Answer:
B angle 3 and 6 are complementary angles
Answer:
95.49 g
Step-by-step explanation:
D = m/v
Looking for mass so isolate m to form equation format
D × V = m
Plug in numbers
.7892g/mL × 121.0 mL = 95.4932 g
Only g and not g/mL because the mL cancels each other out. It's easier to see if you rewrite it on paper.
Round to sig figs
Both original numbers hold 4 sig figs
95.49 g
Answer:
6/10
Step-by-step explanation:
Answer:
34,000
179,400
39,900
Step-by-step explanation:
In the number 33,762, the 3 is in the thousands place, so we look to the number behind it. If it is less than 5, we round down, and if it is more than 5 we round up.
Since 7 is more than 5, we round up, so our rounded number would be
34,000
Let’s use this logic for the rest of these numbers
179,406
4 is in the hundreds
Previous number in 0 which is less than 5, so it rounds down
179,400
39,994
9 is in the tens place
Previous number is 4 which is less than 5, so it rounds down
39,990
5/6 hour = 5/6 × 60 = 300/6 = 50 minutes
8 tasks in 50 minutes
1 task = 50/8 = 6 1/4 minutes
a. robot completes task in 6 1/4 minutes
b. #tasks per hour =
#of tasks × time takes to do task < or = 60
n × 6.25 = 60
6.25n = 60.
n= 60/6.25 = 9.6
robot can complete 9 tasks in one hour
