ft tall
Step-by-step explanation:
We must follow the indications:
Ryan is 4 1/2 ft. tall.
Ryan =
He is 3 in. taller than his sister Lizzie. to find how tall is Lizzie we need to substract 3 inches from the height of Ryan, but we can only substract the quantities if they are in the same units.
Thus we convert the 3 inches to feet, since we 1 feet = 12 inches:
so the height of lizzie:
we convert the first mixed number to fraction by multiplying 4 by 12 and adding the numerator 1:
the subtraction becomes:
Lizzie is 23/6 ft tall.
She is 3/4 of a foot taller than her sister Emma, thus we must substract 3/4 from the height of Lizzie to find the height of Emma:
Emma is ft tall.
Answer:
12.25

Answer:
The answer would be $1995
Step-by-step explanation:
Trust me
There are 60 bricks in a stack 20 feet high.
2x10=20
If you multiply the 2 by 10, you have to multiply 6 by 10.
6x10=60
So if there are 6 bricks in a 2 feet high stack, there are 60 bricks in a 20 feet high stack.
