A chorus teacher is arranging students on bleachers for a performance. The 1st row of the bleachers has 10 students, the 2nd row has 14 students, the 3rd row has 18
students, and the 4th row has 22 students.
Assuming the trend continues, how many students will be on the 6th row of the bleachers?
Assuming the trend continues, there will be 30 students on the 6th row of the bleachers.
According to the question,
We have the following details:
Number of students in 1st row = 10
Number of students in 2nd row = 14
Number of students in 3rd row = 18
Number of students in 4th row = 22
Now, if we carefully observe the arrangement made by the chorus teacher, we will observe that the arrangement has a pattern.
It is to be noted that with each row 4 students are increasing.
For example, in 2nd row the number of students is 14 (4 more than the previous row), in 3rd row the number of students is 18 (4 more than the previous row), etc.
Now, we have to find the number of students in 6th row. So, first we need to find the number of students in 5th row.
Number of students in 5th row = number of students in 4th row + 4
Number of students in 5th row = 22+4
Number of students in 5th row = 26
Now,
Number of students in 6th row = number of students in 5th row + 4
Number of students in 6th row = 26+4
Number of students in 6th row = 30
Hence, there are 30 students on the 6th row of the bleachers.

Answer:
1) Infinitely many solutions.
2) No real solutions.
3) (-1, 2)
Step-by-step explanation:
The solutions of a system of linear equations is whenever the two lines intersect.
However, if the two lines never intersect (they are parallel), then there are no solutions.
And if the two lines are the same line, then there are infinitely many solutions.
First Graph:
The two lines are exactly the same.
Hence, there are infinitely many solutions.
Second Graph:
The two lines are parallel. They will never intersect each other.
Therefore, there are no real solutions.
Third Graph:
The two lines intersect at the point (-1, 2).
Hence, there is only one solution and it is (-1, 2).

Answer:
A) x=8 and angle ABC=115 degrees
Step-by-step explanation:
the lines are parallel, meaning the angles are congruent.
you can set up the equation (15x-5)=(10x+35) and simplify.
1. separate variable by subtracting 10x on both sides to get (5x-5)=(35)
2. add 5 on both sides to get 5x=40
3. divide both sides by 5 to get x=8
4. plug x=8 into original function (10x+35) to get (10(8)+35) which equals 115 degrees

A golfer hit a ball 230 m from the tee to the
green. The ball traveled south and landed on the
green in 4 seconds. What was the ball's speed?
Answer:
The ball's speed is 57.5 m/s
Step-by-step explanation:
Given;
distance between the tee and the green, d = 230 m
time taken for the ball to travel from the tee to the green, t = 4 seconds
The speed of the ball is given as;
speed = total distance traveled / total time taken
speed = 230 m / 4 s
speed = 57.5 m/s
Therefore, the ball's speed is 57.5 m/s

Use the Pythagorean theorem:
70^2 = 42^2 + width^2
4900 = 1764 + width ^2
Subtract 1764 from both sides
3136 = width^2
Take the square root of both sides
Width = 56 inches

Step-by-step explanation:
How many gallons of pure water should be evaporated from 160 gallons of a solution containing 12% salt
so that the remaining solution contains 20% salt?
What are you being asked to find in this problem?
O gallons of pure water
gallons of 12% salt solution
gallons of 20% salt solution
what is the original amount of solution in gallons? a=
Answer:
66 gallons
Step-by-step explanation:
Given that initially 160 gallons of a solution containing 12% salt.
So, the initial amount of salt = 12% of 160 = 12/100 x 160 = 19.2 gallons.
Let x gallons of water get evaporated so that the remaining solution contains 20% salt.
The remaining amount of solution = 160-x gallons.
As the initial amount of salt is still in the solution which is equal to 20% of the remaining solution, so
19.2 = 20% of (160-x)
[tex]\Rightarrow 19.2 = \frac {20}{100}\times (160-x) \\\\\Rightarrow 19.2 = \frac {1}{5}\times (160-x) \\\\\Rightarrow 19.2 \times 5= 160-x \\\\\Rightarrow 96= 160-x \\\\\Rightarrow x= 160-96 \\\\[/tex]
[tex]\Rightarrow x= 66[/tex] gallons
Hence, 66 gallons of water must be evaporated to get a 20% salt solution.

its A, "gallons of pure water"

Find the value of c that makes x^2+20x+c a perfect square trinomial. And then write expression as the square of a binomial.
The value of the variable 'c' is 10. Then the perfect square trinomial is (x + 10)².
What is a perfect square trinomial?A perfect square trinomial formulation can be created by taking the binomial equation's squared. If and then only if a trinomial satisfying the criterion b² = 4ac has the form ax² + bx + c, it is indeed a perfect square.
The trinomial is given below.
⇒ x² + 20x + c
The value of 'c' must be equal to half of the square of the coefficient of x. Then we have
c = [1/2 × (20)]²
c = (10)²
c = 100
Then the perfect square trinomial is written as,
x² + 20x + 100 = (x + 10)²
The value of the variable 'c' is 10. Then the perfect square trinomial is (x + 10)².

Answer: A real life example would be if you would add 100 dollars in a bank account and then, subtract the 100 dollars from that account.
The equation used would be 100 + (-100) or in a simpler version 100 - 100 (They both mean the same thing!)

Wow that's hard to look at. But, when zooming in, we can see that the arrow is closer to 116 degrees, so that is the answer.
Step-by-step explanation:
Notice that the angle/arrows is opening up from right to left, so it will be greater than 90 degrees. The arrow is a little bit more than 115 degrees, so it has to be 116 degrees.
