Answer: 4.5
Step-by-step explanation:
A half is 0.5 as a decimal. So:
4 + 0.5 = 4.5
Answer:10
Step-by-step explanation:
if a song costs $1.50 and a video is 2 times that amount of a song, then the video would cost $3. you have a balance of $60. you by 15 videos to start. i multiplied $3 by 15 to get the cost of the movies, witch is $45. after i got the cost of the movies i subtracted the $45 from the over all amount, i got 15. now to the songs. i have $15 to get music. 2 songs costs $3( 1.50+1.50= 3.00). 4 songs would cost $6. 8 songs would cost $12. after that i just added 1.50 until i hit a total of 15. so you can get 10 songs for $15

Answer: The cost of 97.5 square feet of glass is $1828.13
( Incredible! Who has a window that size in their house?!?! )
Step-by-step explanation:
The Area (not perimeter) is 1/2 b*h
To find the height if this equilateral triangle we can use the Pythagorean Theorem c² = a² + b²
The side of the triangle is 15; that is the hypotenuse, c
The <u>b</u>ase of the right triangle we need is 7.5
The <u>a</u>ltitude (height) is what we need to calculate.
15² = a² + 7.5²
225 = a² + 56.25 Subtract 56.25 from both sides, then take the square root to find <u>a, that is h in the Area equation.</u>
√168.25 = 12.99 . Round to 13
Calculate the Area = 1/2 b*h
15*13/2 = 97.5 square feet.
Multiply by the cost per square foot: $18.75
97.5 * 18.75 = 1828.125 . Round to $1828.13
