Answer:

120 feet

Step-by-step explanation:

because 60 feet  x2 is 120

The distance between the first and the last tree is 132 feet.

An arithmetic progression(A.P.) is a series, where the difference between consecutive numbers is constant.

The first term of an A.P. is denoted by a, and the common difference is denoted by d.

The nth term of an A.P. series is found using the formula:

aₙ = a + (n-1)d.

The sum of n terms of an A.P. series is found using the formula:

Sₙ = (n/2)(2a + (n-1)d)

We are said that every tree is equally spaced. So the distance between the trees is in arithmetic progression.

With the first tree being at 0 feet from itself, our a = 0.

The distance from the first tree to the sixth tree is 60 feet, so we can say that the 6th term is 60

6th term = a + 5d

or, 60 = 0 + 5d

or, d = 60/5 = 12 feet.

To find the distance between the first tree and the last tree(12th tree), we will find the 12th term of the series,

12th term = a + (12-1)d = 0 + 11(12) = 132 feet.

∴ The distance in feet between the first and last tree is 132 feet.

Im not completely sure what this question is asking, however I'll try...

Well, if the length is in feet and the width is in feet, that would conclude that the perimeter would also be in feet. If you're asking for the actual number answer for what the perimeter is, I will not be able to help since there is a lack of information; you can only determine the perimeter when given the exact number of feet, both the width and length are.

Hi!

Given:

The first equation we can make can use the total number of tickets. The total number of tickets would be equal to the number of student tickets plus the number of adult tickets, correct? Therefore:

[tex]x+y=2400[/tex]

Now, the second one can use the profit and the price of each ticket. The number of student tickets multiplied by 3 (for the price) plus the number of adult tickets multiplied by 5 would be equal to the total profit. Hence:

[tex]3x+5y=9000[/tex]

Therefore, your system of equations is:

[tex]x+y=2400[/tex]

[tex]3x+5y=9000[/tex]

Answer: B, C, E, and F.

itis not similar as ratio of corresponding sides is not equal.

4/2=2

6/4=3/2

8/6=4/3

2≠3/2≠4/3

Step-by-step explanation:

since the polynomial is in the form

+x² - nx - m

we know that we are looking for 2 factors of x (to create x²).

and they must be in the form of

(x + a)(x - b)

to create the negative "m" at the end.

and "b" must be larger than "a" to create the negative "n" in the middle.

let's do the multiplication and compare the parts with our actual expression :

(x + a)(x - b) = x² - bx + ax - ab = x² + (a - b)x - ab

so, we know now in numbers that

-ab = -44

ab = 44

and

a - b = -7

a = b - 7

the short solution here is trial and error with the factors of 44 :

44 = 1×44 = 2×22 = 4×11

ah, only one combination has a difference of the factors of 7 or -7 : 4 and 11.

since b has to be larger (as a - b = -7), we have a = 4 and b = 11

and the factorization of our original expression is

f(x) = (x + 4)(x - 11)

FYI

if there is not such a short list of options to try, we can also go the full formal way :

we can use the second equation as identity in the first equation and get

(b - 7)b = 44

b² - 7b = 44

b² - 7b - 44 = 0

by the way, it is not surprising that it looks the same way as the original expression in x, because the factorization uses exactly the zero solutions for the original expression.

anyway, the formal solution to a quadratic equation of

ax² + bx + c = 0 is

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = b (the variable of our equation above)

a = 1

b = -7

c = -44

b = (7 ± sqrt((-7)² - 4×1×-44))/(2×1) =

= (7 ± sqrt(49 + 176))/2 = (7 ± sqrt(225))/2 =

= (7 ± 15)/2

b1 = (7 + 15) / 2 = 22/2 = 11

b2 = (7 - 15) / 2 = 8/2 = 4

based again on the original equations and the fact that b has to be the larger number, we get again (of course) that b1 is the valid solution and

b = 11 and a = 4

Step-by-step explanation:

All the roots of the provided function If f(1) is equal to the zero are -3, -1 and 1.

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).

The function given in the problem is,

[tex]f(x)=x^3+3x^2-x-3[/tex]

If f(1) = 0

[tex]f(1)=(1)^3+3(1)^2-(1)-3\\f(1)=1+3-1-3\\f(1)=0[/tex]

Thus, (x-1) is one of the factor of polynomial. Equate the polynomial equal to the zero, to find other roots as,'

[tex]x^3+3x^2-x-3=0\\x^2(x+3)-1(x+3)=0\\(x+3)(x^2-1)\\(x+3)(x+1)(x-1)=0[/tex]

Equate all the groups to zero to find the roots as,

[tex]x+3=0, x=-3\\x+1=0, x=-1\\x-1=0, x=1[/tex]

Hence, all the roots of the provided function If f(1) is equal to the zero are -3, -1 and 1.

The z-probability for the condition -0.78 ≤ z  ≤ 1.16 is 66%.

A z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.

It is given that

-0.78 ≤ z  ≤ 1.16

We have to find the p-value corresponding to -0.78 ≤ z  ≤ 1.16.

This means, p(-0.78 ≤  z ≤ 1.16)

p(0.78≤ z ≤1.16) can be written as p(z ≤ 1.16) - p(z ≤ -0.78)

p(0.78≤ z ≤1.16) =  p(z ≤ 1.16) - (1-p(z ≤ 0.78))

p(0.78≤ z ≤1.16) =  p(z ≤ 1.16) -1 + p(z ≤ 0.78)

From the standard normal table,

p(z ≤ 1.16)=0.87698

p(z ≤ 0.78)=0.78230

So, p(0.78≤ z ≤1.16)= 0.87698-1+0.78230

p(0.78≤ z ≤1.16) = 0.65928≈0.66 i.e 66%

Therefore, the z-probability for the condition -0.78 ≤ z  ≤ 1.16 is 66%.

The length of the missing side of the polygon with an area of 426 inches² is  31 inches.

Polygon is a 2-dimensional shape. They are made of straight lines.

Therefore,

area of the polygon = 426 inches²

The composite figure can be divided into two rectangle. Therefore,

area = area of rectangle 1 + area of rectangle 2

area of rectangle = lw

where

Therefore,

let

the unknown side = x

426 = 26 × 11 + (26 - 19) (x - 11)

Step-by-step explanation:

Given;

Kyle has 13 notebooks (1 for each class) and he puts 5 stickers on each one

Solve;

If Kyle wants to put 5 stickers on each of his 13 classroom notebooks, then we simply multiply 5*13 to find out how many stickers he will use in total.

5 * 13 =65

Kyle used 65 stickers total.

Then, to find out how many sheets he used, we will simply divide the total amount of stickers (T) by the amount of stickers on a sheet (S).

T = 65

S = 10

65/10 = 6.5

Thus, He will need 7 sheets, but will only use 6 and a half sheets.

Answer:

length= 108 feet,

width= 50 feet

Overview of steps:

Working:

Let the length and the width of the rectangle be L and W feet respectively.

L= 2W +8 -----(1)

Perimeter= 2(length) +2(width)

316= 2L +2W

2L +2W= 316

Divide both sides by 2:

L +W= 158 -----(2)

Substitute (1) into (2):

2W +8 +W= 158

Simplify:

3W +8= 158

3W= 158 -8

3W= 150

Divide both sides by 3:

W= 150 ÷3

W= 50

Substitute W= 50 into (1):

L= 2(50) +8

L= 100 +8

L= 108

Thus, the rectangle's length is 108 feet, and its width is 50 feet.
