1 boy can work about 0.3 hours
i think that’s the answer,but good luck
Step-by-step explanation:
let's look at the full numbers under the square roots when bringing the external factors back in :
sqrt(9×9×2) - sqrt(3×3×7) + sqrt(8) - sqrt(28)
and let's present these numbers as the product of their basic prime factors
sqrt(3×3×3×3×2) - sqrt(3×3×7) + sqrt(2×2×2) - sqrt(2×2×7)
now we see that we have 2 pairs of square roots : 1 pair ends with a factor of 2, and one pair with a factor of 7.
let's combine these
sqrt (3×3×3×3×2) + sqrt(2×2×2) - sqrt(3×3×7) - sqrt (2×2×7)
and now we move the factors of 2 and 7 back out in front (of course, we need to apply the square root on these factors) :
9×sqrt(2) + 2×sqrt(2) - 3×sqrt(7) - 2×sqrt(7) =
= (9+2)×sqrt(2) - (3+2)×sqrt(7) = 11×sqrt(2) - 5×sqrt(7)
and that is the first answer option.
Answer:
c. The caplet form is the most expensive
Step-by-step explanation:
A pharmacist is trying to determine which of the form is most expensive. These tablets form comes in 50 mg tablets and these tablet cost is 75.00 for 100 tablets. Capsule comes in 75 mg capsule and cost is 63. 75 for bottle of 85 capsules caplet comes in 100 mg.and 40 caplets are cost of $ 70.00.
Based on these information caplet form is most expensive
