Answer:Carlos and his family arrived at 10:30
Step-by-step explanation:
The time Carlos and his family left for the amusement park =8:35
Since The trip took 1 hour 55 minutes., we have to add it to the time they left for the amusement park to now the time they arrived
8: 35 =8 hrs 35minutes
<u> 1 hr 55 minutes</u>
<u> 90 minutes </u>
but 90minues is greater than 60 so we convert to hours and minutres by dividing by 60 giving us
90/60=1.5hrs=1hr 30mins
8¹ hrs 35minutes
<u> 1 hr 55 minutes</u>
<u> 10hrs 30 minutes </u>
Therefore, They arrived at 10:30
Answer: Reliability

Answer:
Volume of emerald = 294.22cm³
Step-by-step explanation:
Given that
Mass of emerald = 812.04grams
Density of emerald = 2.76grams/cm³
Volume = ?
The equation for this relationship is ρ = m / V in which ρ is density, m is mass (kg or g) and V is volume (cm³ or m³) making the density unit kg/m³ or g/cm³.
Therefore from
Density = mass/volume
Volume = Mass/density
i.e
Volume of emerald = Mass of emerald / Density of emerald
Volume of emerald = 812.04grams / 2.76grams/cm³
Volume of emerald = 294.2174cm³ ~294.22cm³
Volume of emerald = 294.22cm³
Let x = number of $10 coins.
The total number of coins is 44, therefore there are (44-x) $20 coins.
Total value:
10x + 20(44-x) = 620
-10x + 880 = 620
-10x = -260
x = 26 (number of $10 coins)
44-x = 44-26 = 18 (number of $20 cons)
Answer:
26 $10 coins
18 $20 coins
Answer:
Alternative A
Step-by-step explanation:
2x(x² + 2x - 6)
2x³ + 4x² - 12x
