Answer:
seats are in row 12 is 136
seats are in row 136 is 880
seats are in the auditorium is 1071000
Step-by-step explanation:
given data
rows of seat = 51
first row seats = 70
each row seats = 6
to find out
How many seats are in row 12 ,136 and How many seats are in the auditorium
solution
it is AP as 70 , 76 , 82, 88 ............
here A = 70 , d = 6
for n = 12 and 136
so An = a + (n-1)d .........1
A(12) = 70 + (12-1)6
A(12) = 136
and
A(136) = 70 + (136-1)6
A(136) = 880
and
for total seat we get here Sn for 51 row
Sn = [tex]\frac{n}{2}[/tex] × [ 2a(n-1)d] ...........2
put here value
Sn = [tex]\frac{51}{2}[/tex] × [ 2(70)(51-1)6]
Sn = 1071000

Answer:
A. 9(x + 8) = 9(x + 12)
Step-by-step explanation:
Simplify the probelm;
9(x + 8) = 9(x + 12)
Distribute;
9x + 72 = 9x + 108
Inverse opreations;
9x + 72 = 9x + 108

A ball is thrown from an intial height of 5 feet with an intial upward velocity of 17 ft/s. The ball's height h in feet after t seconds is given by the following.
h=5+17t-16t^2
Find all values of t for which the ball's height is 9 feet.
Round your answer(s) to the nearest hundredth.
Answer:
-16t²+17t+7=11
==>16t²-17t+4=0
Δ=17²-4*4*16=33

Option D: 5√5 is the correct answer.
Step-by-step explanation:
Given that:
√20 + √45
These can also be written in simplified form;
√5*4 + √5*9
We will take square root of 4 and 9.
The square root of 4 and 9 is,
√4 = 2
√9 = 3
Thus,
2√5 + 3√5
Adding the roots,

Jennifer had some money in her pocket. She spent $1.35, which left her with $2.30. Write an equation or an inequality to find the original amount of money she had in her pocket.
Answer:
Equation: X-1.35= 2.30
Value of X: x=3.65
Step-by-step explanation:
You can choose whatever variable you want to represent the original amount of money Jennifer had in her pocket. I decided to use X as my variable.
If X represents the original amount of money Jennifer had in her pocket, then I can write this equation:
X-1.35= 2.30
Essential what this equation shows is that Jennifer spends $1.35 of what she originally has, which is x. After she spends that she's left with $2.30. This is how we solve for x, also known as the original amount Jennifer had in her pocket:
X-1.35= 2.30
(we will add 1.35 to each side because we what to balance out the equation and the inverse operation of subtraction is addition)
X= 3.65
So Jennifer originally had $3.65 in her pocket before she spent the $1.35
( Hope this helps :). Let me know if there's any confusion in my answer/explanation)

The problem
Answer:
3/2 or 1.5
Step-by-step explanation:
We need the denominator to be the same so we multiply 6/7 by 2/2 to get 12/14. Now we add 12/14+9/14 which is 21/14. We can simplify 21/14 to 3/2, or 1/5 in decimal form. If you need it in mixed number form, it is 1 1/2

Step-by-step explanation:
A random sample of 27 fields of rye has a mean yield of 43.1 bushels per acre and standard deviation of 5.31 bushels per acre. Determine the 80% confidence interval for the true mean yield. Assume the population is approximately normal. Step 2 of 2 : Construct the 80% confidence interval. Round your answer to one decimal place.
Answer:
The 80% confidence interval = (41.8, 44.4)
Step-by-step explanation:
From the above question, the random number of samples is 27, this sample size is below 30, hence it is small.
To solve for this, we have use t score instead of confidence interval.
Degrees of freedom = 27 - 1 = 26
t score for 80% confidence interval = 1.315
The 80% confidence interval = Mean ± t score × standard deviation/√n
Mean = 43.1 bushels
Standard deviation = 5.31
Hence,
43.1 ± 1.315 × 5.31/√27
43.1 ± 1.3438116191
Hence:
43.1 - 1.3438116191
= 41.756188381
≈ 41.8
43.1 + 1.3438116191
= 44.443811619
Approximately ≈ 44.4
Therefore, the 80% confidence interval = (41.8, 44.4)
What is the value of z?
Answer:
68°
Step-by-step explanation:
Every figure must sum 180°(Sides-2) degrees
Example: For a triangle (3 sides) 180°(3-2) => 180°(1) =>180°
In this case: 5 sides 180°(5-2) => 540°
So all the angles (5) must sum 540°
Mathematically expressed as:
[tex](119)+(z)+(2z)+(70)+(2z)+(11)=540\\119+z+2z+70+2z+11=540\\200+5z=540\\5z=540-200\\5z=340\\z=\frac{340}{5}\\z=68'[/tex]
Lets see changing every Z by 68...
119+68+2(68)+70+2(68)+11
119+68+136+70+136+11=540°

Suppose you start at the origin, move along the x-axis a distance of 4 units in the positive direction, and then move downward along the z-axis a distance of 2 units. What are the coordinates of your position
Answer:
[tex]B = (x+4,y-2)[/tex]
Step-by-step explanation:
Let the current position be A:
[tex]A = (x,y)[/tex]
Required
Determine the new position
First, you move 4 units to the right.
This is represented as [tex]x + a[/tex]
Where a is the number of units to the right
In this case:
[tex]a = 4[/tex]
So, we have: [tex]x + 4[/tex]
Then you move 2 units downwards
This is represented as [tex]y - b[/tex]
Where b is the number of units downwards.
In this case:
[tex]b = 2[/tex]
So, we have: [tex]y - 2[/tex]
So, the new position (B) is:
[tex]B = (x+4,y-2)[/tex]

4.8 + 2.2w − 1.4w + 2.4
Answer:
7.2 + 0.8w
Step-by-step explanation:
combine like terms. Like terms have same variable with same power.
2.2w and (-1.4w) are like terms & 4.8 and 2.4 are like terms.
4.8 + 2.2w - 1.4w + 2.4 = 4.8 + 2.4 + 2.2w - 1.4w
= 7.2 + 0.8w
Answer:
7.2+0.8w
Step-by-step explanation:
4.8+2.2w-1.4w+2.4
4.8+2.4=7.2 2.2w-1.4w=0.8w
Xavier start 5 feet away from the motion detector. He then walks away from the detector at a rate of 0.5 ft./s for four seconds. He remains still for two seconds, and then walks towards the motion detector at a rate of -2 ft./s for three seconds. How far in feet Xavier from the motion detector when he finishes his walk?
Answer:
1 ft away from the motion detector.
Step-by-step explanation:
To calculate Xavier's distance we can assume that the motion detector would be represented as 0ft. Now we simply need to create the arithmetic expression for every step/action that Xavier performed. Finally, we would solve the expression to calculate Xavier's total distance from the motion detector.
5ft + (0.5ft * 4) + (-2ft * 3)
5ft + 2ft - 6ft
1ft
Finally, we can see that Xavier is 1 ft away from the motion detector.
