The formula is
A=p e^rt
A future value 1649
P present value 100
R interest rate?
T time 10 years
E constant
Solve the formula for r
R=[log (A/p)÷log (e)]÷t
R=(log(1,649÷100)÷log(e))÷10
R=0.28×100
R=28%

Last year Golden State Warriors won 80% of the first 15 matches. Then they won the rest of the three matches. What percent of al
MrMuchimi

Answer:

83.33%

Step-by-step explanation:

We first need to evaluate 80% of the first 15 matches in order to determine the number of watches out of 15 which they won.

80 % of 15 = 80/100 * 15 = 12

12 matches out of the first 15 were won.

Since the team won the rest of the 3 remaining matches, the total number of matches won becomes;

12 + 3 = 15

The team thus won 15 matches out of a total of 15 + 3 =18 matches .

The percent of all matches won is ;

15/18 * 100 = 83.33%

Help easy question!!

When you look at the x = 0 and y = -2, that is the y-intercept since the x = 0.

Then when you look at the second one, it goes right one and up four.

As rise over run, it would be 4 / 1 or simply 4.

The slope is 4 and the y-intercept is -2

Plug it in the equation: y = mx + b. M is the slope and B is the y-intercept.

y = 4x -2

If the measure of angle 4 is 11x and angle 3 is 4x , what is the measure of angle 3 in degrees?
fgiga [73]
<span>Answer:
   Let x = degree measure of the angle
    So, the complement of the angle has degree measure 90-x
    4/11 = x/(90-x)
    4(90-x) = 11x
    360 - 4x = 11x
    15x = 360
    x = 24°
    Supplement = 180 - x = 156° x/(180-x) = 24/156 = 2/13</span>
