Solve 5/(r-9)=8/(r+5)

Answers

Answer 1

Answer:

r = 32 1/3

Step-by-step explanation:

5/(r-9) = 8/(r+5)

cross multiply:

5 x (r + 5) = 8 x ( r - 9)

5r + 25 = 8r - 72

Add 72 to both sides:

5r + 97 = 8r

Subtract 5r from both sides

97 = 3r

Divide both sides by 3

r = 32 1/3

Answer 2

Answer:

r = 32 1/3 or 97/3

Step-by-step explanation:

Step 1: Cross-multiply.

[tex]5*(r+5)=8*(r-9)[/tex] [tex]5r + 25 = 8r - 72[/tex]

Step 2: Subtract 8r from both sides.

[tex]5r + 25 - 8r = 8r - 72 - 8r[/tex] [tex]-3r +25=-72[/tex]

Step 3: Subtract 25 from both sides.

[tex]-3r + 25 - 25 = -72 - 25[/tex] [tex]-3r = -97[/tex]

Step 4: Divide both sides by -3.

[tex]\frac{-3r}{-3}=\frac{-97}{-3}[/tex] [tex]r=\frac{97}{3}[/tex] [tex]r = 32\frac{1}{3}[/tex]

Therefore, r = 32 1/3 or 97/3.

Joseph traveled from Boston to Framingham at 50mph and then back to Boston at 40mph. What was Josephs's average speed on the round trip?
Plz help

Answers

Answer:

45mph

Step-by-step explanation:

To find the average speed, we must add together all of the different speeds and divide by the quantity of them (assuming all of them are equal in time). In this case we have 2: 50 and 40.

[tex]50+40=90[/tex].

Answer:

The quadratic x2 − 5x + 6 factors as (x − 2)(x − 3). Hence the equation x2 − 5x + 6 = 0

has solutions x = 2 and x = 3.

Similarly we can factor the cubic x3 − 6x2 + 11x − 6 as (x − 1)(x − 2)(x − 3), which enables us to show that the solutions of x3 − 6x2 + 11x − 6 = 0 are x = 1, x = 2 or x = 3. In this module we will see how to arrive at this factorisation.

Polynomials in many respects behave like whole numbers or the integers. We can add, subtract and multiply two or more polynomials together to obtain another polynomial. Just as we can divide one whole number by another, producing a quotient and remainder, we can divide one polynomial by another and obtain a quotient and remainder, which are also polynomials.

A quadratic equation of the form ax2 + bx + c has either 0, 1 or 2 solutions, depending on whether the discriminant is negative, zero or positive. The number of solutions of the this equation assisted us in drawing the graph of the quadratic function y = ax2 + bx + c. Similarly, information about the roots of a polynomial equation enables us to give a rough sketch of the corresponding polynomial function.

As well as being intrinsically interesting objects, polynomials have important applications in the real world. One such application to error-correcting codes is discussed in the Appendix to this module.

The numbers are measurements of radius diameter and circumference of circles A and B. Circle A is smaller than Circle B which number belongs to which quantity? 2.5, 5, 7.6, 15.2, 15.7, 47.7

Answers

Step-by-step explanation:

a diameter is always twice the radius.

the only pairs in this list, where one number is twice the other, is :

2.5 and 5

7.6 and 15.2

so,

2.5 is the radius of A

5 is the diameter of A

7.6 is the radius of B

15.2 is the diameter of B

15.7 is then the circumference of A (as the smaller of the remaining 2 numbers).

47.7 is the circumference of B.

this is also proven by the formula for the circumference of a circle : c = 2×pi×r
