Find the altitude of the triangle.
30 degrees
Hypotenuse of 14
Answer:
Approx. 12.124 units tall
Step-by-step explanation:
Since you need to find the height (which is adjacent to the given angle), you need to use cosine (adj. over hypotenuse).
cos(30) = x/14
Multiply both sides by 14:
14cos(30) = x

Answer:
15:2
Step-by-step explanation:
If you take 45 / 6 you will end up with 7.5
You can't have a ratio with a fraction. So to get a whole number you multiply 7.5 by 2 to get a full number. Therefore 15:2

Answer:
5. 70°
6. 69°
7. 17°
8. 37°
Step-by-step explanation:
Problems 5, 7, 8 have the opposite side and adjacent side given. You know that ...
Tan = Opposite/Adjacent
Then the angle measure is ...
angle = arctan(Opposite/Adjacent)
__
Problem 6 gives the opposite side and the hypotenuse. The sine relation is involved there:
Sin = Opposite/Hypotenuse
Then the angle measure is ...
angle = arcsin(Opposite/Hypotenuse)
__
5. ? = arctan(93/34) ≈ 70°
6. ? = arcsin(42/45) ≈ 69°
7. ? = arctan(11/35) ≈ 17°
8. ? = arctan(22/29) ≈ 37°
A new linear road is planned to be constructed perpendicular to an existing one. On a representative grid, a surveyor determines that the existing linear road passes through the points LaTeX: (4,7)( 4 , 7 ) and LaTeX: (2,15)( 2 , 15 ). The roads must intersect at the point LaTeX: (4,7)( 4 , 7 ).
(a) Determine the slope of the new road.
(b) Determine the equation of the new road.
a) The slope of the new road is given by m = -4
b) The equation of line is y = -4x + 32
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be represented as P ( 4 , 7 )
Let the second point be represented as Q ( 2 , 15 )
Now , the slope is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 15 - 7 ) / ( 2 - 4 )
Slope m = 8 / -2
Slope m = -4
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 4 = ( -4 ) ( x - 7 )
On simplifying the equation , we get
y - 4 = -4x + 28
Adding 4 on both sides of the equation , we get
y = -4x + 32
Hence , the equation of line is y = -4x + 32

The length of a rectangular garden is 3 feet less than twice its width. If 48 feet of fencing is used to enclose the garden, what are the dimensions of the garden?
Answer:
my names jeff
Step-by-step explanation:
Answer:
Step-by-step explanation:
So its a rectangle which means it has 4 sides
two of the sides are x feet long
and two of them are 2x -3 feet long
we also know that all of the sides together are 48 feet long
so the equation would look like
2(x)+2(2x-3)=48
or x+x+2x-3+2x-3=48
It doesn't matter which one you use because they both simplify to
6x-6=48
add 6 to both sides
6x=54
divide both sides by 4
x=9

A study was conducted with the objective of determining the effect of two different strength-training programs, one involving the use of a balance ball and the other using stationary exercise equipment, on blood pressure and cholesterol levels in women over the age of 60. Eighty women over the age of 60 were identified and randomly divided into two equal-sized experimental groups. Each member of the two groups was trained and allowed to follow the prescribed routine for 8 weeks. The subjects were aware of the purpose of the study but not that there were two different treatment groups involved. The cholesterol levels and blood pressure for subjects were measured at the start and at the end of the 8 weeks. The experimenter and the medical technician were not told to which group any of the subjects were assigned. This is an example of an attempt to conduct

On the planet Gespli, there are 10 pisquets to every 7 vreels. if farmer Frank has 40 vreels on his rew farm, how many pisquets are on the farm
Answer:
57 pisquets
Step-by-step explanation:
Ratio of pisquets:vreels = 10:7
Ratio on Frank's rew farm: x:40
since ratios are equivalent, you'd so the same on both sides. To get from 7 to 40 u multiply by a number, so to get from 10 to x u have to multiply by that same number. To find this number, divide 40 by 7: 40/7 = 5.7
Then, multiply this by 10: 5.7 x 10 = 57
there are roughly 57 pisquets on his farm.

x = 104 degrees
Step-by-step explanation:
A line like this will always have a measure of 180 degrees, therefore when the two sides are combined, it must equal 180, which means you can set up an equation and x can be determined
72 + x + 4 = 180
76 + x = 180

7. Marie can make 12 small mango pies for every 10 mangoes. How many pie
A. Marie can make 30 pies.
C. Marie can make 50 pies
B. Marie can make 40 pies.
D. Marie can make 60 pies
sorry putol po kasi eto
Answer:
D. Marie can make 60 pies.
Step-by-step explanation:
In this problem, we know that amount of small mango pies is directly proportional to the amount of mangoes. The amount needed for preparing an amount of pies is calculated by simple rule of three:
A. Marie can make 30 pies.
[tex]x = \frac{10\,mangoes}{12\,pies}\times 30\,pies[/tex]
[tex]x = 25\,mangoes[/tex]
25 mangoes are required for producing 30 pies.
B. Marie can make 40 pies.
[tex]x = \frac{10\,mangoes}{12\,pies}\times 40\,pies[/tex]
[tex]x = 33.333\,mangoes[/tex]
34 mangoes are required for producing 40 pies.
C. Marie can make 50 pies.
[tex]x = \frac{10\,mangoes}{12\,pies}\times 50\,pies[/tex]
[tex]x = 41.667\,mangoes[/tex]
42 mangoes are required for producing 50 pies.
D. Marie can make 60 pies.
[tex]x= \frac{10\,mangoes}{12\,pies}\times 60\,pies[/tex]
[tex]x = 50\,mangoes[/tex]
50 mangoes are required for producing 60 pies.
The complete statement is: Marie can make 12 small mango pies for every 10 mangoes.How many pies can she make with 50 mangoes.
Hence, correct answer is D.

smaller possible number =
larger possible number =
Answer:
The largest possible number is 24, the smallest possible number is -6.
Step-by-step explanation:
maths
Smaller possible number = -6 and larger possible number = 24.
What is an absolute value?
The absolute value of a number is the distance value from zero without considering the sign of a number. It is also represented as |x|, where x is any number.
Given:
The distance between two numbers on the number line is 15.
And the distance between the numbers is the absolute value.
And one of the numbers is 9.
Let x and -x are the numbers.
So, when the number is x,
distance,
x-9 = 15.
x = 24
And when the number is -x,
distance,
9 -(-x)= 15.
x = -6.
Therefore, the possible integers are -6 and 24.

The phone lines to an airline reservation system are occupied 61% of the time. Assume that the events that the lines are occupied on successive calls are independent. If 11 calls are placed, what is the probability that the lines are occupied for exactly 5 calls
Answer:
0.1373 = 13.73% probability that the lines are occupied for exactly 5 calls
Step-by-step explanation:
For each call, there are only two possible outcomes. Either the lines are occupied, or they are not. The events that the lines are occupied on successive calls are independent. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
The phone lines to an airline reservation system are occupied 61% of the time.
This means that [tex]p = 0.61[/tex]
If 11 calls are placed, what is the probability that the lines are occupied for exactly 5 calls
This is P(X = 5) when n = 11. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 5) = C_{11,5}.(0.61)^{5}.(0.39)^{6} = 0.1373[/tex]
0.1373 = 13.73% probability that the lines are occupied for exactly 5 calls
