There was a little error in t= -6 when "t"=2, I think you meant when "r"= 2 when t =-6 so i corrected it before solving.
Answer:r= 7/3
Step-by-step explanation:
Step 1
r varies inversely as t ,written mathematically can be expressed as
r ∝ 1/t
Introducing the constant of proportionality. K we have
r ∝ 1/t
r=Kt
Step 2
Now when r= 2 when t =-6, we have that
r=Kt
2 = K -6,
k=2/ -6= -1/3
Step 3
Find r when t =-7
Using our equation,
r=Kt
r= -1/3 x-7
r= 7/3

Clarissa had a strip of leather that was n yards long. She cut the strip into pieces that were each 1/4yard long, with no leather left over. She used all of the pieces and made 9 bracelets. Which equation represents this situation?
Answer:
I don't know what the options are, but my equation is (1/4) * n = 9
Step-by-step explanation:
n yards
Each strip = 1/4 yard
9 bracelets made
9 = (1/4) * n

Answer:
8 students in each van, 22 students in each bus
Step-by-step explanation:
Let's say v is number of students in each van
and b the number of students in each bus.
Let's make the equations:
8v + 8b = 240
4v + 1b = 54
8v + 8b = 240
v + b = 30
b = 30 - v
now let's use b = 30 - v and insert it into 4v + 1b = 54
4v + (30 - v) = 54
3v + 30 = 54
3v = 24
v = 8
b = 30 - v = 30 - 8 = 22

What is the simplest form for 20:36
Answer:
5:9
Step-by-step explanation:
20÷4=5
36÷4=9
If you divide 20 by 4 you get 5. If you divide 36 by 4 you get 9. You need to be able to divide each number in the ratio by the same number. In this case, that number is 4. You can tell that this ratio (5:9) is in simplest form because 5 is a prime number and cannot be simplified any more.
If you want to check this divide the ratio by 2 two times. Or just divide it by 4 once.
20÷2=10 → 10÷2=5
36÷2=18 → 18÷2=9

Answer:
[tex]x=\frac{5}{k}[/tex]
Step-by-step explanation:
Given expression is,
[tex]\text{log}_{3^k}243=x[/tex]
By using the law of logarithm,
[tex](3^k)^x=243[/tex]
[tex]3^{kx}=243[/tex]
[tex]3^{kx}=3^5[/tex]
By comparing exponents on both the sides of the equation,
[tex]kx=5[/tex]
[tex]x=\frac{5}{k}[/tex]
Therefore, [tex]x=\frac{5}{k}[/tex] will be the answer.

Payday loans are typically $15 charge with an interest rate of 10% over a 2 wk period which variables in the interest formula are known
Answer:
Time = period of loan
Interest amount = $15
Interest rate = 10%
Step-by-step explanation:
Given:
Charge on loan = interest = $15
Interest rate on loan = 10%
Loan period = 2 weeks
The interest formula is given by the relation :
Interest = Principal * rate * time
Using the interest equation given :
The known variables Given in the question are :
Time = period of loan
Interest amount = $15
Interest rate = 10%

in figure 5.19 to the right PQRS is a rectangle. if PS=5cm and PR=13cm find SR and QS.
Given:
PQRS is a rectangle.
[tex]PS=5\ cm,\ PR=13\ cm[/tex]
To find:
The length of SR and QS.
Solution:
We know that, all interior angles of a rectangle are right angle. So, [tex]\angle S=90^\circ[/tex].
According to the Pythagoras theorem, in a right angle triangle,
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
Using Pythagoras theorem in triangle PRS, we get
[tex]PR^2=PS^2+SR^2[/tex]
[tex]13^2=5^2+SR^2[/tex]
[tex]169-25=SR^2[/tex]
[tex]144=SR^2[/tex]
Taking square root on both sides.
[tex]\sqrt{144}=SR[/tex]
[tex]12=SR[/tex]
So, the measure of SR is 12 cm.
We know that the diagonals of a rectangle are equal. PR and QS are the diagonals of the rectangle PQRS. So,
[tex]PR=QS[/tex]
[tex]13=QS[/tex]
Therefore, the length of SR is 12 cm and the length of QS is 13 cm.
Hello, I need help! The question is "Today you will look over the following problem that Nancy worked and explain what she did incorrectly and why it does not work. Then tell me what information Nancy would need to know in order to use this theorem correctly"
Answer:
Step-by-step explanation:
Remark
The ratios are certainly correct but that doesn't mean that they show similarity. SSA is a very dangerous proposition to use. Redraw triangle DEF of that DF is going to upwards to your right hand side. Make E as it was before. Why isn't this right?
It isn't right because E has gone from being an acute angle to an obtuse angle (an angle larger than 90 but less than 180).
The ratios are still true, but the angles do not match. So the whole answer is incorrect.

Machine machine with 140 gallon capacity needs to be filled with water/glycol mixture. Someone has already pump 50 gallons of 60% glycol blend into the machine. How much more glycol must you add an order to get a 50% concentration?
Answer:
40 gal
Step-by-step explanation:
The capacity of the machine is 140 gallons, and it must be filled.
In a 50% glycol solution, the amount of glycol in 140 gallons of solution is
50% * 140 gallons = 70 gallons.
Once the machine is full with 140 gallons of 50% glycol solution, it will have 70 gallons of glycol.
The machine now has 50 gallons of 60% glycol solution.
60% * 50 gallons = 30 gallons
The machine has now 30 gallons of glycol.
70 gal - 30 gal = 40 gal
You must add another 40 gallons of glycol.
