Answer:
7
Step-by-step explanation:
→ Find the scale factor
30 ÷ 25 = 1.2
→ Multiply answer by 20
20 × 1.2 = 24
→ Equate equation to 24
4x - 4 = 24
→ Add 4 to both sides
4x = 28
→ Divide both sides by 4
x = 7
Distance ÷ Speed = Time
81 miles ÷ 60.4 miles per hour= 1.34 hours
1.34 hours ≈ 1 hour 20 min
Answer:
2x + 10
Step-by-step explanation:
-3x+5(x+2) = -3x+5x+10 = 2x + 10
Answer:
49 x^4 - 4 = 0
(7 x^2 - 2) (7 x^2 + 2) = 0
Only the first term will have real roots
7 x^2 = 2
x = (2 / 7)^1/2 = .535 or -.535
Answer:
0.019%
Step-by-step explanation:
The probability of making a free throw is 82%, so the probability of not making it is 18%. The probability of not making 5 free throws is:
P = (0.18)^5
P ≈ 0.00019
