There are 4 blocks in the bag. How many of the 4 blocks do you think are red (R)? The graph shows the results of the first 10 picks.​

1 Red Block

Step-by-step explanation:

2:8 is the existing ratio shown in the graph. And so I think if we divide both sides by 2 we get 1:4 which is what we want. So we take the 1 part which is red. 1 Red Block.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4
