Answer:
28
Step-by-step explanation:
We can see that all the angles are inside of a triangle and the sum of the interior angle of the triangle is 180 degrees.
Knowing this, we know that the sum of all the angles present is 180 degrees.
1st angle can be seen as 90 degrees, 2nd angle is x+6 and the 3rd is 2x.
The sum can be written as ( 90 + x + 6 + 2x ) and this equals to 180 degrees.
90 + x + 6 + 2x = 180
96 + 3x = 180
( subtract 96 on both sides )
3x = 180 - 96
3x = 84
( divide by 3 on both sides )
x = 84 / 3
x = 28
Since we are asked to find the rate of change from Monday to Wednesday, we are dividing by 2, since Monday is day 1 and Wednesday is day 3. 3 - 1 = 2.
1800 + 500 = 2300 calories consumed Tuesday.
2300 - 100 = 2200 calories Wednesday.
(2200 - 1800)/2 = 400/2 = 200 calories
It realistically could be any number based on the person but the most likely answer is 40 hours.
Answer:
Step-by-step explanation:
To make h subject of the formula ,
Step 1 : Divide both sides by 2pir to isolate (r+h)
Step 2 : Move r to the other side of the equation to isolae h
Answer :
h = s/2pir -r
Answer:
Part 5) Option b
Part 6) Option d.
Step-by-step explanation:
Part 5) we know that
The area of a square is equal to
where
b is the length side of the square
we have
substitute
Solve for b
take square root both sides
Remember that
substitute
Applying property of exponents
Part 6) we know that
The volume of a cube is equal to
where
b is the length side of the cube
we have
substitute
Solve for b
take cubic root both sides
Remember that
substitute
Applying property of exponents
