a total of $9500 is invested, part at 10% simple interest and part at 9%. if the total annual return from the two investments is

Nutka1998 [239]

a total of $9500 is invested, part at 10% simple interest and part at 9%

if the total annual return from the two investments is $914.00

Amount invested = 9500

Total amount return means total yield = $914

Let x amount is invested at 10% simple interest

Interest for first part = 10 % times x = 0.10x

Remaining part invested is 9500 -x

Interest for remaining amount = 9% (9500 -x) = 0.09(9500-x)

Total interest yield is 914. Now we frame an equation

0.10x + 0.09(9500-x) = 914

0.10x +855 - 0.09x = 914 (combine like terms)

0.01 x + 855 = 914 (subtract 855)

0.01x = 59 ( divide both sides by 0.01)

So x = 5900

$5900 is invested in 10% simple interest

9500 - 5900 = $3600 is invested in 9% simple interest

The Dowers make pumpkin pie. If each person wants three slices of pie, and each pie is Cut into 9 slices, how many pies do they

Mrac [35]

The Dowers need to make 5 pies for 15 people.

Step-by-step explanation:

Given,

1 person = 3 slices of pie

15 persons = 15*3 = 45 slices of pie

It is also given that;

9 slices of pie = 1 whole pie

1 slice of pie = $\frac{1}{9}\ pie$

45 slices of pie = $\frac{1}{9}*45$

45 slices of pie = 5 whole pies

The Dowers need to make 5 pies for 15 people.

Slope of (-20,9) (14,9)

skelet666 [1.2K]

Y2-y1/x2-x1 is slope so

9-9/14-(-20) so you get 0/34 which means there is no slope since they have the same y (the equation would be y=0x+9 therefore y=9)
Which makes sense since the equation is a straight line
