Answer:
Step-by-step explanation:
how many coins: d + q = 200
value of the money .10d + .25q = 44
(ten cents for each dime and 25 cents for each quarter)
Now to solve by elimination:
1)multiply the first row by -10 so that the dimes will cancel out.
-.10d + -.10 q = 20 (don't do anything to second row)
.10d + .25q = 44
2) now add those up.
the dimes cancel out.
.15 q = 64
that does not divide evenly so there is something wrong with this problem.
1197 = 42 × h / 3 ; where h = the height of the pyramid ;
h = ( 3 × 1197 ) / 42 ;
h = 3591 / 42 ;
h = 85.5 feet ;
There are 8 numbers for the computer to choose from.
So the probability of choosing a particular number is 1/8.
The first number can be any one of the 8.
The second and the third must be the same as the first, with probability 1/8.
Therefore the probability that all three numbers are the same
= (1/8)(1/8) = 1/64 [ player will win a prize ]
(=0.03125)

you can pretty much count the units for the base and height off the grid.
