Step-by-step explanation:
Given,
x = 81° and y = 41°
Also given in the figure that,
m∠AOB = x + y
Therefore, value of m∠AOB,
m∠AOB = x + y
= 81° + 41°
= <u>122° (Ans)</u>
Answer:
∠ABC is a right angle

Answer:
the value of the investment after 3 years= £11,904
Step-by-step explanation:
sarah invests £9600 at a simple interest rate of 8% per year
number of years = 3
Formula for simple interest
I = P*n* r
P is the initial amount invested= 9600
r is the rate of interest = 8% = 0.08
n = number of years = 3
Now we find interest using formula
I = 9600 * 0.08 * 3= 2304
Interest amount is 2,304
Now we add the interest with the initial amount to get the value of investment after 3 years
9600 + 2304= 11904
Answer:
y=40.5
Step-by-step explanation:
you need to get y out of a fraction, to do so multiply by the denominator on both sides
3(2/3y) = 3(27)
then divide to solve for y
2y = 81
y=40.5
Answer:
43.35
