Find Surface Area! WILL MARK BRANLIEST PLEASE HURRY!

Answers

Answer 1

Answer:

1164

Step-by-step explanation:

Surface area is the sum of the areas for all the faces. So 20×15= 300 since there is another one like that you multiply that answer by 2. Then 16×12= 192 then repeat and multiply 192 by 2. Then 12×15= 180 and since there is only one you dont multiply it by 2. Now add (192×2) + (300×2) + 192.

384 + 600 + 192 = 1164

Answer:

2.5 counters

Step-by-step explanation:

On the right, there are 8 spheres. Since the scale is balanced, we can assume there is an equivalent of 8 spheres on the left side. We can clearly see three spheres (in red), so we'll subtract that from the 8. The canisters (blue) are the same weight, and make up 5 spheres togther. So, divide by 2, and your answer is the blue canister is equal to 2.5 spheres/counters.

A bag contains only red, green, brown and yellow marbles. The probabilities of selecting each colour are shown below. red=5x green=2x brown=3x yellow=4x Find the probability of selecting a yellow marble. P(Yellow)=?

Answers

Answer:

28.57%

Step-by-step explanation:

In order to find the probability of selecting a yellow marble we first need to calculate the total number of marbles in the bag. We do this by adding the number of individual colored marbles together.

5 + 2 + 3 + 4 = 14 total marbles

Now that we have the total number of marbles in the bag we need to divide the number of yellow marbles by this total to get the probability in decimal form.

4 (yellow) / 14 (total) =  0.2857

Now we need to multiply this decimal by 100 to get the percentage probability.

0.2857 * 100 = 28.57%

Finally, we can see that the probability of selecting a yellow marble is 28.57%

Answers

Answer:
