A.) (-2,-7) is the answer.
Answer:
40! Seconds
Step-by-step explanation:
Calculation for After how many seconds will the two fish tanks have the same amount of water
First step
Based on the information given let the equation be :
150-1/2x=120+1/4x
Second step
Now let solve for x which means that x will be the number of second by multiplying both side by 4
4(150-1/2x)=4(120+1/4x)
=600-2x=480+x
Third step
Let Add 2x on both side
600=480+3x
Third step
Let Subtract 480 on both side
600-480=480-480+3x
120=3x
Last step is to divide both side by 3
120/3=3x/3
40=x
Hence:
x=40 seconds
Therefore After 40 seconds the two fish tanks will have the same amount of water.
Answer:
Hello,
why not 700 ?
Step-by-step explanation:
7*2*10*5=700
Impossible to reach 3000 since 2nd digit is 4 or 8.
Answer:
No for whole number dimensions
Step-by-step explanation:
The area of a rectangle is found using the formula A = l*w. This means for an area of 24 square units the dimensions must be two factors of 24. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24. Using each pair of factors, find if any would have a perimeter of 24 too.
1 and 24 has perimeter 50
2 and 12 has perimeter 28
3 and 8 has perimeter 22
4 and 6 has perimeter 20
It is not possible to draw a rectangle with whole number dimensions which will have area and perimeter 24.
