If Athlete J continues at that speed, it will take 12 minutes to run 1 mile
It will take Athlete J 60 minutes to run 5miles
Since the speed of Athlete H is greater than that of J, hence Athlete H runs faster.
The formula for calculating the speed of the athlete is expressed as:
Speed = Distance/Time
1) If Athlete J runs 2/3 of a mile in 8 minutes, this can be expressed as:
2/3 miles = 8 minutes
If the athlete runs for 1 mile, then;
1 mile = x
Divide both expressions
2/3 = 8/x
2x = 24
x = 12 minutes
Hence If Athlete J continues at that speed, it will take 12 minutes to run 1 mile
2) if athlete J run 5 miles, the time taken will be expressed as;
2/3(5) = 8/x
2/15 = 8/x
2x = 120
x = 60minutes
Hence it will take Athlete J 60 minutes to run 5miles
3) If Athlete H runs 2 3/4 miles in 1/2 hour, then the speed of athlete H will be expressed as:
Speed = (2 3/4)/0.5
Speed = 2.75/0.5
Speed = 5.5miles/hr
For Athlete J;
Speed = 5/1
Speed = 5 miles/hr
Since the speed of Athlete H is greater than that of J, hence Athlete H runs faster.

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

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

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

Identify the parent function for the function g(x) = x2 - 4 based on its function rule.
Then graph g and identify the transformation of the parent function that it
represents.
linear; translation up 4 units
quadratic; translation up 4 units
quadratic; translation down 4 units
O
linear; translation down 4 units
Answer:
Parent function is g(x) = x² a quadratic
Step-by-step explanation:
quadratic; translation down 4 units
-4 means the vertex will move down 4
The transformation of the parent function that represents translation down 4 units. Therefore, quadratic; translation down 4 units.
The given function is g(x)=x²-4.
What is the parent function?A parent function is the simplest function that still satisfies the definition of a certain type of function. For example, when we think of the linear functions which make up a family of functions, the parent function would be y = x. This is the simplest linear function.
Quadratic; translation down 4 units:
The parent function of the quadratic family is f(x) = x2. A transformation of the graph of the parent function is represented by the function g(x) = a(x − h)² + k, where a ≠ 0.
The transformation of the parent function that represents translation down 4 units. Therefore, quadratic; translation down 4 units.

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

How many people would all of the sheet cakes sold in problem 3 feed?
--------------------------------------------------------------------------------------------------------
(Dont need to tell me the answer just tell the steps I need to do)
Answer:
The chef sold 17 small sheet cakes. One small sheet cake can feed 12 people, so the small sheet cakes she sold can feed 17*12 people, which is 204 people. Do this for the medium and large sheet cakes as well, and add them up, and you'll get the answer.

Kara has five exam scores of 93, 67, 82, 71, and 94 in her biology class. What score does she need on the final exam to have a mean grade of 80?
Round your answer to two decimal places, if necessary. (All exams have a maximum of 100 points.)
Answer:
She needs at least 73%
Step-by-step explanation:
1. add all of the numbers up and d the quantity to find
93+67+82+71+94/5
=407/5
=81.
2. try diffrent numbers
407+73/6
=480/6
=80
She needs at least 73%
Answer:
A score of 73
Step-by-step explanation:
Five exam scores + the final exam = mean (average) of 80.
First find the total points that you need to make an 80 average 80 × 6 = 480 points.
The five exam scores + x score = 480 points.
93 + 67 + 82 + 71 + 94 + x = 480
407 + x = 480
x = 480 - 407
x = 73
