Hi! So when you are dividing or multiplying a decimal by 10, it becomes a lot easier than it looks. If you divide by 10, you move the decimal to the left one space. If you multiply the decimal by 10, you move the decimal to the right one space. Because you are diving 12.5 by 10, you move the decimal to the left one space, which then becomes 1.25. So, Lauren has run 1.25 miles. If you want to double check, you can multiply 1.25 by 10, which comes out to 12.5. Your answer is 1.25! Hope this helps!!
Substract 3 from the total and divide it with 2
one of them is 5 and the other one is 8.
the answer is
30 x 5 + 9 x 5
Answer:
4.8 months
Step-by-step explanation:
First, let's write down the information that we are given.
Plant A:
Initial Height: 3 in.
Constant Rate of Growth (CRG): 2in/month (2 inches per month)
Plant B:
Initial Height: 1 in.
CRG: 29in/year (29 inches per year)
We can see that Plant B grows 29 inches per year, so lets convert Plant B's 'CGR' to months.
Plant B - Divide by 12 (12 months in a year)
29/12 in/year
Now, Lets put these into equations:
Plant A: y = 2x + 3
Plant B: y = 29/12 x + 1
Now, set these two equations together and solve for x.
2x + 3 = 29/12 x + 1
2 = 5/12 x
4.8
So, after 4.8 months, the plants will be the same height.
Answer:
(3/4)a
Step-by-step explanation:
The angle at K is 120°, so the angle at L is its supplement: 60°. That makes triangle FKL an equilateral triangle with a base of FL = a. The vertex at K is centered over the base, so is a/2 from G.
The midsegement length is the average of GK and FL, so is ...
midsegment = (GK +FL)/2 = (a/2 +a)/2
midsegment = (3/4)a
