An urn contains 10 red balls, 20 yellow balls, and 60 orange balls. If you reach into the urn and select a single ball at random, what is the probability of selecting a orange ball?
Answers
Answer:
2/3 or 67%
Step-by-step explanation:
To find the exact probability for you to reach into the orange balls you'll have to do a data table on which you'll include how many orange balls are by the total amount of balls that are within the urn.
For example:
The urn contains:
* 10 red balls
* 20 yellow balls
* 60 orange balls
Total amount of balls that you have on the urn is 90, you'll get this result by doing a simple addition of the table of content.
Afterwards, we have to find the probability, so you will have to take the amount of orange balls (which is 60) and divide it by 90 (Which is the total amount of balls you have on the urn).
60/90
A quick tip for you to do this on a simplified manner is by dividing the numerator and the denominator by their greatest common divisor (Which in this case is 30) (30x2 = 60) (30x3 = 90)
60/90 = (60 divided 30) / (90 divided 30) = 2/3
To resolve this problem, we get that the probability of selecting an orange ball is 2/3 or approximately 0.67 which we'll simplify to 67%

Answers
A website is selling barbecue grills for $94, but mentions that they originally cost $200 the discount, as a percentage, is 53%.
The discount is the difference between the original price and the discounted price.
Discount = $200 - $94 = $106
To find the percentage discount, we need to calculate what percentage of the original price the discount represents:
Percentage discount = (Discount/Original price) x 100%
Percentage discount = ($106/$200) x 100%
Percentage discount = 53%

• What is the cost price of a bag if it was sold for Rs 500 at a loss of 5%?
Answers
Answer:
526.32
Step-by-step explanation:
Let's assume that the cost price of the bag is "C".
Selling Price = Cost Price - Loss
We get:
500 = C - 0.05C
500 = 0.95C
C = 500/0.95
C ≈ 526.32
Therefore, the cost price of the bag was approximately Rs 526.32.
A roller for construction work is 5 feet in diameter. When the roller has made one turn, how far has it
traveled?
Answers
Answer:
Approximately 15.7 ft
Step-by-step explanation:
We want to find the circumference of the circle
C = pi * diameter
C = pi *5
C = 5pi ft or approximately 15.7 ft
C = 2πr
where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
We are given that the diameter of the roller is 5 feet. The radius of the roller is half of the diameter, which is:
r = d/2 = 5/2 = 2.5 feet
Substituting this value in the formula for the circumference, we get:
C = 2πr = 2π(2.5) = 5π
Therefore, when the roller has made one turn, it has traveled a distance equal to 5π feet (approximately 15.7 feet).

a cable technician working fo the local cable company needs to lay down cable down through the neighborhood below. He is unsure how much cable cable he needs, though. Use the pythagorean theorem to help him find the length in feet of cable he needs to fufill his duty
Answers
Let's say the distance he needs to cover is 1000 feet and there is a height difference of 200 feet between the two points.
Using the Pythagorean theorem, we can find the length of cable he needs:
c² = a² + b²
where c is the length of the cable, a is the distance he needs to cover, and b is the height difference between the two points.
Plugging in the values we have:
c² = 1000² + 200²
c² = 1,040,000
c = √1,040,000
c ≈ 1,020.62
Therefore, the technician needs approximately 1,020.62 feet of cable to fulfill his duty.
Janeesa lives 247.5 miles away from her grandmother, and the speed limit on that stretch of

lunch on time!
How much faster over the speed limit does Janeesa need to drive to make it on time? Round to the
tenths place if your answer isn't a whole number.
mph.
Answers
distance = rate x time
In this case, the distance is 247.5 miles, the time is 4 hours, and the rate is what we're trying to find. Rearranging the formula to solve for rate, we get:
rate = distance / time
Plugging in the values we know, we get:
rate = 247.5 / 4 = 61.875
So Janeesa needs to travel at an average speed of 61.875 miles per hour to make it to her grandmother's birthday lunch on time. Since the speed limit is 55 miles per hour, she would need to drive 6.875 miles per hour faster than the speed limit. Rounding to the tenths place, that's about 6.9 miles per hour over the speed limit. However, it's important to remember that speeding is dangerous and can result in serious accidents. It's always better to leave earlier and plan ahead to avoid the need to speed.
Janeesa needs to drive about 6.9 mph faster than the speed limit to make it on time.
What is the speed limit
To find out how fast Janeesa needs to drive to make it on time, one can use the formula:
distance = rate x time
In this case, the distance is 247.5 miles, the time is 4 hours, and the rate is what we're trying to find. Rearranging the formula to solve for rate, we get:
rate = distance / time
Plugging in the values we know, we get:
rate = 247.5 / 4 = 61.875
To know how much faster Janeesa needs to drive, one has to subtract the speed limit from the required speed:
Speed Difference = Required Speed - Speed Limit
= 61.875 mph - 55 mph
= 6.875 mph
Therefore, Janeesa needs to drive approximately 6.9 mph faster than the speed limit to make it on time.

