Answer:
[tex]\displaystyle \frac{199}{18}[/tex]
Step-by-step explanation:
Fraction Operations
Before attempting to operate with the given fractions, we need to express all of them in the form a/b, because the last 2 fractions are in mixed form.
[tex]\displaystyle 8\frac{3}{7}=8+\frac{3}{7}=\frac{8*7+3}{7}=\frac{59}{7}[/tex]
[tex]\displaystyle 5\frac{11}{14}=5+\frac{11}{14}=\frac{5*14+11}{14}=\frac{81}{14}[/tex]
Now for the sum of the last two fractions:
[tex]\displaystyle \frac{59}{7}+\frac{81}{14}[/tex]
Make both denominators equal by multiplying by 2 both parts of the first fraction:
[tex]\displaystyle \frac{59}{7}+\frac{81}{14}=\frac{118}{14}+\frac{81}{14}[/tex]
[tex]\displaystyle =\frac{118+81}{14}=\frac{199}{14}[/tex]
Now multiply by 7/9:
[tex]\displaystyle \frac{199}{14}*\frac{7}{9}=\frac{199}{18}[/tex]

John is saving money for a digital camera
that cost $490. So far, he saved $175. If
he will save $50 per week, how many more
weeks does he need to save to buy the
camera? Which of the following
represents the right inequality?
Answer
7 weeks
Step-by-step explanation:
$490 - $175 = $315
John needs $315 still for the camera
divdie $315 by $50 and you get 6.3 but because it cant be 6 weeks he would be short $15 you would have to wait an additional week in order to cover the cost of the camera completly.

What is the product of 8.0 x 10^2 and 7.4 x 10^2 expressed in scientific notation?
Answer:
5.92 × 10^5
Step-by-step explanation:
8.0 × 10²= 800
7.4 × 10²= 740
800 × 740 = 592000
592000 in scientific notation looks like this 5.92 × 10^5
Hope this helps!!
Answer:
5.92 x 10^5
Step-by-step explanation:
The product of the two is 592000 and to do scientific notation you put the decimal after the first number and however many numbers are after that decimal is the number 10 is to the power of. To know if the exponent after the ten is positive or negative if you move the decimal to the right in order to make it the original number it is positive, and if you have to move it to the left then you have a negative exponent after the 10.

Jason and Eddy are traveling from Jacksonville to Miami, which is a distance of 382 miles. According to the American Automobile Association (AAA) map, it takes 1 hour and 54 minutes to travel from Jacksonville to Daytona, 2 hours and 51 minutes to travel from Daytona Beach to Fort Pierce, 1 hour and 23 minutes to travel from Fort Pierce to West Palm Beach, and 1 hour and 38 minutes to travel from West Palm Beach to Miami. If Jason and Eddy follow the AAA guidelines, what would be their average speed (in mph) for the trip
Answer:
The value is [tex]v = 49.23 \ mph[/tex]
Step-by-step explanation:
From the question we are told that
The distance from Jacksonville to Miami is d = 382 miles
The time it take to travel from Jacksonville to Daytona is [tex]t_1 = 1 \ hour\ and\ 54\ minutes = 1 + \frac{54}{60} = 1.9 \ hours[/tex]
The time it take to travel from Daytona Beach to Fort Pierce is [tex]t_2 = 2\ hours\ and\ 51\ minutes= 2 + \frac{51}{60} = 2.85 \ hours[/tex]
The time it take to travel from Fort Pierce to West Palm Beach is
[tex]t_3 = 1\ hour\ and\ 23\ minutes= 1 + \frac{23}{60} = 1.38 \ hours[/tex]
The time it take to travel from West Palm Beach to Miami [tex]t_4 = 1\ hour\ and\ 38\ minutes= 1 + \frac{38}{60} = 1.63 \ hours[/tex]
Generally the average speed is mathematically represented as
[tex]v = \frac{d}{t_1 + t_2 +t_3 + t_4 }[/tex]
=> [tex]v = \frac{382}{1.9 + 2.85 +1.38 + 1.63 }[/tex]
=> [tex]v = 49.23 \ mph[/tex]
Lupus is a medical phenomenon where antibodies that are supposed to attack foreign cells to prevent infections instead see plasma proteins as foreign bodies, leading to a high risk of blood clotting. It is believed that 2% of the population suffer from this disease. The test is 98% accurate if a person actually has the disease. The test is 74% accurate if a person does not have the disease.
If an individual tests positive for lupus, what is the probability that this is a false positive? (In other words, what is the probability of an individual not having lupus, given that they received a positive test result?)
Do not give your answer as a percentage chance, but rather as a decimal probability (i.e., 0.xxx).
Answer: the answer should be lower than because this is the percentage of people who get diagnosed with a disease that is not lupus 0.465 so about 50% or 0.5 hopefully that help I don't know the answer for the amount of people who don't have it and get misdiagnosed there is no information on it based on what I've seen
Step-by-step explanation: Its based on a study from the Lupus Foundation of America

(2x + 25) (5y) (3x - 10) solve for x and y
Answer:
x=35 y=17
Step-by-step explanation:
2x+25=3x-10
3x-2x=25+10
x=35
(3x-10)+(5y)=180
(3(35)-10)+(5y)=180
95+5y=180
5y=180-95
y=85/5
y=17
How many more games will it take until tom and will have scored the same number of points
Answer:
Both players will need to play 7 more games to have the same score.
Step-by-step explanation:
Will makes 18 points per game and Tom makes 21 points per game. Will has a total of 483 points and Tom has 462 points.
We have to calculate the number of games Tom and Will need to play for them to have the same number of points. Since Tom makes more points per game, we're sure it will eventually happen.
Let's call x to the number of games that both players will play. Will will have a number of points equal to:
W = 483 + 18x
And Tom will have:
T = 462 + 21x
For both number of games to be equal, the equation to solve is:
483 + 18x= 462 + 21x
Move 18x to the right side and 462 to the left side:
483 - 462 = 21x - 18x
Operating:
21 = 3x
x = 21 / 3 = 7
Thus, both players will need to play 7 more games to have the same score.
