If r and s are positive integers, each greater than 1, and if 11(s-1) =13(r-1), what is the least possible value of (r+s)?
Tresset [83]

Answer:

The least value of (r+s) is (12+14)=26

Step-by-step explanation:

Well, first let us solve equation of 11(s-1)=13(r-1), which results in 11s-11=13r-13. Hence, 11s+2=13r. It is stated that r and s both are integers and greater than 1.

To make sure that r and s are integers, the least value of s must be equal to 14 (s=14) then the least value of r becomes 12 (r=12).

Finally, the least value of (r+s) is (12+14)=26.

Find the simple interest: Principal: $3020 Interest Rate: 5% Time: 6 months​
Andrews [41]

Answer:

A = $3094.58

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS

<u>Algebra I</u>

Simple Interest Rate Formula: A = P(1 + r)ⁿ

  • A is the final amount
  • P is the principal amount
  • r is the rate
  • n is the time (in years)

Step-by-step explanation:

<u>Step 1: Define variables</u>

A = ?

P = 3020

r = 0.05

t = 6 months = 0.5 years

<u>Step 2: Solve for </u><em><u>A</u></em>

  1. Substitute:                    A = 3020(1 + 0.05)^0.5
  2. Add:                              A = 3020(1.05)^0.5
  3. Evaluate:                       A = 3020(1.0247)
  4. Multiply:                        A = 3094.58

And we have our final answer!

Answer:

It's a square; vertice f is 6 units to the right of vertice e and g is 6 units above f, and h is 6 units to the left of g. This means there are four sides of equal length, with equal angles.

do you need more than that?

Varies directly means
if y varies directly as x that means
y=kx where k is a constant


so
y=kx
y=2 and 2/3 when y=1/4 then find k
convert 2 and 2/3 to imporoper fraction for ease
2 and 2/3=6/3+2/3=8/3

8/3=k(1/4)
multiply both sides by 4/1 to clear fraction
32/3=k

so now we have
y=(32/3)x

when x=1 and 1/8
find y
convert 1 and 1/8 to imporopor=9/8

y=(32/3)(9/8)
y=(288)/(24)
y=12
