Arianna has an extensive music DVD collection. She owns 2300 DVD in total. Twenty percent of the DVD's are country music. How many country music DVDs does she own?
Answers
Answer: 460 dvds
Step-by-step explanation:
Since the total is 2300 dvds and 20% (0.2) is country music. You can do 2300 x 0.2. You will get 460 dvds.

Answers
Answer:
√29
Step-by-step explanation:
We are here given that ,
- a - b = 3
- ab = 5 .
Now square the first equation ,
⇒ a - b = 3
⇒ ( a - b)² = 3²
⇒ a² + b² - 2ab = 9
⇒ a² + b² - 2(5) = 9
⇒ a² + b² -10 = 9
⇒ a² + b² = 9 + 10
⇒ a² + b² = 19
- Adding 2ab both sides ,
⇒ a² + b² + 2ab = 19 + 2(5)
⇒ (a + b)² = 19 + 10
⇒ ( a + b)² = 29
⇒a+b=√29.

Answer:
U (1, 16 )
Step-by-step explanation:
given endpoints (x₁, y₁ ) and (x₂, y₂ ), then the midpoint M is
M = ( ,
) ← midpoint formula
let (x₁, x₂ ) = U (x, y ) and (x₂, y₂ ) = V (13, 8 )
substitute these values into the midpoint formula and equate to the corresponding coordinates of M (7, 12 )
= 7 ( multiply both sides by 2 )
x + 13 = 2 × 7 = 14 ( subtract 13 from both sides )
x = 1
and
= 12 ( multiply both sides by 2 )
y + 8 = 2 × 12 = 24 ( subtract 8 from both sides )
y = 16
coordinates of U = (1, 16 )
2y + 4x = 2
