Answer:
Hi! I think you are referring to the Pythagorean Theorem.
Essentially, given a right triangle, the sum of the squares of the shorter sides equals the square of the longer (slant) side or hypotenuse.
The formula is a squared + b squared = c squared
If the triangle has side lengths 3 and 4 (for the shorter sides), the longer side can be solved like this:
3 squared + 4 squared = x squared
(Let x = the longer side)
3 squared = 9
4 squared = 16
9+16 = x squared
25 = x squared
x = 5
So there you go, that's the Pythagorean theorem.
Let me know if this helped!
Answer:
a theorem attributed to Pythagoras that the square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.

Find slope and intercept of the line 3x - 2y - 7 = 0
The slope and intercept of the line 3x - 2y - 7 = 0 are -1.5 and -3.5 respectively
How to determine the slope and the intercept?The equation of the line is given as:
3x- 2y - 7 = 0
Add 7 to both sides
3x - 2y = 7
Subtract 3x from both sides
-2y = -3x + 7
Divide both sides by -2
y = -1.5x -3.5
A linear equation is represented as:
y = mx + c
Where m represents slope and c represents the intercept
By comparison;
m = -1.5 and c = -3.5
Hence, the slope and intercept of the line 3x - 2y - 7 = 0 are -1.5 and -3.5 respectively

How many hours must Miguel worked to receive $10,000 in total pay?
Using the linear equation, Miguel must work for 160 hours to receive $10,000 in total pay
Complete Question:Miguel works as a technician in a company. If his hourly rate and flat pay are $50 and $2000, how many hours must Miguel worked to receive $10,000 in total pay?
How to determine the number of hours?Let the number of hours be x and the total pay be y.
The equation that represents the total pay is represented as:
y = Rate * x + Base pay
From the question, we have:
Base pay = 2000
rate = 50.
So, we have:
10000 = 50 * x + 2000
Subtract 2000 from both sides
8000 = 50x
Divide both sides by 50
x = 160
Hence, Miguel must work for 160 hours

A grocery wants to make two kinds of coffee. One consoles for $1.40 pound, and the other cells for $2.95 a pound. He wants to makes a total of 21 pounds and sell it for $2.60 per pound. How many pounds of each kind should he use in the new mix? (round off the answers to the nearest hundredth)
Step-by-step explanation:
a lot of typos in the problem description.
I assume the price of the mix is 1:1 related to the prices of the individual types of coffee.
so, from what I understood we can define
x = pounds of the first type of coffee.
y = pounds of the second type of coffee.
x + y = 21 pounds
1.4x + 2.95y = 2.6(x + y) = 2.6×21 = $54.60
in the second equation we have to bring the given "$2.60 per pound" to the total price, which is $2.60 times the total amount of pounds (which is 21).
from the first equation we get
x = 21 - y
and that we use in the second equation
1.4×(21 - y) + 2.95y = 54.6
29.4 - 1.4y + 2.95y = 54.6
1.55y = 25.2
y = 25.2 / 1.55 = 16.25806452... ≈ 16.26 pounds
x = 21 - y = 4.741935484... ≈ 4.74 pounds
so, he should mix 4.74 pounds of the first (cheaper) type and 16.26 pounds of the second (expensive) type.
