Ответ:
10 * 5 * 5 = 250
2 * 18 * 5 = 180
15 * 7 * 5 = 525
Answer
missing = 7
Ответ:
7
Step-by-step explanation:
Formula of joint variation :![z = kxy](/tpl/images/0091/4564/158b2.png)
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 .
