Step-by-step explanation:
ratio = 3:1:15
amount of sand needed = (15/19)*125 / 3 + 1 +15 =19
Ten point seventy five to nearest tenth is 10.8
Answer:
option 4
Step-by-step explanation:
<u>Given</u><u> </u><u>Equation</u><u> </u><u>:</u><u>-</u><u> </u>
=> -4| x + 9 | = -8
<u>To </u><u>FinD</u><u> </u><u>:</u><u>-</u><u> </u>
=> Solution of the equation .
<u>Solving </u><u>it </u><u>:</u><u>-</u><u> </u>
=> -4| x + 9 | = -8
=> | x + 9 | = -8/-4
=> |x + 9| = 2
=> ( | x + 9 | )² = 2²
=> x + 9 = ±2
=> x = -9 +2 , -9-2
=> x = - 7 , -11
Option 4 is correct.
Poster standard dimension: 8.5 inches by 11 inches
Both length and width of the poster may vary 1/20%
∴ length and width may vary 1/20 % = 0.05% = 0.0005
∵ Area = Width * Length
∴ Area = 8.5 * 11 = 93.5 in²
Smallest acceptable area for one poster:
Width: 8.5 * (1 - 0.0005) = 8.49575 in.
Length: 11 * (1 - 0.0005) = 10.9945 in.
∴ The smallest area = 8.49575 * 10.9945 = 93.4065 ≈ 93.407 in².
