I'am somewhat confident that some are right because iam not sure your suppose to round the nearst tenth
Set up a proportion.
pounds / milligrams of medicine
195/279 = 130/x
195x = 279 times 130
195x =36,270
x = 36,270/195
x = 186
A patient weighing 130 pounds needs 186 milligrams of medicine.
Answer:
Y = 2x + 7
Step-by-step explanation:
We know that the slope is 2 so it is 2x
To get the y - intercept of 7 we draw the graph.
if we start at point (-1,-4) and use a slope of 2 the point that lands on the y axis is the y intercept. In this case the y intercept is 7.
It kind of looks like your missing something in you problem. But if f(x) = 3 is correct, then it doesn't matter what x is the answer is always going to be 3. So f(4.5) = 3. Most of the time though f(x) means a function of x, so there is an x in the problem. For example: f(x) = 3x, then f(4.5) = 3*4.5 = 13.5.
Answer:
1600
Step-by-step explanation:
P=LxWxH
so P=20x10x8=1600
