Answer:
Step-by-step explanation:
k = xy
Putting values of x and y in the equation
k = (5)(-3.5)
= - 17.5
Finding value of x when y = 10
k = xy
- 17.5 = x10
Bringing like terms on one side
- 17.5 - 10 = x
-27.5 = x

A college has thirteen instructors qualified to teach a special computer laboratory course which requires two instructors to be present. How many different pairs of instructors could there be?
Answer:
156 different pairs will be there.
Step-by-step explanation:
As the order is essential as we need different pairs therefore permutations will be used.
A permutation is any ordered subset of the objects r selected with regard to their order, from the set of n distinct objects. It is given by nPr where n> r
Total number is 13 and required number is 2
n= 13 and r= 2
13 P2= 156 possible combinations.
A combination is any subset of the objects r selected without regard to their order, from the set of n distinct objects. It is given by nCr where n> r
A sphere has a volume of V = 1764 in. Find its surface area.
Answer:
The surface area is 706.02
Step-by-step explanation:
SA = 224.4pi (704.62)
Alternatively (706.02 without rounding)
First, we need to find the radius of the sphere with the following equation
[tex]r = (3\frac{V}{4\pi } )^\frac{1}{3} \\r = (3\frac{1764}{12.56} )^\frac{1}{3} \\r = (3*140.45)^\frac{1}{3} \\r = (421.35)^\frac{1}{3} \\r = 7.49[/tex](pi as 3.14)
Now we can find the surface area using the following equation
[tex]SA = 4r^2\pi \\SA = 4(56.1)\pi \\SA = 224.4\pi \\[/tex]
Marco picked answer A for the following problem. Why is that not the correct answer? (NO LINKS)
Answer:
This is not correct because the organic rice line in Graph A is increasing more than the conventional rice line. This is why the x- and y-labels are important: organic rice in Graph A; you are able to get more pounds for the same amount of weight. If organic rice costs more, you should get less pounds of rice. Graph B shows this relationship because the conventional rice line is higher than the orangic rice line, which indicates that you can get more conventional rice than organic rice at the same price, which is what the question says.
HELP PLEASE. find the volume of the figure. (3.14 as pi)
Answer:
The volume of the figure is 720 cm^3
Step-by-step explanation:
Here, we want to find the volume of the figure
mathematically, we can have this as the product of the base of the figure and it’s height
the base is a rectangle and the area is the product of the side lengths
Mathematically, we have this as;
9 * 20 = 180 cm^2
So the volume here can be obtained by simply multiplying by the height of the shape
we have this as;
180 cm^2 * 4 cm = 720 cm^3

Which statement describes values of x and y such that could be an irrational number?
A. The value of x is zero, and the value of y is an integer less than zero.
B. The value of x Is the square root of an integer, and the value of y is an Integer
greater than zero.
C. The value of x Is an Integer less than zero, and the value of y is an Integer greater than zero.
D. The value of x Is a square root that can be simplified to an Integer, and the value of y is an
Integer less than zero.
The answer is B
It's not A, C, or D, because they all are stated as integers, which cannot be irrational

Answer:
68 games
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Games won = 85%
Game lost = 12
Here, 100% - 85% = 12
15% = 12
or 1% = 0.8
So, total games played (100%) = 80 games
Now, number of games won = Total games - Games lost
= 80 - 12
= 68 games
Hence, Kelly's team wins 68 games in the season.

What is the volume of the pyramid? 2.4 cm3 3.6 cm3 4.8 cm3 7.2 cm3
Answer:
C 4.8cm^3
Step-by-step explanation:
The volume of the pyramid is 4.8 cm³.
Given that a pyramid with base side length is 2 cm, we need to find the volume of the pyramid,
Volume of a pyramid = 1/3 × base area × height
So,
We have ∠ABC = 45°, in right triangle ΔACB,
Since ∠ABC = 45° therefore, ∠BAC = 45°,
So, AC = BC = 3.6 cm,
So, the volume = 1/3 × 2² × 3.6
= 4 × 1.2
= 4.8
Hence the volume of the pyramid is 4.8 cm³.

Choose an equivalent system of equations to the following system:
Fx + Gy = H
Qx + Ry = S
6Fx + Gy = 6H
Qx + 6Ry = S
6Fx + 6Gy = 6H
Qx + Ry = S
Fx + 6Gy = 6H
Qx + Ry = S
6Fx + 6Gy = 6H
Qx − Ry = S
Answer:
B. 6Fx + 6Gy = 6H
Qx + Ry = S
Step-by-step explanation:
Equivalent equations can be created many ways. One of the simplest is to multiply both sides of the equation by the same number. In the answer above, the first equation has been multiplied by 6. Nothing has been done to the second equation.
_____
Comments on other choices
A: some terms have been multiplied by 6. This changes the equation(s) so they are no longer equivalent to the ones you started with.
B: the correct choice
C: see A.
D: the first equation has been multiplied by 6, so that is equivalent to the original. The second equation has the sign of one of the terms changed, so it is now a different equation.
Answer:
6Fx + 6Gy = 6H
Qx + Ry = S

Netflix charges David $15 per month for a membership, plus a one time $5 fee to stream on his phone. How many months will David have his membership if Netflix charges David $50?
Answer:
David will have his membership for 3 months.
Step-by-step explanation:
For the first month + the one-time mobile fee, that is $15 for one month + $5 for the fee.
So far, he has been charged $20.
Another month's cost is $15 more, which will bring his total cost to $35.
Another month's cost is $15 more, which will bring his total cost to $50.
If Netflix charges David $50, that means he will have paid the mobile fee, and have had his membership for 3 months.
