Pamela's age is two times Jiri's age. The sum of their ages is 33. What is Jiri's age?
please please help
Answer:
Let Jiri's age be as 'x'
Therefore, Pamela's would be 2x
Since the addition of both is 72, the equation formed would be..
2x+ x =72
3x =72
x= 72÷3
x = 24 years.
Therefore, Jiri's age is 24 and Pamela's is twice of Jiri ie 48 years.

Find the measures of angles x and y in the figure.
Answer:
x = y = 60°
Step-by-step explanation:
The angle adjacent to 120° inside the triangle is
180° - 120° = 60°
The triangle is isosceles ( 2 congruent legs ) with the 2 base angles being congruent , then
y = 60°
The vertex of the triangle = 180° - (60 + 60)° = 180° - 120° = 60°
x is vertically opposite the vertex and is congruent , so
x = 60°

A sporting goods store is having a 15% off sale on all items. Which functions can be used to find the sale price of an item that has an original price of x ? You may choose more than one correct answer.
y = .85 x
ƒ( x ) = 1.15 x
Sale = Original - 15
ƒ( x ) = x - .15 x
Sale = Original - .15(Original)

A graph is shown below:
Whích of the following inequalities is best represented by this graph? (4 points)
Answer:
5x -y ≥ 2
Step-by-step explanation:
The slope of the boundary line is positive, so the x- and y-coefficients will have opposite signs when the equation is written in standard form (eliminates choices A, B).
The graph is shaded for x-values greater than those on the boundary line, so the form of the desired equation will be ...
ax -by ≥ c . . . . . for some positive values of a, b, c
This eliminates choice C and indicates the correct choice is the last one:
5x -y ≥ 2

FunctionFunctionNot a functionNot a function=================================================
Explanation:
Relation 1 is a function because any input item in the domain leads to exactly one and only one output item in the range. If we had say 2 arrows coming from "chair", and pointing to two different outputs, then we wouldn't have a function. It's perfectly possible to use words in place of numbers when talking about functions. All that matters is that we have one input map to exactly one output. Relation 2 is a function for similar reasoning as relation 1. It's possible to have an output repeated and still have a function. Relation 3 is not a function. Why not? Because of the points (j,v) and (j,t). The input j leads to more than output (v and t at the same time). A similar issue happens with the input 's' also.Relation 4 is also not a function. The repeated input this time is -5 which maps to the outputs z and 'a' at the same time.find the measure of all the angle b’s pls. pretty pretty please. if you do all four ily. #desperate.

Hello! My name is Galaxy and I'll be helping you today :D. I hope you are having a nice day.
Theorums
To solve the problem, since it is in the field of Geometry, there is bound to be theorums and basic knowledge that we need to know, upon seeing this problem what we need to know are:
Supplementary Angles: When two angles add up to 180 degrees.
Complementary Angles: When two angles add up to 90 degrees.
Interior/Exterior Angles Theorum.
Right Angles.
Solving
So to solve this, I'll first start with number 11. In this, we need to solve for B and we are given the first angle and b as the second angle.
What we can do is first we know that it is a Complementary angle as we know 65 degrees + b has to equal to 90 degrees.
Upon solving that, we know that B for the first one is
[tex]90=b+65\\b= 25[/tex]
We know that b is 25 degrees for the first one.
For the second one, we know that due to the interior/exterior angles theorem that 80 + b has to equal to 180 degrees due to the int/ext angles theorem and supplementary angles.
[tex]180=80+b\\b=100[/tex]
We know that b is 100 degrees.
For the third one, we know the entire thing is 360 degrees. Since we know that, we can solve for b as we have all the angles needed.
[tex]244+23+b=360\\b=93[/tex]
Upon solving, we know that b is 93 degrees.
For the final one, due to vertical angles, b is equal to 48 degrees!

What is the surface area of the cylinder with height 7 cm and radius 5 cm? Round
your answer to the nearest thousandth.
Answer:
376.991 cm²
Step-by-step explanation:
[tex]SA_{cylinder} = 2\pi r^{2} + 2\pi rh[/tex]
Surface Area = 2π(5²) + 2π(5)(7)
= 50π + 70π
= 120π
= 376.9911184... ≈ 376.991
Derive Surface Area of A CylinderIf you take a look at a net of a cylinder, you can see it is composed of two circles(bases) and a rectangular strip with the length of the diameter of the circle
The formula for the area of a circle = πr², and since there are 2, it is 2πr²
The formula for circumference of a circle = 2πr, and since we are multiplying that by the height by the height of the cylinder, it is 2πrh
∴ 2πr² + 2πrh

Step-by-step explanation:
Alecia runs the air conditioner im her home when it id hot outside. She uses the equation C = 0.01m to determine the cost , C , in dollars , to run the air conditioner for m minutes . According to the question what is the cost per minute of running alecia’s air conditioner?
The cost per minute is an illustration of proportionality constant.
The cost per minute is of running Alecia's air conditioner is $0.01
The cost function is given as:
[tex]\mathbf{C(m) = 0.01m}[/tex]
Where C represents the cost, and m represents the number of minutes
A proportional relationship is represented as:
[tex]\mathbf{y =kx}[/tex]
Where k represents the constant of proportion.
So, by comparison:
[tex]\mathbf{k = 0.01}[/tex]
In this case, the proportionality constant is the same as the cost per minute.
Hence, the cost per minute is $0.01

Answer: 54° or 40°, depending on my interpretation of the problem.
Step-by-step explanation:
I do not understand the drawing. I see a right angle with a line bisecting it at 36 degrees. A right angle is 90°, so the other angle should be (90 - 36) or 54°. But what's shown is (14 - 1)°, and I don't know how to interpret that. Is the "1" supposed to be an "x"? If so, x = 40°

Explain why opening a parachute can slow a skydiver down to a safe landing speed. You can add drawings to aid your explanation
Answer:
There is no air resistance acting in the upwards direction, and there is a resultant force acting downwards. ... There is no resultant force and the skydiver reaches terminal velocity. When the parachute opens, the air resistance increases. The skydiver slows down until a new, lower terminal velocity is reached.
