Answer:
3/4, 18/24, 27/36, 36/48
Step-by-step explanation:
9 and 12 can both be divided by 3 to equal 3/4
9/12 times 2 is 18/24
9/12 times 3 is 27/36
9/12 times 4 is 36/48
hope this helps:)
At a certain time of day, a tree that is x meters tall casts a shadow that is x - 23 meters long. If the distance from the top of the tree to the end of
the shadow is x + 2 meters, what is the height, x, of the tree?
Answer:
The height, x of the tree is 35 meters
Step-by-step explanation:
use Pythagorean theory to answer
(x+2)^2= x^2+(x-23)^2
[tex]x^{2}[/tex]+4x+4=[tex]x^{2}[/tex]+[tex]x^{2}[/tex]-46x+529
re-arrange the equation and collect like terms
[tex]x^{2}[/tex]-50x+525=0
(x-35)(x-15)=0
x=15 or x=35
x cannot be 15 because 15-23 is a negative answer
therefore the height of tree is 35 m
Which of the following equations is an example of inverse variation between
the variables x and y?
A. y = 12x
B. y =х
12
C. y= x + 12
D. y = 12
х
Answer:
The correct answer is option D
Step-by-step explanation:option A : y = x/12 ⇒ x = 12y (wrong option)
option B : y = 12/x ⇒ y * x = 12 (wrong option) and c will be equal 12
option C : y = x + 12 ⇒ not similar to the general form (wrong option)
option D : y = 12/x (corect option)( I meant to switch it around)
The general form of inverse variation between the variables x and y is as following:
where c is constant
So, the correct option is D

What is the axis of symmetry for f(x) = 2x2 − 4x + 5? x = −2 x = −1 x = 1 x = 2
Step-by-step explanation:
for a quadratic equation
y = ax² + bx + c
the x value for the axis of symmetry is
x = -b/(2a)
in our case
y = 2x² - 4x + 5
a = 2
b = -4
x = - -4/4 = 4/4 = 1
x = 1 is the correct answer.

The sum of 2 [tex]\frac{1}{3}[/tex] and 5/6 times 8/3 is 4 [tex]\frac{5}{9}[/tex].
What is a expression? What is a mathematical equation? What is Equation modelling ?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is 4 [tex]\frac{5}{9}[/tex] is the same as the sum of 2 [tex]\frac{1}{3}[/tex] and 5/6 times a number
Assume the number to be [x]. Then, we can write -
41/9 = 7/3 + 5x/6
41/9 - 7/3 = 5x/6
(41 - 21)/9 = 5x/6
20/9 = 5x/6
x = 20/9 x 6/5
x = 4/3 x 2
x = 8/3
Therefore, the sum of 2 [tex]\frac{1}{3}[/tex] and 5/6 times 8/3 is 4 [tex]\frac{5}{9}[/tex].

Find the volume of the sphere. **30 points**
Either enter an exact answer in terms of pi or with 3.14
Radius=8
Answer:
The volume of the sphere is 2,143.57
Step-by-step explanation:
The formula for finding the volume of the sphere is
V = [tex]\frac{4}{3}[/tex]π[tex]r^{3}[/tex]
"r" represents the radius of the sphere. So put the value of it in the formula.
V = ([tex]\frac{4}{3}[/tex])(3.14)([tex]8^{3}[/tex])
V = ([tex]\frac{4}{3}[/tex])(3.14)(512)
Multiply all of them and you will get:
2143.57333333 or 2,143.57 which is the volume of the sphere

GIVING 100 POINTS AND BRAINLIEST IF CORRECT! You recently upgraded your experience by buying an Controller for $74.99 and an Game Pass Subscription for $14.99 per month.
Answer:
Part A: It's linear because it increases at a constant rate of 14.99 dollars per month
Part B: C = 14.99M + 74.99 (y = 14.99x + 74.99)
Step-by-step explanation:
Part A: Every month, you have to pay the same amount.
1 month = 14.99
2 months = 14.99 + 14.99
3 months = 14.99 + 14.99 + 14.99
So, it's linear.
Part B: We have to use the formula y = mx + b, or slope-intercept form, to represent the total cost per month.
m = slope, b = y-intercept (initial value)
Let's have the total cost be represented as C
Let's also have the subscription per month be represented as M
So, C would = 74.99, because we only need to pay for a controller once
But we also our subsription per month, M, as 14.99.
So our final answer would be C = 14.99M + 74.99, or y = 14.99M + 74.99 if you can't make your own variables
I wanted to get more indepth. Try adding this to notes! <3
