Answer:
$9.47
Step-by-step explanation:
Add all her purchases together
97.62 + 22.95 + 14.78 = 135.35
The total tax is 6.5% sales tax, and 0.5% country tax
6.5% + 0.5% = 7%
Multiply the total amount spent by the total tax
Remembering that you need to convert the 7% into an integer, by simply diving by 100 first
135.35 * 0.07 = 9.47
Answer:
y - Q = -5/2(x - P)
Step-by-step explanation:
The equation of a line in point slope form is expressed as y - y0 = m(x-x0)
(x0, y0) is the point
m is the slope
Given the equation
y = 2/5x− 4.
Slope m = 2/5
Slope of the perpendicular line = -1/(2/5) = -5/2
Point;
x0 = P
y0 = Q
Substitute into the formula;
y - y0 = m(x-x0)
y - Q = -5/2(x - P)
This gives the required equation

Step-by-step explanation:
91/70=(29+x)/40
An expression to represent a decimal between 1 and 10 multiplied by ten. basically to write larger numbers with less digits.
ex . 100 = 1 x 10^2
ex. 4321= 4.321 x 10^3
