Answer:
(3.75, 3.5)
Step-by-step explanation:
The weighting factors for the weighted average of the end points are the reverse of the length ratios.
For a 1 : 3 split, the first point is weighted by a factor of 3; the second point is weighted by a factor of 1. The weighted sum is divided by the total of the weights.
(3(3, 2) +1(6, 8))/(3+1) = (9+6, 6+8)/4 = (3.75, 3.5)
Answer:
16 and 25
Step-by-step explanation:
Answer: 16 cm
Step-by-step explanation:
1 centimeter to 5meters conversion means use the ratio 1cm/5m.
80meters * 1 centimeter / 5 meters = 16 centimeter width
Because Ramos spent half of his money, he now has the other half of his money, which is $4.50. Therefore, he originally had:
$4.50* 2= $9.00
The final answer is $9.00~
OK the problem is focusing on VOLUME and TIME.. you can set up this problem like this... (v1/t1) x (v2/t2). first we plug in what we know. the first container was filled in 4 minutes so this is our "T1". However we weren't giving the volume of the first container but we were given its dimensions. the volume formula is LxWxH. so we plug in 9x11x12 to get 1188. this is our "V1". the same concept applies for the volume of the aquarium. we have its dimensions so just plug in. 24x25x33 = 19800 this is our "V2". the thing we are left trying to find is T2. so now you can do some cross multiplying and division. (T1xV2)/V1 or (4x19800)/1188 and you get 66.67min or 1h and 6.67mins. and thats how long it took to fill the aquarium.
