Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1 + r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = £600
r = 3.2% = 3.2/100 = 0.32
n = 1 because it was compounded once in a year.
t = 6 years
Therefore,.
A = 600(1 + 0.032/1)^1 × 6
A = 600(1.032)^6
A = £724.82
Answer:
-3
Step-by-step explanation:
-11b + 7 = 40
Subtract both sides by 7.
-11b = 33
Divide both sides by -11.
b = -3
Step-by-step explanation:
Variable x = total number of students enrolled
495 people at the dance - 7 teachers = 488 students
4/5 = 488/x
Step 1: cross multiply
4x = 2440
Step 2: isolate the variable (x) by dividing by 4
x = 2440 ÷ 4
Step 3: solve
x= 610 students total
Answer:
C) 50
Step-by-step explanation:
You first look at the 40 given to you. Then you know the angle opposite of it will be 40 also because of the law that opposite angles are the same. Once you have two angles in the triangle you can add 40 plus 90 in which you get 130 but that does not equal 180. So you can see that angle 1 is 50 because 50 and 130 equals 180.
B^2 - 4ac =
b=-5
a=-1
c=2
So then it equals =
(-5)^2 - 4(-1)(2)
-5^2 = Equals 25
the power of 2 is multiplying the same number it's powering. Two negatives = a positive. so 5x5 = 25.
4 x -1 x 2 = -8
4 x -1 = -4 and -4 x 2 = -8.
25 - (-8) = 33
