WILL GIVE BRAINLIEST ! A marble is picked at random.Without putting the first marble back,a second marble is picked at random find the probability that the fist marble picked is green and the second marble is picked red write your result as a percentage
Answers
Step-by-step explanation:
The percentage is 1/2 * 2/5 = 1/5 = 20%.
The probability that the first marble picked is green, and the second marble is picked red is 20%
What is probability?A probability is a number that reflects the chance or likelihood that a particular event will occur.
Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.
Given that, there are six marbles in total, 3 are green, 2 are red and one is brown,
we need to find the probability that the first marble picked is green, and the second marble is picked red,
So, P(E) = favorable outcome / total outcome
Therefore, the probability that the first marble picked is green, and the second marble is picked red = 3/6 x 2/5 = 6/30 = 1/5 = 20%
Hence, the probability that the first marble picked is green, and the second marble is picked red is 20%

In a certain chemical, the ratio of zinc to copper is 3 to 11. A jar of the chemical contains 385 grams of copper. How many grams of zinc does it contain?
Answers
Answer:
35 grams
Step-by-step explanation:
The ratio of zinc to copper is 3 to 11
A jar of chemical contains 385 grams if copper
Therefore the number of grams of zinc it contains can be calculated as follows
3/11= x/385
11x= 385
x= 385/11
= 35 grams
Hence the chemical contains 35 grams of zinc
How many solutions does 4(3x+2)=4(2x+3) +4x have?
Answers
Final Answer: No Solution. 4(3x + 2) = 4(2x + 3) + 4x has 0 solutions.
Steps/Reasons/Explanations:
Hey there! 8 = 12 would have No Solution because 8 doesn't equal 12. An example of 1 solution is 12 = 12.
Question: How many solutions does 4(3x + 2) = 4(2x + 3) + 4x have?
Step 1: Expand.
[tex]12x + 8 = 8x + 12 + 4x[/tex]
Step 2: Simplify [tex]8x + 12 + 4x[/tex] to [tex]12x + 12[/tex].
[tex]12x + 8 = 12x + 12[/tex]
Step 3: Subtract [tex]12x[/tex] on both sides.

Answer:
question 1 asks about the volume and question 2 asks about the surface area.. I can't see all of question 3... soo I'll give you the first two only
Step-by-step explanation:
this seems like it would be easier to figure out.. if we did the volume of the block that would fit around the odd shape of the foam soooo
the block would be 10 inches tall by 36 inches long by 20 inches in depth
use a calculator.. 10 x 36 x 20 = 7200 [tex]inches^{3}[/tex] is the volume... of just a block that would fit perfectly over that foam structure.. now subtract the two pieces that are not part of the block.. the long rectangle and the triangle off the end.
the first one to subtract is a block that is 8 x 5 x 20= 800
the second piece to subtract is the triagle block that is 18 x 8 so the formula for the area of a triangle is 1/2 base * height = 1/2 (18*8)= 72
7200-800-72=[tex]inches^{3}[/tex] is the total volume of the shape
the surface area is just add up each flat area of the shape
side = 36x10 - 8x5 - 1/2(8x20)
side = 240
5x20 + 8x20 + 5x20 + 10x20 + 20x20 + 2x20 +36x20 + 2(side)= 2200 [tex]inches^{2}[/tex]
