Answer:
Divide the weight of the bag by 2.
Step-by-step explanation:
Every time we divide the weight of bags by 2 we always get the number of marbles in this situation.
For example, in the first one:
Weight of bag is 20
Number of marbles is 10
20/10 = 2 or 20 / 2 = 10
On bag number 5 the weight is 100 grams (Add 20 every time)
100/2 = 50
The number of marbles in a bag that weighs 100 grams is 50.
50 marbles
Answer:
A = P * a / 2
A = 81.25
Step-by-step explanation:
We have that there is a corresponding formula for a regular decagon, which depends on the apothem and the perimeter, it is the following:
A = P * a / 2
In this case, the perimeter is the sum of all the sides, that is, 10 sides, therefore:
P = 10 * 3.25
P = 32.5 meters
We replace:
A = 32.5 * 5/2
A = 81.25
Which means that for that regular decagon, the area is 81.25 square meters.
Answer: Correct answer is (x, y) → ( x − 3, y − 4); (5, −1)
Step-by-step explanation: Starting from point 8,3 we go down 4 on the y-axis (y-4)and stopping at -1 then we go left on the x-axis (x-3) stopping at 5.
So the new coordinate for the vertex C should read 5,-1.
Answer:
<h2>3. Divide all terms by 5</h2>
