The Pythagorean Theorem, given by the formula a^2+b^2=c^2, relates the three sides of a right triangle. Solve the formula for the positive value of a in terms of b and c.

Answers

Answer:

c=√a²b²

Step-by-step explanation:

The positive value of 'a' in terms of b and c will be [tex]a =\sqrt{b^2-c^2}[/tex].

What is the Pythagorean theorem?

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

It is given that the formula of the Pythagorean theorem for a right-angle triangle is, a² + b² = c².

The value of c is calculated as:-

a² + b² = c²

Reverse the equation to calculate a.

c² =  a² + b²

Taking to the left side then the equation will become:-

a² = c² - b²

Taking square root on both sides of the equation.

[tex]\sqrt{a^2}=\sqrt{c^2-b^2[/tex]

[tex]a = \sqrt{c^2-b^2}[/tex]

Therefore, the positive value of 'a' in terms of b and c will be [tex]a =\sqrt{b^2-c^2}[/tex].

Submit Answer

Answers

Answer:

$187

10b + 13c

Step-by-step explanation:

Payment for babysitting = $10 per hour

Payment for clearing tables = $13 per hour

How much money would Stella earn in a week in which she worked 7 hours babysitting and 9 hours clearing tables?

Total weekly payments = Payment for babysitting × number of hours + Payment for clearing tables × number of hours

= 10 × 7 + 13× 9

= 70 + 117

= $187

How much money would Stella

week in which she worked b hours babysitting and c hours clearing tables?

Total weekly payments = Payment for babysitting × number of hours + Payment for clearing tables × number of hours

= 10 × b + 13 × c

= 10b + 13c

A car went 64 miles on 2 gallons of gas in the morning, 16 miles on 1/2 gallon of gas at noon, and 32 miles on 1 gallon of gas at 5:00 PM. Is the amount of gas used proportional to the distance the car drove? Why or why not?

Answers

Answer:

Yes,

Step-by-step explanation:

You take 64 miles for 2 gallons and divide it by 2. And it leads up to 32 miles and 1 gallon. Now you divide that by 2 again and get 16 miles and 1/2 gallon. So, to check that you can take 16+16 and you get 32 and take 32+32 and you get 64.

The equation that models this relationship is y=2x. How many liters of water should Austin combine with 16 scoops of juice mix? Write your answer as a whole number or decimal.

Answers

Answer:

8 liters

Step-by-step explanation:

Given that:

y = 2x

where y is the number of scoops of juice mix, and x is the liters of water required.

To determine the liters of water required for 16 scoops of juice mix;

y = 16

So that,

16 = 2x

x = [tex]\frac{16}{2}[/tex]

  = 8

x = 8 liters

Therefore, Austin would combine 8 liters of water to the 16 scoops of juice mix.

Equation of the line = ?

Solution:

The equation of any straight line is often expressed as;

y and x are the coordinates

c is the intercept

  Now insert values of y, x and m to find c;

What is a system of equation?

A system of equations is used when there are two variables, and you are given two pieces of information about how those variables are related.

Given that, A combination of 3 erasers and 5 pencils cost $7.55. A combination of 6 erasers and 12 pencils cost $17.40.

Let e represents eraser and p represents a pencil.

Establishing the equations,

3e+5p = 7.55

6e+12p = 17.40

Solving by elimination, we get,

p = 1.15

Hence, The cost of each pencil is $1.15.

What is an angle ?

An angle is a mathematical term which we can defined, when two straight lines or rays meets at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.

Interior angles:- The  inner angle made by the intersection of two polygonal sides.

Exterior angles:-  The  outer angle made by the intersection of two polygonal sides.

Given that,

All the exterior angles are,

(5x + 4), (7x + 4),(4x + 9),(4x + 1),(9x-6)

It is known that,

Sum of Interior angle & Exterior angle is equal to 180°

So we can calculate all the Interior angles,

180°- (5x + 4),  180°-(7x + 4),   180°-(4x + 9),   180°-(4x + 1),    180°-(9x-6)

Formula for sum of all the Interior angles = (2n-4)×90

So, n=5

Sum of all the Interior angles = 540°

[180°- (5x + 4)] + [180°-(7x + 4)]+[180°-(4x + 9)]+[180°-(4x + 1)] +[180°-(9x-6)] = 540

900- 29x- 12 = 540

x = 12

Hence, The value of x is, 12
