Suppose 3 rooms cost $596 and 5 rooms cost $860. Write an equation that represents the total cost for the number of rooms.

Buses to exeter leave a bus station every 20 minutrs busses to plymouth leave the bus satation every 16 minutes a bus to eveter

frez [133]

Answer:

9:20 am

Step-by-step explanation:

The cycles will coincide again at the least common multiple of the cycle times.

20 min = 4 × 5 min

16 min = 4 × 4 min

The least common multiple of these times is 4 × 4 × 5 min = 80 min. 80 minutes after 8 am is 9:20 am.

The two buses will next leave at once at 9:20 am.

Answer: 8/9

Step-by-step explanation:

3x/7 = 8/21, find x

Step 1: cross multiply the equation

3x × 21 = 8×7

63x = 56

Divide both sides by 63; retain in fraction.

x = 56/ 63

x = 8/9

Answer:

1. The square root of 100

2.c=27.11

d=13.96

e=12.6

Step by step explanation: 

1. 2×50=100 the geometric mean is the square root of 100

2. The diagram is made up of three right angled triangles the big outer one and two triangles inside the big one thus we can use the pythagorean theorem to come up with expressions which will help us in solving the unknown parts as below.

c²=30²-d²

c²=e²+24²

d²=e²+6²

both the following add up to c² meaning they are equal:

c²=30²-d²

c²=e²+24²

thus

30²-d²=e²+24²

I want to remain with d² only thus;

30²-24²-e²=d²

900-576=324 (squareroot of 324=18) so

d²=18²-e² and d²=e²+6²

both the above add up to d² meaning they are equal thus;

18²-e²=e²+6²

18²-6²=e²+e²

324-36=2e²

318=2e²

159=e²

e=12.61

Thus d²=e²+6²

d²=12.61²+6²

d²=159+36

d²=195

d=13.96

c²=e²+24²

c²=12.61²+24²

c²=159+576

c²=735

c=27.11

 

I hope this helps
