Answer:
A. -12 meters
B. 28 meters
C. 40 meters
Step-by-step explanation:
The surface of the ocean would be 0.
Taking this into account, 12 meters below would be 0 - 12, which is -12. Therefore A's elevation would be -12.
For the sea bird, 28 meters above the surface, which is again 0, would be 0 + 28. B's elevation is 28.
Since the fish is 12 meters below the surface and the sea bird is 28 meters above the surface, simply add the two numbers up to get a total of 40 meters. C would be 40 meters.
False; 4cd cannot be added with 8c because their variables don’t match up therefore meaning they cannot be added together.
Answer:
The tank is 10cm high
Step-by-step explanation:
Given
-- length
-- width
--- water lever
Required
The height of the tank
Let y represents the remaining fraction before water is added.
So:
Make y the subject
Solve
Represent the volume of the tank with v
So:
Make v the subject
Substitute:
Represent the height of the tank with h;
So, the volume of the tank is:
Make h the subject
Substitute values for v, l and w
Convert 30L to cm^3
Answer:
1.2347
Step-by-step explanation:
First we will put the expression within the brackets and then we'll solve it.
(((6/(3/8)*0.5) / 1.44) / 4.5
Now we will solve it according to the BODMAS rule:
BODMAS is a useful acronym that lets you know which order to solve mathematical problems. It is a short form for Brackets, Of, Division, Multiplication, Addition and Subtraction.
<em>So according to this rule first we will solve the term 3/8 inside the round bracket</em>
by dividing 3 by 8 we get:
= 3/8 = 0.375
Now the expression becomes:
(((6/0.375)*0.5) / 1.44) / 4.5
Now we will solve the term 6/0.375
By dividing 6 by 0.375 we get:
= 6/0.375 = 16
Now the expression becomes:
((16*0.5) / 1.44) / 4.5
Now we will solve the round bracket with the term 16*0.5
16*0.5 = 8
The expression becomes:
(8 / 1.44) / 4.5
Now divide 8 by 1.44
8/1.44 = 5.556
Finally we have the final term to solve:
= 5.556 / 4.5
= 1.23466666667
By rounding off we get:
= 1.2347
<u>The answer we get is = 1.2347</u>
