you didn’t put the picture :LOL:
The equation is 3n - 5 1/2. 5 1/2 = 5.5
3n - 5.5
n could equal 1 so, 3 x 1 - 5.5 = -2.5
3n - 5 1/2 = -2.5
Answer:
The amount is $2572.93 and the interest is $572.93.
Step-by-step explanation:
STEP 1: To find amount we use formula:
A=P(1+rn)n⋅t
A = total amount
P = principal or amount of money deposited,
r = annual interest rate
n = number of times compounded per year
t = time in years
In this example we have
P=$2000 , r=6.5% , n=1 and t=4 years
After plugging the given information we have
AAAA=2000(1+0.0651)1⋅4=2000⋅1.0654=2000⋅1.286466=2572.93
STEP 2: To find interest we use formula A=P+I, since A=2572.93 and P = 2000 we have:
A2572.93II=P+I=2000+I=2572.93−2000=572.93
Let Angle A = X
Since Angle B is the same, angle B is also X
Then angle C = X +45
Add the 3 angles together: X +X +X +45 = 3x+45
That equals 180 degrees:
3x+45 = 180
Subtract 45 from both sides:
3x = 135
Divide both sides by 3:
X = 135/3
X = 45
Angle A = 45
Angle B = 45
Angle C = 45+45 = 90
Answer:
$38.40
Step-by-step explanation:
20% of $48 is 9.60
48- 9.60= 38.40
