Mathematics
1 answer:
azamat3 years ago
7 0

Answer:

9/100

Step-by-step explanation:

There are 10 marbles in the bag

There are 3 pink marbles.

P (1st marble pink) = pink marbles/ total marbles

                              = 3/10

We put the marble back.

There are 10 marbles in the bag

There are 3 pink marbles.

P (2nd marble pink) = pink marbles/ total marbles

                                      = 3/10

Multiply the probabilities together

P (pink, then pink) = 3/10 * 3/10 = 9/100

Jacob makes a scale drawing for a crate with a scale
olga55 [171]

Answer:

  6 inches long and 4 inches wide

Step-by-step explanation:

The dimensions of the actual crate are 20 times those on Jacob's drawing. The dimensions on the builder's drawing are 1/10 of those, so (1/10)(20) = 2 times the dimensions on Jacob's drawing.

The dimensions on the builder's scale drawing are 6 inches long by 4 inches wide.

‼️EXPLAIN PLS ILL MARK YOU BRAINLEST ‼️​
MakcuM [25]
Angle 3: 24 degrees- the angle across from it is 24 which makes this one 24 so it’s congruent.
Angle 1 and 4: 78 degrees- on one side of these angles (the line the seperates it running parallel) the angles total to 180 degrees, we take angle 3 which was 24 and subtract that from 180. That equals 156 which we then divide into two because we have two angles left to solve for which makes 78 each.
Angle 2: 71 degrees- We know angle 3 is 24 and we have a written angle as 85. Knowing each side of these angles equals 180 degrees, we add 85 and 24 to get 109. We then will subtract 180 from 109 to get our missing angle which is 71 degrees.

I hope I could help :)
