Find the value of x for the triangle below.
Answer:
x = 10
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opposite/ hypotenuse
sin 30 = 5/x
Multiply each side by x
x sin 30 = 5
Divide by sin 30
x = 5/sin 30
x = 10
Answer:
Step-by-step explanation:
in the given triangle . one angle is 90 degree and other angle = 30
therefore third angle = 180 - 120 ( angle sum property of a triangle)
third angle = 60 degree
sin 30 = 5 / x (1)
cos 30 =third side /x (2)
from 1 * 2 we get ,
SIN 30 * COS 30 = 5/X * THIRD SIDE / X
1/2 *[tex]\sqrt{3}[/tex]/2 = 5 * THIRD SIDE / X^2
[tex]\sqrt{3}[/tex] * X^2/10 = THIRD SIDE
BY APPLYING PYTHAGORUS THEOREM
X^2 = 5^2 + [ [tex]\sqrt{3}[/tex] * X^2/10]^2
X^2 = 25 + 3x^4/100
x = square root of 25 + 3x^4/100 = 5+[tex]\sqrt{3}[/tex]x^2/10
x= 5+ [tex]\sqrt{3}[/tex] * x^2/10
Need help with the question, I already have the degree and leading coefficient but not the constant term for this polynomial. f(x) = −2 + x^3 −3x^7 + 6x^6 Degree: 7 Leading Coefficient: -3 Constant Term: ?
lizzy borrowed $900 at 18% interest for christmas gifts. how much will she owe in total after 3 years?
Answer:
$1478.73
Step-by-step explanation:
Use the compound amount factor and assume compounding once per year. Then:
A = $900(1 + 0.18)^3
= $1478.73 due after three years.
Answer:
= $1478.73 or = $1478.72
Step-by-step explanation:
Credit companies charge daily but you only mention yearly question so i will show you yearly and monthly and daily as 3 separate methods.
For years
we use the expression a x {(+1) + b} ^t = 900 x 1.18^3
For months
we use the expressions a x {( +1) +b ^t * 12
We keep to yearly interest
And prove 900 x 1.18^3 = 1478.7288
= $1478.73
Generally, credit companies round down to $1478.72
We work out a yearly rate = 18% interest and divide amount borrowed by 18%
900/18 = 50
then whatever is paid we minus this from the $900 = 900 x 50 = 45,000
50 x 365 = 18,250 owed if no payments were met if agreed to pay monthly but before end of the 3 year contract = meaning if paid at end of month 12- before start of month 13 the 360th day.
Write 5 as a ratio of two integers
The number 5 is a rational number, so you must be able to express it as a quotient, and you can. Dividing any number by 1 gives you the original number, so to express an integer like 5 as a quotient, you simply write 5/1. The same is true for negative numbers: -5 = -5/1
-5 = -5/1
Step-by-step explanation: I believe it’s this I had it right on my question.
// * PLEASE ANSWER * // AB is tangent to circle C. Find AC to two decimal places.
Answer:
19.92
Step-by-step explanation:
To find the length of AC we need to use the Pythagorean theorem: a^2 + b^2 = c^2
a = 6 b = 19
a^2 = 36
b^2 = 361
36 + 361 = 397
c^2 = 397
to find c we take the square root of 397
[tex]\sqrt{397} = 19.9248588452[/tex]

Expand and simplify a(t+4)-a(4-3t
Answer:
4at
Step-by-step explanation:
1. Distribute. You well get at+4a-4a+3at.
2. Eliminate the opposites (+4a and -4a cancel out to equal 0, which can then be excluded from the equation). You will get at+3at.
3. Add. at+3at=4at
Answer:
Step-by-step explanation:
Use distributive property
a(t+4) - a(4 - 3t) = a*t + a*4 +(- a) * 4 - (-a)*3t
= at+ 4a - 4a + 3at {combine like terms}
= at + 3at + 4a - 4a {add /subtract like terms}
= 4at

Answer:
x = 3
Step-by-step explanation:
Rectangle = length*width = 3(x+12) = 3x+36
Triangle = length*width/2 = 2x*5/2 = 5x
Since the rectangle is 3 times the triangle, thjat gives us:
3x+36 = 3(5x) -> 3x + 36 = 15x
Isolate x and solve:
36 = 12x
x = 3

A living room is 19 feet wide. The carpeted portion of the room is 5x feet long and the adjacent 9) tiled portion of the room is 7y feet long. Use the distributive property to find an expression for the
total area of the living room.
A) 95x + 133y square feet B) 24x + 26y square feet C) 228(x + y) square feet D) 95x + 7y square feet
Answer:
Option A. 95x + 133y square feet.
Step-by-step explanation:
Area of a rectangular room = Length × Width
Length of the room = Length of carpeted portion + Length of the tiled portion
= (5x + 7y) feet
Width of the living room = 19 feet
Area of the living room = (5x + 7y) × 19
= 95x + 133y Square feet [By distributive property]
Therefore, expression for the total area of the living room is option (A).

A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3.00 + 0.50 m = 9.50, where m represents the number of miles traveled. Which statement shows the meaning of the driver’s equation? Select two options. Three dollars added to $0.50 is the same as $9.50. Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents. Three dollars more than the quotient of $0.50 and the number of miles is nine dollars and fifty cents. The product of the number of miles and the sum of $3 and $0.50 is equal to $9.50. The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.
Answer: The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.
Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.
Step-by-step explanation:
Hi, to answer this question we have to analyze the equation given:
3.00 + 0.50 m = 9.50
Where m is the number of miles.
The equation states that the fixed fee charged (3.00) plus the product of the value of each mile traveled (0.50) and the number of miles traveled (m); is equal to 9.50.
So, the correct statements are:
The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents. Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.Feel free to ask for more if needed or if you did not understand something.
