5.0000 grams or 5000.0 milligrams
Five significant figures.
Answer:
x=27, y=18
Step-by-step explanation:
Angle CB is 128, which means angle AC is 72. We can confirm angle O is also 72, since the lines are straight. Angle AM is 27, because AN is a right angle. 63+72+27= 162 180-162=18 Angle ND is 18.
Answer:
The time required by both persons to complete the work T = 1.458 hours
Step-by-step explanation:
Given data
Time required by Joe to clear a lot
= 2.5 hours
Time required by his partner to clear a lot
= 2.5 hours
Time required by both persons to complete the work by working together
![T = \frac{T_1 T_2}{T_1 + T_2}](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7BT_1%20T_2%7D%7BT_1%20%2B%20T_2%7D)
![T = \frac{(2.5)(3.5)}{2.5 + 3.5}](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7B%282.5%29%283.5%29%7D%7B2.5%20%2B%203.5%7D)
T = 1.458 hours
Therefore the time required by both persons to complete the work T = 1.458 hours
Answer:
n = 16
Step-by-step explanation:
3n + 4 = 52
subtract 4 from each side
3n+4 -4 = 52-4
3n = 48
divide by 3 on each side
3n/3 = 48/3
n = 16
Answer: 42in
Step-by-step explanation: 7in times 6 sides= 42 in
