My guess is 3,780 you have to multiply
Answer:
Diameter is 11cm, and the radius is 5.5
Step-by-step explanation:
To get the radius, just divide the size of the circle by 2
Diameter is the same size as the circle
Answer:
x = 5
Step-by-step explanation:
Since these are similar triangles all you need to do is figure out how much "x" has gotten smaller.
First take the line DE length (16) and divide it by line BC (8)
16 / 8 = 2
Now divide line BD by 2
10 / 2 = 5
x = 5
You can approach this question in multiple ways, 2 of which are more obvious.
Method 1). Add up the number of marbles which aren't white divide that by the total number of marbles.
I.e. 8 + 14 + 10 = 32
32/48 = 2/3
[There are 48 marbles in total]
Method 2). Find the total number of marbles, divide the number of white marbles by the total (like method 1), then do 1 minus the answer.
I.e. 16/48 = number of white marbles
1 - 16/48 = 2/3
