The diagonal length of a rectangular swimming pool can be represented by 10 times the square root of 5. Which expression represents this length?

Answer:

1010.33

(:

Step-by-step explanation:

Answer:

x³ - 3x² - 9x + 27

= x²(x - 3) - 9(x - 3)

= (x² - 9)(x - 3)

= (x -3)(x + 3)(x - 3)

= (x + 3)(x - 3)²

Answer:

3 squares

Step-by-step explanation:

Firstly, you have to count the number of squares in the shape. As it can been seen from the diagram, there are a total 18 squares (i.e 6 squares on each row × 3 squares on each column).

Secondly you have to find 1/6 of the total number of the squares in the shape. 1/6 of the total number of the square in the shape = 1/6 × 18 = 3 squares

Therefore 3 squares would have to be shaded so that 1/6 of the shape is shaded

i m sorry my small brother wrote it

It forms a right triangle.

To find X you can use the Pythagorean theorem which would be written as x^2 = a^2 + b^2

This can be rewritten as x = sqrt(a^2 + b^2)

Using the dimensions of the tree the answer would be :

B. x = sqrt(8^2 + 13^2)

The equation to find the length of the fallen part of the tree  is

[tex]x=\sqrt{8^2+13^2}[/tex]

Right triangles is a triangle with one angle is 90 degree.

The side opposite to 90 degree is the hypotenuse.

the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse .

The length of the fallen part of the tree is the hypotenuse

Hypotenuse is 'x'

Base of the triangle is 13 feet and height is 8 ft

Apply Pythagorean theorem to find out the hypotenuse 'x'

[tex]hypotenuse^2= base^2 + height ^2\\x^2=\sqrt{13^2+8^2} \\x=\sqrt{13^2+8^2}[/tex]

the equation to find the length of the fallen part is

[tex]x=\sqrt{8^2+13^2}[/tex]

Answer:

Percentage increase= 125%

Step-by-step explanation:

Giving the following information:

2018= 200 dogs

2019= 450 dogs

To calculate the percentage increase, we need to use the following formula:

Percentage increase= [(2019 - 2018)/2018]*100

Percentage increase= [(450 - 200)/200]*100

Percentage increase= 125%

Answer:

X=+4

y=-2

Step-by-step explanation:

this is simultaneous equations

hence,

using elimination method

3x+2y=5

2x+2y=4

2y eliminates 2y

3x+2x=5x=5*4

5x=20

X=20/5

X=+4

(2)

to find "y"

take any of the equation above

using equ(2)

2x+2y=4

2(4)+2y=4

+2y=+4-8

+2y=-4

y=-4/2

y=-2

hope it useful!

Answer:

7.06

Step-by-step explanation:

This triangle can be solved a couple of ways. In the end, they amount to the same thing.

1) The area is ...

A = 1/2bh = 1/2(8)(15) = 60 . . . using DG as the base

Using GE as the base, the height (DF) is ...

A = (1/2)(17)(DF)

2(60)/17 = DF = 120/17

DF ≈ 7.06

__

2) Using similar triangles, we can find the ratio of the long side to the hypotenuse as ...

(long side)/(hypotenuse) = DE/GE = DF/DG

DF = DG(DE/GE) = 8(15/17) = 120/17

DF ≈ 7.06

Answer:

15

Step-by-step explanation:

To find the rate of change, find the slope

Slope= [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

        [tex]=\frac{35-20}{2-1}\\\\=\frac{15}{1}\\\\=15[/tex]

Answer:

[tex]12^{2}[/tex]

Step-by-step explanation:

To find: a power that has a value greater than 140 and less than 145

Solution:

Take [tex]x=12^{2}[/tex]

Here,

[tex]12^{2}=144[/tex] and [tex]140<144<145[/tex]

That is [tex]140<x<145[/tex]

Therefore,

[tex]12^{2}[/tex] has a value greater than 140 and less than 145.

General Formulas and Concepts:

Pre-Algebra

Algebra I

Step-by-step explanation:

Step 1: Define systems

-5x - y = 12

y = -4x - 9

Step 2: Solve for x

Substitution

Step 3: Solve for y

Answer:

y = 8

x = 18

Step-by-step explanation:

(x + y = 26) x2 -1

2x+3y = 60 -2

2x+2y = 52 -1

2x+3y = 60 -2

Subtracting equation 2 from equation 1

= -y = -8

= y = 8

_____________________________________________________

2x+3y = 60

= 2x+3x8 = 60

= 2x+24 = 60

= 2x = 60-24

= 2x = 36

= x = 36/2

= x = 18  

Answer:

The second one y<2x-6

Step-by-step explanation:

Based on the shading we can tell that the sign is going to always be shaded on the right side. We see the line is dashed (its kinda hard to see) but a dashed line means none of the points on it can be part of the solution. If it was a solid line it would be ≤ and we see it's not so its <

Answer:

1: 80 degrees

Step-by-step explanation:

1:

Angle R is 130

Angle S is 60

Quadrilatural's angles add up to 360

360 - 130 - 60 = 170

In my opinion angle U looks like a right angle so 90 degrees.

170 - 90 = 80

so 80 degrees

Answer:

y = -.25x + 12

Step-by-step explanation:

Subtract x on both sides.

y = -.25x + 12

There is your answer. The "1" before the y doesn't need to be written, as a rule in algebra, ones do need to be written and are assumed to be there if there is no number at all.

-.25 is the slope and 12 is the y-intercept.

Step-by-step explanation:

Answer:y= (3/4)x -7/4

Step-by-step explanation:

[y -(-1)]/[x - 1] = [2 -(-1)]/[5 - 1]

[y + 1]/[x - 1] = 3/4

y + 1 = (3/4)x - 3/4

y = (3/4)x - 7/4.
