According to the question
Given that ,
amount of saving of Myron is $1,698
amount of saving of Robert is $1,898
Toby has $100 less than Robert
amount of saving of Toby is $100 less than Robert
Robert has $1,898

Savings account is a basic account type that lets you deposit money safely with a bank. It ensures safety and access to your money whenever you need. You can withdraw your funds, either digitally or in person, at any point in time.
Having a savings account is a liquid investment, so you have the ease of using your funds any time for transactions. A savings account also earns decent returns;
A savings account is like a virtual locker that safeguards your money and pays a certain amount of interest. As opposed to a fixed deposit (FD), you can use the money in your savings account whenever you need. A savings account also has other uses.
With your savings bank account, you make transactions, receive payments, pay your credit bills, and make investments. You can also pay for utilities such as electricity bills, ration, mobile phone recharges, and shopping. A savings account safeguards your money from theft and misplacement and reduces the stress that comes with carrying too much cash.
how to calculate saving
If the daily amount is Rs 3 lakhs and the interest rate on the savings account is 4% per year, the computation will be Interest on a monthly basis = Daily Balance * (Number of days) *Interest / (Days in the year)3 lakhs * 30 * (4/100) / 365 = Rs 986 per month in interest Daily
balance: 3 lakh
Number of days: 30
Interest: 4%
Days in the year: 365
According to Bank, "Savings bank interest will be calculated on the daily balances maintained in your account. Savings Bank interest will be paid at quarterly intervals."

The endpoints of CD are C (1, -6) and D (7, 5). Find the coordinates of the midpoint M by using the Midpoint Formula.
the mid point of the points C and D is M = ( 4 , - 1 / 2 ).
We are given the coordinates of the point:
C ( 1 , - 6 )
D ( 7 , 5 )
We need to find the mid point M for it.
Here, we have:
x₁ = 1
x₂ = 7

Each pair of values is from an inverse variation. Find the missing value. (2,5),(4, y)
The missing value of inverse variation is 2.5
What is Inverse variation ?The inverse variation property states that , whenever the product of values of two quantities is a constant value then there is opposite variation between these two corresponding values. Or we can also say that if the productive nature of two corresponding values is constant, then one quantity is inversely varies with second quantity.

In the given question,
Take the order pair (2,5)
As it is an inverse variation, we can substitute it

In 1992, the moose population in a park was measured to be 3590. By 1999, the population was measured again to be 4500. If the population continues to change linearly
A.) Find a formula for the moose population, P, in terms of t, the years since 1990.
P(t)= ____
B.) What does your model predict the moose population to be in 2006?
Answer:
A.) P(t) = 130t +3330
B.) P(16) = 5410
Step-by-step explanation:
Given the ordered pairs (t, P(t)) = (2, 3590) and (9, 4500), you want a linear model that describes the relation. You also want the value of P(16).
A.) Linear modelWe can write the formula for P(t) starting with the point-slope equation for P in terms of t. To do that, we need the slope:
m = (P2 -P1)/(t2 -t1)
m = (4500 -3590)/(9 -2) = 910/7 = 130
The point-slope equation will be ...
P -P1 = m(t -t1)
P -3590 = 130(t -2)
Solving for P, we find ...
P = 130t -260 +3590 . . . . . eliminate parentheses, add 3590
P(t) = 130t +3330
B.) PredictionThe value of P(16) will be ...
P(16) = 130(16) +3330 = 2080 +3330 = 5410
The moose population is predicted to be 5410 in 2006.
__
Additional comment
The value of t is years since 1990, so the relevant values are ...
1992: t = 1992 -1990 = 2
1999: t = 1999 -1990 = 9
2006: t = 2006 -1990 = 16
Values of moose population by linear model A.) P(t) = 130t +3330 B.) P(16) = 5410
What does the term "linear model" mean?
In a linear model, the terms are added rather than multiplied, divided, or provided as a non-algebraic function, as has been the case thus far in this section. A linear model is not just a straight line or its higher dimensional equivalent.Given the ordered pairs (t, P(t)) = (2, 3590) and (9, 4500), you want a linear model that describes the relation. You also want the value of P(16).
A.) Linear model
We can write the formula for P(t) starting with the point-slope equation for P in terms of t. To do that, we need the slope:
m = (P2 -P1)/(t2 -t1)
m = (4500 -3590)/(9 -2) = 910/7 = 130
The point-slope equation will be
P -P1 = m(t -t1)
P -3590 = 130(t -2)
Solving for P, we find
P = 130t -260 +3590 . . . . . eliminate parentheses, add 3590
P(t) = 130t +3330
B.) Prediction
The value of P(16) will be
P(16) = 130(16) +3330 = 2080 +3330 = 5410
The moose population is predicted to be 5410 in 2006.
(B) The value of t is years since 1990, so the relevant values are
1992: t = 1992 -1990 = 2
1999: t = 1999 -1990 = 9
2006: t = 2006 -1990 = 16

the magical coin that doubles every day.
will the value of the magical coin exceed to a million dollars within 28 days? explain or show your reasoning.
yes, if the value of the coin is 1 dollar, then it will exceed the million dollars within 28 days.
Will the value of the magical coin exceed to a million dollars within 28 days?
It will depend on the original value of the coin, value that we don't know, so I will assume that the value of the coin is $1.
If this coin doubles each day, then the day zero its value is $1.
After one day its value is 2*$1 = $2
After another day its value is 2*$2 = $4
And so on, this is modeled by the exponential equation:
y = $1*(2)^x
Where y is the total value and x is the number of days.
After 28 days (this means we use x = 28) the value will be:
y = $1*(2)^28 = $268,435,456
That is a lot more than one million dollars.

An unit rate is a ratio that is used for comparing two different kinds of quantities which have different units.
It is given that Jim has made $238 after working for 17 hours.
If we try to find out the unit rate that how much he earn in 1 hour then it can be find out by dividing money earned by no. of hours he has worked.
So , the in 1 hour Jim will make money :
= 238 / 17

a. The slope of a line that is parallel to y = 3/5x + 7 is: 3/5.
b. The slope of a line that is perpendicular to y = 3/5x + 7 is: -5/3.
How to Determine the Slope of Parallel Lines?Given a line is represented by the equation, y = 3/5x + 7, the slope (m) of the line is 3/5.
Any line that is parallel to y = 3/5x + 7 will have a slope (m) = 3/5 [same slope value].
On the other hand, any line that is perpendicular to y = 3/5x + 7 will have a slope of -5/3 [negative reciprocal].
Therefore:
a. The slope of a line that is parallel to y = 3/5x + 7 would be: 3/5.

Using substitution method, solve
3x-y=0
2x+y=5
Answer:
x=1 y=3
Step-by-step explanation:
Hello!
So, this says to use the substitution method. The substitution method is where you set one equation equal to one of the letters, and then put that whole equation in the other equation.
So->
3x-y=0
if we move the y to the other side we have:
3x=y
then we have our second equation:
2x+y=5
Now, we don't know what NUMBER y is yet, but we do know that it is equal to 3x. Thus, we can put it into the equation like this.
2x+(3x)=5
Then, we can add like terms and get:
5x=5
Dividing each term by five, we get
x=1
We could have also done this be solving for x in the equations and then substituting that in instead of y.
Now that we have x, we can easily put it into the equations and solve for y.
3x-y=0
3(1)-y=0
3=y
So now we know that x is equal to 1 and y is equal to 3.
