800+16x=720+21x
80+16x=21x
80=5x
X=16
So 16 hours :)
Answer:
Step-by-step explanation:
take 45 degree as reference angle
use sin rule
sin 45=opposite/hypotenuse
1/=x/2
do cross multiplication
x= *
x=2
x=2/
x=
pythagoras theorem
a^2+b^2=c^2
( )^2+y^2=(2 )^2
2+y^2=8
y^2=8-2
y=
The value of x is 5. Thus, the correct statement is:
x = 5 is a true solution because log subscript 2 Baseline (16) = 4
<h3>Data obtained from the question </h3>
- Log₂ (x + 11) = 4
- Value of x =?
<h3>How to determine the value of x </h3>
Log₂ (x + 11) = 4
x + 11 = 2⁴
x + 11 = 16
Collect like terms
x = 16 – 11
x = 5
<h3>**Check** </h3>
Log₂ (x + 11) = 4
x = 5
Log₂ (5 + 11) = 4
Log₂ 16 = 4
Find the value of Log₂ 16
Log₂ 16 = n
16 = 2ⁿ
2⁴ = 2ⁿ
n = 4
Thus,
Log₂ 16 = 4
Therefore, the correct answer to the question is:
x = 5 is a true solution because log subscript 2 Baseline (16) = 4
Complete question
Which of the following is true regarding the solution to the logarithmic equation below? log Subscript 2 Baseline (x + 11) = 4. x + 11 = 2 Superscript 4. x + 11 = 16. x = 5. x = 5 is not a true solution because log Subscript 5 Baseline (16) not-equals 2 x = 5 is not a true solution because log Subscript 5 Baseline (16) not-equals 4 x = 5 is a true solution because log Subscript 2 Baseline (16) = 4 x = 5 is a true solution because log Subscript 4 Baseline (16) = 2

The employer's contribution is the total cost of the plan minus what Melissa pays, which can be found by subtracting Melissa's contribution from the total cost of the plan.
So, the employer's monthly contribution to the total cost of the plan is $475-$85=$390.
Therefore, over the course of one year, the employer would contribute $390*12=$4680.
