Answer:
the download cost for a song is $1 and $11 for a movie
Step-by-step explanation:
According to the questions, the following equations are as follows:
Let us assume the song be x
And, the movies be y
So,
20x + 13y = $163.........(i)
13x + 13y = $156........(ii)
Now solve substract second equation from the first equation
7x = $7
x = $1
And the y value is
20 + 13y = $163
13y = $163 - $20
13y = $143
y = $11
Hence, the download cost for a song is $1 and $11 for a movie
Your answer would be 91.1 units².
We can split this shape into a trapezium and a semicircle, and then find the area of both and add them.
To find the area of a trapezium, the formula is
(a + b)/2 × h, which means we do 14 (the length of AD) + 8 (the length of BC) = 22, and 22/2 = 11. Then we multiply 11 by the height of the trapezium, which is 6 because 10 - 4 = 6. This gives us the area of the trapezium as 66 units².
To find the area of a semicircle, the formula is πr²/2, and the radius is 4 because the diameter is 8 (16 - 8 = 8). This means we do π4²/2 = 16π\2 = 8π = 25.13.
Then we need to add together 66 and 25.13, which equals 91.13, or 91.1 to the nearest tenth.
I hope this helps!
I think that a linear equation can have no solution, one solution, or infinitely solutions. It just depends on what is the equation. That's what I think
Answer:
<h3>
y = -3x</h3>
Step-by-step explanation:
The standard expression of equation of a line in slope-intercept form is expressed as;
y = mx+c
m is the slope
c is the intercept
Given
slope m = -3
Point (x, y) = (-1, 3)
x = -1 and y = 3
Get the intercept
To get the intercept c, we will substitute the given values into the equation above to have;
y = mx+c
3 = -3(-1)+c
3 = 3 + c
c = 3-3
c = 0
Substitute m = -3 and c = 0 into the equation above;
y = mx+c
y = -3x+0
y = -3x
Hence the required linear equation is y = -3x

Find Sales Price of 5 gallons of ice-cream:
---------------------------------------------------------------------
Sales price of Fruity Tooty = $6.00
Sales price of Peanut Butter = $5 x 2 = $10.00
Sales price of Rocky Road = $5.25 x 2 = $10.50
Total Sales Per 5 gallon = $6 + $10 + $10.50 = $26.50
---------------------------------------------------------------------
Find Variable Cost of 5 gallons of ice-cream:
---------------------------------------------------------------------
Variable Cost of Fruit Tooty = $5.25
Variable Cost of Peanut Butter = $4.50 x 2 = $9.00
Variable Cost of Rocky Road = $4 x 2 = $8.00
Total Variable Coast = $5.25 + $9 + $8 = $22.25
---------------------------------------------------------------------
Fixed Cost Given:
---------------------------------------------------------------------
Fixed Cost = $7500
---------------------------------------------------------------------
Define x:
---------------------------------------------------------------------
Let x be the number of 5 gallons that need to be sold to breakeven:
---------------------------------------------------------------------
Find x:
---------------------------------------------------------------------
26.50x = 7500 + 22.25x
26.50x - 22.25x = 7500
4.25x = 7500
x = 7500 ÷ 4.25
x = 1764.7 (Nearest tenth)
---------------------------------------------------------------------
Find the number of gallons of ice-cream needed:
---------------------------------------------------------------------
Total number of 5 gallons needed = 1764.7
Total gallons needed = 1764.7 x 5 =8823.5
---------------------------------------------------------------------
Answer: I sceam needs to sell 8823.5 gallons of ice cream to break even.
