Answer:
Step-by-step explanation:
7259.75 - 7100 = 159.75
he earned 159.75 in interest
159.75/ 7100= .0225
and if you convert that to percentages then its 2.25%
Answer:a)9
I think
Step-by-step explanation:
If 1 of ur factors is 9...and the sum of ur factors is 13....then ur other factor is (13 - 9) = 4
so u have 2 factors, 9 and 4, and u r the product, then u r (9 * 4) = 36 <==
Given:
A line passes through (1,-2) and is perpendicular to
.
To find:
The equation of that line.
Solution:
We have, equation of perpendicular line.

Slope of this line is



Product of slope of two perpendicular lines is -1.



Now, slope of required line is
and it passes through (1,-2). So, the equation of line is

where, m is slope.





Therefore, the equation of required line is
.
8x - amount of boys
7x- amount of girls
8x + 7x = 195
15x= 195 ( divide by 15)
x= 13
8x = 8 x 13 = 104
7x = 7 x 13= 91
there are 104 boys, and 91 girls.
