Answer:
Step-by-step explanation:
Total number of tools for both = 564.
Dr Brown used 386 tools for 6 experiments.
average number of tools per experiment used by Dr Brown = 
= 64
Dr Rachal used 236 tools for 8 experiments.
average number of tools per experiment used by Dr Rachal = 
= 29
i. The number of more experiment that can be done by Dr Brown = (564 - 386) ÷ (64
)
= 2.7668
Dr Brown can do two more experiments.
The number of more experiments that can be done by Dr Rachal = (564 - 236) ÷ (29
)
= 11.1186
Dr Rachal can do 11 more experiments.
ii. Number of tools left after Dr Brown's experiments = 564 - 386
= 178
Number of tools left after Dr Rachal's experiments = 564 - 236
= 328
Answer:
18π
Step-by-step explanation:
Lateral Surface Area = 2πrh
Plug in the numbers into the equation.
but leave the pi
Answer: One
Step-by-step explanation:
7x(7) + 7(2) = 7(x + 2)
49x + 14 = 7x + 14
49x = 7x
x = 0
Answer:
2+27x = 110°
Step-by-step explanation:
Since both lines are parallel, the angles are same side interior angles, which mean they both add up to 180°.
(16x+6)+(2+27x) = 180°
Move them to each side:
16x+27x = 180-6-2
43x = 172°
x = 4°
Verify:
110°+70° = 180°
I'm pretty sure the answer is: <u><em>h = 9</em></u>
<u><em></em></u>
<u><em>Reason:</em></u>
The question tells us that to complete the equation that represents the relationship between d and h, so for "d", its d = 1, for h, it is 9 per each "days"
from the hours.
