what was the interest rate if your balance on an investment of 857 dollars at the end of six years is 1268.36 dollars​
Mumz [18]
<h3>The interest rate is 8 % if your balance on an investment of 857 dollars at the end of six years is 1268.36 dollars​</h3>

<em><u>Solution:</u></em>

Given that,

Principal = $ 857

Amount = $ 1268.36

Number of years = 6

Rate of interest = ?

Simple Interest = Amount - principal

Simple Interest = 1268.36 - 857

Simple Interest = 411.36

<em><u>Use the formula,</u></em>

Simple Interest = \frac{ p \times n \times r}{100}\\\\411.36 = \frac{ 857 \times 6 \times r}{100}\\\\41136 = 5142 \times r\\\\r = \frac{41136}{5142}\\\\r = 8 \%

Thus the interest rate is 8 %

The area of circle B is 45x ____. The ratio of circle A to Circle B
Leokris [45]

Answer:

<h3>a) 3/4</h3><h3>b) 4:3</h3>

Step-by-step explanation:

Find the diagram attached.

Given the scale factor of circle A to circle B as 3/4

A:B = 3:4

Total ratio = 3+4 = 7

Area of bigger square A = 45sq. units;

The Total area can be gotten using the expression;

\frac{4}{7} \times x = 45 where;

x is the total area of both circles.

Get x;

\frac{4}{7} \times x = 45\\4x = 7 \times 45\\4x = 315\\x = \frac{315}{4}\\x =  78.75

Area of circle B = 78.75 - 45 = 33.75

Let the fraction required be y

45 * y = 33.75

y = 33.75/45

y = 3375/4500

y = 45/60

y = 3/4

Hence the area of circle B is 45 * <u>3/4</u> of circle A

b)The ratio of circle A to Circle B is expressed as;

Ratio = Area of circle A/Area of circle B

Ratio = 45/33.75

Ratio = 45 * 100/3375

ratio = 4500/3375

Ratio = 4:3

Hence the ratio of circle A to Circle B is 4:3

Slope intercept form of points (0,4) and (1,3
AnnyKZ [126]

Answer:

y = -x+4

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

   = ( 4-3)/(0-1)

   = 1 /-1

  = -1

The y intercept is (0,4) or 4

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = -x+4
