Answer:
The formula to find the surface area of a sphere is to take the radius of the sphere and square it and multiply that amount by pi and then multiply that by 4. This is written algebraically as S=4πr2, where S is the surface area, r is the radius, and the value of π is 3.14.
What is the equation of the line
Answer:
y=-6/7x-3
Step-by-step explanation:
On a graph, I plotted (7,-9) and the used the slope given but it was very off. On the slope -6/7x one of the plots is (7,-6). From the two lines, just go down 3 times and you would reach your plot again. What I mean is, do -6- 3=-9 so the answer is '- 6/7x-3. I used demos graphing calculator & calculator to make sure that my answer was 100% correct. You can use it too if you don't wan to use graph paper.
Hope this helps and comment or send a private message if you need help.

2x+y=5
2x-y+=5
x+2y=5
Answer:
[tex]2x + y = 5 \\ y = 5 - 2x[/tex]
[tex]2x - y + = 5 \\ - y = 5 - 2x[/tex]

c. Write an expression to represent the length of a string in yards in terms of the string's length, x, in inches
Answer:
Answer:
y = \frac{x}{36}y=
36
x
Step-by-step explanation:
Given
Length of string = x inches
Required
Determine the length in yards
Represent the equivalent length with y
Such that
y = x\ inchesy=x inches
Divide x by 36 to get equivalent in yards
y = \frac{1}{36} * xy=

∗x
y = \frac{x}{36}y=

Hence, the equivalent in yards is \frac{x}{36}

Solve the system. Explain your choice of solution method.
5x - 2y = 2
2x - y = - 46
Explain your choice of solution method.
O A. The substitution method is the best choice because one of the equations is already solved for the variable.
OB. The substitution method is the best choice because one of the variables in one equation has a coefficient of 1
O C. The elimination method is the best choice because the coefficient of x in the second equation is a multiple of the coefficient of x in the first equation
OD. The substitution method is the best choice because both of the equations are already solved for constants
O E. The elimination method is the best choice because the coefficient of y in the second equation is a multiple of the coefficient of y in the first equation
9514 1404 393
Answer:
B. The substitution method is the best choice because one of the variables in one equation has a coefficient of 1
Step-by-step explanation:
We find the easiest choice to be using a graphing calculator (see attached). It shows the solution to be (x, y) = (94, 234).
__
The only coefficient with a magnitude of 1 is the coefficient of y in the second equation. That coefficient is -1, not 1. The only coefficients related by an integer are the coefficients of y: the coefficient of y in the first equation is a multiple of that in the second equation.
Strictly speaking, none of the answer choices matches the reasoning.
__
We could use substitution, because the coefficient of y in the second equation is -1.
y = 2x+46
5x -2(2x +46) = 2
x = 2+92 = 94
y = 2(94) +46 = 234
The solution by substitution is (x, y) = (94, 234).
__
We could use elimination, because the coefficient of y in the first equation is a multiple of the coefficient of y in the second equation.
(5x -2y) -2(2x -y) = (2) -2(-46)
x = 94 . . . . . . simplified
2(94) -y = -46 . . . . substitute into the second equation
y = 2(94) +46 = 234
The solution by elimination is (x, y) = (94, 234).
_____
Additional comment
Here, I like the substitution best, because once we solve for y, we can use that with our solution for x. It seems like less work than using the elimination method, though both solutions are shown here in 4 lines.

Step-by-step explanation:
A city planner designs a park that is a quadrilateral with vertices at J(-1, 1), K (3, 3), L (5, -1), and
M(-1,-1). There is an entrance to the park at the midpoint of each side of the park. A straight path
connects each entrance to the entrance on the opposite side. Assuming each unit of the coordinate plane
represents 10 meters, what is the total length of the paths to the nearest meter? Round your answer to
the nearest whole number.
The total length of the paths is approximately
meters.
9514 1404 393
Answer:
83 m
Step-by-step explanation:
The attached diagram shows the lengths of the midlines to be 3.16 and 5.10 units on the coordinate plane. The sum of these is (3.16 +5.10) = 8.26 coordinate plane units. Since each unit on the coordinate plane represents 10 m, the total path length is about ...
8.26(10 m) = 82.6 m ≈ 83 m
_____
The distance formula will tell you the distances are ...
AC = √(3² +1²) = √10
BD = √(5² +1²) = √26
The total path length is about (10 m)(√10 +√26) ≈ 82.61230 m ≈ 83 m.
Express (16^3)^1/2
in simplest radical form.
Answer:
I assume you mean 16^(1/3) i.e. the cube root of 16
I am also assuming you mean the real cube root because, as you may know, every non-zero real number has three cube root - one real and two complex conjugates.
Since 16 = 8 x 2 and 8 = 2³ then (2³ x 2)^1/3 = (2³)^1/3 x 2^1/3 = 2 x 2^1/3
You might check that the cube root of 16 is about 2.52 which is twice the cube root of 2
