Answer:.75x200
Step-by-step explanation:
Answer:
8. a = 30
9. a = 3.46
General Formula:
a = square root c^2 - b^2
Answer:
f(10) = 3
Step-by-step explanation:
If f(x) = 
, in order to find the result for f(10) we just need to substitute 10 instead of x and we will get...
1)V=Ixwxh
=5 cm x 3 cm x 2 cm
=30 cm³
2)V=bxh
=(10m x 6m) x 4m
= 60 m² x4 m
3)V=Ixwxh
=3 cm x 3 cm x 3 cm =27 cm³
=240 m³
Answer:
x = 3
Step-by-step explanation:
Mathematically, the mean is the sum of the numbers divided by the count of the numbers
The count of the numbers is 5
Thus;
( 4 + 8 + 9 + x + 2x)/5 = 6
(21 + 3x)/5 = 6
21 + 3x = 6(5)
21 + 3x = 30
3x = 30-21
3x = 9
x = 9/3
x = 3
