To find Enrique's weight, set up a system of equations based on the given information and solve for the weights of both Brendan and Enrique.
Enrique weighs 5 pounds more than twice Brendan's weight.
If their total weight is 225 pounds, you can set up a system of equations.
Let x be Brendan's weight, so Enrique's weight is 2x + 5.
From the given information, x + (2x + 5) = 225.
Solving the equation, x = 70 and Enrique's weight is 2(70) + 5 = 145 pounds.

In a horse race, how many different finishes among the first 33 places are possible if 20 horses20 horses are running? (exclude ties)
To solve this problem, let us break this down one by one.
There are 20 possible
horses that could win in first place. Therefore this means that for each of
these possibilities, there are now 19 horses that could come in second. So
meaning there are 20 x 19 possible combinations for the first 2 places.
20 x 19 = 380. And for each of those combinations, there are also
18 possible horses that could come in the third place. So
20 x 19 x 18 = 6,840
There are 6,840 possible horse combinations for the first 3
places in the race.

There are 325 students in ping pong club. There are 5 girls for every 7 boys in the club. Which is the correct proportion that can be used to determine the number of girls in the club?
To find the number of girls in the club, you can set up a proportion using the given information. Cross-multiply the proportion and solve for the number of girls. The approximate number of girls in the club is 232.
Explanation:To determine the number of girls in the club, we can set up a proportion using the given information. Since there are 5 girls for every 7 boys in the club, the proportion can be written as:
Girls/Boys = 5/7
To find the number of girls, we can solve the proportion by cross-multiplying:
Girls = (5/7) * Total Number of Students
Substituting the given total number of students as 325, we can calculate the number of girls in the club as:
Girls = (5/7) * 325
Girls = 232.14
Therefore, there are approximately 232 girls in the ping pong club.Learn more about Determining the number of girls in a club here:https://brainly.com/question/21322206

Hence, we have:
f(x)= 2x-1 when x ≤ -1
x+4 when x ≥ 1
Step-by-step explanation:After looking at the graph we observe that in the region: x ≤ -1The graph is a straight line that passes through (-1,-3) and (-2,-5)
Hence, the equation of line is:
[tex]f(x)-(-3)=\dfrac{-5-(-3)}{-2-(-1)}\times (x-(-1))\\\\\\f(x)+3=\dfrac{-5+3}{-2+1}\times (x+1)\\\\\\f(x)+3=2(x+1)\\\\\\f(x)=2x+2-3\\\\\\f(x)=2x-1[/tex]

What is Componendo-dividendo rule?Componendo-dividendo rule: A theorem based on the topic of proportions permits a faster way to carry out the calculations and cut down the count of expansions required. It is helpful in situations involving equations with fractions or rational functions. The componendo and dividendo rule are used while studying ratios and proportions. If the ratio of any two given numbers is the same as the ratio of the other 2 numbers, then the ratios of the sum total of the numerator and denominator to the difference of the numerator and denominator of the two rational numbers are equal in nature.
Given, older employee needs 13 hours to shovel the snow.
So in 1 hr the older employee will shovel = 1/13
Younger employee needs 10 hours to shovel the snow.
So in 1 hr the younger employee will shovel = 1/10
Now, when they work together
[tex]1/13+1/10 = 1/x \\(10+13)/130 = 1/x \\3/130 = 1/x\\x = 130/23 = 5.6 hrs[/tex]

Final answer:
Two employees working together can clear the sidewalk in approximately 6 hours and 31 minutes. This is determined by finding the individual work rates, combining them, and then taking the reciprocal of the combined rate to find the total time worked together.
Explanation:
To find out how long it will take two employees to shovel snow together, we need to determine their combined work rate. The older employee takes 13 hours, and the younger employee takes 10 hours. First, we calculate each of their work rates per hour by taking the reciprocal of their time.
So, the older employee's work rate is 1/13 sidewalks per hour and the younger employee's 1/10 sidewalks per hour. To find their combined work rate, we add these two rates together:
Combined work rate = (1/13) + (1/10) = (10 + 13) / (13 × 10) = 23/130 sidewalks per hour
Now, to find the total time taken to shovel the sidewalk when working together, we take the reciprocal of the combined work rate:
Time taken working together = 1 / (23/130) = 130/23 hours
To make this more interpretable, we can convert it into a mixed number:
Time taken working together = 5 hours and (130/23 - 5 × 23/23) hours = 5 hours and 35/23 hours
We can convert 35/23 hours into minutes by multiplying by 60:
Additional minutes = (35/23) × 60 minutes = approximately 91 minutes
Therefore, the time taken working together is roughly 5 hours and 91 minutes, which simplifies to 6 hours and 31 minutes.

If a weighted score for a project is based on just two criteria, fit with strategy, weighted 70% and roi, weighted 30%, what would be the weighted score for a project with scores of 80 on fit with strategy and 50 on roi?
Final answer:
To calculate the weighted score for a project, apply the weights to the scores for each criterion and sum the results. The calculated weighted score for a project with scores of 80 on 'fit with strategy' (70% weight) and 50 on 'ROI' (30% weight) is 71.
Explanation:
To calculate the weighted score for a project based on the provided criteria, you need to apply the weights to the scores for each criterion and then sum the results. In this case, the criteria are 'fit with strategy' which has a weight of 70% and 'ROI' which has a weight of 30%.
The weighted score for 'fit with strategy' is calculated as follows:
(Score for 'fit with strategy' × Weight of 'fit with strategy') = (80 × 0.7) = 56.
The weighted score for 'ROI' is calculated as follows:
(Score for 'ROI' × Weight of 'ROI') = (50 × 0.3) = 15.
To find the total weighted score for the project, you add these two results together: 56 (from fit with strategy) + 15 (from ROI) = 71.
Therefore, the total weighted score for the project is 71.
