Answer:
42.8°
Step-by-step explanation:
The sine rule states that for a triangle with lengths of a, b and c and the corresponding angles which are opposite the sides as A, B and C, then the following rule holds:
[tex]\frac{a}{sin(A)}=\frac{b}{sin(B)} =\frac{c}{sin(C)}[/tex]
Given that points A, B and C forms a triangle with angle A = 65°, distance from A-to-C = 90 m and the distance from B to C = 120 m.
The distance from A to C is the side opposite to angle B. Hence let b = distance from A to C = 90 m.
The distance from B to C is the side opposite to angle A. Hence let a = distance from B to C = 120 m.
Therefore using sine rule:
[tex]\frac{a}{sin(A)}=\frac{b}{sin(B)} \\\\\frac{120}{sin(65)}=\frac{90}{sin(B)} \\\\sin(B)=\frac{90*sin(65)}{120} \\\\sin(B) =0.6797\\\\B=sin^{-1}(0.6797)\\\\B=42.8^o[/tex]

Answer:
x=16
Step-by-step explanation:
red line^2 = (8 x sq rt 3)^2 - 12^2
red line ^2=191.99-44
red line^2=47.99
red line=6.93
12/6.93=6.93/(x-12) by the geometric mean altitude theorem
12(x-12)=(6.93)(6.93)

Which distance measures 5 units?
A number line going from negative 8 to positive 8. A closed circle appears at negative 8 and is labeled W. A closed circle appears at negative 3 and is labeled X. A closed circle appears at positive 1 and is labeled Y. A closed circle appears at positive 5 and is labeled Z. An orange arrow line extends the length of the number line and contains all points.
A. the distance between points W and X
B. the distance between points X and Y
C. the distance between points X and Z
D. the distance between points Y and Z
Answer:
A. the distance between points W and XStep-by-step explanation:
Looking for the distance of 5 units
A. the distance between points W and X
-3 - (-8) = -3 + 8 = 5CorrectB. the distance between points X and Y
1 - (-3) = 1 + 3 = 4 < 5IncorrectC. the distance between points X and Z
5 - (-3) = 5 + 3 = 8 > 5IncorrectD. the distance between points Y and Z
5 - 1 = 4 < 5IncorrectFind the prime factorization of 54, and then write in Standard Form, Expanded Form, and Exponential Form.
Answer:
Step-by-step explanation:
2 * 3 * 3 * 3
The prime factors of 54 are given as the below listed.
Prime factors = 2 x 3 x 3 x 3
In factorisation and expansion, we can also write it as { 2, 3, 3, 3 }
If it needs to be written in exponential form, we have
Written in exponential form, we get 2^1 * 3³
If it needs to be written in standard form, we have, 5.4 * 10^1 or 54 * 10^
If need be and we are asked to find the expanded form which is

Select all statements in function notation that represent the situation.
Od(30) = d (70)
Id(10) = 20
Od (90) < d (160)
Id(t) = 10 when t is 20
Od (0) = 0
Id(0) = 170
Id(170) = 0
Answer:
:)
Step-by-step explanation:
d(0)=0
d(0)=170
d(90)<d(160)
d(t)=10 when t is 20
The true statements from the function are:
d(30) = d(70)d(10) = 20d(0)=0d(170) = 0.Functions can be represented as graphs and equations.
The equation of the graph is represented as:
[tex]y = d(t)[/tex]
From the graph, we have the following parameters
[tex]d(30) =d(70) = 40[/tex]
[tex]d(10) = 20[/tex]
[tex]d(0) = d(170) = 0[/tex]

Tommy is thinking about using three different sizes of soup cans. His first can has a volume of 24 pi inches cubed, and his second can has a volume of 50 pi inches cubed. Which of these cans will hold more soup than the other two cans Tommy is considering?
A)A cylinder with height 4 inches and radius 4 inches.
Step-by-step explanation:
Volume of a Cylinder = \pi r^2 h
Next, we determine the volume of the options being considered by Tommy.
Option A:
A cylinder with height 4 inches and radius 4 inches.
Volume =\pi *4^2*4=64\pi cubic inches
Option B
A cylinder with height 7 inches and diameter 4 inches.
Volume =\pi *2^2*7=28\pi cubic inches
Option C
A cylinder with height 5.5 inches and radius 3 inches.
Volume =\pi *3^2*5.5=49.5\pi cubic inches
Option D
A cylinder with height 6.5 inches and Base Area B = 4 pi inches squared.
Volume =4*6.5*\pi=26 \pi cubic inches
The cylinders in Option A will hold more soup than the other two cans Tommy is considering.

A. $13
B. $52
C. $39
Answer:
$39
Step-by-step explanation:
because there is 3 of them and they each pay $13 dollars just add it together or 13x3
Answer:
x = -3 and 52
Step-by-step explanation:
5x=2
subtract both sides by 5
5x-5 = 2-5
x = -3
2.
there are a total of 4 people because in the question it said mike and his 3 friends.
they each paid $13 and there are 4 people in total
we multiply 13 * 4 = 52

Distance (feet), x 1 2 3 4 3 Height (feet), y 5 6 7 8 9 Which of the following describes the table? A. a relation only B. both a relation and a function C. a function only D. neither a function nor a relation
Answer:
I think, Option B is correct..The table is a relation and a function
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as A
Now , the value of A is
f ( x ) = { 5 , 6 , 7 , 8 , 9 }
Now , the input values of the function are
x = { 1 , 2 , 3 , 4 , 5 }
where a relation is a set of ordered pairs (x, y) where there is a relationship between the first element (x) and the second element (y)
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Hence , the table is a function and relation
