[tex]\boldsymbol{4}[/tex] is closest to the radius, in inches, of the cylinder.
So, option A. is correct.
Volume of cylinderHeight of a cylinder [tex](h)=8[/tex] inches
Volume of a cylinder[tex]=400[/tex] cubic inches
Let [tex]r[/tex] denotes radius of a cylinder.
Volume of a cylinder [tex]=\pi r^2 h[/tex]
[tex]400=\frac{22}{7}r^2 (8)[/tex]
[tex]r^2=15.9\\r=3.99[/tex]
So, [tex]\boldsymbol{4}[/tex] is closest to the radius, in inches, of the cylinder.
So, option A. is correct.

2x1+0x2+3x3=3
4x1-3x2+7x3=5
8x1-9x2+15x3=10
solve the system using Gaussian or Gauss-Jordan elimination
[1] … … 2x₁ + 0x₂ + 3x₃ = 3
[2] … … 4x₁ - 3x₂ + 7x₃ = 5
[3] … … 8x₁ - 9x₂ + 15x₃ = 10
Since [1] is already free of x₂, you might as well start by eliminating x₂ from the other two equations. Add -3 times [2] to [3] :
-3 (4x₁ - 3x₂ + 7x₃) + (8x₁ - 9x₂ + 15x₃) = -3 (5) + 10
-12x₁ + 9x₂ - 21x₃ + 8x₁ - 9x₂ + 15x₃ = -15 + 10
-4x₁ - 6x₃ = -5
[4] … … 4x₁ + 6x₃ = 5
Now eliminate x₃ in [1] and [4]. Add -2 times [1] to [4] :
-2 (2x₁ + 3x₃) + (4x₁ + 6x₃) = -2 (3) + 5
-4x₁ - 6x₃ + 4x₁ + 6x₃ = -6 + 5
0 = -1
which is a contradiction. This means the system has no solution.

Step-by-step explanation:
10+3y-2=4y-y+8
10+3y-2 combine 10 and -2 and you get 3y+8
4y-y+8 combine the 4y with the -y and you get 3y+8

Answer:
false
Step-by-step explanation:
use bidmas :)
ok, let's rewrite this for b = 5
65 ÷ 5 + 8 × 4 = 20
now put brackets
(65 ÷ 5) + (8 × 4) = 20
(13) + (32) = 20
13 + 32 = 45

Step-by-step explanation:
Ten field hockey teams are competing in a tournament. Only the top three teams will be recognized as the first place, second place and third place winners. In how many ways could the ranking of the top three teams occur?
Answer:
The ranking of the top three teams could occur in 720 ways.
Step-by-step explanation:
The order in which the teams are ranked is important, that is, for example, Oilers, Flames and Canucks is a different outcome of Oilers, Canucks and Flames. This means that the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In how many ways could the ranking of the top three teams occur?
Three teams from a set of 10. So
[tex]T = P_{(10,3)} = \frac{10!}{7!} = 720[/tex]
The ranking of the top three teams could occur in 720 ways.

Answer:
Solution given:
we have
m<PTQ=m<RTS
x+20=3x+12.
20-12=3x-x
x=
[tex] \frac{8}{2} [/tex]
now
16.m<PTQ=x+20=4+20=24°
17.
again
m<PTR+m<PTQ=180°[supplementary]
so
m<PTR=180°-24°=156° is your answer
Answer:
156°
Step-by-step explanation:
I see you have already found the x so now plug it in.
(4)+20=24
(4)(3)+12= 24
Since they are vertical angles, then they are congruent, thats why they are equal. By now I think you should know that a straight line is equal to 180, so lets take 1 angle to find the missing one.
We can also see that ∠PTR and ∠RTS are also vertical angles, so they are also congruent. So we only use one, 180-24=156
the answer is 156 because ∠PTR and ∠PTQ are in the same line making them supplementary.

Answer:

Step-by-step explanation:
A nonlinear function Group of answer choices is a function with a slope that is not constant. is a concept that only applies to the case of a single or two explanatory variables since you cannot draw a line in four dimensions. makes little sense, because variables in the real world are related linearly. can be adequately described by a straight line between the dependent variable and one of the explanatory variables.
Answer:
is a function with a slope that is not constant.
Step-by-step explanation:
A linear function has a positive relationship and as such an increase in one variable (input variable) causes an increase in the other variable (output variable) i.e the variables are directly proportional. Thus, the graph of a linear function is a straight-line and its slope is always constant.
On the other hand, nonlinear function has a negative relationship and as such an increase in one variable (input variable) causes a decrease in the other variable (output variable) i.e the variables are inversely proportional.
This ultimately implies that, the graph of a nonlinear is a curved line and whose direction is constantly changing.
Hence, a nonlinear function is a function with a slope that is not constant. An example of a nonlinear function is a quadratic function or equation.

In the following diagram, a quarter circle has been constructed using an isosceles right triangle whose legs measure 8 inches. Which of the following represents the area of the shaded region, rounded to the nearest tenth of a square inch?
Answer:
Area of Shaded Area = 18.3
Step-by-step explanation:
P.S - The exact question is -
Given - In the following diagram, a quarter circle has been constructed using an isosceles right triangle whose legs measure 8 inches.
To find - Which of the following represents the area of the shaded region, rounded to the nearest tenth of a square inch?
Proof -
We know that,
Area of a quarter circle = [tex]\frac{1}{4} \pi r^{2}[/tex]
Also,
We know that ,
Area of isosceles Triangle = [tex]\frac{1}{2}*Base*Height[/tex]
Now,
Given that,
Radius of quarter circle = 8 inches
Base of Isosceles Triangle = 8 inches
Height of Isosceles Triangle = 8 inches
∴ we get
Area of a quarter circle = [tex]\frac{1}{4} \pi (8)^{2}[/tex] = 16[tex]\pi[/tex]
Area of isosceles Triangle = [tex]\frac{1}{2}*8*8[/tex] = 32
Now,
Area of Shaded area = Area of a quarter circle - Area of isosceles Triangle
= 16[tex]\pi[/tex] - 32
= 50.265 - 32
= 18.265 ≈ 18.3
⇒Area of Shaded Area = 18.3
A store is giving out cards labeled 1 through 10 when customers enter the store. If the card is an even number, you get a % discount on your purchase that day. If the card is an odd number greater than 6, you get a % discount. Otherwise, you get a % discount. The table shows the results of customers. What is the relative frequency for each discount? Use pencil and paper. If the manager of the store wants approximately half of the customers to receive the % discount, does this seem like an appropriate method? Explain.
