the temperature t at which water boils is inversely proportional to the number of feet F the water is above sea level. write the related variation equation
Answer:
Water temperature in an ocean varies inversely to the water’s depth. Between the depths of 250 feet and 500 feet, the formula
T
=
14
,
000
d
gives us the temperature in degrees Fahrenheit at a depth in feet below Earth’s surface. Consider the Atlantic Ocean, which covers 22% of Earth’s surface. At a certain location, at the depth of 500 feet, the temperature may be 28°F.
The related variation equation where k is the constant of proportionality is [tex]t=\frac{k}{F}[/tex]
For inverse variation, if a is inversely proportional to b. This is expressed as:
[tex]a \alpha \frac{1}{b}[/tex]
Introducing the constant of variation will give;
[tex]a=\frac{k}{b}[/tex]
Applying the concept to the question:
If the temperature t at which water boils is inversely proportional to the number of feet F, this is expressed as:
[tex]t \alpha \frac{1}{F}[/tex]
[tex]t=\frac{k}{F}[/tex]
Hence the related variation equation where k is the constant of proportionality is [tex]t=\frac{k}{F}[/tex]

I need help i'm not that good at this stuff.
Answer: 40
Reason: Okay, so we can see that the line is travelling in a straight line. When we look closely at the graph, we can see that for every two minutes, it makes 80 bottles, and so on and so fourth. We know it makes 80 bottles in two minutes, so let's divide it by two to find out how many bottles it makes in one minute. (Equation for this = 2x = 80) After dividing, we find out that the machine makes 40 bottles per minute
Check: 40 bottles, and multiply it by 2, and we get 80 bottles per two minutes, and that's correct.
I hope this helps, and Happy Holidays!

A TV has an original price of $499. What is the new price after a 15% increase?
Given:
Original price of a TV = $499
Price increased by 15%.
To find:
The new price of the TV.
Solution:
According to the question,
New price of the TV = Original price + 15% of its original price.
[tex]\text{New price of the TV}=499+\dfrac{15}{100}(499)[/tex]
[tex]\text{New price of the TV}=499+74.85[/tex]
[tex]\text{New price of the TV}=573.85[/tex]
Therefore, the new price of the TV is $573.85.

Every 3 days Ronnie spends 1.5 hours on homework and 2.25 hours on chores. At this rate how many total hours will he spend on homework and chores in 9 days
Answer: 11.25 hours
Step-by-step explanation:
From the question, we are informed that every 3 days Ronnie spends 1.5 hours on homework and 2.25 hours on chores.
At this rate number of hours that he will spend on homework and chores in 9 days will be:
= 9/3 [1.5 hours on homework + 2.25 hours on chores]
= 3 [1.5 hours on homework + 2.25 hours on chores]
= 4.5 hours on homework and 6.75 hours on chores]
Total hours = 4.5 + 6.75 = 11.25 hours
Answer:
11.25

The sum of two numbers is 8. When four times the smaller
number is added to two times the larger number, the result
is 18. What is the larger number?
7
6
5
4
Answer:
x+x=8
that's mean: 2.x/4 + 4.x/1 = 18/1
we find at least a common multiple of 4 and multiply the units by 4
2x + 16x = 72
18x = 72/:18
x = 4
Answer: 7
suppose: the smaller number is a
the larger number is b
because The sum of two numbers is 8 => a + b = 8 (1)
four times the smaller number is added to two times the larger number, the result is 18 => 4a + 2b = 18 (2)
(1)(2) => a + b = 8
4a + 2b = 18
<=> a = 1
b = 7
=> the larger number is 7

Say you are considering two loans. Loan F has a nominal interest rate of 5.66%, compounded monthly. Loan G has a rate of 6.02%, compounded semiannually. Which loan will give the lower effective interest rate, and how much lower will it be?
A) Loan G's effective rate will be 0.091 percentage points lower than Loan F's
B) Loan G's effective rate will be 0.058 percentage points lower than Loan F's
C) Loan F's effective rate will be 0.302 percentage points lower than Loan G's
D) Loan F's effective rate will be 0.149 percentage points lower than Loan G's
Answer:
C) Loan F's effective rate will be 0.302 percentage points lower than Loan G's
Step-by-step explanation:
Formula for effective rate is;
r_eff = [1 + (r/n)]^(n) - 1
Where;
r is interest rate
n is the number of compounding periods per year
Loan F has a nominal interest rate of 5.66%, compounded monthly
Thus: r_eff = [1 + (0.0566/12)]^(12) - 1 = 0.0581
Loan G has a rate of 6.02%, compounded semiannually.
Thus;
r_eff = [1 + (0.0602/2)]^(2) - 1 = 0.0611
Differece = 0.0611 - 0.0581 = 0.003
Converting to percentage gives : 0.003 × 100 = 0.3%
Thus,correct answer is option C
Answer:
C. Loan F’s effective rate will be 0.302 percentage points lower than Loan G’s.

DF= 33
Step-by-step explanation:

Since DE=18 and EF=15 you simply add and = 33
Answer:
df=33
Step-by-step explanation:
The variables a and b represent the legs of a right triangle. The variable c represents the hypotenuse. Use the Pythagorean theorem to find the missing side. Write exact answers using radicals when necessary. A = 3, c = 5, find b.
Given:
a and b are two legs of a right triangle and c is hypotenuse.
a=3 and c=5
To find:
The value of b.
Solution:
According to the Pythagoras theorem,
[tex]hypotenuse^2=(leg_1)^2+(leg_2)^2[/tex]
Using Pythagoras theorem, we get
[tex]c^2=(a)^2+(b)^2[/tex]
Now, putting a=3 and c=5, we get
[tex]5^2=(3)^2+b^2[/tex]
[tex]25=9+b^2[/tex]
[tex]25-9=b^2[/tex]
[tex]16=b^2[/tex]
Taking square root on both sides.
[tex]\pm \sqrt{16}=b[/tex]
[tex]\pm 4=b[/tex]
The measure of side of a triangle cannot be negative. So, only value of b is 4.
Therefore, the value of b is 4.
