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)

Answers
Answer:
Exact answer = 26π/45 feet.
or we can write it as 1.815 feet to the nearest thousandth.
Step-by-step explanation:
The circumference of the circle = 2*4*π = 8π feet.
So the length of S = (26/360) * 8π

The volume of a cube is 8 in^3 What is the length of one side?
2.7in3
2 in3
2.7 in
2 in
Answers
Answer:
2 in
Step-by-step explanation:
Use the cube volume formula, V = s³, where s is the side length
Plug in 8 as V and solve for s:
V = s³
8 = s³
Take the cube root of both sides:
2 = s
So, the length of one side is 2 inches.
The length of one side of cube will be 2 in i.e. option D.
What is volume ?Volume is the amount of space that something contains or fills.
Volume of the cube = side³ = a³
We have,
Volume of the cube = 8 in³
And,
Side of cube = a
So,
Volume of the cube = side³ = a³
i.e.
8 = a³
⇒ a³ = 8
a = ∛8
On solving we get,
a = 2
i.e.
Side of cube = 2 in
Hence, we can say that the length of one side of cube will be 2 in i.e. option D.

Help me work out the equation of the line on this graph. I'll give out the brainiest!
Answers
Answer:
y=-1/4x+2
Step-by-step explanation:
The equation would be y=-1/4x+2 because the rise is -1 and the run is 4 (you could also say the run is -4 and the rise is 1. It doesn't really matter). The line also crosses the y axis at 2, which means that 2 is the y-intercept. :)
Answer:
y = (-1/4)x +2
Step-by-step explanation:
Having the actual graph is an easy way to calculate the equation of the line. Since the format is y = mx +b we just need to plug in numbers.
b = y-intercept
m = slope
We can automatically see that the y-intercept is 2, so b = 2. To find the slope we just calculate rise over run. The line is decreasing 1 unit for every 4 units it is "running". Therefore, -1/4 is your slope.
b = 2
m = -1/4
Now, all we need to do is plug in numbers.
y = (-1/4)x +2

First, you should find the area of the trapezoid which the formula for that is:
[tex](b1 + b2)h/2[/tex]
So, you will ad up 7in and 3in, and you should get 10in.
Now multiply 10 in by the height which is 5in, so it will be 50in^2. Then you have to divide that by 2 turning it into 25in^2.
For the top part, it is basically a triangle so you just multiply 3 by 6, giving you 18/2 = 9in^2

Answer:
y³+16y²+60y
Step-by-step explanation:
Complete question
Emma receives a large box in the mail. The box is 10cm longer than it wide, and the height is 6 cm more than the width. Find the polynomial function for volume of the box
Let the length be x
Let the width be y
let the height be z
If the box is 10cm longer than it wide, then x = y + 10
Also if the height is 6 cm more than the width,
z = y + 6
Volume of the box = xyz
Substitute
Volume of the box = (y+10)(y)(y+6)
Volume of the box = (y+10)(y²+6y)
Volume of the box = y³+6y²+10y²+60y
Volume of the box = y³+16y²+60y
Hence the required polynomial function is y³+16y²+60y

A painter is painting a rectangular wall that measures 23.6 ft by 19.2 ft. Each gallon can of paint covers 200 square feet. What are the fewest gallons needed to paint the wall?
Answers
Answer:
3 gallons
Step-by-step explanation:
Length of the rectangular wall = 23.6 feet
Width of the rectangular wall = 19.2 feet
Surface area of the wall = 23.6 × 19.2
= 453.12 square feet
∵ 200 square feet of the wall is covered by the amount of paint = 1 gallon
∴ 1 square feet of the wall will be covered by the amount of paint = [tex]\frac{1}{200}[/tex] gallons
∴ 453.12 square feet will require the amount of paint = [tex]\frac{453.12}{200}[/tex]
= 2.2656 gallons
Therefore, minimum 3 gallons will be required to paint the wall.
