Sum of interior angles of any triangle is 180
so:
x + (3x+25) + (x -5) = 180
5x + 20 =180 5x =160
x = 32
∠G = 3x + 25 = 121
Answers:
After 7 years the car is worth $10,196(,46)
Explanation:
Year 1: $24,950•0,88=21,956
Year 2: $21,956•0,88=19,321(,28)
Year 3: $19,321(,28) •0,88=17,002(,73)
Year 4: $17,002(,73) •0,88=14,962(,40)
Year 5: $14,962(,40) •0,88=13,166(,91)
Year 6: $13,166(,91) •0,88=11,586(,88)
Year 7: $11,586(,88) •0,88=10,196(,46)
Answer:
k > 12
Step-by-step explanation:
If a quadratic equation has no real roots the values of b^2 - 4ac
( for the general form ax^2 + bx + c = 0) is negative,
So we have the inequality:
(-12)^2 - 4*3* k < 0
144 - 12k < 0
12k > 144
k > 12
So cost=50+75t
so 200=50+75t
subtract 50 from both sides
150=75t
divide both sides by 75
2=t
$200=2 hours
50+75t=cost
300=50+75t
subtract 50 from both sides
250=75t
divide both sides by 75
10/3=t=200 mins=3hours 20 mins=$300
