Answer:
c = 1.29s + 2
Step-by-step explanation:
c represents the total cost
s represents the number of songs downloaded
1.29 represents the cost charged for every song downloaded
2 represents the initial cost to download the app
1.) 2=50%
2.) 25% of 30,000= 7500
Answer:
x = 50 in
Step-by-step explanation:
Since it is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2
14^2 + 48^2 = x^2
196 + 2304 = x^2
2500 = x^2
Take the square root of each side
sqrt(2500) = sqrt(x^2)
50 =x
x = 50 in
Answer:
The equation that can be used to find the width is 2(13 + w) = 42
The width of the rectangle is 8 inches
Step-by-step explanation:
The formula of the perimeter of a rectangle is P = 2(l + w), where l is its length and w is its width
∵ One rectangle has a length of 13 inches
∴ l = 13 inches
∵ Its perimeter is 42 inches
∴ P = 42 inches
- Substitute the values of l and P in the formula of the perimeter
∵ 42 = 2(13 + w)
The equation that can be used to find the width is 2(13 + w) = 42
To find W divide both sides by 2
∴ 21 = 13 + w
- Subtract 13 from both sides
∴ 8 = w
The width of the rectangle is 8 inches
