Answer:
B. 13
Step-by-step explanation:
Solve this by setting up system of equations:
0.25x + 0.10y = 3.95
x + y = 20
x equals the number of quarters and y equals the number of dimes. 0.25 is the value of a quarter and 0.10 is the value of a dime.
1. Multiply one equation to have the same coefficient as the other
0.10 · (x + y = 20) = 0.10x + 0.10y = 2
2. Subtract to find the value of one variable
0.25x + 0.10y = 3.95
<u>- 0.10x + 0.10y = 2</u>
0.15x = 1.95
3. Solve for x by dividing both sides by 0.15
x = 13

X < 43, implies that the height of Aisha is less than 43 and can't be equal to 43 ( as there is no equal operator)
A is wrong as the inequality does not imply that Aisha is 0 tall , but any height height from 0 to 42.99999...
B) Correct , Aisha is not 43 and less she is less than that.
C) no, she may just need to grow 1 or 2 inches who knows.
D) nope, Aisha is at most 43 ( at least = 43 or taller)
at most 43 or less
Answer:
48 ft cubed or 576 in cubed
Step-by-step explanation:
The volume of the water is 2304 in cubed. you multiply 12 in by 24 in by 8 in.
the rock makes the water go up 2 in. You then multiply 12 in by 24 in by 10 in. This will equal 2880 in cubed.
2880-2304=
576 in. cubed or 48 ft. cubed
