Answer:
half
Step-by-step explanation:
Answer:
x = ± 2
Step-by-step explanation:
given
40 - x² = 0 ( add x² to both sides )
40 = x² or
x² = 40 ( take the square root of both sides )
x = ± 
= ± 
= ± 2
10, 0, -10
You just have to subtract by 10
Answer:
C, A and B
Step-by-step explanation:
Tank A holds 40 Liters and 5 fish.
- Volume per fish of Tank A
Tank B holds 100 Liters and 12 fish.
- Volume per fish of Tank B
Tank C holds 180 Liters and 23 fish.
- Volume per fish of Tank C
Therefore, the volume per fish from least to greatest is:
7.83, 8 and 8.33
These correspond to the tanks: C, A and B respectively.
Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
To begin with, let's establish that ( x ) can equal to any number from 0 to 9.
Meaning, that ( x ) is equal to one of the following: 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9.
Now that we know which values ( x ) can equal to, we will simply substitute each of the numbers as potential values of ( x ) into the six-digit number and divide it by 27 to see if it is a multiple of 27.
If X = 0
= 63X904 / 27
= 630904 / 27
= Not a whole number
Therefore, X is not equal to 0.
If X = 1
= 63X904 / 27
= 631904 / 27
= Not a whole number
Therefore, X is not equal to 1.
If X = 2
= 63X904 / 27
= 632904 / 27
= Not a whole number
Therefore, X is not equal to 2.
If X = 3
= 63X904 / 27
= 633904 / 27
= Not a whole number
Therefore, X is not equal to 3.
If X = 4
= 63X904 / 27
= 634904 / 27
= Not a whole number
Therefore, X is not equal to 4.
If X = 5
= 63X904 / 27
= 635904 / 27
= 23552
ANSWER:
Therefore, the answer is:
X = 23, 552
