Answer:
y = a ÷ (πx)
Step-by-step explanation:
An equivalent equation solved for y is:
y = a/πx
What is an equation?An equation is a pair of algebraic equations with the equal sign (=) in the middle and the same value.
The formula a = xy, where x and y are the halved lengths of the ellipse's biggest and smallest diameters, may be used to calculate the area, a, of an ellipse.
Starting from the formula a = πxy, we can rearrange it to solve for y:
a = πxy
Dividing both sides by πx, we get:
a/πx = y
y = a/πx
Therefore, an equivalent equation solved for y is:
y = a/πx.

Answer:
5 and 0
Step-by-step explanation:
The answer to x > -45, are all number that are larger than -45.
5: Is 50 larger than -45
-100: Is 55 smaller than -45
-50: Is 5 smaller than -45
0: Is 45 larger than 45
5 and 0 are correct because they are both larger than -45.
Answer:
Well from the question I can only confirm that X (-45, infinity) is the possible answer. The answer would be A and D because 5 is greater than -45, while 0 is also greater than -45.

At a certain company, the monthly salary of project managers can be modeled by the function f(x)= x^4 -10x^2+10,000 where x is the number of years of employment. After how many years would a project manager be eligible for a $20,000 monthly salary?
Answer:
Given
Step-by-step explanation:
Given the monthly salary of project managers modeled by the function
f(x)= x^4 -10x^2+10,000
To know the number of years that a project manager be eligible for a $20,000 monthly salary, we will substitute f(x) = 20,000 and solve for x as shown:
20,000 = x^4 -10x^2+10,000
x^4 -10x^2 = 20000-10000
x^4 -10x^2 = 10,000
x^4 -10x^2 - 10,000 = 0
(x^2)^2-10x^2 - 10000 = 0
let P = x^2
P^2 - 10P -10000 = 0
P = 10±√10²-4(-10000)/2
P = 10 ±√100+(40000)/2
P = 10 ±√40100/2
P = 10 ±200.2/2
P = 210.2/2
P = 105.1
Since P = x^2
105.1 = x^2
x = √105.1
x = 10.25
Hence it will take like after 10 years for the manager to earn a $20,000 monthly salary

Step-by-step explanation:
In a test, 5 marks are given for every correct answer and (-2) marks are given for every incorrect answer. 1) Anjali scored 30 mark. If she got 10 correct answers, how many questions she answered incorrectly? 2) Rohan got 4 correct answers. If he scored (-12) marks in the test, how many questions he answered incorrectly?
Answer:
1. Anjali answered 10 questions incorrectly
2. Rohan answered 16 questions incorrectly
Step-by-step explanation:
1 .The mark given for one correct answer = 5
That means that the mark given for 10 correct answers = 5 × 10 = 50
But Anjali's score = 30
Also, the marks gotten for incorrect answers = 30 - 50 = -20
Mark given for one incorrect answer = -2.
Therefore, number of incorrect answers would be;
= (-20) ÷ (-2)
= 10
•Anjali answered 10 questions incorrectly.
2. Total marks = -12
Number of correct answers = 4
Total marks for correct answers = 4 × 5 = 20
Also, marks for incorrect answers = -2 × Number of incorrect answers
Therefore,
Total marks = Marks for the correct answers + Marks for the incorrect answer
-12 = 20 + (-2) × Number of incorrect answers
-12 - 20 = -2 × Number of incorrect answers
-32 / 2 = Number of incorrect answers
Number of incorrect answers = 16
• Rohan answered 16 questions incorrectly.

The volume of a box is 1800 cubic Inches. If the length of the box is 10 inches and its width is 3 inches more than its height, find the width and
height of the box.
Answer:
The width of the box is 15 inches and its height is 12 inches
Step-by-step explanation:
Equations
The volume of a box of width W, height H, and length L is given by:
V=W*L*H
We know
L=10 inches
W=H+3
V=1800 cubic meters
Substituting:
1800=(H+3)*10*H
Operating and swapping sides:
[tex]10H^2+30H=1800[/tex]
Dividing by 10:
[tex]H^2+3H=180[/tex]
Rearranging:
[tex]H^2+3H-180=0[/tex]
Factoring:
(H-12)(H+15)=0
The only positive and valid result is:
H=12 inches
Thus,
W=H+3=12+3=15 inches
The width of the box is 15 inches and its height is 12 inches

Answer:
Jim ran 60 miles
Step-by-step explanation:
T (Toby) - 5 miles
K (Katie) - 4T , 4(5), 20
J (Jim) - 3K, 3(20), 60
Answer:
Jim ran 60 miles.
Step-by-step explanation:
First off I would take note of the information given.
Toby = t
Kate = k
Jim = j___________________________________________
j = 3k
t = 5
4t = k
Since we already know Tim ran 5 miles we multiply 5 x4 to get 20. So Kate ran 20 miles.
3 times Kate's amount is Jim's. So 20 x 3 = 60.

A lawnmower that regularly sells for $150 is on sale for $120. The price was decreased by percent.
Step 1:
Let us first find the decrease in amount.
Decrease in amount = 150 -120 = $30
Step 2:
Now let us find the ratio of decrease in price to original price.
So the ratio is 1/5 or in decimal its 0.2.
Step 3:
To find percentage decrease we change this decimal number 0.2 two places to the right side, so it becomes 20 %
The price decreased by 20%
