So lets remember the formula for interest first.
#lightbulb
here it is <span>A = P(1 + rt)
all we really have to do is plug in our rates, principles, and time into equation.
P = $800
t = 2 years 
r = 6.5% or as a decimal 0.065
now lets look at our new equation that finally has numbers in it

A = 800[1 +(0.065)(2)] first lets take care of the 0.065 and 2 by multiplying them together. thus our new equation.
A = 800(1+ 0.13) then we add the 1 to the 0.13 and get 1.13 
800(1.13) from here we just multiply  and that equals 904
since we are looking for what is earned we take 904 and subtract 800 to get that answer. Here is the math.

904 - 800 = 104 
he made 104 dollars in 2 years! 
hope this is right.
have a good one:)

merry christmas:D

Write the equation for a line perpendicular to y=-3x+18 that goes through the point (-12,6)
Hatshy [7]

Answer:

y=\frac{1}{3} x -14

Step-by-step explanation:

The equation of the line you will find should be in the form y =mx+c , where m is the gradient and c is the y intercept.

The gradient of a line that is perpendicular to a line [of a known gradient] is the negative reciprocal of the gradient of the first. i.e. if a is the known gradient and the perpendicular gradient is b, ab = -1. Therefore the -3b=-1 and b= 1/3

you can now write y = mx +c as y = 1/3x +c

As you have been given a coordinate, you can input these values into y= 1/3x + c

-12 = 1/3(6) +c

-12 - 2 = c

c = -14

hence the equation of the line is y= 1/3x -14

Which situation is best represented by the following equation?
Gennadij [26K]

Answer:

D

Step-by-step explanation: because W in the equation is the number of weeks she paid for the self defense class. and the 12.50 would be the registration fee because that  is added on top of the number of 40w.

40w + 12.50 = 492.50

         -12.50       -12.50

40w = 480.00

w = 12 which is how many weeks she paid

A right triangle has side 10 and hypotenuse 26. Use the Pythagorean Theorem
alekssr [168]

Answer:

24

Step-by-step explanation:

The Pythagorean Theorem states that a^{2} +b^{2} =c^{2} where a and b are the legs in a right triangle and c is the hypotenuse. Therefore, just substitute the values a = 10 and c = 26 into the equation to get b = 24

Hope this helps :)
