6w=30; divide 30 by 6 to the w by itself; the answer is 5
Answer:
- 10.7 liters of paint required
Step-by-step explanation:
Dimensions of the room
- 7.7 m by 14.8 m with the height of 2.4 m
Find the surface area of the 4 walls
- A = Ph = 2(l + w)h = 2(7.7 + 14.8)*2.4 = 108 m²
Convert the area to ft²
- 108 m² = 108*10.7639 ft² = 1162.5012 ft²
Find the amount of paint required
- 1162.5012/410 = 2.84 gal (rounded)
Covert the volume to liters
- 2.84 gal = 2.84*3.76 l = 10.7 l (rounded)
Area of sector = (1/2) * r^2 * α where α = the angle in radians
= 1/2 * 12^2 * π/3
= 72 π / 3 = 24 π Answer
Answer:
5050
Step-by-step explanation:
∑_{n=1 to 50} (4n-1)
a1=4×1-1=3
a2=4×2-1=7
a3=4×3-1=11
......................
......................
......................
a50=4×50-1=199
n=50
Sn=n/2(a1+an)
S50=50/2(3+199)=50/2×202=50×101=5050
Answer:
P = -4
Step-by-step explanation:
Assuming that x = 20 and y = 24, you have to plug in these numbers for x and y to get to this equation P = 20 - 24. You should get -4 when you subtract 24 from 20 giving you a negative answer.
