Answer with Step-by-step explanation:

Let Ari has p pennies

Ari has a total of 22 coins consisting of pennies and nickels.

Number of pennies+Number of nickles=22

p+Number of nickles=22

So, number of nickles=22-p

1 nickle=$0.05

So, value of 22-p nickles=$0.05(22-p)

and 1 pennies =$0.01

So, value of p pennies=$ 0.01p

The total value of the coins is $0.54.

this means that

0.01p + 0.05(22-p)=0.54

Hence, the equation which can be used to find the number of pennies Ari has is:

B) 0.01p + 0.05(22 – p) = 0.54

1) 2x11 =<br> I don’t know how to do this
Fynjy0 [20]

Answer:

22, Twenty Two

Step-by-step explanation:

A good way to look at multiplying 11 is that the number, if it’s under 10, will then be two of that number. For instance, 4 x 11 = 44, 6 x 11 = 66, and so on and so forth.

A. Find the totals for each team after two games.
andre [41]
A.
Team 1: (1) + (-3) = 1 - 3 = -2
Team 2: (4) + (-5) = 4 - 5 = -1
B.
Team 2 is winning after two games, as -1 is greater than -2.
C. 
Team 1: (-3) + (1) + (-4) + 4 = -2
Team 2: (4) + (-5) + (9) + (-9) = -1 
No, the results would be the exact same. This is because both Team 1 and Team 2 got scores in game 3 and game 4 that add up to a total of 0, so the only scores that affected the final scores are that from Game 1 and Game 2.

Hope this helped!

A cylinderical container of height 28cm and diameter 18cm is filled with water. The water is then poured into another container
tiny-mole [99]

Answer:

h = 24 cm

Step-by-step explanation:

volume of water in the cylinder = volume of water in the rectangular base container

But ,

volume of cylinder = \pir^{2}h

where:  is the radius and h is the height.

volume of cuboid = length x width x height

                             = l x w x h

So that;

\pir^{2}h = l x w x h

But, r = \frac{diameter}{2} = \frac{18}{2} = 9 cm, height of cylinder = 28 cm, length = 27 cm, width = 11 cm, \pi = \frac{22}{7}.

Thus,

\frac{22}{7} x (9)^{2} x 28 = 27 x 11 x h

\frac{22}{7} x 81 x 28 = 27 x 11 x h

7128 = 297h

h = \frac{7128}{297}

  = 24

h = 24 cm

The depth of the water in the container is 24 cm.
