Please need answers ASAP and please explain how to do it as well thanks
Answer:
-25/42
Step-by-step explanation:
you need to make the denominators equal, so find a number that is divisible by both 6 and 7 (i chose 42 because it’s the first number that comes to mind) you then multiply the numerator by the same number.
so -1/6 is multiplied by 7 on top and bottom to become -7/42, and -3/7 is multiplied by 6 of top and bottom to become -18/42.
then you add them together and you get -25/42
if possible you would simplify but for this one it’s not :)
Answer:
Negative Twenty Five over Forty Two.
Step-by-step explanation:
Hey, It looks like you just have to add two fractions. i.e Negative One Sixth (-1/6) and Negative Three Seventh (-3/7).
First Step: Make the denomimators the same.
-1/6 will become -7/42
-3/7 will become -18/42
Second step: Add the two fractions.
-7/42 + -18/42 = -25/42
So there is your answer: -25/42

A high-performance composite flywheel rotor can spin anywhere between 30,000 and 100,000 revolutions per minute. What
is the range of degrees through which the composite flywheel can travel in a minute? Write your answer in scientific
notation.
Answer:
Step-by-step explanation:
1 revolution will equal 360 degrees
Because of that 30,000 revolution would be 10,800,000 degrees
100,000 rev would equal 36,000,000 degrees
The range through which the composite flywheel rotates in one minute be denoted by ' F ' . (1.08 x 107)° F (3.6 x 107)°
The range of degrees the composite flywheel can travel in a minute is 2.52 × 10⁷ degrees/minute.
What is the Scientific Notation?Scientific Notation is a way of writing down in the easy form of very large or very small numbers.
The range of revolutions per minute for the rotor is from 30,000 to 100,000, which means that the rotor can spin a total of 70,000 revolutions per minute (100,000 - 30,000 = 70,000).
To find the range of degrees through which the composite flywheel can travel in a minute, we need to multiply the range of revolutions by the number of degrees in one revolution.
A full revolution is 360 degrees, so the composite flywheel can travel in a minute :
70,000 revolutions/minute × 360 degrees/revolution = 25,200,000 degrees/minute
This can be written as 2.52 × 10⁷ in scientific notation.

Suppose that you borrow $11000 for 4 years at 6% toward the purchase of a car. Find the monthly payments and the total interest for the loan.
Answer:
The monthly payments ≅ $258.335
The total interest of the loan ≅ $1400.095
Step-by-step explanation:
The rule of the monthly payments is
[tex]M.P=\frac{P(\frac{r}{n})}{1-(1+\frac{r}{n})^{-nt}}[/tex] , where
P is the initial amountr is the rate in decimaln is the period in a yeart is the number of years∵ You borrow $11000
∴ P = 11000
∵ It will be for 4 years
∴ t = 4
∵ The rate is 6%
∴ r = 6% = [tex]\frac{6}{100}[/tex] = 0.06
∵ It is a monthly payment
∴ n = 12
→ Substitute these values in the rule above
∴ [tex]M.P=\frac{11000(\frac{0.06}{12})}{1-(1+\frac{0.06}{12})^{-12(4)}}[/tex]
→ Use your calculator to find the answer
∴ M.P = 258.3353195
∴ The monthly payments ≅ $258.335
→ The total interest of the loan is the difference between the total
of the monthly payments and the initial amount
∴ The total interest of the loan = T.M.P - P
∵ The total of the monthly payments = M.P × t × n
∴ The total of the monthly payments = 258.3353195 × 4 × 12
∴ The total of the monthly payments = $12400.09534
∵ The initial amount P = $11000
∴ The total interest of the loan = 12400.09534 - 11000
∴ The total interest of the loan = 1400.095
∴ The total interest of the loan ≅ $1400.095

9514 1404 393
Answer:
(a, b, c, d) = (2, -3, -2, 2)
Step-by-step explanation:
The horizontal segment where y=3 extends from x = -2 to x = 2. These are the values of c and d, respectively.
The slope of the left piece is up 2 for over 1, so is 2/1 = 2, the value of a.
The slope of the right piece is down 3 for over 1, so is -3/1 = -3, the value of b.
So, we have ...

What is the distance, d, between the points (2,5/2) and (8/3,1)?
Enter your answer in the box. Enter your answer in simplest radical form.
Answer:
um 3 5/4
Step-by-step explanation:
The distance, d, between the points (2,5/2) and (8/3,1) will be; 1.6415 units.
What is the distance between two points ( p,q) and (x,y)?The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
D = √[(x-p)² + (y-q)²]
So, we will use the distance formula:
Let (2, 5/2) be (x₁, y₁) and let (8/3, 1) be (x₂, y₂).
Now Substitute:
D = √[(1 - (5/2))² + (8/3 - 2)²]
Evaluate the expressions within the parentheses;
D = √[(1 - (5/2))² + (8/3 - 2)²]
D = √[(-3/2)² + (2/3)²]
Evaluate:
D = √[9/4 + 4/9]
Square:
D = √97/6
Hence, the distance, d, between the points (2,5/2) and (8/3,1) will be; 1.6415 units.
