Mathematics
1 answer:
Allisa [31]3 years ago
8 0

Answer:

$80

Step-by-step explanation:

2 adults at $20 each

4 children at $10 each

20(2)+10(4)=80

40+40=80

80=80

why multiple 2 by 20?

because there are 2 adults and it costs $20 per adult

why multiple 4 by 10?

because there are 4 children and it costs $10 per child

why add them together?

because they want admission for 2 adults and 4 children so adding them together will give the total price

Ganezh [65]

Answer:

1.38 to the nearest hundredth.

Step-by-step explanation:

Dividing:

x + 1 ) 3x - 1 ( 3            

          3x + 3

                -4

so (3x - 1) / (x + 1) =  3  - 4 / x+ 1

Integral  of (3  - 4 / x+1 )  = 3x - 4 ln(x + 1)

Between  limits of 1 and 2 we have:

(3(2) - 4 ln 3) - (3 - 4 ln2)

=  1.6056 - 0.2274

= 1.3782.

Vitek1552 [10]

Answer:

Steps 1 - 4 below explains it.

Step-by-step explanation:

The way that the soldiers get across the river and leave the boys in joint possession of the boat is;

1) The two 12- year - old boys will take the boat to the other side

2) Thereafter, one of the 12- year - old boys will return with the boat.

3) A soldier will now take the boat to the other side and the soldier will remain there while the other boy returns the boat.

4) Step 1 - 3 is a total of 4 trips. Thus, trip would be repeated the total of n times and the n number of soldiers would get across the river and leave the boys in joint possession of the boat after the total of 4n trips.
