Answer:

11/12

Step-by-step explanation:

Tap A

1 tank / 3hr = 1/3 tank/1hr

Tap B

1 tank / 8 hr = 1/8 tank /1hr

Tap A + Tap B X 2hr

(1/3/hr +1/8/hr) * 2hr = 2/3 + 2/8 (the hr cancels out) = 8/12 + 3/12 = 11/12

Two movie tickets and 3 snacks are $24.two movie tickets and 5 snacks are $28.how much is a movie ticket and how much is a snack

maks197457 [2]

Answer:

S: $0.18

T: $11.73

Step-by-step explanation:

T=tickets

S=snacks

2t+3s=24

5s=28

Divide 5 with 28.

Roughly $0.18

s=0.18.

2t+3(0.18)=24

2t+0.54=24

Subtract 0.54:

2t+0.54-0.54=24-0.54

2t=23.46

Divide 2:

t=11.73

So A snack is $0.18, and a ticket is $11.73

Hope this helped!

Work out the perimeter of this semicircle with radius 3cm. Give your answer in terms of π

kondaur [170]

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

A semicircle is given with radius of 3cm .

And we need to find the perimeter of the semicircle . We know the perimeter as ,

$:\implies$ Perimeter = πr

$:\implies$ Perimeter = 3cm × π

$:\implies$ Perimeter = 3π cm .

Now there is the diameter of circle is 6cm . Hence totally the perimeter is ,

$:\implies$ Perimeter = 3π + 6 cm

We were supposed to give answers in terms of π .

<h3>Hence the perimeter is ( 3π + 6 ) cm</h3>
