It's b. Group all the pounds together and all the volumes together. Small packages weigh 30 lbs (30x), lg pkgs weight 65 lbs (65y) and together they weigh at most 3800 lbs. So 30x + 65y <= 3800 (they divided each of those terms by 5 to get 6x + 13y <= 760). Next take the volumes: small pkgs have a volume of 4 ft^3 (4x) and lg pkgs have a volume of 9 ft^3 (9y) and together they are no more than 400 ft^3. So 4x + 9y <= 400. It's b.
Answer:
V = 3,367.6 cm³
Step-by-step explanation:
Diameter of sphere (D) = 18.6 cm
radius (r) = ½(18.6) = 9.3
π = 3.14
Formula for volume of a sphere = ⁴/3πr³
Plug in the values
V = ⁴/3 × 3.14 × 9.3³
V = ⁴/3 × 3.14 × 804.357
V = (4*3.14*804.357)/3
V = 3,367.57463
V = 3,367.6 cm³ (nearest tenth)
The answer should be 5 over 4
<span>Leroi
and sylvia both put 100 in a savings account.
=> Leroi decides he will put in additional 10$ each week.
=> Sylvia decides to put in additional 10% of the amount in the account each
week.
Now, who has more money after the first additional deposit?
And who has more money after the second additional deposit?
Answer = the answer is the Sylvia
Because at the beginning they both have 100 dollars in their account
Then Leroi deposited 10$ per week which
will become 20$ for 2 weeks and have a total of 120 dollars.
Sylvia also deposited 10% of her money which is also 10$ and on the second week
will be 100 + 10% = 121, she’ll also got a total of 121$.</span>
