If R is the midpoint of QS, QR = 6x – 51 and RS = 2x – 7, find QS.
Answers
Answer:
QS = 30
Step-by-step explanation:
Since R is the mid point QR = RS
Given QR = 6x – 51 and RS = 2x – 7 then
6x – 51 = 2x – 7, isolate like terms
6x -2x = 51 -7 , combine like terms
4x = 44, divide both sides by 4
x = 11
QS = QR + RS
QS = 6x -51 +2x -7 , combine like terms
QS = 8x - 58, substitute x= 11 in the equation
QS = 8*11 -58, multiply 8 and 11
QS = 88 -58
QS = 30

Ruby is saving up to buy a new jacket. She already has $25 and can save an additional $7 per week using money from her after school job. How much total money would Ruby have after 10 weeks of saving? Also, write an expression that represents the amount of money Ruby would have saved in ww weeks.
Total savings after 10 weeks:
Total savings after ww weeks:
Answers
From the question;
1) Ruby will save $95 after ten weeks
2) The equation for ww weeks is; S = $25 + ($7 x ww)
What is an equation?
Total savings after 10 weeks:
Ruby saves $7 per week from her after school job, and she already has $25, so her total savings after 10 weeks can be calculated as follows:
Total savings = Initial savings + (Weekly savings x Number of weeks)
Total savings = $25 + ($7 x 10)
Total savings = $25 + $70
Total savings = $95
So, Ruby would have a total of $95 after 10 weeks of saving.
Expression for the amount of money Ruby would have saved in ww weeks:
Let "S" represent the total savings after ww weeks.
Expression: S = $25 + ($7 x ww)

A statistician predicts that the probability of Wisconsin losing their next football game is 914. What are the odds for them winning? Write your answer as 1:2 which is reduced as much as possible.
Answers
Since the probability of them winning is 5/14, the odds of them winning is 5:14.
Probability of the team losing = 9/14
Probability of the team winning will then be: = 1 - 9/14 = 5/14
It should be noted that in order for us to get the probability of then winning, we have to subtract the fraction from 1 which was what was done above.
Therefore, it can be deduced that since the probability of them winning is 5/14, the odds of them winning is 5:14.

2nd answer, and 5 hours
Step-by-step explanation:
Section 1
The answer is the 2nd one down. The tickets are selling at a rate of
floor tickets: 100/h; stand tickets: 75/h
Since the stand tickets were selling 150 in 2 hours, only 75 were sold per hour.
Section 2
There are only 375 stand tickets left to sell.
Every 2 hours 150 are sold or you can also say 75 per hour.
If you're selling 75 per hour, you would divide 375 by 75 which would give you 5 hours to sell out the stands tickets.
375/75 = 5 hours

Answer:
[tex]x<=118[/tex]
Step-by-step explanation:
We already have [tex]10300[/tex] kilograms, we will add [tex]x*150[/tex] kilograms, and we need it to be less than or equal to [tex]28000[/tex].
So, the inequality is [tex]150x+10300<=28000[/tex].
We can subtract [tex]10300[/tex] from both sides to get [tex]150x<=17700[/tex].
We then lastly divide by [tex]150[/tex] on both sides to get [tex]x<=118[/tex].
So, the answer is [tex]\boxed{x<=118}[/tex] and we're done!

Use the graph of the quadratic function, g(x), to answer each question.

b.g(-3) =
c. Find x when g(x) = 4.
X =
Answers
We can establish the quadratic function in vertex form:
g(x) = -(x + 5)^2 + 4
To find the value of g(-1):
Substitute -1 as the input of the function:
g(-1) = -(x + 5)^2 + 4
g(-1) = -(-1 + 5)^2 + 4
g(-1) = -(4)^2 + 4
g(-1) = -12
To find the value of g(-3):
Substitute -3 as the input of the function:
g(-3) = -(x + 5)^2 + 4
g(-3) = -(-3+ 5)^2 + 4
g(-3) = 0
To find the value of x when g(x) = 4:
Since your vertex is (-5, 4), in which the y-coordinate is 4, then its x-coordinate is -5.
Therefore, the value of x when g(x) = 4 is -5.

You are selling flowers for a fundraiser . You pay $ 1.50 for each flower plus a flot rate delivery fee of $ 15 . You are selling the flowers for $ 3 . At least how many flowers do you need to sell to make a profit ?
Answers
Answer:
15÷1 .50=10
Because you are already paying a flat rate of $15. You make 1.50 off of each flower. So you have to sell over 10 flowers to make a profit.
At least 11 flowers should be sold to make a profit.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that is equal.
Given:
Total cost for the buying flower = 1.5 * number flowers + 15
For n=10 = 1.5 * 10 + 15
= 30
By selling 10 flowers =10 * 3
= $30
For n =11 = 1.5 * 11 + 15
= 31.5
By selling 11 flowers = 11 * 3
= 33
Therefore, At least 11 flowers should be sold to make a profit.

Which number is the greatest?
A the square root of 125
B the whats root of 30
Answers
Answer:
B) √(30)
Step-by-step explanation:
A: The cube root of 125 is 5 because 5^3, or 5 × 5 × 5, equals 125.
B: The square root of 30 is between the numbers 5 and 6, meaning 30 is between 25 and 36. The square root of 30 is about half-way in between 5 and 6, so we can say √(3) ≈ 5.5
Now, when we compared 5.5 and 5, 5.5 is obviously greater. Therefore, the correct answer is B √(30).
