Angel has xx dimes and yy nickels. He has at most 13 coins worth no less than $0.95 combined. Solve this system of inequalities graphically and determine one possible solution.
Answers
Answer:
a possible solution is (10,1)
Step-by-step explanation:
Here, we want to solve the given inequality and determine one possible solution
From the question, we have it that;
x + y ≤ 13
Mathematically, we have it that 1 dime is worth $0.1
A nickel is worth $0.05
0.1x + 0.05y ≥ 0.95
please check the attachment for the graph of both equations
The point of intersection represents the solution.
we have a point here as (10,1)

Juan has 240 marbles. This is three times as many marbles as Jon and Jeremy have combined. If Jon has 50 marbles, how many marbles does Jeremy have?
Answers
Answer:
30
Step-by-step explanation:
Let x = number of marbles Jon has
y = number of marbles Jeremy have
3(X + Y) = 240
3(50 + Y) = 240
Divide both sides by 3
50 + Y = 80
Solve for y
Y = 30

Step-by-step explanation:
The total degrees of the interior angels of a six sided ploygon is 720, so all you need to do is add the shown angles together and subtract that number from 720:
130 + 130 + 130+ 100 + 100 = 590
720 - 590 = 130

Elias had 3 time as much money as munah.Elias spent $240 and munah received $60 from her brother. In the end.Elias and munah had the same amount of money.How much did elias have at first
Answers
Answer:
$450
Step-by-step explanation:
let m represent the amount of money munah has
That means elias would have 3 * m or 3m dollars.
Then, you have m + 60 = 3m - 240
solve:
[tex]m + 60 = 3m -240\\300 = 2m\\m = 150[/tex]
So munah started with $150. Since elias has 3 times as much, they have 150 * 3 = 450

A hiking trail rises 6 feet for every horizontal change of 100 feet. What is the slope of the hiking trail?
Answers
Given:
A hiking trail rises 6 feet for every horizontal change of 100 feet.
To find:
The slope of the hiking trail.
Solution:
We have,
Rise = 6 ft
Run = 100 ft
We know that
[tex]Slope=\dfrac{Rise}{Run}[/tex]
[tex]Slope=\dfrac{6}{100}[/tex]
[tex]Slope=0.06[/tex]
Therefore, the slope of the hiking trail is 0.06.
The slope of the hiking trail is equal to 0.06.
Given the following data:
Vertical distance (rise) = 6 feetHorizontal distance (running) = 100 feetTo find the slope of the hiking trail, we would use the following formula:
Slope is the ratio of the vertical distance measured to the horizontal distance measured.
Mathematically, the slope of a hiking trail is given by the formula:
[tex]Slope = \frac{Rise}{Running}[/tex]
Where:
V is the rising vertical distance of an object.H is the horizontal distance an object runs through.Substituting the given parameters into the formula, we have;
[tex]Slope = \frac{6}{100}[/tex]
Slope = 0.06

In a regular polygon each interior angle is 140° greater than each exterior angle. Calculate the number of sides of the polygon
Answers
Answer:
18 sides.
Step-by-step explanation:
The interior and exterior angles sum to 180 so:
I + E = 180
also I - E = 140 (given)
So, adding to eliminate E:
2I = 320
I = 160 degrees and the external angle E = 1809 - 160 = 20 degrees.
Since the sum of all exterior angles in a polygon = 360 degrees
- the number of sides = 360 / 20 = 18.
