Answers
[tex]\\ \tt\hookrightarrow sin\theta=\dfrac{P}{H}[/tex]
[tex]\\ \tt\hookrightarrow sin47=\dfrac{50}{h}[/tex]
[tex]\\ \tt\hookrightarrow h=\dfrac{50}{sin47}[/tex]
[tex]\\ \tt\hookrightarrow h=\dfrac{50}{0.73}[/tex]
[tex]\\ \tt\hookrightarrow h=68.4ft[/tex]
Answer:
sine
sin = o/h
Step-by-step explanation:
The ladder leaning against the building has created a right triangle.
A right triangle is made up of 2 legs (at 90° to each other) and a hypotenuse (longest side).
Trig ratios help us calculate side lengths and interior angles of right triangles:
sin(x) = O/Hcos(x) = A/Htan(x) = O/Awhere x is the angle, O = the side opposite to the angle, A = the side adjacent to the angle, H = hypotenuse
From inspection of the diagram, we need to find the hypotenuse (H) and we have been given the angle (x) and the side opposite to the angle (O):
Therefore, we can use the trig ratio sin(x) = O/H to determine H:
⇒ sin(47) =50/H
⇒ H = 50/sin(47)
⇒ H = 68.36637305... = 68 ft (nearest foot)

Use intercepts to graph the linear equation 4x+6y=12 .
Answers
Answer:
The Y Intercept is -2 and the slope is 4/6.
Step-by-step explanation:
First, you need to convert that equation into y = mx + b. To do that you need to bring the 6x over on the other side first. 6y = 4x - 12 is what you get.
Then you need to get rid of the 6, you divide it into the 4 and 12 to do that.
You get y = 4/6x - 2.
Your slope is 4 rise and 6 run.
Your Y-intercept is negative 2.
Answer:
First, put it into a graphing form:
4x + 6y = 12
6y = -4x + 12
y = -2/3 + 2
(I would graph this but it`s not letting me attach an image. I`ve laid out the steps below)
- Make a point at (0,2). It`s two units above the origin. This is your y-intercept.
- Move the dot two units down, and three units right. It should end up on the point mentioned in the next step
- Make another point at (3, 0). It`s three units to the right of the origin. This is your x-intercept.
- Continue moving two down , three right until that side of the graph is done.
- Go back to the y-intercept and move two units up, and three units left, until the line reaches the edge.
- Once you have the dots down, connect them with a ruler.
The easier way to do this is by just taking two points, and going all the way across the graph, but it`s not always accurate.
y-intercept = (0,2)
x-intercept = (3,0)

One building is 60 stories tall, and a second building is 48 stories tall. What is the ratio, in simplest terms, of the number of stories in the first building to the number of stories in the second building?
Answers
Answer:
Ratio is : 5/4 or 5 : 4
Step-by-step explanation:
The ratio of the number of stories in the first building to the number of stories in the second building :
60 : 48 or 60/48
Both numbers have 3 and 4 as common factors. So
3 * 4 * 5 : 3 * 4 * 4
5 : 4 is the ratio in the simplest terms striking of the common factors.
Answer:
Simplest form is 60 : 48.Step-by-step explanation:
We are finding the ratio of 60 and 48.
It's very simple.
Ratio should be:
60 : 48.There is no other simple form, so the simplest form is 60 : 48.

2813 English books
Step-by-step explanation:
Hindi books are 42% of 4850
42 ÷ 100 = 0.42
0.42 × 4850 = 2037 Hindi books
number of English books = total number of Hindi and English books - number of hindi books
4850 - 2037 = 2813 English books

Find five consecutive odd integers if the sum of the first three integers is 7 more than the sum of the last two.
Answers
Answer: 15, 17, 19, 21, 23
Step-by-step explanation:
You can let the middle number = x, then the numbers are
x-4, x-2, x, x+2, x+4
Plugging it back in to what is given,
x-4+x-2+x = 7+x+2+x+4
3x-6 = 2x + 13
x = 19
The numbers are 15, 17, 19, 21, 23
The first odd integer is 15, and the five consecutive odd integers are 15, 17, 19, 21, 23
What is Sequence?Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
Let x be the first odd integer, then the next four odd integers would be x+2, x+4, x+6, and x+8.
According to the problem, the sum of the first three integers is 7 more than the sum of the last two, which can be expressed mathematically as:
x + (x+2) + (x+4) = (x+6) + (x+8) + 7
Simplifying the equation, we get:
3x + 6 = 2x + 21
Subtracting 2x and 6 from both sides, we get:
x = 15
Therefore, the first odd integer is 15, and the five consecutive odd integers are 15, 17, 19, 21, 23

This situation can be represented by the equation 7p–11=73.
The cost of each pair of pants is $12.
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that George buys 7 pairs of pants and uses a discount for $11 off. He spends $73 total.
We can write the equation as -
7p - 11 = 73
7p = 84
p = 12

assume your salary was $30,000 in 2010 and $40,000 in 2012. if your salary follows a linear growth pattern, what will your salary be in 2015?
Answers
30,000 * 1.08^3 = 37,791.36.
because of inflation, if something cost 30,000 today, it will cost 37,791.36 three years from now.
in order to pay for that same things three years from now, you need to be making 37,791.36 dollars.
your salary needs to grow by 8% a year just to keep up with inflation.
if you make less, you lose buying power.
if you make more, you gain buying power.
