Answer:
50%
Step-by-step explanation:
half of 30 is 15
half= 50
Answer:
x<15, probably
Step-by-step explanation:
maybe multiply 2 to each side to eliminate the fraction. so 3x+15<60. subtract 15 to isolate the variable term so 3x<45. divide by 3 to isolate x so x<15. check the work. is the inequality true for all values of x less than 15? let's try the first possible integer value, 14, to be sure. 3(14)+15= 57. so 57/2<30. now 57/2 is 28.5 and 28.5<30 so it seems right

Step-by-step explanation:
In scientific notation you move the decimal over however many spots that the exponent's number gives
Answer:
The formula for 'h' is
.
The height of the cylinder is 3 in.
Step-by-step explanation:
Given,
Surface Area of Cylinder = 251.2 sq. in.
Radius = 5 in
We have to find out the height of the cylinder.
Solution,
We know that the Surface area of cylinder is given as;

Here 'r' is the radius and 'h' is the height.
We have to solve this for 'h'.

Hence The formula for 'h' is
.
Now we solve for 'h'.
Since 
On putting the given values, we get;

Hence The height of the cylinder is 3 in.
