Find the values of x and y in the diagram.
Step-by-step explanation:
the triangle URT is an Equilateral triangle so all angles are equal to 60°
and the full triangle UTS is a right angle .
5y= 90-60= 30°
y= 6
and since the triangle RST is an Isosceles triangle
so the angle RST and RTS are equal .
in this case =30° .
[tex] \sin(30) = \frac{x - 7}{11 + x - 7 } \\ \sin(30) = \frac{x - 7}{x + 4} \\ 0.5 = \frac{x - 7}{x + 4} \\ 0.5(x + 4) = (x - 7) \\ 0.5x + 2 = x - 7 \\ 0.5x = 9 \\ x = 18[/tex]

3. A bicycle wheel has a diameter of 559 mm and has 32 equally spaced spokes. What is the approximate arc
length, rounded to the nearest hundredth, between each spoke? Use 3.14 for it. Show your work.
Answer:
Arc length = 54.85mm
Step-by-step explanation:
360/32 = 11.25
11.25 * 559 = 6288.75
6288.75 * 3.14 = 19746.675
19746.675/ 360 = 54.851875
Rounded to the nearest hundredth
Arc length = 54.85mm

Step-by-step explanation:
HERE,
redius of a circle (r)=14 meters.
we know that,
[tex]\boxed{\red{\sf{circle~ circumference=2\times \pi \times r }}}[/tex]
According to the question,
circle circumference=
[tex]\tt{2\times \pi \times 14 }[/tex][tex]\tt{2 \times \dfrac{22}{7} \times 14 }[/tex]
[tex]\tt{2 \times \dfrac{22}{\cancel{7}} \times \cancel{14}}[/tex]

A teacher wants to investigate whether listening to music while taking a math test increases scores. He instructs half
of his 36 students to listen to music while taking a test and the other half to not listen to music during the test. To
determine who listens and who does not, the teacher identifies the two students who scored highest on the last test
and randomly instructs one to listen to music and one to not. The teacher does the same for the next two highest-
scoring students and continues in this manner until each student has their instructions. Which of the following best
describes this plan?
O This is a cluster sample.
O This is an observational study.
O This is a stratified random sample.
O This is an experiment with blocking.
O This is a completely randomized experiment.

What is the value of the x variable in the solution to the following system of equations? (5 points)
4x − 3y = 3
5x − 4y = 3
x can be any number as there are infinitely many solutions to this system
There is no x value as there is no solution to this system
−3
3
Answer:
D. 3Step-by-step explanation:
Given system:
4x − 3y = 3 5x − 4y = 3Solve for x by elimination method:
Multiply the first equation by 4 and the second equation by 3:
4(4x - 3y) = 4(3) ⇒ 16x - 12y = 123(5x - 4y) = 3(3) ⇒ 15x - 12y = 9Subtract the second equation:
16x - 12y - 15x + 12y = 12 - 9x = 3Correct option is D
Answer:
x=3Step-by-step explanation:
to understand thisyou need to know about:system of linear equationPEMDASsolving system of linear equation using substitution methodgiven:4x − 3y = 3
5x − 4y = 3
let's justify how many solutions the system of linear equation hasa system of linear equation has one solution when
[tex] \frac{ a_{1} }{a_2} ≠ \frac{b_1}{b_2} [/tex][tex] \frac{4 }{5} ≠ \frac{ - 3}{ - 4} [/tex]
therefore
this system of linear equation has only one solution
let's figure out x using substitution method:4x − 3y = 3.......1
5x − 4y = 3.......2
get from 1st equation
[tex]4x - 3y = 3 \\ - 3y= - 4x + 3 \\ y = \frac{ - 4x + 3}{ - 3 } \\ y = \frac{4}{3} x - 1[/tex]
[tex]subsitute \: got \: volue \: of \: y \: into \: 2nd \: equation[/tex]
[tex]5x - 4( \frac{4}{3} x - 1) = 3 \\ 5x - \frac{16}{3} x + 4 = 3 \\ 5x - \frac{16}{3} x = - 1 \\ \frac{15x - 16x}{3} = - 1 \\ - x = - 3 \\ \huge \therefore \: x = 3[/tex]

Answer:
Step-by-step explanation:
4x-2 +3x+7 = 180
7x + 5 = 180
7x = 175
x = 25
3(25) + 7 = 82
Answer:
82 (degrees)
Step-by-step explanation:
4x-2+3x+7=180=7x+5...175=7x...x=175/7... x=25
This is both angles combined which we know adds up to half of the entire quadrilateral (180 degrees). Then solve.
3(25) +7=82 which is equal to f
f=82

Michelle is playing a number guessing game where you must guess the two numbers she is thinking about and gives two hints. The first hint is that the sum of two numbers is 50. The second hint is the first number is 43 less than twice the second number. What are the two numbers?
Answer:
The two numbers are a = 57 and b = -7
Step-by-step explanation:
Let's write the first sentence into an equation.
A) The sum of two numbers is 50
[tex]a+b=50[/tex] (1)
B)The first number is 43 less than twice the second number.
[tex]a=43-2b[/tex] (2)
Now, we just need to solve the system of equations (1) and (2)
Let's put (2) into the (1)
[tex]43-2b+b=50[/tex]
[tex]43-b=50[/tex]
[tex]b=43-50[/tex]
[tex]b=-7[/tex]
Using this value in (1) we can find a
[tex]a-7=50[/tex]
[tex]a=57[/tex]
Therefore, the two numbers are a = 57 and b = -7
I hope it helps you!