The balance on the loan at the end of month 4 is approximately $289,836.23.
We are given that;
Amount borrowed= $290,000
Time 25 years
Payment= $1, 530.73
Now,
To calculate the balance on the loan at the end of month 4, we can use the following formula2:
Balance = (Loan amount - Debt payment) * (1 + Interest rate / 12) - Debt payment
Where:
Loan amount is the original amount borrowed ($290,000)
Debt payment is the amount of principal paid in each monthly payment ($564.06 for the first month and $565.94 for the second month)
Interest rate is the annual interest rate divided by 100 (0.04)
Plugging in the values, we get:
Balance = ($290,000 - $564.06) * (1 + 0.04 / 12) - $565.94 Balance = $289,435.94 * 1.003333 - $565.94 Balance = $290,402.17 - $565.94 Balance = $289,836.23

Tony lays the same size slab in 3 hours. If both work on the job and the cost of labor is $48.00 per hour, decide what the labor estimate should be.
Answers
If both Tony and Marcus work on the job and the cost of labor is $48.00 per hour then labor estimate for the job is $576.00.
Marcus: 1 slab / 9 hours = 1/9 slab per hour
Tony: 1 slab / 3 hours = 1/3 slab per hour
The total amount of work they can do in one hour is the sum of their individual rates:
Marcus and Tony: 1/9 + 1/3 = 4/9 slab per hour
So together, Marcus and Tony can lay 4/9 of a slab per hour.
time = work / rate
time = 1 / (4/9) = 2.25 hours
total labor cost = hours worked x cost per hour
The total number of hours worked is the sum of the hours worked by Marcus and Tony:
total hours worked = 9 hours + 3 hours = 12 hours
The cost per hour is $48.00, so the labor estimate for the job is:
total labor cost = 12 hours x $48.00/hour
= $576.00
Therefore, the labor estimate for the job is $576.00.

Answer: B. The rotation of a pair of parallel lines is a pair of parallel lines.
Explanation: A translation of a line is a displacement of the line, or a transformation which moves all points of the line, without changing its shape or orientation. This means that a pair of parallel lines will remain parallel after a translation.
A rotation of a line is a transformation in which all points of the line are rotated around a pivot point, and the line will change its orientation.
A reflection of a line is a transformation in which all points of the line are reflected across a single axis. This means that a line will remain a line after a reflection.

Solve the equation 120 + 1814
x = 180 − 134
x for x.
Answers
Answer:
Step-by-step explanation:
The equation given is:
120 + 1814x = 180 - 134x
We can simplify this equation by adding 134x to both sides:
120 + 1948x = 180
Next, we can subtract 120 from both sides:
1948x = 60
Finally, we can solve for x by dividing both sides by 1948:
x = 60/1948
Therefore, the solution is:
x = 0.0308 (rounded to four decimal places)
Answer:
To solve the equation, we need to first convert the mixed numbers to improper fractions:
120 + 18 1/4 x = 180 − 1 3/4 x
120 + 73/4 x = 180 - 7/4 x (converting mixed numbers to improper fractions)
Multiplying both sides by 4 to eliminate the fractions, we get:
480 + 73x = 720 - 7x
Combining like terms, we get:
80x = 240
Dividing both sides by 80, we get:
x = 3
Therefore, the solution for x is 3.

work out the some of the interior angles of a pentagon
Answers
"Although part of your question is missing, you might be referring to this full question: Work out the sum of the interior angles of a pentagon".
A pentagon is a polygon with five sides. We can use a formula to get the pentagon's interior angle total. According to the formula, (n-2) x 180 degrees can be used to calculate the total of any polygon's internal angles. This formula can be changed to n=5 for a pentagon, giving us (5-2) x 180 degrees = 540 degrees. Consequently, a pentagon's internal angles add up to 540 degrees.
The sum of the interior angles of a pentagon can also be computed by dividing it by the number of sides, and the result can then be subtracted from 180 degrees to determine each inner angle. So, a pentagon's internal angles are each (540/5)-180 degrees, or 108 degrees.
In conclusion, a pentagon's interior angles add up to 540 degrees, and each interior angle is 108 degrees. In order to solve mathematical problems involving polygons, it can be helpful to comprehend the formulas used to calculate these numbers.

Help plsssssssssssssssssssssssssssss
Answers
Answer:
180 square inches
5 x 6 = 32.5
32.5 x 4 = 130
5 x 5 = 25
25 x 2 = 50
130 + 50 = 180
Step-by-step explanation:
first find the area of all the sides (length times width)
width = 5
length = 6.5
5 x 6.5 = 32.5
32.5 is the area for one side. there are 4 others identical to it
32.5 (one side) x 4 (the amount of sides identical) = 130
then you need to find the area for the bottom/top side
5 = length
5= width
5(L) x 5(W) = 25
25 is the area for the bottom. the top is identical to it
25(bottom side) x 2 (the amount of sides identical)
now add all of the sides up
130 + 50 = 180

Answer: The answer to your question is C. Brainliest?
Step-by-step explanation:
For the first square, we can multiply both the numerator and denominator by 5 to get an equivalent fraction with a denominator of 60:
2/12 = (2 x 5) / (12 x 5) = 10/60
For the second square, we can multiply both the numerator and denominator by 4 to get an equivalent fraction with a denominator of 60:
2/15 = (2 x 4) / (15 x 4) = 8/60
Now, we can add the two fractions:
10/60 + 8/60 = 18/60
Simplifying this fraction by dividing both numerator and denominator by 6, we get:
18/60 = 3/10
Therefore, the total shaded area in the diagram is 3/10 or 0.3 in decimal form.
The answer is C. 0.3.
