Answer:
63 m
Step-by-step explanation:
We know the rate in 45 m / min
We need to change the time to min
1 min 24 sec
We know that 1 min = 60 sec so 24 seconds is 24/60 ths of a minute
1 min 24/60 min
1 2/5 min
Changing to decimal form
1.4 minutes
Now we multiply by the rate to get the distance
d = r *t
d = 45 m/ min * 1.4 min
d= 63 m
Well i do say that it has to be greater than 0
Bob's Bikes
260 × 0.2 = 52
260 - 52 = 208
208 × 2 = $416.00
Walt's Wheels
300 × 0.6 = 180
300 - 180 = 120
120 × 2 = $240.00
Carson's Cycles
310 × 0.1 = 31
310 - 31 = 279
279 × 2 = $558.00
(i can't read what it says for $50, comment below if it makes a difference, i'll edit)
Tino's Transportation
260 ÷ 2 = 130
260 + 130 = $390.00
B) Walt's Wheels provides the lowest price for two bicycles.
Answer:
t = 54 m + 160
Step-by-step explanation:
I can do the whole explanation unless you just need the answer that's the correct answer
The factors of the quadratic equation is (x + 1) and (x - 6)
Given,
The quadratic equation; -2x² + 10x + 12
We have to find the factors of this equation using quadratic formula;-
Quadratic formula;-
Here,
a = -2, b = 10 and c = 12
Now,
= = = (-10±14) ÷ -4
Solve for,
- 10 + 14 / -4 = -4/4 = -1
That is, (x + 1)
Solve for,
- 10 - 14 / -4 = -24/-4 = 6
That is, (x - 6)
Therefore, the factors for the given quadratic equation is (x + 1) and (x - 6)
