Answer:
Y ≈ 59.0°
Step-by-step explanation:
Using the Cosine rule
cosY = 
with x = 22, y = 20, z = 18
cosY = 
= 
= 
, then
Y = 
( ) ≈ 59.0° ( to the nearest tenth )
First off, notice that this is a right triangle.
You can use this to help write equation.
Equation : x+ (4x-85)=90. The correct answer is "c"
Answer:
11235.35
Step-by-step explanation:
Given data
P=8225
R=4.2%=0.042
T=8years
The simple interest formula is
A=P(1+rt)
Substitute
A=8225(1+0.042*8)
A=8225(1+0.336)
A=8225*1.366
A=11235.35
Hence the balance will be 11235.35
The value of the investment in 5 years is $5805.9
<h3>What is Interest ?</h3>
Interest is the amount earned over years for the amount invested.
It is given that
Principal = $5000
Rate = 3%
Compounded Quarterly
Time = 5 years
Amount = ?
The Amount is given by the formula
Amount = P( 1 + (r/n))ⁿˣ
Here n = t = time period for which the investment has been done.
Amount = 5000( 1+(3/4 * 100)⁴ˣ⁵
Amount = 5000 (1.16)
Amount = $ 5805.9
Therefore , The value of the investment in 5 years is $5805.9
