Estimate each elapsed time to the nearest hour

1 answer:

3 0

1. 1:38 AM to 4:38 AM is 3 hours, 4:38 AM to 4:50 AM is 12 mins. This means that total time elapsed is 3 hours and 12 mins. Rounding to nearest hour gives 3 hours.

2. I assume you mean 11:49 AM. 11:49 AM to 6:49 PM is 7 hours. 6:49 PM to 7:12 PM is 23 mins. Total time is 7 hours 23 mins, or 7 hours to the nearest hour.

3. 2:25 PM to 3:25 PM is 1 hour, 3:25 PM to 3:35 PM is 10 mins. Total time is 1 hour 10 mins or 1 hour to the nearest hour.

4. 8:25 AM to 10:25 AM is 2 hours. 10:25 AM to 10:52 AM is 27 mins. Total time is 2 hours 27 mins or 2 hours to the nearest hour.

The trick is to count the number of hours first, then count the number of minutes remaining.

Solve each quadratic equation by factoring and check

max2010maxim [7]

hello : 
the discriminat of each quadratic equation : ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 ) Δ > 0 the equation has two reals solutions : x1,2 = (-b±√Δ)/2a

factoring :

ax²+bx+c = a(x-x1)(x-x2)
2 ) Δ = 0 : one solution : x1 = x2 = -b/2a

factoring :

ax²+bx+c = a(x-x1)²
3 ) Δ < 0 : no reals solutions... no

Show a step-by-step process of solving 7/20 and getting a decimal answer.

Luden [163]

First we have to multiply the numerator and the denominator by 5:
$\frac{7}{20}* \frac{5}{5}= \frac{35}{100}$ = 0.35

The average yearly temperature T in degrees for Newport, Oregon is given by: |T−55|≤10 Find the average temperature range in deg

Nata [24]

Good evening

The absolute value has the following property:

$|x|\leq a\iff -a\leq x\leq a$

Apllying:

$|T-55| \leq 10 \iff -10\leq T - 55 \leq 10\\ \\ -10 + 55 \leq T -55 + 55 \leq 10 + 55\\ \\ \boxed{45\leq T \leq 65}$

The average temperature range is between 45 and 65 degrees.
