Answer:
7
Step-by-step explanation:
Formula of joint variation :
To Calculate k
Width(x)= 7
Height(y) = 12
Volume(z) = 420
Substitute the values in the formula
Now , to find the missing height
Substitute width = x = 15
Height = ?
Volume = z = 525
Substitute the values in the formula :
So, the missing value is 7 .
Answer: The answer is 20 eggs.
Step-by-step explanation: Given that a scientist placed fish eggs in a tank. Also, each day, twice the number of eggs from the previous day hatch, .i.e, if 'x' number of eggs hatch on first day, then '2x' number of eggs will hatch on the second day.
The number of eggs that hatch on the sixth day is given by 5 times 2 to the second power.
So, the number of eggs got hatch on the sixth day is
Thus, the answer is 20 eggs.
Answer:
y = - x + 2
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 2x + 3y = 6 into this form
subtract 2x from both sides
3y = - 2x + 6 ( divide all terms by 3 )
y = - x + 2 ← in slope-intercept form
