A ladder leans up against a wall and makes a 60 degree angle with the ground. If it reaches 90 ft. up the wall, how long is the ladder? Round to the nearest tenth​

Answers

Answer 1

Answer:

The length is approximately 103.92 ft

Step-by-step explanation:

The angle the given ladder makes with the ground = 60°

The height to which the ladder reaches. h = 90 ft.

Assumption;

The angle formed between the wall and ground = 90°

The shape formed by the length, l, of the ladder the height to which the ladder reaches on the wall, h, and the ground, b, is a right triangle, with the length, l, of the ladder facing the 90° angle and the height, h, facing the 60° angle.

By sine rule, we have;

l/sin(90°) = h/sin(60°)

Therefore, the length l = sin(90°) × h/sin(60°) = 1 × 90/(sin(60°)) = 90/((√3)/2) = 2 × 90/√3 ≈ 103.92

The length, l ≈ 103.92 ft.

"15. Jorge is getting a loan from the bank for a new car. The loan amount is $25,000. The bank will compound the interest annually for 6 years at 4%. What will be the total amount of the loan at the end of the 4 years?"

the expression for compound interest is given as

A=P(1+r)^t

given data

Principal P=$25000

rate r=4%= 0.04

time t= 4years

Substituting into the expression we have

A=P(1+r)^t

A=25000(1+0.04)^4

A=25000(1.04)^4

A=25000x4.80

A=$120000

The total amount of loan after 4 years is $120000

Step-by-step explanation:

11y and 3d are not divisible

The given expression 3x + 11y can not be factored.

What is factorization?

In mathematics, factorization or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind. For example, 3 × 5 is a factorization of the integer 15 and is a factorization of the polynomial x² – 4.

To factor the expression it should have a degree of 2. So that we can split it into two parts called a factor.

The given expression is 3x + 11y.  The expression can not be factored in because of having a degree of 1.

Therefore, the given expression 3x + 11y can not be factored.

What is the relationship between the slopes of two perpendicular lines?

Answers

relation between two slopes of two perpendicular line are equal.

The relationship between the slopes of two perpendicular lines is that the product of the slopes of the two lines is equal to -1.

What are perpendicular lines?

Two geometric objects are perpendicular in elementary geometry if they intersect at a right angle. When two lines cross at a straight angle, they are said to be perpendicular.

The relationship between the slopes of two perpendicular lines is that the product of the slopes of the two lines is equal to -1. Therefore, assuming that there are two lines that are perpendicular to each other such that the slope of the two lines is m₁ and m₂. Therefore, we can write the relation as,

m₁ × m₂ = -1

Hence, the relationship between the slopes of two perpendicular lines is that the product of the slopes of the two lines is equal to -1.

A water park sold 39 child tickets and 36 adult tickets. What percentage of the tickets sold were child tickets?

Answers

Answer:

39 / 36 = 108.333333333333%

Step-by-step explanation:

A fraction consists of two numbers and a fraction bar:

39/36

The number above the bar is the numerator: 39

The number below the bar is the denominator: 36

Divide the numerator by the denominator to get fraction's value:

Val = 39 ÷ 36

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% = p/100 = p ÷ 100.

Calculate fraction's value.

Divide the numerator by the denominator to get fraction's value:

39/36 =

39 ÷ 36 ≈

1.083333333333333

Note:

100/100 = 100 ÷ 100 = 100% = 1

Multiply a number by the fraction 100/100,

... and its value doesn't change.

Calculate the percent value:

1.083333333333333 =

1.083333333333333 × 100/100 =

(1.083333333333333 × 100)/100 ≈

108.333333333333/100 =

108.333333333333% ≈

108.33%;

In other words:

1) Calculate fraction's value.

2) Multiply that number by 100.

3) Add the percent sign % to it.

Answer:

The length of a garden is 10 feet longer than three times the width. The perimeter of the garden is 240 feet. Find the length and the width of the garden.

Answers

Answer: width = 27.5 feet and length = 92.5 feet

Step-by-step explanation:

Let width = x, then length = 3x+10

Perimeter of rectangle = 2 (length +width)

Given:  Perimeter of the garden = 240 feet.

Then, [tex]2 (x+3x+10)=240[/tex]

[tex]\Rightarrow\ 2 (x+3x+10)=240\\\\\Rightarrow\ (4x+10)=120\\\\\Rightarrow\ 4x=110\\\\\Rightarrow\ x=\dfrac{110}{4}=27.5[/tex]

i.e. width = 27.5 feet

Then, length = 3(27.5)+10= 82.5+10=92.5 feet

Hence, width = 27.5 feet and length = 92.5 feet

Point B (−6,3) is reflected across the line y = x. What are the coordinates of the image B′?


The coordinates of the image B′ are (
A ,
B ).

Answers

Answer:

B'(3, -6)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to  new location. If an object is transformed then all its points are transformed. Types of transformation are rotation, reflection, dilation and translation.

Reflection is the flipping of a point over the line of reflection. If a point X(x, y) is reflected across the line y = x,  the new location is at X'(y, x).

If point B(-6, 3) is reflected over line y = x, the new location is B'(3, -6).
