11. A large pine tree was struck by lightning and fell as
shown by the diagram below. Which equation
could be used to find the length of the fallen part of
the tree?
8 ft
13 ft —
A. 82 +132 - X
B. N82+132 -
C. 132 - 82 = X
D. V132 - 82 - *

Answers

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 Triangle.

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

The side opposite to 90 degree is the hypotenuse.

Pythagorean Theorem

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]

What is the length of DF? Round to the nearest hundredth.

Answers

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

baskets; some were 2-point shots, and the rest were 3-point shots. How
many 2-point shots did the team make?

Answers

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

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Algebra I

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

-5x - y = 12

y = -4x - 9

Step 2: Solve for x

Substitution

Substitute in y:                              -5x - (-4x - 9) = 12Distribute negative:                      -5x + 4x + 9 = 12Combine like terms:                      -x + 9 = 12Subtract 9 on both sides:             -x = 3Divide -1 on both sides:                x = -3

Step 3: Solve for y

Define original equation:                    y = -4x - 9Substitute in x:                                     y = -4(-3) - 9Multiply:                                                y = 12 - 9Subtract:                                               y = 3

how many squares would have to be shaded to that 1/6 of the shape is shaded

Answers

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

Jaylen has a pet grooming business. In 2018, he groomed 200 dogs. In 2019, he groomed 450 dogs. What was the percent increase in the number of dogs groomed? Don't forget your % sign.

Answers

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%

A school play sells adult and child tickets. On Friday they sold 55 child tickets and 20 adult tickets for $200. On Saturday they sold 72 child tickets and 36 adult tickets for $306. What is the cost of a child ticket?

Answers

Answer:

$2

Step-by-step explanation:

Let, price of individual child ticket is $x, and price of individual adult ticket is $y.

Now, on Friday we can write an equation is 55x+20y=200....(1).

and on Saturday we can write an equation is 72x+36y=306.....(2).

so, Equation 1: 55x+20y=200

 

Equation 2: 72x+36y=306

now, we are going to solve both equations.

after solving you will find x=2 and y=4.5

Hence, we can say that the cost of child ticket is $2, and the cost of adult ticket is $4.50.

The cost of a child's ticket will be $2.

On Saturday we can write an equation is 72x+36y=306.....(2).

The first equation is:-

55x+20y=200

The second equation will be written as:-

72x+36y=306

Now, we are going to solve both equations. After solving you will find x=2 and y=4.5

Hence, we can say that the cost of a child ticket is $2, and the cost of an adult ticket is $4.50.
