the three friends spent L.120.00, L.240.00, and L.360.00, respectively.
How to solve the problem?
Let's denote the amount that Alicia spends as "x". According to the problem statement, we know that Juan spends twice as much as Alicia, which means he spends 2x. Similarly, we know that Ana spends three times as much as Alicia, which means she spends 3x.
We also know that the three friends together have spent L.720.00. So, we can set up an equation to represent this:
x + 2x + 3x = 720
Simplifying this equation, we get:
6x = 720
Dividing both sides by 6, we get:
x = 120
So, Alicia spent L.120.00, Juan spent twice as much as Alicia, which is L.240.00, and Ana spent three times as much as Alicia, which is L.360.00.
Therefore, the three friends spent L.120.00, L.240.00, and L.360.00, respectively.

• What is the cost price of a bag if it was sold for Rs 500 at a loss of 5%?
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.
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?
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%

Solve the equation 120 + 1814
x = 180 − 134
x for x.
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.
Marcus and Tony work for Lombardo's Pipe and Concrete. Mr. Lombardo is preparing an estimate for a customer. He knows that Marcus lays a slab of concrete in 9 hours. 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.
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.

Do not include com or the dollar sign in your answer.
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

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

is the discount, as a percentage?
Write your answer using a percent sign (%).
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%

A.0.148
B.0.148 repeated
C. 0.3
D.0.3 repeated
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.

mph.
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.
