 rods? Use 3.14 for pie, and round your answer to one decimal
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

Point M is located in Quadrant II of the coordinate plane. Point J has the same x-coordinate and the opposite y-coordinate as Point M. Point K has the opposite x-coordinate and the opposite y-coordinate as Point M Part A In what quadrant is Point J located Part B In what quadrant is Point K located?
Answer:
The answer is below
Step-by-step explanation:
The x-axis (horizontal axis) and y axis (vertical axis) divide the coordinate plane into four section known as quadrant.
In the first quadrant, the x and y coordinate are positive, in the second quadrant, the x coordinate is negative and y coordinate is positive. In the third quadrant, the x and y coordinate are negative while in the fourth quadrant, the x coordinate is positive and y coordinate is negative.
Point M is in Quadrant II, hence M = (-x, y).
Point J has the same x-coordinate and the opposite y-coordinate as Point M, hence J = (-x, -y).
Point K has the opposite x-coordinate and the opposite y-coordinate as Point M, hence K = (x, y).
A) Since J = (-x, -y), point J is in the third quadrant.
B) Since K = (x, y), point K is in the first quadrant

Chris paid $36 for 3 tanktops and 2 shirts. a shirt cost 3 times as much as a tank top. how much did chris pay for the 2 shirts?
Answer:
$72
Step-by-step explanation:
36/3=12
1 tanktop=$12
12*3=36
1 shirt equals=$36
36*2=72
2 shirts=$72
a = 6x-11
g= 36
n = 7x - 27
Solve for x
Answer:
6x - 11 + 7x - 27 = 36
6x + 7x = 13x
-11 + (-27) = -38
13x - 38 = 36
-38 - 36 = -74
13x/13 = -74/13
x = -74/13
Step-by-step explanation:
can no longer be simplified

The graph of a system of two linear equations is shown. How many solution does the system of equation have?
A. No Solution
B. Infinitley Many Solutions
C. Two Solutions
D. One Solution
Answer:
two solutions
Step-by-step explanation: it cant be no solution because no solution will be a vertical line it can be one solution becuase y=x is a solution and so is y=4
i am confused on how to solve this
Answer:
a) Both slopes are 4
b) The function g(x) has a greater y-intercept
Step-by-step explanation:
a) To find the slope of the function g(x), simply look at the coefficient (the number before the variable x). In this case, the coefficient is 4, so your slope is 4. This is because the equation is in slope-intercept form: y = mx + b where m is the slope.
To find the slope of function f(x), take two y-coordinates (y-coordinates are found in the column f(x)) and subtract one from another. This is your rise. Then, take two x-coordinates (from column x) and subtract one from another. This is your run. Divide the rise by the run, and you have your slope. In this case, you should get 4/1, or 4.
b) To find the y-intercept for function g(x), take a look at slope-intercept form again: y = mx + b, where b represents the y-intercept. So, the "b" of g(x) = 4x + 3 is 3. Your y-intercept is 3.
To find the y-intercept of function f(x), locate the row where there is a zero under column x. In this case, it's the second row. The number -1 is your y-coordinate when x is zero. Your y-intercept is -1.
-1 is less than 3, so the y-intercept of function g(x) is greater.
Hope this helps!
In a group of 250 music lovers, 135 of them like folk songs and 150 like modem
songs. By drawing a Venn-diagram, find;
(i) how many people like both the songs?
(ii) How many people like only one song?
Please help me i will mark brainlist
Answer:
i cant make a diagram but here i go.
Step-by-step explanation:
250-135=115
250-150=100
100+115=215
250-215=35
So your answer is that 45 people like both, 115like modern, 100 like folk song, and 35 like both.
The points (-1, 5) and (7, r) lie on a line with slope 5/4
Find the missing coordinate r.
Answer:
15
Step-by-step explanation:
7-(-1) is 8
8 divided by 4 (x or “run” of slope) is two
Two times five (y/rise of slope) is ten
5 (from original point -1,5) plus 10 is 15
(7,15)

Alfredo is buying a watch for $200. He will make an initial payment of $50 and
then pay the remaining balance in payments of $15 per week.
Which function can be used to find a, the amount he will still need to pay at the
end of n weeks?
Answer:
Step-by-step explanation:
There is nothing to choose from.
However, 200-50 down payment will leave 150 left on the watch. 150 divided 15 a month is 10 months.
200=50+15(n)
200=50+15(10)
