An urn contain 2 white marbles, 3 green marbles, and 5 red marbles. A marble is drawn and then replaced. Then a second marble is drawn. What is probability that the first marble was white and the second was green?
Answer:
1/5
Step-by-step explanation:
To find this you would need to multiply the probability of pulling a white marble to the probability of pulling out a green marble.
1)First you would need the probability of pulling out a white marble. There are 10 marbles in total and out of those 2 are white. So the probability of pulling out a white marble would be 2/10. If you simplify that you would get 1/5 for the probability of pulling out a white marble.
2)Next, you would find the probability of pulling out a green marble. Using the same process that we used to find the probability of pulling out a white marble, we would find the answer to be 3/10. All that we did here was green marbles/total marbles. By filling that in we got 3/10 for the probability of pulling out a green marble.
3)Now all that is left is doing probability of pulling a white marble × probability of pulling out a green marble. This would be 1/5 × 3/10. After solving the answer would be 3/15 which we would simplify down to 1/5 as our final answer.

We require to find the total number of words, that is 100%
Given 15% = 90 words
Divide 90 by 15 to find 1% and multiply by 100 for total , that is
number of words = [tex]\frac{90}{15}[/tex] × 100 = 6 × 100 = 600 ords

Step-by-step explanation:
Anthony is practicing kicking field goals for his high school football team. He knows that the field goal is 10 feet off the ground.
Part A: If he stands 40 feet from the field goal, how far must he kick the ball in order to make the extra point?
Part B: Explain how you arrived at your conclusion.
Answer: The answer is 41.23.
Step-by-step explanation:
You have to find the hypotenuse of the triangle so we are going to use the formula a^2+b^2=c^2.
The first thing we need to do is substitute 40 and 10 in for a and b which would give you 40^2+10^2.
Next you will multiply 40x40 and 10x10 which gives you 1600+100.
Lastly you want to add these together to get 1700 and then you can just search up square root of 1700 and you get 41.23.
Hope this helps!!
Find the missing angle.
Answer:
50°
Step-by-step explanation:

= 180 - 130
= 50
Therefore the missing angle is 50°.
Answer:
50
Step-by-step explanation:
60+70=130

if ben makes $35.00 per hour and then gets a ten percent raise what is his new salary. Show your work
Answer:
$38.50 per hour
Step-by-step explanation:
10% = 0.1
0.1 × 35.00 = 3.50
35.00 + 3.50 = 38.50
Answer:
The answer is $38.50
Step-by-step explanation:
35 x 0.1 = 3.5 (0)
35 + 3.50 = 38.50
The reason we do 0.1 is because 10% written in decimal form is 0.1 and since 35.00 is a decimal we made the percent into a decimal to make it even.

Answer:
Step-by-step explanation:
Substitution method:
y= -2x + 2
x - 2y = 6
so y = (-2x + 2)
Substitute into y
Hence x - 2y = 6 is:
x + 2x +2 = 6 (+2x because there was - in the equations so -×- = +)
3x + 2=6
Then bring 2 to the other side so
3x = 6-2
3x = 4
x = 3/4 or 0.75
To find y :
y= (-2 × 3/4) + 2
y = -1.5 +2
y = 0.5
That's all I can do for now!

A cylinder with height h and radius r. Her work is shown below. V = four-thirds (8) cubed. V = four-thirds (512). V = StartFraction 2,048 Over 3 EndFraction meters cubed. What is Yolanda’s error?
Yolanda should have found the volume by multiplying 8 by Two-thirds.
Yolanda should have found the volume by multiplying 8 by Four-thirds.

Kelly's Cafe offers two kinds of espresso: single-shot and double-shot. Yesterday afternoon, the cafe sold 4 single-shot espressos and 6 double-shot espressos. What percentage of the espressos sold were single-shot?
Answer:
40% of espresso was single-shot.
Step-by-step explanation:
To make a percentage, you need to think of a fraction first. The denominator is always 100 in a percent. If my answer is 40%, the fraction would be 40/100. If there was 6 double shots and 4 single shots, those two together would make 10. 10 x 10 is 100. So really, you just have to multiply 4 by 10 to get the percentage.

one - third the difference between 3/4 and 1/5
11/60 will be the one - third the difference between 3/4 and 1/5.
What is simplification?
When a mathematical expression is converted into an equivalent, typically shorter statement, it becomes simpler. Procedure simplification is one way for promoting consistency in job effort, cost, and duration. It removes diversity and variation that is harmful, meaningless, or superfluous.
Given, two fractions 3/4 and 1/5
Difference between these two fractions = 3/4 - 1/5
Difference between these two fractions = 15/20 - 4/20
Difference between these two fractions = 11/20
One-third of the difference = [tex]\frac{11}{20} * \frac{1}{3}[/tex] = 11*60
Therefore, The one-third difference between 3/4 and 1/5 will be 11/60.

''Create your own word problem where the answer is ⅝. It should be solved using multiplication''
Answer:
Hi, your answer will be 5/8 x 2/8.
Step-by-step explanation:
When multiplying fractions, you are to do both the numerators and denominators. So, if you do 5/8 x 2/8, that would result as 10/16. When you simplify, that would be 10/16 divided by 2, which is 5/8.
Hope this helps! :)
