In linear equation, $56.65are the value of the coins in dollars .
What is a linear equation example?
Ax+By=C is the usual form for two-variable linear equations.As an illustration, the conventional form of the linear equation 2x+3y=5 When an equation is given in this format, finding both intercepts is rather simple (x and y).A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.The variables in the previous sentence, y and x, are referred to as a "linear equation with two variables" at times.We need to find how many of the 206 coins are nickels, dimes, or quarters.
We know the quantities of each coin in relation to one another.
From that relationship we can set up a ratio.
Let Q = number of quarters
Let D = number of dimes
Let N = number of nickels
Then Q:D:N = 1:1:2
this tells us if the girl had 4 coins, she would have 1 quarter, 1 dime, and 2 nickels.
We want to keep this same ratio but we want the total number of coins to be 206.
If we divide 206 by 4, we get the number that we use to multiply our ratio.
206/4 = 51.5
So she has 51.5 quarters, 51.5 dimes, and 103 nickels.
the value of the coins in dollars = 51.5(0.10) + 51.5(0.05) + 103(.25) = $56.65

Step-by-step explanation:
Landon works at a movie theater. yesterday he worked 4 hours and made $48. how much money will he make in 1 hour? how many hours does he need to work to make $156?
The amount of money Landon will make in 1 hour is $12 and he needs to work for 13 hours to make $156.
The amount of money he will make in 1 hour can be calculated by using division.
It can be determined by dividing the total amount earned by him by the total number of hours he worked yesterday. Therefore;
money earned in 1 hour = total amount earned ÷ total number of hours
money earned in 1 hour = 48 ÷ 4
money earned in 1 hour = $12
Now we can calculate the number of hours he needs to work at the movie theater to make $156 by dividing the desired amount by the amount earned in one hour. Therefore;
number of hours required = 156 / 12
number of hours required = 13
Hence, Landon will make $12 in one hour and he will need to work 13 hours to make $156

in a G.P the 7th term is 16 times the 3rd term and the sum of the 2nd term and the 6th term is 102.if the common ratio(r) is positive .find the
1 common ratio
2 first term
3 sum of the 8th term
1. Common ratio of the G.P is 50
2. First term of the G.P is -100
3. Sum of the 8th term is 250.
Given,
In a Geometric progression,
7th term is 16 times the 3rd term
Sum of 2nd and 6th term is 102
Common ratio is positive.
Now,
Take a as first term.
r as common ratio
Then,
2nd term = a + r
6th term = a + 5r
So,
a + r + a + 5r = 102
Then,
2a + 6r = 102
2a = 102 - 6r
a = (102 - 6r) / 2
Now,
1. Common ratio:
Consider any term,
Here, 3rd term = a + 2r
Substitute a here.
a + 2r = (102 - 6r) / 2 + 2r
102 - 6r + 4r = 2
102 - 2 = 6r - 4r
100 = 2r
r = 100/2 = 50
That is,
The common ratio of the G.P is 50.
2. First term:
Consider,
7th term is 16 times the 3rd term
That is,
3rd term = a + 2r
7th term = 16(a + 2r)
r = 50
Then,
a + 50 × 2 = 16(a + 50 × 2)
a + 100 = 16(a + 100)
a + 100 = 16a + 1600
100 - 1600 = 16a - a
15a = -1500
a = -1500/15
a = -100
Therefore,
The first term of the G.P is -100
3. Sum of the 8th term.
8th term = a + 7r = -100 + 7 × 50 = -100 + 350 = 250
That is,
The sum of the 8th term is 250.

Four friends on a ski trip pay $210 each to share the rent of a cabin. The cost per person varies inversely
the number of persons. How many people sharing the rent would make the cost $120 per person?
Seven people sharing the rent would make the cost $120 per person.
What is Inversely Proportional?When two quantities are inversely proportional, that is, when an increase in one causes a decrease in the other and vice versa, they are said to be inversely proportional.
The general equation for inverse variation is y = k/x, where k is the proportionality constant and x and y are two variables.
Given:
The price paid by Four friends on a ski trip to share the rent of a cabin = $210
The cost per person varies inversely with the number of persons.
Let the cost be C and the number of persons be n,
C ∝ 1/n
So, the equation becomes, k = Cn.
Putting the values in the equation we obtain the value of k,
k = 210×4 = 840
We have to find the number of people sharing the rent that would make the cost $120 per person.
Using the equation,
k = Cn
840 = 120 × n
n = 840/120 = 7
Therefore, seven people sharing the rent would make the cost $120 per person.

Approximate −12 + the square root of thirty-two to the nearest tenth
The approximate value of the expression given will be equal to -6.3.
An approximation may be defined bringing the value of a certain entity which is almost similar, but not exactly equal to the correct value. The expression can be written as −12 + √32. The value of √32 can be written as 5.656. Since, after decimal 6 to the right of 5 is greater than 5 so to the nearest tenth, we can write as 5.66. Therefore, √32 = 5.66
For the required value of the expression we can write,
−12 + √32
Putting the value of √32 = 5.66 in the expression we get
-12 + √32 = -12 + 5.66
After solving we get

So 1 mile = (15/8)/(3/2) = (15*2)/(8*3) = 30/24 = 5/4
so , the unite rate is 5/4 inches per mile .
given the road B is 15 miles long .
