A 12-foot ladder that is leaning against a wall makes a 75.5 degree angle with the level ground.
Which of the following equations can be used to determine the height y, above the ground, in feet, that the ladder touches the wall
A. Sin 75.5 = 12/y
B. Cos 75.5 = y/12
C. Sin 75.5 = y/12
D. Cos 75.5 = 12/y
Answers
Answer:
C. Sin 75,5 = y/12
Step-by-step explanation:
This angle can be calculated using the law of sine:
sin(angle)=opposite cathete/hypothenuse
sin(angle)=wall/ladder
In this exercise we want to calculate the height of the ladder, so the equation is changed afterwards.
sin(angle)=wall/ladder
sin(75,5°)=12ft/y
The height y above the ground in feet is ; (C ) sin 75.5 = y / 12
Determine the equation that can be used to determine y
The ladder, the horizontal ground and the vertical height above the ground form a right angle triangle are ;
The vertical height y = opposite
Length of ladder = hypotenuse
Horizontal ground = adjacent.
According to trigonometry, sine of an angle is opposite/hypotenuse
sin 75.5 = y/12.
In conclusion, the height y above the ground in feet is sin 75.5 = y / 12.

Step-by-step explanation:
The percent equation, 125 = n(50); 250%
What is percent?A number or ratio which can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it. There is no dimension to percentages. As a result, it is known as a dimensionless number. When we say a number is 50% of something, we mean that it is 50% of everything.
As in 0.6%, 0.25%, etc., percentages can also be expressed as decimals or fractions. The grades earned in any subject have been calculated in terms of percentages in academics.
Let the required percentage be x%.
A/c to question,
[tex]\frac{x}{100} * 50= 125\\\\ x=250[/tex]
That is, required percentage is 250%.
Hence, option C is correct.

Which single conversion factor would you use to find out how many miles are in 8,462 yards?
Answers
Answer:
A. 1 mile / 1,760 yards
Step-by-step explanation:
A single conversion factor is a number that we can multiply directly with 8,462 yards to determine how many yards are there in 8,462 yards.
Since 1 mile is to 1,760 yards, the single conversion factor to use in determining how many miles a number of yards would be = 1 mile/1,760 yards = [tex] \frac{1}{1,760} [/tex]
Thus, to find out many miles are in 8,462 yards, multiply by [tex] \frac{1}{1,760} [/tex].
[tex] 8,462*\frac{1}{1,760} = \frac{8,462}{1,760} = 4.8 [/tex] miles

Can someone help me know how to do this problem In finding what I can put in for (c) in order to get 2 imaginary solutions
Answers
Answer:
To get 2 imaginary solutions, c must be less than -2
Step-by-step explanation:
The general form of the quadratic equation is:
[tex]ax^2+bx+c=0[/tex]
Solve the quadratic equation by using the formula:
[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
The equation to solve is:
[tex]-2x^2+4x+c=0[/tex]
In our equation: a=-2, b=4, c=unknown
For the roots to be imaginary, the argument of the square root must be negative, that is:
[tex]b^2-4ac<0[/tex]
Substituting the known values:
[tex]4^2-4(-2)c<0[/tex]
[tex]16+8c<0[/tex]
Subtracting 16:
[tex]8c<-16[/tex]
Solving:
[tex]c<-2[/tex]
Thus, to get 2 imaginary solutions, c must be less than -2

We went to the market to buy some fruit. We decided to buy some apples, strawberries, and oranges. If we buy 2 apples, 3 boxes of strawberry, and 4 oranges, the fruit would cost $15.30. If we buy 1 box of strawberry, 4 apples, and 2 oranges, the fruit would cost $10.90. If we buy 1 orange, 5 apples and 2 boxes of strawberry, the fruit would cost $13.70.
Answers
Answer:
The answer is below
Step-by-step explanation:
Let x represent the cost of apples, y represent the cost of strawberries and z represent the cost of oranges.
The money used to buy 2 apples, 3 boxes of strawberry, and 4 oranges is represented as:
2x + 3y + 4z = 15.3 (1)
The money used to buy 4 apples, 1 boxes of strawberry, and 2 oranges is represented as:
4x + y + 2z = 10.9 (2)
The money used to buy 5 apples, 2 boxes of strawberry, and 1 oranges is represented as:
5x + 2y + z = 13.7 (3)
Solving equation 1, 2 and 3 simultaneously gives:
x = $1.5, y = $2.5 and y = $1.2
The cost of orange is $1.5, cost of strawberry = $2.5 and cost of orange = $1.2
The price of stock market in at 9 AM was 13.17 then the price has been increasing at a rate of 0.11 each hour at noon the price of stuff he was 13.67 it begins to decrease at the rate of 0.12 each hour if the two rates continue and how many hours were the prices of the two stocks with the same
Answers
Answer:
2.26 hours
Step-by-step explanation:
Given that:
Stock 1:
Initial price = 13.17
Rate of increase = $0.11 per hour
13.17 + 0.11h - - - (1)
Stock 2 :
Initial price = 13.69
Rate of decrease = 0.12 per hour
13.69 - 0.12h - - (2)
13.17 + 0.11h = 13.69 - 0.12h
0.11h + 0.12h = 13.69 - 13.17
0.23h = 0.52
h = 0.52 / 0.13
h = 2.26 hours
