Answer:
1. 23.0 cm
2. 21.0 ft
3. 31.0 yd
Step-by-step explanation:
1. 30/sin110 = RT/sin46
RT = sin46 × 30/sin110
RT = 22.96516279
2. Angle A = 180 - 61 - 53 = 66°
24/sin66 = AB/sin53
AB = sin53 × 24/sin66
AB = 20.98116966
3. 18/sin28 = HP/sin54
HP = sin54 × 18/sin28
HP = 31.01850475
Answer:
$3000.
Step-by-step explanation:
Suppose the amount invested at 7% is $X and the amount invested at 10% is $Y (assuming that the college student invested all his/her income on the two schemes). Therefore:
X + Y = 8200 (The sum of investments is basically the total income).
0.07X + 0.1Y = 664 (The sum of the interest received from the invested amounts is actually the total return).
Now solving these 2 simultaneous equations:
x + y = 8200 (Equation 1)
7x + 10y = 66400 (Equation 2)
From (Equation 1):
x = 8200 - y (Equation 3)
Put (Equation 3) in (Equation 2):
7(8200 - y) + 10y = 66400.
57400 - 7y + 10y = 66400.
3y = 9000
y = 3000.
$Y is the amount invested at 10%, therefore the final answer is $3000!!!
Answer:
Step-by-step explanation:
The correct solution of the given equation is as follows :
We have,
⇒ 
⇒ 
⇒ 
Comparing the power of equal base, we get
- 6 = 8a
⇒ 
⇒
Therefore, before equating the powers of two terms the base of the terms should be equal and here this is the error. (Answer)
