a zucchini plant in darnell's garden was 14 centimeters tall when it was first planted.since then,it has grown approximately 0.7

avanturin [10]

Let's start with part B. if it was originally 10 cm tall and it goes up 0.5 cm. each day, then we know that to go up one cm it needs two days. With that information we can say that 8*2 = 16. So it needs 17 days to go up 8.5 cm which would make it 18.5 cm tall.

The circumference is 12 mile. What is the diameter?

photoshop1234 [79]

To find the diameter of a circle, using only the circumference, you need to divide the circumference by π, or 3.14.

So in this case, you must divide 12 by 3.14, which gives you 3.82.

I even double checked this, and should be correct then.

A probability is the number of desired outcomes divided by the number of total outcomes.

We have the following sample space

That is, the possible outcomes.

b - b - b

b - b - g

b - g - b

b - g - g

g - b - b

g - b - g
