Answer:

Step-by-step explanation:

Note that

(a + b)² = a² + 2ab + b²

Jacky baked some biscuits.he kept 3/7 of the biscuits in container A.5/8 of the remainder in container B and rest in container C

Colt1911 [192]

Let "b" represent the number of biscuits Jacky baked.
.. container A holds (3/7)b
.. container B holds (1 -3/7)*(5/8)b = (5/14)b
.. container C holds (1 -3/7 -5/14)b = (3/14)b = 168

Then
.. b = 168/(3/14) = 784

Jacky baked 784 biscuits.

The basic ratio of 25:40 would be 5:8.

Since 25:40 is equivalent to the fraction 25/40, you would simplify.

25 (divided by) 5 = 5

40 (divided by) 5 = 8

So, the answer is 5:8.

Answer:

The speed of the boat is 20 km/hr

Step-by-step explanation:

Let s be the speed of boat in still water

Let d be the distance

Upstream speed = s-4

Jane took 30 min to drive her boat upstream to water-ski at her favorite spot.

So, Distance traveled in upstream = $Speed \times time =(s-4) \times \frac{30}{60}$

Downstream speed = s+4

So, Distance traveled in downstream = $Speed \times time =(s+4) \times \frac{20}{60}$

So, $(s-4) \times \frac{30}{60}=(s+4) \times \frac{20}{60}$

30s-120=20s+80

10s=200

s=20

Hence The speed of the boat is 20 km/hr
