Jonathan Martinez has $85 deducted from his monthly pay for his group health insurance. His employer
pays 60% of the cost. What is the annual premium amount for Jonathan's group health insurance?
If his employer pays 60% of the cost. The annual premium amount for Jonathan's group health insurance is $2,550.
What is annual premium amount ?Annual premium can simply be defined as the premium a person is expected to pay per year or annually.
First step is to find the cost
Cost = $85/ (1-.60)
Cost = $85/.40
Cost = $212.5
Now let find the annual premium amount
Annual premium amount = Cost × 12 months
Annual premium amount = $212.5 × 12 months
Annual premium amount = $2,550
Therefore the annual premium amount is the amount of $2,550.

Find the interest rate for a $6000 deposit accumulating to $6957, compounded annually for 6 years.
The interest rate for a $6000 deposit accumulating to $6957, compounded annually for 6 years is r=2.49%.
What is meant by interest rate?The interest rate is the amount charged by the lender to the borrower over and above the principal amount. In terms of the receiver, a person who deposits money in any bank or financial institution obtains additional revenue due to the time value of money, which is referred to as interest received by the depositor.
Here's a simple interest formula: Interest = P x R x T, P = Principal Amount (the beginning balance).
Given, Amount=6957, P=6000, t=6 years
A=P[tex](1+(r/n)^{nt}[/tex]
6957=6000(1+(r/1))[tex](1+(r/1))^{6}[/tex]
[tex](1+(r/1))^{6}[/tex]=6957/6000
=1.1595
ln[tex](1+(r/1))^{6}[/tex]=ln(1.1595)
6(1+(r/1))=ln(1.1595)
(1+(r/1))=ln(1.1595)/6=0.0246
(1+(r/1))=[tex]e^{0.0246}[/tex]
1+r=1.02490508
r=0.02490508
r=2.49%
The interest rate for a $6000 deposit accumulating to $6957, compounded annually for 6 years is r=2.49%.

You’re planning to visit with 7 clients today and you estimate that at most each client will require 3/4 hours of your time. At most, how long does your estimate say it will take you to visit with all of these clients?
Mathematically, it will take you 315 minutes (5 hours, 15 minutes) at most to visit with all 7 clients.
How is the time determined?We can employ mathematical operations, including addition, subtraction, division, and multiplication to determine the total time required to visit the seven clients.
Since we know that a client requires 3/4 hours or 45 minutes of your visiting time, we can multiply 45 minutes by 7.
The product of the multiplication operation gives 315 minutes, which we can convert into hours and minutes by a division operation.
The number of clients visiting today = 7
The time it a client requires of your visit time = 3/4 hours
3/4 hours = 45 minutes (0.75 x 60)
For the 7 clients, it will take you 315 minutes (45 x 7)
315 minutes equal 5 hours and 15 minutes.
Thus, using basic mathematical operations, we can conclude that, at most, you require 5 hours and 15 minutes to attend to all seven clients today.

√(2) rational or irrational
Answer:
√2 is irrational.
Step-by-step explanation:
√2 = p/q, where 'p' and 'q' are integers, q ≠ 0 and p, q have no common factors (except 1). Thus, p and q have a common factor 2. This statement contradicts that 'p' and 'q' have no common factors (except 1). We can say that √2 is not a rational number.

A taxi company charges $4 as soon as a passenger enters the cab, then $3/mile for the first 6 miles, and then $2/mile for the distances greater than 6 miles. What best models the taxi company’s charges?
The total charge /cost c of taxi company's for a trip of d miles will be
c = 0.6 d + 1.2
What is mile with example?
A mile (mi) is a customary unit of distance. It is generally used to express the distance between cities, roads, and the length of rivers.For example , one could say the distance of a marathon race is about 26.3 miles or 26.3 mi.Let c be the cost/charges and d be the miles.
Let $3/mile be the basic charge as well as the cost for the distance covered.
For 6 mile trip , the cost is $ 4.80 , then the cost of 3 miles is
$ 4.80 - $ 3.00 = $ 1.80
Therefore, the cost for 1 mile is $ 1.80 / 3 = $ 0.60
The basic fee for hiring the cab is $ 3.00 - $ 1.80 = $ 1.20.
Therefore the total charge /cost c of taxi company's for a trip of d miles will be
Total cost = cost for 1 mile + basic fee for hiring the cab
c = 0.6 d + 1.2
If the formula is correct we get the given cost :
For 3 miles , then the cost c = 0.6(3) + 1.2 = $ 3.00
For 6 miles , then the cost c = 0.6(6) + 1.2 = $ 4.80

Function A is represented by the equation y=2 x+5
Function B is a linear function that goes through the points shown in the table.
Which statement correctly compares the rates of change of the two functions?
Answer:
The rate of change is the same for both A and B (2)
Step-by-step explanation:
In the equation, the rate of change is shown as the coefficient of the variable x. That is the number before the x which is 2.
In the table you find the rate of change as the change in y over the change in x. In the table the y's are increasing by 4 (3- -1), 2 (5-3) and 4 (9-5). The x's are increasing by 2 (3-1), 1 (4-3) and 2 (6-4).
If I take the change in y over the change in x, I will get 4/2 = 2, 2/1 = 2 or 4/2 = 2
From the table the rate of change is also 2.

The sum of two numbers is always greater than the larger of the two numbers?
False
Step-by-step explanation:The sum is the total of an addition problem.
Addition of Positive Numbers
Most commonly, people add together positive numbers. Positive numbers are numbers greater than 0. The sum of 2 positive numbers is always greater than the addends. For example:
2 + 3 = 5The sum of these positive numbers, 5, is greater than the larger number, 3. However, the addition of positive numbers is not the only way to add.
Addition of Negative Numbers
Negative numbers are numbers less than 0. If you add negative numbers, then the sum will be less than the addends. So, the statement above is not true. For example:
-2 + 3 = 1In this case, the sum, 1, is less than the larger number, 3. This disproves the statement given.

How to find the height of the tower?David is standing 500 feet away from the base of a cell phone tower.
The angle of elevation from his eyes to the top of the tower is 78°. David eyes are 6 feet above the ground . The height of the tower can be found as follows:
This situation forms a right angle triangle. Therefore,
using trigonometric ratios,
tan 78° = opposite / adjacent
tan 78° = x / 500
cross multiply
x = 500 tan 78°
x = 500 × 4.70463010948
x = 2352.31505474
